Abstract:A need exists for a reasonable representation of the physical properties and interactions of weapons, soldiers and structures on urbanized terrain, including: A reasonable representation of buildings by class as describe in FM90-10, A characterization of the degree of protection afforded by each… more
Abstract:A quality simulation which allows a user to simulate the acoustic emissions in a multi-source environment and then study the effects these conditions have on a set of acoustic sensors would be of great value. As acoustic sensors technology continues to advance with robust algorithms for detection,… more
Abstract:Sonar transducer mounting hardware installed on current U.S. Navy submarines is constructed from metallic materials that have been found to have costly corrosion problems. Metallic transducer mounting brackets are heavy, are constructed from expensive corrosion resistant metals, use expensive… more
Abstract:The Naval Surface Fire support program is developing an upgrade to the Mk-45 gun which will require enhanced propellant charges to increase muzzle energy. The gun barrel needs to be lengthened from a 5"/54 to a 5"/70 caliber to allow sufficient in-bore volume for the complete combustion of the… more
Abstract:Navy fiber optic connectors use a heat cured adhesive to hold the fiber within the connector ferrule. A cure time of twenty minutes at 120Â¿ C is currently required. A fast curing (< 3 minutes), room temperature cure adhesive with physical properties that meet the current specification… more
Abstract:The photonics mast (PM) and integrated ESM mast outer sensor heads/housings planned for advanced submarine (NSSN) system applications will be exposed to demanding structural loads and severe environmental exposures. The PM housings must be able to withstand hydrostatic loads, hydrodynamic loads,… more
Abstract:40837 November 13, 1996
Crosswell Seismic Imaging holds great promise for imaging the region between existing oil wells to incrementally increase the recovery of the 368 billion barrels of oil still in the ground (of the 500 billion barrels… more
Abstract:40828 November 13, 1996
While seismic data are used to determine the presence and extent of underground oil and gas reservoirs, their interpretation is very difficult. For example, it is crucial to know whether features observed in the… more
Abstract:The proposed work will explore possibilities for a less than 100 Watt-hour, pocket-sized, Trymer-"Type", thermoelectric generator that converts high energy-density fuels into electrical power for small system usage. Computer models and an actual small-scale working generator will be developed in… more
Abstract:This innovation proposes the use of a thin film stratospheric balloon to lift a launch vehicle with a payload to an altitude above most of the Earth's atmosphere, then ignite the launch vehicle rocket motor. It will have the capability to carry the payload to its final destination, either into… more
Abstract:Routine, fully automated analysis of air, water, soils, sludge, etch., would help target clean-up efforts and improve worker safety in the field. The availability of highly portable and affordable chemical analyzers would allow widespread deployment, which has been unobtainable with traditional… more
Abstract:Each year in the United States over 600,000 tons of regulated biomedical waste are generated by hospitals, laboratories and clinics. Disposing of these wastes safely, economically and within environmental guidelines is a growing problem. The accepted methods of waste treatment, such as… more
Abstract:Each individual soldier is becoming increasingly dependent on electronics and this dependency requires greater amounts of electrical power. Before long these requirements will exceed the capabilities of batteries and a new system will be required. Proton exchange membrane (PEM) fuel cells have the… more
Abstract:Traditional parenternal vaccines have many limitations which pose problems for both military and civilian vaccination programs. Parenternal vaccines must be administered by trained medical personnel, booster doses are generally required to obtain maximum protection, they are usually only effective… more
Abstract:This Phase I project proposes an investigation involving molten salt systems as novel electrolytes for use in electrochemical machining (ECM). As the air-breathing propulsion materials (such as titanium and nickel aluminides) used in Navy aircraft jet engines are becoming harder and more brittle,… more
Abstract:The Department of Defense has undertaken an ambitious environmental restoration program at thousands of facilities in the U.S. Many of these facilities have been contaminated by the discharge of dissolved heavy metals. Often these contaminants migrate into the ground water where they pose a… more
Abstract:the objective of this proposal is to develop a low cost coating that provides increased corrosion resistance for application on automobile exhaust system components subjected to high temperatures as well as corrosive coastal environments. The methods available for developing corrosion resistant… 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.
