MICROPROCESSOR CONTROLLED ELECTRIC FUEL INJECTION. 2. HIGH DURABILITY VALVED AND VALVELESS INLET DESIGNS. 3. OXYGENATED… more
Abstract:M-Dot, Inc. ("M-DOT") proposes to design, fabricate and test a thrust reverser system for low cost expendable turbojet engines. The system will be designed for application on the Sunstrand TJ-90 engine and will be configured for application on a bifurcated exhaust duct. The system will consist of… more
Abstract:The ability to increase bone formation in vitro and in vivo would lead to exciting and far reaching applications in the fields of orthopaedics and metabolic bone disease. Bone is a unique mechanosensitive tissue which, upon mechanical load, induces bioelectric potentials which regulate cellular… more
Abstract:Over 200,000 new cases of spinal cord and peripheral nerve injury occur in the United States every year. Methods for enhancing the repair of these injuries are currently sough. Pulsed electromagnetic fields (PEMFs) have been shown to enhance regeneration of central nervous system (CNS) and… more
Abstract:This project develops a generic software modification and menu-based authoring technology to enable people with developmental disabilities to use computers and to enable teachers, parents, and other professionals to create software fitted to specific uses, settings, and individuals. This responds… more
Abstract:This project applies multimedia computer technologies with the first full speech feedback capability on graphics-based computers (Windows 3.1 and Apple Macintosh) to computer software for persons with age-related cognitive disabilities such as memory problems. Applications include the development of… more
Abstract:"ONE OF THE MAJOR CONTRIBUTIONS OF ELECTROENCEPHALOGRAPHY HAS BEEN ITS APPLICATION IN THE DIAGNOSIS AND CLINICAL EVALUATION OF EPILEPSY". (KTONAS, 1987) HOWEVER, DESCRIPTIONS OF THE RULES USED DURING THE VISUAL INSPECTION OF THE ELECTROENCEPHALOGRAPHY (EEG) DATA ARE OFTEN SUBJECTIVE AND CAN VARY… more
Abstract:THE OBJECTIVES OF THIS RESEARCH PROJECT ARE TO DEVELOP AND TEST ULTRASONIC THERMOMETERS WITH NON-METAL SENSING ELEMENTS FOR TEMPERATURE MEASUREMENT AND CONTROL IN HIGHLY CORROSIVE MANUFACTURING ENVIRONMENTS. CANDIDATE NON-METAL MATERIALS FOR THE SENSING ELEMENT INCLUDE SAPPHIRE, ZIRCONIUM OXIDE,… more
Abstract:SPACE SHUTTLE FLIGHTS HAVE DEMONSTRATED THE VALUE OF FLEXIBLE CERAMIC BLANKETS SUCH AS ADVANCED FLEXIBLE REUSABLE SURFACE INSULATION (AFRS) FOR REENTRY THERMAL PROTECTION ON AREAS EXPOSED TO MODERATE HEATING RATES. OTHER CERAMIC BLANKETS ARE BEING DEVELOPED FOR FUTURE SPACECRAFT SUCH AS THE NASP,… more
Abstract:A new method is proposed for the development of stable, high speed electro-optic polymers for optical waveguide devices such as switches and couplers. Thin polymer films will be produced by a new process that we refer to as flash evaporation. The process is based on negative electron beam… more
Abstract:ADDRESSING THE NEED FOR HIGHER RELIABILITY PULSE CAPACITORS TO SERVE DEMANDING APPLICATONS SUCHAS THE COPPER LASER INVERTER, A METALLIZED CAPACITOR IS PLANNED WITH A RATING OF 1-2 MICROFARADS (UF)/2000V, THAT HAS SUPERIOR DV-DT AND HIGH FREQUENCY CURRENT CARRYING CHARACTERISTICS, AND PROLONGED LIFE… more
Abstract:WE PROPOSE TO DEVELOP AN EXPERT GUIDED APPROACH TO CONSTRUCTING HIGH LEVEL MODELS USING DETAILED MODELS OF ARMY COMMUNICATIONS SYSTEMS IN THE CECOM INVENTORY AS THE GROUND LEVEL BASIS. SPECIFIC OBJECTIVES INCLUDE: TO IDENTIFY CHARACTERISTICS OF THE CECOM MODEL INVENTORY RE- LEVANT TO SUCH MODEL… more
Abstract:ADVANCED COMPOSITE MATERIALS HAVE EVOLVED TO BE THE CLASS OF MATERIALS WHICH MEET THE STRICT REQUIREMENTS OF MANY GROUND- AND SPACE-BASED CRITICAL STRUCTURES. SYSTEMS WHICH INCORPORATE THESE NOVEL MATERIALS ARE FREQUENTLY EXPOSED TO HARSH ENVIRMENTS DURING SERVICE, AND MUST THEREFORE BE MANUFACTURED… more
Abstract:The overall objective of this project is to develop a reliable, low-cost neural network architecture for sensors, and real-time processing to continuously monitor the structural health of the thick composite structure used in armored vehicles. The Phase I demonstration will be implemented with… more
Abstract:The development effort will be divided into two major tasks: develop and evaluate candidate protection concepts, and investigate and evaluate armor materials to be used in the concepts. There are unique ballistic protection concepts and armor materials which we will evaluate. We intend to consider,… 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.
