The starshade acts as an external occulter to suppress the incoming… more
Abstract:Unmanned Aerial System (UAS) operation represents a stressful, cognitively challenging domain where operators are routinely subjected to both occupational and combat stressors and performance failures can have catastrophic effects. Effective performance in such conditions has many dimensions,… more
Abstract:The synthesis of ammonia through nitrogen fixation is a vital component to all plant life and the world economy as a fertilizer and commodity chemical. The global industial production of ammonia exceeded 140MM tons in 2009 and is expected to grow to 160MM tons by 2020. Most ammonia,>90% is… more
Abstract:Recently, the availability of the high performance rare earth based magnets (Nd-Fe-B and Sm-Co) was jeopardized due to the Chinese monopoly of rare earth production, which undermines our national security and competitiveness in the defense and clean energy sectors and creates a strategic… more

Abstract:ABSTRACT: Over the past 30 years, night vision goggle technology has enabled American fighter pilots to"own the night". As night vision goggle technology has matured, we have required more from pilots and are asking them to fly multi-role extended missions that may occur in degraded… more
Abstract:ABSTRACT: Digital binocular helmet-mounted display (HMD) systems are now available that allow high resolution wide field-of-view (WFOV) digital imagery to be displayed on high resolution microdisplays. These digital HMD systems require sensor preprocessing, optical distortion correction, and image… more
Abstract:ABSTRACT: Currently tactical Head up Displays (HUD) are expensive both in cost of acquisition and Life Cycle Cost. In addition, retrofit of a more capable HUD into an existing airframe is complex and the bulk of the HUD competes with other display systems for valuable cockpit volume. The objective… more
Abstract:ABSTRACT: The military is constantly looking to improve night vision goggle performance. There are many components to optimize but one that is often overlooked is faceplate. The faceplate serves both as a substrate for the photocathode as well as a method for sealing the tube for high vacuum. It… 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.
