The inertial navigation system includes a new method of zero-velocity updates that accommodates nearly all modes of motion. The design of a particle filter with an optimal importance function to refine the tracking of a user is presented. Experimental data are used to assess the potential accuracy of the indoor geolocation method. C1 [Torrieri, Don] USA, Res Lab, Adelphi, MD 20783 USA.

The ISPA algorithm provides interference suppression prior to the acquisition of a direct-sequence signal. The design of the receiver front end, the DSP implementation, and the emulation of both algorithms have been performed. Emulations show increased interference suppression of at least 30 dB beyond what can be obtained from the processing gain of the direct-sequence signal. Moreover, the algorithms are effective in both far-field and near-field interference environments. The implementations use an SB- and four-antenna square monopole array with each antenna connected to a separate receiver. In one implementation, the acquisition/tracking is done via hardware, and the sampled I-Q baseband outputs of each receiver are digitally processed by the algorithm. In the other implementation, which acts as a software-defined radio, the second IF signals are sampled directly, and the respective DSP units perform acquisition/tracking and algorithm operations.

GP IEEE TI Switch-and-Navigate: Controlling Data Ferry Mobility for Delay-Bounded Messages SO 2011 - MILCOM 2011 MILITARY COMMUNICATIONS CONFERENCE LA English DT Proceedings Paper CT Military Communications Conference (MILCOM) CY NOV 07-10, 2011 CL Baltimore, MD AB We consider the problem of controlling mobile data ferries for message delivery among disconnected, scattered domains in a highly partitioned network. Existing work on data ferry control mostly focuses on predetermined ferry routes, assuming full observations at the ferry and no explicit Quality of Service (QoS) constraints on the resulting communications. In this paper, we aim at designing a QoS-enabled ferry control solution, which handles both partial observations and bounded message delays. To this end, we extend our previous work on data ferry control with partial observations into a comprehensive hierarchical framework called Switch-and-Navigate (SAN), which consists of a global switch policy for determining the best domain to visit and a local navigation policy per domain for searching for nodes within individual domains. Under the assumption of Markovian node mobility, both the global and the local control problems are formulated as Partially Observable Markov Decision Processes (POMDPs) to maximize the discounted effective throughput over all domains. Due to the fact that the optimal solution to POMDP is PSPACE-hard, we develop heuristic policies and further approximations for efficient computation. Simulation results show that the proposed policies can significantly improve the performance over predetermined alternatives. C1 [Ma, Liang; Leung, Kin K.] Imperial Coll, London, England.

The US Army CERDEC Space and Terrestrial Communications Directorate Joint SATCOM Engineering Center (JSEC) is doing relevant research and development in order to provide the best SATCOM OTM technology for transition to the Warfighter. Part of this is the development of a technical test and characterization capability for SATCOM OTM systems. This SATCOM OTM Lab will utilize both motion simulator based testing and vehicle based testing on APG cross-country courses. The SATCOM OTM Lab will support a multitude of development and testing capabilities, but will focus on measuring acquisition and tracking performance. This paper will focus on the motion simulator based SATCOM OTM test and characterization approach, to include a way to simulate operation, given a specified motion profile, over a full range of elevation angles. The recent technical achievements in developing this technical capability will be discussed. Initial test data will be presented and technical challenges will be addressed.

The paradigm of software oriented architecture (SOA) is generally presented as an efficient approach to tackle the lack of technical interoperability between joint tactical land systems. This paper present a practical experiment, between representative US and France chain of command, that focuses on a collaborative mission planning Web Service (WS). The operational expectation is to improve mutual understanding between allied forces to better perform assistance requests between ground supports (logistic, medevac, ...) and to improve coordination between combat units. The mission planning service has been implemented through Web technologies like SOAP, UDDI and XML Schema and relies on the CERDEC TITAN Workflow Orchestration Service. It also uses proactive and reactive planning computation to analyze Friendly Course of Action (FCOA) at preparation time as well as during mission execution. Hosted by the C4ISR OTM team, contributions and main results of the experiments are detailed. Results highlight the benefit of WS design in spite of highly complex functionalities, the interest for automated functions encapsulation and also assess shared awareness involvement in the joint tactical planning process.

Examples of new Ka-band commercial systems abound (Inmarsat-5, ViaSat-1 and Jupiter-1) and WGS is just opening up the government Ka-band in a big way. Land, sea, and aero communications-on-the-move (COTM) applications are being proposed and developed in each of these bands. While these systems are new and highly anticipated, it does not naturally follow that one band or type of system is better than another for all purposes. For example, much of the increased directivity of Ka-band relative to Ku-band is offset by more restrictive off-axis EIRP spectral densities (ESD) limits in the commercial Ka-band. These limits are much less restrictive in the government Ka-band. Similarly, while Ka-band rain fade is a critical issue for land and sea mobile terminals, it does not pose any difficulty for aeronautical terminals, which normally operate above the weather. Each band and system has its strengths and limitations. This paper compares the relative merits of each of these bands and the types of systems being developed for different mobile applications. We examine the performance and coverage of similar size mobile terminals in each band, paying close attention to the differences in regulatory limitations and satellite performance in each band. Finally, we draw conclusions about which bands and types of systems might best fit the different mobile applications. C1 [McLain, Chris; Gonzalez, Lino] LinQuest Corp, San Diego, CA 92123 USA.

Even with the best planning, the environment at the time of the experiment is unpredictable, making large scale controlled experiments difficult to impossible to perform. At the U. S. Army Research Laboratory (ARL) we are using the EMANE (Extensible Mobile Ad-hoc Network Emulation) environment to supplement and extend live experiments in a controlled environment. Our emulation environment includes locally developed tools for real-time path loss calculations using the Longley-Rice irregular terrain model implemented on GPGPUs (General Purpose Graphics Processing Units). This real-time path loss calculation capability allows for the integration of virtual devices with live experiments and forces modeling and simulations. Live experiment integration is identified as one method to increase the perceived scale of the MANET to live participants and increase the repeatability of the experiment. This emulation system is currently being scaled to 1000s of CPU cores and emulated radios through the use of high performance computing assets and approaches. We will present this emulation platform in the context of the performance analysis of a MANET application, namely VoIP (Voice over IP).

These limitations are partially attributable to the large density of dislocations in these devices that arise due to heteroepitaxial growth of high AlN mole fraction III-Nitride semiconductors and act as non-radiatve recombination centers that reduce efficiency and increase debilitating heating. An approach to mitigating this problem is to incorporate nanometer scale compositional inhomogeneities within the AlGaN (NCI-AlGaN) active region of a UVLED that can enhance the internal quantum efficiency by concentrating carriers within regions of narrow bandgap surrounded by a wider band gap matrix. In this paper we report on the growth and characterization of NCI-AlGaN alloys deposited by plasma-assisted molecular beam epitaxy. Growth under N-limited and nearly stoichiometric growth conditions promote the spontaneous formation of these NCI regions. This is attributed to lower adatom mobility of group III and N species on the AlGaN layer surface under these conditions as well as the formation of beneficial surface faceting. Optical characterization by both temperature dependent, time-resolved and time-integrated photoluminescence demonstrates the capability for NCI regions to suppress non-radiative recombination in these active regions despite the presence of a large density of defects. However, reduction of the defect density, both dislocations and impurities, improves the performance of these active regions. (C) 2011 WILEY-VCH Verlag GmbH & Co.

Our approach relies on the sparse representation of a test sample with respect to all training samples in a feature space induced by a kernel function. Projecting the samples into the feature space and kernelizing the sparse representation improves the separability of the data and thus yields higher classification accuracy compared to the more conventional linear sparsity-based classification algorithm. Moreover, the spatial coherence across neighboring pixels is also incorporated through a kernelized joint sparsity model, where all of the pixels within a small neighborhood are sparsely represented in the feature space by selecting a few common training samples. Two greedy algorithms are also provided in this paper to solve the kernel versions of the pixel-wise and jointly sparse recovery problems. Experimental results show that the proposed technique outperforms the linear sparsity-based classification technique and the classical Support Vector Machine classifiers.

These types of conditions present thermal work strain challenges which unmitigated can lead to collapse (heat exhaustion) or even death from heat stroke. Physiological measurement of these teams provides a mechanism that could be an effective tool in preventing thermal injury. While indices of thermal work strain have been proposed they suffer from ignoring thermoregulatory context and rely on measuring internal temperature (IT). Measurement of IT in free ranging ambulatory environments is problematic. In this paper we propose a physiology based Dynamic Bayesian Network (DBN) model that estimates internal temperature, heat production and heat transfer from observations of heart rate, accelerometry, and skin heat flux. We learn the model's conditional probability distributions from seven volunteers engaged in a 48 hour military field training exercise. We demonstrate that sum of our minute to minute heat production estimates correlate well with total daily energy expenditure (TDEE) measured using the doubly labeled water technique (r(2) = 0.73). We also demonstrate that the DBN is able to infer IT in new datasets to within +/- 0.5 degrees C over 85% of the time. Importantly, the additional thermoregulatory context allows critical high IT temperature to be estimated better than previous approaches. We conclude that the DBN approach shows promise in enabling practical real time thermal work strain monitoring applications from physiological monitoring systems that exist today.

When coupled with data-driven mathematical models, CGM data can be used for short-term prediction of glucose concentrations in diabetic patients. In this study, we present a real-time implementation of a previously developed offline data-driven algorithm. The implementation consists of a Kalman filter for real-time filtering of CGM data and a data-driven autoregressive model for prediction. Results based on CGM data from 3 different studies involving 34 type 1 and 2 diabetic patients suggest that the proposed real-time approach can yield similar to 10-min-ahead predictions with clinically acceptable accuracy and, hence, could be useful as a tool for warning against impending glucose deregulation episodes. The results further support the feasibility of "universal" glucose prediction models, where an offline-developed model based on one individual's data can be used to predict the glucose levels of any other individual in real time.

Modulation classification is a challenging task, especially in a noncooperative environment, owing to the lack of prior information on the transmitted signal at the receiver; the problem will be more challenging in the multipath fading channel. The proposed AMC method based on optimal decision fusion by using wireless sensor networks provides a more accurate classification result than any one of the individual signal alone. Wireless sensor networks offer increased reliability and optimal decision fusion provides huge gains in overall classification performance as compared to that of the single sensor. Thus, optimal decision fusion based AMC by using wireless sensor networks greatly enhances classification performance of weak signals in non-cooperative communication environment. Classification performances of optimal decision fusion based AMC by using wireless sensor networks in the multipath fading channel are investigated and evaluated in terms of correct classification probability. Through Monte Carlo simulations, we demonstrate that the proposed AMC algorithm can greatly outperform that of single sensor in multipath fading channel.

Although much of the information is lost in the received signal due to the low sampling rate, we hypothesize that each wide-bandwidth radar data record can be modeled as a superposition of many backscattered signals from reflective point targets in the scene. In other words, our proposed technique is based on direct sparse recovery via orthogonal matching pursuit using a special dictionary containing many time-delayed versions of the transmitted probing signal. Using data from the U. S. Army Research Laboratory (ARL) Ultra-Wideband (UWB) synthetic aperture radar (SAR), we show that the proposed sparse-recovery model-based (SMB) technique successfully models and synthesizes the returned radar data from real-world scenes using only an analytical waveform that models the transmitted signal and a handful of reflectivity coefficients. More importantly, the reconstructed SAR imagery using the SBM technique with data sampled at only 20% of the original sampling rate has a comparable signal-to-noise ratio (SNR) to the original SAR imagery. For comparison purpose, the paper also presents SAR images recovered from conventional interpolation techniques and the standard random projection based compressed sensing technique, both of which resulted in very poor SAR image quality at the same sub-Nyquist sampling rate (20%).

A proof of principle experimentation considers a limited but challenging dataset of calibrated LWIR HS data cubes for four skin tone diverse human subjects, standing outdoors at three distinct ranges. An algorithm is developed to capitalize on two spectral features suitable for small sample size targets, using all of the available bands. The algorithm maps the two spectral features-each consisting of sample sizes significantly smaller than the number of frequency bands, as it simultaneously generates two large sets (reference and testing) of independent contrasts in a lower dimensional subspace. The large sample size in the new subspace allows for the development of a strong hypothesis test that functions as a canonical target detector. Results using real HS imagery are encouraging for a specific face detection scenario, where the range is assumed to be known a priori-200, 300, 400ft. C1 USA, Res Lab, Washington, DC 20310 USA.

The proposed algorithm generalizes the Sparse Kernel-based Ensemble Learning (SKEL) technique, developed previously by the authors. SKEL optimally and sparsely weights and aggregates an ensemble of individual SVM classifiers which independently conduct learning within their corresponding randomly selected spectral feature sub-space using a Gaussian kernel. This ensemble decision is fully optimal, if the dimensionality of the randomly selected feature subspaces and the initial number of the sub-classifiers are determined optimally and is sub-optimal, otherwise. This sub-optimality issue is addressed by taking a bottom-up approach. Individual sub-classifiers are added one-by-one optimally to the ensemble until the ensemble converges. The feature subspace of each individual classifier is optimally selected. The ensemble is modeled as a Quadratically-Constrained Linear Programming (QCLP) problem and optimized by combining Multiple Kernel Learning (MKL) with a greedy, non-linear integer programming method for non-monotonic sparse feature sub-space selection. Hyperspectral image data as well as multivariate data are used to verify the performance improvement of the proposed GKEL algorithm over SKEL in detecting difficult targets.

Full wave simulation results of the meshed patch antenna are presented to demonstrate its use as a communications antenna and to predict its performance as a chemical/gas sensor. The patch antenna exhibits a center frequency of 27.85 GHz with a -10 dB bandwidth of 2.1 GHz (7.5%). The patch center frequency shifts approximately 60 MHz in direct response to the change in carbon nanotube permittivity that occurs due to the presence of a reacting gas.

China will likely become a major player in Arctic trade routes and become a main destination for goods shipped through the Northern Sea Route. It is likely that a significant part of future Russian oil and gas production will ultimately be supplied to China. What are the strategic implications of China's active involvement in Arctic politics? The Arctic "Great Game" is often described as a new Cold War between the United States and Russia. Regionally, the two main protagonists are Russia and Norway. This article makes a different argument. The Arctic has recently become an issue on the Russo-Chinese, and possibly Russo-Japanese security agenda. The first goal of this article is to examine the Arctic policy and strategy of Russia, perhaps the most difficult nation to understand in terms of Arctic security. The second goal of the article is to explain how the Arctic has become an issue of concern in Russia's relationship with China.

Adapted from mature and extensively utilized land-based munitions assessment techniques, a comprehensive suite of technologies are employed. Project phases and technologies include; diver reconnaissance utilizing former Navy EOD personnel, multi-beam sonar for bathymetry, side scan sonar for seafloor target detection and classification, sub-bottom profiling for sediment characterization, stationary scanning sonar to define high resolution bottom conditions, diver visual searches, full-coverage geophysical mapping via vessel-deployed magnetometer arrays, remote operated vehicle (ROV) deployments for visual and sonar searches and target interrogation, and ROVs equipped with an electromagnetic induction sensor array for target detection and interrogation. Additionally, three integrated underwater positioning systems were used to support accurate collection and integration of datasets within a comprehensive on-site GIS. Application of the methodology at two sites will be discussed. The first site in Seattle Washington comprised a highly cluttered environment around a working pier with water depths between 12 and 21 m. The second site comprises 1170 Ha at a former aerial bombing range at Choctawhatchee Bay near Pensacola, FL with water depths from 1 to 12 m with moderate currents.

Advancements in both coastal mapping data acquisition technology and data fusion techniques are executed through the Joint Airborne Lidar Bathymetry Technical Center of eXpertise. The Scanning Hydrographic Operational Airborne Lidar Survey system was initially designed in 1994 to produce bathymetric maps of the sea floor immediately surrounding federal navigation channels. The 2003 Compact Hydrographic Airborne Rapid Total Survey system integrated multiple topographic and bathymetric lidar sub-systems, an aerial camera, and a hyperspectral imager using a unique data fusion paradigm for use in regional coastal applications. The latest sensor development effort, the Coastal Zone Mapping and Imaging Lidar system, provides the next generation of coastal mapping technology through state-of-the-art lasers, receivers, scanners, and imagers. These advancements increase system performance over a wider range of water clarity conditions compared to existing coastal mapping technologies. Further, temporal and geometric problems in the data streams are eliminated by the simultaneous collection and sharing of a single navigation solution. The CZMIL effort bundles a multi-tiered software development effort concurrent with the hardware improvements. CZMIL will enable the production of both traditional and innovative value-added information products that address regional physical and environmental concerns. This paper provides an overview of CZMIL technology, its data processing environment and anticipated data products.

While 80 percent of Junior Officers serve in operational billets, only 20 percent of Senior Leaders serve in operational billets. Yet despite this operational talent requirement inversion, Army development efforts tend to focus disproportionately on building operational talent. Moreover, career progression through the rank of General Officer tends to excessively favor officers who have spent most of their career in operational billets. By opening additional opportunities for officers who serve outside of operational billets to reach senior leader ranks, and by exposing more officers to opportunities that develop non-operational talents, the Army can mitigate against talent gaps at senior ranks. This analysis employs discrete event simulation to quantify the extent to which attrition, promotion, and the dynamically changing need for two types of talent (operational and non-operational) impact the distribution of talent available across the Army's officer ranks.

We formulate the multi-observation visual recognition task as a joint sparse representation model and take advantage of the correlations among the multiple observations for classification using a novel joint dynamic sparsity prior. The proposed joint dynamic sparsity prior promotes shared joint sparsity pattern among the multiple sparse representation vectors at class-level, while allowing distinct sparsity patterns at atom-level within each class in order to facilitate a flexible representation. The proposed method can handle both homogenous as well as heterogenous data within the same framework. Extensive experiments on various visual classification tasks including face recognition and generic object classification demonstrate that the proposed method outperforms existing state-of-the-art methods.

In presence of such unknown degradations, the conventional approach first resorts to blind image restoration and then feeds the restored image into a classifier. Treating restoration and recognition separately, such a straightforward approach, however, suffers greatly from the defective output of the ill-posed blind image restoration. In this paper, we present a joint blind image restoration and recognition method based on the sparse representation prior to handle the challenging problem of face recognition from low-quality images, where the degradation model is realistic and totally unknown. The sparse representation prior states that the degraded input image, if correctly restored, will have a good sparse representation in terms of the training set, which indicates the identity of the test image. The proposed algorithm achieves simultaneous restoration and recognition by iteratively solving the blind image restoration in pursuit of the sparest representation for recognition. Based on such a sparse representation prior, we demonstrate that the image restoration task and the recognition task can benefit greatly from each other. Extensive experiments on face datasets under various degradations are carried out and the results of our joint model shows significant improvements over conventional methods of treating the two tasks independently.

Unlike existing work, we consider a trust metric considering both quality of service (QoS) trust and social trust for detecting malicious nodes. By statistically analyzing peer-to-peer trust evaluation results collected from sensor nodes, each cluster head applies trust-based intrusion detection to assess the trustworthiness and maliciousness of sensor nodes in its cluster. Cluster heads themselves are evaluated by the base station. We develop an analytical model based on stochastic Petri nets for performance evaluation of the proposed trust-based intrusion detection scheme, as well as a statistical method for calculating the false alarm probability. We analyze the sensitivity of false alarms with respect to the minimum trust threshold below which a node is considered malicious. Our results show that there exists an optimal trust threshold for minimizing false positives and false negatives. Further, the optimal trust threshold differs depending on the anticipated wireless sensor network lifetime.

Army Research Laboratory (ARL) and the U.S. Army Night Vision and Electronic Sensors Directorate (NVESD) have developed a terahertz-band imaging system performance model/tool for detection and identification of concealed weaponry. The details of the MATLAB-based model which accounts for the effects of all critical sensor and display components, and for the effects of atmospheric attenuation, concealment material attenuation, and active illumination, were reported on at the 2005 SPIE Europe Security & Defence Symposium (Brugge). An advanced version of the base model that accounts for both the dramatic impact that target and background orientation can have on target observability as related to specular and Lambertian reflections captured by an active-illumination-based imaging system, and for the impact of target and background thermal emission, was reported on at the 2007 SPIE Defense and Security Symposium (Orlando). This paper will provide a comprehensive review of an enhanced, user-friendly, Windows-executable, terahertz-band imaging system performance analysis and design tool that now includes additional features such as a MODTRAN-based atmospheric attenuation calculator and advanced system architecture configuration inputs that allow for straightforward performance analysis of active or passive systems based on scanning (single-or line-array detector element(s)) or staring (focal-plane-array detector elements) imaging architectures. This newly enhanced THz imaging system design tool is an extension of the advanced THz imaging system performance model that was developed under the Defense Advanced Research Project Agency's (DARPA) Terahertz Imaging Focal-Plane Technology (TIFT) program. This paper will also provide example system component (active-illumination source and detector) trade-study analyses using the new features of this user-friendly THz imaging system performance analysis and design tool.

However, as more capable robots have been developed and introduced to battlefield environments, the problem of interfacing with human controllers has proven to be challenging. Particularly in the field of military applications, controller requirements can be stringent and can range from size and power consumption, to durability and cost. Traditional operator control units (OCUs) tend to resemble laptop personal computers (PCs), as these devices are mobile and have ample computing power. However, laptop PCs are bulky and have greater power requirements. To approach this problem, a light weight, inexpensive controller was created based on a mobile phone running the Android operating system. It was designed to control an iRobot Packbot through the Army Research Laboratory (ARL) in-house Agile Computing Infrastructure (ACI). The hardware capabilities of the mobile phone, such as WiFi communications, touch screen interface, and the flexibility of the Android operating system, made it a compelling platform. The Android based OCU offers a more portable package and can be easily carried by a soldier along with normal gear requirements. In addition, the one hand operation of the Android OCU allows for the Soldier to keep an unoccupied hand for greater flexibility. To validate the Android OCU as a capable controller, experimental data was collected evaluating use of the controller and a traditional, tablet PC based OCU. Initial analysis suggests that the Android OCU performed positively in qualitative data collected from participants. C1 USA, Res Lab, Adelphi, MD 20783 USA.

These urban types of operations are referred to as MOUT (Military Operations on Urban Terrain). During urban operations, these UGV's encounter difficulties when opening doors. Current manipulator end effectors have these difficulties, because they are not designed to mimic human hand operations. This paper explains the mechanical nature of the Modular Universal Door Opening End-effector (MUDOE). MUDOE is a result of our development research to improve robotic manipulators ability to negotiate closed doors. The presented solution has the ability to mimic human hand characteristics when opening doors. The end-effector possesses an ability to maintain a high Degree of Freedom (DoF), and grasp the doorknob by applying equally distributed forces to all points of contact.

The need for learning incrementally, discarding prior data, is important because of the vast amount of data that can be generated by these sensors. This is crucial because the system needs to generate and update its internal models in real-time. There should be little difference between the training and execution phases; the system should be continually learning, or engaged in "life-long learning". This paper explores research into incremental learning systems such as nearest neighbor, Bayesian classifiers, and fuzzy c-means clustering.

Current literature on trust in multi-agent systems primarily deals with trust models and protocols of interaction in noncooperative scenarios. Here, we use cooperative game theory as the underlying mathematical framework to study the trust dynamics between agents as a result of their trust synergy and trust liability in cooperative coalitions.

This constant dependence on operator control introduces several problems, including a large cognitive load on the operator and a limited ability for the operator to maintain an appropriate level of situational awareness of his surroundings. One solution to reduce the dependence on teleoperation is to develop autonomous behaviors for the robot to reduce the strain on the operator. We consider mapping and navigation to be fundamental to the development of useful field autonomy for small unmanned ground vehicles (SUGVs). To this end, we have developed baseline autonomous capabilities for our SUGV platforms, making use of the open-source Robot Operating System (ROS) software from Willow Garage, Inc. Their implementations of mapping and navigation are drawn from the most successful published academic algorithms in robotics. In this paper, we describe how we bridged our previous work with the Packbot Explorer to incorporate a new processing payload, new sensors, and the ROS system configured to perform the high-level autonomy tasks of mapping and waypoint navigation. We document our most successful parameter selection for the ROS navigation software in an indoor environment and present results of a mapping experiment.

Previous studies have been performed to consistently discriminate between human and animal signatures using cadence analysis. The studies performed herein will expand upon this methodology by improving both the success rate of such methods as well as the effective range of classification. This is accomplished by fusing multiple seismic axes in real-time to separate impulsive events from environmental noise. Additionally, features can be extracted from the fused axes to gather more advanced information about the source of a seismic event. Compared to more basic cadence determination algorithms, the proposed method substantially improves the detection range and correct classification of humans and significantly decreases false classifications due to animals and ambient conditions.

In this paper, a multi-stage detection algorithm for stationary humans in infrared imagery is proposed. This algorithm first applies an efficient feature-based anomalies detection algorithm to search the entire input image, which is followed by an eigen-neural-based clutter rejecter that examines only the portions of the input image identified by the first algorithm, and culminates with a simple evidence integrator that combines the results from the two previous stages. The proposed algorithm was evaluated using a challenging set of infrared images, and the results support the usefulness of this multi-stage human detection architecture.

Despite the widespread use of greed in public dialog, relatively little attention has been directed toward studying this topic. In this chapter, we review the literature, develop a working definition, and develop a theoretically grounded conceptual model of perceptions of greed. Based on distributive justice and attribution theories, we suggest that greed is perceived when a person views 1 or more people as being responsible for seeking more than they deserve and need, while others are losing out. Theoretical and empirical implications of this model are discussed and we conclude that greed is an interesting and important construct that deserves greater research attention.

Traversal of a steep hill requires the vehicle to have sufficient momentum before entering the hill. This problem is part of a larger class of momentum-based motion planning problems such as the problem of lifting heavy objects with manipulators. Hence, solutions to the steep hill climbing problem have much wider applicability. The motion planning here is accomplished using a dynamic model of the skid-steered AGV used in the experiments along with Sampling Based Model Predictive Control (SBMPC), a recently developed input sampling planning algorithm that may be viewed as a generalization of LPA* to the direct use of kinodynamic models. The motion planning is demonstrated experimentally using two scenarios, one in which the robot starts at rest at the bottom of a hill and one in which the robot starts at rest a distance from the hill. The first scenario requires the AGV to first reverse direction so that the vehicle can gather enough momentum before reaching the hill. This corresponds to having the vehicle begin at a local minimum, which results in a problem that many traditional model predictive control methods cannot solve. It is seen that, whereas open loop trajectories can lead to vehicle immobilization, SBMPC successfully uses the information provided by the dynamic model to ensure that the AGV has the requisite momentum.

We propose two models: 1) the Afghan COIN social influence model, to represent how attitudes of local leaders are affected by repeated interactions with other local leaders, insurgents, and counterinsurgents, and 2) the nonlethal targeting model, a nonlinear programming (NLP) optimization formulation that identifies a strategy for assigning k US agents to produce the greatest arithmetic mean of the expected long-term attitude of the population. We demonstrate in an experiment the merits of the optimization model in nonlethal targeting, which performs significantly better than both doctrine-based and random methods of assignment in a large network.

As the most relevant results of an SOFC/GT performance analysis, the comparison of the load operation regime and the dependence of some crucial variables (such as power, SOFC temperature, and turbine shaft speed) on control variables are presented. The part-load operation and load transition are also analyzed to provide guidelines in developing safe and optimal load transition strategies.

The direction of arrival (DOA) was computed at each array and then the position of the source was estimated using algorithms based upon triangulation. Differential time delays between the microphones in a tetrahedral array were estimated in the frequency domain, and then DOA estimates were calculated using a weighted least squares approach. The location of the target was calculated by minimizing the weighted squared error of a cost function for different combinations of DOA estimates. The algorithms were tested offline using data collected by the U. S. Army Research Laboratory on an aircraft. The ground-truth position of the target was recorded using a GPS system as it maneuvered and compared to the results obtained from the localization algorithms. The algorithms performed well when estimating the x and y positions, but had difficulty obtaining consistently good z positions, or equivalently, height estimates.

