Abstract:The ultimate aim of this research is the development of an instrument capable of detecting and measuring the presence of an electrostatic field created by local static electric charge. The sensor operates on a physical principle not yet exploited for field measurement. The final instrument will be… more
Abstract:Active clearance control promises considerable improvements in rotating component efficiencies and compressor surge margin. These improvements are essential to meet stringent performance requirements for next generation propulsion systems. The improvements are more pronounced for small engines,… more
Abstract:Propulsion subsystems of future flight vehicles will run to higher thermal and aerodynamic loads for increased efficiencies. Increased loading and operating requirements cause serious mismatch between stages and components during off-design conditions with attendant compromise on stability margin.… more
Abstract:Work by M. Binder and the army ETDL has shown that the RF plasma treatment of capacitor films, electrode foils and wound rolls, can result in significant and in some cases dramatic improvements, in the electrical breakdown strength of certain capacitor films and capacitor rolls. In this… more
Abstract:ADDRESSING THE NEED FOR INCREASINGLY LIGHTER STRUCTURAL COMPOSITES WITH IMPROVED THERMAL AND ELECTRICAL PROPERTIES, A NEW METHOD IS PROPOSED FOR THE PRODUCTION OF ECONOMICAL HIGH TEMPERATURE POLYMER-METAL COMPOSITES. THESE MATERIALS ARE PRODUCED BY A PATENTED ULTRA HIGH SPEED VACUUM PROCESS, THAT… more
Abstract:THE RECENT AVAILABILITY OF THE CARBON ICOSOHEDRAL MOLECULES, THE FULLERENES, AND THE DISCOVERY OF SUPERCONDUCTIVITY IN ALKALI DOPED FULLERENE DERIVATIVES OPENS NEW AVENUES OF INVESTIGATION INTO SUPERCONDUCTING DEVICES. IN PARTICULAR, THE FULLERIDES ARE PREDICTED TO ACHIEVE HIGH PERFORMANCE AS… more
Abstract:The principal goal of the Phase I program is to demonstrate the feasibility of predicting the likelihood of injury by developing an injury-predicting criterion for one segment of the human body. The Phase I effort will concentrate on identifying relevant neck-related injuries, determining loads and… more
Abstract:Ground troops have the need for a personnel armor that will provide them protection from multiple battlefield threats such as fragmentation nd small-arms rifle fire up to .30 cal. Simula will develop an armor system from two new materials which were recently tested and yielded promising results. A… more
Abstract:The objective of the proposed work is to conveive restraint locking devices capable of locking aviator torso restraints with less than 2.5 cm of webbing travel. Existing aviator torso restraints depend on sensing webbing acceleration that has reached a critical threshold. However webbing motion is… more
Abstract:A multichannel array detector for mass spectroscopy with a novel configuration will bedeveloped. A triple conversion approach is used whereby incident ions are used to generate secondaryelectrons which strike a scintillator which produces optical photons. The photons are detected with animaging… more
Abstract:VARIABLES THAT MIGHT LEAD TO WIDER ADOPTION OF INTEGRATED PRESCHOOL PROGRAMS INCLUDE EXPANSION OF THE WAY IN WHICH WE MAKE DECISIONS AND THE MANNER IN WHICH RELATED SERVICES ARE DELIVERED. EVALUATION EFFORTS SHOULD BE EXPANDED TO INCLUDE THE IMPACT OF VARYING METHODS OF INTEGRATION. THIS PROJECT… more
Abstract:We propose development of a miniaturized displacement sensor suitable in size and cost for mass-quantity use in adaptive and active optics applications. These sensors will be designed for the very high resolution required for precise control of local mirror shapes, segment location, and edge… more
Abstract:THE GOAL OF THIS PROJECT IS TO DEVLEOP AN EASY-TO-USE, MICROCOMPUTER-BASED SYSTEM FOR FACILITATING THE DESIGN, IMPLEMENTATION AND ANALYSIS OF RECEIVER OPERATING CHARACTERISTIC (ROC) EXPERIMENTS. THE SPECIFIC PHASE I GOAL IS TO DEMONSTRATE THE FEASIBILITY OF DEVELOPING SUCH A SYSTEM BY SPECIFYING THE… more
Abstract:The high false-negative rate from Papanicolaou (Pap) smears has motivated the use ofcolposcopy to perform visual inspection of the uterine cervix. It has made a tremendous impact on theability of physicians to perform accurate punch biopsies for histological analysis. However, the difficultyin… more
Abstract:THIS PROGRAM WILL DEVELOP A NEW COMPUTER CONTROLLED STEREOLITHOGRAPHY PROCESS FOR THE MANUFACTURE OF REINFORCED CERAMIC COMPOSITE PARTS. PHASE I WILL DEMONSTRATE A WORKING SYSTEM THAT WILL DIRECTLY READ A COMPUTER CAD DRAWING OF A SIMPLE COMPONENT AND THEN GENERATE THE ACTUAL GREEN COMPOSITE PART.… 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:MANY AGRICULTURAL CROPS REQUIRE APPLICATION OF PESTICIDES AND/OR HERBICIDES. THE APPLICATOR'S JOB INCLUDES TWO TASKS. FIRST IS TO ACCURATELY PLACE A SPECIFIED UNIFORM SPRAY DENSITY ONTO THE CROP OR SOIL SURFACE. SECOND IS TO MINIMIZE OR ELIMINATE DRIFT OF PARTICLES INTO SENSITIVE AREAS SUCH AS HOMES… 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.
