Abstract:An open problem confronting Uninhabited Tactical Aircraft (UTA) is the control concept for their successful operation in combat. Unlike reconnaissance UAVs, it will not be practical to operate UTAs with fully pre-programmed missions nor will it be possible to continuosly fly with them from remote… more
Abstract:The specific problem addressed by the proposed research is the development of a scanner for storage phosphor plates with significantly better positional and intensity accuracy than the current state of the art. The new scanner will be based on the use of a "scanning head" scanning approach which is… more
Several advancements are needed to improve the efficiency and accuracy of hard rock drilling. Of particular interest are bottomhole assemblies (BHAs) which can grip the borehole wall in order to provide a platform from which torque and compressive force can be applied to the… more
Abstract:We propose to apply a non-intrusive embedded acoustic sensor concept, which has been used successfully in reentry vehicle aerodynamics applications for detecting exterior flow conditions to penetrator munitions for detecting various media and buried structures during penetration. This effort… more
Abstract:The objective of the Phase I effort is to demonstrate an experimental/numerical technique for formulating penetration equations and identifying pertinent material parameters to be used in those equations. Although penetration equations for isotropic metals are well developed, such equations are not… more
Abstract:While the Internet may promise the potential of increased access to services and information, obstacles make access to such technology by rural businesses, educators and individuals difficult.
Much research has been conducted about bringing Internet services into K-12 education, and projects have… more
Abstract:With the advent of widely available PC technology, crash safety information can be cost-effectively disseminated to millions of people in an engaging and educational way. With an enticing and informative PC application, data about damages, costs, injuries and death can be personalized and grasped… more
Abstract:Emerging high-speed networking technologies have the potential to dramtically increase access to information in many fields such as education, defense, government information dissemination and health care. However, there are several technical issues that need to be addressed to harness this… more
Abstract:The complexity of systems design has dramatically increased over the past decade. Developers are responding to the complexity by modeling such systems in order to further understand, characterize, or analyze their behavior. Any model-based application may actually utilize multiple models which… more
Abstract:The information processing tasks associated with defense application, such as Automated Target Recognition (ATR), have very diverse computational requirements that result in different needs for computing systems capabilities. A "heterogeneous" parallel computing environment provides a variety of… more
Abstract:Codling moth, Cydia pomonella, is a major exotic pest of walnuts, apples and pears in California. Current control practices, using the application of conventional pesticides, are costly, toxic and declining in effectivenss. Of additional concern in California is that many walnut orchards are… more
Abstract:Presently available commercial and military sonar systems can detect, localize, and classify buried underwater mines and hazardous waste containers only under the most benign environmental conditions. Even then, the mapping rates which are realized are too small for the areas which must be surveyed… more
Abstract:Unusually active nanosize metal powders have been in development and production in Russia since 1975, and they are now being manufactured in the United States. Their size, approximately 50 to 100 nanometers, provides promise for sub-micron size features. The powders have significant stored energy… more
Abstract:This proposal describes new low cost, low risk semiconductor-based approaches to fuze trigger circuit technology. These innovative approaches build on the promising new technology platform developed by ARIA as part of earlier SBIR research. ARIA's technology platform, initially developed for… 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.
