Abstract:IAI proposes the design of a Waveform Agile Telemetry Transmitter (WATT) which will support simultaneous dual-band S-C band operation (S-band , 2200-2400 MHz and C-band selectable between 4400-4950 MHz and 5091- 5250 MHz), to achieve the goals of this solicitation. Our proposed WATT architecture… more
Abstract:In the modern world, people and machines are faced with ever-increasing amounts of data. Oftentimes, large data sets can be greatly reduced by identifying elements that are salient, within the context of a particular mission or goal. For example, in a military patrol video, hours of empty scenery… more
Abstract:ABSTRACT: We propose a unifying framework for multi-scale multi-resolution inference, analysis, and design of complex socio-technological networks. Our key innovation is to combine graph-analytical methods with functional analysis through information-geometric optimization across time, space, and… more
Abstract:ABSTRACT: It is very challenging to secure applications in today's networked computer systems where applications inherently share various resources and information. In this proposal, we propose a novel approach called policy guided isolation and strategically shielded exposure, to protect… more
Abstract:The Global Information Grid (GIG) has access to massive amounts of data from a vast number of sensors and sources. Extracting information from this quantity of sensor data is a significant challenge. Sensor data is often large, which taxes limited-bandwidth GIG interconnections. Current approaches… more
Abstract:Chalcogenide glass fibers are extensively used for delivery of mid-infrared (2 to 5 micron) laser wavelengths. They are needed for development of next-generation directed infrared countermeasure (DIRCM) systems. These new systems will have a reduction of both weight and size allowing their… more
Abstract:Synthetic scenario-based training of Navy personnel in the use of Navy SIGINT/IO systems has helped to reduce training costs, and it has enabled the personnel to be trained in an environment that sufficiently approximates real-world situations that could not otherwise be accomplished within the… more
Abstract:ABSTRACT: Microscopy is a critical enabling technology for advancing our understanding of nature. Imaging nanoscale objects with light in the extreme ultraviolet (EUV) and soft x-ray regions of the spectrum has advantages over visible light for resolution, elemental specificity, and imaging… more
Abstract:We propose a novel robot navigation paradigm based on high-level visual landmarks, including structural landmarks and object-level landmarks. The system will use our novel multilayered-feature graph (MFG) to combine multiple, heterogeneous features (from points to planes to vanishing points)… more
Abstract:ABSTRACT: The objective of this project is to design and fabricate multi-signal in-situ ablation sensors based on an acoustic transducer system, thermal measurement system (i.e., either photonic technology or in-situ thermal sensors based on ultra small thermocouples), and fast inverse heat… more
Abstract:We plan to implement a planar Molecularly Controlled Semiconductor Resistor (MOCSER) gas sensor on both InAs and InN platforms for the ppt-ppm detection of NOx and H2O.

A vision subsystem… more
Abstract:Contamination of water supplies with toxic industrial chemicals (TICs) is a major concern for the U.S. military due to their worldwide prevalence and accessibility. Traditional, analyte-specific approaches are unfeasible to detect the approximately 70,000 potential TIC contaminants. … 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.
