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
Abstract:BIOFIELD CORP. INTENDS TO DEVELOP AND TEST A NON-INVASIVE, COST-EFFECTIVE METHOD FOR BREAST CANCER SCREENING. THE TECHNOLOGY INVOLVES SCANNING OF ELECTRICAL SIGNALS FROM THE BREAST SURFACE. THE SPECIFIC AIMS ARE TO DEVELOP THE HARDWARE AND SOFTWARE FOR SUCH AN APPLICATION AND TO TEST THE METHOD ON… more
Abstract:THIS RESEARCH IS DESIGNED TO DEVELOP A SPECIALIZED SYSTEM CALLED TELEMINDER-TBC(TUBERCULOSIS CARE) FOR USE WITH OUTPATIENT POPULATIONS MOST AT RISK FOR TUBERCULOSIS, I. E., RACIAL AND ETHNIC MINORITIES, RECENT IMMIGRANTS, THE ELDERLY, AND HIV INFECTED INDIVIDUALS. TELEMINDER-TBC IS DESIGNED TO… more
Abstract:LEADING SCIENTISTS AND EDUCATORS HAVE STRESSED CRITICAL THINKING PROBLEM SOLVING AS TOP PRIORITIES FOR SCIENCE EDUCATION. A NEGLECTED ASPECT OF THIS BROAD AREA IS THE ABILITY TO MAKE GOOD DECISIONS THROUGH LOGICAL HABITS OF THOUGHT RELATING KNOWLEDGE, UNCERTAINTY AND HUMAN VALUES. SUCH SKILLS ARE… more
Abstract:IN TIMES OF DISASTER, OLDER PEOPLE SUFFER MORE DEATH, INJURY, FINANCIAL LOSS, AND STRESS THAN YOUNGER PEOPLE. THIS PATTERN OF NEGLECT CAN BE REDUCED BY IMPROVING COMMUNICATIONS BETWEEN COMMUNITY ELDERS AND AGENCIES PROVIDING EMERGENCY AND DISASTER RELIEF SERVICES. OUR LONG-TERM OBJECTIVE IS TO… more
Abstract:IN CURRENT AGRICULTURAL SPRAYING, LESS THAN 20% OF PESTICIDEREACHES THE INTENDED PLANT; MOST DRIFTS OR DEPOSITS ON THE SOIL, RESULTING IN ECONOMIC LOSS AND ENVIRONMENTAL HAZARD. SPRAY REACHING PLANTS IS OFTEN WASTED BECAUSE OF POOR PLACEMENT OF DROPLETS. EXCESS PESTICIDE DEPOSITS ARE PLACEDON UPPER… more
Abstract:THE AIM OF THIS PROJECT IS TO DESIGN A NEW MODULE FOR THE FIRM'S RASTER-BASED IMAGE PROCESSING AND GEOGRAPHIC INFORMATION SYSTEM (GIS) SOFTWARE. THE CONCEPT WILL BE USEDTO ENHANCE STANDARD DIGITAL VECTOR LAND-USE MAPS USING A KNOWLEDGE-BASED EXPERT SYSTEM THAT ACCESSES AVAILABLE GIS DATA SOURCES,… more
Abstract:GUIDED SYSTEMS TECHNOLOGIES PROPOSES TO APPLY AN INNOVATIVE COMBINATION OF INDIVIDUAL BLADE CONTROL CONCEPTS, AND EMERGING TECHNOLOGY FOR BLADE ACTUATION USING SMART MATERIALS, TO ACHIEVE DRAMATIC REDUCTIONS IN ROTOR SUSCEPTIBILITY. IN PARTICULAR, CONTROL INPUTS WILL BE TAILORED TO SPECIFIC MISSION… 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.
