Abstract:Complex skin defects, including burns and trauma, represent a major medical problem affecting both military and civilian populations. In recent military engagements, burns account for approximately 5% of combat casualties. Furthermore, approximately 1.25 million Americans each year require medical… more
Abstract:Many detectors - including solid-state particle detectors, microchannel plates, and photodiodes - output small current signals that require amplification and conversion to a voltage. Current-to-voltage converters (I/Vs) are widely utilized in experimental and commercial applications for this task.… more
Abstract:Vacuum glazing has been on the market for over a decade, but its performance is poor, and its cost too high for wide adoption. Both issues stem from the use of a hard glass edge seal, which requires a high temperature manufacturing process, and which does not flex to accommodate outer pane… more
Abstract:The desire and benefit to improve the environment through the use of advanced electric drive vehicles is hampered by the high cost and associated manufacturing hazards associated with the manufacture of lithium ion batteries. The use of solvents in the lithium ion battery manufacturing process… more
Abstract:We propose to design and implement a query-based approach to interoperable modeling and simulation of composite material structures, that usually contain the manufacturing recipe within their design. In Phase I, we established the feasibility of the approach using a demonstration scenario of CAD/CAE… 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.
