CIRRUS will provide high-performance IR data management on the Secure… more
Abstract:Although footwear science has made considerable progress in the last decade, a performance gap continues to exist between standard issue military footwear and expedition footwear available on the commercial market. While the provision of in-shoe foot orthoses (ISFOs) is commonplace in commercial… more
Abstract:ABSTRACT: While developing any complex system, there are invariably tradeoffs among requirements; system performance, system architecture, cost, schedule, risk, standard compliance, and other factors that decision-makers need to address. A team of experienced system engineers can be leveraged to… more
Abstract:The CommLift Vertical Take-Off and Landing (VTOL) Unmanned Aerial Vehicle (UAV) is an alternate and novel approach to providing long range, over-the-horizon, communications for surface vessels; it uses a tethered electric UAV to carry a radio payload to suitable altitude, rather than an aerostat.… more
Abstract:ABSTRACT: The K-128 co-processor leverages insights from neuroscience to achieve superior performance. Unlike previous efforts along those lines, our approach is to create a software programmable co-processor that runs existing applications. One of the most salient characteristics of such a… more
Abstract:DRS Scientific proposes a new type of Acousto-Optic Tuned Filter (AOTF) polarimetric hyperspectral imager that is compact, rugged, and inexpensive, has no moving parts, is free of optical aberrations, and is fast and sensitive. It will cover 8-12 mm with 8 cm-1 spectral resolution or finer, and… more
Abstract:High performance motors, like those in hybrid electric vehicles, use high performance Nd-Fe-B magnets that contain up to 12 wt% of dysprosium (Dy) in order to increase the coercivity, and avoid demagnetization at elevated temperatures. However, the global rare earth elements (Nd, Dy, etc) supply… more
Abstract:Rare earth element (REE) based Nd-Fe-B and Sm-Co permanent magnets have been widely used because of their excellent magnetic properties. The applications of Nd-Fe-B and Sm-Co rare earth permanent magnets include hybrid electric vehicles (HEVs), power generator for wind turbines, high performance… 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.
