Abstract:Long term objective is to purify DNA of fetal origin, starting with a sample of maternal blood. Thtechnology to be used with a variety of Diagnostic Methods including Polymerase Chain Reaction (PCR)Genomic Hybridization (CGH), Electrophoresis. The whole human genome becomes analyzable for a… more
Abstract:Reconnaissance and surveillance missions, using small robust spacecraft, may require that sensors be rapidly positioned to suit the specific mission requirements. These maneuvers are most effectively conducted using a CMG with an output torque of 2-100 ft.-lbs.; however, the smallest CMG currently… more
Abstract:This Phase I project is for the development of a concept that integrates a printed circuit board with a high stiffness, high thermal conductivity composite material structure to achieve a multifunctional structural electronics packaging product for spacecraft application. The project involves… more
Abstract:Under the current U.S. Navy budget constrained environment it is desirable to get added functional performance from existing sonar systems. One such case is the need to provide instantaneous bearing ambiguity resolution for threat torpedoes at tactically significant ranges via U.S. Navy Surface… more
Abstract:When waveguides of high power radar systems are installed in corrosive environments gaps tend to form at the joints. These gaps change the characteristic impedance of the waveguide, causing reduced system efficiency and potential damage to the radar. An indication of these gaps are arcs generated… more
Abstract:Pulsed power technology, which calls upon the rapid discharge of capacitively stored electrical energy, can replace explosives in many applications. Mining metal forming, and echo ranging are examples. This proposal is for the design of a pulsed power sonobuoy suitable for use in a three-element… more
Abstract:MODELING ANBD SIMULATIONS ARE USED EXTENSIVELY IN THE DESIGN AND ANALYSIS OF "BULK" EXPLOSIVES DETECTION DEVICES. HOWEVER, OVERSIMPLIFICATION OF THE INPUT MODEL, NAMELY LUGGAGE AND EXPLOSIVE CONTENTS, CAN LEAD TO POOR DETECTOR DESIGNS. MANUAL PRODUCTION OF SUCH INPUT IS COSTLY AND ERROR PRONE. THIS… more
Abstract:This proposal discusses the development of a Graphical Vulnerability Assessment (GVA) system for setting up, executing, and visualizing the results of vulnerability assessments. The vulnerability assessments might be for hardened concrete targets, mobile ground targets, or mobile air targets. This… more
Abstract:A new automated methodology for collecting, analyzing, and reporting fragment data from warhead arena tests is proposed. While the Air Force has digitally recorded average fragment velocity data using electronic velocity screens since 1971, fragment mass distributions are still determined using a… more
Abstract:Under the proposed research a single degree-of-freedom hinge will be developed that exaggerates actuation by either a piezoceramic or a shape-memory alloy. The proposed hinge is a marriage of two concepts, one providing exaggerated excitation and the other providing bearing-free rotational mobility… more
Abstract:ARA along with its team member Ryan International Airlines proposes to develop an innovative stochastic decision tool for selecting among the various life extensions options for aging aircraft. The methodology is based on a genetic algorithm search that can efficiently choose among various… more
Abstract:The long range objective is to develop a radio frequency (RF) antenna array for optimized magnetic resonance imaging (MRI) of the human breast. Recent MRI technique development has made possible sensitive detection of breast cancer and other abnormalities, but the major manufacturers of MRI systems… more
Abstract:In order to produce shelters that more effectively shield military communications and electronic equipment from electromagnetic radiation, improvements must be made in manufacturing technology for graphite fiber composite materials. Of particular importance is the development of composite… 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.
