Doyle at Trinity University using a rational approach employing molecular modeling and molecular orbital calculations. These catalysts show an extraordinary ability to enantioselectively catalyze a… more
Abstract:This project involves a study with a gas-injected plasma focus facility intended to develop the database to design and build an optimized 1-MJ focus. The ultimate objective is to demonstrate the feasibility and attractiveness of this concept for very high specific impulse space propulsion. Studies… more
Abstract:Liquid crystal-based sonosensitive plates will be investigated for rapid determination of spatial distributions of temporal average intensities for diagnostic ultrasound beams, including real-time imaging and Doppler modes. From such distributions, exposure parameters such as SPTA (spatial… more
Abstract:AN IMPORTANT COMPONENT OF ARCJET THRUSTERS IS THE INSULATOR HOLDING THE CATHODE BASE AND SEPARATING THE ELECTRODES. THE CURRENT BASELINE MATERIAL IS BORON NITRIDE (BN), WHICH IS WELL KNOWN FOR ITS HIGH ELECTRICAL RESISTIVITY AND HIGH THERMAL CONDUCTIVITY. HOWEVER, AT ARCJET OPERATING TEMPERATURE, BN… more
Abstract:An important component of arcjet thrusters is the insulator holding the cathode base and separating the electrodes. The current baseline material is Boron Nitride (BN), which is well known for its high electrical resistivity and high thermal conductivity. However, at arcjet operating temperatures,… more
Abstract:The addition of a high emissivity coating to the radiating surfaces of an arcjet thruster has been explored as a means to improve arcjet performance. At arcjet nozzle operating temperatures, the emissivity of an uncoated tungsten nozzle is approximately 0.4. When coated with a material having an… more
Abstract:Most women do not practice breast self examination (BSE) even though 90% of all lumps are identified by the woman and BSE has the potential for early identification of potential malignancies. Lack of confidence in being able to perform the procedure and perceived invulnerability to breast cancer are… more
Abstract:THERMOGEN, INC., WILL DEVELOP AN IN VIVO PROTEIN ENGINEERINGSYSTEM ALLOWING RAPID, RANDOM SHUFFLING OF PROTEIN DOMAINS TO PRODUCE NOVEL PROTEINS FORMED BY GENE FUSION. THIS SYSTEM WILL BE DESIGNED TO ALLOW GENERAL PRODUCTION OF CHIMERIC GENES WITH ALTERED FUNCTIONS, MAPPING OF FUNCTIONALDOMAINS IN A… more
Abstract:THE FEASIBILITY STUDY WILL BE IN EIGHT ELEMENTS WITH ELEMENT 1 BEING AN ANALYSIS OF CURRENT TRANSPORTATON PLANNING AND ENGINEERING SOFTWARE AND HARDWARE USE. DESIGN-COMPUTERS WILL BE IDENTIFIED IN THIS ELEMENT. IN ELEMENT 2, AN ANALYSIS OF DATA INPUT OPTIONS AND THEIR IMPLICATIONS FOR THE SOFTWARE… more
Abstract:THE PRINCIPAL OBJECTIVE IS THE COMMERCIAL DEVELOPMENT OF A VIRTUAL REALITY SIMULATOR TO ASSESS DRIVING PERFORMANCE IN PERSONS WITH VISUAL FIELD LOSS. THIS INTERACTIVE SIMULATOR WILL GIVE SUBJECTS THE SENSATION THAT THEY ARE DRIVING IN A VIRTUAL WORLD WITH THE USE OF WIDE- FIELD DRIVING SCENES,… more
Abstract:WIZDOM SYSTEMS, INC., A PIONEER IN THE DEVELOPMENT OF CIE/CIM SOFTWARE AND INTEGRATED METHODOLOGIES, PROPOSES FOR PHASE I TO DETERMINE SOFTWARE DESIGN REQUIREMENTS AND SPECIFICATIONS FOR WIZARD, A SOFTWARE ENVIRONMENT FOR INTEGRATED DESIGN AND MANUFACTURABILITY ANALYSIS (IDMA). WHEN COMPLETE, THE… more
Abstract:THIS RESEARCH DEVELOPS A FRAMEWORK FOR IDENTIFYING THE CRITICAL STRUCTURAL AND ENVIRONMENTAL FACTORS AFFECTING THE IMPLEMENTATION OF CALS TECHNOLOGIES AT SPOS AND ALCS. IT COMBINES A BOTTOM-UP VIEW OF THE ENVIRONMENTAL FACTORS AFFECTING WORK GROUPS' ACCEPTANCE OR REJECTION OF THOSE TECHNOLOGIES WITH… more
Abstract:ULTRASOUND FLOW MEASUREMENT AND PARTICULARLY COLOR FLOW MAPPING (CFM) SYSTEMS PROVIDE A VALUABLE TOOL FOR MEDICAL DIAGNOSIS. THESE TECHNIQUES PRIMARILY EXPLOIT THE DOPPLER EFFECT WHICH, DESPITE ITS GREAT SUCCESS, RESULTS IN TWO FUNDAMENTAL DRAWBACKS: (1) THE INABILITY TO MEASURE NONAXIALFLOW… more
Abstract:COMPUTED TOMOGRAPHY (CT) HAS BECOME INCREASINGLY IMPORTANT IN NONDESTRUCTIVE EVALUATION (NDE). INDUSTRIAL APPLICATIONSOFTEN REQUIRE VERY HIGH SPATIAL RESOLUTION. HOWEVER, THE FINITE WIDTH OF X-RAY SAMPLING LIMITS THE SPATIAL RESOLUTION. THE RESEARCH TO BE CARRIED OUT HERE WILL INVESTIGATE AN… more
Abstract:A HERMETICALLY SEALED, ALUMINUM-ELECTROLYTIC CAPACITOR WILL BE DEVELOPED AS A REPLACEMENT FOR TANTALUM CAPACITORS IN SPACE POWER SYSTEMS. THIS WILL SIGNIFICANTLY REDUCE POWER SUPPLY VOLUME AND WEIGHT. THESE CAPACITORS WILL OPERATE FROM -55 DEGREES CENTIGRADE TO 105 DEGREES CENTIGRADE, HAVE AN… more
Abstract:Strategic defense missions place a premium on the performance capabilities of onboard propulsion systems. An innovative technique for producing very high impulse at excellent thrust-to-weight ratios is known as laser-powered heat-exchanger propulsion. A remotely stationed high power laser is used to… more
Abstract:THE LONG-TERM OBJECTIVE OF THIS PROJECT IS TO DEVELOP AND MARKET COMPUTER-BASED INSTRUCTION PROGRAMS FOR TEACHING PERSONS WITH MENTAL RETARDATION/DEVELOPMENT DISABILITES. UNLIKE CURRENT PROGRAMS, THESE PROGRAMS WILL BE BASED ON WHAT THE EXPERIMENTAL LITERATURE SUGGESTS ARE MORE EFFECTIVE PROCEDURES… 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.
