Abstract:Recent developments in composites based on aluminides of titanium and nickel have shown the need for novel methods of production of cost effective methods of manufacture of continuous and discontinuous reinforcement materials. Currently, such materials as SiC provide a source of matrix fiber. In… more
Abstract:ACCIDENTS INVOLVING THE INTRODUCTION OF AIR EMBOLI IN THE CORONARY OR CEREBRAL CIRCULATION PATHS THROUGH CARDIOTOMY OR PUMP OXYGENATOR PROCEDURES CAN RESULT IN DEVASTATING INJURY. WE WILL DEVELOP A NON-INVASIVE MECHANISM FOR QUICKLY AND ACCURATELY DETECTING THE PRESENCE OF AIR EMBOLI IN THE INFUSION… more
Abstract:The research is intended to address the problem of extravasation events in the neonatal and pediatric patient population. Extravasations of intravenous fluids in children can have serious consequences when gross extravasations occur. Skin necrosis can occur which may require treatment with skin… more
Abstract:DEVELOPMENT OF A SYSTEM ARCHITECTURE TARGETED SPECIFICALLY FOR HEAD MOUNTED DISPLAYS AND A PERSONAL SYNTHETIC ENVIRONMENT (VIRTUAL WORLD) INTERFACE IS PROPOSED. THIS NEW ARCHITECTURE WILL ELIMINATE MANY OF THE TRADITIONAL PROBLEMS ASSOCIATED WITH HMDS. PHASE 1 WILL INCLUDE, AS PROOF-OF-PRINCIPLE,… more
Abstract:DESIGN AND DEVELOPMENT OF A SEMI-AUTOMATED FLIGHT EVALUATION SYSTEM (S AFES) IS PROPOSED. THIS WILL INVOLVE THE INTEGRATION OF CUSTOM SOFTWARE, A MICROCOMPUTER, SOFTWARE UTILIZED BY THE USAF IN LEARNING ABILITIES MEASUREMENT, AND PRECISION AIRCRAFT INSTRUMENTATION. SAFES WILL IMPROVE FLIGHT TRAINING… more
Abstract:THIS PROJECT IS DEVELOPING A NEW SOLID-STATE BIOSENSOR TECHNOLOGY FOR BIOLOGICAL MEASUREMENTS. THIS TECHNOLOGY IS BASED ON THE MERGING OF TWO RELATIVELY DIFFERENT TECHNOLOGIES: NUCLEIC ACID PROBES (DNA HYBRIDIZATION TECHNOLOGY) WITH ACOUSTIC PLATE MODE (APM) MICROSENSORS. RECENT ADVANCES IN THE… more
Abstract:This program on high-strength piezocermaic fibers probes a critical gap in the technology of smart materials which interconvert electrical and mechanical energy. Strong piezoceramic fibers that can function as load bearing members in structures and survive the large mechanical strains encountered in… more
Abstract:To continue the development of low cost carbon composite material, this program is intended to demonstrate the ability to fabricate net shape tubular space truss components using co-braided carbon and thermoplastic (PEEK) yarns. The thermoplastic yarn, when processed through an autoclave cure using… more
Abstract:A SEVERE DECLINE IN LANDINGS OF HADDOCK (MELANOGRAMMUS AEGLEFINUS) IN THE NORTHEASTERN U.S. HAS RESULTED IN PRICES SIMILAR TO THOSE OF SALMON AND MARKET RELIANCE ON IMPORTS. THIS CREATES AN OPPORTUNITY FOR HADDOCK CULTURE IN MAINE UTILIZING THE FACILITIES ALREADY IN PLACE FOR SALMON AQUACULTURE.… more
Abstract:THE OBJECTIVE OF THE PROPOSED RESEARCH IS TO EXPAND AND IMPROVE THE MATHEMATICAL DESCRIPTION AND QUANTITATIVE UNDERSTANDING OF INCREMENTAL COMPOUNDING AND BENDING PROCESSES USED IN THE MANUFACTURE OF COMPOUND-CURVED METAL PLATES FROM FLAT SHEET STOCK. THE METHOD PROPOSED IS BASED ON DIFFERENTIAL… more
Abstract:THE GOAL OF THE PROGRAM IS TO DEVELOP A DEVICE FOR MYOCARDIAL ABLATION USING MICROWAVE HEATING. THE DEVICE, CONSISTING OF A MICROPROCESSOR-CONTROLLED SOLID-STATE MICROWAVE ENERGY SOURCE AT 915 MHZ, CAN DELIVER LOCALIZED HEATING OF TISSUE TO CREATE ABLATION WITH A SMALL TRANSDUCER OR ANTENNA. THE… more
Abstract:COMPOSITE MATERIALS ARE GAINING WIDER ACCEPTANCE IN BOTH HIGH PERFORMANCE USES SUCH AS DEFENSE/AEROSPACE HARDWARE AND COMMERCIAL, LOW COST USES SUCH AS AUTOMOTIVE, MARINE, AND SPORTING GOODS PRODUCTS. THE COMMERCIAL SECTOR USES OF COMPOSITES REQUIRE LOW COST CONSTITUENTS AND RAPID PROCESSING. THE… more
Abstract:ONE KEY PROBLEM IN MAKING LOW ABSORBANCE MEASUREMENTS IS THERANDOM NOISE GENERATED IN VARIOUS SYSTEM COMPONENTS SUCH AS PHOTODETECTORS, ETC. ANOTHER CLASS OF PROBLEMS ARE ENVIRONMENTAL IN ORIGIN, SUCH AS AIRBORNE OR SAMPLE-BORNE CONTAMINATION, AND SCHLIEREN EFFECTS. THE PROPOSED INSTRUMENT, BASED ON… 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.
