Abstract:THIS PROJECT LAYS THE FOUNDATION FOR THE DEVELOPMENT OF A PRACTICAL THERMOELECTRIC COOLER THAT WILL OBTAIN COLDER TEMPERATURES THAN 160K AND/OR HIGHER EFFICIENCIES THAN CURRENT COOLERS WHEN OPERATING BELOW 200K. THE IMPROVED THERMOELECTRIC COOLER WOULD USE N-TYPE BI-SB, PRODUCED THROUGH POWDER… more
Abstract:THE UTILITY OF RELIABLE, SOLID-STATE, THERMOELECTRIC COOLING TECHNOLOGY CAN BE EXTENDED TO CRYOGENIC TEMPERATURES (77 DEGREES K) THROUGH THE USE OF NEW THERMOELECTRIC MATERIALS. A UNIQUE AND INNOVATIVE APPROACH TO IMPROVED THERMOELECTRIC MATERIALS CAPABLE OF TRIPLING THE THERMOELECTRIC FIGURE OF… more
Abstract:THE PROPOSED RESEARCH BUILDS UPON THE CONTRACTOR'S PROPRIETARY NEURAL NETWORK SPACE-TIME MEMORY, THE PARAMETRIC AVALANCHE, TO DETERMINE A SET OF DESIGN CHARACTERISTICS FOR NEUROCOMPUTING ARCHITECTURES THAT WILL EFFECTIVELY SUPPORT REAL TIME ACQUISITION AND TRACKING OF MULTIPLE TARGETS USING MULTIPLE… more
Abstract:The objective of this Phase I investigation is to develop candidate designs for a prototype prevailing torque nut with a locking mechanism that can be reliable re-used. The current prevailing torque nuts used in military aircraft are a nuisance in the respect that they will provide adequate locking… more
Abstract:THE RESEARCH PROPOSED IN THIS DOCUMENT ADDRESSES SOLDER APPLICATION TO PRINTED CIRCUIT BOARDS AND OTHER SUBSTRATES WITH A NEW FLEXIBLE APPROACH THAT COULD BE EMPLOYED IN NUMEROUS APPLICATIONS, DIRECTED APPLICATION OF MOLTEN SOLDERDROPLETS, ON THE ORDER OF 30-100MUM, USING INK-JET PRINTING TECHNOLOGY… more
Abstract:CONTEMPORARY RESEARCH ON NEURAL NETWORKS AND NEURAL SYSTEMS DEMANDS VERSATILE TECHNIQUES FOR SAMPLING ELECTRICAL AND BIOCHEMICAL PARAMETERS OF NEURAL ACTIVITY. AN ESPECIALLY PRESSING TECHNICAL PROBLEM IS THAT OF MEASURING MULTIPLE CHEMICAL OR ELECTRICAL CHANGES SIMULTANEOUSLY WITHIN A FUNCTIONING… more
Abstract:A NOVEL HELIUM MAGNETOMETER WILL BE EXAMINED FOR OBSERVATIONOF MAGNETIC FIELDS OF PLANETS AND INTERPLANETARY SPACE. THE MAGNETOMETER EMPLOYS A DUAL MODE OF OPERATION, WITH A SINGLE, OPTICALLY PUMPED HELIUM SENSOR TO OBSERVE THE MAGNITUDE AND DIRECTION OF MAGNETIC FIELDS AS GREAT AS 10(5)NT. THE… more
Abstract:THE PROPOSED WORK REPRESENTS A NEW, INNOVATIVE APPROACH IN THE DEVELOPMENT OF IMPROVED HIGH RESOLUTION DISPLAYS. THE CORE FEATURE OF THIS NEW DISPLAY CENTERS ON CONSTRUCTION OF A REVOLUTIONARY NEW LIGHT VALVE WHICH COMBINES STATE-OF-THE-ART CAPABILITIES IN VLSI AND LIQUID CRYSTAL (LC) TECHNOLOGIES.… more
Abstract:THE PROPOSED WORK CENTERS ON THE DEVELOPMENT OF REVERSE MODEPOLYMER DISPERSED LIQUID CRYSTAL MATERIALS. THESE MATERIALS, WHICH WILL BE FABRICATED EITHER AS FILMS OR AS ENCAPSULATED DROPLETS, ARE RADICALLY DIFFERENT FROM OTHER LIQUID CRYSTAL DEVICES, INCLUDING NORMAL MODE POLYMER DISPERSED SYSTEMS.… more
Abstract:Powder Tech's technique facilitates the creation of a structural, metal matrix composite with previously unsurpassed strength-to-density ratios at elevated operating temperatures, and may be the single most important find to traditional powder metallurgy ever. This technique involves the coating of… more
Abstract:IN RECENT YEARS, A NUMBER OF ADVANCED PHYSICAL COAL CLEANING PROCESSES DESIGNED TO GENERATE EXTREMELY LOW ASH AND PYRITIC SULFUR CONTENT PRODUCTS HAVE BEEN INVESTIGATED. ALL THESE PROCESSES INCORPORATE FINE TO EXTREMELY FINE GRINDING OF THE COAL TO LIBERATE MINERAL PARTICLES, PARTICULARLY PYRITE,… more
Abstract:THE CLEAN AIR ACT AND ENVIRONMENTAL CONCERNS IN GENERAL HAVE PLACED INCREASING PRESSURE ON THE COAL INDUSTRY TO LIMIT THE SULFUR CONTENT IN THEIR CLEAN COAL PRODUCTS TO LEVELS THAT ARE SIGNIFICANTLY LOWER THAN PREVIOUSLY REQUIRED. TO CONTROL SULFUR CONTENT IN THE CLEANING PROCESS, IT IS FIRST… more
Abstract:THE LONG-TERM OBJECTIVE OF THIS RESEARCH IS TO INCREASE THE RETURN REALIZED ON INVESTMENTS IN NEW TECHNOLOGIES FOR PRESENTING HEALTH PROMOTION AND DISEASE PREVENTION INFORMATION. THE IMMEDIATE OBJECTIVE IS TO PRODUCE RELEABLE, EMPIRICALLY BASED, EASY-TO-USE SOFTWARE TO HELP DEVELOPERS AND INTENDED… more
Abstract:DIAMOND HAS EXTREMELY HIGH THERMAL CONDUCTIVITY, A LARGE BANDGAP, HIGH CARRIER MOBILITIES AND LOW NEUTRON AND IONIZING RADIATION DISLOCATION CROSS SECTIONS. THESE PHYSICAL PROPERTIES MAKE IT AN IDEAL MATERIAL FROM WHICH TO CONSTRUCT ELECTRONIC DEVICES FOR HIGH TEMPERATURE, HIGH FREQUENCY AND/OR HIGH… more
Abstract:The physical and chemical properties of ultrasmall particles (in the range of 1 to 10 nm) differ greatly from those of bulk solids. For example, the melting point of 3 nm CdS has been reduced by almost a factor of five from bulk CdS. Bandgaps may be increased along with various activation energies.… more
Abstract:Diamond exhibits physical properties that make it an ideal material from which to construct electronic devices. A major obstacle to the use of diamond as a naturally insulating thermal management material is the lack of a method for growing large area thin films of diamond at low temperature on… 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.
