Abstract:The current generation of hybrid particle detectors at the International Linear Collider (ILC) falls well short of meeting the mass and resolution requirements: mass less than 0.1 radiation length/layer, resolution speed in the range of
Abstract:The many different generations of integrated circuit (IC) technologies required for new space exploration systems demand designs operate at multiple and often incompatible voltages. Extended utilization of current and development of new space exploration systems require multiple voltage levels be… more
Abstract:DESCRIPTION (provided by applicant): We will develop and evaluate a tool designed to support the collection of rich data for performing a Functional Behavior Assessment (FBA) in schools to support the development of intervention plans for children with special needs, specifically children with… more
Abstract:A simple clamping U bracket to secure itself under pressure on both sides of the aircraft's structural frame ribs. A clamp will be placed on every section where the bonded studs currently exist. A cavity on the bottom of each clamp will hold a stud or other tool to secure the blankets. The outer… more
Abstract:Manning Applied Technology proposes development of the MP-100 handheld FT-infrared photoacoustic chemical agent detector, following a highly successful Phase I effort. Chemical attacks and accidents can be mitigated partially by cost-effective sensors. High priority programs will benefit from a… more
Abstract:This project, titled Â¿Digitizing the K-8 Portion of the Positive Action Program for Web-Based Delivery,Â¿ is in response to Priority Two (Products) of the U.S. Department of Education Small Business Innovation Research Program, RFP Number: errd080008. The anticipated start date of this… more
Abstract:DESCRIPTION (provided by applicant): The Positive Action (PA) program is designed for substance abuse and violence prevention, and improves teaching skills, school leadership/administration skills, school organization, and both student behavior and academic achievement. Despite having strong… more
Abstract:The F-35 prognostic health management (PHM) system will generate a large volume of data on current and predicted component health. Tools are needed to automatically assimilate and analyze this data, and present findings and recommended actions to the user. These automated reasoner tools are… more
Abstract:The military is actively implementing diagnostics, prognostics, and health management technologies across platforms in an effort to reduce maintenance costs, increase readiness and availability, and improve safety. In aircraft electric power systems, the largest maintenance driver is the generator,… more
Abstract:Diagnostic and prognostic algorithms for many aircraft subsystems are steadily maturing. Unfortunately there is little experience integrating these technologies into a complete and practical on-board prognosis system, and integration often proceeds in an ad-hoc manner. Sentient Corporation proposes… more
Abstract:Although prognostic health monitoring systems for the mechanical aspects of the LAV-25 are currently under development, a comparable system for diagnosis of the electrical and weapons systems does not exist. System diagnosis is an expertise-based craft that is easily lost when turnover rates (due… more
Abstract:A great deal of effort has been put into health management of turbine engine turbomachinery components, such as bearings, disks and blades, while engine externals have received less research attention. Accessories on gas turbine engines include electrical, hydraulic, lubrication, and fuel subsystems… more
Abstract:Obtaining reliable diagnostic information on turbine engine main shaft bearings is difficult due to space constraints, operating environment, and poor transmissibility of vibration from the bearing to a case-mounted accelerometer. Prior work has shown that bearing cage parameters provide valuable… more
Abstract:The Air Force Research Laboratory (AFRL), Military Satellite Communication (MILSATCOM), and National Aeronautics and Space Administration (NASA) have a current and future need for advanced commercially available inherently radhard primitive cell libraries to support new designs for satellites and… more
Abstract:Various technologies available to space system designers that operate at different voltage levels. It is, however, important to interface, maintain, and update these systems. For example, the Sun Earth Connection (SEC) missions are likely to have a variety of experiments needing to be accomplished… more

Abstract:Manning Applied Technology proposes to develop a handheld infrared spectrometer, ideally suited to detection of airborne chemical agents at and below permissible exposure limits. This approach offers unmatched sensitivity and specificity for detection of all types of chemical vapors. The… more
Abstract:DESCRIPTION (provided by applicant): The sequencing of genomes has generated a huge amount of data still to be annotated. Computational methods are available to detect putative transcriptional promoter regions, but they are not 100% efficient and must be confirmed by experimentation. Unfortunately… 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.
