Abstract:ABSTRACT: RJ Lee Group, Inc., in partnership with experts from Hamler Test and Analysis, Inc., and in collaboration with GE Aviation, proposes to develop a Decision Support Tool (DST) to model the cumulative effects on component service life by CMAS (calcium-magnesium-aluminum-silicon oxide) on jet… more
Abstract:The need exists for an autonomous Tactical Decision Aid (TDA) tool which can be used to optimize the effectiveness of Multi-Static Anti-Submarine Warfare (ASW) mission performance. The tool must make use of the most up-to-date and accurate environmental data obtained in real-time over a network… more
Abstract:U.S. Navy ASW aircraft deploy sonobuoys across a mission field. The aircraft must then stay on-station for the duration of the mission to monitor, command, and received data from the deployed sonobuoys. This requires a clear and uninterrupted channel of communications during all command downlink and… more
Abstract:An innovative, new adaptive signal processing solution is proposed for mitigation of the impact that wind turbine clutter has on airborne radar performance. Electromagnetic simulations are used to predict radar returns in the presence of wind turbine scattering, terrain multipath, and clutter from… more
Abstract:Looking Glass is an immersive, story-driven game experience that enables computer science education for students K-12. It presents learning in a game-based series of challenging levels that permit a high degree of player choice in tailoring educational pr
Abstract:The frictional losses in a gear mesh can be reduced by including super-finishing in the final manufacturing process. Phase I simulation tests of a hypoid rear axle gear shows a reduction in traction coefficient of 50 percent from an"as ground"surface to a high quality super-finished… more
Abstract:ABSTRACT: Incomplete and inconsistent impregnation of fiber beds in composite material manufacture jeopardizes the performance of multiple aircraft platforms and substantially increases acquisition and sustainment costs for the Air Force. Current test methodologies are inadequate to address this… more
Abstract:Because Critical Program Information (CPI) is often embedded in Integrated Circuits (ICs), adversaries must now attack at the die level or through other intrusive means. As a result, Focused Ion Beams (FIBs) have become a preferred tool for reverse engineering. In Phase I, Nokomis demonstrated that… 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.
