Abstract:Propagation Research Associates, Inc., (PRA) proposes to develop a software/hardware-in-the-loop (S/HWIL) capability that will implement the PRA Fast Algorithms for State Estimation (FASE) in a real-time environment. PRA developed a maximum likelihood estimator and a smoothed iterated filter to… more
Abstract:This Small Business Innovation Research (SBIR) Phase II project provides a unique and robust in-situ sensor for detection and control of impurities in microstructures and porous layers associated with manufacturing of semiconductor, MEMS, and emerging nanodevices. Use of impedance as a measure of… more
Abstract:We are developing a technology that embeds optical transceivers within backplane connectors. The goal is increase the bandwidth-density available in backplane (or board-to-board) connectors. The optical channels will operate at data rates of 10 Gbps on a 250 micron pitch. The first target… more
Abstract:This program adds built-in-test (BIT) functionality within multi-Gbps multimode fiber optic transceivers. The end goal is to develop transceivers capable of detecting and isolating fiber faults along the cable plant in a military environment. This Phase II effort will investigate a solution that… more
Abstract:The Cell processor architecture represents a significant shift in deeply coupled multi-core processor architecture. In the first implementation, the Cell Broadband Engine (CBE) has broken new ground in clock speed, density and power dissipation. By creating a design optimized for a specific class of… more
Abstract:We propose to develop and deploy a fully featured groupware platform for Rapid Expertise Aggregation Supporting Optimal Negotiation (REASON). REASON supports collaborative decision-making in dynamic, time critical situations. It presents a decision as a graph to improve coordination and reduce the… more
Abstract:Currently, automatic target recognition (ATR) evaluation techniques use simple models, such as quick-look models, or detailed exhaustive simulation. Simple models cannot accurately quantify performance, while the detailed simulation requires enumerating each operating condition. A need exists for… more
Abstract:The need for an information system that can obtain, deliver, and interpret information in a timely manner poses special problems for a highly dynamic mobile network with limited bandwidth and computing such as those found in dismounted warrior systems. Mobile agent architectures provide a framework… more
Abstract:The Army has engaged in a modeling and simulation effort to develop advanced technologies and tactics, techniques, and procedures (TTPs) supporting the transformation to network-centric warfare (NCW), which has culminated in the Modeling Architecture for Technology, Research, and Experimentation… more
Abstract:Recent military operations have demonstrated the use by adversaries of non-traditional or asymmetric military tactics to offset US military might. This issue has thus come into the forefront of national security. Rogue nations with links to trans-national terrorists have created a highly… more
Abstract:In a dynamic environment, it is important to support changing membership of groups, allow on-the-fly team building, and tailor information presentation. Information overload concerns in real-time interactions require presenting the right information to the right user at the right time. Our approach… more
Abstract:We propose to iteratively develop and evaluate audio cueing methods and integrate them into current Soldier systems using our testbed for Developing Audio alerts and Verbal cues for Improving Soldier Situational Awareness (DAVIS). The following four components characterize our effort: First, we… more
Abstract:Future naval operations in the littoral environment will make use of unmanned vehicles to support a range of operations, including intelligence, surveillance, and reconnaissance (ISR) and mine warfare. Many challenges that arise in pursuing such capabilities are rooted in the need for effective… more
Abstract:Organizations are increasingly providing networked access to mission-critical data, which promises unprecedented levels of coordination, distributed situation awareness, and distributed decision-making. However, decision-makers must be able to manage the masses of data available to them to maintain… more
Abstract:Today's information age relies on an extensive network of systems that form the Global Information Grid (GIG). The GIG is threatened by numerous entities including terrorist organizations, hackers sympathetic to America's enemies, criminal organizations, and nation states interested in cyber warfare… more
Abstract:We propose a system for real-time target identification and intent prediction of time critical targets (TCTs) from limited tracking data. Given the urgency of destroying or disabling an emerging target (e.g. a missile with a biological warhead), we focus on enabling preemptive action through… more
Abstract:As ever more data becomes available via faster, more reliable networks and advanced sensor platforms, there is an ever more persistent need for technology that will automatically find, synthesize, and contextualize data so that it may be used to support decision making. This need is especially… more
Abstract:Sensor technology has recently advanced to the point where it is has become quite feasible to use multiple sensor modalities on the same platform. However, methods for intelligently fusing the data from the disparate sensors into a more descriptive form have proven illusive. Fusion of features not… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
