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
Abstract:High speed, low cost optical self routing optical crossbar switches with gigabit data rates are key components in optical communication and routing systems. We propose to fabricate and study a monolithically integrated optical crossbar switch which will be inexpensive and high performance. This… more
Abstract:AT THE PRESENT TIME, ALL MATURITY SORTING OF FRUITS AND VEGETABLES, SUCH AS APPLES, PEACHES ANDTOMATOES, IS ACCOMPLISHED EITHER BY HAND, BY COLOR OR BY THE USE OF THE MAGNESS-TAYLOR . EACH OF THESE TECHNIQUES HAVE MAJOR DISADVANTAGES IN THE HIGH-SPEED MATURITY GRADING OF FRUITS AND VEGETABLES. THE… more
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
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.
