Bipolar battery designs are inherently the most volumetrically efficient batteries. Further, the elimination of the external intercell… more
Abstract:The goal of this project is to take silver-zinc battery technology to a new level for programs important to the Navy. Silver-Zinc batteries provide high energy and power density cells, and since the electrolyte is a water-based alkaline fluid, provide a comparatively safe battery. A disadvantage to… more
Abstract:ABSTRACT: Multi-sensor fusion is a key capability required for effective inferences for timely and accurate strategy and tactical planning. A multi-sensor fusion technology needs to appropriately weigh different image streams according to the uncertainties and errors across different inputs and… more
Abstract:Missile threats faced by our country are constantly increasing in lethality. The weapon used to counter such missiles is the kinetic interceptor. To work effectively, the reentry vehicle (RV) location must be precisely known. Confusing objects within the reentry complex make the key discrimination… more
Abstract:Key to phased arrays that can scale to high frequencies, bandwidth and large apertures is an architecture that enables full digital beamforming and large-array performance with minimum electronics per element. Out of the three proven beamforming methods for phased arrays: analog, conventional… 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.
