Abstract:This Phase I project has two primary objectives. The first objective is to develop an engineering model of Resonant Tunneling Devices (RTD) to be implemented in AIM-Spice, a commercial software package running under Windows 95/NT. The development of a reliable device model is a prerequisite for… more
Abstract:This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped… more
Abstract:We propose to develop Co-located Triple Band Quantum Well Infrared Photodetectors (QWIP) Arrays. The innovative features are: Co-located Triple Band Structure The detection of short waveband (0.7-2.micro.m) midwaveband (3-5.micro.m) and long waveband (8-13.micro.m) signals takes in the same pixel… more
Abstract:The proposed research combines an innovative eigenvector method with other electromagnetic techniques to produce a hybrid approach towards solving the EM coupling to satellite cavity problem. The physical structure is divided into an exterior region and one or more interior regions. The exterior… more
Abstract:SOCOM needs a new generation of high power density, multi-fuel, lig htweight, compact outboard engines of 30, 55, and 70 HP. Tactical use by special operations forces (SOF) requires they incorporate increased stealth capabilities, be submersible, be simple to set up and operate by one person of… more
Abstract:The proposed effort is to design a space-qualified dual-frequency GPS/GLONASS receiver with enhanced capabilities for atmospheric remote sounding. While such soundings have been performed using GPS-only receivers, a space-based GPS/GLONASS receiver would be superior in terms of coverage and… more
Abstract:A typical Air Force base will produce several thousand gallons per year of used turbine engine lubricants. These lubricants can be collected on site and sold at relatively low cost for other uses (e.g., plasticizer). The potential for contamination of the collected lubricants, particularly with… more
Abstract:The Air Force has requirements for site cleanup and environmental compliance related to contaminated groundwater. Remedial operations of water contaminated with volatile organic compounds (VOCs) presently utilize technologies such as air stripping, activated carbon treatment, reverse… more
Abstract:Additive technology has been developed which will extend the operating temperature of common aviation fuels like JP-5. However, the currently available additive packages cannot extend the operating temperature high enough to meet the anticipated requirements of future gas turbine engine designs… more
Abstract:The AF requires a portable instrument to measure thermal reflectance signatures from target surfaces. In the field, measurements include 1) total integrated scatter; 2) retro-reflected scatter; 3) angular scatter from normal incidense to 75 degrees off-normal; and 4) parallel and perpendicular… more
Abstract:SOI technology offers the potential for creating radiation hard integrated circuits which can operate at low power and high speed. These advances are important for DoD and space applications and for battery operated devices. SOI is excellent for rad-hard applications because dielectric isolation of… more
Abstract:Infrared spectroscopy has ong been recognized as an excellent tool for sending and monitoring chemical species and thermal signatures. There is a need for low-cost devices which can be used in these applications. Advanced Fuel Research Inc (AFR) is presently developing a micro-machined graded… more

Advanced Fuel Research, Inc.
Advanced thermal coating materials are being developed for use in the combustor section of high performance turbine engines. To optimize their use, accurate surface temperature measurements are required… more
Abstract:Major improvements in process control, compliance monitoring, and environmental decisionmaking could be made if more accurate, less costly, more rugged techniques were available for continuous monitoring of multiple gas phase pollutants. As part of the solution, Fourier Transform Infrared (FT-IR)… more
Abstract:The long range objective of this proposal is to find mild, highly specific conditions for the targeted addition of polyethylene glycol to specific residues of recombinant proteins. Because proteins which have been modified by polyethylene glycol addition have increased serum persistence and… more
Abstract:In Phase I, a head and neck array prototype RF coil capable of operating in the multiple (head only, neck only, head & neck) modes will be developed at l.5T. Phantom measurements and preliminary volunteer scans will be obtained to evaluate the signal-to-noise, uniformity, coverage, claustrophobia,… 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.
