Abstract:An integral component of many NASA missions involves remote sensing of the environment, both terrestrial and celestial. This is a challenging problem, since quantities of interest typically can not be directly measured but instead must be inferred. These inferences are made by solving inverse… more
Abstract:Active flow control using dielectric barrier discharge (DBD) plasma actuators is an attractive option for both reduction of complexity of aircraft systems required for off-cruise operation and increasing reliability of future hypersonic vehicles. However, development of DBD plasma actuators has been… more
Abstract:The successful operation of the Department of Energy X-ray light sources, free electron laser, and linear accelerator facilities depends on providing reliable photocathodes for generation of low emittance, high-brightness electron beams using conventional lasers. Experiments on GaAs-based… more
Abstract:Bottlenecks for instrument scientists currently lie in computational and data workflow complexities, and a lack of tools that allow real-time refinement to occur while samples are still in the instrument. Using the Genetic Algorithm Driven Decision Support System (GADDSS) the instrument user can… more
Abstract:Advanced visualization has become a ubiquitous tool in science, as a way to accelerate discovery and as a productivity tool for debugging scientific software. Unfortunately, visualization tools presently lack the ability to represent edge-centered, face-centered and other types of staggered data,… more
Abstract:Millions of dollars have been spent on the development of numerical software libraries within the Departement of Energy. While they are used extensively in academia and government, their adoption into industrial codes is less prevalent. The cutting ede capabilities offered by these packages,… more

Abstract:Antennas optimized for free space environments often have sub-optimal performance when placed in an in-situ environment. Nearby structures can alter the radiation pattern of the antenna or conversely the antenna can alter the radiation pattern of nearby antenna. In either case, there is a need to… more
Abstract:Each year, over 115,000 patients in the US need to have their diseased heart valves replaced with artificial devices. Although bioprosthetic valves are considered ideal, they wear out in about 15 years and are thus used primarily in the elderly who are notexpected to outlive the valve. Younger… 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.
