Abstract:The process of designing and evaluating advanced aircraft coatings can be made more efficient, more robust, and less expensive through application of highly accurate and flexible computer models. The General Scattered Light (GSL) model is such a signature analysis tool, but its potential is… more
Abstract:SOLID STATE LASER SOURCES CURRENTLY AVAILABLE FOR MEASURING GREENHOUSE GASES, COMBUSTION PRODUCTS, AND OTHER SPECIES ACROSS THE 3 TO 30 MICRON REGION ARE LEAD SALT DIODE LASERS WHICH OPERATE AT LIQUID NITROGEN TEMPERATURES. PRACTICAL PROBLEMS INCLUDE THE NEED FOR CRYOGENIC COOLING, ERRATIC TUNING… more
Abstract:The problem addressed in this project is the need to monitor oxides of nitrogen(NOx, ie NO and NO2) levels in the combustion gases of stationary sources suchas power plants in order to facilitate on-line control of the scrubbers that willbe used to remove those pollutants. Since the measurements… more
Abstract:Smart IR technology has advanced at a rapid pace over the last two decades, pushed along by primarily defense-related requirements. This includes such breakthroughs as Acousto-Optic Tunable Filters and microbolometer detector arrays. Coupled with the continuing growth in microprocessor power, this… more
Abstract:RESEARCHERS ARE DESIGNING, DEVELOPING, AND APPLYING NOVEL LASER DIAGNOSTICS TO THE STUDY OF INTERACTING DROPLETS AND SPRAY VAPORIZATION AND COMBUSTION AS APPLIED TO LOW GRADE FUELS. THE LACK OF FUNDAMENTAL UNDERSTANDING OF SPRAY COMBUSTION AND BURNING CHARACTERISTICS OF LOW GRADE FUELS CALLS FOR… more
Abstract:Development of advanced diagnostic techniques and spray characterization methodologies are essential to the understanding of the complex spray process and for validating state-of-the-art CFD codes that are available for describing the spray process. Novel diagnostic techniques and measurement… more
Abstract:A real-time non-intrusive turbine engine exhaust particulate monitor, based on simultaneous multi-wavelength backscattering and extinction measurements, has been proposed herein. The objective is to mathematically invert the simultaneously measured laser light extinction and light scattering at… more
Abstract:THE FEASIBILITY OF USING A NOVEL LIGHT SCATTERING INTENSITY RATIO TECHNIQUE FOR THE SIMULTANEOUS MEASUREMENTS OF THE SPEED AND SIZE OF NON-SPHERICAL PARTICLES WILL BE EXAMINED IN PHASE I. THE TECHNIQUE MAKES USE OF TWO CONCENTRIC LASER BEAMS WITH DIFFERENT DIAMETERS AND THE AMPLITUDE OF THE SIGNALS… more
Abstract:We will develop a commercial kit so that biologists can readily study tissues under conditions of hgradient culture. Here, as in nature, stratified epithelia adhere to their supporting stroma at a reRenewal of epithelium occurs adjacent to the interface, and all metabolic exchange is by diffusion… more
Abstract:The Aeronix Phase I task will address the problem of incorporating Imagery/High Speed Fleet Broadcast (HSFB) Receive Only Capability into the Multi-Mission Advanced Tactical Terminal (MATT) System. The significance of this effort is providing additional capability for field users of the MATT system.… more
Abstract:We will design a unique device that would clean and recirculate indoor air for the purpose of contrtuberculosis bacilli and other micro-organisms. The device would be based on the principle of particimpaction, a well-understood mechanism which is very effective for particles greater than 1… more
Abstract:The need for an automated target recognition system that can identify a target from a noisy image, irrespective of the target's orientation or size is identified. A novel pulse-coupled neural network is proposed to meet this need. The first step is to capture the image. Next, a neural network is… 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.