This joint effort was led by ARL in partnership with other R&D centers and private industry. The primary goals were to detect hostile fire events (small arms, mortars, rockets, IEDs) and hostile human activities by providing solutions before, during, and after the events to improve sensor networking technologies; to develop multimodal sensor data fusion; and to determine effective dissemination techniques for the resultant actionable intelligence. Technologies included ultraviolet, infrared, retro-reflection, visible, glint, Laser Detection and Ranging (LADAR), radar, acoustic, seismic, E-field, magnetic, and narrow-band emission technologies; all were found to provide useful performance. The experiment demonstrated that combing data and information from diverse sensor modalities can significantly improve the accuracy of threat detections and the effectiveness of the threat response. It also demonstrated that dispersing sensors over a wide range of platforms (fixed site, ground vehicles, unmanned ground and aerial vehicles, aerostat, Soldier-worn) added flexibility and agility in tracking hostile actions. In all, the experiment demonstrated that multimodal fusion will improve hostile event responses, strike force efficiency, and force protection effectiveness.

During an impulsive seismic event, as the seismic wave components travel through a medium, the difference in their velocities results in a superimposed signal that will look drastically different at varying distances. It would be most beneficial to detect, classify and localize targets creating impulsive events if seismic sensor data could be reduced to a single wave type that has an expected shape and consistent features that do not change as a function of distance. Research was conducted to determine if measuring seismic data from within enclosures of specific architectural design could be used to attenuate specific wave types while maintaining energy of other wave types. The resulting waves produced by these geophone enclosures were then subject to testing using various algorithms to determine their ability to detect, classify, and localize seismic targets.

ID REPUTATION SYSTEMS; AUTOMATION; FRAMEWORK; PROTOCOLS; FUTURE; ROBUST AB Managing trust in a distributed Mobile Ad Hoc Network (MANET) is challenging when collaboration or cooperation is critical to achieving mission and system goals such as reliability, availability, scalability, and reconfigurability. In defining and managing trust in a military MANET, we must consider the interactions between the composite cognitive, social, information and communication networks, and take into account the severe resource constraints (e. g., computing power, energy, bandwidth, time), and dynamics (e. g., topology changes, node mobility, node failure, propagation channel conditions). We seek to combine the notions of "social trust" derived from social networks with "quality-of-service (QoS) trust" derived from information and communication networks to obtain a composite trust metric. We discuss the concepts and properties of trust and derive some unique characteristics of trust in MANETs, drawing upon social notions of trust. We provide a survey of trust management schemes developed for MANETs and discuss generally accepted classifications, potential attacks, performance metrics, and trust metrics in MANETs. Finally, we discuss future research areas on trust management in MANETs based on the concept of social and cognitive networks.

Jackson State University has a state-of-art HPHC cluster (an SRC-7), which contains traditional CPUs and reconfigurable processing units. The reconfigurable units are implemented using SRAM-based FPGAs. Currently, the off-the-shelf SRC-7 mechanism for incorporating user components (macros) does not directly support the common case of a multiple file VHDL hierarchy. This research explores a novel approach that allows multiple file VHDL floating-point kernels to be mapped onto the SRC-7. The approach facilitates the development of FPGA-based components via a hybrid technique that uses the SRC Carte compiler in conjunction with multiple file VHDL-based user macros. This research shows how Quartus Wizard-based VHDL floating-point components can be integrated into the Carte development environment.

The films were characterized via X-Ray diffraction and field emission scanning electron microscopy. The dielectric constant, loss tangent, tunability, and leakage current were measured as a function of electric field, frequency, and temperature. The film deposited with a lower precursor solution molarity solution had a larger permittivity and tunability, but it also had higher loss tangent and leakage current density. The internal stresses in the films are almost completely relaxed, and this is the main reason for the large, bulk-like dielectric constant in these films. C1 [Weiss, C. V.; Alpay, S.

A similar complex, identical except for the presence of ethyl groups at the 9-position of the fluorenes and tert-butyl groups at the 4- and 4'-positions of the bipyridine, was recently reported to possess a very high ratio of triplet excited-state absorption to ground-state absorption, a quantity that has long been used as a figure of merit for reverse saturable absorbers; in addition, femtosecond transient difference absorption experiments and picosecond open-aperture Z-scans have shown it to display broad nonlinear absorption throughout the visible spectrum. In this work, we measured the triplet excited-state absorption cross section at several representative wavelengths between 450 nanometers and 660 nanometers in an open-aperture top-hat Z-scan experiment employing a nanosecond-pulsed tunable optical parametric oscillator (OPO). The open-aperture Z-scan is a highly sensitive single-beam experiment used to measure nonlinear absorption. Since the spatial profile of the OPO beam resembled a cross-pattern, we closed an adjustable iris on the beam to create a top-hat profile. A dynamic five-level model was used to fit the Z-scan data.

McDonald, Mark P. Mahadevan, Sankaran TI A System of Systems Approach for Effects-Based Operational Planning Under Uncertainty SO MILITARY OPERATIONS RESEARCH LA English DT Article ID RELIABILITY; OPTIMIZATION; DESIGN AB Operational planning under uncertainty is often difficult because assessment of the impacts of these operations often requires a system of systems (SoS) level analysis to guide decision making. For example, one objective for military and support operations undertaken in Iraq and Afghanistan is to restore economic productivity in order to promote social order and stability. Yet, planning in this context is challenging due to the highly interdependent nature of the economic sectors. This paper develops a framework for decision support in effects-based operations (EBO) planning that integrates systems modeling, uncertainty analysis, and optimization. The proposed optimization under uncertainty (OUU) framework has three components that: 1) represent a network of interdependent systems using input-output models that describe the behavior of the various systems; 2) analyze and propagate uncertainties using analytical reliability methods; and 3) optimize SoS-level objectives under these uncertainties. Optimality conditions are derived for the proposed optimization formulation. A solution algorithm is presented and illustrated using numerical data representative of a predominantly oil-based national economy. C1 [McInvale, Howard D.] US Mil Acad, West Point, NY 10996 USA.

Depending on the exact measurement procedure, a given device stress tested under identical conditions may either pass or fail. The large variations observed in I(D)-V(GS) characteristics, and accompanying shift in threshold voltage (V(T)) and change in leakage current, are likely due to the complex time, temperature, and bias dependent nature of the charging and discharging of significant numbers of near-interfacial oxide traps (and possibly mitigated by the movement of mobile ions) which are not present in Si power devices. The variation in V(T) following a high temperature gate-bias (HTGB) stress is shown to be dependent on the measurement delay time, sweep direction, and temperature. Negative gate-bias temperature stress results show that device reliability may be limited due to increased drain leakage current in the OFF-state, which is caused by large shifts in V(T) depending on the gate-bias stress time, bias magnitude, and stress temperature. In addition, positive gate-bias stressing at elevated temperature may increase power dissipation in the ON-state.

The proposed architecture effectively reduces the capacitive loading at the input by utilizing a series connection of the filters, resulting in improvement in the return loss and stopband rejection for large arrays. This work demonstrates the feasibility of large-scale filter arrays without the need for additional costly isolation strategies for real-time spectrum monitoring applications.

Birds are unique in that they can synthesise ascorbic acid whereas humans and rodents lack this ability. Diagnostic tests that currently exist to measure ascorbic acid levels in birds are time-consuming and expensive. In the present study, a modified and improved reduction-based colorimetric assay was evaluated in turkeys, quail and chickens. The assay was rapid for quantifying ascorbic acid in plasma and tissue samples, and generated values consistent with those obtained using HPLC. Five breeds of heritage turkeys were studied, showing significant plasma AA differences among breeds and, within breeds, by sex. Quail displayed plasma AA levels similar to the corresponding values that were highest in turkeys, which again were significantly greater in males than females. Chicken plasma AA levels were comparable to the turkeys and quail. However, the spleens of chickens had AA levels more than 12-fold higher than plasma, which increased significantly with a 150 mg/kg AA feed supplement. These collective results show a broad utility for the modified AA assay, and demonstrate differences in birds by breed, sex and diet. C1 [Hardy, Chistopher G.] USN, Med Ctr, Portsmouth, VA 23708 USA.

TI The influence of soil parameters on the impulse and airblast overpressure loading above surface-laid and shallow-buried explosives SO SHOCK AND VIBRATION LA English DT Article AB The dynamic airblast, fragmentation, and soil ejecta loading environments produced by the detonation of surface-laid and shallow-buried mines are major threats to lightweight military vehicles. During the past several years, the US Army has focused considerable attention on developing improved methods for predicting the below-vehicle environment from these threats for use by vehicle/armor analysts; thereby, improving the survivability of these platforms. The US Army Engineer Research and Development Center recently completed the first year of a three-year effort to experimentally and numerically quantify the blast and fragment loading environments on vehicles due to surface and subsurface mine and IED detonations. As part of this research effort, a series of experiments was conducted to quantify the effects of soil parameters on the aboveground blast environments produced by the detonation of aboveground bottom-surface-tangent, buried top-surface-tangent, and shallow-buried 2.3-kg (5-lb) Composition C4 charges. The experiments were conducted using three different well characterized soils; 10.8% air-filled-voids (AFV) silty sand, 5.4% AFV clay, and 29.8% AFV poorly graded sand. The combined aboveground loads due to airblast and soil debris were measured by an impulse measurement device. The near-surface airblast overpressure was quantified by a series of side-on measurements above the charges at one elevation and three radial distances. This paper summarizes and compares the results of the experimental program with emphasis on defining the effect of soil parameters on the aboveground blast environment.

Facial recognition systems have the potential to identify suspicious individuals on law enforcement watchlists, but accuracy is severely hampered by the low resolution of typical surveillance footage and the far distance of suspects from the cameras. To improve accuracy, super-resolution can enhance suspect details by utilizing a sequence of low resolution frames from the surveillance footage to reconstruct a higher resolution image for input into the facial recognition system. This work measures the improvement of face recognition with super-resolution in a realistic surveillance scenario. Low resolution and super-resolved query sets are generated using a video database at different eye-to-eye distances corresponding to different distances of subjects from the camera. Performance of a face recognition algorithm using the super-resolved and baseline query sets was calculated by matching against galleries consisting of frontal mug shots. The results show that super-resolution improves performance significantly at the examined mid and close ranges. C1 [Hu, Shuowen; Maschal, Robert; Young, S. Susan] USA, Res Lab, Adelphi, MD 20905 USA.

The technique is integrated with the standard backprojection image formation algorithm to form SAR images with significant reduction in side lobes and noise. The key innovative concept in the IF-PC technique is the formation of many realizations of a SAR image of the same scene from many instances of randomized and reduced apertures. The IF-PC algorithm classifies each pixel in the SAR image into either target class (associated with physical objects) or noise class (noise, sidelobes) based on the statistics of the image pixel from many realizations of the SAR image. The IF-PC technique generates both types of resulting SAR imagery: amplitude and complex images that are almost noise-free. This paper demonstrates the results using both simulation and real radar data from the U. S. Army Research Laboratory's (ARL) low-frequency SAR radar in forward-looking mode.

We utilize the characteristic bipedal motion to recognize and track humans and vehicles. We characterize the moving objects based on its unpredictability and attempt to identify the class. We extract the velocity of the moving human and separate it from the micro-Doppler of the human motion in order to improve the speed of the velocity measurement and thus the extracted acceleration. We describe the detection, tracking, and characterization of moving objects like people and vehicles, as well as the radar sensors used for the measurements, and detail the velocity extraction at millisecond speeds. We discuss the robustness of the approach and potential improvements. C1 [Tahmoush, Dave; Silvious, Jerry] USA, Res Lab, Antennas & RF Technol Integrat Branch, Adelphi, MD 20783 USA.

A time-integrated range-Doppler map is a compilation of range-Doppler maps over time that results in a spectrogram-like characterization of Doppler while maintaining the range information as well. These are compiled from the range-Doppler maps by taking the maximum value for each pixel over a time range. The time resolution is overlapped onto the range resolution, which is in effect a rotation of the traditional spectrogram which compresses range. This type of radar imaging also allows multiple subjects to be viewed simultaneously and avoids tracking issues in spectrogram creation.

However, even with all the material advances made to date, there is no guarantee that this technology will be mature enough to meet the stringent FPA specifications required for long wavelength infrared (LWIR) systems. With this in mind, the Army Research Laboratory (ARL) has begun investigating HgCdSe material for infrared (IR) applications. Analogous to HgCdTe, HgCdSe is a tunable semiconductor that can detect any wavelength of IR radiation through control of the alloy composition. In addition, several mature, large area bulk III-V substrates are nearly lattice-matched to HgCdSe giving this system a possible advantage over HgCdTe in which no scalable, bulk substrate technology exists. We have initiated a study of the growth of HgCdSe using molecular beam epitaxy (MBE). Growth temperature and material flux ratios were varied to ascertain the best growth conditions and study defect formation. Smooth surface morphology has been achieved using a growth temperature much lower than HgCdTe. Preliminary data suggest a linear relationship between the Se/Cd flux ratio used during growth and the cut-off wavelength as measured by FTIR.

A close to optimal growth window has been established for MBE growth of ZnTe(211)/Si(211) to achieve high crystalline quality, low defect and dislocation densities as well as excellent surface morphology. Using this baseline MBE growth process, we are able to obtain ZnTe(211)/Si wafers with X-ray full-width at half-maximum (FWHM) as low as 70 arcsec, low dislocation density (similar to 10(5) cm(-2)) and defect density (1000 cm(-2)).

Improved epitaxial growth conditions have yielded improvements in material quality over the past several years. However, surface instability resulting in electrical shunt pathways across the junction, and diminished device performance over time is still a major limiting factor for application of InAs/GaSb SL in long-wavelength infrared detectors. This study focuses on a two-step approach towards the successful surface passivation of long-wavelength InAs/GaSb superlattice structures. Two distinct sulfide chemical surface treatments were applied to inhibit the formation of native surface oxides and satisfy dangling bonds. This was followed by the application of a robust SU8-2 dielectric treatment on the mesa sidewalls to inhibit sulfide layer degradation and oxidation of the surface over time. A variable area diode analysis (VADA) technique employing diodes of variable diameter (40-400um) enabled the investigation of surface resistivity as a result of different passivation treatments. Temperature dependent studies of the dark current were used to understand the dominating current mechanisms. C1 [DeCuir, Eric. A., Jr.; Little, John. W.] USA, Res Lab, Adelphi, MD USA.

However, one disadvantage of the detector is the relatively low operating temperature needed to suppress the dark current. By coating two additional layers (thin insulator and high critical temperature (Tc) superconductor) on the top contact layer of a C-QWIP wafer, the top three layers of the detector form a high-Tc superconducting single electron tunneling junction. It could act as an electron filter because of the presence of an energy gap in superconductors. For QWIPs, the photo electrons and dark electrons are well separated in energy, most dark current is conducting below the quantum well (QW) barrier height and most photo current is conducting above the barrier height. Most dark electrons thus could be blocked by the junction while most photo electrons pass the junction by applying an appropriate voltage. Therefore, both the sensitivity and the operating temperature of the detector could be improved. Our calculation shows that the filter could provide 40% or 70% improvement in Noise Equivalent Temperature Difference (NETD) of detector focal plane arrays (FPAs) at normal operating temperature, depending on whether the detector emitter photocurrent to dark current ratio is = 1 (Emitter is background limited BLIP) or = 0.1 (Emitter is far from BLIP). For both cases, the filter could increase the detector FPAs operating temperatures up to 90K (30K improvement) with 15% to 25% NETD improvement respectively. C1 [Sun, Jason; Choi, K.

A Prospective Pilot Study to Identify the Prevalence of OSA in Patients with Difficult Mask Ventilation Under General Anesthesia SO JOURNAL OF CLINICAL SLEEP MEDICINE LA English DT Article DE Obstructive sleep apnea; difficult mask ventilation ID RISK-FACTOR; HYPERTENSION; QUESTIONNAIRE; INTUBATION; HEALTH AB Background: Given the pathogenesis of obstructive sleep apnea (OSA), anesthesiologists may be in a unique position to rapidly identify patients who are at risk for undiagnosed OSA in the perioperative period. Identification is the first step in prompt diagnosis and potential prevention of OSA related comorbidities. Patients who exhibit unanticipated difficult mask ventilation (DMV) during induction of general anesthesia may be at risk of having undiagnosed OSA. Objective: To determine the association of OSA in patients with difficult mask ventilation under general anesthesia. Methods: Ten patients were identified over a 2-year period at the time of anesthetic induction as being difficult to mask ventilate and were then enrolled in this prospective pilot study. After enrollment and informed consent, the patients were referred to the sleep study center for full overnight polysomnography to evaluate for the presence and severity of OSA. Results: Of our cohort, 9/10 patients exhibited polysomnographic evidence of OSA, while the last subject tested positive for sleep disordered breathing. Eighty percent (8/10) of subjects espoused snoring, but only 10% (1/10) reported witnessed apneas. Average DMV was 2.5, and higher grades of DMV were associated with more severe OSA. Conclusion: In this study, difficult mask ventilation was predictive of undiagnosed OSA. Anesthesiologists may be in a unique position to identify patients at risk for OSA and prevention of related comorbidities.

We study plasmonic resonances in large format (similar to 1 mm(2) area) arrays, consisting of electron beam-patterned horizontal (e.g., parallel to the substrate) Ag lines patterned on ultrathin (< 20 nm) tunneling barriers (NiO, NbOx, and other oxides). Our e-beam fabrication technique is scalable to large dimensions, and allows us to easily probe different antenna dimensions. These tunneling barriers, located on a metallic ground plane, rectify the alternating current generated in the nanoantenna at resonance. We measure the plasmonic resonances in these nanoantennas, and find good agreement with modeling, which also predicts that the electric field driving the electrons into the ground plane (and therefore the rectification efficiency) is considerably enhanced at resonance. Various metal-insulator-metal tunneling diodes, incorporating the afore-mentioned barrier layers and different metals for the ground plane, are experimentally characterized and compared to our conduction model. We observe similar to 1 mV signals from NiO-based nanorectenna arrays illuminated by 532 nm and 1064 nm laser pulses, and discuss the origin of these signals.

Hurricane Bill (H-s = 3+ m, T-p = 18 s) was a long-period wave event with strong evidence of non-linear wave transformations, and a track that was offshore such that the coast received very little wind. A strong depth-uniform longshore current was observed at the 5 and 6 m sites (up to 1.8 m/s) that was in-phase with the wave energy. Weak currents were measured at the 8 and 11 m depth sites, indicating that the limit of the surf zone extended to between 6 and 8 m depth. Hurricane/Nor'easter Ida (H-s = 5+ m, T-p = 12 s) was a typical large wave event in the fall, with strong winds (wind-sea a major wave component) and rotating wind direction. Hurricane Earl (H-s = 4+ m, T-p = 15 s) was the first major wave event with all sensors in place, since the sensors at the 2 and 3 m depths were added in August 2010. For the selected events we present the observations of wave evolution across the surf zone. The offshore extent of wave breaking was determined from Argus Station imagery by analyzing pixel intensity for time exposure images along cross-shore transect. Surf zone widths are compared to the estimated extent of breaking by comparing wave energy across the array and the magnitude of the longshore current. The alongshore momentum balance was estimated to determine the contribution of radiation stress gradients to observed longshore current.

Direct alcohol, alkaline fuel cells suffer from a rapid decrease in cell potential at low discharge currents. Several effects are described to account for this drop in cell potential. Quaternary ammonium ions can specifically adsorb on the catalyst surface decreasing the active surface area and lowering the rate of methanol oxidation. In addition, the tethering of the quaternary ammonium cations on the polymer electrolyte inhibits the cation mobility causing a diffuse double layer to be formed. The diffuse double layer electrostatically inhibits the migration of hydroxide to the surface of the electrode which is needed for alcohol oxidation. (C) 2011 The Electrochemical Society.

Given this interest, it is desirable to be able to describe accurately the combustion mechanism and kinetics of HN3, the smallest, high-nitrogen compound. We report a combined experimental and modeling study of neat and HN3-doped H-2/O-2/Ar flames. We employed thin-wire thermometry and hydroxyl (OH) laser-induced fluorescence (LIF) to measure the flame temperatures and molecular beam-mass spectrometry, LIF, or both, to measure the species concentrations. We assembled a detailed chemical mechanism containing 24 species and over 100 reactions and tested it by comparing our experimental profiles HN3, H-2, O-2, H2O, N-2, NO, NH, and OH to those predicted by the PREMIX flame code. Our model predicts well the species profiles, except for HN3 and NO. Rate and sensitivity analyses reveal that the HN3 + OH = N-3 + H2O reaction is important in HN3 consumption and NO production, and we provide a revised rate expression for this reaction that is consistent with our experimental results.

Fuel economy is typically selected as a calibration objective at part-load operating conditions. However, to secure vehicle driveability and smooth engine operation with low vibration and harshness, the combustion variability is considered by introducing the coefficient of variation in the indicated mean effective pressure characterized through a statistical analysis of experimental data. Other engine responses are fully predicted through a co-simulation approach by implementing the quasi-dimensional combustion simulation into the one-dimensional gas exchange simulation, and subsequently captured by an artificial neural network for fast computation. The best actuator set points are determined by solving the constrained multiple-objective optimization problem with fuel economy and combustion variability objectives under part-load conditions. The calibration eliminates a high combustion variability at low loads and low speeds, maintaining most of the fuel economy benefit achievable with variable valve timing, and it can be used for an implementable feedforward control strategy.

For off-road performance, predictions are based on rough terrain ride comfort, which is described using a parameter entitled root-mean-square (RMS) surface roughness. Likewise, on-road vehicle performance depends heavily on the slopes of the individual road segments. Traditional methods of computing RMS and road slope values call for high-resolution (inch-scale) surface elevation data. At this scale, surface elevation data is both difficult and time consuming to collect. Nevertheless, a current need exists to attribute large geographic areas with RMS and road slope values in order to better support vehicle mobility predictions, and high-resolution surface data is neither available nor collectible for many of these regions. On the other hand, meter scale data can be quickly and easily collected for these areas using unmanned aerial vehicle (UAV) based IFSAR and LIDAR sensors. A statistical technique for inferring RMS values for large areas using a combination of fractal dimension and spectral analysis of five-meter elevation data is presented. Validation of the RMS prediction technique was based on 43 vehicle ride courses with 30-centimeter surface elevation data. Also presented is a model for classifying road slopes for long road sections using five-meter elevation data. The road slope model was validated against one-meter LIDAR surface elevation profiles. These inference algorithms have been successfully implemented for regions of northern Afghanistan, and some initial results are presented.

However, some potential mines can be false alarms due to the similarity of the mine signatures with natural and other manmade clutter signatures. Therefore, in addition to the target features, spatial distribution of the detected targets can be used to improve the minefield detection performance. In our recently published SPIE paper, we evaluated minefield detection performance for both patterned and unpatterned minefields in highly cluttered environments, simultaneously using both target features and target spatial distributions that define Markov Marked Point Process (MMPP). The results have suggested that proper exploitation of spectral/shape features and spatial distributions can indeed contribute improved performance of patterned and unpatterned minefield detection. Also, the ability of the algorithm to detect the minefields in highly cluttered environments shows the robustness of the developed minefield detection algorithm based on MMPP formulation. Moreover, the results show that the MMPP minefield detection algorithm performs significantly better than the baseline algorithm employing spatial point process with false alarm mitigation. Since these results were based on the simulated data, it is not clear that the MMPP detection algorithm has fully achieved its best performance. To validate its performance, an analytical solution for the minefield detection problem will be developed, and its performance will be compared with the performance of the simulated solution. The analytical solution for the complete minefield detection problem is intractable due to a large number of detections and the variation of the number of detected mines in the minefield process. Therefore, an analytical solution for a simplified detection problem will be derived, and its minefield performance will be compared with the minefield performance obtained from the simulation in the same MMPP framework for different clutter rates.

The primary objective of this first phase is to demonstrate, via laboratory experiments, the capabilities of a breadboard laser system to "drill" through a minimum depth of 15 cm of earthen materials to defeat a buried mine at a standoff distance greater than 20 m. In the initial phase covered by this report, results of short range laboratory testing by 3 contractors are reported. The planned second phase of this program will consist of procuring a more capable 10 kW SM laser and performing field-testing at longer standoff ranges.

Variations in these terms are often blamed for poor agreement between model predictions and measured MRTD. By averaging over repeated human measurements, and carefully recording all system parameters affecting image quality, it should be possible to make an accurate prediction of MRTD performance for any resolvable frequency. Utilizing the latest NVESD performance models with updates for noise, apparent target angle, and human vision, predicted MRT are compared with measured curves.

S. Army imaging system target acquisition model, based on the targeting task performance metric. The model is characterized by the resolution and sensitivity of the sensor as well as the contrast and task difficulty of the target set. The contrast of the target is defined as a spatial average contrast. The model treats the contrast of the target set as spatially white, or constant, over the band-limit of the sensor. Previous experiments have shown that this assumption is valid under normal conditions and typical target sets. However, outside of these conditions, the treatment of target signature can become the limiting factor affecting model performance accuracy. This paper examines target signature more carefully. The spatial frequency dependence of the standard U. S. Army RDECOM CERDEC Night Vision 12 and 8 tracked vehicle target sets is described. The results of human perception experiments are modeled and evaluated using both frequency dependent and independent target signature definitions. Finally the function of task difficulty and its relationship to a target set is discussed. C1 [Du Bosq, Todd; Olson, Jeffrey] USA, RDECOM CERDEC NVESD, Ft Belvoir, VA 22060 USA.

This problem has been solved analytically. In this paper we describe the analytical solution and provide derivations of the results. Comparison with perception experiments will be reported in a future publication and hopefully will support the results presented here. The provided solution is applicable to any scenario where the search parameters are changing with time and are specified. In particular, the solution can be used to estimate the probability of target acquisition as a function of time: (1) when the sensor-target range is changing, (2) for a slewed sensor where the target is alternately in and out of the field of view, and (3) for a sensor that switches between wide and narrow fields of view.

Each sensor is characterized by individual search parameters (P-infinity, tau) which are different either because the sensors are at different ranges or are different because the sensors are at the same range but have different properties. The target is said to be detected when the first observer detects the target. Using this definition for time to detect, we derive an analytical expression for the mean detection time. 2) If multiple observers independently search an image obtained from a single sensor how does the mean time until the first observer detects the target vary with the number of observers. 3) If multiple observers independently search an image obtained from a single sensor how does the probability of detection vary with the number of observers. Here the target is said to be detected if any of the observers detect the target. 4) For the problem of two stationary observers searching independently for a stationary target we found the probability density function for the time to detect.

A Vertical Cavity Surface-Emitting Laser (VCSEL) array was designed and implemented with spectral filtering to effectively remove self-luminosity and the fireball from the image, providing excellent background discrimination in a variety of range test scenarios. Further improvements to the system are proposed for applications such as imaging through murky water or dust clouds with optimal penetration of obscurants.

This is especially true of reflective-band sensors operating in low-light conditions. To accurately predict target acquisition range performance, image degradation introduced by the sensor must be properly combined with the limitations of the human visual system. This is modeled by adding system noise and blur to the contrast threshold function (CTF) of the human visual system, creating a combined system CTF. Current U. S. Army sensor performance models (NVThermIP, SSCAMIP, IICAM, and IINVD) do not properly address how external noise is added to the CTF as a function of display luminance. Historically, the noise calibration constant was fit from data using image intensifiers operating at low display luminance, typically much less than one foot-Lambert. However, noise calibration experiments with thermal imagery used a higher display luminance, on the order of ten foot-Lamberts, resulting in a larger noise calibration constant. To address this discrepancy, hundreds of CTF measurements were taken as a function of display luminance, apparent target angle, frame rate, noise intensity and filter shape. The experimental results show that the noise calibration constant varies as a function of display luminance. To account for this luminance dependence, a photon shot noise term representing an additional limitation in the performance of the human visual system is added to the observer model. The new noise model will be incorporated in the new U. S. Army Integrated Performance Model (NV-IPM), allowing accurate comparisons over a wide variety of sensor modalities and display luminance levels.

Currently the Army's imager performance model, the Targeting Task Performance (TTP) metric uses a parameterized model, based upon a fit to a number of perception experiments, called MTF squeeze. MTF squeeze applies an additional degradation to the TTP metric based upon the amount of spurious response in the final image. While this approach achieves satisfactory results for the data sets available, it is not clear that these results extend to a wider variety of operating conditions. Other models treat the artifacts arising from spurious response as a target-dependent noise. Modeling spurious response as noise allows proper treatment of sampling artifacts across a wider variety of systems and post-processing techniques. Perception experiments are used to assess the performance of both the MTF squeeze and aliasing as noise methods. The results demonstrate that modeling all of the aliased frequencies as a target-dependent noise leads to erroneous predictions; however, considering only aliased signals above the Nyquist rate as additive noise agrees with experimental observations.

