Abstract:The project goal is to build a software tool to predict man-made signals and RF noise levels at large distances (km"s) from the sources to enable management of the RF environment at DoD test ranges. These test ranges have a low level of man-made noise, which is critical for the testing of… more
Abstract:Diffusion barriers used in Nb3Sn wire are currently fabricated by wrapping Ta sheet into a tube with signifigant overlap. The result of current practice is non-uniform deformation in the Ta sheet as it thins by wire drawing because of non-uniform grain size and texture. In addition, a signifigant… more
Abstract:ABSTRACT: The work proposed here will apply an extensive suite of tools and technologies developed by SDL for automatic target recognition (ATR) using multi-mode LADAR data to aid analysts to exploit multi-mode LADAR data for combat ID. SDL has teamed with experts in Cognitive Task Analysis to gain… more
Abstract:The bandwidth of current and future image analysts is insufficient to ingest the vast quantity of data generated by staring sensing platforms. Because of this, signature exploitation algorithms need to play a role in the data processing chain to cue analysts to specific regions of interest within… more
Abstract:Using an information theoretic Global Image Quality Equation(GIQE), we map image formation parameters to National Image Interpretability Rating Scale(NIIRS) levels. These NIIRS levels are also projected onto PID derived from analysts and signature exploitation algorithms for various target sets.… more
Abstract:A new genre of sensing technology is being employed to develop reliable, low cost, pressure sensors that are able to make measurements at locations in aircraft turbine engines, such as P4, where it has not previously been possible to do so.
Abstract:This project will develop a robust, reliable and low cost networked sensor capability for advanced turbine engines and other applications. This system will enable pressure, temperature, vibration and strain to be measured in extremely harsh environments such as turbine engine combustors, enabling… more
Abstract:Shock Transients, Inc., (STI) will show feasibility of MPXI, an innovative liner material that releases energy in response to a strong shock stimulus but is otherwise safe and insensitive. STI's approach will be to analyze alternative MPXI blends and to test selected candidates for safety and… 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.
