The instrument (developed by the PI, who is a New Investigator) will be… more
Abstract:DESCRIPTION (provided by applicant): Contrast-enhanced MRI has been proven to be a very sensitive modality for the early diagnosis of breast cancer in young women and/or in women with radiographically-dense breasts. The American Cancer Society recommends that high-risk women with lifetime risk… more
Abstract:This Small Business Innovation Research (SBIR) Phase I project relies on a novel and surprising physiological phenomenon recently published by the company and its academic collaborators: That magnetic gradient fields used in MRI can be dramatically increased without causing unpleasant nerve… more
Abstract:ABSTRACT: Welkin Sciences proposes to design and build a Wideband Digital Channelizer for SATCOM (WDCS) to address the Air Force"s needs to reduce size, weight and power (SWaP) of future SATCOM terminal equipment. Our proposed solution for the WDCS will facilitate the introduction of… more
Abstract:Welkin Sciences proposes to develop two run-time channel realization generators that are functionally equivalent to DTRAs ACIRF code. One is a software only implementation suitable for computer link simulations and test analysis applications. The other is a combination of software and FPGA-based… more
Abstract:Successful nuclear test-ban treaty monitoring requires advanced data processing to detect, locate and accurately characterize seismic signals as explosions or earthquakes. In recent years the ability to monitor small events that may be seen only at local distances has become increasingly important.… more
Abstract:ABSTRACT: The Air Force"s High Velocity Maintenance (HVM) initiative aims to better emulate industry"s high daily rate of touch-labor maintenance and rapid return-to-service. One barrier to HVM is scheduling of the maintenance. Currently, once an aircraft arrives at the depot, it spends… more
Abstract:Wireless Sensor Technologies has for several years been developing a passive Wireless Temperature Sensor (WTS) for gas turbine engine and other harsh environment applications under the under sponsorship of the Air Force (Non-destructive Test Program) and the Navy (SBIR Topic N08-004). Once… more
Abstract:Wolf Technical Services, Inc. (Wolf) is developing a Modular Anthropomorphic Test Device (ATD) that is specifically designed for use in blast and ballistic testing. The ATD offers improved biofidelity compared to existing ATDs, with a frangible skeletal system and soft-tissue covering that simulates… 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.
