Abstract:Physical Unclonable Functions (PUFs) are a less expensive and more secure alternative to the use of non-volatile memories to provide the secret storage. A PUF is a function that maps a set of challenges to a set of responses based on an intractably complex physical system. Given a fixed challenge,… more
Abstract:The ability to accurately catalog and search through vast repositories of human images has been difficult to achieve for several reasons. The most common approach to this problem involves the manual tagging of images with textual descriptions. Unfortunately, manual tagging is a laborious process,… more
Abstract:Overall biometric system performance depends on data quality, the strength of the biometric matching algorithms, the compatibility of the data quality with the matching algorithms, and the overall quality of the integrated system. For long-range face image acquisition and processing for tactical… more
Abstract:This Phase II effort will expand the Attribute-based advanced face technology to TRL4 or more, to improve the user interfaces issues for this novel technology and to advance the fundamental understanding of Attributes and how they are efficiently computed and their stability properties. It will… more
Abstract:The Anti-Submarine Warfare (ASW) capabilities of surface combatants, often operating in carrier or expeditionary strike groups, rely heavily on active sonar for detection due to the quieting of adversary submarines. These combatants have full knowledge of their own transmissions however; they employ… more
Abstract:As a technology that would dramatically reduce both our dependence on foreign oil and lower carbon dioxide emissions, stationary and transportation fuel cells are very attractive. Although the stationary fuel cell market is well establishes and prototype automotive and bus vehicles have successfully… more
Abstract:ABSTRACT: Microbial contamination in kerosene based aviation fuels has been a problem for the USAF since the 1960"s. Antimicrobial effect of earlier used fuel system icing inhibitor (FSII) became an initial solution to this problem, but later, such fuel additives were banned due to their… more
Abstract:DESCRIPTION (provided by applicant): The primary objective of this proposal is to develop and commercialize a safe and more effective therapy for the treatment of Crohn's Disease, an inflammatory bowel disease. Crohn's Disease is a chronic inflammatory disorder of the gastrointestinal… more
Abstract:Existing techniques for level 1 fusion of association statements in large RDF data stores have proven inadequate to the challenge of entity disambiguation from multiple intelligence sources. The resulting entity and association uncertainty causes problems of missed associations, redundant RDF… more
Abstract:C++ is a key software technology for programming embedded systems and sophisticated applications, widely used for mathematical modeling codes fundamental to modern physics and engineering. Such codes are complex, often requiring high performance, and are built over long periods as scientists come… more
Abstract:A hit grid system that sends telemetry from optoelectromechanical sensors on a test target, offers high quality information which cannot be easily duplicated using other techniques. When such a system can also incorporate other target sensor data into the telemetry stream while improving size,… more
Abstract:DESCRIPTION (provided by applicant): This Phase II SBIR project is aimed at developing a novel type of drugs, termed SNX9-class compounds, with a unique combination of two anticancer activities. The first is a selective antiproliferative effect on tumor cells relative to normal cells. The second is… more
Abstract:DESCRIPTION (provided by applicant): This project is for the development of software with research and clinical applications in the hearing sciences. In the research area, the software will allow investigators to work at a higher level of abstraction,providing monitoring and control applications… more
Abstract:The long term goal of this project is to eliminate insect pests from the US food and feed supply with a sensor device, minimize exposure of humans and animals to residual chemicals or insecticides, and reduce financial losses due to grain damage. The lesser grain borer (LGB) is a devastating,… more
Abstract:The Formosan subterranean termite (Coptotermes formosanus, FST), an exotic, cryptic pest, causes about $1 billion damage in the US annually (Lax and Osbrink). Unlike native species, this aggressive termite attacks living trees, potentially threatening southern forests and the urban/forest interface.… more
Abstract:ABSTRACT: It is proposed to develop an innovative structured class of devices with directive emission and transmission that utilize metamaterial concepts. The proposed structures will be thin films with electromagnetic responses that can be systematically manipulated in the infrared region to… more
Abstract:It is proposed to incorporate electromagnetic metamaterial designs into a new class of EM chaff designed for operation across the 2 - 18 GHz region. Metamaterials can be tailored to produce unique EM responses, including as near perfect absorbers, for use as EM countermeasures. EM metamaterials can… more
Abstract:SensorMetrix proposes to develop and demonstrate acoustic cloaking. Further, SensorMetrix will analyze the performance, determine methods to use as countermeasures. These efforts will be both analytic and experimental.
Abstract:Electromagnetic Interference (EMI) is a major concern for all types of communications systems. Cosite EMI, in which collocated systems are the primary source of EMI, demands much consideration because of the high power levels received due to low isolation between the transmit and receive antennas.… more
Abstract:Under this STTR, Sentient Corporation, along with the Ohio State University GearLab as a research partner, will develop a probabilistic physics-based damage modeling tool for the simulation of superfinished gear components. This model will consider critical surface, material, and load parameters for… more
Abstract:Sentient will develop enhanced fretting fatigue analysis software with rigorous consideration of surface roughness effects in the stick/slip phenomena and fatigue. This will be coupled with an analysis of the stresses and resulting degradation in the material. Sentient will utilize diagnostic data… 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.