We found that for a 24 x 24 x 1.5 mu m(3) cross-grating QWIP, the QE is peaked at 13.0, 11.0, and 8.4 mu m, insensitive to the grating periods. These peaks are identified as the first three harmonic resonances associated with the pixel resonant cavity. For a regular prism-shaped corrugated QWIP (C-QWIPs) with a 25-mu m pitch, the QE oscillates about its classical value of 24.5% within the calculated wavelength range from 3 to 15 mu m. A peaked value of 32% occurs at 9.1 mu m. For pyramidal C-QWIPs, the maximum QE is 42%, and for cone-shaped C-QWIPs, it is 35%. In the presence of an anti-reflection coating, the oscillation amplitude diminishes, and the average values generally rise to near the peaks of the oscillations. The modeling results are compared with the experimental data for grating QWIP focal plane arrays (FPAs) and prism-shaped C-QWIP FPAs; satisfactory agreements were achieved for both. After verifying our EM approach, we explored other detector geometries and found new types of resonator QWIPs (R-QWIPs) that can provide 30% QE at certain wavelengths on a 1.5-mu m-thick active material. Combining the high QE of a resonator and the high gain of a thin material layer, the new R-QWIPs will have a conversion efficiency far higher than the existing QWIP detectors. The present resonator approach will also have an impact on other detector technologies. C1 [Choi, K. K.; Sun, J.] USA, Res Lab, Adelphi, MD 20783 USA.

The purpose of the investigations is to identify the dominant carrier recombination mechanisms and in particular to determine at what temperature and voltage is the onset of Shockley Read Hall (SRH) space charge currents. The important finding is that the currents can mostly be explained by a combination of Auger (e-e) and radiative carrier recombination processes with no evidence of SRH recombination through near mid-gap states; a lower bound estimate of the SRH lifetime for LWIR photodiode is 100 mu s. Intrinsic radiative recombination is found to be the dominant carrier recombination mechanisms for the MWIR photodiode with a carrier concentration N-d = 10(15) cm(-3), and Auger (e-e) being dominant for the LWIR photodiode. The LWIR Auger (e-e) lifetime data is well fitted with the Beattie, Landsberg and Blakemore (BLB) formulas with a constant overlap integral |F1F2| = 0.15, which is in accord with recent electronic band structure calculations. From the analysis of variable area LWIR photodiodes the minority carrier conductivity mobility and diffusion length at 80K are calculated to be 350 cm(2)/V-s and 23 mu m respectively. The LWIR lifetime measured by the photoconductive decay method is in agreement with the expected intrinsic Auger (e-e) lifetime approximate to 2 mu s at 80K and with the lifetimes obtained from device analysis. For T <= 40K, trap assisted tunneling is the dominant current in reversed bias LWIR photodiodes; forward bias currents are dominated by diffusion currents of origin in the n-layer. For the MWIR photodiode deviation from diffusion limited behavior to G-R is observed at T < 80K and, the SRH lifetimes tau(n0) and tau(p0) are estimated to be 50 ms. Measured and calculated external quantum efficiencies at the peak responsivity wavelength lambda(pk) for both MWIR and LWIR photodiodes are approximate to 70% at 78K. For imaging in the 3-5 mu m spectral band scene temperature 300K, F/3 optics, the noise equivalent temperature difference NE Delta T of MWIR photodiodes is calculated to be near background limited performance BLIP = 12.4 mK for detector temperatures T-d <= 150K.

The narrow field of view images the SWIR radiation at a slow f/number of 10.0, while the wide field of view images the MWIR radiation at f/1.9. The field of view is changed via a single lens that changes its axial position within the lens, resulting in an axial zoom and an overall magnification change of 6X. The change in focal length and f/number at the same time enables an increased focal length without having to increase the aperture size by the ratio of the focal length change. The large field of view change is achieved by both the motion of the lens, and the use of the spectral properties of the materials that change with wavelength. The change in spectral bands is accomplished via the use of a spectral filter wheel.

Devastating maxillofacial injuries challenged the surgical professions to provide form and function to the defects inflicted by penetrating trauma on the battlefield. Local, regional, and distant flap transfers were developed to treat maxillofacial battle injuries in WWI and while still valued procedures, multiple surgical steps, donor site morbidity and limited esthetic-functional outcomes are often the result. During the 1980s, the advent of microsurgery added an invaluable tool to the reconstructive surgeons' armamentarium. However, despite significant technical advances, the results following major traumatic war injuries are less than satisfactory, both esthetically and functionally. Facial allotransplantation may offer an invaluable alternative to traditional reconstructive options. C1 USA, Inst Surg Res, San Antonio, TX USA.

Electronic beam steering eliminates the need for complex mechanical scanners that are commonly implemented with millimeter-wave imaging systems and would reduce overall system size and weight. We present a concept study of a 220 GHz reflection-type phased array for the purpose of performing beam scanning of a confocal reflector system. Requirements for effective imaging of the desired target region are established, including spatial resolution, total scan angle, and number of image pixels achievable. We examine the effects of array architecture on beam characteristics as it is scanned off broadside, including Gaussicity and encircled energy. Benchmark requirements are determined and compared with the capabilities of several potential phase shifter technologies, including MEMS-based variable capacitor phase shifters, switches, and varactor diode-based phase shifters.

These surprising nonlinear systems generate random, aperiodic waveforms that offer an exact analytic representation, allowing the implementation of simple matched filters and coherent reception. Notably, this approach enables nearly optimal detection of noise-like waveforms without need for expensive variable delay lines to store wideband waveforms for correlation. Mathematically, the waveform is expressed as a linear convolution of a bit sequence with a fixed basis function. We realize a simple matched filter for the waveform using a linear filter whose impulse response function is the time reverse of the basis function. Importantly, linear filters matched to finite bit sequences can be defined, enabling pulse compression and spread spectrum radar. We present an example oscillator, its matched filter, and simulation results demonstrating the pulse compression radar concept.

S. Army Research Laboratory (ARL) has been investigating the utility of ultra-wideband (UWB) synthetic aperture radar (SAR) technology for detecting concealed targets in various applications. We have designed and built a vehicle-based, low-frequency UWB SAR radar for proof-of-concept demonstration in detecting obstacles for autonomous navigation, detecting concealed targets (mines, etc.), and mapping internal building structures to locate enemy activity. Although the low-frequency UWB radar technology offers valuable information to complement other technologies due to its penetration capability, it is very difficult to comprehend the radar imagery and correlate the detection list from the radar with the objects in the real world. Using augmented reality (AR) technology, we can superimpose the information from the radar onto the video image of the real world in real-time. Using this, Soldiers would view the environment and the superimposed graphics (SAR imagery, detection locations, digital map, etc.) via a standard display or a head-mounted display. The superimposed information would be constantly changed and adjusted for every perspective and movement of the user. ARL has been collaborating with ITT Industries to implement an AR system that integrates the video data captured from the real world and the information from the UWB radar. ARL conducted an experiment and demonstrated the real-time geo-registration of the two independent data streams. The integration of the AR sub-system into the radar system is underway. This paper presents the integration of the AR and SAR systems. It shows results that include the real-time embedding of the SAR imagery and other information into the video data stream.

Such reflections arise because radio frequency components are rarely impedance-matched over an ultra-wide bandwidth. Any mismatch between components causes a portion of the impulse to reflect within the radar front-end. If the reflection couples into the transmit antenna, the radar emits an unintended, delayed and distorted replica of the intended radar transmission. These undesired transmissions reflect from the radar environment, produce echoes in the radar image, and generate false alarms in the vicinity of actual targets. The proposed solution for eliminating these echoes, without redesigning the transmit antenna, is to dissipate pulse reflections in a matched load before they are emitted. A high-speed switch directs the desired pulse to the antenna and redirects the undesired reflection from the antenna to a matched load. The Synchronous Impulse Reconstruction (SIRE) radar developed by the Army Research Laboratory (ARL) is the case-study. This paper reviews the current front-end design, provides a recent radar image which displays the aforementioned echoes, and describes the switch-cable-load circuit solution for eliminating the echoes. The consequences of inserting each portion of the new hardware into the radar front-end are explained.

At these standoff ranges, received wavefronts impinging on a linear array can be considered planar, enabling implementation of a variety of phase-based beam-forming techniques. At near ranges, however, the plane-wave assumption no longer holds. We describe enhancements to an impulse-based, low-frequency, ultra-wideband, moving-target imaging system for near-range, through-the-wall MTI. All MTI image processing is performed in the time domain using a change detection (CD) paradigm. We discuss how MTI image quality can be increased through the introduction of randomized linear arrays. After describing the process in detail, we present results obtained using data collected by an impulse-based, low frequency, ultra-wideband system.

S. Army Research Laboratory (ARL) designed and fabricated the Synchronous Impulse REconstruction (SIRE) radar system in an effort to address fundamental questions about the utilization of low frequency, ultrawideband (UWB) radar. The SIRE system includes a receive array comprising 16 receive channels, and it is capable of operating in either a forward-looking or a side-looking mode. When operated in side-looking mode, it is capable of producing high-resolution Synthetic Aperture Radar (SAR) data. The SAR imaging algorithms, however, initially operated under the assumption that the vehicle followed a nearly linear trajectory throughout the data collection. Under this assumption, the introduction of vehicle path nonlinearities distorted the processed SAR imagery. In an effort to mitigate these effects, we first incorporated segmentation routines to eliminate highly non-linear portions of the path. We then enhanced the image formation algorithm, enabling it to process data collected from a non-linear vehicle trajectory. We describe the incorporated segmentation approaches and compare the imagery created before and after their incorporation. Next, we describe the modified image formation algorithm and present examples of output imagery produced by it. Finally, we compare imagery produced by the initial segmentation algorithm to imagery produced by the modified image-formation algorithm, highlighting the effects of segmentation parameter variation on the final SAR image.

A time-integrated range-Doppler map is a compilation of range-Doppler maps over time that results in a spectrogram-like characterization of Doppler while maintaining the range information as well. These are compiled from the range-Doppler maps by taking the maximum value for each pixel over a time range. The time resolution is overlapped onto the range resolution, which is in effect a rotation of the traditional spectrogram which compresses range. This type of radar imaging also allows multiple subjects to be viewed simultaneously and avoids tracking issues in spectrogram creation. The display of range-Doppler movies or spectrograms with range extent is also demonstrated. C1 [Tahmoush, Dave; Silviousa, Jerry] USA, Res Lab, Adelphi, MD 20783 USA.

These can be used to visually identify both the target type as well as the target activity. We model and measure some of the micro-Doppler motions that are amenable to polarimetric measurement. Understanding the capabilities and limitations of radar systems that utilize micro-Doppler to measure human characteristics is important for improving the effectiveness of these systems at securing areas. In security applications one would like to observe humans unobtrusively and without privacy issues, which make radar an effective approach. In this paper we focus on the characteristics of radar systems designed for the estimation of human motion for the determination of whether someone is loaded. Radar can be used to measure the direction, distance, and radial velocity of a walking person as a function of time. Detailed radar processing can reveal more characteristics of the walking human. The parts of the human body do not move with constant radial velocity; the small micro-Doppler signatures are time-varying and therefore analysis techniques can be used to obtain more characteristics. Looking for modulations of the radar return from arms, legs, and even body sway are being assessed by researchers. We analyze these techniques and focus on the improved performance that fully polarimetric radar techniques can add. We perform simulations and fully polarimetric measurements of the varying micro-Doppler signatures of humans as a function of elevation angle and azimuthal angle in order to try to optimize this type of system for the detection of arm motion, especially for the determination of whether someone is carrying something in their arms. The arm is often bent at the elbow, providing a surface similar to a dihedral. This is distinct from the more planar surfaces of the body and allows us to separate the signals from the arm (and knee) motion from the rest of the body. The double-bounce can be measured in polarimetric radar data by measuring the phase difference between HH and VV. Additionally, the cross-pol and co-pol Doppler signatures are analyzed, showing that the HH polarization may perform better on dismounts in open grass.

The use of negative refractive index materials is discussed in reference to the original concept of the perfect lens, leading to the Rotman lens and the Luneburg lens. In Rotman lens, negative refractions help reducing the lens size and a broadband electromagnetic band gap (EBG) surface is used to prevent reflections off the sidewalls. Verification of negative refraction and simulation of isotropic material performance are presented, as well as an example of broadening the band of an EBG surface.

When the people are walking, sensors observe the signals for a longer period compared to the case in which people are jogging. To identify fast-moving people, one must make the decision based on the few telltale signals generated by a person jogging: a higher impact of a foot on the ground, which can be monitored by seismic sensors; the panting noise observed through an acoustic sensor; or a higher Doppler from an ultrasonic sensor, to name few. First, we investigate the phenomenology associated with seismic signals generated by a person walking and jogging. Then, we analyze ultrasonic signatures to distinguish the characteristics associated with them. Finally, we develop the algorithms to detect and classify people walking and jogging. These algorithms are tested on data collected in an outdoor environment. C1 [Damarla, Thyagaraju; Sabatier, James] USA, Res Lab, Adelphi, MD 20783 USA.

The method is applied to data recorded from a Scanning Laser Doppler Vibrometer, and likewise to numerical studies from a plane strain finite element model. A filtering procedure is implemented, and the reflected, converted, and transmitted waves are separated in the frequency/wavenumber domain, and then integrated spatially in the space/frequency domain. An accurate experimental technique for capturing the multiple components from a single laser head is verified. Based on an initial in-plane excitation, the spatially-integrated multiple component mode conversion coefficients are shown to mitigate experimental noise compared to single component mode conversion coefficients.

The tunable filter development is intended to cover spectral regions from the visible to the longwave infrared by developing a number of different filters each operating over a different wavelength region. The main objective of developing such miniature tunable filters is to use each in a miniature hyperspectral imager by placing it in front of a commercial focal plane array with a suitable optical train. Such a miniature tunable device has many more applications, i.e., in developing tunable sources. Recently, we succeeded in fabricating some operational FP filters operating in the visible/near infrared (VIS/NIR) wavelength region from 400 to 800 nm. The filter design uses one fixed mirror and the second mirror moves using an electrostatic force. The device with a dimension of 18x24 mm(2) is composed of two parts: one fixed Ag mirror and one electrostatically moveable Ag mirror. Commercially available thin quartz wafer with low total thickness variation (TTV) was used as the substrate for each of these two parts. Au bumps were deposited in both parts in order to control the initial air gap distance and Au-Au bonding was used to bond two parts together. This paper will describe the device design considerations, the fabrication process, the effect of electrostatic force, the optical spectral measurements, and present test results.

This hinders sample preparation for systems biology analysis. Sample heterogeneity caused by non-synchronized development, intrinsic variation in structure, and spurious germination triggered by handling all increase the complexity of sample content, which complicates detailed molecular characterization of spores. Mass spectrometry of spores is further constrained by requirements for sample pre-treatment due to the problematic nature of their crosslinked layers and abundant ionic content. Finally, safety is a principal concern in handling pathogenic specimens such as Bacillus anthracis, which requires dependable means for complete decontamination before transfer and analysis outside of a biocontainment environment. Traditional methods of spore inactivation are necessarily harsh and typically render sample material unsuitable for detailed spectral analysis. This chapter summarizes the variety and complexity of spores as sample material for study, reviews methods of spore decontamination and lysis, and then introduces two recently developed approaches to extract spore proteins for mass spectral analysis. One method employs ultra-high pressure cycling to achieve complete inactivation with extraction in a single tube, useful for whole analysis of the spore proteome. The other employs focused microwave energy to create exposure-controlled partial extracts of spore components as a probe of variations in averaged spore structure between preparation lots. Both methods are shown to decontaminate B. anthracis specimens while leaving proteins intact for mass spectrometry, including measurement of biomolecular markers intended for qualitative and quantitative comparisons between spore preparations. These enabling technologies are suitable for incorporation into standardized approaches for basic science, diagnostics, product development, or forensics purposes.

An analysis of insect flight indicates that in addition to the bending excitation (flapping), simultaneous excitation of the twisting degree-of-freedom is required to manipulate the control surface adequately. By adding a layer of angled piezoelectric segments to a Pb(Zr,Ti)O-3 (PZT) bimorph actuator, a bend-twist coupling may be introduced to the flexural response of the layered PZT, thereby creating a biaxial actuator capable of driving wing oscillation in flapping wing MAVs. The present study presents numerical solutions to governing equations for quasi-static three-dimensional bending of functionally-modified bimorph designs intended for active bend-twist actuation of cm-scale flapping wing devices. The results indicate a strong dependence of bimorph deflection on overall length. Further, the width and angle of orientation of the angled piezoelectric segments may be manipulated in order to increase or decrease the length effects on bimorph deflection. The relationships of geometry and orientation of the angled segments with bimorph flexural response are presented.

The nanofibers were introduced at ply interfaces using two different approaches while the nanoparticles were mixed into the matrix material. Behavior was experimentally characterized by determining the fracture toughness of flat carbon-fiber composite coupons using the double cantilever beam (DCB) test according to ASTM D5528. The nanofibers were introduced to the composite coupons by directly electrospinning the fibers onto the ply surfaces or transferring the fibers from an interim substrate, or "nanomat", while the nanosilica particles were mixed into the resin system during vacuum bagging hand layup. Testing facilitated the calculation of Mode I strain energy release rates. Preliminary results show that when compared to a baseline coupon without nanoreinforcement, there is a 54.5%, 43.1%, and 26.9% reduction in G(avg) for the nanomat, nanosilica, and directly deposited nanomaterial coupons, respectively. Directly deposited nanofibers outperformed the nanosilica reinforcement by 16.2% and the nanomat approach by 27.6%. Basic materials (carbon-fiber ply material and matrix system) and incomplete composite consolidation were cited as contributors to poor test coupon quality and detrimental to Mode I performance.

The objective of the research is to exploit unique phenomena for the development of novel technology to enhance warfighter capabilities and produce precision weapons. The key technology areas that the authors are exploring include nano-based microsensors, nano-energetics, nano-batteries, nano-composites, and nano-plasmonics. By integrating nano-based devices, structures, and materials into weaponry, the Army can revolutionize existing (and future) missile systems by significantly reducing the size, weight and cost. The major research thrust areas include the development of chemical sensors to detect rocket motor off-gassing and toxic industrial chemicals; the development of highly sensitive/selective, self-powered miniaturized acoustic sensors for battlefield surveillance and reconnaissance; the development of a minimum signature solid propellant with increased ballistic and physical properties that meet insensitive munitions requirements; the development of nano-structured material for higher voltage thermal batteries and higher energy density storage; the development of advanced composite materials that provide high frequency damping for inertial measurement units' packaging; and the development of metallic nanostructures for ultraviolet surface enhanced Raman spectroscopy. The current status of the overall AMRDEC Nanotechnology research efforts is disclosed in this paper. Critical technical challenges, for the various technologies, are presented. The authors' approach for overcoming technical barriers and achieving required performance is also discussed. Finally, the roadmap for each technology, as well as the overall program, is presented.

TI Matting Solutions for Low-Volume Roads SO TRANSPORTATION RESEARCH RECORD LA English DT Article AB An evaluation of 11 commercial roadway matting systems was conducted to determine their effectiveness in carrying heavy vehicle traffic over loose-sand subgrades. Three of the 11 matting systems were also evaluated under the same loading conditions over soft, fine-grained subgrades. Matting product types included high-density polyethylene, aluminum, fiberglass, and polyester. System installation methods included continuous rolls of material, segmented rolls, and connection of individual panels. The matting products were assembled in test sections of various sizes, which depended on individual panel dimensions and product availability. The mats were trafficked with a 7-ton, six-wheeled U.S. Marine Corps transport truck loaded with a 7-ton payload until 20% of the mat section was no longer reusable or 2,000 truck passes were achieved. Earth pressure cells were installed under nine of the sand test sections to monitor load distributions provided by the matting systems. On the basis of the test results, recommendations are given for selecting the best roadway matting system types for use on low-volume roads with sand or soft, fine-grained subgrades.

We have compared the GaAs reference cell to undoped, n-doped and p-doped QD solar cell structures and found that the short circuit current, J(SC), of the undoped QD solar cell is comparable to that of the GaAs reference cell. On the other hand, while p-doping deteriorates the device performance, n-doping significantly increases J(SC) without degradation of the open circuit voltage, V-OC. The photovoltaic device, n-doped to provide approximately six electrons per dot, demonstrates 60% increase in J(SC), from 15.07 mA/cm(2) to 24.30 mA/cm(2). Strong increase in the photoresponse and J(SC) of the IR portion of the solar spectrum has been observed for the n-doped structures. From the photoluminescence data, the electron capture noticeably dominates over hole capture leading to an accumulation of electrons in the dots. We have observed that ODs with built-in charge (Q-BIC) enhances harvesting of IR energy, suppresses the fast electron capture process, and stabilizes the open circuit voltage. All of these factors lead to a significant improvement of the cell efficiency. C1 [Sablon, K. A.; Little, J. W.; Olver, K. A.] USA, Res Lab, Adelphi, MD 20783 USA.

Recent work has shown that high resolution thermal cameras can passively and remotely obtain an analog to EDA by assessing the activation of facial eccrine skin pores. This paper investigates a method to distinguish facial skin from non-skin portions on the face to generate a skin-only Dynamic Mask (DM), validates the DM results, and demonstrates DM performance by removing false pore counts. Moreover, this paper shows results from these techniques using data from 20+ subjects across two different experiments. In the first experiment, subjects were presented with primary screening questions for which some had jeopardy. In the second experiment, subjects experienced standard emotion-eliciting stimuli. The results from using this technique will be shown in relation to data and human perception (ground truth). This paper introduces an automatic end-to-end skin detection approach based on texture feature vectors. In doing so, the paper contributes not only a new capability of tracking facial skin in thermal imagery, but also enhances our capability to provide non-contact, remote, passive, and real-time methods for determining autonomic nervous system responses for medical and security applications.

Consequently, we discovered a surprising low-pass band gap property, as opposed to the traditional sharp band-pass band-gaps. In other words, there exists a minimum amount of photon energy n (h) over barw shining on CNT is necessary to excite the semiconductor CNT into free electrons. Applying a static magnet along the longitudinal direction, the conduction electron and holes will spiral in the opposite direction over the surface reducing the current density and the collision recombination chance will therefore be reduced when travelling from the cathode end to the anode end, driven internally by the asymmetric semiconductor-metal (using Ag & Pd) work functions (Schottky interface effect) for an automatic triode read out.

How can a hawk see a tiny running rabbit from miles above ground? How could that rabbit see the approaching hawk? This predator-prey interaction draws parallels with spotting a familiar person in a crowd. We assume that mammal eyes use peripheral vision to perceive unexpected changes from our memory, and then use our central vision (fovea) to pay attention. The difference between an image and our memory of that image is usually small, mathematically known as a 'sparse representation'. The VS communicates with the brain using a finite reservoir of neurotransmittents, which produces an on-center and thus off-surround Hubel/Wiesel Mexican hat receptive field. This is the basis of our model. This change detection mechanism could drive our attention, allowing us to hit a curveball. If we are about to hit a baseball, what information extracted by our HVS tells us where to swing? Physical human features such as faces, irises, and fingerprints have been successfully used for identification (Biometrics) for decades, recently including voice and walking style for identification from further away. Biologically, humans must use a change detection strategy to achieve an ordered sparseness and use a sigmoid threshold for noisy measurements in our Hetero-Associative Memory [HAM] classifier for fault tolerant recall. Human biometrics is dynamic, and therefore involves more than just the surface, requiring a 3 dimensional measurement (i.e. Daugman/Gabor iris features). Such a measurement can be achieved using the partial coherence of a laser's reflection from a 3-D biometric surface, creating more degrees of freedom (d.o.f.) to meet the Army's challenge of distant Biometrics. Thus, one might be able to increase the standoff loss of less distinguished degrees of freedom (DOF).

When the interference to signal-of-interest ratio is greater than the dynamic range of the linear system, the system response may become non-linear. In this paper an adaptive analog cancellation approach is proposed to track and cancel the interference signal. The circuit's linear property is then recovered, enabling detection of the small magnitude signals. The concept was realized in an active RF sensor which demonstrated the effectiveness of the strategy. C1 [Szu, Harold] USA, Night Vis & Elect Sensors Directorate, Ft Belvoir, VA 22060 USA.

Current sensors seem to keep all, redundant or not. The Human Visual System's Hubel-Wiesel (wavelet) edge detection mechanism pays attention to changes in movement, which naturally produce organized sparseness because a stagnant edge is not reported to the brain's visual cortex by retinal neurons. Sparseness is defined as an ordered set of ones (movement or not) relative to zeros that could be pseudo-orthogonal among themselves; then suited for fault tolerant storage and retrieval by means of Associative Memory (AM). The firing is sparse at the change locations. Unlike purely random sparse masks adopted in medical Compressive Sensing, these organized ones have an additional benefit of using the image changes to make retrievable graphical indexes. We coined this organized sparseness as Compressive Sampling; sensing but skipping over redundancy without altering the original image. Thus, we turn illustrate with video the survival tactics which animals that roam the Earth use daily. They acquire nothing but the space-time changes that are important to satisfy specific prey-predator relationships. We have noticed a similarity between the mathematical Compressive Sensing and this biological mechanism used for survival. We have designed a hardware implementation of the Human Visual System's Compressive Sampling scheme. To speed up further, our mixed-signal circuit design of frame differencing is built in on-chip processing hardware. A CMOS trans-conductance amplifier is designed here to generate a linear current output using a pair of differential input voltages from 2 photon detectors for change detection-one for the previous value and the other the subsequent value, ('write' synaptic weight by Hebbian outer products;, read. by inner product & pt. NL threshold) to localize and track the threat targets. C1 [Szu, Harold] USA, Night Vis & Elect Sensors Directorate, Washington, DC 20310 USA.

In both cases, lithium's dendritic growth was suppressed by adding a small amount of sodium to a lithium electrolyte. This results in a co-deposition or alloying process that hinders dendrite growth. SEM images show a significant difference in morphology obtained by the addition of sodium. A smooth deposit was not enough for stable cycling of the lithium anode because of lithium's reactivity with the electrolyte. Vinylene carbonate (VC) was added to the N-1114-TFSI to form a stable SEI layer. Cyclic voltammetry and chronopotentiometry was carried out on tungsten and stainless steel electrodes to obtain efficiency measurements. The combination of a small amount of sodium in the electrolyte, along with VC as an SEI former, lead to significant improvements in cycling performance and efficiency.

The new generation of MEMS MMAs are fabricated by bulk micromachining of a single Silicon-On-Insulator wafer. Optical characterization of MEMS MMAs can be done by direct detection of the reflected beams or by using more advanced wavefront measuring techniques, such as a phase-shifting interferometer or Shack-Hartmann wavefront sensor. In the case of an interferometer, the geometry of the tested MMA can be calculated after performing the phase unwrapping procedure, which can be quite complex. In the latter case of the Shack-Hartmann wavefront sensor, careful selection of a high-quality array of microlenses is required in order to match the capabilities of the wavefront sensor to the measured wavefront produced by the MMA. The presented digital Shack-Hartmann technique is a modified approach for wavefront characterization based on digital processing of the interferometer data. The optical wavefront from the tested MMA is mixed with the reference wavefront. Then the recorded interference intensity image is Fourier transformed producing digitally synthesized images of the optical beams in the far field. Therefore, the digital version of the Shack-Hartmann wavefront sensor does not require the use of an array of microlenses and is primarily limited by the detector array geometry. One can digitally generate any configuration of subapertures corresponding to various geometries of microlenses. However, this new technique does require coherent optical mixing of the two wavefronts in order to produce the interference pattern.

One method is to compare observed values of band averaged absorption to radiative transfer models. This is most effective using bands where there is a single absorbing species. This work compares spectral attenuation of two oxygen absorption bands in the near-infrared (NIR) and visible (Vis) spectrum, centered at 762 nm and 690 nm, to passively determine range. Spectra were observed from a static test of a full-scale solid rocket motor at a 900m range. The NIR O-2 band provided range estimates accurate to within 3%, while the Vis O-2 band had a range error of 15%. A Falcon 9 rocket launch at an initial range of 13km was also tracked and observed for 90 seconds after ignition. The NIR O-2 band provided in-flight range estimates accurate to within 2% error for the first 30 seconds of tracked observation. The Vis O-2 band also provided accurate range estimates with an error of approximately 4%. Rocket plumes are expected to be significantly brighter at longer wavelengths, but absorption in the NIR band is nearly ten times stronger than the Vis band, causing saturation at shorter path lengths. An atmospheric band is considered saturated when all the in-band frequencies emitted from the rocket plume are absorbed before reaching the sensor. C1 [Vincent, R.

