Abstract:The United States Air Force (USAF) operates one of the world"s largest fleets with an average age approaching 26 years. As the USAF transport fleet continues to age, costs of inspections, structural repairs, and component replacements will continue increasing. Given this large number of… more
Abstract:Analysis methods are not available to predict the life of structures exposed to spectral loads containing large cycles of low amplitude loads. The challenge is developing a computational technique to predict damage accumulation in the ultra high cycle fatigue (UHCF) regime and then integrate that… more
Abstract:Advanced computational tools capable of predicting the effects of fatigue corrosion on new alloys are needed to design the aircraft fleet of the future. The corrosion process is complex involving a combination of factors including material chemistry, processing history, microstructure, and… more
Abstract:The proposed project will develop a structural analysis framework incorporating high performance composite design methodologies to predict the reliability of sandwich termination features. The sandwich core termination region offers many challenges to properly design and verify its structural… more
Abstract:DESCRIPTION (provided by applicant): Tympanic membrane perforations are commonly seen in otology practices and about 150,000 repair surgeries are performed each year in the United States. Current office-based procedures such as paper patch tympanoplasty are relatively ineffective or, like the… more
Abstract:DESCRIPTION (provided by applicant): Annually, 5 to 7 million Americans are treated for chronic wounds that arise from diabetes, lower extremity arterial disease, lower extremity venous disease and edema, and pressure ulcers, and traumatic injuries, including burns. There is a real need for new… more
Abstract:DESCRIPTION (provided by applicant): Germanium gamma-ray imaging detectors will improve the quality of in-vivo molecular-imaging applications. The objective of this program is the development of the Germanium Gamma Cameras (GGCs) as modular component detector heads suitable for convenient… more
Abstract:DESCRIPTION (provided by applicant): Stroke is the 3rd leading cause of death and the primary cause of severe, long term disability. Each year 795,000 Americans have a stroke and the annual costs to the economy are 57.9 billion. The vast majority of acute ischemic strokes are caused by a thrombus… more
Abstract:It is becoming increasingly apparent that we, as a nation, need to quickly develop smarter solutions to control the overall generation and distribution of electrical energy as power demand across the grid expands in response to the increasing population and the growing prospect of energy intensive… more
Abstract:DESCRIPTION (provided by applicant): Molecular interactions form the basis of healthy metabolism as well as the manifestation of disease, and comprise the very foundation of drug treatment. Tools available to study molecular interactions in their nascent environment and physiological concentrations… more
Abstract:Alcohol abuse and its related health effects are estimated to have an economic cost in the US that approaches $200 Billion per year. However, current tests for alcohol use/abuse are not reliable except when administered within several hours of intoxication. Moreover, current clinical tests for… more
Abstract:In response to the proposal solicitation of''Wideband Scalable Multi-channel Digital Receiver/Exciter (DREX)', this proposal presents a phase-I research plan committing to provide a set of study and experiment results, and conceptual design of a scalable coherence method. A new… more
Abstract:The software system, Sensor Atom Configuration Software (SACS), will use of knowledge management techniques through ontologies capturing knowledge about sensor atoms and 3D targets, advance algorithm design, and concept of operations to allow for flexible sensor system design and predict sensor… more
Abstract:This Small Business Innovation Research Phase I project will develop the technology needed for high performance scintillating optical fiber-based neutron detectors.

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.
