Abstract:Detecting light at the single photon level is a fundamental measurement function that is useful in a wide variety of applications, including such diverse fields as quantum communications, laser ranging, and biological spectroscopy. Avalanche photodiode based single-photon detectors are convenient… more
Abstract:U.S. intelligence, reconnaissance, and surveillance (ISR) platforms employ SIGINT sensors for target platform detection, identification and location. Many receivers are narrowband and are scanned over the RF spectrum (e.g., 2-18 GHz) in search of RF emitters of interest. With the rapid proliferation… more
Abstract:Nonlinear manifold learning is an active area of mathematical research. Unfortunately, the extant literature has far less to offer on the problem of interactive nonlinear manifold learning. In other words, satisfactory nonlinear manifold learning approaches that put the''human in the… more
Abstract:A goal of Uncertainty Quantification (UQ) is to use computer simulation of complex systems to make scientifically informed assessments for high-consequence decisions. Because end-to-end empirical data is difficult to obtain for the Ballistic Missile Defense System (BMDS), computer simulation… more
Abstract:The US Navy uses manned and unmanned airborne platforms for ISR missions in challenging littoral environments with non-segregated airspace, restricted operating regions, and sensor occlusions, while tracking and classifying potentially hundreds of targets. In this Phase I effort, we propose to… more
Abstract:Department of Defense (DoD) operations are supported by a global network of computers, sensors, and equipment that is continually at risk of being breached by adversaries. Despite heavy investments in security and cyber defense, the ubiquity and interconnectedness of DoD equipment leave open the… more
Abstract:For Unmanned Aircraft Systems (UAS) to operate seamlessly in both the U.S. National Airspace System (NAS) and abroad, it will be crucial that they possess a sense-and-avoid (SAA) capability that can ensure safe operations among maneuvering, non-cooperative aircraft. Numerica Corporation, in… more
Abstract:Emerging infrared (IR) sensor assets will play a crucial role in creating a robust and flexible Ballistic Missile Defense System (BMDS) because they are more easily deployed in forward-based and/or space-based environments, providing coverage of threats beyond the range of terrestrial sensors, and… more
Abstract:This Small Business Innovation Research Program (SBIR) Phase I project will develop algorithms and prototype software to track and quantify forces experienced by single-biomolecules in living cells. The approach is built on recent advances in time series analysis to: (1) fit 2-D/3-D stochastic… more
Abstract:ABSTRACT: Current and projected limitations on the maximum power from a high power single mode fiber laser amplifier impose architectural limitations on a high power phased array laser weapon system. Prior studies strongly indicate that when faced with this limitation the optimal approach is (to… 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.
