Abstract:At a time when the Navy is actively moving more training from shore to shipboard, it is critical that quantitative tools and measurements be developed and used to ensure that Navy training is meeting established objectives. The Navy wants to know that this movement away from more costly shore-based… more
Abstract:The lithium/thionyl chloride bipolar battery configuration, with thin electrode and separator components, is ideal for high rate voltage and high power applications. The bipolar electrode design supports a high rate capability by providing shortest and least resistive current path between adjacent… more
Abstract:Lithium-ion rechargeable battery technology has been developed and commercialized by several Japanese organizations. Small cylindrical cells are now available in the United States through Japanese manufacturers for laptop computer, cellular telephone and camcorder applications. Lithium-ion cells… more
Abstract:The electrical energy storage devices of hybrid elctric vehicles must be capable of being repeatedly and rapidly charged and discharged at widely varying rates while providing a high energy density/specific energy at high operating efficiencies. As a result, it appears likely that a combination of… more
Abstract:As the ability to communicate with the health care system becomes more important, there isa risk that minority populations, particularly non-English speaking and undeserved persons, will fallfurther behind in the level of care they receive. We are currently developing a general healthcare planfor… 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:Expendable mine-hunting countermeasures require a propulsion system that is acoustically and magnetically quiet while being light in weight, reliable, and inexpensive. Proposed for development and demonstration is a composite spring energy storage device. Calculations show that a spring weighing… more
Abstract:Passive detection and classification of missiles, aircraft, and units with internal combustion engines and rocket motors beyond the visual horizon is a capability of substantial tactical significance. Electromagnetic radiation from ions in engines has been identified as a potentially exploitable… more
Abstract:Approaches to Distributed Interactive Simulation (DIS) as they stand today cannot support the Navy's need for shore-based or deployed mission rehearsal. An advanced intelligent interface to extend the DIS Semi-Automated Forces (SAF) model is proposed that will be capable of supporting networked,… more
Abstract:PRESENT TRAIN DETECTION SCHEMES RELY LARGELY ON A LOW RESISTANCE THROUGH THE TRAIN'S WHEELS TO PERTURBATE A STABLE ELECTRICAL CIRCUIT. WHILE ELEGANT IN PRINCIPLE, THE DESIGN IS PLAGUED BY OXIDE FILMS AND MATERIAL BUILDUP ON THE RAIL, SNEAK PATHS THROUGH THE BALLAST AND OTHER UNCONTROLLABLE VARIABLES… more
Abstract:Marine Acoustics. Inc. (MAI), proposes applying existing passive acoustic localization technology originally developed for marine mammal tracking to submarine sonar applications. The commercial scientific processor technology developed by MAI will be adapted for integration into a submarine combat… more
Abstract:We are proposing to develop a novel compact blue fiber laser which overcomes the limitations of currently available lasers. These lasers offer significant advantages over the solid-state and gas lasers that are presently available. Fiber lasers are compact, efficient, widely tunable, and deliver… more
Abstract:Metal Injection Molding (MIM) partsmakers have indicated that the use of alloy metal powders currently available results in unacceptable distortion of large aspect ratio parts. This is attributed to the low "brown" strength of debound parts made with spherical gas atomized powder. This proposal… more
Abstract:The addition of Sic Platelets to selected diboride material systems offers the possibilities of increased toughness and improved Thermal protection. The innovative use of single crystal silicon carbide platelets with their highly reflective crystalographic planes, could lead to increased hot wall… 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.