Unfortunately, most of these entitlements require a considerable amount of paperwork to process correctly, necessitating a great deal of patience, attention to detail, and composure from families at a time when their grief is raw. Even though the U.S. Army appoints a Casualty Assistance Officer (CAO) to help surviving family members through this process, the soldiers serving as CAOs tend to be inexperienced and oftentimes find themselves challenged to provide accurate and thorough assistance. Consequently, some families do not receive all benefits in a timely manner, and some entitlements may be over-looked entirely. To help with the military's Casualty Program, we have developed the Casualty Assistance Readiness Enhancement System (CARES), an information system that improves how the Department of the Army cares for military families in arguably their greatest time of need. The tool and associated process reduced the time required to complete forms, reduced the potential for errors on repetitive information, assisted CAOs through the process, and provided electronic copies of completed forms.

TI Computational and experimental investigation of morphology in thermoplastic elastomer gels composed of AB/ABA blends in B-selective solvent SO SOFT MATTER LA English DT Article ID DISSIPATIVE PARTICLE DYNAMICS; DIBLOCK COPOLYMERS; BLOCK-COPOLYMERS; TRIBLOCK-COPOLYMER; MESOSCOPIC SIMULATION; AQUEOUS-SOLUTION; MIXED MICELLES; POLYMER GELS; MICROPHASE SEPARATION; MECHANICAL-PROPERTIES AB Thermoplastic elastomer gels (TPEGs) are physically associating gels composed of ABA triblock copolymers that are highly swollen with a B selective solvent. A unique feature of TPEGs, when compared to typical chemically crosslinked gels, is that the properties are dictated by a combination of nano-scale block copolymer morphology and chain level structure. In this paper, we use dissipative particle dynamics (DPD) simulations to examine TPEGs composed of a binary mixture of AB and ABA block copolymers in a B-compatible solvent. The diblock and triblock differ in the block length, where the A and B block of the diblock chains are larger than those of the triblock. The DPD simulations illustrated numerous morphologies of these AB/ABA gels characterized by formation of pure and mixed micelles of various compositions, structures, and sizes. In addition, the ABA/AB copolymer ratio and processing conditions impacted the structural and mechanical properties of these blends. The simulation results were utilized to establish factors that affect an intermicellar distance and bridging chain fraction. The DPD-based morphology predictions were compared with experimental data based on atomic force microscopy (AFM) with good agreement. C1 [Sliozberg, Y. R.; Strawhecker, K. E.; Andzelm, J.

That is, it must not only maintain physical health but also psychological health. In fact, psychological health has a direct impact on the physiological health of people. The open literature suggests evidence-based strategies for helping individuals that suffer from psychological distress. Since technology is increasingly taking over the way humans relate with the world, virtual reality (VR) might be a great addition to psychotherapy sessions. In this chapter, the authors specifically discuss the effects of stress on one's health and provide a short background of VR contributions to human health.

To date, commercial UGV ladars have been flawed by one or more factors including low pixelization, insufficient range or range resolution, image artifacts, no daylight operation, large size, high power consumption, and high cost. ARL built a breadboard ladar based on a newly developed but commercially available micro-electro-mechanical system (MEMS) mirror coupled to a low-cost pulsed Erbium fiber laser transmitter that largely addresses these problems. Last year we integrated the ladar and associated control software on an iRobot PackBot and distributed the ladar imagery data via the PackBot's computer network. The un-tethered PackBot was driven through an indoor obstacle course while displaying the ladar data real-time on a remote laptop computer over a wireless link. We later conducted additional driving experiments in cluttered outdoor environments. This year ARL partnered with General Dynamics Robotics Systems to start construction of a brass board ladar design. This paper will discuss refinements and rebuild of the various subsystems including the transmitter and receiver module, the data acquisition and data processing board, and software that will lead to a more compact, lower cost, and better performing ladar. The current ladar breadboard has a 5-6 Hz frame rate, an image size of 256 (h) x 128 (v) pixels, a 60 degrees x 30 degrees field of regard, 20 m range, eyesafe operation, and 40 cm range resolution (with provisions for super-resolution or accuracy).

They are available in diverse forms and possess material properties not found in more traditional microfabrication materials originating from the integrated circuit industry. These include, for example, improved fracture strength, low Young's modulus, and high elongation. Many polymers also exhibit biocompatibility and chemical inertness which are desirable in challenging biological or chemical applications. Furthermore, low material and processing costs present interesting possibilities in MEMS both in terms of fabrication of novel research devices and mass production of inexpensive products. A variety of traditional and nontraditional processing approaches exists to manipulate polymeric materials as substrates, coatings, and sacrificial or structural layers in MEMS devices. A wide variety of polymer types and classifications exists (e.g., elastomers, epoxies, conductive polymers, hydrogels, thermosets, thermoplastics, etc.); it is the combination of material properties, processing conditions, and intended use (e.g., substrate, coating, sacrificial layer, or structural layer) that govern the selection of appropriate polymer type for a particular application. Several common MEMS polymer materials and their fabrication processes are reviewed here. The reader is also referred to Chapters 7, 8, and 9 for more in-depth discussions on wet/dry etching and lithography processes.

Fabrication process compatibility, complexity, and the limited availability of repeatable and reliable piezoelectric thin films have limited the incorporation of piezoelectric thin films in MEMS. Advances in materials processing and a move toward system-in-package (SIP) concepts have pushed piezoelectric thin film devices toward mainstream acceptance. The advances in piezoelectric aluminum (AlN) thin films for film bulk acoustic resonators (FBAR) [1] have encouraged using piezoelectric transduction as an alternative to electrostatic actuation in RF (radio frequency) MEMS applications. The FBAR devices have tremendous performance advantages and smaller size over conventional bulk-machined quartz surface acoustic wave devices (SAWs) making them ideal for cellular phones. To date, FBAR devices have exceeded the performance of electrostatically driven MEMS resonator and filters operating in cellular phone frequency bands (nominally 0.7-6 GHz). In addition to FBAR technology, piezoelectric actuation/sensing is being examined for a host of applications including RF MEMS, small-scale robotics, resonant mass sensors, and energy harvesting [2, 3]. This chapter focuses on materials selection, material processing, and integration of piezoelectric thin films with conventional MEMS fabrication processes. The first sections introduce the reader to the fundamentals of both ferroelectricity and piezoelectricity. The remainder of the chapter addresses processing of the key ferroelectric and piezoelectric materials, namely lead zirconate titanate (PZT), AlN, and zinc oxide (ZnO).

The cornerstone of proper specimen handling is communication between the ophthalmologist and the pathologist before, during, and after surgery. Conjunctival tissue presents unique surgical specimen handling challenges as the tissue has a propensity to curl up on itself, making it difficult to maintain proper tissue orientation and alignment. For pathologic evaluation of eyelid specimens, specimen orientation is the key. Proper specimen handling and discussion with the pathologist can help alleviate these difficulties.

The most obvious evidence of this is the widespread use of MMW full-body scanners, now commonly found in airports. The path to this point has been the result of the work of a wide range of experts from many scientific and engineering disciplines. This article represents one perspective of this progress. The development of MMW imagers, and all their associated component technologies, image processing techniques, clever engineering, etc. has been driven by a relatively small number of interesting applications. It has been known for about 70 years that RF energy can be used to "see" through things like clouds and detect, for example, hostile aircraft. As the RF frequency goes up to 35, 100, or 340 GHz, it becomes possible to image through obscurants with much improved resolution. However, as frequency increases, attenuation increases as well, so selecting the right frequency for the application is an important point. The challenge of seeing through obscurants such as fog, smoke and dust drives one towards a MMW imaging solution. Typical applications include guiding aircraft through low visibility conditions, detecting nearby watercraft in the fog, and searching for concealed weapons. So, while these capabilities have been demonstrated numerous times over the years, the practical and affordable implementation of the systems to accomplish these goals is where the real story lies.

The advantages of using a robot have been enumerated by many clinicians, however the true potential has yet to be realized. In addition, the systems available today are extraordinarily simple and cumbersome relative to the more sophisticated robotic systems used in other industries. However more important is the fact that the fundamental principles underlying robotics have yet to be exploited, such as systems integration, feedback control, automatic performance, simulation and rehearsal and integration into healthcare enterprise. By looking at robotic implementation in other industries, and exploring the new robotic technologies in the laboratories, it is possible to speculate on the future directions which would be possible in surgical robotics.

Force protection of military first responders is complicated by current international and coalition troop deployments for peacekeeping operations, counter terrorism, and humanitarian assistance missions that involve highly visible, politically sensitive, low intensity combat in urban terrain. The United States Department of Defense (DoD) has significantly invested in autonomous vehicles, and other robots to support its Future Force. The US Army Telemedicine and Advanced Technology Research Center (TATRC) has leveraged this DoD investment with augmented funding to broadly focus on implementing technology in each phase of combat casualty care. This ranges from casualty extraction, physiologic real-time monitoring, and life saving interventions during the "golden hour" while greatly reducing the risk to first responders. The TATRC portfolio of projects aims to develop, integrate, and adapt robotic technology for unmanned ground and air battlefield casualty extraction systems that operate in hostile environments that include enemy fire. Work continues on multiple ground extraction systems including a prototype dynamically balanced bipedal Battlefield Extraction Assist Robot (BEAR) capable of extracting a 300-500 pound casualty from a variety of rugged terrains that include urban areas and traversing stairs. The TATRC and the Defense Advanced Research Projects Agency (DARPA) are collaborating to investigate the use of Unmanned Aircraft Systems (UAS) to conduct casualty evacuation (CASEVAC) missions. TATRC has also sponsored research in robotic implementations of Raman and Laser-Induced Breakdown Spectroscopy (LIBS) to detect and identify potential chemical and biological warfare agents and explosive hazards to casualties and-first responders during the extraction process, and patient monitoring equipment with sophisticated telemedicine and patient monitoring equipment such as "smart stretchers" that allow for real-time physiologic monitoring throughout the combat casualty care process, from extraction to definitive care. Other projects are intended to build upon these monitoring systems and incorporate telerobotic and near autonomous casualty assessment and life saving treatment to the battlefield. These have included the DARPA Trauma Pod and several TATRC efforts to integrate robotic arms with the Life Support for Trauma and Transport (LSTAT) litter for robotic implementation of non-invasive technologies such as acoustic cauterization of hemorrhage via High Intensity Focused Ultrasound (HIFU). Several projects have explored the essential telecommunication link needed to implement telesurgery and telemedicine in extreme environments. UAS were leveraged to establish a telecommunication network link for telemedicine and telesurgery applications in extreme situations. Another collaborative telesurgery research project at the NASA Extreme Environment Mission Operations (NEEMO) included performing telesurgery in an undersea location. Research into identification and solutions of the limitations of telecommunication and robotics that prevent robust casualty interventions will allow future medical robots to provide robust casualty extraction and care that will save the lives and limbs of our deployed warfighters.

The impedivity of various soils are measured in-situ in field experiments using a custom apparatus, consisting of a probe head and accompanying custom electronics. Four galvanic electrodes are fixed in the probe head, and arranged in a Wenner array, such that the geometric factor is 1.00 m. In this way, impedance measurements (in Omega) are easily converted to estimates of impedivity (in Omega.m). Field measurements made in-situ are important for obtaining accurate results, because impedance measurements typically change value significantly once soil samples are extracted from their natural environment. These changes are due to changes in the grain boundaries, as well as changes in moisture, temperature, etc. Soil impedivity signatures collected on a variety of soils in the south west region of the USA over the frequency band up to 1 MHz are presented.

Maps depicting relative change in phase and the theoretical relative change in SWE between satellite acquisitions are created for 3-day periods at the end of March 1994 using both ascending and descending ERS-1 overpasses. The theoretical coefficient relating relative change in phase and relative change in SWE for C-band is found to be at least twice as large as what is expected when using a simple single-layer snow model for this study area and time period. Without any direct measurements of SWE on the ground, station measurements of snow depth and hourly wind are linked to each 3-day relative change in phase map. Along with a qualitative assessment, quantitative measures of the rate and magnitude of phase change around these stations are directly compared to the hourly wind data for a given 3-day period. InSAR-derived maps acquired around a measured precipitation event show a considerable relationship to the predominant direction of strong winds over each 3-day period while maps acquired around no measureable precipitation depict much less correlation between phase change and predominant direction of strong winds. Despite limited ground measurements to infer snowpack conditions, these results show continued promise for the InSAR technique to measure changes in snowpack conditions (e.g. SWE) at much higher resolutions than manual sampling methods or passive microwave remote sensing. The extension of this technique to current L-band InSAR satellite platforms is also discussed. C1 [Deeb, Elias J.] USA, Cold Reg Res & Engn Lab, Hanover, NH 03755 USA.

In this work, we explore atomic layer deposition (ALD) as a means to coat and protect electrospun nylon-6 nanofibers. Exposing nylon to trimethyl aluminum (TMA) during ALD of aluminum oxide results in significant fiber degradation. Protecting fibers with a bilayer of ALD ZnO and an organic-inorganic hybrid polymer by molecular layer deposition maintains the shape of the original nanofibers, but chemical modification is still detected. These coating processes may help enable nanofibers with stable physical properties under chemical exposure. (C) 2011 The Electrochemical Society. [DOI: 10.1149/1.3609046] All rights reserved.

The proposed technique is aimed to optimize an ensemble of kernel-based one class classifiers, such as Support Vector Data Description (SVDD) classifiers, by estimating optimal sparse weights. In this method, hyperspectral signatures are first randomly sub-sampled into a large number of spectral feature subspaces. An enclosing hypersphere that defines the support of spectral data, corresponding to the normalcy/background data, in the Reproducing Kernel Hilbert Space (RKHS) of each respective feature subspace is then estimated using regular SVDD. The enclosing hypersphere basically represents the spectral characteristics of the background data in the respective feature subspace. The joint hypersphere is learned by optimally combining the hyperspheres from the individual RKHS, while imposing the l1 constraint on the combining weights. The joint hypersphere representing the most optimal compact support of the local hyperspectral data in the joint feature subspaces is then used to test each pixel in hyperspectral image data to determine if it belongs to the local background data or not. The outliers are considered to be targets. The performance comparison between the proposed technique and the regular SVDD is provided using the HYDICE hyperspectral images.

We find that for isotropic grids, node-centered approaches produce less error than cell-centered approaches for comparable cell size. In contrast, cell-centered schemes produce less discretization error on stretched meshes. In 3D, careful treatment of non-planar faces is necessary to avoid first-order errors. We introduce a new corrected scheme which enhances the accuracy of the node-centered scheme to third-order.

The mechanisms of airbag deployment can produce particles ideal for scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDS) analysis. A recent study published by Berk studied airbags with vents and showed that it is possible for particles generated from the deployment of these airbags to deposit on surfaces in the vehicle as the airbags deflate.(1) Another paper published by Berk reported particles similar in morphology and composition to primer gunshot residue (GSR) are produced by side impact airbags.(2) This paper's aim will be to show mid-point results of a study still in progress in which non-vented airbags were analyzed to determine if they exhibited the same particle depositing features as their vented airbag counterparts. Further investigation in this study is being performed to find more airbags which produce primer gunshot residue-like particles containing lead, barium, and antimony from airbag deployment. To date, the study has resulted in (1) non-vented airbags exhibiting deposition of particles suitable for SEM/EDS analysis and (2) no gunshot residue-like particles being detected from the airbag residues studied thus far.

These techniques include flying actual threat MANPADS against stationary ASE with simulated aircraft signatures, testing installed ASE systems against simulated threat signatures, and laboratory hardware-in-the-loop (HWIL) testing with simulated aircraft and simulated missile signatures. All of these tests lack the realism of evaluating installed ASE against in-flight MANPADS on a terminal homing intercept path toward the actual ASE equipped aircraft. This limitation is due primarily to the current inability to perform non-destructive MANPADS/Aircraft flight testing. The U. S. Army Aviation and Missile Research and Development and Engineering Center (AMRDEC) is working to overcome this limitation with the development of a recoverable surrogate MANPADS missile system capable of engaging aircraft equipped with ASE while guaranteeing collision avoidance with the test aircraft. Under its Missile Airframe Simulation Testbed - MANPADS (MAST-M) program, the AMRDEC is developing a surrogate missile system which will utilize actual threat MANPADS seeker/guidance sections to control the flight of a surrogate missile which will perform a collision avoidance and recovery maneuver prior to intercept to insure non-destructive test and evaluation of the ASE and reuse of the MANPADS seeker/guidance section. The remainder of this paper provides an overview of this development program and intended use. C1 [Clements, Jim] USA, Aviat & Missile Res Dev & Engn Ctr, Redstone Arsenal, AL USA.

MAVRIC is a dynamic object-based energy conserved scene compositor that can seamlessly convolve distributed scene elements into temporally aligned physics-based scenes for enhancing existing AMRDEC scene generation codes. The volumetric compositing process accepts input independent of depth order. This real-time compositor framework is built around AMRDEC's ContinuumCore API which provides the common messaging interface leveraging the Neutral Messaging Language (NML) for local, shared memory, reflective memory, network, and remote direct memory access (RDMA) communications and the Joint Signature Image Generator (JSIG) that provides energy conserved scene component interface at each render node. This structure allows for a highly scalable real-time environment capable of rendering individual objects at high fidelity while being considerate of real-time hardware-in-the-loop concerns, such as latency. As such, this system can be scaled to handle highly complex detailed scenes such as urban environments. This architecture provides the basis for common scene generation as it provides disparate scene elements to be calculated by various phenomenology codes and integrated seamlessly into a unified composited environment. This advanced capability is the gateway to higher fidelity scene generation such as ray-tracing. The high speed interconnects using PCI Express and InfiniBand were examined to support distributed scene generation whereby the scene graph, associated phenomenology, and the scene elements can be dynamically distributed across multiple high performance computing assets to maximize system performance.

When a monostatic radar system employs this waveform for increased range resolution measurements on an object with motion relative to the radar platform, simple changes in the received waveform arise, requiring fine motion compensation on a per-pulse basis. These motion effects include phase, frequency and frequency slope offsets which vary according to the transmitted pulse frequency and frequency rate, and the object range and range rate. All three offsets are easily compensated by complementary offsets in Direct Digital Synthesizer outputs used to form frequency conversion LO signals in the radar receiver. Radars employing stepped frequency LFM waveforms may be tested in a Hardware-in-the-Loop (HWIL) facility in simulations involving scenes or objects with radar-relative motion. Under these conditions, the motion effects on the radar receiver input signals must be accurately computed, synthesized and must modify the transmit signal prior to its return to the receiver. Engineers at the U. S. Army AMRDEC Advanced Simulation Center have developed signal processing techniques for accurate simulation of fine range motion effects to support HWIL testing of pulsed LFM radar systems. This paper provides an analysis of the signal processing involved for a simple model of an HWIL RF signal generation chain. Some results are presented from successful application of the motion simulation methods in an HWIL test setting. C1 USA, Air & Missile Def Simulat SSDD, AMRDEC, Redstone Arsenal, AL 35898 USA.

For the purposes of detection and classification, there are advantages and disadvantages to using either seismic or ultrasonic-sensing modalities individually to detect, identify, and classify successfully a subject to some degree. The seismic modality provides a clean, separable set of results for walkers close to the sensor but in general fails to be as successful at a larger stand-off due to ground wave attenuation and provides only some level of detection. The ultra-sonic modality provides stronger detection results from a greater stand-off distance in direct comparison to the seismic sensor due to higher fidelity of the signal. However, the resulting signature is harder to separate into individual walk-cycle events due to the broadband nature of the ultrasonic profile. In light of the advantages and disadvantages, it is desirable to utilize the capabilities of both sensors to create a framework for a robust singular solution for detection, identification, and classification of the actor(s) within the scene. In this particular case, data fusion techniques such as Hidden Markov Models and Dempster Shafer Theory provide a framework and methodology for exploiting each modality in an optimized and complementary fashion. In a probabilistic sense, this means that the chance of a successful detection is increased through a decision model that uses both the seismic and ultrasonic detection results to detect a target with high confidence.

Protection is addressed in the planning stages of any secure facility in order to provide adequate defense of critical personnel and assets. Given the increased threats domestically and globally, the security missions are dynamic and technically challenging. Operational forces need to be proactive and leave no gaps within the complex, integrated and layered defensive posture. This paper will discuss a research and development effort to use Government off the Shelf Software (GOTS) to complete this task; by linking high resolution simulation / training software and an operational simulation analysis software in a distributed environment.

Hotchkiss, Rollin TI Comparing the capability of distributed and lumped hydrologic models for analyzing the effects of land use change SO JOURNAL OF HYDROINFORMATICS LA English DT Article DE GSSHA; HEC-HMS; Landuse change modeling; Lumped and distributed models ID RUNOFF; RAIN AB Empirically based lumped hydrologic models have an extensive track record of use for various engineering applications. Physically based, multi-dimensional distributed models have also been in development and use for many years. Despite the availability of high resolution data, better computational resources and robust, numerical methods implemented in such models, their usage is still limited, especially in the realm of surface water runoff simulation. Lumped models are often extended to solve complex hydrologic problems that may be beyond their capabilities. Here we attempt to differentiate the ability of lumped and distributed models to analyze a common watershed development issue such as land use change. For this, we employ two common US Army Corps of Engineers (USACE) models, well established in the literature and application, using the Hydrologic Engineering Center - Hydrologic Modeling System (HEC-HMS) model in a fully lumped mode and the fully distributed model Gridded Surface Subsurface Hydrologic Analysis (GSSHA). A synthetic watershed is used to establish that a distributed model like GSSHA more intuitively simulates land use change scenarios by distinguishing the spatial location of the change and its effects on the watershed response. An actual watershed at Tifton, Georgia is used to validate the observations made from the synthetic watershed. C1 [Paudel, Murari; Nelson, E.

It is reasonable to consider that live virus vaccines may also be effective for the prevention of other alphaherpesviruses, such as herpes simplex virus 1 (HSV-1) and 2 (HSV-2). An HSV-1 mutant strain that is deleted in glyco protein E (gE), NS-gEnull, is replication competent but is defective in spread from one epithelial cell to another, from epithelial cells to axons, and from the neuron cell body into axons. The defect in spread likely accounts for the favorable safety profile of the live virus vaccine candidate in mice. The NS-gEnull mutant is also defective in immunoglobulin G (IgG) Fc receptor binding, which is a process used by the virus to escape antibody attack. NS-gEnull when used as an immunogen is highly effective in providing protection against epidermal and vaginal challenge by wild-type (WT) HSV-1 and HSV-2. NS-gEnull represents a novel HSV-1 vaccine approach that retains replication competency while impairing virus spread at the inoculation site and in neurons. Only gE is deleted from the vaccine strain, ensuring that most viral antigens are presented to the host. This strategy is worth considering for prevention of HSV-1 and possibly HSV-2.

TI 'Technology Determines Tactics': The Relationship between Technology and Doctrine in Chinese Military Thinking SO JOURNAL OF STRATEGIC STUDIES LA English DT Article DE China; Technology; Tactics AB Does 'doctrine drive technology' or does 'technology drive doctrine'? For the United States with its advanced industrial and technological base, many examples of 'doctrine driving technology' can be found. For the People's Liberation Army (PLA), however, most evidence from military sources indicates that 'technology drives doctrine' or, as the Chinese say, 'technology determines tactics' (but not necessarily strategy). Within an overarching Chinese strategic framework, tactics and doctrine will be developed appropriate for (a) the weapons and technologies that are actually in the Chinese armed forces and (b) the people who must operate and maintain them. The Chinese civilian and military leadership has designated 2049 for completion of the modernization of the Chinese armed forces, a date selected in conjunction with the target for achieving China's main strategic priority, national economic modernization. Barring a major change in the strategic or domestic environment, we can expect that Beijing will continue to pursue the development of new weapons and technology in a manner consistent with the larger goal of national economic development. Exactly how China fights in the future will be dependent upon the weapons and technologies available-and they will be employed within the parameters defined by active defense and People's War.

For shallow Half Moon Lake, Wisconsin, the Al:P ratio varied in a negative exponential pattern as a function of increasing redox-P concentration. While more Al was needed to inactivate higher concentrations of redox-P, inactivation was more efficient at higher redox-P. The Al:P ratio needed to bind 90% of the redox-P exceeded 150:1 for redox-P concentrations 0.2 mg/g and approached 20:1 for concentrations 2.0 mg/g. Competition for binding sites by other constituents in relation to redox-P concentration may be responsible for this pattern. Although organically bound P was not important in Half Moon Lake, it may be in other cases, and lake specific assays are recommended to determine the most appropriate Al dosage. Even then, slower processes of P release from labile organic P and vertical diffusion may not be addressed by higher Al dosages, and more research is warranted. Because redox-P varied horizontally as a result of lake bathymetry, variations in the Al:P ratio were considered for lake-wide alum dose calculation for Half Moon Lake. The estimated lake-wide average dosage of 115 g Al/m2 was high but similar to other recent effective treatments reported in the literature.

The primary sensing modality is hyperspectral, where a national asset is expected to fly over the region of interest acquiring and processing data in real time, but transmitting only the corresponding data of scene anomalies, their spatial relationships in the imagery, range and navigational direction.

Penetration of a fragment-like projectile was simulated using finite element (FE) and meshfree particle formulations. Extreme deformation and failure of the material during the penetration event were modeled with several approaches to evaluate each as to how well it represents the actual physics of the material and structural response. A steel Fragment Simulating Projectile (FSP) - designed to simulate a fragment of metal from a weapon casing - was simulated for normal impact into a flat square plate. A range of impact velocities was used to examine levels of exit velocity ranging from relatively small to one on the same level as the impact velocity. The numerical code EPIC, used for all the simulations presented herein, contains the element and particle formulations, as well as the explicit methodology and constitutive models needed to perform these simulations. These simulations were compared against experimental data, evaluating the damage caused to the projectile and the target plates, as well as comparing the residual velocity when the projectile perforated the target.

That is, the narrow light beam retains its propagation direction even after entering another medium at an oblique angle. The result reveals novel features of nano-beams and may have applications in precise biomedical measurement or micro optical device. (C) 2010 Elsevier Ltd. All rights reserved.

TI Continuity of Instantaneous Wave Overtopping Discharge with Application to Stream Power Concepts SO JOURNAL OF WATERWAY PORT COASTAL AND OCEAN ENGINEERING-ASCE LA English DT Article DE Overtopping AB During nine small-scale laboratory experiments simulating combined wave overtopping and storm surge overflow on a trapezoidal levee, time series measurements of flow thickness and velocity were acquired at a location on the levee crest and at a location on the landward-side slope. Flow thickness and velocity were combined to estimate time series of the instantaneous discharge. Comparisons of the calculated overtopping discharge time series at the two locations revealed that the time series of instantaneous discharge was the same at both locations with the only difference being a short phase lag. Individual peaks of the discharge time series were examined, and an empirical expression was determined for the root-mean-squared discharge peak. The largest discharge peaks were overestimated by the Rayleigh distribution. For locations on the landward-side slope where the friction slope is approximately the same as the levee slope, it is possible to derive a stream power probability density function based on the overtopping discharge cumulative exceedance probability. The stream power probability density function may be a useful tool for assessing erosion potential of overtopped earthen levees.

Clouds not only conceal the ground, they also cast shadows, which cause either a reduction or total loss of information in an image, by reducing the illumination falling on the shadowed pixels. Ocean color bio-optical inversion algorithms rely on measurements of remote sensing reflectance (R-rs(lambda)) at each pixel. If shadows are not removed properly across a scene, erroneous R-rs(lambda) values will be calculated for the shadowed pixels, leading to incorrect retrievals of ocean color products such as chlorophyll. The cloud shadow issue becomes significant especially for high-resolution sensors such as the Hyperspectral Imager for the Coastal Ocean (HICO). On the other hand, the contrast of pixels in and outside a shadow provides opportunities to remove atmospheric contributions for ocean color remote sensing. Although identifying cloud is relatively straightforward using simple brightness thresholds, identifying their shadows especially over water is quite challenging because the brightness of the shadows is very close to the brightness of neighboring sunny regions especially in deep waters. In this study, we present automated procedures for our recently proposed cloud shadow detection technique called the Cloud Shadow Algorithm (CSA) and Lee et al. (2007) cloud and shadow atmospheric correction algorithm. We apply both automated procedures to HICO imagery and show examples of the results.

