Abstract:Recent research has shown that effective jammer and clutter suppression is best performed with fully space-time adaptive processing. However, allowing adaptive weights on every tap on every element is computationally prohibitive and requires too many samples to converge. Eigenvalue analysis shows… more
Abstract:GLUTARALDEHYDE-PRESERVED BIOPROSTHESES HAVE BEEN ASSOCIATED WITH IMPORTANT LONG-TERM CLINICAL PROBLEMS SUCH AS STENOSIS, BIODEGRADATION AND CALCIFICATION-INDUCED HEART FAILURE. AN ALTERNATIVE TO THE USE OF GLUTARALDEHYDE, WHICH CONSISTS OF CROSS-LINKING BIOLOGICAL TISSUE BY FORMING STABLE BONDS,… more
Abstract:BioTechnical Communications is proposing to develop a prototype for healthcare programming targeted to African-Americans, and to broadcast on Black Entertainment Television (BET), a targeted cable television network. BioTechnical Communications will be responsible for the accuracy of the technical… more
Abstract:We propose to develop ne%v methodolooy allowing non-technical planners to specify, generate, and solve multidimensional logistics network problems. Our approach is based on in- tegrating new generations of multidimensional spreadsheet software, mathematical programming languages, and ultimately… more
Abstract:Though allograft human aortic valves are preferred for transplantation by virtue of their lowthrombogenicity and immunogenicity, superior hemodynamic performance, and extended durability, onlyabout 2,000 per year are implanted due to limited donated heart supply. An acellular porcine heart… more
Abstract:This proposal is submitted by Johnson Research and Development Company, Inc., in collaboration with the Georgia Institute of Technoloqy. The proposed research comprises both analytical and experimental activities, including the construction and operation of a proof-of-concept experiment. The… more
Abstract:Combustion chemical vapor deposition (CCVDsm) which was invented by the principal investigator, is a high quality film deposition technique that can inexpensively and quickly apply yttria stablized zirconia (YSZ) and doped-LaCrO3 thin films in a continuous manner. This technology can be used for the… more
Abstract:A view of a model in simulation is the abstraction mechanism that allows the definition a new component in the simulation that is derived from other components. The objective similar to the case of database views which is to allow the extension and reorganization of a model without affecting the… more
Abstract:An intelligent nonlinear control methodology, based on an innovative combination of feedback linearization and artificial neural networks, is to be adapted to control remotely piloted helicopters. A mapping is derived which transforms a nonlinear dynamic model of the plant into a linear, time… more
Abstract:It is proposed that the wide range of nonmilitary applications for DoD UAVs be identified and assimilated into a representative set of mission profiles and vehicle specifications, to identify the DoD UAVs that could be used to conduct such missions and to meet such specifications, and to identify… more
Abstract:Few strategic decision-making tools are effective today in availability analysis. These tools adapt highly deterministic approaches, ignoring uncertainty and subjectiveness naturally existing when evaluating potential propulsion system technologies. Such approaches preclude the use of a rich source… more
Abstract:Radioimmunoassays make up a significant percentage of the immunoassays used in clinicallaboratories. Nonradioactive, immunometric or "sandwich" assays using enzymes for signal generation(EIAs) have generally replaced radioimmunoassays for high molecular weight analytes. Low molecularweight analytes… more
Abstract:IMPLEMENTATION OF AN INTEGRATED DETECTION SYSTEM FOR CONTAMINATION MONITORING OF RESPIRATORS HAS BEEN PROBLEMATIC. BECAUSE OF THE COMPLEX SURFACES, HAND MONITORING USING PORTABLE SURVEY INSTRUMENTATION HAS BEEN THE PREFERRED METHOD. HAND MONITORING IS COSTLY IN TIME AND OFTEN FAILS TO RELIABLY… more
Abstract:SUBSOILS FOR SUPPORT OF ROADWAY, AIRFIELD, AND PARKING AREA PAVEMENTS ARE BEING IMPROVED AND REINFORCED BY THE INCORPORATION OF A GRID OF SMALL DIAMETER, SHORT, STABILIZED, VERTICAL, GRANULAR COLUMNS. THE METHOD IS A SMALLER-SCALE VARIATION OF A PATENTED PROCESS TO REINFORCE BEARING SOILS BENEATH… more
Abstract:The objective of the proposed research is to develop a small, light-weight, broad-beamwidth, multi-octave antenna which has a useable gain of over 0 dBi and which can operate without degredation of these characteristic parameters in the presence of a 3.3 watt per meter-square power density. By using… more
Abstract:Wang-Tripp Corporation (WTC) prposes a six-month Phse I exploratiory research and development effort to design a UHF Satellite Communications (SATCOM) antenna for beyond-line-of-sight communications, and participation in Navy communications nets. Curretnly availabe UHF SATCOM antennas are unsuitable… 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.
