Abstract:ARGTEC is pioneering the use of a new and innovative technology based on the theory of Attributed Relational Graph (ARG) in several application domains for content-based indexing and retrieval in large multimedia databases. We have achieved several breakthroughs in the development of this technology… more
Abstract:DESCRIPTION (provided by applicant): Gp160, the major surface protein on HIV, is composed of two key subunits, gp120 and gp41. Within either subunit there can be found regions of interest for vaccine development efforts; both gp120 and gp41 contain zones or sub domains that play fundamental… more
Abstract:Our objective is to develop highly automatic and scalable formal methods for malware detection. Existing tools for malware detection operate by searching for pattern matches with respect to signatures of known malware, and can account for only limited variations in the malware. That makes these… more
Abstract:The rapid increase in the use of the Internet in many aspects of our lives has led to an explosive growth in the spread of malware such as computer worms, viruses, and trojans. Security tools typically examine software for the presence of malware either by looking for specific byte signatures, or… more
Abstract:This Small Business Innovation Research (SBIR) Phase I research proposes to study the feasibility of automatic methods for analysis of counterexamples from formal verification of pipelined and superscalar microprocessors modeled at a high level of abstraction. Aries Design Automation has developed… more
Abstract:This SBIR proposal is for development of a ruggedized pressure sensor having capability to monitor its' own health, recalibrate if necessary, and wirelessly report its' status along with measured values. The proposed sensor substantially reduces the need for re-calibration by employing… more
Abstract:DESCRIPTION (provided by applicant): Continuous monitoring of physiological vital signs is a complex data intensive environment with patients routinely having 15-30 parameters measured using multiple monitoring devices. This wealth of data is central to the care of critically ill patients with… more
Abstract:With worldwide energy consumption becoming an epidemic and the future need for power conservation self evident, the improvement of power conversion systems and the reduction of energy waste has become a global priority. This project will develop very compact, light-weight, silicon carbide power… more
Abstract:In Phase I of this project, APEI, Inc. proved the feasibility of creating ultra-lightweight power converters (utilizing now emerging silicon carbide [SiC] power switching technologies) through the successful demonstration of power switch operation up to 500 oC. The goal of Phase II will… more
Abstract:This Small Business Innovation Research Phase I project seeks to prove the feasibility of creating high-temperature silicon-carbide (SiC) based motor drives for extreme environment exploratory robotic missions (such as Venus landers). SiC digital control ICs will be developed for controlling power… more
Abstract:This Small Business Innovation Research Phase I project seeks to investigate and prove the feasibility of developing ultra-wide temperature (-230 oC to +130 oC) motor drives utilizing Silicon-Germanium (SiGe) asynchronous logic digital control electronics. Asynchronous circuits… more
Abstract:This Small Business Innovation Research Phase I project seeks to develop and prove the feasibility of realizing high-voltage, high-power density Solid-State Fault Current Limiter (SSFCL) technology utilizing Silicon Carbide (SiC) thyristors.

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.
