Abstract:An ECC monitoring system in the form of a miniature Personal Computer Memory Card International Ass(PCMCIA) card is proposed. PCMCIA is a standard for credit card-sized ( 5mm x 86mm x 54 mm) peripherdesigned to use with notebook and handheld computers. The user can quickly remove and add these… more
Abstract:The objective of this research is to design a micromechanical temperature sensor capable of recording temperature extremes experienced beyond a preset value without the use of electrical power. The temperature sensor's memory will be mechanically induced. The sensor will be either in an… more
Abstract:The goal of this project is to develop new high-temperature heat flux sensors for heat transfer measurements in turbomachinery. The following obejctives will be pursued. Pototype sensors will be demonstrated which function at temperatures as high as 600C with a frequency response up to 50kHz. Using… more
Abstract:MICRO-DIFFRACTION-BASED CRYSTALLOGRAPHY IS ESSENTIAL TO MATERIALS DESIGN AND PROCESS UNDERSTANDING IN KEY INDUSTRIAL APPLICATIONS SUCH AS MICROELECTRONICS, SUPERCONDUCTIVITY, SOLAR ENERGY, STRUCTURAL COMPOSITES, AND METAL FORMING. THE SCANNING ELECTRON MICROSCOPE (SEM) CAN PROVIDE HIGH SPATIAL… more
Abstract:Microscopic measurement of surface topography is a continuing need in microfabrication technology and materials research. The aim of this research is to adapt the scanning electron microscope (SEM) to the quantitative measurement of a wide range of surface structures. The SEM is a widely used… more
Abstract:THE ALKAI METAL THERMAL OF ELECTRIC CONVERTER (AMTEC) IS A STATIC ENERGY CONVERSION DEVICE THAT OPERATES AT THERMAL TO ELECTRIC CONVERSION EFFICIENCIES THAT ARE INDEPENDENT OF SIZE, HAVE REACHED 19% AND ARE EXPECTED TO REACH 25% TO 30% IN EARLY 1995. THESE SYSTEMS OPERATE SILENTLY, WITH NO MOVING… more
Abstract:THIS PROJECT WILL EXTEND THE RESPONSIVITY OF CURRENTLY AVAILABLE LARGE-AREA AVALANCHE PHOTODIODES (APDS) INTO THE BLUE AND NEAR-UV REGION. APDS CAN OFFER SIGNIFICANT COST SAVINGS AND SUPERIOR PERFORMANCE (HIGH QUANTUM EFFICIENCY, COMPACTNESS, RUGGEDNESS, FREEDOM FROM AFTERPULSING, MAGNETIC FIELD… more
Abstract:A rang of AF activities generate wastewater containing oily substances, emulsion=stabilizing agents, and insoluble materials, including Aqueous, Film-Forming Foam (AFFF). US AF is searching for a cost effective method to handle the problem. This problem in reality refers to two issues: a)… more
Abstract:ARACOR proposes to develop image processing tools and integrate them into a software package running on UNIX workstations that can efficiently and quantitatively analyze computed tomography (CT) images of metal-matrix composites (MMC's). The software will provide numerical data to microstructural… more
Abstract:BESOI fabrication techniques will be evaluated to select an optimum approach for manufacturing ultrathin silicon films on 150- and 200-mm diameter wafers. A supplier of such BESOI material will be identified. The baseline will be the SiGe etch stop and strain-sensitive etch method which ARACOR has… more
Abstract:The investigators will test the feasibility of developing a 3D X-ray microtomography scanner for trstudies in small animals, as further described by their abstract: A 3-D Computed Tomographic scannerobservation of trabecular bone microstructure and density of laboratory animals is proposed. This… more
Abstract:Ladar is becoming increasingly important as a military surveillance, tracking and navigational tool. Current ladar systems use a single pixel combined with a mechanical, two-dimensional scanner to obtain an image. One laser pulse must be transmitted and received for each pixel in the image and… more
Abstract:An important and developing protein-crystallography field is time-resolved crystallography using syDynamic crystallography, however, imposes challenging requirements on detectors. As with other areascrystallography, the x-ray sources are advancing much more rapidly than the detector technologies.… 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.
