Abstract:AstroPower is developing a highly sensitive UV detector based on epitaxial AlGaP/GaP heterostructures, a promising new material system for ultraviolet detectors. Detecting ultraviolet light is important to spectrophotometry, astronomy, high-energy physics, medicine, UV curing, photoresist exposure,… more
Abstract:AstroPower is developing a new process for the growth of large area, thin film 3C-SiC using a proprietary deposition technique followed by liquid phase epitaxy (LPE). Successful development of the growth process will provide high quality, thin film SiC in typical silicon wafer areas, allowing… more
Abstract:AstroPower will develop a two-junction monolithic tandem solar cell composed of (AlxGa1-x)0.51 In(0.49)P, which is lattice matched to GaAs, as the top cell in a three-junction, two-terminal tandem solar cell. This new tunable bandgap Al-Ga-In-P material is capable of current matching in a… more
Abstract:1 New concepts in optical computing and optical interconnects require hardware developments of generic, compact, multi-element LED source array. A two dementional array of individually-addressable Light-emitting Diode optical emitters will be developed. An innovative CVD/LPE heteropitaxy technique… more
Abstract:THERE IS A MAJOR ARMY REQUIREMENT FOR REDUCING THE PHYSICAL SIZE OF TACTICAL HF ANTENNAS (FOR USE ON A VARIETY OF CARRIERS FROM TRACKED VEHICLES TO DRONES) FOR ELECTRONIC WARFARE APPLICATIONS WITHOUT DEGRADING CURRENTLY ACCEPTED PERFORMANCE AND STILL MAINTAINING THE SAME GAIN, FREQUENCY AND POWER… more
Abstract:THIS PROJECT WILL DEVELOP A RELIABLE, TECHNICALLY SIMPLE GEL ELECTROPHORESIS SYSTEM FOR IDENTIFYING MUTATIONS IN CHARACTERIZED GENES. THIS METHOD WILL DETECT SINGLE-BASE CHANGES IN PCR AMPLIFIED GENOMIC DNA AND WILL FACILITATE SCREENING FOR DISEASE RELATED MUTATIONS. AS THE NUMBER OF CLONED GENES… more
Abstract:FUTURE MILITARY SYSTEMS WILL HAVE AN INCREASING NEED TO ACHIEVE A HIGHER AND MORE COMPLETE LEVEL OF SENSOR FUSION THAN CURRENTLY EXISTS. THE RATIONALE FOR SSNSOR FUSION IS GENERALLY WELL ACCEPTED AND RELATES TO PERFORMANCE, RELIABILITY, MODULARITY, AND EXTENSIBILITY. IT IS NOW DESIRED TO INTEGRATE… more
Abstract:Direct digital modulation for hardware-in-the-loop simulations of airborne radar systems is currently digital multiplier limited. A digital multiplier technology which can support 8-bit modulation rates of at least 250 MHz with a maximun incurred signal delay of 100 nanoseconds is required. To… more
Abstract:RESEARCH TO DEVELOP A FLEXIBLE FLATJACK FOR THE QUANTITATIVENONDESTRUCTIVE EVALUATION OF MASONRY IS PROPOSED. A FLATJACK IS A HYDRAULICLY PRESSURED BLADDER EMPLOYED TO MEASURE IN-SITU STRESS AND MODULUS. THE RESEARCH WILL REQUIRE DEVELOPMENT AND APPLICATION OF FIBER-REINFORCED FLEXIBLE COMPOSITE… more
Abstract:THIS PROPOSAL SEEKS TO ESTABLISH THE FEASIBILITY OF APPLYING NEWLY DEVELOPED MORPHOLOGY-BASED ATR ALGORITHMS TO THE IRST TARGET DETECTION AND TARGET/CLUTTER DISCRIMINATION PROBLEM. THE IMPORTANCE OF THIS UNIQUE APPROACH IS TWOFOLD. FIRST, DETECTION PERFORMANCE CAN BE DRAMATICALLY IMPROVED (OVER… more
Abstract:THE PROPOSED RESEARCH WILL INVESTIGATE EFFICIENT FRACTAL-BASED TECHNIQUES FOR GENERATING WIDE AREA SAR IMAGERY OF NATURAL CLUTTER TO SUPPORT WEAPONS SYSTEM TESTING. THE COMPUTER GRAPHICS FIELD HAS DEMONSTRATED THE USE OF FRACTALS FOR RAPIDLY CREATING VISUALLY REALISTIC BACKGROUND SCENES. FOR WEAPON… more
Abstract:A method is proposed for calculating the vertical and horizontal forces and moments developed by a ducted propulsor on a submerged vehicle operating at a small angle of attack. The key element of the computational method is the development of an equivalent actuator disk representation of induced… more
Abstract:THE DEVELOPMENT OF AN ANALYTICAL TECHNIQUE HAVING HIGH DEPTH AND LATERAL RESOLUTION, VERY HIGH SENSITIVITY AND SELECTIVITY, VERY HIGH (>10 X12) DYNAMIC RANGE, HIGH QUANTITATION ACCURACY, AND INDEPENDENCE FROM MATRIX EFFECTS ON SURFACES AND AT INTERFACES, IS CRITICAL IN MANY AREAS OF RESEARCH,… more
Abstract:THE OBJECTIVE OF THE PROGRAM IS TO DESIGN RAKE PROBES THAT CAN ACCURATELY MEASURE AND MAP ARC-JET EXIST PLANE FLOW QUANTITIES. THREE RAKE PROBES SHALL BE DESIGNED THAT CAN MAP OUT THE AERODYNAMIC PROPERTIES OF THE TEST SECTION IN HIGH-ENTHALPY/HIGHPRESSURE ARC-JETS. THE FIRST PROBE SHALL BE A… 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.
