Abstract:Ingested particulates, especially sand, severely degrade performance and increase wear in small gas turbine engines used in helicopter auxiliary and secodary power units. Existig Inlet Particle Separator (IPS) systems based on Bortex tube designs have two major limitations: their efficiency… more
Abstract:The project objectives are to develop and evaluate a generic methodology foremission control of a wide variety of air toxic particulate using a revolutionarybreakthrough in filtration technology based on the recently developed BoundaryLayer Momentum Transfer (BLTM) concept. This novel filter is… more
Abstract:The proposed Pulse Power Thyristor (PPT) could replace spark gaps, vacuum switches, thyratrons and ignitrons at operating temperatures over 200Â¿ C. The Pulse Power Opening Switch Thyristor (the PPOST), a variation of the PPT, could also exceed the performance of MCT's, IGBT's and GTO's with… more
Abstract:THIS PROJECT WILL DEVELOP A NOVEL CERAMIC MATERIAL, MADE OF A CERIA-ZIRCONIA (CEO2-ZRO2) THOUGHENED ALUMINA (AL1O3), WHICH IS EXPECTED TO EXHIBIT SUPERIOR STRENGTH AND CORROSION (ALKALI, SULPHATE) AND EROSION RESISTANCE IN HIGH TEMPERATURE ENVIRONMENTS, SUCH AS COAL-DERIVED HOT GASES. THIS MATERIAL… more
Abstract:Prior IR&D work by Spectro Dynamic Systems (SDS) and others demonstrated that silver coated cenospheres (SCC) 1) provide a unique pigment for achieving low emissivity coatings, and 2) can be modified to achieve microwave compatibility with little or no loss of low emissivity properties. This… more
Abstract:We will develop, test, and disseminate a high school alcohol abuse prevention program. The programstudents identified as peer opinion leaders as members of a Student Improvement Team. Team members wand trained to complete three tasks. First, they will actively identify and comment fellow… more
Abstract:US Army missions require a safe, long-cycle-life lithium battery that is rechargeable, efficient and reliable for powering electronics for future soldier sytsems applications. A solid polymer electrolyte for lithium batteries will allow placement of the electrodes in close proximity, bipolar cell… more
Abstract:ADDITION TO THE HAND HELD COMPUTER, THE DIACARE PROGRAM WILLALSO INCLUDE A MICROCOMPUTER BASED PHYSICIAN BASE STATION. THIS SYSTEM WILL ALLOW THE PHYSICIAN TO DOWNLOAD DATA FROM THE HAND HELD COMPUTER AS WELL AS CHANGE PRESCRIPTIONS FOR DIET AND INSULIN. WITH THE ADDITION OF A MODEM SYSTEM THIS… more
Abstract:This Phase I effort will investigate the feasibility of using microencapsulated phase change materials (microPCMs) together with diamond film heat spreaders to address the special heat-removal needs of high-power microelectronic packages. Previous research at Triangle Research and Development… more
Abstract:Oil mists from machining operations have long been associated with occupational disease inexposed workers. Concern has increased with recent evidence that exposure to these mists is associatedwith throat, pancreas, rectum, and prostate cancers as well as breathing problems and respiratoryillnesses.… 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.
