Abstract:The Army needs a high energy, high power, linear x-ray tube to complete a large area, scanning computer tomographic inspection system. Available x-ray tubes cannot meet the high energy levels (>150kV) and power levels (>100mA) required to produce rapid, high resolution, tomographic images of large… more
Abstract:As an alternative to holographic laser radar, AMPS will develop a 3-D imaging concept that collects far-field intensity speckle patterns. This kind of measurement greatly relaxes the tolerances on vibration and coherence length. However, phase retrieval will be required to retrieve a 3-D image.… more
Abstract:A key component in the Alkali Metal Thermal to Electric Converter (AMTEC) is the electrode that is generally sputter deposited on the beta"-alumina solid electrolyte (BASE). Electrode deposition, as it is now practiced however, is a random process that covers active sites on the BASE and places many… more
Abstract:AMOCO PROCESS ACTIVATED CARBONS HAVE BEEN FOUND TO HAVE HIGH STORAGE CAPACITY FOR ALTERNATE FUEL VEHICLE ENERGY SOURCES SUCH AS HYDROGEN AND METHANE. NEARLY ALL OF THE GAS THESE CARBONS CAN STORE IS ADSORBED IN MICROPOROUS REGIONS WHERE PORE DIAMETERS ARE LESS THAN 40 A. HOWEVER, THE MICROPORES… more
Abstract:Safety-critical aerospace applications have become increasingly dependent on a software component. However, conventional approaches to increasing the software reliability of these systems have focused on purely programming aspects. While these methods can all lead to techniques which should minimize… more
Abstract:THERE IS AN INCREASED EMPHASIS ON THE ACOUSTIC SIGNATURES OF GROUND COMBAT VEHICLES DUE TO THE DEVELOPMENT OF NEW AND EFFECTIVE ACOUSTIC TARGET ACQUISITION SYSTEMS. DURING THE DESIGN STAGE OF A GROUND COMBAT VEHICLE, IT IS IMPORTANT TO REDUCE THE NOISE, EMITTED FROM STRUCTURAL COMPONENTS. THEREFORE,… more
Abstract:THE USEFUL LIFE OF ENGINE OIL IS KNOWN TO BE HIGHLY DEPENDENT ON FORMULATION AND THE ENGINE OPERATING MODE. CONSEQUENTLY, AN OIL-CHANGE INTERVAL BASED ON MILES TRAVELED OR ENGINE OPERATING HOURS DOES NOT NECESSARILY DEFINE THE IN-SERVICE QUALITY OF THE OIL. ONE PROBLEM IN PARTICULAR FOR DIESEL… more
Abstract:THIS PROJECT IS DIRECTED AT PRODUCING A GENERALIZED COMPRESSION MODEL FOR SYSTEMATICALLY TRANSMISSION OF VIDEO INFORMATION AT DECREASING DATA RATES WHILE MAINTAINING MAXIMAL INFORMATION. ALTHOUGH MUCH IS STILL UNKNOWN ABOUT THE HUMAN VISUAL SYSTEM, MAJOR PIECES OF THE PUZZLE HAVE RECENTLY BEEN… more
Abstract:MUCH RECENT WORK HAS BEEN FOCUSED ON ELUCIDATING THE POTENTIAL BENEFITS OF USING FUZZY LOGIC AND ADAPTIVE NETWORK DECISION MAKING METHODS. ADAPTIVE METHODS, LIKE BACK-PROPAGATION TAUGHT NEURAL NETWORKS, CAN MAKE IT POSSIBLE TO BUILD COMPLEX DECISION MAKING SYSTEM WHICH AVOID THE "EXPERT SYSTEMS"… more
Abstract:This proposal advocates the development of a tool to provide the Navy with a mechanism for conducting in depth evaluation of distributed human performance. This tool will produce a truthing, testing, and evaluation environment designed to meet the US Navy's progressively increasing requirements for… more
Abstract:We are proposing to develop Virtual Panoramic Vision Blocks (VPVB) to providing drivers of IVHS sensorized vehicles with a low cost means for gaining full driving situational awareness. This approach combines solid state sensors with advanced display technology and computing to implement an… more
Abstract:The Phase I goal is to build energy-efficient, compact femtosecond optical sources, and demonstrate diode-pumped lasers that can generate femtosecond pulses via self-modelocking. Only readily available 750-nm diode lasers will be used as pump source. Existing subpicosecond sources are complex… more
Abstract:AMONG THE STATED GOALS OF THE HUMAN GENOME PROJECT IS A DRAMATIC IMPROVEMENT IN DNA SEQUENCING TECHNOLOGIES AND CORRESPONDING REDUCTION IN COST PER FINISHED BASE SEQUENCED. RELATIVELY LITTLE ATTENTION, HOWEVER, HAS BEEN GIVEN TO THE PROBLEM OF ASSURING THE QUALITY OF THE RISING TIDE OF… more
Abstract:THIS PROJECT WILL EXPERIMENTALLY DETERMINE THE FEASIBILITY OF OBTAINING A HIGH-RESOLUTION, THREE-DIMENSIONAL IMAGE OF A SCENE USING AN INNOVATIVE, FOCAL-PLANE PROCESSOR TO PRODUCE A COMPACT OPTICAL SENSOR. THE INNOVATION IS IN THE GATING OF THE IMAGE INTENSIFIER TO DEMODULATE AN AMPLITUDE-MODULATED… more
Abstract:The proposed work investigates the feasibility of designing and building a high resolution spectroradiometer and integrating it with the NASA-owned Thermal Infrared Multispectral Scanner (TIMS). A limiting factor in the analysis of airborne multispectral thermal infrared imagery, such as from TIMS,… 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.