The linear finite depth dispersion relation for surface gravity waves was used to determine nearshore ocean depth from successive images acquired of the coastal area. Principal component transformations of co-registered 8-color multispectral images were found to very effectively highlight wave crests in the surf zone. Time sequential principal component images then contain both spatial and temporal information. From these change detection images, wave celerity could be determined and depth inversion could be performed. For waves farther from shore, the principal component transformation no longer highlighted wave crests, but crests could be resolved within a single RGB composite image with equalization enhancement. The wavelength of a wave above a point of known depth was measured. The wave period method was used to determine depth for other waves in the propagation direction of this wave. Depth calculations using these methods compared favorably to reference bathymetry. The spatial resolution for this method of determining depth is higher and perhaps more accurate than the reference bathymetry used in this study, particularly in the surf zone.

This method relies on quantifying the difference in image texture between the relatively smooth surface of the river water and the rougher surface of the vegetated land or built environment bordering it and then segmenting the image into high and low roughness regions. The edges of the low roughness regions then define the river banks. The method can be coded in any language without recourse to proprietary tools and requires minimal operator intervention. As this sort of imagery is increasingly being made freely available through such services as Google Earth or Worldwind this technique can be used to extract river features when more specialized imagery or software is not available.

The polymers were extruded to determine the mechanophore activity in the solid state. The extent of gDHC ring opening depends on both the polymer composition and the macroscopic shear stress, ranging from 6.0% to over 30% after an hour of extrusion. In addition, the 2,3-dibromoalkene formed from mechanical activation of the gem-dibromocyclopropane was found to undergo subsequent nucleophilic substitution by chloride in the solid state. The number of solid-state substitution reactions far exceeds the number of main-chain bonds broken, a finding with implications for the future use of mechanophores in self-strengthening or self-healing polymers.

Salinity and temperature are environmental variables that limit the spread of many non-native fishes. We hypothesised that combinations of temperature and salinity will interact to affect survival, growth, and reproduction of Nile tilapia, Oreochromis niloticus, introduced into Mississippi, USA. Tilapia withstood acute transfer from fresh water up to a salinity of 20 and survived gradual transfer up to 60 at typical summertime (30 degrees C) temperatures. However, cold temperature (14 degrees C) reduced survival of fish in saline waters >= 10 and increased the incidence of disease in freshwater controls. Although fish were able to equilibrate to saline waters in warm temperatures, reproductive parameters were reduced at salinities >= 30. These integrated responses suggest that Nile tilapia can invade coastal areas beyond their point of introduction. However, successful invasion is subject to two caveats: (1) wintertime survival depends on finding thermal refugia, and (2) reproduction is hampered in regions where salinities are >= 30. These data are vital to predicting the invasion of non-native fishes into coastal watersheds. This is particularly important given the predicted changes in coastal landscapes due to global climate change and sea-level rise.

Chemical analysis was performed on grease samples from fielded bearings and compared to fresh grease and samples taken from bearings run for extended times in a laboratory environment. Size exclusion chromatography and Fourier transform infrared spectroscopy were used to investigate the condition of the grease, and evidence of additive depletion, oil evaporation, and thickener degradation were seen, consistent with results reported by other authors. Given the relatively light loading conditions experienced by the test bearings, they were able to continue operating at high temperature despite having most of the original oil depleted from the grease.

For submersed aquatic macrophytes restricted to free CO(2) uptake for photosynthesis, the addition of lime may be an effective means of suppressing growth and propagation. Fanwort (Cabomba caroliniana Grey) is an invasive species to Midwestern and northeastern United States and Canada, predominantly found in low alkalinity, softwater systems, and could be susceptible to inorganic carbon limitation after lime application. Growth response of fanwort (invasive green phenotype) to hydrated lime addition was examined in replicate softwater (pH similar to 7; total alkalinity similar to 80 mu M) experimental tanks to test this hypothesis. Modest lime concentrations of 55 and 160 mu M were required to increase pH to 9 and 10, respectively, versus pH 7 in control tanks. Free CO(2) decreased from similar to 20 mu M in the controls to similar to 0.1 and similar to 0.01 mu M in tanks treated with 55 and 160 mu M lime, respectively. Fanwort shoot biomass decreased to 36% and only 8% of the control mean biomass for tanks treated with 55 and 160 mu M lime, respectively, indicating negative growth response to lime application. These patterns suggested that lime addition may be effective in suppressing fanwort growth. C1 ERDC Eau Galle Aquat Ecol Lab, Spring Valley, WI 54767 USA.

In the Riemannian geometry of quantum computation, the quantum evolution is described in terms of the special unitary group of n-qubit unitary operators with unit determinant. The group manifold is taken to be Riemannian. To elaborate on several aspects of the methodology on the group manifold, the Riemannian curvature, geodesic equation, Jacobi equation, generic lifted Jacobi equation, lifted Jacobi equation for varying penalty parameter, and the so-called geodesic derivative are reviewed. This is important for investigations of conjugate points and the global characteristics of geodesic paths in the group manifold, and the determination of optimal quantum circuits for carrying out a quantum computation.

Robust handling of DEM depressions is essential for reliable extraction of connected drainage networks from this type of data. The least-cost flow routing method implemented in GRASS GIS as the module rwatershed was redesigned to significantly improve its speed, functionality, and memory requirements and make it an efficient tool for stream mapping and watershed analysis from large DEMs. To evaluate its handling of large depressions, typical for remote sensing derived DEMs, three different methods were compared: traditional sink filling, impact reduction approach, and least-cost path search. The comparison was performed using the Shuttle Radar Topographic Mission (SRTM) and Interferometric Synthetic Aperture Radar for Elevation (IFSARE) datasets covering central Panama at 90m and 10 m resolutions, respectively. The accuracy assessment was based on ground control points acquired by GPS and reference points digitized from Landsat imagery along segments of selected Panamanian rivers. The results demonstrate that the new implementation of the least-cost path method is significantly faster than the original version, can cope with massive datasets, and provides the most accurate results in terms of stream locations validated against reference points.

Wang, Changzheng TI Toxicity of Rotenone to Giant River Freshwater Prawn Macrobrachium rosenbergii SO NORTH AMERICAN JOURNAL OF AQUACULTURE LA English DT Article ID ANTIMYCIN AB Aquaculturists have often suffered predation losses in the production of freshwater giant river prawn Macro-brachium rosenbergii due to the presence of wild fish species in culture ponds. The piscicide rotenone is widely used to remove undesirable fish species from ponds. Although evidence in the technical literature suggests that crustaceans generally have a higher tolerance to rotenone than fish, there are currently no data on the acute or chronic toxicity of rotenone to juvenile freshwater prawns. In this study, two static acute-toxicity bioassays (96 h) were conducted using Prentox Prenfish (5% active ingredient) rotenone to determine the median lethal concentration (LC50) for juvenile freshwater prawns (average weight = 0.55 g, SD = 0.25; length = 41.43 mm, SD = 6.45). In bioassay 1, prawns were exposed to rotenone concentrations of 1.0, 3.0, 5.0, and 10.0 mg/L. In bioassay 2, prawns were exposed to rotenone concentrations of 2.2, 3.6, 6.0, 10.0, and 16.7 mg/L. All rotenone concentrations used in the study were based on the total product of the commercial rotenone formulation. The LC50 calculated in bioassay 1 was 6.2 mg/L, and the LC50 calculated in bioassay 2 was 7.5 mg/L. Freshwater prawns were able to tolerate 3.0 to 3.6 mg/L of rotenone with no mortality or apparent adverse effects during the study. Prawns held at the end of each bioassay for 5 d showed no signs of delayed effects from rotenone exposure. Data from this study indicate that juvenile prawns should be able to tolerate the concentrations of rotenone required to eradicate certain problematic wild fish species.

By defining different levels of Al Qaeda, core, periphery, and movement, this article engages current debates about the threat by focusing on the operational differences across these three levels. Contrary to conventional wisdom about operational efficiency, the social movement has a higher success rate but the core imposes greater costs as measured by casualties. The cells or networks actually executing the attacks also display substantive differences. The social movement networks organize in smaller cells than either affiliated groups or the core; however, they display greater levels of connectedness. The affiliated and organization cells display fewer connections, suggestive of more disciplined operational procedure despite lower success rates. These patterns reflect fundamental differences across characterizations of Al Qaeda, and have significant implications for counterterrorism efforts.

The research was conducted by a university, industry, and government team with the primary objective of obtaining fundamental understanding of the mechanisms through which additive compounds blended into a fuel affect soot emissions. The work involved coordinated testing across a suite of laboratory devices: a shock tube, a well-stirred reactor, a premixed flat flame, an opposed-jet diffusion flame, and a high-pressure turbulent reactor. This article summarizes results on the addition of nitroalkanes to a base fuel consisting of n-heptane and toluene as a simple surrogate for jet fuels. In these experiments, the nitroalkanes serve as chemical probes of key reactions leading to soot. The effects of nitroalkane addition on soot were found to be device and condition dependent with no simple trends across the suite of devices.

The cadets (N = 30) completed an 8-day combat survival course characterized by sleep and food deprivation, continuous operations, and altered circadian entrainment cues. Results indicated that self-ratings of SA did not correlate consistently with expert-observer SA ratings, and self-ratings were consistently higher than expert-observer ratings. The results are congruent with expected effects of these extreme conditions on cognition and self-awareness, demonstrate a pronounced self-enhancement bias and suggest that subjective measures of SA are not likely to provide valid estimates of SA under extreme conditions.

Such display proliferation makes the task of managing limited visual attention while searching for information extremely demanding and the potential for critical information loss due to visual demand overload. Cueing has traditionally provided a performance advantage in search tasks, with the current experiment exploring whether and how a specific tactile display format could guide visual attention. In particular, the use of the tactile cues decreased search response time by more than 30%. This was not a trade of speed for accuracy because the frequency of missed signals themselves was also reduced by approximately 70%, and false positives were suppressed by the addition of the tactile cue by over 50%. These findings represent useful foundational outcomes against which to compare other forms of sensory cueing. C1 [Merlo, James] US Mil Acad, Dept Behav Sci & Leadership, West Point, NY 10996 USA.

One explanation for this is that managers fear that individuals will draw negative conclusions about their leadership abilities if they use an inappropriate degree of decision-making empowerment (DME). The current research explored this hypothesis, using scenarios to manipulate DME, organizational setting, manager gender, and task outcome. Officer cadets (N = 173) judged appropriateness of the manager's use of empowerment; degree of leadership shown; and willingness to work for the manager. Cadets saw high DME as significantly more appropriate than low, resulting in significantly higher leadership attributions and a greater willingness to work for the manager. Findings held regardless of context or gender. Task outcome also affected attributions. C1 [Campbell, Donald J.] US Mil Acad, Dept Behav Sci & Leadership, West Point, NY 10996 USA.

However, less research has examined BF as a buffer against the negative effects of an ongoing stressful event. Data from 1,925 U.S. Army soldiers deployed in support of Operation Iraqi Freedom (OIF) was used to examine whether BF would moderate the relationship between combat exposure and posttraumatic stress disorder (PTSD) and depression. Regression analyses revealed that BF was associated with lower levels of PTSD and depression. However, we found that BF during the combat deployment was found to moderate the combat exposure-PTSD relationship, such that the relationship was stronger when BF was low. Results are discussed in terms of BF being a form of meaning-based coping that may help soldiers adjust to the challenges of war.

Separate groups of participants listened to target speech sentences presented simultaneously with 0-to-3 competing sentences through four spatially-separated loudspeakers in two sound field test rooms having RT = 0.6 Sec (Site 1: N = 16) and RT = 0.4 sec (Site 2: N = 12). Speech recognition scores (SRSs) for the Synchronized Sentence Set (S(3)) test and subjective estimates of perceived task difficulty were recorded. Obtained results indicate that the change in room RT from 0.4 to 0.6 sec did not significantly influence SRSs in quiet or in the presence of one competing sentence. However, this small change in RT affected SRSs when 2 and 3 competing sentences were present, resulting in mean SRSs that were about 8-10% better in the room with RT = 0.4 sec. Perceived task difficulty ratings increased as the complexity of the task increased, with average ratings similar across test sites for each level of sentence competition. These results suggest that site-specific normative data must be collected for sound field rooms if clinicians would like to use two or more directional speech maskers during routine sound field testing.

TI The effects of 24-hour sleep deprivation on the exploration-exploitation trade-off SO BIOLOGICAL RHYTHM RESEARCH LA English DT Article DE sleep deprivation; exploration-exploitation; reasoning; decision making; resource acquisition; foraging ID ONE NIGHT; DECISIONS; TASK; PERFORMANCE AB Sleep deprivation has a complex set of neurological effects that go beyond a mere slowing of mental processes. While cognitive and perceptual impairments in sleep deprived individuals are widespread, some abilities remain intact. In an effort to characterize these effects, some have suggested an impairment of complex decision-making ability despite intact ability to follow simple rules. To examine this trade-off, 24-hour total sleep deprived individuals performed two versions of a resource acquisition foraging task, one in which exploration is optimal (to succeed, abandon low value, high saliency options) and another in which exploitation is optimal (to succeed, refrain from switching between options). Sleep deprived subjects exhibited decreased performance on the exploitation task compared to non-sleep deprived controls, yet both groups exhibited increased performance on the exploratory task. These results speak to previous neuropsychological work on cognitive control. C1 [Glass, Brian D.; Maddox, W.

However, implementing these models is often cost prohibitive due to intensive data-collection requirements and complex technical implementation. There is a growing need for a rapid, inexpensive method to project regional urban growth for the purposes of assessing environmental impacts and implementing long-term growth-management plans. We present the Regional Urban Growth (RUG) model, an extensible mechanism for assessing the relative attractiveness of a given location for urban growth within a region. This model estimates development attraction for every location in a rasterized landscape on the basis of proximity to development attractors, such as existing dense development, roads, highways, and natural amenities. RUG can be rapidly installed, parameterized, calibrated, and run on almost any several-county region within the USA. We implement the RUG model for a twelve-county region surrounding the Jordan Lake Reservoir, an impoundment of the Haw River Watershed (North Carolina, USA). This reservoir is experiencing major water-quality problems due to increased runoff from rapid urban growth. We demonstrate the RUG model by testing three scenarios that assume (1) 'business-as-usual' growth levels, (2) enforcement of state-mandated riparian buffer regulations, and (3) riparian buffer regulations augmented with forecast conservation measures. Our findings suggest that the RUG model can be useful not only for environmental assessments, stakeholder engagement, and regional planning purposes, but also for studying specific state and regional policy interventions on the direction and location of future growth pressure.

For spatial four-bar mechanisms, coupler motion can be replicated by moving the mechanism's moving axode over its fixed axode in a screw motion - a combination of simultaneous rotations and translations. This study presents a model to calculate the fixed and moving axodes of the revolute-revolute-spherical-spherical (RRSS) mechanism - one of the most basic spatial four-bar mechanisms. The axodes are useful in producing the contact surfaces for a cam system to replicate RRSS coupler motion. C1 [Shen, Qiong] ASCO Power Technol, Florham Pk, NJ 07932 USA.

TI Making the most of alarm signals: the adaptive value of individual discrimination in an alarm context SO BEHAVIORAL ECOLOGY LA English DT Article DE alarm call; alarm signal; individual discrimination; individual recognition; individuality; reliability ID RICHARDSONS GROUND-SQUIRRELS; SPERMOPHILUS-RICHARDSONII; ACOUSTIC STRUCTURE; VOCAL RECOGNITION; RANA-CATESBEIANA; RESPONSE URGENCY; AGE-DIFFERENCES; RHESUS-MONKEYS; GROUP MEMBERS; LIFE-HISTORY AB The value of individual discrimination is straightforward for many signal contexts, such as with contact or isolation calls, territorial marks, or status announcements. In contrast, the value of individual discrimination is less straightforward for alarm signals, and it is not yet known how or under what circumstances individual discrimination would be beneficial in an alarm context. One proposed mechanism is that receivers may discriminate individual signalers and respond differently based on the signaler's reliability, and that this may allow the receivers to optimize their antipredator behavior. To evaluate this mechanism, I constructed a dynamic model to test the fitness outcomes of 5 receiver response strategies under varying environmental, life history, and social conditions. The individual discrimination strategy yielded the highest fitness under the widest range of conditions, and the difference was substantial except in cases of very low predation pressure and high signaler accuracy. The adaptive value of individual discrimination of alarm signals may thus be a general phenomenon in nature and may provide evolutionary pressure for animals to increase their discrimination abilities. For species that use alarm signals nepotistically, the value of individual discrimination could provide selective pressure for the evolution of individual signatures in alarms and may help explain why the alarm signals of many species are so individualistic.

TI Adaptive stochastic disturbance accommodating control SO INTERNATIONAL JOURNAL OF CONTROL LA English DT Article DE disturbance accommodating control; stochastic adaptive control; Kalman filter; stochastic stability ID LINEAR-SYSTEMS; DESIGN AB This article presents a Kalman filter based adaptive disturbance accommodating stochastic control scheme for linear uncertain systems to minimise the adverse effects of both model uncertainties and external disturbances. Instead of dealing with system uncertainties and external disturbances separately, the disturbance accommodating control scheme lumps the overall effects of these errors in a to-be-determined model-error vector and then utilises a Kalman filter in the feedback loop for simultaneously estimating the system states and the model-error vector from noisy measurements. Since the model-error dynamics is unknown, the process noise covariance associated with the model-error dynamics is used to empirically tune the Kalman filter to yield accurate estimates. A rigorous stochastic stability analysis reveals a lower bound requirement on the assumed system process noise covariance to ensure the stability of the controlled system when the nominal control action on the true plant is unstable. An adaptive law is synthesised for the selection of stabilising system process noise covariance. Simulation results are presented where the proposed control scheme is implemented on a two degree-of-freedom helicopter. C1 [George, Jemin] USA, Res Lab, Adelphi, MD 20783 USA.

In some cases, however, phosphate treatment has been reported to increase lead concentrations in field water leaching tests. The present study evaluated the influence of phosphate (sodium phosphate, PO4(aq), or particulate hydroxyapatite, HA) and lead (lead nitrate, Pb(aq), or particulate lead oxide, PbO(s)) sources on the physical, chemical, and relative transport properties of their reaction products. Relative transport behavior of the product of each of the four possible combinations was investigated with settling columns assessing potential surface water transport and sand columns assessing potential ground water transport. Pyromorphite (HYP) was the only product formed when PO4(aq) and Pb(aq) were combined. The HYP formed under these conditions was the least mobile form of lead and phosphate examined in this work. Although additional products were formed when PO4(aq) was combined with PbO(s), lead transport was significantly reduced compared to the PbO control. On the other hand, HA was much less effective at controlling the transport of Pb(aq) in sand columns, particularly at low pH. In addition, the presence of HA increased the mobility of PbO at pH 7.2 relative to the control. It is recommended that the accepted practice of using HA in sandy firing range soils, under low to neutral pH conditions, be reconsidered.

Self-described principled participants (high scorers on the Integrity Scale) more strongly preferred principled-prototypic others over expedient ones and believed it possible to be more principled in one's beliefs (Study 1), preferred evaluators who regarded them as principled over expedient (Study 2), had friends who saw them as principled and paired up with friends who were themselves principled (Study 3). In contrast, expedient individuals did not display mirror-image reactions but saw merit in being both expedient and principled; they were accepting of any relevant feedback and partner preferences.

We provide an in-depth description of the interactions between these complex environmental conditions and behaviors of stream-dwelling salmonids during winter. Fisheries managers should be aware of the conditions that fish confront during winter in order to make appropriate management decisions. Diverse habitats, including deep pools with low water velocities, coarse rock substrate, and abundant cover, as well as side channels and backwaters, aid in the survival of overwintering fish. The inflow of relatively warm groundwater into the water column can be an important factor affecting winter habitat. Considering the length of winter and the vulnerability of fish during winter, a broad understanding of winter ice process and their effects on stream dwelling fish can aid in the preservation and improvement of winter habitats.

A boron containing monomer, specifically phenylboronic acid (PBA), and imide forming monomers, specifically aromatic dianhydrides 4,4'-oxydiphthalicanhydride (Oxy) and 1,1,4,4-tetracarboxylicphenyldianhydride (DAH), were employed to make terpolymers with propylamino-terminated polydimethylsiloxane (A12-PDMS). The terpolymer synthesis was carried out using various PBA: Oxy and PBA: DAH compositions ranging from 0 : 1 to 1 : 0 mole ratios. The thermal and flame retardant properties of the novel polymers were investigated. Intermediate ratios of both PBA: Oxy and PBA: DAH resulted in optimal thermal stability and flame retardancy. These novel terpolymers are promising candidates as environmentally-safe, non-halogenated alternatives to traditional flame retardant polymers.

The results aid further development and adoption for military applications of cold-weather wool blend fabrics that are more flame resistant and warmer than 100% polyester garments. Two types of bi-sided fabrics were tested: 1) thin knit fabrics designed to be worn next to the skin, usually as undergarments, and 2) thick fleece mid and outer layers with 100% wool on the outer face and 100 % polyester on the inner surface. The following issues were addressed: 1) the effect of wool content on the knit fabrics, 2) the effect of fabric orientation on both the knit and the fleece fabrics, and 3) the effect of durable water-repellent treatment on the fleece fabrics.

TI Dynamic impact indentation of hydrated biological tissues and tissue surrogate gels SO PHILOSOPHICAL MAGAZINE LA English DT Article DE tissue surrogate; impact indentation; energy dissipation; liver; heart ID SOFT HUMAN TISSUES; VISCOELASTIC PROPERTIES; MECHANICAL-PROPERTIES; TRIBLOCK COPOLYMERS; ARTICULAR-CARTILAGE; ENERGY-DISSIPATION; LIVER-TISSUE; NANOINDENTATION; COMPRESSION; SIMULATION AB For both materials engineering research and applied biomedicine, a growing need exists to quantify mechanical behaviour of tissues under defined hydration and loading conditions. In particular, characterisation under dynamic contact-loading conditions can enable quantitative predictions of deformation due to high rate 'impact' events typical of industrial accidents and ballistic insults. The impact indentation responses were examined of both hydrated tissues and candidate tissue surrogate materials. The goals of this work were to determine the mechanical response of fully hydrated soft tissues under defined dynamic loading conditions, and to identify design principles by which synthetic, air-stable polymers could mimic those responses. Soft tissues from two organs (liver and heart), a commercially available tissue surrogate gel (Perma-Gel (TM)) and three styrenic block copolymer gels were investigated. Impact indentation enabled quantification of resistance to penetration and energy dissipative constants under the rates and energy densities of interest for tissue surrogate applications. These analyses indicated that the energy dissipation capacity under dynamic impact increased with increasing diblock concentration in the styrenic gels. Under the impact rates employed (2 mm/s to 20 mm/s, corresponding to approximate strain energy densities from 0.4 kJ/m(3) to 20 kJ/m(3)), the energy dissipation capacities of fully hydrated soft tissues were ultimately well matched by a 50/50 triblock/diblock composition that is stable in ambient environments. More generally, the methodologies detailed here facilitate further optimisation of impact energy dissipation capacity of polymer-based tissue surrogate materials, either in air or in fluids.

TI MULTI-PASS RUTTING STUDY FOR TURNING WHEELED AND TRACKED VEHICLES SO TRANSACTIONS OF THE ASABE LA English DT Article DE Multi-pass; Rut; Tracked and wheeled vehicles; Turning ID SOIL COMPACTION; TERRAIN; PREDICTION; IMPACTS AB In this article, the effects of multiple vehicle passes and turning maneuvers by wheeled and tracked vehicles on rutting are discussed. Field tests were conducted at Fort Riley in August 2008 using an M1A1 combat tank, an armored personnel carrier (APC), a heavy expanded mobility tactical truck (HEMTT), and a high-mobility multi-purpose wheeled vehicle (HMMWV). These vehicles were operated in spiral patterns to evaluate the effect of different turning radii. Along each spiral in the same rut, each vehicle was driven up to eight passes. A vehicle tracking system (VTS) mounted on each vehicle utilized a Global Positioning System (GPS) to determine the vehicle dynamics (velocity and turning radius). As expected, compared to a single pass, results show that soil deformation and compaction increased with the increase in the number of passes. Multiple passes and turning maneuvers by vehicles resulted in rut depth increases in the range of 65% to 548%. The results of this study also confirmed that the multi-pass coefficient (alpha = 2) is appropriate to predict multi-pass rut depth for turning vehicles in loose soils.

TI Differential Amplifier Sensor Architecture for Increased Sensor Selectivity SO IEEE TRANSACTIONS ON NANOTECHNOLOGY LA English DT Article DE Carbon nanotubes (CNTs); chemical analysis; chemical transducers; differential amplifiers; FETs ID CARBON NANOTUBE TRANSISTORS; GAS AB The use of a differential amplifier sensor architecture has been investigated as a route to improved sensor selectivity. Carbon nanotube FETs (CNTFETs) are used as both the transistors in a differential amplifier as well as chemical-sensing elements. Chemical functionalization of the CNTFETs can result in selective sensing. However, functionalized sensors are still likely susceptible to many undesired nonselective sensing events. By functionalizing two FETs differently, one FET can be tailored to selectively sense the analyte, and the other can be used as a reference to compensate for a wide range of interfering signals when the two FET outputs are subtracted. In this way, many interfering events can be discriminated against to yield robust and selective sensing in complex and dynamic environments. Proof of concept experiments showing the utility of background subtraction in software (calculated differential amplifier output) and hardware (using a breadboarded differential amplifier) are shown.

In this article, we report gold-nanoparticle-based two-photon light-scattering (TPS) assay, for the label-free detection of arsenic and Salmonella bacteria separately, with excellent detection limit and selectivity over other analytes. Our experimental results show that arsenic can be detected quickly and accurately without any tagging, in 100-ppt level with excellent discrimination against other heavy metals. We have demonstrated that our TPS assay is capable of measuring the amount of arsenic in Bangladesh, West Bengal, and Nevada well water as well as in Mississippi river water. We have also shown that gold-nanoparticle-based TPS assay are capable for label-free detection of Salmonella typhimurium (S. typhimurium) with excellent detection limit (103 bacteria/mL) and high selectivity over other pathogens. The mechanism of TPS assay working principle has been discussed. Our results demonstrate the potential for a broad application of nanotechnology in practical defense applications.

In this paper, we report molecular dynamics simulations of pressure-driven flow through a silica nanochannel and characterize, with atomic resolution, adsorption of a model protein to the surface of the nanochannel. Although the simulated adsorption of the proteins was found to be nonspecific, it had a dramatic effect on the rate of the protein transport. To determine the relative strength of the protein-silica interactions in different adsorbed states, we simulated flow-induced desorption of the proteins from the silica surface. Our analysis of the protein conformations in the adsorbed states did not reveal any simple dependence of the adsorption strength on the size and composition of the protein-silica contact, suggesting that the heterogeneity of the silica surface may be an important factor.

TI Axial-Weld Land Buckling in Compression-Loaded Orthogrid Cylinders SO JOURNAL OF SPACECRAFT AND ROCKETS LA English DT Article AB Large stiffened cylinders used in launch vehicles, such as the space shuttle external tank, are manufactured by welding curved panels into complete barrels. The effects of the axial-weld lands between the panels on the buckling strength of unpressurized cylinders are studied, along with the interaction between the acreage stiffener arrangement and the weld land geometry. The relatively thick, unstiffened axial-weld lands are shown to significantly reduce the buckling load when the cylinder is loaded in uniform axial compression, and a relationship between the reduction in buckling load and the orthogrid design is shown. Reducing the width of the weld lands is shown to be the most effective means of minimizing the reduction in buckling strength, and thicker weld lands are shown to not always increase their buckling resistance. Detailed models with individual stiffeners modeled as beams are used to show that the weld land buckling phenomenon is very sensitive to the specific location and geometry of stiffeners near the axial-weld lands. It is also shown that the buckling strength can be significantly improved by ensuring that the distance between the weld land and the adjacent longitudinal stiffener is minimized.

