Abstract:DESCRIPTION (provided by applicant): Lyme disease, due to infection with the Ixodes tick-transmitted spirochete Borrelia burgdorferi, is the most common vector-borne disease in the United States, with more than 28,000 cases reported annually. The infectioncan remain localized to the skin or… more
Abstract:DESCRIPTION (provided by applicant): The goal of the proposed research is to develop a series of diagnostic assays that will detect specific types of enterotoxigenic Bacteroides fragilis (ETBF). ETBF has been shown to cause diarrhea as well as bowel inflammation and colitis. Experimental evidence… more
Abstract:DESCRIPTION (provided by applicant): Exposure to isocyanate, the essential cross-linker for making polyurethane, is a leading cause of occupational asthma world-wide. Three major types of isocyanate are used commercially, methylene-diphenyl diisocyanate (MDI) and toluene diisocyanate (TDI), or… more
Abstract:A Towed Array Control Module (TACM) will be developed to control the configuration of single and multi-line towed arrays by applying the appropriate force vector at the tail end, while reducing drag. The TACM is a streamlined module with some maneuvering ability of its own that can adjust the… more
Abstract:The SK-LVC Phase II proposal requires the employment of new and evolving technologies in the areas of power generation, autonomous operation and control of both surface and undersea unmanned vehicles, and operation of vehicles across the operational environment continuum from subsurface, surface,… more
Abstract:DESCRIPTION (provided by applicant): Despite the rise of bacterial resistance to antibiotics, the development of new antibiotics is on the decline. Methicillin-resistant Staphococcal aureus infections (MRSA) in the United States has been increasing, causing 19,000 deaths per year in the United… more
Abstract:DESCRIPTION (provided by applicant): Fungal infections continue to be a major cause of morbidity and mortality among HIV- infected patients. At present, there are only three classes of antifungal agents that are suitable for the treatment of AIDS-relatedfungal infections, but these medications are… more
Abstract:An accurate assessment of composite structural performance and proactive component and system life management strategies requires quantitative information on the damage states of the components. Recent advances in infra-red (IR) sensing and data processing technologies have enabled real-time… more
Abstract:Helicopters with articulated rotor blades are subject to the well-known ground resonance where the rotor lag mode interacts, in an unstable fashion, with fuselage roll. To eliminate this ground resonance, both lag dampers and fuselage roll dampers are required. The Sikorsky UH-60 helicopter platform… more
Abstract:ABSTRACT: At present, the common practice in the fighter aircraft industry is to use touch probes as secondary measurement systems to maintain tight machining tolerance control. The current touch-probe inspection process renders the typical milling machine idle while features of the machined part… more
Abstract:ABSTRACT: Aircraft structural components are prone to damage typically assessed by various NDE tools. Damage to the aircraft structural components decreases operational readiness and compromises safety if improperly maintained; however, frequent inspections and maintenance is expensive. CBM+… more
Abstract:To accurately account for effects of environmentally assisted cracking in the overall structural life, quantitative information on the sustained residual stresses needs to be identified. Current methods for residual stress evaluation lack the required level of quantitative accuracy to permit the… more
Abstract:Optoelectronic integrated holds the key to higher performance, reduced mass and radiation-hard space systems. A special need is increased flexibility of phased arrays for communication and detection. Currently RF arrays use ferrite waveguide elements for phase shifting which are both bulky and… more
Abstract:The quest for deepened understanding of the origin of the universe requires continued search for elementary particles, for which high-energy accelerators are necessary tools. Reducing the size, complexity, and cost for future accelerators is essential if they are ever to be built. New technologies… more

Abstract:In a two-beam accelerator, a high-current drive beam imparts energy to a low current test beam by generating microwave power that flows from one beam to the other. The largest project of this sort is CLIC, located at CERN in Geneva, Switzerland, that is being designed for operation at an… more
Abstract:Thermionic cathodes are in use in an overwhelming majority of vacuum electronics devices, including high-power RF sources used to drive particle accelerators. These cathodes do not operate reliably or have long lifetime if their current density exceeds 5-10 Amperes/cm2. Artificial diamond and… more
Abstract:The overall goal of this proposed program (through Phase III) is to develop a chemical warfare agent analyzer capable of detecting vapor phase agents at 10-7g/m3 in less than 1 minute. This will be accomplished by developing a method to produce novel localized surface plasmon resonance (LSPR)… more
Abstract:The overall goal of this proposed program (through Phase III) is to develop a chip-scale assay that can detect, identify, and quantify the presence of Category A (or B) bioagents in water at the required sensitivity (e.g. 8000 B. anthracis spores or 50µg of ricin per liter water) within 10 minutes.… 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.
