The main objective from Phase I… more
Abstract:A technique that enables rapid high fidelity SAR scene generation is proposed. Results of Phase I have shown the proposed technique superior to current convolution methods. The technique will be optimized and tested for the AMRDEC common scene generator. A stand-alone product for commercialization… more
Abstract:An increasing requirement for today"s military personnel is to perform multiple tasks at high functional levels despite elevated risks and reduced manning resulting in consistent, solid decision making. In response to this need, SimVentions proposes to develop measurable and validated… more
Abstract:One of the key challenges for Navy acquisition personnel (sponsors and program managers) is to track capabilities from the Research and Development (R & D) stage to deployment of a capability into the fleet to ensure the Navy is meeting current and future threats while filling the gaps in… more
Abstract:In an attempt to maximize software re-use and to lower overall development and life cycle combat system maintenance cost, the Navy is moving toward open architecture and a product line approach to building software for tactical systems. The concept of open architecture is to keep application… more
Abstract:One of the most significant issues facing amputees leaving rehabilitation units is the loss of connectivity with peers and caregivers. The new Amputee Virtual Environment Support Space (AVESS) being constructed within Second Life is a great resource enabling social networking between returning… more
Abstract:DESCRIPTION (provided by applicant): There is a need for highly specific, ultra-sensitive, low volume assays for cardiac troponin (cTnI), fast-twitch skeletal troponin-I (fsTnI) and slow-twitch skeletal troponin-I (ssTnI)in rats to assess and differentiatebetween cardiac and muscle toxicity in… more
Abstract:Diamond crystals with small total thickness variation (TTV) and local thickness variation (LTV) values are needed for position sensitive fast particle detectors for particle tracking/timing, and detecting direct/indirect beams. The fabrication of ultra-flat, low surface defectivity diamond detectors… more
Abstract:Solid state lighting is being promoted as the ultimate lamps of future. Though the internal quantum efficiency of OLED devices is almost 100%, external efficiency is a mere 36% mainly because of poor light out-coupling (~40%) from the device. Improvement in light out-coupling to & gt;70% and… more
Abstract:The fabrication of high-quality ultra thin (~20 micron) diamond crystals targets for 9 GeV highly polarized photon beams is an outstanding challenge. Current state of the art polishing/thinning techniques are not successful in thinning single crystal diamond to such dimension because of its extreme… more
Abstract:As the epi quality of HgCdTe layers is dependent on the quality of silicon surfaces, it is imperative that the (112) Si surfaces be pristine and devoid of defects. Unfortunately, the commercial available (112) Si surfaces are typically poor quality due to the presence of large number of COP (crystal… more
Abstract:This Small Business Innovation Research (SBIR) Phase II project will develop the next generation of lightweight materials by utilizing recycled thermoplastic composites to achieve energy efficiency and impact protection for transportation and residential and commercial building applications.… more
Abstract:We have developed a low dropout (LDO) regulator using a patented MESFET transistor technology that can be manufactured in commercial CMOS foundries with no changes to the process flow. The regulator is stable under all load conditions without an external compensation capacitor, thereby reducing the… more
Abstract:We have developed a novel metal-semiconductor field-effect-transistor (MESFET) technology suitable for extreme environment electronics. The MESFET technology is fully CMOS-compatible and can be integrated alongside conventional MOSFETs with no changes to the process flow. Unlike the MOSFETs however,… more
Abstract:US oil shale reserves contain a vast carbon energy source which if produced in an economically feasible and environmentally safe manner - would provide part of the solution for future US energy needs. While no commercial production of oil shales currently occurs, in situ retorting is generally… more
Abstract:The ability to effectively use large amount of automatically collected geophysical and hydrological data is relevant for both operational (clean up related) and scientific Department of Energy needs. Currently, data from geophysical monitoring systems at DOE sites requires extensive manual data… more
Abstract:"The ability to determine air pollutant emission quantity and emission rate are extremely important for environmental protection, policy making, and law enforcement. A pollutant emission rate can be determined by calculating the product of the airflow rate from an exhaust fan and the composition of… more
Abstract:Due to the possible transmission of blood-borne diseases, biting insects, mosquitoes, midges, and sand flies pose increasing danger to deployed military personnel and humans in locations around the globe. The SkySight Technologies approach to creating and demonstrating a tent trap to capture biting… more
Abstract:The ocean bottom is a protective location for sensors, unless a trawl fishing rig drags over the sensor. Because a trawl fishing rig scrapes the ocean floor and scoops fish into a net, it can be devastating to bottom mounted sensors, especially when sensors are vertically tethered in the water… 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.
