Abstract:This SBIR program is aimed at improving the power density of rechargeable cells in general, and particularly those used in underwater vehicles. We intend to achieve that objective by advancing the state-of_the-art of bipolar electrodes, where both positive and negatives are built on a common current… more
Abstract:AN INNOVATIVE REGENERATOR USEABLE IN STIRLING, PULSE TUBE, GIFFORD-MCMAHON AND SIBLING CYCLE CRYOCOOLERS IS PROPOSED. IT WILL OFFER IMPROVED PERFORMANCE IN TERMS OF RELIABILITY, UNIFORMITY, COST AND EFFICIENCY. THE REGENERATOR WILL BE FABRICATED WITH AVAILABLE MATERIALS AND TECHNIQUES USED IN AN… more
Abstract:AGRICULTURAL ENGINEERS AND SCIENTISTS HAVE EXPRESSED A NEED FOR A TRULY PORTABLE FLOW MEASUREMENT SYSTEM THAT RELIES ON SIMPLE PHYSICAL PRINCIPLES. THE SYSTEM SHOULD INCLUDE INEXPENSIVE AND RELIABLE SENSORS CAPABLE OF INTERFACING WITH ELECTRONIC EQUIPMENT. THIS RESEARCH WILL INVESTIGATE THE… more
Abstract:As cancer treatments improve, the view that the illness is "chronic" rather than "terminal" isbecoming widespread. Under this new paradigm, caregivers have an increasing obligation to helppatients and their families learn how to live with the illness. While attention is given to "quality of life"as… more
Abstract:Many military installations and Department of Defense (DoD) contractors are subject to recently promulgated regulations that require storm water flow metering and collection of both grab samples (in response to a rainfall event of a specified intensity) and flow-weighted composite samples. Such… more
Abstract:A potentially low cost method of producing prepreg tow is proposed. The method for fabricating impregnated tow suitable for Automated Fiber Placement (AFP) technology, while defined, does not include a low cost methodology for producing high quality, dimensional accurate continuous product. This… more
Abstract:The proposed innovation is a two-actuator, singularity-free double pointing system which has a spherical geometry. It has potentially widespread application as the basis of a new generation of singularity-free manipulator wrists which will not generate coupled arm/wrist singularities. It will also… more
Abstract:THE ORTHODONTIC FORCES APPLIED TO THE DENTITION AND THE RESISTANCE THE PERIODONTICS OFFERS TO THESE FORCES CONTROL THE RESULTING TOOTH MOVEMENT. THE RATIONALE OF THIS RESEARCH IS TO PROVIDE THE ORTHODONTIST WITH THE CLINICAL INSTRUMENTATION WITH WHICH TO MEASURE THE FORCES AND COUPLES PRODUCED BY… more
Abstract:A NOVEL VISCOMETER DESIGN WHICH HAS THE CAPABILITY TO PROVIDE A DIRECT READING OF ON-SET OF CRITICAL SHEAR RATES AT WHICH HIGHLY FILLED MATERIALS START TO DECOMPOSE IS DISCUSSED. A DEVICE SIMILARY TO ONE PROPOSED IN THIS PROGRAM HAS ALREADY BEEN BUILT AND EFFECTIVELY USED AT OIL COMPANIES. THE… more
Abstract:MELTER-ISV SIMULATOR IS BEING DEVELOPED AS THE INDUSTRY-STANDARD COMPUTATIONAL MODEL FOR SIMULATING IN-SITU VITRIFICATION (ISV) PROCESSES THAT ARE CURRENTLY BEING CONSIDERED AS ALTERNATIVE REMEDIATION TECHNOLOGIES FOR HAZARDOUS-WASTE SITES. THE ADVANCED STATE-OF-THE-ART COMPUTATIONAL MODEL IS ABLE… more
Abstract:The title of the proposed Phase I project is "Megaprogramming for NASA's Unmanned Missions: Domain-Based Software Engineering". The objective of the Phase I activities is to develop a domain-based software engineering life cycle process consisting of an integrated, object-based domain-engineering… more
Abstract:Survival rates for medical trauma caused either in the military battlefield or at a civilian injury scene decrease dramatically if treatment is delayed for more than one hour. The ability to remotely sense and assess the severity of wounds would enhance support decisions to plan and manage overall… more
Abstract:POSITRON EMISSION TOMOGRAPHY (PET) IS A POWERFUL NEW TOOL FOR RADIOGRAPHIC IMAGING OF HUMAN ORGANS, PARTICULARLY THE BRAIN. HOWEVER, MOST PRESENTLY KNOWN SCINTILLATOR MATERIALS FIND THEIR APPLICATION LIMITED BY DEFICIENCIES IN ONE OR MORE OF THE DESIRED CHARACTERISTICS: BRIGHTNESS, STOPPING POWER,… more
Abstract:DETECTION OF WEAPONRY AND OTHER HAZARDS IS AN UNFORTUNATE BUT NECESSARY FACTOR IN MODERN TRANSPORTATION ENVIRONMENT. FOR INANIMATE OBJECTS, ONE PARTICULARLY ATTRACTIVE TECHNIQUE IS GAMMARAY DETECTION. IRRADIATION WITH A HIGH-ENERGY SOURCE, SUCH AS A NEUTRON EMITTER, CAUSES ELEMENTS IN THE OBJECT TO… more
Abstract:Since hybrid propulsion is being developed for space launch vehicles, there is a strong need for understanding the physical mechanisms causing hybrid rocket combustion instability. The project's objective is to develop and demonstrate a Liquid Oxygen Hybrid Motor Combustion Stability Test Bed. This… 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.