TI Computational analysis and experimental validation of the friction-stir welding behaviour of Ti-6Al-4V SO PROCEEDINGS OF THE INSTITUTION OF MECHANICAL ENGINEERS PART B-JOURNAL OF ENGINEERING MANUFACTURE LA English DT Article DE friction-stir welding; Ti-6Al-4V; finite element analysis; weld microstructure/properties prediction ID 6061-T6 ALUMINUM; MICROSTRUCTURE; EVOLUTION; TITANIUM; ALLOYS; GROWTH; AA5083 AB A fully coupled thermomechanical finite element analysis of the friction-stir welding (FSW) process developed in the authors' previous work is combined with the basic physical metallurgy of Ti-6Al-4V to predict/assess the structural response of FSW joints. A close examination of the experimental results reported in the open literature reveals that in most cases the heat-affected zone (HAZ) of the weld possesses the most inferior properties and tends to control the overall structural performance of the weld. Taking this observation into account, a microstructure evolution model is developed and parameterized for the Ti-6Al-4V material residing in the HAZ. Specifically, this model addresses the problem of temporal evolution of the globular a-phase particles located within prior beta-phase grains (the dominant microstructural parameter in the HAZ) during the FSW process. Next this model is combined with the well-established property versus microstructure correlations in Ti-6Al-4V in order to predict the overall structural performance of the weld. The results obtained are found to be in reasonably good agreement with their experimental counterparts, suggesting that the present computational approach may be used to guide the selection of FSW process parameters in order to optimize the structural performance of FSW joints (at least while they are controlled by the HAZ-material microstructure/properties).

In view of the complex nature of the South Florida water resources system, regional-scale (system-wide) hydrologic models have been developed and used extensively for the development of the Comprehensive Everglades Restoration Plan. In addition, numerous subregional-scale hydrologic and hydrodynamic models have been developed and are being used for evaluating project-scale water management plans associated with urban, agricultural, and inland costal ecosystems. The authors provide a comprehensive summary of models of all scales, as well as the next generation models under development to meet the future needs of ecosystem restoration efforts in South Florida. The multiagency efforts to develop and apply models have allowed the agencies to understand the complex hydrologic interactions, quantify appropriate performance measures, and use new technologies in simulation algorithms, software development, and GIS/database techniques to meet the future modeling needs of the ecosystem restoration programs.

The authors used the Everglades Landscape Model and Multi-Criteria Decision Analysis to explore the effect of simulated ecosystem performance, risk preferences, and criteria weights on the ranking of three alternatives to restoring overland sheet flow in the Everglades. The ecological model outputs included both hydrologic and water quality criteria. Results were scored in the decision analysis framework, highlighting the trade-offs between hydrologic restoration and water quality constraints. Given equal weighting of performance measures, the alternative with more homogenous sheet flow was preferred over other alternatives, despite evidence of some localized eutrophication risk.

An experimental approach has been taken to determine the burst time relative to the discharge current, voltage, resistance, and power waveforms. A microphone transducer was employed to detect the time of burst from the sound produced by the bursting of the film and was compared to the calculated burst times. A theoretical discussion on the energy needed to melt and vaporize the film is also presented and compared to the experimental results.

Kobayashi, Nobuhisa TI Stone Armor Damage Initiation and Progression Based on the Maximum Wave Momentum Flux SO JOURNAL OF COASTAL RESEARCH LA English DT Article DE Breakwater; revetment; stone; armor stability; armor damage ID RUBBLE-MOUND BREAKWATERS; HEIGHT PARAMETER; STABILITY AB The armor layer on the sea side of a rubble structure must be designed to protect against incident waves during storms. Formulas for armor stability and damage progression have been developed and are widely used for practical applications. However, none of the formulas accounts for the water depth at the toe of the structure explicitly. An alternative approach based on the maximum wave momentum flux at the toe of the structure is proposed in this article. Equations for sizing stable armor stone for constant incident waves and water level are proposed and calibrated using available data. Equations are also developed for determining damage progression in a life-cycle analysis involving varying wave and water level characteristics. The developed equations are calibrated using the damage progression tests conducted previously by the authors and verified using an additional 10 tests conducted for this article.

While restoration timeframes are dependent on numerous variables, a primary controlling factor is the level of pre-planning and decision-making completed prior to chemical terrorist release. What follows is the first of a two-part analysis identifying key considerations, critical information, and decision criteria to facilitate post-attack and post-decontamination consequence management activities. A conceptual site model and human health-based exposure guidelines are developed and reported as an aid to site-specific pre-planning in the current absence of U.S. state or Federal values designated as compound-specific remediation or re-entry concentrations, and to safely expedite facility recovery to full operational status. Chemicals of concern include chemical warfare nerve and vesicant agents and the toxic industrial compounds phosgene, hydrogen cyanide, and cyanogen chloride. This work has been performed as a national case study conducted in partnership with the Los Angeles International Airport and The Bradley International Terminal. All recommended guidelines have been selected for consistency with airport scenario release parameters of a one-time, short-duration, finite airborne release from a single source followed by compound-specific decontamination.

TI Reanalysis of turbulence effects on short-exposure passive imaging SO OPTICAL ENGINEERING LA English DT Article DE atmospheric optics; atmospheric turbulence; image formation theory; modulation transfer function; resolution ID MODULATION TRANSFER-FUNCTION; POINT-SPREAD FUNCTION; STATISTICS AB The standard method for modeling the atmospheric short-exposure modulation transfer function (MTF) is due to Fried. This method involves evaluating the impact of amplitude and phase modulations of the propagating wavefront after the removal of the mean wavefront tilt. This tilt is determined by a least-squares analysis. We retain a term involving the correlation between tilt-corrected phase and computed tilt vector that was formerly assumed to be zero. Inclusion of this term yields a new turbulence-strength-dependent effect that degrades performance at high integrated turbulence levels and also predicts super-resolution effects at lower integrated turbulence levels. An analytical approximation is derived from this analysis that describes the new MTF model as a function of three dimensionless parameters related to the angular frequency, system aperture diameter, and integrated turbulence strength.

This policy included the provision of a Menu of Incentives Program targeting officers in year groups 1999-2005. This study details the captain attrition problem, evaluates literature regarding retention options, analyzes the efficacy of the Army's interventions by branch and by year group, and draws conclusions regarding future incentives. Methods used include chi-square and odds ratios analysis. Results reflect high acceptance rates for year groups 1999-2003; however, officers in these year groups may have remained in the service without any additional incentives because they were logically beyond the initial decision point. Findings suggest that seniority, skill, and adequate incentive pay are important considerations for future incentive programs. C1 [Silvernail, Teresa S.] USA, Washington, DC USA.

The model components are applied to an identical, unstructured mesh; share parallel computing infrastructure; and run sequentially in time. Wind speeds, water levels, currents and radiation stress gradients are vertex-based, and therefore can be passed through memory or cache to each model component. Parallel simulations based on domain decomposition utilize identical sub-meshes, and the communication is highly localized. Inter-model communication is intra-core, while intra-model communication is inter-core but is local and efficient because it is solely on adjacent sub-mesh edges. The resulting integrated SWAN +ADCIRC system is highly scalable and allows for localized increases in resolution without the complexity or cost of nested meshes or global interpolation between heterogeneous meshes. Hurricane waves and storm surge are validated for Hurricanes Katrina and Rita, demonstrating the importance of inclusion of the wave-circulation interactions, and efficient performance is demonstrated to 3062 computational cores.

The injection velocity is provided by a 26-mm-diameter conventional propellant gun. A plasma armature is assumed for the railgun. A capacitor-based pulsed-power supply, located at Barricade C, Aberdeen Proving Ground, MD, is assumed to provide the electrical energy for boosting the velocity to 2.5 km/s. Various scenarios are examined with respect to electrical pulse shape, the effect on stored electrical energy, and its distribution in the railgun. Three types of comparisons are used to illustrate the effect of injection velocity on stored electrical energy: 1) efficiency; 2) peak loads; and 3) energy storage. Examples for each category are discussed, illustrating complementary areas for propellant gun and railgun operation. Results are promising; however, the initial velocity must be considered in detailed simulations in order for any advantages to be realized.

TI An investigation of infrared deicing through experimentation SO COLD REGIONS SCIENCE AND TECHNOLOGY LA English DT Article DE Infrared; Ice; Deicing; Melt; Transmission; Conduction AB Traditional deicing of parked aircraft with Aircraft Deicing Fluids (ADF), while effective, has a significant environmental and cost impact, with an estimated 75% of the cost of using ADF attributed to permitting, storage and disposal. In addition, traditional ADF deicing fluids are harmful to helicopter components, and cannot housed for deicing helicopters. Infrared energy is a potential alternative to ADF. However, excessive infrared heating of the laminated composite helicopter blades during deicing could result in blade failure. This report investigates infrared deicing physical processes through experimentation and found excessive infrared heating of the ice substrate is only an issue when the ice thickness is less than 1 mm. In addition, this report evaluates IR heater designs for optimizing deicing and recommends future development that may allow hybrid infrared systems to reduce ADF use. Published by Elsevier B.V.

TI Ice protection of offshore platforms SO COLD REGIONS SCIENCE AND TECHNOLOGY LA English DT Article DE Offshore platform; Atmospheric icing; Superstructure icing; Ice protection; Safety; Arctic ID ACCRETION AB Climate change-induced reduction in the extent and duration of sea ice cover, as well as an increase in energy demands, has caused renewed interest in exploring and drilling for oil in Arctic waters. Superstructure icing from sea spray and atmospheric icing in the Arctic may impact offshore platform operations. Though icing has not caused the loss of an offshore platform, it can reduce safety, operational tempo, and productivity. Historically, many ice protection technologies were tested on offshore platforms with little success. However, new technologies and modern versions of old technologies used successfully in aviation, the electric power industry, and ground transportation systems, may be adapted to an offshore environment. This paper provides a framework for assessing the relative threat of ice accumulation types, such as superstructure ice, glaze, rime, frost, and snow, to the safety of platform functions. A review of ice protection strategies for functional platform areas is also provided. Published by Elsevier B.V. C1 USA, Cold Reg Res & Engn Lab, Engineer Res & Dev Ctr, Hanover, NH 03755 USA.

Both the theoretical and the experimental investigations of the device were performed. The measured value of optical transmission of the antireflection-coated crystal was 70%, corresponding to a relatively low optical absorption coefficient alpha <= 0.3 cm(-1). Detailed characterization of the device was carried out at 10.6 mu m using a CO(2) laser and the diffraction efficiency of the deflector along each of two orthogonal directions was found to be 50-60% at 1.0-2.0 W drive power. Here, we present results from both the experimental and the theoretical investigations of the deflector.

Our proposed adaptive intrusion detection technique is based on majority voting by nodes in a geographical region to cope with collusion of compromised nodes, with each node preloaded with anomaly-based or misuse-based intrusion detection techniques to diagnose compromised nodes in the same region. When given a set of parameter values characterizing operational and environmental conditions, we identify the optimal intrusion detection rate and the optimal regional area size under which the mean time to security failure of the system is maximized and/or the total communication cost is minimized for GCSs in MANET environments. The tradeoff analysis in performance versus security is useful in identifying and dynamically applying optimal settings to maximize the system lifetime for scalable mobile group applications while satisfying application-specific performance requirements.

The pullout test program involved four types of steel fibers, eight compressive strengths of VHSC matrixes, and two normal concrete strengths. Test results have shown that pullout behavior of different steel fiber reinforced VHSC composites is influenced by the matrix strength and fiber end condition (smooth, flat end, or hooked). Results reveal that both maximum pull-out load and total pullout energy increases as matrix strength increases for all deformed fibers that did not rupture. The test results also indicated that the increase in total pullout energy is more significant than that in peak load. (C) 2010 Elsevier Ltd. All rights reserved.

The design principles of our algorithm, netCSI, are motivated by the fact that failures are geographically clustered in such cases. We address the challenge of determining faults with incomplete symptom information due to a limited number of reporting nodes in the network. netCSI consists of two parts: hypotheses generation algorithm, and ranking algorithm. When constructing the hypotheses list of potential causes, we make novel use of the positive and negative symptoms to improve the precision of the results. The ranking algorithm is based on conditional failure probability models that account for the geographic correlation of the network objects in clustered failures. We evaluate the performance of netCSI for networks with both random and realistic topologies. We compare the performance of netCSI with an existing fault diagnosis algorithm, MAX-COVERAGE, and achieve an average gain of 128% in accuracy for realistic topologies.

Recently, the trend has been to use virtualization technology, which facilitates hosting of multiple distributed systems with minimum infrastructure cost via sharing of computational and memory resources among multiple instances, and allows dynamic creation of even bigger clusters. An effective monitoring technique should not only be fine grained with respect to the measured variables, but also should be able to provide a high level overview of the distributed systems to the administrator of all variables that can affect the QoS requirements. At the same time, the technique should not add performance burden to the system. Finally, it should be integrated with a control methodology that manages performance of the enterprise system. In this paper, a systematic distributed event based (DEB) performance monitoring approach is presented for distributed systems by measuring system variables (physical/virtual CPU utilization and memory utilization), application variables (application queue size, queue waiting time, and service time), and performance variables (response time, throughput, and power consumption) accurately with minimum latency at a specified rate. Furthermore, we have shown that proposed monitoring approach can be utilized to provide input to an application monitoring utility to understand the underlying performance model of the system for a successful on-line control of the distributed systems for achieving predefined QoS parameters.

The question naturally arises: what is the cost in fidelity incurred by distributing the simulation across Internet links? The degree to which an Internet-distributed simulation loses fidelity relative to a single-location HIL setup is referred to as distortion in this paper. Various factors affect distortion, including the Internet's delay, jitter, and loss, as studied extensively in the literature. Additional considerations, however, such as the coupling points, i.e., the particular points at which the system model shall be divided to enable distribution across the Internet, also affect distortion. The aim of this paper is to turn coupling point selection into a design decision that can be used to minimize distortion. To quantify distortion, a frequency-domain metric is proposed using a linear systems framework. This metric is then used to analyze how the choice of the coupling point affects distortion, and it is also linked to a sensitivity function, which is easier to interpret physically. This analysis can be used in an ID-HIL setup to pick a coupling point that gives minimal distortion, and is the first step towards analyzing the trade-off between stability robustness and transparency in an ID-HIL system.

This paper presents a symbolic dynamics-based method of data-driven pattern classification by extracting the embedded information from noise-contaminated sensor time series. In the proposed method, the wavelet transforms of sensor data are partitioned to construct symbol sequences. Subsequently, the relevant information is extracted via construction of probabilistic finite state automata (PFSA) from symbol sequences. The patterns are derived from individual PFSA and are subsequently classified to make decisions on target classification. The proposed method has been validated on field data from seismic sensors to monitor infiltration of humans, light vehicles, and animals. The results of pattern classification demonstrate low false-alarm/missed-detection rate in target detection and high rate of correct target classification.

The study attempts to determine if the teaching technique increases conceptual understanding of foundational engineering topics and therefore increases the performance on the conceptual portion of exams in four separate courses (n = 131). It also examines the effect of such frequent testing on the attitudes of the students through the use of surveys. In sum, no conclusion could be made about the method's ability to raise exam scores, but it did not negatively impact student attitudes about the classes. The motivation behind using the technique is reviewed along with relevant literature, and administrative guidance is also provided for those who wish to try the technique themselves at both small and large schools.

Most undergraduate students form an early belief that these two aspects of thermal-fluid science and engineering are as far removed from each other as cats are from dogs. It is not until the senior year or even into their graduate school experience that the student begins to understand and appreciate the underlying physical conservation laws upon which both of these disciplines are based. As a result of mechanical engineering curriculum revision at the United States Military Academy at West Point, New York, separate courses in thermodynamics and fluid mechanics were integrated into a two-course sequence, Thermal-Fluid Systems I and II, in academic year 2005-2006. While succeeding in developing the two disciplines together under one overarching set of physical laws, there was still an issue with finding a suitable textbook. After four years of instruction using available textbooks from publishers, the mechanical engineering faculty developed a text tailored specifically to the integrated two-course sequence. The experience in writing a text that integrates concepts in thermodynamics and fluid mechanics highlights the need for consistency between the two disciplines. Issues identified include logical organization of topics, selection of appropriate variables, consistent use of sign convention throughout all topics, recognition of various forms of the same fundamental principle, and definition of performance parameters. This paper explores these issues and how they were addressed for integrated instruction of thermodynamics and fluid mechanics. Feedback gleaned from student surveys and faculty comments with regard to the initial implementation of the text was used to modify the text and examples. Performance feedback and newly identified issues are presented. C1 [Crawford, Bobby G.; Boettner, Daisie D.] US Mil Acad, West Point, NY USA.

GP ASEE TI Undergraduate Capstone Design: Inductively Enhanced SO 2011 ASEE ANNUAL CONFERENCE & EXPOSITION SE ASEE Annual Conference & Exposition LA English DT Proceedings Paper CT ASEE Annual Conference and Exposition CY JUN 26-29, 2011 CL Vancouver, CANADA SP ASEE AB The Department of Civil and Mechanical Engineering at the United States Military Academy at West Point, New York requires its graduates to complete an integrative, year-long capstone design during their senior year. One of the capstone projects available to the mechanical engineering students in the department's aerospace sub-discipline requires the design, construction, testing, and demonstration of a small, highly autonomous Uninhabited Aerial Vehicle (UAV) for a Department of Defense client. This particular project was added to the list of available capstone options in the fall of 2005. This paper briefly describes the motivation behind the addition of the UAV capstone design option, resources that were required to start the program, and selected budget data collected during the second and third years of the capstone design. Teams in the first year of the project were limited to a budget of $9,000 each and experienced mixed results during final flight demonstrations. Second year budgets were increased to $12,000 for each team based on feedback from the first-year experience. Performance at flight demonstrations was markedly improved in the second year. Lessons learned from the first two years were used to significantly modify the program in the third and subsequent years. Students began the design with very little practical, hands-on experience with small aircraft and the associated subsystems. Faculty members spent a significant amount of time researching learning methods and discussing potential modifications to the project structure that would result in a rapid acquisition of foundational knowledge by the students. In particular, the third year of the program was modified to incorporate an inductive learning experience as part of the project. Students began by building and testing an off-the-shelf, Remotely-Controlled (RC) airplane; modifying it to operate with an off-the-shelf autopilot; and conducting bench and flight testing of the aircraft and its components. The intent of this rapid, three week experience was to develop a cognitive schema that the students could draw upon as they executed the design process and created their original UAVs. This approach, its benefits, and lessons learned are detailed. C1 [Crawford, Bobby G.] US Mil Acad, Mech Engn Program, Dept Civil & Mech Engn, West Point, NY 10996 USA.

As much of the prior research has applied multiple identities as the theoretical framework, the current study also applied this approach towards its goals of understanding the commonalities and differences among students within these two groups. This research aims to fill a gap in the collective knowledge as to the factors that contribute to the development of a student's professional identity and more specifically identification with engineering. We hypothesized that students associated with military routines would have a stronger professional identification within their chosen academic major than students not associated with these routines. The results of this work can be used to guide administrative / curricular structures for engineering education to support students' identification with engineering, which is believed to increase a student's likelihood for educational and professional persistence post-graduation. Semi-structured interviews were performed at three universities to gain a better understanding of how students develop their professional identities. Specifically, the student participants were from a cross-section of levels toward degree completion and were from two departments of engineering (civil and mechanical), as well as history for reference. Two universities served as the main research sites; the first a military university in the northeastern United States and the second a private university in the midwestern region. The third university was a large public university in the southeastern United States that served as an expansion of the study. The results of our study show some distinct similarities and differences in the identity development of students. Identifying as a family member or with a geographic region seemed universal, and there was a more distinct professional identity for engineering students than history students. One clear difference was the approach to how students selected their institution of higher education. Also, it was clear that organized activities that contributed to a shared / common developmental experience was useful in identity development. These initial findings spark many more questions relating to identity development, which could be further explored looking at student's development over time.

As much of the prior research has applied multiple identities as the theoretical framework, the current study also applied this approach towards its goals of understanding the commonalities and differences among students within these two groups. This research aims to fill a gap in the collective knowledge as to the factors that contribute to the development of a student's professional identity and more specifically identification with engineering. We hypothesized that students associated with military routines would have a stronger professional identification within their chosen academic major than students not associated with these routines. The results of this work can be used to guide administrative / curricular structures for engineering education to support students' identification with engineering, which is believed to increase a student's likelihood for educational and professional persistence post-graduation. Semi-structured interviews were performed at three universities to gain a better understanding of how students develop their professional identities. Specifically, the student participants were from a cross-section of levels toward degree completion and were from two departments of engineering (civil and mechanical), as well as history for reference. Two universities served as the main research sites; the first a military university in the northeastern United States and the second a private university in the mid-western region. The third university was a large public university in the southeastern United States that served as an expansion of the study. The results of our study show some distinct similarities and differences in the identity development of students. Identifying as a family member or with a geographic region seemed universal, and there was a more distinct professional identity for engineering students than history students. One clear difference was the approach to how students selected their institution of higher education. Also, it was clear that organized activities that contributed to a shared / common developmental experience was useful in identity development. These initial findings spark many more questions relating to identity development, which could be further explored looking at student's development over time.

Students enrolled in introductory microbiology courses can have difficultly visualizing the physical growth of bacteria, the stoichiometric ratios of substrate consumption, and the results of metabolic processes that produce end products. Methanotrophic bacteria can be used as a model, allowing students in an experimental laboratory class to understand microbiological fundamentals. Methanotrophs have been well studied and many strains are available for purchase through American Type Culture Collection (ATCC) and other culture collection services. Methanotrophs are also ubiquitous in nature and can be isolated from many different environments, including soils and aqueous sediments. Additionally, methanotrophs possess a relatively simple and easily understandable metabolic pathway, consuming methane (electron donor) and oxygen (electron acceptor) as their primary substrates, and producing carbon dioxide and water as end products. The objective of this study was to develop a simple experiment that clearly shows students the concepts of microbial growth, and the stoichiometry associated with substrate consumption, using simple techniques with a readily available source of bacteria, i.e., methanotrophs. The laboratory study is conducted as follows: in sterilized serum bottles, methanotrophic bacteria in the exponential growth phase are inoculated in a Milli-Q water-based medium containing nitrate, other key nutrients (P, K, Na, Mg, Ca, etc.), and selected trace metals. The primary substrates, methane and oxygen, are then introduced and each bottle is placed on a shaker-table for incubation. Gas samples are periodically withdrawn from the headspace of each bottle and manually injected into a gas chromatograph to measure the concentrations of methane, oxygen, and carbon dioxide. This allows students to monitor the amount of substrates consumed and the amount of end product produced at different time points. Students can also track microbial growth by measuring the increase in turbidity of the medium via changes in optical density (OD). Results of the substrate consumption and carbon dioxide production are then plotted in a spreadsheet program (e.g., Excel). Typical results clearly depict the different rates of substrate consumption for oxygen and methane, and the rate of carbon dioxide production. This unique approach allows students to see firsthand the stoichiometry of the chemical reactions associated with the metabolism of metanotrophs. The results also clearly depict the microbial growth concepts of lag, exponential growth, and, if the experiment is continued long enough, microbial death. This experiment has been successfully conducted by both graduate and undergraduate students with several different genuses of methanotrophic bacteria including Methylobacter, Methylonsinus, and Methylocystis, indicating that any genus of the methanotroph family can be successfully grown under these conditions. After using this approach, students will have a better understanding of microbial growth kinetics and the stoichiometry associated with the chemical reactions in the methanotrophic metabolic pathway, while gaining additional relevant lab experience.

Fundamentally, distance learning encompasses students participating in a class without being physically present; this includes not only remote campuses, where the communication infrastructure is likely to be robust, but also students studying on exchange programs either domestically or abroad. Specifically at the Civil and Mechanical Engineering Department at the United States Military Academy (USMA), the study abroad program is trending towards a more robust program to send our students abroad. In the past five academic semesters, we have sent 370 students to 35 universities around the globe. As the program continues in its development, its popularity among the students continues to grow. Given the growth in demand for this program at USMA and elsewhere, the Department of Civil and Mechanical Engineering at USMA has been carefully examining how to best deliver quality instruction to these students. The fundamental teaching model in our Department is well-expressed in the Excellence in Civil Engineering Education (ExCEEd) program, sponsored by the American Society of Civil Engineers (ASCE). The model includes six main elements for developing an effective learning environment: structured organization, engaging presentation, enthusiasm, positive rapport with students, frequent assessment of student learning, and appropriate use of technology. The primary question associated with distance learning is, "Can the ExCEEd teaching model work when the student isn't physically present?" The author's primary interest in this paper is to look closely at non-verbal communication as it relates to the ExCEEd teaching model and distance learning. The authors are most interested in non-verbal communication because it is related to three of the six main elements in ExCEEd teaching model: engaging presentation, enthusiasm, and positive rapport with students. Additionally, the nature of distance learning will necessitate and evaluation of how a fourth element, the appropriate use of technology, is applied to various methods of teaching a distance learning course. Further, non-verbal communication, as represented by facial expressions and body language, can be 65% of the teacher's effectiveness in delivering a message. Given these circumstances, it is important to assess the impact of various distance learning environments on a teacher's ability to express non-verbal content such that the ExCEEd teaching model is still effective. A case study approach will be used to illustrate and examine challenges in this area and recommendations will be presented rely on the body of knowledge of non-verbal communications, the ExCEEd teaching model, and the realities of distance learning.

The literature is filled with methods for achieving this goal. Most approaches are based on various learning theories that include appealing to multiple learning styles, increasing the student's emotional involvement with the material, and increasing student-faculty rapport and interaction. Many teaching techniques are designed with more than one of these principles in mind. This paper presents a technique, termed the Mystery Aircraft, that is designed to leverage multiple learning theories that increase student interest and retention of the material covered in two sequential aeronautical engineering classes. This is accomplished through the use of many visual examples of actual production and experimental aircraft. Additional discussion on the advantages of the Mystery Aircraft technique briefly cover topics such as applying the Dual Coded Theory of Redundancy and Reinforcement for cognitive learning, enhancing student cultural literacy within the field of aeronautical engineering, and support of institutional program outcomes and ABET criterion. The effectiveness of the technique in capturing students' attention, generating interest, and improving motivation is assessed through the use of student mid-course and course-end surveys. A listing of the aircraft examples and their associated topics is also presented in the appendix. C1 [Rowland, Matthew; Bluman, James E.] US Mil Acad, West Point, NY USA.

This is a challenge intensified by our burgeoning aging population, the obesity epidemic, and our aging healthcare workforce. During manual patient handling, the predominant risk of staff injury is excessive back and shoulder loading. A mobile robotic nurse assistant (RoNA) is highly desired to enhance the efficacy and quality of care that nurses and their paraprofessional staff can provide. Such an assistant could improve a nurse's working conditions by off-loading some of his or her most physically demanding duties, thereby reducing the potential for self-injury or injury to the patient. Hstar Technologies is developing a revolutionary RoNA system that provides physical assistance to nurses in a hospital ward. The design of RoNA is a safe and robust system that works effectively in a hospital environment under direct and telepresence control by a nurse or physician. RoNA has a humanoid design featuring bimanual dexterous manipulators that employ a series-elastic-actuation (SEA) system. These electric actuators provide manipulator compliance, safety, flexibility and the strength to lift patients weighing up to 300lbs. RoNA also features an innovative humanoid upper torso, a unique mobile platform with holonomic drive and posture stability enhancement, intelligent navigation control with 3D sensing and perception capability, an intuitive and innovative human-robot interaction control interface, and a highly integrated plan for healthcare system assembly. We anticipate that robotic maneuvering assistants would increase job satisfaction, reduce lifting-related injuries, and extend the years of effective service nurses could render in hospitals. These effects would reduce hospital costs and ameliorate problems posed by the shortage of nursing staff.

Identifying and integrating geographic features is a challenging task since many of their spatial and non-spatial properties are described in different sources. We tackle this expansion problem by defining semantic footprints as a measure of similarity among features. Furthermore, we propose three quantifiers of semantic similarity: spatial, dimensional, and ontological affinity. We show how these measures dilute, concentrate, harden, or concede the feature space, and provide useful insights into the semantic relationships of the spatial entities. Experiments demonstrate the effectiveness of our approach in semantically associating the most appropriate spatial features.

A bandwidth of 10% at 1.93 GHz is achieved. The simulated gain is greater than 6.1 dB and efficiency is 90%. Few EBG cells used in the present design reduce the overall size of the antenna structure.

A self-breakdown switch is used to discharge the antenna after charging it to the breakdown voltage of the switch. The antenna resonates at its quarter wavelength. In many high applications it is advantageous to: reduce the size of such source for a given resonance frequency, and increase the number of the radiated cycles after each switch closure. In the paper, we propose a new design for a conical helix antenna that help in achieving these two goals. Numerical simulations are used to compare the radiated far-field from our new design to those from conical helix and biconical designs. C1 [Armanious, M.; Tyo, J. S.; Keller, S.

