Abstract:Maintenance of Air Force turbine engines is hampered by threaded fasteners which have seized and cannot be removed, particularly in high-temperature turbine sections. Removal of these fasteners for routine maintenance often results in galled, seized or broken parts, with accompanying damage to the… more
Abstract:USING A TIME TESTED, SUCCESSFULLY IMPLEMENTED COMPUTERIZED INTEGRATED CASE MANAGEMENT INFORMATION SYSTEM AS A BASE, WE WILL DESIGN AN INTEGRATED COMPUTER-AIDED SYSTEM ENGINEERING (I-CASE) TOOL, THAT WILL (A) BE READILY ACCEPTABLE TO A WIDE VARIETY OF CASE MANAGEMENT PROFESSIONALS NATION-WIDE (B) CAN… more
Abstract:THREE AREAS OF ACTIVE MISSILE WING RESEARCH WILL BE PURSUED. THE FIRST SECTION WILL EVALUATE THE MATERIALS TO BE USED IN THE INFLATABLE WING SPARS, RIBS, SKINS, PRESSURE BLADDERS AND ACTIVE ELEMENTS. SPECIMENS OF HIGH ORTHOGONALITY COMPOSITES (POLYURETHANE-GRAPHITE) WILL BE CONSTRUCTED ALONG WITH… more
Abstract:Embryology is a fundamental element of human biology that provides a necessary foundation for gross anatomy and understanding congenital anomalies as encountered in clinical medicine. Embryological development is a dynamic and interactive process that is difficult to learn through traditional… more
Abstract:The project proposed for funding here deals with the expansion of a next generation model in semiempirical molecular orbital treatments. The new approach is called SAM1 (for Semiempirical ab initia Method Version 1). SAM1 is different from present methods in that it explicitly computes two-electron… more
Abstract:ADVANCED LOW HEAT REJECTION (LHR) ENGINE LIFE EXPECTANCY HAS BEEN LIMITED ALMOST ENTIRELY BY PERFORMANCE OF THE LIQUID LUBRICANT COMPONENT OF THE TRIBOLOGY SYSTEM. THE ADVANCED INTEGRATED PROPULSION SYSTEM (AIPS) DIESEL ENGINE IS A LEADING CANDIDATE FOR THE ARMY'S BLOCK III ENGINE, TO BE USED IN THE… more
Abstract:1A multi-segmented dynamic leading-edge flap system is proposed as a candidate for lift enhancement through dynamic flow manipulation. Delta wings with sweep angles of 60 degrees or more will be fitted with the proposed leading-edge device of 3 or more flaps. Each flap is controlled with a… more
Abstract:LATERAL EARTH PRESSURE IS FUNDAMENTAL TO MUCH OF SOIL MECHANICS, AND VITAL TO THE SOLUTION OF MAY PRACTICAL PROBLEMS INCLUDING COMPUTERIZED SOLUTIONS FOR BEARING CAPACITIES AND FOR STABILITY OF TUNNELS, SLOPES AND WALLS. UNFORTUNATELY, THE KEY ROLE OF LATERAL STRESS HAS TENDED TO BE PASSED OVER IN… more
Abstract:THERE HAS BEEN A DRAMATIC INCREASE IN EGG BORNE SALMONELLA ENTERITIDIS (SE) INFECTION IN HUMANS. FROM JANUARY 1985 THROUGH 1988, THERE WERE 4976 REPORTED SE CASES IN 140 OUTBREAKS IN THE NORTHEASTERN U.S., RESULTING IN 896 HOSPITALIZATIONS AND 30 DEATHS. SIXTY FIVE (73%) OF OUTBREAKS WITH IDENTIFIED… more
Abstract:THE PURPOSES OF THIS PROJECT ARE TO: A) DEVELOP A SERIES OF COOPERATIVE STRATEGIES THAT TEACHERS CAN TEACH TO THEIR STUDENTS AS THEY WORK TOGETHER WITHIN COOPERATIVE GROUP STRUCTURES IN MAINSTREAM CLASSROOMS; AND B) DEVELOP AND EMPIRICALLY VALIDATE THE MATERIALS AND PROCEDURES THAT ARE NECESSARY FOR… more
Abstract:THIS DOCUMENT DESCRIBES ELECTROLUMINESCENT (EL) LAMPS THAT WILL HAVE LUMINANCE UP TO 300 FOOT-LAMBERT. THE COST OF EACH LAMP WILL BE UNDER $40.00 PER SQUARE METER COMPARED TO A PRICE OF $600.00 PER SQUARE METER IN THE U.S. MARKET. THE EFFICIENCY OF EL LAMPS IS COMPATIBLE TO EFFICIENCY LIDERS SUCH AS… more
Abstract:THIS EXPLORATORY DEVELOPMENT'S GOAL IS TO PINPOINT SOURCES AND MANUFACTURERS OF STATE-OF-THE-ART MICROPHONE TO BE USED IN THE U.S. ARMY NBC PROTECTIVE MASK BY COMPLETING THE FOLLOWING OBJECTIVES: 1) NEEDS ASSESSMENT: 1. END USER, 2. DESIGNERS, 3. MATERIALS. 2) RESEARCH FOR ADVANCED TECHNOLOGY… more
Abstract:THIS INNOVATION PROPOSAL WILL RESEARCH THE FEASIBILITY OF DEVELOPING A HIGHLY ACCURATE, LOW COST POLYMER SENSOR, UTILIZING THE PIEZOELECTRIC PROPERTIES OF PVDF COMBINED WITHA DIAPHRAGM AND/OR OTHER FORCE SENSITIVE STRUCTURE TO PRODUCE A PRESSURE SENSOR. THE POLYMER SENSOR WILL BE EASILY ADAPTED TO… more
Abstract:A RAPID FIELD TEST IS PROPOSED TO EVALUATE THE PERMEABILITY OF OPEN-GRADED ROAD BASES AND OTHER DRAINAGE LAYERS. THE SAME TEST ALSO SHOULD BE ADAPTABLE TO EVALUATE PERMEABILITIES OF OTHER EXPOSED PAVEMENT LAYERS INCLUDING THOSE COMPOSED OF BITUMINOUS OR PORTLAND CEMENT CONCRETES, AS AN INDEX TO… 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.
