Abstract:THIS PROJECT WILL DEVELOP AN IMPROVED PROCESS FOR EPOXIDIZING UNSATURATED NATURAL OILS FOR A VARIETY OF APPLICATIONS. EPOXIDIZED SOYBEAN AND OTHER UNSATURATE NATURAL OILS ARE IMPORTANT SPECIALTY CHEMICAL PRODUCTS AND ARE EXAMPLES OF VALUE-ADDED APPLICATIONS OF AGRICULTURAL MATERIALS. CURRENT PROCESS… more
Abstract:Ground-penetrating radar is a new non-destructive tool for pavement evaluation. Pulse Radar, Inc., a U.S. company, headquartered in Houston, Texas, proposes to construct a unique air-coupled dual antenna system for both shallow and deep ground penetration. Shallow penetration will measure thickness… more
Abstract:In the proposed research, we will investigate a new class of long wavelength-IR (8-12 um) lasers which was first suggested by the PI in 1994. These lasers are based on cascaded type-II quantum wells. They maintain the electron recycling advantage of the recently reported quantum cascade laser, while… more
Abstract:We propose to develop high-temperature mid-infixed. (3-5 gm) laser diodes with a high repetition frequency > 50 KHz in pulsed mode or high output power in cw mode. Recently, we have demonstrated optically pumped 285 K IIIN Type-H Quanturn-Well lasers at 4.1 Jim with the maximum peak output power of… more
Abstract:Conventional optoelectronic packaging technologies failed to provide low-loss coupling among various optoelectronic devices that are pivotal for BMDO-mission-related tasks. To bridge different effective apertures of various optoelectronic devices are the major bottleneck needs to be overcome.… more
Abstract:Conventional electro-optic (EO) switches must have multiple electrode sections to ensure a producible polarization-insensitive device, which is impractical for high-speed operation and compact device integration. There have been great advances in achieving high-frequency operation using phase… more
Abstract:Conventional electrooptic materials failed to provide a polarization-insensitive switch unless an exotic electrode structure is employed. Such a drawback prohibits system insertion of electrooptic devices into an array of optical interconnection network. Radiant Research, Inc., proposes a novel… more
Abstract:To meet dependability requirements dictated by current trends in both defense and commercial technologies, massive modular redundancy and application specific designs will have to give way to more efficient, scalable and cost-effective approaches. This Phase I proposal introduces a method which… more
Abstract:The thrust of the proposed research is to develop a comprehensive and cost effective automated test insertion tool for boards and systems designed using Commercial Off-The Shelf (COTS) devices. The research will investigate promising test methodologies for testing non BIST devices in the… more
Abstract:The Critical-Time/Real-Time Database Management System is a Tandem Memory (Smart-Memory) which shares two memory functions. The memory functions are a Real-Time Data Memory (RDM) with separate I/O and a similar memory for storing of Distributed Data words (DDM) or parameters. Associated with each… more
Abstract:Systems & Processes Engineering Corp. (SPEC) proposed the development of a GaAs Field Programmable Gate Array (FPGA) for spaceborne applications. Digital Gate Array ICs combine functions of many logic gates into a single chip to improve speed, weight, and power dissipation. Field programmable gate… more
Abstract:Systems & Processes Engineering Corporation (SPEC) proposes to develop a Multi-Input Encoded/Decoder Application Specific Integrated Circuit (ASIC) chipset to be a programmable, universal interface between test equipment and digital recorders. The ASIC chepset will be fabricated using advanced GaAs… more
Abstract:Silicon and gallium arsenide cannot meet some of the power, frequency, temperature and speed requirements of the next generation of electronic devices. Therefore, alternative semiconductor materials for electronic devices must be developed. Silicon carbide has many required properties such as wide… 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.