Conventional radio transmitters have a narrow bandwidth, primarily limited by the bandwidth of the impedance matching network between the power amplifier and transmit antenna. The Directly-Driven Antenna (DDA) architecture has the potential to eliminate this limitation, as without the frequency constraints imposed by the conjugate impedance matching network, it is possible to couple power to a transmit antenna efficiently across a very wide bandwidth. Previous work demonstrates that the DDA architecture can produce an improvement by a factor of 10 in the radiated power for an electrically-small antenna when compared to conventional transmitter architecture. Results obtained over the past year, incorporating changes to the DDA circuit and measurement techniques reported previously, confirms that the radiated power improvement is close to a factor of 10 at similar to 1 MHz but changes with frequency. This letter discusses recent refinements made to the circuit design, measurement technique and results, and shows data demonstrating operation of a DDA transmitter across the AM broadcast band.

In order to capture the non-uniformity of line parameters caused by ambient temperature gradients, these models are characterized by multiple lumped segments which are non-uniform in length and parameter values.

The standard approach is to use the Global Positioning System (GPS), but this system performs poorly near tall buildings where line of sight to a sufficient number of satellites cannot be obtained. Most previous vision-based approaches for localization register ground imagery to a previously generated ground-level model of the environment. Generating such a model can be difficult and time consuming, and is impractical in some environments. Instead, we propose to perform localization by registering a single omnidirectional ground image to a 2D urban terrain model that is easily generated from aerial imagery. We introduce a novel image descriptor that encodes the position and orientation of a camera relative to buildings in the environment. The descriptor is efficiently generated from edges and vanishing points in an omnidirectional image and is registered to descriptors previously generated for the terrain model. Rather than constructing a local CAD-like model of the environment, which is difficult in cluttered environments, our descriptor measures, at equally spaced intervals over the 360 degrees field of view, the orientation of visible building facades projected onto the ground plane (i.e., the building footprints). We evaluate our approach on an urban data set with significant clutter and demonstrate an accuracy of about 1 m, which is an order of magnitude better than commercial GPS operating in open environments.

In particular, mobile platform localization and guidance in urban environments can be enabled with an accurate segmentation of the various building facades in a scene. Toward that end, we present a system for segmenting and labeling an input image that for each pixel, seeks to answer the question "Is this pixel part of a building facade, and if so, which one?" The proposed method determines a set of candidate planes by sampling and clustering points from the image with Random Sample Consensus (RANSAC), using local normal estimates derived from Principal Component Analysis (PCA) to inform the planar model. The corresponding disparity map and a discriminative classification provide prior information for a two-layer Markov Random Field model. This MRF problem is solved via Graph Cuts to obtain a labeling of building facade pixels at the mid-level, and a segmentation of those pixels into particular planes at the high-level. The results indicate a strong improvement in the accuracy of the binary building detection problem over the discriminative classifier alone, and the planar surface estimates provide a good approximation to the ground truth planes.

Jumping at small sizes requires the quick release of stored energy to accelerate the robot to its takeoff velocity. Two approaches to this energy release are considered. The first is similar to the method used by most larger jumping robots and insects; energy is stored mechanically and generates thrust against the ground upon release. A new microfabrication process incorporates polymer springs for the robot leg and the resulting 4mm x 4mm x 0.3mm jumping mechanism has been launched over 32 cm into the air by hand. The second approach utilizes stored chemical energy and generates thrust by expelling gas from a chemical reaction. This energetic material has been combined with sensing, control, and power on a 4mm x 7mm x 4mm polymer chassis, and jumps in response to light stimuli have reached 8 cm in height.

There is a need to design a system to facilitate the analysis of a nation state's ability to compromise the confidentiality, availability, and integrity of a deployed tactical network. Research demonstrated that, on these networks, compromises due to security protocols violated by humans are much more common than compromises due to technological vulnerabilities. Therefore, this analysis focuses on developing a simulation modeling approach to analyze the effectiveness of security protocols "within the fortress" and to track the damage done by various forms of cyber attacks that have successfully breached the network perimeter. Our network model uses agent-based simulation in order to model the flow of information at the packet level with dictated behavior specific to the agents modeled: individual network packets, computer systems, routers, servers, and files. The advantage to using an agent-based, rather than a discrete-event, simulation model in this situation is that agent-based models focus on the relationship between entities from the bottom-up, such as at the network packet level, rather than the entire system from the top-down. The developed simulation model allows us to simulate various network attacks, observe their interaction with network security protocols, assess the resulting damage in terms of the network's availability, and quantify the damage in terms of sensitive information lost.

The broadcast nature of wireless channels unavoidably exposes such applications to jamming attacks. However, existing methods to characterize and detect jamming attacks cannot be applied directly to time-critical networks, whose communication traffic model differs from conventional models. In this paper, we aim at modeling and detecting jamming attacks against time-critical traffic. We introduce a new metric, message invalidation ratio, to quantify the performance of time-critical applications. A key insight that leads to our modeling is that the behavior of a jammer who attempts to disrupt the delivery of a time-critical message can be exactly mapped to the behavior of a gambler who tends to win a gambling game. We show via the gambling-based modeling and real-time experiments that there in general exists a phase transition phenomenon for a time-critical application under jamming attacks: as the probability that a packet is jammed increases from 0 to 1, the message invalidation ratio first increases slightly (even negligibly), then increases dramatically to 1. Based on analytical and experimental results, we further design and implement the JADE (Jamming Attack Detection based on Estimation) system to achieve efficient and robust jamming detection for time-critical wireless networks.

Complex regional pain syndrome (CRPS) is a multi-faceted compilation of painful conditions characterized by disproportionate regional pain (spontaneous and/or evoked) that is disproportionate in time or degree to the anticipated course of any known trauma. Presenting features of CRPS fall into four broad categories: Sensory, motor, autonomic dysfunction, and trophic changes located in a region rather than a dermatome. Design. Case report. Setting. Military medical and research center. Patient. In this report we present the case of a CRPS patient in whom a continuous ketamine and dexmedetomidine infusion was administered for analgosedation. Multiple continuous peripheral nerve blocks were simultaneously implemented, with the goal of maximal nociceptive blockade. Results. We reported an improvement in pain control, with a 97% reduction in morphine equivalents administered at day 22 post-intervention. Conclusions. The combination of ketamine and dexmedetomidine for analgosedation, and peripheral nerve blockade with local anesthetic was an effective treatment for CRPS in our patient. Further study of this intervention is warranted to further establish its reproducibility and clinical utility.

The present study addresses this need through the development of the Employee Perceptions of Participatory Ergonomics Questionnaire (EPPEQ). The questionnaire is designed to assess five key components that are based on a review of the available literature: Employee Involvement. Knowledge Base, Managerial Support, Employee Support, and Strain related to ergonomic changes. In Phase 1, a sample of employees and ergonomists working at a manufacturing plant was used to develop and test an initial set of items. In Phase 2, data was collected from a nation-wide sample of employees representing a wide range of jobs and organizations to cross-validate the results from Phase 1. Phase 2 results indicate that the five EPPEQ subscales demonstrate sound convergent validity and are also correlated with traditional indicators of PE program success. Implications and uses of the EPPEQ are discussed. (C) 2010 Elsevier Ltd. All rights reserved. C1 [Matthews, Russell A.] Louisiana State Univ, Dept Psychol, Baton Rouge, LA 70803 USA.

Here we systematically describe plausible dislocation interactions at twin boundaries. Depending on the characteristics of the dislocations and the driving stress, possible dislocation reactions at twin boundaries include cross-slip into the twinning plane to cause twin growth or de-twinning, formation of a sessile stair-rod dislocation at the twin boundary, and transmission across the twin boundary. The energy barriers for these dislocation reactions are described and compared. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved. C1 [Zhu, Y.

This technique produces deep trenches with controlled width variation along the vertical direction. Using an alternating sequence of Bosch etches, a combined cryogenic etching and/or chemical etching process, allows the Bosch etched layers to maintain the width defined by the mask, while the cryogenic/chemical etched layer creates a lateral undercut that decreases the width beneath the surface. The result is a 3D lattice structure with a stack of vertical square grids. This paper reports the experimental procedures and results of fabrication of a 3D lattice structure that forms an array of hollow-core waveguides. We also compare several different etch recipes for the attempt to produce a uniform structure with smooth walls. These techniques will reduce overall fabrication cost, increase yield and are compatible with CMOS processing. Using this method, one can fabricate a variety of Si/SOI based 3D PhC structures including hollow-core, high contrast grating, waveguide arrays.

Multidimensional models of silicon carbide (SiC) sublimation growth systems of varying levels of complexity have been developed to aid in the design, manufacture, and optimization of these growth systems. Since it is well known that SiC defect density and growth rate are strongly influenced by temperature distribution, an accurate assessment of this temperature distribution is required. In this work we present a heat transfer model accounting for conduction, radiation, and radio frequency induction heating to investigate numerically the temperature distribution within an axisymmetric apparatus during sublimation growth of SiC bulk single crystals by vapor transport (modified Lely method). Here, the evolution of the magnetic potential vectors and temperature distribution is studied during the heating process and, where feasible, compared with existing numerical experiments found within the literature.

If any damage occurs, the ability to withstand single or multiple hits from various threats could be compromised. While these issues are most likely to occur due to impacts from high velocity projectiles during combat, they may also be the result of low velocity impacts from collisions, severe environmental conditions, or foreign object debris. In this study, transparent materials will be tested by comparing baseline conditions to experimentally controlled damage states. Destructive testing including air gun and sphere impact testing will be used to simulate low velocity impacts in the field. Characterization of the damaged state will include visual inspection, cross-polarization, x-ray, and ultrasound techniques. The combination of destructive testing and characterization of the resulting damage can help to establish a damage acceptance criterion for transparent materials used in protective systems.

Elastic and anisotropic elastic-plastic crystal models represent mechanical behavior of SiC and AlON and grains, respectively. Cohesive zone models represent intergranular fracture. Failure data that can be used to inform macroscopic continuum models of ceramic behavior are collected and analyzed. Studied are effects of grain morphology, specimen size, and applied stress state on behavior of polycrystalline aggregates loaded dynamically at applied strain rates on the order of 10(5)/s. Results for SiC demonstrate shear-induced dilatation, increasing shear strength with increasing confinement or pressure, increasing strength with decreasing specimen size (in terms of number of grains), and decreasing strength variability with decreasing size. Results for AlON demonstrate increased initiation of slip activity-particularly in the vicinity of constrained grain boundaries-with confinement. C1 [Clayton, J. D.; Kraft, R.

However, the ability of a numerical model to realistically predict the response of ceramic armor to ballistic impact depends mainly on the selection of appropriate material models and availability of appropriate data. An initial study of the ability of the existing material models to predict the observed damage induced by 93% tungsten heavy alloy (WHA) cylindrical projectiles striking confined cylinders of hot-pressed boron carbide targets (B4C) at velocities between 819 m/s to 1205 m/s was performed. It was determined that the damage patterns were highly dependent on the properties of the confined ceramic and the impacting cylinder, whose failure behavior was difficult to model, and the strength and failure material models used for the modeling. The current paper will detail the results of parametric studies conducted of various model parameters in an attempt to simulate the observed damage and will detail ongoing efforts to improve the numerical results in order to accurately simulate the ballistic response of confined hot-pressed boron carbide targets.

The purpose of this cross-sectional study was to assess HIV awareness, knowledge, and condom use among FSWs in three Afghan cities. FSWs residing in Jalalabad, Kabul, and Mazar-i-Sharif were recruited through outreach programs and completed an interviewer-administered questionnaire and rapid tests for hepatitis B surface antigen, HIV, syphilis, and hepatitis C virus. Logistic regression identified factors associated with HIV awareness, comprehensive HIV knowledge (knowledge that HIV cannot be detected by sight, that condoms prevent HIV, and rejection of local misconceptions about HIV transmission), and consistent condom use (use with every sex act) with clients in the last six months. Of 520 participants, 76.9% had no formal education and 37.7% lived outside Afghanistan in the last five years. Nearly half (44.2%) were aware of HIV but, of these, only 17.4% (N=40) had comprehensive HIV knowledge. There were significant differences by site; FSWs in Jalalabad were more likely to be aware of HIV but FSWs in Kabul were more likely to have correct HIV knowledge and use condoms consistently with clients. Consistent client condom use was reported by 11.5% (N=60) and was independently associated with having more clients per month (AOR=1.99, 95% CI: 1.04-3.81). In conclusion, comprehensive HIV knowledge and consistent condom use with clients are low among Afghan FSWs in these cities. Efforts to reach this population should focus on relaying accurate information and expanding condom use with clients.

CA IDCRP HIV Working Grp TI Long-term CD4+lymphocyte response following HAART initiation in a US Military prospective cohort SO AIDS RESEARCH AND THERAPY LA English DT Article AB Background: Among HIV-infected persons initiating highly active antiretroviral therapy (HAART), early CD4+ lymphocyte count increases are well described. However, whether CD4+ levels continue to increase or plateau after 4-6 years is controversial. Methods: To address this question and identify other determinants of CD4+ response, we analyzed data for 1,846 persons from a prospective HIV military cohort study who initiated HAART, who had post-HAART CD4+ measurements, and for whom HIV seroconversion (SC) date was estimated. Results: CD4+ count at HAART initiation was <= 200 cells/mm(3) for 23%, 201-349 for 31%, 350-499 for 27%, and >= 500 for 19%. The first 6 months post-HAART, the greatest CD4+ increases (93-151 cells) occurred, with lesser increases (22-36 cells/year) through the first four years. Although CD4+ changes for the entire cohort were relatively flat thereafter, HIV viral load (VL) suppressors showed continued increases of 12-16 cells/year. In multivariate analysis adjusting for baseline CD4+ and post-HAART time interval, CD4+ responses were poorer in those with: longer time from HIV SC to HAART start, lower pre-HAART CD4+ nadir, higher pre-HAART VL, and clinical AIDS before HAART (P < 0.05). Conclusions: Small but positive long-term increases in CD4+ count in virally suppressed patients were observed. CD4+ response to HAART is influenced by multiple factors including duration of preceding HIV infection, and optimized if treatment is started with virally suppressive therapy as early as possible.

CA IDCRP HIV Working Grp TI Virologic outcomes of HAART with concurrent use of cytochrome P450 enzyme-inducing antiepileptics: a retrospective case control study SO AIDS RESEARCH AND THERAPY LA English DT Article AB Background: To evaluate the efficacy of highly-active antiretroviral therapy (HAART) in individuals taking cytochrome P450 enzyme-inducing antiepileptics (EI-EADs), we evaluated the virologic response to HAART with or without concurrent antiepileptic use. Methods: Participants in the US Military HIV Natural History Study were included if taking HAART for >= 6 months with concurrent use of EI-AEDs phenytoin, carbamazepine, or phenobarbital for >= 28 days. Virologic outcomes were compared to HAART-treated participants taking AEDs that are not CYP450 enzyme-inducing (NEI-AED group) as well as to a matched group of individuals not taking AEDs (non-AED group). For participants with multiple HAART regimens with AED overlap, the first 3 overlaps were studied. Results: EI-AED participants (n = 19) had greater virologic failure (62.5%) compared to NEI-AED participants (n = 85; 26.7%) for the first HAART/AED overlap period (OR 4.58 [1.47-14.25]; P = 0.009). Analysis of multiple overlap periods yielded consistent results (OR 4.29 [1.51-12.21]; P = 0.006). Virologic failure was also greater in the EI-AED versus NEI-AED group with multiple HAART/AED overlaps when adjusted for both year of and viral load at HAART initiation (OR 4.19 [1.54-11.44]; P = 0.005). Compared to the non-AED group (n = 190), EI-AED participants had greater virologic failure (62.5% vs. 42.5%; P = 0.134), however this result was only significant when adjusted for viral load at HAART initiation (OR 4.30 [1.02-18.07]; P = 0.046). Conclusions: Consistent with data from pharmacokinetic studies demonstrating that EI-AED use may result in subtherapeutic levels of HAART, EI-AED use is associated with greater risk of virologic failure compared to NEI-AEDs when co-administered with HAART. Concurrent use of EI-AEDs and HAART should be avoided when possible.

TI Postdischarge secobarbital after ED migraine treatment decreases pain and improves resolution SO AMERICAN JOURNAL OF EMERGENCY MEDICINE LA English DT Article; Proceedings Paper CT Research Forum of the American-College-of-Emergency-Physicians CY SEP 27-28, 2005 CL Washington, DC SP Amer Coll Emergency Phys ID EMERGENCY-DEPARTMENT; HEADACHE; SUMATRIPTAN; SLEEP AB Objective: The objective of the study was to determine whether the addition of postdischarge oral secobarbital to standard emergency department (ED) migraine headache therapy improves pain relief and headache resolution compared with placebo. Setting: The setting is an urban ED with 70 000 yearly visits. Methods: This is an Institutional Review Board-approved, randomized, nonconsecutive, double-blinded, concealed, and placebo-controlled clinical trial. Patients with a clinical diagnosis of migraine underwent standard ED treatment and were discharged with 2 tablets of either secobarbital 100 mg or placebo. At home arrival, subjects recorded headache pain on a visual analog scale (VAS), took 1 tablet, and went to bed, taking the second tablet after 1 hour if not asleep. Upon awakening, subjects completed a second VAS and survey. Statistical analysis: The VAS data were analyzed using 2-tailed t test with unequal variance. Headache resolution data were analyzed using Fisher exact test. Results: Fifty subjects were enrolled. Complete data and follow-up were available for 30 subjects (60%). Fourteen subjects received placebo; 16 received secobarbital. Secobarbital subjects reported an average headache pain decrease of 25 mm (-13 to -38) compared with an average increase of 3 mm (-13 to 19) in the placebo group (P = .01). Ninety-four percent of the secobarbital group vs 50% of the placebo group had complete or partial headache resolution (P < .02). All subjects in the secobarbital group reported some relief. Conclusions: Addition of postdischarge oral secobarbital to a standard ED migraine treatment regimen decreased headache pain at 24 hours after discharge and improved the rate of headache resolution compared with placebo.

TI The Timing of Hepatitis B Virus (HBV) Immunization Relative to Human Immunodeficiency Virus (HIV) Diagnosis and the Risk of HBV Infection Following HIV Diagnosis SO AMERICAN JOURNAL OF EPIDEMIOLOGY LA English DT Article DE hepatitis B vaccines; hepatitis B virus; HIV; immunization; vaccination ID US MILITARY COHORT; UNITED-STATES; PROPENSITY SCORE; HOMOSEXUAL-MEN; VACCINATION; RECOMMENDATIONS; INDIVIDUALS; ADULTS; EPIDEMIOLOGY; MORTALITY AB To assess associations between the timing of hepatitis B virus (HBV) immunization relative to human immunodeficiency virus (HIV) diagnosis and vaccine effectiveness, US Military HIV Natural History Study cohort participants without HBV infection at the time of HIV diagnosis were grouped by vaccination status, retrospectively followed from HIV diagnosis for incident HBV infection, and compared using Cox proportional hazards models. A positive vaccine response was defined as hepatitis B surface antibody level >= 10 IU/L. Of 1,877 participants enrolled between 1989 and 2008, 441 (23%) were vaccinated prior to HIV diagnosis. Eighty percent of those who received vaccine doses only before HIV diagnosis had a positive vaccine response, compared with 66% of those who received doses both before and after HIV and 41% of those who received doses only after HIV (P < 0.01 for both compared with persons vaccinated before HIV only). Compared with the unvaccinated, persons vaccinated only before HIV had reduced risk of HBV infection after HIV diagnosis (hazard ratio = 0.38, 95% confidence interval: 0.20, 0.75). No reduction in HBV infection risk was observed for other vaccination groups. These data suggest that completion of the vaccine series prior to HIV infection may be the optimal strategy for preventing this significant comorbid infection in HIV-infected persons.

Using the US Renal Data Base System, we analyzed the safety profile of these agents in the elderly. Methods: In a cohort of patients transplanted from January 2000 to July 2009 and followed through 2009, we assessed the effect of induction on allograft loss and death among elderly recipients. Recipients were censored at dates of allograft loss, death or the end of study. Independent associations between induction agents and allograft loss or death were examined using multivariate analysis with forward stepwise Cox regression. Results: Among 130,402 patients with first transplants, 14,907 were age 65 years or older. 4,466 (30%), 3,049 (20.5%), 1,501 (10.1%), and 999 (6.7%) were induced with thymoglobulin, basiliximab, daclizumab, and alemtuzumab, respectively. After adjusting for baseline differences, induction with alemtuzumab was associated with an increased risk of graft loss and death, with an adjusted hazard ratio (AHR) of 1.26 (95% CI 1.08-1.48). Risk was also present at other age cutoffs [age >60 (AHR 1.16; 95% CI 1.03-1.31; p = 0.014), age >70 (AHR 1.43; 95% CI 1.13-1.81; p = 0.003) and age >75 (AHR 1.68; 95% CI 1.07-2.63; p = 0.024)]. Conclusions: In the elderly, alemtuzumab is associated with an escalating risk of death and graft loss in recipients of kidney transplantations. Copyright (C) 2011 S.

In response, the Army's Comprehensive Soldier Fitness (CSF) program is a preventive program that seeks to enhance psychological resilience among all members of the Army community, which includes soldiers, family members, and Department of the Army civilians. CSF is not a medical treatment program. Rather, CSF helps those community members who are psychologically healthy face life's adversities-including combat and prolonged separation from loved ones-by providing evidence-based training.

Based on the principles of positive psychology, CSF is a historically unique approach to behavioral health in a large (1.1 million members) organization. There are four program elements: (a) the assessment of emotional, social, family, and spiritual fitness; (b) individualized learning modules to improve fitness in these domains; (c) formal resilience training; and (d) training of Army master resilience trainers (MRTs) to instill better thinking skills and resilience in their subordinates. In contrast to traditional approaches, CSF is proactive; rather than waiting to see who has a negative outcome following stress, it provides ways of improving resilience for all members of the Army. CSF aims to move the full spectrum of responses to trauma and adversity-ranging from stress-related disorders to ordinary resilience-toward personal growth. This program may provide a model for implementing similar interventions in other very large institutions. C1 [Matthews, Michael D.] US Mil Acad, Dept Behav Sci & Leadership, West Point, NY 10096 USA.

The U.S. Army Comprehensive Soldier Fitness (CSF) program aims to measure the psychosocial strengths and assets of soldiers as well as their problems, to identify those in need of basic training in a given domain as well as those who would benefit from advanced training, and then to provide that training. The goals of the CSF program include the promotion of well-being as well as the prevention of problems. Assessment is the linchpin of the CSF program, and the Global Assessment Tool (GAT) is a self-report survey that measures psychosocial fitness in emotional social, family, and spiritual domains. We review the history of psychological assessment in the military and the lessons taught by this history. Then we describe the process by which the GAT was developed and evaluated. We conclude with a discussion of pending next steps in the development and use of the GAT. C1 [Peterson, Christopher; Park, Nansook] Univ Michigan, Dept Psychol, Ann Arbor, MI 48109 USA.

TI Building Spiritual Fitness in the Army An Innovative Approach to a Vital Aspect of Human Development SO AMERICAN PSYCHOLOGIST LA English DT Article DE spirituality; resilience; prevention; values; spiritual struggles ID SELF-REGULATION; RELIGION AB This article describes the development of the spiritual fitness component of the Army's Comprehensive Soldier Fitness (CSF) program. Spirituality is defined in the human sense as the journey people take to discover and realize their essential selves and higher order aspirations. Several theoretically and empirically based reasons are articulated for why spirituality is a necessary component of the CSF program: Human spirituality is a significant motivating force, spirituality is a vital resource for human development, and spirituality is a source of struggle that can lead to growth or decline. A conceptual model developed by Sweeney, Hannah, and Snider (2007) is used to identify several psychological structures and processes that facilitate the development of the human spirit. From this model, an educational, computer-based program has been developed to promote spiritual resilience. This program consists of three tiers: (a) building awareness of the self and the human spirit, (b) building awareness of resources to cultivate the human spirit, and (c) building awareness of the human spirit of others. Further research will be needed to evaluate the effectiveness of this innovative and potentially important program.

The empirical assessment includes four major components. First, the CSF scientific staff is currently conducting a longitudinal study to determine if the Master Resilience Training program and the Comprehensive Resilience Modules lead to lasting resilience development in soldiers. Second, the CSF program has partnered with other researchers to conduct a series of longitudinal studies examining the link between physiological, neurobiological, and psychological resilience factors. Third, the CSF program is also incorporating institutional-level data to determine if its material influences health, behavioral, and career outcomes. Fourth, group randomized trials are being conducted to ensure that resilience training incorporated under the CSF program is effective with soldiers. A specific rationale and methodologies are discussed. C1 [Lester, Paul B.; McBride, Sharon] DAMO CSF, Dept Army, Arlington, VA 22203 USA.

Electrode fabrication, however, has proven to be a major obstacle in the field. Here, an alternative method to create integrated, low cost, robust, patternable carbon paste electrodes (CPEs) for microfluidic devices is presented. The new CPEs are composed of graphite powder and a binder consisting of a mixture of poly(dimethylsiloxane) (PDMS) and mineral oil. The electrodes are made by filling channels molded in previously cross-linked PDMS using a method analogous to screen printing. The optimal binder composition was investigated to obtain electrodes that were physically robust and performed well electrochemically. After studying the basic electrochemistry, the PDMS-oil CPEs were modified with multi-walled carbon nanotubes (MWCNT) and cobalt phthalocyanine (CoPC) for the detection of catecholamines and thiols, respectively, to demonstrate the ease of electrode chemical modification. Significant improvement of analyte signal detection was observed from both types of modified CPEs. A nearly 2-fold improvement in the electrochemical signal for 100 mu M dithiothreitol (DTT) was observed when using a CoPC modified electrode (4.0 +/- 0.2 nA (n = 3) versus 2.5 +/- 0.2 nA (n = 3)). The improvement in signal was even more pronounced when looking at catecholamines, namely dopamine, using MWCNT modified CPEs. In this case, an order of magnitude improvement in limit of detection was observed for dopamine when using the MWCNT modified CPEs (50 nM versus 500 nM). CoPC modified CPEs were successfully used to detect thiols in red blood cell lysate while MWCNT modified CPEs were used to monitor temporal changes in catecholamine release from PC12 cells following stimulation with potassium.

TI Label-free imaging of cell attachment with photonic crystal enhanced microscopy SO ANALYST LA English DT Article ID DIFFERENTIATION AB We introduce photonic crystal enhanced microscopy (PCEM) as a label-free biosensor imaging technique capable of measuring cell surface attachment and attachment modulation. The approach uses a photonic crystal optical resonator surface incorporated into conventional microplate wells and a microscope-based detection instrument that measures shifts in the resonant coupling conditions caused by localized changes in dielectric permittivity at the cell-sensor interface. Four model systems are demonstrated for studying cancer cells, primary cardiac muscle cells, and stem cells. First, HepG2/C3 hepatic carcinoma cells were cultured and observed via PCEM in order to characterize cell adhesion in the context of growth and locomotion. Second, Panc-1 pancreatic cancer cells were used to verify that cell attachment density decreases in response to staurosporine, a drug that induces apoptosis. Third, we used PCEM to confirm the influence of integrin-mediated signaling on primary neonatal cardiomyocyte growth and development. Rounded cardiomyocytes consistently showed decreased cell attachment density as recorded via PCEM, while spreading cells exhibited greater attachment strength as well as increased contractility. Finally, PCEM was used to monitor the morphological changes and extracellular matrix remodeling of porcine adipose-derived stem cells subjected to a forced differentiation protocol. Each of these experiments yielded information regarding cell attachment density without the use of potentially cytotoxic labels, enabling study of the same cells for up to several days.

A shift from multi-year to seasonal ice in large portions of the Arctic presents a challenge for the existing Lagrangian array of autonomous ice mass-balance buoys, which were designed with a perennial ice cover in mind. This work identifies the anticipated challenges of operation in seasonal ice and presents a new autonomous buoy designed to monitor ice mass balance in the seasonal ice zone. The new design presented incorporates features which allow the buoy to operate in thin ice and open water, and reduce its vulnerability to ice dynamics and wildlife damage, while enhancing ease of deployment. A test deployment undertaken from April to June 2009 is discussed and results are presented with analysis to illustrate both the features and limitations of the buoy's abilities.

