Abstract:BERYLLIUM (BE) IS A CANDIDATE MATERIAL FOR DIVERTERS IN NUCLEAR FUSION REACTORS. HOWEVER, THE USE OF BE IS LIMITED BY ITS MODERATE THERMAL CONDUCTIVITY (218 W/M-K) AND BRITTLENESS, BOTH OF WHICH RESULT IN A LOW THERMAL SHOCK RESISTANCE. THE MODERATE THERMAL CONDUCTIVITY AND POOR MECHANICAL STRENGTH… more
Abstract:An approach is presented to solve both the data fusioin problem, and the space object model building requirement for the Air Force Phillips Laboratory. Artificial neural network (ANN) technology provides a number of tools that form the basis of this proposal and the foundtion for the solution to the… more
Abstract:LOCAL AGENCIES AND COUNTY GOVERNMENTS ARE CONTINUALLY IN NEED OF DRUG ABUSE PREVALENCE ESTIMATES FOR PLANNING AND RESOURCE ALLOCATION. SEVERAL MATHEMATICAL MODELS EXIST, SUCH AS, MULTIPLE RECAPTURE CENSUSES AND SYNTHETIC ESTIMATORMETHODS. THESE MODELS CAN BE ADAPTED FOR USE WITH "STATE-OF-THE-ART"… more
Abstract:ADVERSE DRUG REACTIONS ACCOUNT FOR A SIGNIFICANT PROPORTION OF ALL U. S. HOSPITALIZATIONS; ESTIMATES RANGE AS HIGH AS 18 PERCENT OF HOSPITAL ADMISSIONS. THE PHASE I OBJECTIVE IS CREATION OF A MICROCOMPUTER-BASED PROTOTYPE FOR PHYSICIANS AND PHARMACISTS THAT WOULD USE INTEGRATED-CIRCUIT CARDS (SMART… more
Abstract:This project addresses the development of software technologies to collect, analyze, and display test data from adaptive optics control systems. Innovative technologies are devised which allow efficient processing of data from multiple-input/multiple-output (MIMO) systems involving deformable… more
Abstract:There is a need for a reliable High Energy Laser Wavefront Analyzer (HELWA) to be used for beam quality testing at the Army's High Energy Laser Systems Test Facility (HELSTF). Accurate HEL wavefront measurements are critical to HEL device performance evaluation. Current devices are inflexible and… more
Abstract:DUAL ENERGY IMAGING HAS THE POTENTIAL TO ADD NEW AND POWERFUL DIAGNOSTIC CAPABILITIES TO A MEDICAL X-RAY EXAMINATION. UNLIKE AN ORDINARY X-RAY IMAGE, DUAL ENERGY IMAGE DATA CAN BE PROCESSED TO GIVE INFORMATION ABOUT THE CHEMICAL COMPOSITION OF BODY TISSUES. THIS NEW INFORMATION CAN BE USED, FOR… more
Abstract:CURRENT COROPUTER ANALYSIS OF BUBBLE-SUBMERGED STRUCTURE INTERACTION, DUE TO CONVENTIONAL WEAPONS, IS EXTREMELY RESOURCE INTENSIVE. THEREFORE, IT IS VERY DIFFICULT TO REPLACE FULL SCALE LIVE FIRE TESTING OF SUBMERGED STRUCTURE WITH SCALE TESTING OF SUBMERGED STRUCTURES AND COMPUTER ANALYSIS. THE… more
Abstract:A new method for silencing internal machinery generated torpedo noise is proposed. This innovative solution to the problem has the added capabilites of: controlling on a wavevector basis the acoustic signal radiated by the torpedo and simulation of boundary layer excitation on a torpedo hull. The… more
Abstract:DISEASE CONTROL, A MAJOR PROBLEM IN THE AQUACULTURE INDUSTRY, REQUIRES ADMINISTRATION OF PHARMACEUTICALS TO WHOLE POPULATIONS OF FISH. AVAILABLE MODES OF DRUG DELIVERY, (ORAL, IMMERSION OR INJECTION) ARE INEFFICIENT OR NOT PRACTICAL ON A LARGE SCALE. OUR OBJECTIVE IS TO DEVELOP AN EFFICIENT… more
Abstract:SWINE DYSENTERY (SD) HAS BEEN ESTIMATED TO COST SWINE PRODUCERS IN EXCESS OF $180 MILLION ANNUALLY, AND IS QUARANTINABLE IN MOST STATES. CONFIRMATION OF THE DISEASE IS BASED ON THE DETETION OF THE BACTERIA, SERPULINA HYODYSENTERIAE, FROM INFECTED PIGS. AN ACCURATE DIAGNOSIS OF SD CURRENTLY INCLUDES… more
Abstract:Existing balloting codes do not consider all of the forces and interactions that contribute to balloting of hypervelocity projectiles. This effort will result in the definition of a complete mathematical model and the design of an appropriate, user friendly, computational model to predict… more
Abstract:Surgeons performing arthroplasty on painful, misshapen, arthritic hand joints do not have the choice of replacing the damaged joint with a prosthesis that will restore near natural movement as they would if a hip joint were being replaced. There are no effective finger joint replacements available.… more
Abstract:THIS RESEARCH SEEKS THE DEVELOPMENT AND DEMONSTRATION OF A MODEL THAT REPRESENTS THE GROUP DECISION-MAKING PROCESSES TAKING PLACE INSIDE THE CONTROL ROOM OF A NUCLEAR POWER PLANT UNDER BOTH NORMAL AND ABNORMAL OPERATING CONDITIONS. COGNITIVE DECISIONS, TEAM EFFECTS, AND DYNAMIC FEATURES ARE AMONG… more
Abstract:The research will investigate a uniquely configured optical to tactile converter which packages both the optical camera and a miniaturized vibrotactile display into a compact handheld configuration. The increased haptic awareness afforded to the user by this configuration is expected to improve the… more
Abstract:This research will investigate a blind mobility aid which uses kinesthetic feedback to intuitively communicate to the user the range and texture of surfaces in the extended environment. The handheld device will contain an infrared optical ranging module with the range output. The sensitivity 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.
