(AOS) has demonstrated with optical processing: aim point selection in visible imagery, in clutter; target recognition in infrared… more
Abstract:MOST MAJOR NEUTRON FACILITIES OPERATING IN THE U.S. WERE DEVELOPED TWO OR THREE DECADES AGO. TO MEET THE NEW CHALLENGES FOR MATERIALS AND BIOLOGICAL RESEARCH IN THE FUTURE, A NEW GENERATION OF NEUTRON FACILITIES WITH MUCH HIGHER FLUX AND WITH COMPATIBLE INSTRUMENTATION IS BEING CONSIDERED. THE… more
Abstract:BASED ON THE LASTEST ACHIEVEMENTS IN RADIATION DETECTION, A NOVEL IMAGING DETECTOR SITULTANEOUSLY RECORDING X-RAY IMAGING AT THREE SEPARATE ENERGIES IN PROPOSED. ACCORDING TO PRELIMINARY COMPUTATIONAL PREDICTATIONS THE DETECTOR IS EXPECTED TO HAVE EXCELLENT ENERGY SELECTION, EXCELLENT MEASUREMENT… more
Abstract:This research will substantially advance the state of the art in single-chip photodetector arrays. Advanced Photonix, Inc. manufactures unique large-area, single-element silicon avalanche photodiodes (currently 16mm active-area diameter,but potentially up to 75mm). The research will demonstrate… more
Abstract:Speech deception and voice "hijacking" techniques are now sophisticated beyond the ability of any single detection methodology. Deceptive speech detection requires an array of analysis tools to collectively provide an acceptable probability of detection. An effective Voice Authentication Monitoring… more
Abstract:OIL REMOVAL FROM VOLUMINOUS STREAMS IS DIFFICULT. RESEARCH IS BEING CARRIED OUT TO DEVELOP NEW BIOREMEDIATION TECHNOLOGIES TO SPEED UP THE DEGRADATION PROCESS FOR THE OIL EMULSIONS AND DISPERSIONS. THE TIME REQUIRED FOR OIL REMOVAL WITH TODAY'S TECHNOLOGIES IS UNACCEPTABLY LONG, POSING AN… more
Abstract:A TWO-DIMENSIONAL NUMERICAL MODEL BASED ON A HYBRID FINITE ELEMENT METHOD WITH MESH ADAPTATION IS PROPOSED TO CALCULATE GROUNDWATER FLOW AND POLLUTANT TRANSPORT IN UNSATURATED POROUS MEDIA. THE ALGORITHM IS MODIFIED TO ENHANCE COMPUTATIONAL SPEED AND STORAGE, AND INCORPORATES PETROV-GALERKIN… more
Abstract:The following proposal details an effort required for understanding the in-bore aerodynamic stability of sub-caliber projectiles in aero-thermal- chemical (ATC) guns in order to design stable projectiles. The ATC gun is based on the concept of a projectile traveling through the propellant and… more
Abstract:This proposal describes a novel, high thrust density Detonation Wave Engine (DWE) applicable to the Mach range of 0 to 3. The geometry of this novel engine concept naturally provides for integration into a new Combined Cycle Engine with Ramjets. The concept is an intermittent combustion jet engine… more
Abstract:An innovative actively cooled structure concept is proposed which integrates proven cooling techniques and state-of-the-art fabrication methods to extend the maximum combustor wall temperature, thereby reducing cooling requirements and aircraft weight while improving engine performance. Specifically… more
Abstract:X-RAY IMAGING AND INSPECTIONS PLAY AN INCREASING ROLE IN THE DEVELOPMENT AND IMPLEMENTATION OF MODERN MANUFACTURING TECHNIQUE. THE INCREASING DEMAND FOR HIGH-RESOLUTION INSPECTION AND FOR INSPECTION AS AN ADJUNCT TO CRITICAL MANUFACTURING STEPS HAS GENERATED A NEED FOR NEW, FLEXIBLE, COMPACT,… more
Abstract:THE OBJECTIVES OF THE PHASE I EFFORT ARE TO QUANTIFY THE EFFECT OF X-RAY SCATTER ON RADIOGRAPHIC IMAGE QUALITY, TEST SCATTER REJECTION APPROACHES, AND GENERATE A CONCEPTUAL DESIGN OF A SYSTEM WHICH WILL PROVIDE BETTER RESOLUTION, CONTRAST SENSITIVITY, AND DYNAMIC RANGE THAN IS CURRENTLY AVAILABLE… more
Abstract:DARPA AND THE U.S. SEMICONDUCTOR COMMUNITY ARE ACTIVELY DEVELOPING LASER-PRODUCED PLASMA (LPP) X-RAY SOURCES AS THE BASIS FOR X-RAY MICROLITHOGRAPHY EXPOSURE SYSTEMS. THESE LPP SOURCES WILL ALLOW THE CONSTRUCTION OF COMPACT EXPOSURE SYSTEMS THAT CAN BE EASILY INTEGRATED INTO EXISTING SEMICONDUCTOR… 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.
