Abstract:Kinetic penetrators are currently made of depleted alloys of uranium or tungsten, which are both toxic heavy metals that are harmful to human health and the environment. Amorphous metals have the high strength, fracture toughness and surface erosion resistance needed to replace uranium and tungsten… more
Abstract:Air launched small unmanned aerial systems (SUAS) are limited by the current use of lithium-ion batteries (~150 Wh/kg) for power. To obtain a 4 hour run time of Group 1 SUAS a new battery technology is needed. TDA Research has discovered a fundamentally new battery cathode chemistry for high… more
Abstract:UV curable powder coating is an attractive technology which has far less environmental impact. Than conventional coating processes. Since powder systems are solvent-free they reduce air pollutants and reduce waste streams by eliminating the disposable of leftover wet paint. For these reasons the… more
Abstract:Bulk heterojunction organic photovoltaics (BHJ OPV) are a promising technology for converting sunlight into electricity because, in principle, they can be manufactured by coating a wide range of substrates by various solutions containing the organic (and inorganic) materials. However, current BHJ… more
Abstract:Today"s military must be highly mobile and carry all necessary equipment and supplies with them. A major limitation to mobility is the need to carry fresh water. Although there are military systems that are very effective in treating any source water for drinking, the size, weight, energy… more
Abstract:Vector-borne diseases plague hundreds of millions of people worldwide, including U.S. soldiers who operate abroad. To reduce the impact of vector-borne diseases on military operations, the Military employs the arthropod repellent system, which combines a permethrin-treated uniform with the use of… more
Abstract:Navy aircraft are equipped with an On-Board Oxygen Generation System (OBOGS) to supply the pilot and the crew with supplemental oxygen for high altitude operation. However, Navy aircraft are usually closely spaced while waiting for take-off from aircraft carriers, and the jet engine exhaust… more
Abstract:ABSTRACT: Generating track data from wide area motion imagery is an important first step in many exploitation tasks including high value target tracking, activity-based threat detection, and adversary network analysis. Tracker development to date has made significant advances, but there has been… 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.
