Abstract:Coronary heart disease accounts for the largest fraction of heart disease (the leading cause of death in the United States, affecting 12 million Americans) and has an annual cost to society that exceeds 110 billion dollars. There is a great clinical need for small diameter vascular artery grafts, as… more
Abstract:Applied Visions, Inc.(AVI) proposes to design a flexible, extensible application program inter-face (API) to commercial game engines that will provide Military Commanders, in a collaborative environment, with high-quality 3D visualization of the outputs of current and emerging C2 applications.
Abstract:Applied Visions, Inc. proposes to implement a flexible, extensible application program interface (API) to commercial game engines that will provide Military Commanders with high-quality, cost-effective, 3D visualization for use in current and emerging C2 applications. In Phase I we demonstrated… more
Abstract:Applied Visions, Inc.(AVI) proposes to leverage the technology of computer games to provide a powerful new method of visualizing the potential movement of ground targets and threats for op-erators of the Tactical Tomahawk Weapon Control System (TTWCS). Recent advancements in the multi-billion… more
Abstract:Ninety million American adults are deficient in the basic academic skills and problem solving competencies mandatory for success in today¿s workplace, resulting in unemployment, lowered productivity, and a shortage of qualified job applicants. This proposal is for the development of an… more
Abstract:DESCRIPTION (provided by applicant):
The long-term objective of our proposed research is to improve the early detection of lung cancer with chest radiography. Because chest radiography is used for such a wide variety of medical conditions, it is, by far, the most widely used diagnostic imaging… more
Abstract:New concepts and processing methods are needed to minimize high cycle fatigue and improve the damping behavior of monolithic titanium blades, vanes, and stators in high performance aircraft engines. Ceramic coatings applied by the plasma spray process have the potential to achieve the required… more
Abstract:Organic film polymers have been the dielectric of choice for high voltage, microsecond-discharge, high energy density capacitors. Electron traps normally found in these films limits their maximun voltage breakdown strength, engergy density, and dissipation. The objective of this proposal is to… more
Abstract:DESCRIPTION (provided by applicant): Production of a human apyrase protein as an antithrombotic agent is proposed. Thrombotic vascular occlusion due to abnormal platelet aggregation can lead to many diseases, including ischemic stroke, myocardial infarction, and restenosis after angioplasty or… more
Abstract:This Phase I and II SBIR will develop a user-friendly, run-time efficient software package dedicated to fitting and evaluating material models used in finite element codes like LS-DYNA. The software package will consist of a pre-processor, a core driver, and a post-processor. The pre-processor… more
Abstract:Poorly designed software and hardware systems are inconvenient at best; at worst, they are deadly. Usability evaluation techniques are designed to detect the potential for disasters and inefficiencies in poorly designed software. However, usability analyses are prone to failure due to conflicting… more
Abstract:We propose to develop a formal modeling software tool, Networks in Organizational Risk Management (NORM), that allows mission planners and organizational designers to create and experiment with organizational structures that minimize risk throughout the lifecycle of a system. The core of our… more
Abstract:The proposed effort aims to develop a system that is responsive to the military's needs to develop high performing multinational teams. The goal of the project is to develop a theoretically grounded, computer-based, multination team preparation system. We envision four interrelated components… more
Abstract:At the core of the Joint Force Air Component Commander's (JFACC) responsibilities is the need to understand the enemy, and the enemy's Courses of Action (COA) to enable successful operational decision-making and to develop a comprehensive air strategy for the Aerospace Operations Center (AOC). … more
Abstract:The objective of the proposed work is to integrate a normative engineering model into an intelligent tutoring system. This system will allow continuous performance monitoring and adaptation of training based on performance assessment. To accomplish these goals a model will be developed that will… more
Abstract:Methods are needed to understand, map, and measure the flow of information in C2 operations centers, taking into account the value of that information and the effects of information value on mission performance. The Knowledge-based Organizational Modeling Environment (KNOME) will combine task-based… more
Abstract:Recent efforts to automatically assess cognitive state from communications data using Latent Semantic Analysis (LSA) have produced impressive results (Gorman, Foltz, et al., 2003; Freeman, Thompson, and Cohen, 2000).

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.
