Abstract:PEOPLE WITH SEVERE DISABILITIES OFTEN FACE OBSTACLES HEALTH INSURANCE COVERAGE. SOME OBSTACLES ARE STRUCTURAL. FOR EXAMPLE, PRIVATE INSURERS SEEK TO EXCLUDE PEOPLE WHO ARE LIKELY TO INCUR HIGHER HEALTHCARE COSTS. PUBLIC PROGRAMS HAVE WAITING PERIODS AND RESTRICTIONS. THE AVAILABILITY OF BOTH PRIVATE… more
Abstract:FIBRIN SEALANT HAS MANY APPLICATIONS IN SURGERY. MIXING AND DELIVERY OF THE MAJOR COMPONENTS, FIBRINOGEN AND THROMBIN, IS CURRENTLY ACHIEVED USING TWO SYRINGES OR SPRAY CONTAINERS DISPENSED ALTERNATELY OR SIMULTANEOUSLY TO DELIVER FIBRIN SEALANT ONTO THE WOUND SITE. THESE SYSTEMS OF DELIVERY ARE… more
Abstract:The major factor limiting more widespread utilization of allogeneic veins in arterial bypass procedures is the recipients' immune response. The intimal endothelial cells appear to be the focus of this immune response, which results in loss of the intimal lining of the vessel lumen during the first… more
Abstract:COMMERCIAL MACHINE VISION WAS TRODUCED IN THE 1970S. TO THIS POINT, IT HAS NOT BEEM USED WIDELY FOR AUTOMATION IN MANUFACTURING DUE TO PERFORMANCE, COMPLEXITY, AND COST ISSUES. MOST COMMERCIAL VISION SYSTEMS ARE BASED ON VIDEO TECHNOLOGY WITH SEPARATE CAMERAS, FRAME GRABBERS, DIGITIZERS, AND… more
Abstract:A new textile process has been developed by Techniweave that employs multi-directional weaving in the fabrication of integrally woven, net shaped, complex components. The process has been demonstrated manually and has been shown through design of equipment to be feasible for an automated system. The… more
Abstract:IDENTIFICATION OF OPPORTUNITY: THE DEVELOPMENT OF A PRACTICABLE COMPOSITE GEOTECHNICAL MATERIAL CONSISTING OF SMALL DISCONTINUOUS REINFORCING ELEMENTS IN A COHESIONLESS SOIL MATRIX WOULD HAVE SEVERAL IMPORTANT APPLICATIONS, INCLUDING: BACKFILL FOR RETAINING SYSTEMS; BASE, SUBBASE, AND SUBGRADE… more
Abstract:The objective of this proposal is to demonstrate the feasibility of a new na resolution independent digital image compression technology in the area of real time compression for imagery including types generated by electro-optical, imaging infrared and millimeter wave sensors. The technology is… more
Abstract:A modern gas turbine engine such as the T800-LHT-800, which is to be used in the Army's Light Helicopter Experimental (LHX) Helicopter (now referred to as the RAH-66 Comanche), is among the most complex mechanical systems in use today. The parameters involved in diagnosing a fault are numerous and… more
Abstract:THE PROPOSED RESEARCH WILL DEVELOP A P-VERSION OF THE FINITE ELEMENT ALTERNATING METHOD (FEA). THE P-VERSION OF THE FEAM WILL ALLOW FOR THE ACCURATE CALCULATION OF FRACTURE PARAMETERS WHILE MINIMIZING THE MODELING EFFORT REQUIRED OF THE USER. THESE TWO BENEFITS WILL MAKE THE FRACTURE MECHANICS… more
Abstract:Current technology generally requires over 20 minutes to thaw/warm blood products to transfusion temperature, over 2 hours to completely freeze them, and reduces levels of clotting proteins in plasma. Current plasma bags are susceptible to low temperature fracture and frequently engender… more
Abstract:The Navy needs high energy density, safe, cost effective propulsion systems for underwater vehicles such as torpedoes, mines, and unmanned undersea vehciles. Systems currently in development (the PEM fuel cell and the aluminum-oxygen semi-cell) present an engineering challenge for scale-down to fit… more
Abstract:CURRENT PHASED ARRAY ANTENNA TECHNOLOGY UTILIZES DISCRETE DIGITAL OR ANALOG FERRITE PHASE SHIFTERS WHICH ARE HIGH COST AND RF POWER LIMITED WHEN IN THE TRANSMIT MODE DUE TO THE FERRITE SATURATION PHENOMENA. THE RESEARCH INVESTIGATES MACROMOLECULE AND ELECTROHEOLOGICAL SUSPENSIONS (ERS) AS AN… more
Abstract:THIS PROJECT WILL RESEARCH AND DEVELOP A FLOOR MONITOR FOR QUICK DETERMINATION OF RADIOACTIVE CONTAMINATION. THE MONITOR WILL UTILIZE A NEW PORTABLE TECHNOLOGY (INCLUDING SUPPORT ELECTRONICS). IT WILL HAVE THE CAPABILITY TO MEASURE BETA CONTAMINATION BELOW 5000 DPM/100 CM SQUARED WHEN AVERAGED OVER… more
Abstract:THE IMMINENT PHASE-OUT OF CHLOROFLUOROCARBON (CFC) REFRIGERANTS, IN PARTICULAR CFC-12, NECESSITATES IDENTIFICATION OF A SUITABLE ALTERNATIVE REFRIGERANT WHICH IS ATMOSPHERICALLY BENIGN. FOR MANY NEW EQUIPMENT APPLICATIONS, HFC-134A HAS EMERGED AS THE COMPOUND OF CHOICE DUE TO THERMODYNAMIC… more
Abstract:The standard 1553 Bus Controller and related engine test facility improvements will give NAPC a standard controller interface for testing engines equipped with FADECS. This effort will make hardware and software improvements to the operator station to add real-time data display, consistent operator… more
Abstract:The E-2C cockpit is currently equipped with analog instrumentation that is rapidly becoming unsupportable. Retrofit of the E-2C with flat panel, multi-function displays will resolve the supportability problem and will provide new mission support capability for the pilot and copilot. This new… 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.
