Abstract:This research will explore: (1) real-time Data Base Management System (RT-DBMS) high-level query language, and (2) the primitive level language interface to RT-DBMS "engines." We will focus on interface features rather than implementation issues. The goal is to provide RT-DBMS technology for… more
Abstract:THE OBJECTIVE OF THE PROPOSED PROJECT IS TO DEVELOP AND DEMONSTRATE A LOW- COST ALTERNATIVE TO A MODIFIED CLAUS PLAN FOR CONVERSION OF SO2 TO ELEMENTAL SULFUR, AND, MORE SPECIFICALLY, TO OPTIMIZE AN EXISTING ACID RAIN SORBENT REGENERATION PROCESS DEVELOPED BY SANITECH TO YIELD DIRECTLY A PURE… more
Abstract:The immediate Spectra Group Ltd (SGL) contribution in responding to N93-045 is the capacity to produce rapid prototypes directly from CT scans using stereolithography. SGL has been printing medical models derived from CT scans for more than a year and has access to industrial CT scan devices… more
Abstract:The AN/MPS-36 radar is a missile range instrumentation radar used for precision tracking of flight vehicles. Angular resolution is achieved by a monopulse lobing technique. The AN/MPS-36 radars were built in the 1970'x and since their inception have been subject to occasional tracking problems… more
Abstract:Spectra Research, Inc. (S*R) proposes to develop and demonstrate a technique for detecting low power CW laser sources operating in the visible (0.4-1.1 m), near infrared (1.0-3.0 m), and far infrared (9.0-11.0 m) spectral bands and to formulate a design for a visible spectral band system for… more
Abstract:For this Phase I SBIR, Spectra Research, Inc. proposes to research rugged, non-intrusive IFF concepts which employ unique low cost discrimination techniques to detect and positively identify friendly combat soldiers. The proposed design operates on passive non-cooperative emissive radiation and… more
Abstract:Spectra Research Inc. (S*R) proposes to configure off-the-shelf specialized antennas for installation in the wall of an anechoic chamber to provide a quick look test capability where fine direction of arrival (DOA) is not required. Several technical approaches to the antenna installation will be… more
Abstract:The present method of detecting wideband pulsed and continuous wave (CW) electromagnetic fields utilizes asymptotic conical dipole devices. Because of the metallic nature of this device, the electromagnetic fields are perturbed and lead to inaccurate measurements. In addition, since this is a D-dot… more
Abstract:FIELD MEDICAL USE OF MANY SURGICAL INSTRUMENTS, INCLUDING DELICATE INSTRUMENTS SUCH AS ENDOSCOPES, REQUIRES COLD STERILIZATION, COLD BEING DEFINED AS A TEMPERATURE TANGE BETWEEN AMBIENT (25C) AND MODERATELY ELEVATED (UP TO 60C). BECAUSE OF HAZARDS IN TRANSPORTING AND USING ETHYLENE OXIDE, IT HAS… more
Abstract:The objective of this project is to examine the feasibility of developing a long-term planning concept for determining the utility of incorporating non-defense related mission equipment into future Air Force weapon systems. This project will concentrate on the addition of equipment necessary to… more
Abstract:SUNPOWER PROPOSES TO DESIGN MICROSTRUCTURES FOR HEAT TRANSFER IN NOVEL STIRLING MICROREFRIGERATORS INSIDE MULTI-CHIP MODULE PACKAGES FOR REMOVING HEAT AT LOW TEMPERATURES FROM WAFER SCALE INTEGRATED CIRCUITS IN SPACE SYSTEMS. THE MICROREFRIGERATOR EXPLOITS THE MATERIAL PROPERTIES, MECHANICAL DESIGNS… more
Abstract:Sunpower, Inc., proposes to demonstrate an electrically-driven free-piston Stirling refrigerator for Combat Medical Units. This silent, energy-efficient, highly reliable refrigerator will provide required cooler and freezer compartment temperatures without using a traditional compressor or CFCs. The… more
Abstract:SYSTRAN proposes to formulate (in Phase I) the top-level design of a Meta System application to support users of the Avionics Wind Tunnel (AWT). The AWT is a vision, shared by members of the Avionics Directorate, Flight Dynamics Directorate, and other Wright Laboratory and Area-B facilities, for a… more
Abstract:The thrust of the proposed research is to research and develop a 2-D joint measurement scheme for simultaneously measuring the droplet and gas velocities to enhance the understanding of the droplet-turbulence interactions. A Particle Image Velocimeter (PIV) for measuring the droplet velocity will be… more
Abstract:SPUTTERED COATINGS OF SOLID LUBRICATING DICHALCOGENIDES SUCHAS MOLYBOLENUM DISUFIDE HAVE RECEIVED CONSIDERABLE ATTENTION, PARTICULARLY DUE TO VACUUM AND SPACE APPLICATIONS. CONVENTIONAL MAGNETRON SPUTTERED FILMS OF THESE MATERIALS ON MOST SURFACES HAVE SHORT SLIDING LIFE. ASIGNIFICANT ENHANCEMENT OF… more
Abstract:THE PROPOSED RESEARCH ATTEMPTS TO DEVELOP AN ADVANCED CAPACITOR USING SiC FOR HIGH TEMPERATURE (400 0C), HIGH POWER, AND HIGH DENSITY ELECTRONIC COMPONENTS FOR AIRCRAFT OR AEROSPACE APPLICATION. THE CONVENTIONAL CAPACITOR CONSISTS OF A LARGE NUMBER OF METALLIZED POLYSULFONE FILM CAPACITORS IN… 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.
