Abstract:40094 November 8, 1996
Of all the applications in which scintillators are used, none puts more rigorous demands on the material than high energy physics. The high radiation fluxes characteristic of these experiments requires both… more
Abstract:Incomplete combustion in diesel engines are the source of many problems, including pollution, low efficiency, and reduced performance. In particular, diesel engines are the focus of much work in the area of improved combustion efficiency. While diesel engines do not exhibit high hydrocarbon and… more
Abstract:Concerns about health and environmental hazards associated with chemical spraying, as well as the rising cost of farming, madate that chemical application becomes more efficient and increasingly precise. It is important to know immediately if any nozzles have become partially clogged or ceased… more
Abstract:The objective of the proposed research is to develop a multi-axial balance, based on measurement of bulk-birefringence that develops in selected structural members as result of forces and moments applied. The proposed concept will make possible a balance design that is inherently more rigid, since… more
Abstract:The materials used in current thruster technology meet the performance parameters and environmental constraints needed for missile and space defense with difficulty at best and even then only with a high penalty in cost and weight. Spacecraft chemical propulsion systems with higher performance… more
Abstract:Divert propulsion systems are relying on ceramic matrix composite (CMC) thrust chambers to provide the high performance capabilities required by BMDO defensive missiles. Although the high temperature and toughness properties of ceramic matrix composites (CMC) have made them leading candidates for… more
Abstract:The proposed work addresses the generic need for more flexible methods of fabricating complex-shaped, three demensional solid objects from refractory structural materials. The proposed technology will enable fabrication of complex-shaped refractory metal components which cannot be made using… more
Abstract:The present focus for light weight body armor requires that materials properties are optimized and that new and innovative techniques are incorporated to achieve the required ballistic performance and make these materials conformable to the body shape. Through the lamination of ceramic tapes,… more
Abstract:Visidyne has discovered a now approach to determining whether or not an acoustic contact is submerged. Our approach has distinct advantages over previous methods; these add up, ultimately, to a higher degree of automation (at equal or better performance) and therefore a reduction in the cost of… more
Abstract:One of the most challenging problems in adding realism to the battlefield environment in DIS Exercises is treatment of the dynamic physical materials and processes resulting from battlefield munitions (i.e., battlefield smoke and dust, blast and shock damage to buildings, cratering of terrain and… more
Abstract:The objective of the proposed effort is to design an all solid-state, eye-safe (1.5 um) laser that will abe superior to existing eye-safe lasers in terms of power, efficiency, cost, and beam quality. The proposed laser system is based on solid-state Raman shifting of Nd:YAG laser radiation using… 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.
