Abstract:Currently, most antenna array designs are mechanically steered. However, as demand for higher performance antennas increases, an electronic replacement for the mechanical system becomes necessary. An alternative that may prove to be more cost effective is to use ferrite patch antennas as the… more
Abstract:We will evaluate the feasibility of using artificial intelligence software to assist in the identification and prosecution of health care fraud and abuse. Phase I includes the selection of three fraud and abHome Health Agencies, identifying the indicators prevalent in Home Health Care Agencies,… more
Abstract:THERE IS A NEED TO STIMULATE HAIR GROWTH FOR VARIOUS CONDITIONS OF ALOPECIA. IT IS ASSERTED THAT TO ACHIEVE HAIR GROWTH STIMULATION, BIOLOGICALLY ACTIVE COMPOUNDS MUST BE DELIVERED INSIDE HAIR FOLLICLE CELLS, AND THAT THE OPTIMAL WAY TO IDENTIFY ACTIVE COMPOUNDS AND METHODS OF THEIR DELIVERY IS TO… more
Abstract:In printed circuit board manufacturing, the patterning technology determines not only the ultimate packaging density, but also the economics of the entire process via throughput and yield. Conventional contact and projection printing methods have various shortcomings such as defect generation, mask… more
Abstract:We propose a unique GaN-Al(sub x)Ga(sub 1-x)N heterojunction based CCD for imaging in the ultraviolet (wavelengths less than 365 nm). Our proposed device will be solid state, TTL compatible and in it's final configuration solar blind. The Phase I program is aimed at establishing the technical… more
Abstract:Michellamine B is a potential anti-HIV agent isolated from the leaves of a Cameroonian vine,Ancistrocladus korupensis, which grows in the Korup region of Cameroon. Preclinical testing ofMichellamine B by the National Cancer Institute may be adversely impacted by raw materials availability,and the… more
Abstract:Many pyrotechnics contain valuable resources which could be used in commercial applications, for example metals (e.g. magnesium, aluminum); metallic salts of copper, strontium, and barium; oxidizer (e.g. sodium nitrate, potassium Perchlorate); binders such as viton, and dyes which have reclaimed… more
Abstract:Apollo Enterprise proposes to develop a highly sensitive, remotely deployable sensor system for hydrocarbon detection in waste water. The novel device is designed to monitor the hydrocarbons in waste water in real time and will serve as a tool to minimize the release of contaminated water into local… more
Abstract:Health professionals must often analyze disease cluster allegations made by concerned citizens who sense patterns within small structured environments. Examples include households, families, sibships, wards, cellblocks, classrooms, job types, age classes, and locations within a building. It is… more
Abstract:Three approaches -- a wake-integral procedure, a viscous theory of aerodynamics and an integro-differential method for Navier-Stokes flows -- will be fully developed and consolidated to create a new technology for studies of aerodynamic drag associated with unsteady flows. These new approaches deal… more
Abstract:WE HAVE BEEN DEVELOPING A NEW MEANS TO ELECTRICALLY STUDY ANIMAL CELLS GROWN IN TISSUE CULTURE AND INTEND TO MAKE A COMMERCIAL DEVICE SUITABLE FOR USE IN THE MEDICAL/BIOLOGICAL RESEACH AND TESTING MARKET. THE INSTRUMENTAL METHOD, REFERRED TO AS ECIS (ELECTRIC CELL-SUBSTRATE IMPEDANCE SENSOR), IS A… more
Abstract:There is a global trend towards utilization of satellite communications for information services. Equivalent system temperature, Ts, is a significant parameter in quantifying the antenna system/link performance, because it represents the noise power spectral density in antenna system… more
Abstract:A new Navy process substitutes low toxicity trivalent chromium for toxic hexavalent chromium in aluminum conversion coatings. Further work is needed to investigate variations on the original formulations, with special consideration to formulas useful with common alloys of aluminum. Both a yellow and… more
Abstract:The adaptive single user receiver invented at AF LAB has been shown to suppress multiuser and certain forms of narrow-band interference in adecision directed mode during the entire transmission, without requiring knowledge of other users spreading codes, timing or phase information in… more
Abstract:This project will develop a chip package that can be tailored to match the thermal coefficient of expansion (TCE) of semiconductor chips and has an order of magnitude higher thermal conductivity than conventional ceramic packaging materials. The Phase I project will focus on selection and… 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.
