Abstract:THE UNITED STATES COAST GUARD (USCG) HAS LONG BEEN INTERESTED IN THE MITIGATION OF HAZARDS TO LIFE SAFTEY FROM FIRE ONBOARD SHIPS. THE DEVELOPMENT OF SUPERIOR FIRE RESISTANT COATINGS FOR GLASS-REINFORCED POLYMERIC (GRP) COMPOSITES, WHICH MAY BE USED AS BULKHEADS, DECKS AND INTERIORWALLS, IS ONE WAY… more
Abstract:We propose to develop new techniques for specimen preparation for the assessment of chromosome breakage in human cells by fluorescent in situ hybridization. The methods are applicable to automated image analysis at high resolution so that very low levels of chromosome damage will be detectable. We… more
Abstract:Marine simulators have historically used image generators designed for flight simulation. These systems do not provide the special effects required for marine simulation. The current generation of high-performance, low-cost graphics workstations, combined with commercial rendering software, provide… more
Abstract:We propose to develop and commercialize automated microscope instrumentation for the rapid, unattended assessment of chromosome breakage in human lymphocytes and other cells. The instrument will report, with very low estimation error rates, the proportion of cells suffering genetic damage. We… more
Abstract:We will develop and commercialize significantly improved software for digital enhancement of the dechromosome banding patterns in microscopic images. Recently developed wavelet transform and multiresanalysis techniques, used with modern computerized chromosome analysis, promise improved… more
Abstract:A NOVEL HIGH-PERFORMANCE HELIUM FREE PRECESSION (HFP) MAGNETOMETER IS USED IN GEOMAGNETIC FIELD MEASUREMENTS AND MAGNETIC GEOPHYSICAL EXPLORATION. RESEARCHERS ARE DEFINING A CONCEPT FOR A PORTABLE LASER-PUMPED HELIUM 3 MAGNETOMETER WHICH HAS SMALL SIZE , HIGH SENSITIVITY AND LOW POWER CONSUMPTION.… more
Abstract:A new laser protective material for protection from battlefield lasers is proposed. The material utilizes novel polarizing metal spheroid film (MSF) coatings which function as wavelenght-tuned polarizers in the spectral band from 400 nm to 2200 nm. Each MSF coating can be disigned to place the… more
Abstract:Nuclear angiography is considered the superior technique for accurate quantitative measurementof ventricular function. Despite this, a growing and predominant fraction of such measurements areperformed via echo- cardiography. Two factors have strongly influenced this shift to a less than… more
Abstract:Positron emission tomography (PET) is recognized as a superior diagnostic imaging techniquein a number of important clinical areas. However, it is currently relegated to a research role due to itsdependence upon in-hospital cyclotrons for radioisotope production with resultant high cost… more
Abstract:Millimeter wave imagers are being investigated as solutions to a variety of military and commercial problems. Millimeter waves penetrate fogs and clouds thus allowing for operation under conditions of adverse visibility. In addition, millimeter waves penetrate clothing and reveal concealed weapons… more
Abstract:The primary objective of this Phase I research is to develop a tool for evaluating the dependability of fault-tolerant computing systems. Dependability has traditionally been evaluated through combinatorial and Markov modeling. These analytical techniques have several limitations which can… more
Abstract:WE PROPOSE AN INNOVATIVE APPROACH WHICH LEADS TO THICK TUNGSTEN WIRES FULLY EMBEDDED IN SOLID DIAMOND SLAB. IN THIS APPROACH, THIN FILMS OF CHEMICAL VAPOR DOPOSITION (CVD) DIAMOND ARE COATED WITH A REFRACTORY METAL AND THE METAL IS PATTERNED. THESE PATTERNED LAYERS FILMS ARE STACKED AND PROPERLY… 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.