TI Modelling the reorientation of sea-ice faults as the wind changes direction SO ANNALS OF GLACIOLOGY LA English DT Article ID TENSILE-STRENGTH; LEAD ICE; IN-SITU; FRACTURE; FAILURE; SCALE; COMPRESSION; SATELLITE; RHEOLOGY; CRACKS AB A discrete-element model of sea ice is used to study how a 900 change in wind direction alters the pattern of faults generated through mechanical failure of the ice. The sea-ice domain is 400 km in size and consists of polygonal floes obtained through a Voronoi tessellation. Initially the floes are frozen together through viscous-elastic joints that can break under sufficient compressive, tensile and shear deformation. A constant wind-stress gradient is applied until the initially frozen ice pack is broken into roughly diamond-shaped aggregates, with crack angles determined by wing-crack formation. Then partial refreezing of the cracks delineating the aggregates is modelled through reduction of their length by a particular fraction, the ice pack deformation is neglected and the wind stress is rotated by 90 degrees. New cracks form, delineating aggregates with a different orientation. Our results show the new crack orientation depends on the refrozen fraction of the initial faults: as this fraction increases, the new cracks gradually rotate to the new wind direction, reaching 90 degrees for fully refrozen faults. Such reorientation is determined by a competition between new cracks forming at a preferential angle determined by the wing-crack theory and at old cracks oriented at a less favourable angle but having higher stresses due to shorter contacts across the joints.

Repeated EM surveys along an originally 2160 m long profile including level and deformed ice showed that between June and September modal and mean thicknesses decreased by 0.6 and 0.86 m respectively. The modal thickness decrease is in good agreement with the thinning of 0.6 m observed by the ice mass-balance buoy at one location on unponded ice during the same period, although the local observations do not capture the different melt rates on level and rough ice. The paper discusses methodological and operational challenges in sustaining both measurement; over periods of several months, and concludes that more work needs to be done to better understand their representativeness.

TI Solar partitioning in a changing Arctic sea-ice cover SO ANNALS OF GLACIOLOGY LA English DT Article ID ALBEDO; OCEAN; EVOLUTION; SUMMER AB The summer extent of the Arctic sea-ice cover has decreased in recent decades and there have been alterations in the timing and duration of the summer melt season. These changes in ice conditions have affected the partitioning of solar radiation in the Arctic atmosphere-ice-ocean system. The impact of sea-ice changes on solar partitioning is examined on a pan-Arctic scale using a 25 km x 25 km Equal-Area Scalable Earth Grid for the years 1979-2007. Daily values of incident solar irradiance are obtained from NCEP reanalysis products adjusted by ERA-40, and ice concentrations are determined from passive microwave satellite data. The albedo of the ice is parameterized by a five-stage process that includes dry snow, melting snow, melt pond formation, melt pond evolution, and freeze-up. The timing of these stages is governed by the onset dates of summer melt and fall freeze-up, which are determined from satellite observations. Trends of solar heat input to the ice were mixed, with increases due to longer melt seasons and decreases due to reduced ice concentration. Results indicate a general trend of increasing solar heat input to the Arctic ice-ocean system due to declines in albedo induced by decreases in ice concentration and longer melt seasons. The evolution of sea-ice albedo, and hence the total solar heating of the ice-ocean system, is more sensitive to the date of melt onset than the date of fall freeze-up. The largest increases in total annual solar heat input from 1979 to 2007, averaging as much as 4% a(-1), occurred in the Chukchi Sea region. The contribution of solar heat to the ocean is increasing faster than the contribution to the ice due to the loss of sea ice. C1 [Perovich, D. K.; Jones, K.

Data from autonomous ice mass-balance buoys can enhance our understanding of this decline. These buoys monitor changes in snow deposition and ablation, ice growth, and ice surface and bottom melt. Result; from the summer of 2008 showed considerable large-scale spatial variability in the amount of surface and bottom melt. Small amounts of melting were observed north of Greenland, while melting in the southern Beaufort Sea was quite large. Comparison of net solar heat input to the ice and heat required for surface ablation showed only modest correlation. However, there was a strong correlation between solar heat input to the ocean and bottom melting. As the ice concentration in the Beaufort Sea region decreased, there was an increase in solar heat to the ocean and an increase in bottom melting.

Roberts, Andrew Geiger, Cathleen A. Richter-Menge, Jacqueline TI Spatial and temporal characterization of sea-ice deformation SO ANNALS OF GLACIOLOGY LA English DT Article ID FRACTURE; HIERARCHY AB In late March 2007 an array of GPS ice drifters was deployed in the Beaufort Sea as part of the Sea Ice Experiment: Dynamic Nature of the Arctic (SEDNA). The drifters were deployed in an array designed to resolve four, nested spatial scales of sea-ice deformation, from 10 to 140 km, with the arrays maintaining appropriate shape for strain-rate calculation until mid-June. In this paper, we test whether sea-ice deformation displays fractal properties in the vicinity of SEDNA. We identify that deformation time series have different spectral properties depending on the spatial scale. At the scales around 100 km, deformation is a red-noise process, indicating the importance of the ice-pack surface forcing in determining the deformation rate of sea ice at this scale. At smaller scales, the deformation becomes an increasingly whiter process (it has pink noise properties), which suggests an increasing role of dissipative processes at smaller scales. At spatial scales of 10-100 km, and sub-daily scales, there is no deformation coherence across scales; coherence only becomes apparent at longer scales greater than 100 km. The lack of coherence at small scales aids in understanding previous observations where correlation between 10 km regions adjacent to each other varied widely, with correlation coefficients between 0.3 and 1. This suggests it is not appropriate to think of sea ice as having a decorrelation length scale for deformation. We find that lead scale observations of deformation are required when estimating ice growth in leads and ridging time series. For the two SEDNA arrays, we find coherence between 140 and 20 km scale deformation up to periods of 16 days. This suggests sea-ice deformation displays coherent deformation between 100 km scale and the scale of the Beaufort Sea (of order 1000 km), over synoptic time periods (daily to weekly timescales). Organization of leads at synoptic and larger scales is an emergent feature of the deformation field that is caused by the smooth variation of surface forcing (wind) on the ice pack.

Similarly, the number of resected/evaluated nodes impacts staging accuracy. This ratio of metastatic to examined nodes or lymph node ratio (LNR) may have independent prognostic value in colon carcinoma. Purpose: To evaluate the impact of LNR on overall survival in colon cancer patients with fewer than 12 or 12 examined nodes or more. Methods: Patients (n = 36,712) with node-positive nonmetastatic colon cancer diagnosed between 1992 and 2004 were identified from the Surveillance, Epidemiology, and End Results database and stratified according to LNR and number of nodes examined. Survival was estimated by Kaplan-Meier method, and differences analyzed by log-rank test. A Cox proportional hazards model was used for multivariate analysis. Results: Patients with fewer than 12 nodes were older and male and had lower primary tumor stage, grade, and N stage (P < 0.01). Survival appeared greater with 12 total nodes examined or more (median 53 vs. 66 months, P < 0.001). Within each LNR stratum, survival with 12 nodes or more was improved for those with less than 10% of nodes positive for cancer, but was worse with higher LNRs (P < 0.01). Lymph node ratio was significantly associated with survival independent of total nodes (HR 1.24-5.12, P < 0.001). Other significant factors included age, race, tumor grade, stage, location, and N stage. Conclusion: Metastatic LNR independently estimates survival in Stage III colon cancer, irrespective of number of nodes examined. However, statistically significant differences in each LNR stratum between those with resection of fewer than 12 or 12 nodes or more would indicate that a 12-node minimum may still be necessary for accurate staging.

TI Endovascular Repair of an Abdominal Aortic Aneurysm in a Patient With Stenosis of Bilateral Common Iliac Artery Stents SO ANNALS OF VASCULAR SURGERY LA English DT Article; Proceedings Paper CT 20th Annual Winter Meeting of the Peripheral-Vascular-Surgery-Society CY JAN 29-31, 2010 CL Vail, CO SP Peripheral Vasc Surg Soc ID FEMOROFEMORAL CROSSOVER; DURABILITY AB Background: The explosion in endovascular interventions for peripheral vascular disease has resulted in procedures being used by a multitude of specialties. Nonvascular surgeons performing these interventions can create scenarios that may make future vascular interventions difficult. In this article, we present a case report illustrating this point. Methods: A 68-year-old man with severe chronic obstructive pulmonary disease, coronary artery disease with prior myocardial infarction, and multiple abdominal operations presented with an abdominal aortic aneurysm. In our opinion, this patient was at a prohibitive operative risk for open repair. Review of his imaging results revealed a 6.7-cm infrarenal aneurysm with bilateral common iliac artery (CIA) stents (right: 8 mm; left: 6 mm) and 6-mm self-expanding stents extending from the right external iliac artery through the common femoral artery. A Cook Zenith Renu (30 x 108 mm) graft (Cook Medical Inc., Bloomington, IN) was advanced after serial dilation and balloon angioplasty of the stenotic right CIA stent. Left brachial access was used for arteriographic imaging. The left common femoral artery was accessed and the left CIA was coil-embolized to prevent backbleeding. A femoro-femoral artery crossover bypass was then performed after segmental resection of the right common femoral artery stent. Results: The patient tolerated the procedure well and was discharged home on postoperative day 3. Subsequent postoperative computed tomography arteriogram after 1 month showed palpable pulses and no evidence of endoleak with flow in the femoro-femoral graft on clinical exam. Conclusions: This case demonstrates an endovascular intervention which limited the potential options available for aneurysm repair. Similar problems may become increasingly common as more providers offer endovascular interventions, thus emphasizing the importance of a collaborative approach to the patient with complex aorto-iliac occlusive disease and abdominal aortic aneurysm. It is the duty of the vascular surgeon to offer his vital expertise and leadership in the care of these patients.

Tests with currently used cell-based assays provide an indication of a compound's potential therapeutic benefits to the target tissue, but not to the whole body. Data obtained with animal models often cannot be extrapolated to humans. Multicompartment microfluidic-based devices, particularly those that are physical representations of physiologically based pharmacokinetic (PBPK) models, may contribute to improving the drug development process. These scaled-down devices, termed micro cell culture analogs (mu CCAs) or body-on-a-chip devices, can simulate multitissue interactions under near-physiological fluid flow conditions and with realistic tissue-to-tissue size ratios. Because the device can be used with both animal and human cells, it can facilitate cross-species extrapolation. Used in conjunction with PBPK models, the devices permit an estimation of effective concentrations that can be used for studies with animal models or predict the human response. The devices also provide a means for relatively high-throughput screening of drug combinations and, when utilized with a patient's tissue sample, an opportunity for individualized medicine. Here we review efforts made toward the development of microfabricated cell culture systems and give examples that demonstrate their potential use in drug development, such as identifying synergistic drug interactions as well as simulating multiorgan metabolic interactions. In addition to their use in drug development, the devices also can be used to estimate the toxicity of chemicals as occupational hazards and environmental contaminants. C1 [Esch, M. B.; Shuler, M.

Basis of this framework is the characterization of each hurricane scenario through five model parameters: the location and angle of landfall, the central pressure, the forward speed, and the radius of maximum winds. Description of the uncertainty in these parameters, through appropriate probability models, leads then to quantification of hurricane risk as a probabilistic integral. One of the greater advances in this field has been the development and adoption of high fidelity numerical simulation models for reliable and accurate prediction of hurricane impact for a specific event. This approach significantly increases, though, the computational cost for estimating risk since this estimation requires evaluation of the surge response for a large number of hurricane scenarios, representing the entire space for possible hazard uncertainties. For efficiently performing this task an approach based on response surface methodologies is discussed in this paper: using information from a small amount of pre-computed high-fidelity numerical simulation, response surfaces are built as a surrogate model for efficiently predicting surge responses and these surfaces are then used for efficient risk assessment. An illustrative example is presented that considers applications of these tools for hurricane risk estimation for the Oahu Island in Hawaii. C1 [Taflanidis, A. A.; Kennedy, A. B.; Westerink, J.

Dams are no exception to this dilemma. Spillway gate systems are among the most critical for maintaining the safety of a dam and require assessments of both equipment and operational failure modes. Safety can be ensured by conducting regular inspections and tests of the facilities, by assessing the performance level of the various components and implementing a regular maintenance program. These tasks can be optimized by performing risk analyses and by identifying the components that are most critical to the operation of the facility. The first part of this paper reviews these methodologies and their advantages and limitations. Although extensive work has been done in this area, little attention has been given to the dormant condition of the spillway gates. The second part of this paper addresses the dormancy issue of spillway gates by incorporating the effect of the dormancy period in the currently existing reliability and risk assessment approaches. Finally, the paper concludes by presenting a brief case study on a vertical gate to demonstrate the applicability of this approach.

Nearly twice as many examinees failed the NV-MSVT than the TOMM. Profile analyses of the NV-MSVT demonstrated patterns suggestive of inconsistent effort in those who failed the NV-MSVT but passed the TOMM. A classification analysis employing the Word Memory Test and Medical Symptom Validity Test as external criteria for poor effort showed that the NV-MSVT is substantially more sensitive to poor effort than the TOMM and maintains an acceptable false-positive rate. Overall, results closely matched those of the Green (in press) study and extend the evidence that the NV-MSVT possesses better sensitivity to poor effort than the TOMM.

Ph1prol (PH0974) has previously been isolated and characterized from Pyrococcus horikoshii and was shown to have higher catalytic activity over a broader pH range, higher affinity for metal, and increased thermostability compared to P. furiosus prolidase, Pfprol (PF1343). To obtain a better enzyme for OP nerve agent decontamination and to investigate the structural factors that may influence protein thermostability and thermoactivity, randomly mutated Ph1prol enzymes were prepared. Four Ph1prol mutants (A195T/G306S-, Y301C/K342N-, E127G/E252D-, and E36V-Ph1prol) were isolated which had greater thermostability and improved activity over a broader range of temperatures against Xaa-Pro dipeptides and OP nerve agents compared to wild type Pyrococcus prolidases.

TI Correlational Sperm Motility Analysis: Wild Rodent Progressive Sperm Motility as a Potentially Improved Reproduction-Assessment Parameter in Mammals SO ARCHIVES OF ENVIRONMENTAL CONTAMINATION AND TOXICOLOGY LA English DT Article ID MICE; FERTILIZATION AB Progressive sperm motility, describing the directed or linear movement of sperm, is infrequently reported in reproductive studies conducted with rodents. This is a curious circumstance given that progressive motility can be easily reported with current computer-assisted sperm-analysis equipment, and because progressively motile sperm seemingly display a greater likelihood of fertilizing ova than do sperm that move in a random or undefined pattern. This study presents a comparison of the routinely reported total motility (i.e., the percentage of moving sperm cells in a sample) and the progressive motility of sperm from rodents captured at soil-contaminated sites and at habitat-matched noncontaminated reference locations. Progressive motility's trending with total motility at all areas, in terms of direction of shift, magnitude of change, and degree of correlation, was extremely high. Based on these results and in the interest of assisting ecological health assessments at contaminated sites, it would seem prudent to conduct the empirical research to determine progressive sperm motility's threshold-for-effect, which may be lower than that for total motility.

We determined the density and size distribution of Burkholderia pseudomallei cells in comparison with other Burkholderia species, including B. mallei and B. thailandensis, all prepared and analyzed under similar conditions. The observed size distribution and densities of several bacterial strains indicates that aerosolized particles consisting of one or of a few B. pseudomallei cells should be efficiently retained in the lungs, highlighting the risk of transmission of melioidosis by the respiratory route when the pathogen is present in fluids from infected patients or aerosolized from the environment.

Administrative/office buildings and production and maintenance facilities pose specific challenges to those seeking improved energy management and building energy performance. Questions of energy consumption in these buildings are generally seen as secondary to the improvement of comfort and/or functionality. This is most pronounced within the existing building stock. Decisions to retrofit a building are often made because of dissatisfaction concerning the comfort level or as a consequence of changes in building use or in processes performed in the building. The primary goal of the retrofit is to improve these conditions. Good technologies to meet this end are currently available. The objectives of the International Energy Agency Energy Conservation in Buildings and Community Systems (ECBCS) Programme Annex 46 (IEA 2011a) is intended to provide tools and guidelines to identify energy conservation opportunities in buildings and to improve the indoor environment of these buildings in energy-efficient retrofitting projects. Among the tools developed by this project is the Energy and Process Assessment Protocol, which provides an energy assessment methodology and procedure suitable for different types of sites, including a variety of different nonindustrial buildings with energy requirements dominated by climate, and industrial buildings with high energy loads dominated by internal processes and high ventilation requirements per floor space. This paper presents the energy assessment methodology for a single building or a large building stock, along with examples of typical energy wastes and inefficiencies in different types of buildings and typical processes.

In this paper, we discuss a Monte Carlo channel model for NLOS UV communications that accounts for the possibility that a transmitted photon experiences multiple scattering events before being received. By simulating the propagation of many photons based on probabilistic rules derived from physics considerations, a computationally efficient algorithm is obtained that allows for the study of the contribution of various orders of scattering to the received signal and to the system impulse response function. We then demonstrate the use of this channel model in the exploration of several system configurations. In particular, we examine the effect of the transmitter beam shape and receiver sensitivity function on the faithfulness of a well-known linear model of path loss versus distance for short-range NLOS UV systems, and we explore geometry design for interference reduction in a full-duplex link. The use of the model to study such diverse system implementations demonstrates its general applicability.

The use of receiver operator characteristic curves (ROCs) is a defacto standard, but they do not communicate several key performance measures, including (i) intrinsic separation between classes in the input space, (ii) the efficacy of the mapping induced by the algorithm, (iii) the complexity of the algorithmic mapping, and (iv) a measure of the generalization of the proposed solution. Previous work by Sims et. al.(2,5) has addressed the distortion of the evaluation sets to indicate an algorithm's capability (or lack thereof) for generalization and handling of unspecified cases.

This paper intends to address why delivery of an energy efficient building is not just the result of applying one or more isolated technologies. Rather, it can best be obtained using an integrated whole building process throughout the entire project development process, which leads building designers to generate a large amount of data during energy simulations. The authors observed that even a simple energy modeling run generated pages of data with many different variables. The volumes of energy modeling data clearly overwhelm traditional data analysis methods such as spreadsheets and ad-hoc queries with so many factors to be considered. An integrated or whole building design process involves studies of the energy-related impacts and interactions of all building components, including the building location, envelope (walls, windows, doors, and roof), heating, ventilation and air conditioning (HVAC) system, lighting, controls, and equipment, which shows why it is so difficult to find the correlation between different systems. The objective of this research is to develop an energy efficient building design process using data mining technology which can help project teams discover important patterns to improve the building design. This paper utilizes the data mining technology to extract interrelationships and patterns of interest from a large dataset Case study revealed that data mining based energy modeling help project teams discover useful patterns to improve the energy efficiency of building design during the design phase. The method developed during this research could be used to guide designers and engineers through the process of completing an early design energy analysis based on energy simulation models.

Automated Neuropsychological Assessment Metrics: repeated assessment with two military samples. Aviat Space Environ Med 2011; 82:34-9. Introduction: U.S. military troops deploying to war zones are currently administered the Automated Neuropsychological Assessment Metrics (ANAM4) Traumatic Brain Injury (TBI) Battery to establish individual neurocognitive performance baselines. In part, the utility of the ANAM4 TBI Battery baseline measurement depends on test-retest reliability of this instrument. The purpose of this report was to evaluate performance following multiple administrations of the ANAM4 TBI Battery: does performance in a repeated measures paradigm constitute a stable, interpretable indication of baseline neurocognitive ability? Methods: The data presented here are from the ANAM4 TBI Battery administered four times to a group of U.S. Marines in Study 1 and eight times to a group of New Zealand Defence Force personnel in Study 2. Results: The results show practice effect in five of six performance sub-tests in both Study 1 and Study 2. Discussion: Results are consistent with expectations that multiple test sessions are required to reach stable performance on some computerized tasks. These results have implications for taking ANAM4 TBI Battery practice effects into account in test administration and in data interpretation.

This paper summarizes the incremental steps taken to evaluate a specific type of cartridge case failure, with a focus on the computational modeling used to capture the physics behind the failure. The results of modeling and testing are coordinated to conclude the evaluation. Personal observations of a system malfunction often lead to false accusations about the cause, until more detailed understanding is achieved. Generating higher chamber pressures, as a result of inappropriately applied lubricaiton, is one of those false assumptions. Data generated using Finite Element Analysis, when combined with data from testing, provided insight and understanding of the forces surrounding ignition and obturation of the typical ammunition cartridge. This effort is a fine example of a collaborating test data with M&S, using each to assist the other throughout the course of the investigation.

The use of these dense HEs creates significant design, performance, and safety issues. Structural integrity requires that the warhead sidewall be able to withstand gun-launch loads that include the loading from the dense HE fill. A competing requirement is that the performance of the low collateral warhead is strongly influenced by the burst strength of the warhead sidewall. One approach to reduce the required warhead sidewall burst strength is to design a reinforcement system that effectively redistributes that loading. For demonstration purposes, a hexagonal honeycomb structure is used to reinforce the dense HE. The finite element analyses show that the honeycomb structure is effective in reducing the sidewall load and greatly reduces the warhead's required burst strength to survive gun-launch. This paper details these analyses. C1 USA, Weap & Mat Directorate, Res Lab, Aberdeen Proving Ground, MD 21005 USA.

The impulse data were collected at a small-scale test facility designed and operated by the U.S. Army Research Laboratory (ARL) Weapons and Materials Research Directorate (WMRD). The facility uses stereo-digital image correlation to track the motion of a speckled pattern painted on the top floor plate of the target. This capability allow for the measurement of the vibration motion of the top floor plate from which the global motion of the target can also be derived. Experiments were performed using three v-shaped targets with angles of 10, 20 and 30 degrees. Centerline shots were performed on each structure using two cylindrical C-4 charge sizes, 600g and 800g, each with a 1:3 height-to-diameter ratio. Off-center shots were performed for the 20 degree target with C-4 charge sizes 800g and 1000g. Finite element modeling and statistical analysis of the experimental data was performed by the Survivability Lethality Analysis Directorate (SLAD) of ARL.

Glass liners are used in a large variety of shaped charge applications. Explosively packed bottles have long been used as improvised shaped charges. Standard demolition shaped charges use glass liners for geologic materials penetrations. Shaped charge jet radiography reveals the extreme particulate nature of these jets. A series of progressively higher density glasses have also been explored. Jet radiography results from these tests show distinct regions of resulting jet behavior with extreme particulate, ductile or radially dispersed behaviors. The resulting jet behavior appears to be both material and design dependent. Extremely long standoff x-rays of coherent glass jets revealed a late time jet instability, "wobblization", that produces a jet that is probably spiraled into a helical pattern. The extreme particulate jet behavior appears to be related to the brittle nature of glasses observed at lower temperatures and pressures. The ductile jet behavior appears to be associated with higher pressure and resulting glass jet temperatures. This observed ductile behavior is believed to be a result of traditional glass softening at elevated temperatures. The radially dispersed jet behavior appears to be associated with the classical observed behavior resulting from supersonic flow conditions in the jet formation region. Radial dispersion can vary from slight hollowing, bubble jets to complete radially dispersed droplet jets. C1 [Baker, E.

In order to evaluate the performance of a system, its effectiveness, and impact, Monte-Carlo analysis is performed using empirically derived random variable distributions. Due to the complexity of the GN&C systems, typical methods of linearization and closed form solution evaluation do not provide adequate results when determining the key parameters for measuring a systems overall performance. Since reliance on traditional methods is not adequate, Monte-Carlo analysis is performed with thousands if no hundreds of thousands of iterations. This analysis takes an immense amount of time, so utilization of this process during the design phases is used sparingly. When designing a control system, its robustness is hart to determine without performing this critical analysis. Through parallization, this process can be run independenlty on many processors simultaneously which in-turn reduces the runtime and allows for quick evaluation of testing modifications and algorithm updates. By utilizing a small computing cluster and rapidly parallizing simulations, we can integrate the Monte-Carlo analysis within the design cycle and mitigate errors prior to any hardware builds or costly flight experiments.

Radar testing confirmed that the actual flight performance of the 2-fin flechette was superior to that of the 4-fin version, when both were stable. However, the radar tests also revealed inconsistent behavior for both configurations, with some shots exhibiting evidence of extreme yaw and very large velocity loss.

An extensive experimental program for the aerodynamic and flight dynamic characterization of 5.56-mm small-caliber ammuntion has been developed and executed to enhance the Army's understanding of the ammunition over its first 600 m of flight using simulated-range experiments. A flight dynamic characterization, to include yaw limit cycle, was accomplished to provide data for validation against real-range yaw limit cycle data. The validation of simulated-range yaw limit cycle will provide a basis for all future yaw limit cycle testing because while yaw limit cycle remains a critical design parameter, real-range yaw limit cycle testing is not a viable option.;D C1 [Silton, S.

This safety fan area was determined analytically based on the distance a ricocheted bullet can travel. This large safety fan imposes high monetary and scheduling costs on training missions and there is a concern that this safety fan is un-realistically large. An effort was undertaken to predict a more accurate safety fan using a finite element code to predict the ricochet angle, velocity and bullet deformation in combination with a 6 degree of freedom analytical code to predict ricochet travel. The combination of these two types of analyses in combination with a small series of tests to calibrate the models has given a much more accurate tool to predict the safety fan area for the 30mm target practice round.

The primer force diagnostic provides a unique real time measure of the pressure in the primer cavity. Although the response time is slightly slower than that of a modern high-performance piezoelectric pressure gauge due to the filtering by the mechanical motion of the primer material, response is sufficiently fast to show timing and amplitudes of events. Preliminary data have been taken using the force measurement and one pressure transducer. With this configuration, we have successfully documented the difference between standard #41 primers and a less brisant primer candidate replacement. We have observed that the pressure from a standard primer may sometimes exceed 30kpsi in the primer pocket. The addition of a second pressure gauge port opposite the one used in the preliminary data mentioned above, may allow measurement of the rate of propagation of the compressive wave from the primer function through the propellant bed. It is anticipated that these data, in conjunction with interior ballistics models, will give further insight into the role of the primer in packing the propellant bed and reducing gas permeability and flame spread.

We have developed several extrudable BKNO(3) based igniter materials that are more energetic, exhibit smaller ignition delay times, and are less sensitive than Benite, a common igniter employed in large caliber gun systems. We have demonstrated this via subscale testing, and static firing. High speed video during static testing has demonstrated significantly more consistent, intense, and rapid flame generation in comparison to Benite leading to improved ignition effectiveness.

The objective of the effort was to develop and demonstrate physics based modeling for explosive barrel cladding process design and optimization. The effort was focused on cladding modeling development, cladding process design and optimization. The effort applied high rate continuum modeling to physically model the process of barrel liner cladding. High explosive equations of state were being developed for the unique low density, low detonation velocity explosives used in the cladding process. A multi-scale dynamics approach was taken to address macro-scale liner cladding, as well as micro-scale clad welding dynamics.

Aside from dimensional specifications, case material properties have a significant impact on the cartridge case's ability to properly obturate and extract. For brass cartridge cases, material properties are typically characterized and controlled by case sidewall and head hardness measurements. This paper describes the development of an explicit-dynamic finite element model for Caliber .50 cartridge case pressurization, relaxation and extraction. Model results are validated against experimental measurements taken from fired cartridge cases possessing different case sidewall hardness profiles. The model predicts significant differences in weapon bolt load, residual case deformation, and extraction forces as a function of said profiles. Previously-identified weapon functioning issues resulting from inadequate cartridge case hardness profiles are explained and demonstrated analytically.

The pressure sensor requires a pressure tap (or a through-the-thickness hole) in the gun breech. A pressure tap can be a crack initiation site. The pressure tap in a 40-mm gun breech was evaluated for critical flaw size and fatigue life. Critical flaw size was estimated using the Extended Finite Element Method (XFEM) capabilities in the general purpose finite element program ABAQUS. Fatigue analyses were completed using Linear Elastic Fracture Mechanics assumptions. Both efforts used breech pressure versus time data collected at Los Alamos National Laboratory (LANL). This paper will discuss the impact of breech pressure on the pressure tap and sensor interface as well as the results of the finite element studies. Results predicted greater than 1000 cycle design life of the breech with a pressure tap. Results are consistent with the 150+ successful shots that have been completed and the 1000+ shots completed on a similar breech with similar pressure taps. C1 [Weaver, C. M.; Cordes, J.

The analysis accounts for ply-by-ply variation of material properties, ply orientations, and temperature gradients through the thickness of composite cylinder subjected to mechanical and thermal loads. Fiber reinforced composite materials generally illustrate extreme anisotropy in viscoelastic behavior. Viscoelastic effects of the composite can result in a drastic change of stress and strain profiles in the cylinders over a period of time, which is critical for structural durability of composite cylinders.
