DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

THIS PHASE I EFFORT WILL APPLY THEORETICAL METHODS BASED PRINCIPALLY ON CAGNIARD'S FORMALISM (PREVIOUSLY INCORPORATED BY US INTO OUR POWERFUL SWREF CODE), TO THE PROPAGATION AND FOCUSING, IN BOTH REFLECTIVE AND PHASED-ARRAY EQUIPMENT, OF SHOCK-WAVES PRODUCED BY UNDERWATER SPARKS. THE OBJECTIVE IS TO INVESTIGATE AND PROVIDE DESIGN DATA FOR LITHOTRIPSY EQUIPMENT IN WHICH FOCUSED SHOCK WAVES ARE USED ...

THE SERVICEABILITY LIMIT STATE ASSOCIATED WITH OCCUPANT COMFORT UNDER WIND INDUCED LATERAL AND TORSIONAL MOTION IS BECOMING AN INCREASINGLY IMPORTANT CONSIDERATION IN THE DESIGN OF TALL BUILDINGS. IN SOME INSTANCES, STRUCTURAL MODIFICATIONS REQUIRED TO PRODUCE ACCEPTABLE PREDICTED RESPONSE CHARACTERISTICS CAN COST HUNDREDS OF THOUSANDS OF DOLLARS OR EVEN MILLIONS OF DOLLARS. WITH THESE KINDS OF CO ...

RESEARCH AND DEVELOPMENT WILL BE CARRIED OUT TO PROVIDE PROTOTYPE, ACTIVELY CONTROLLED GAS BEARINGS FOR PRECISION MOVEMENT IN INSTRUMENTS AND MACHINE TOOLS. THIS WILL DRAW UPON PRELIMINARY WORK ON (1) FABRICATION, (2) DYNAMIC ANALYSIS OF THE BEARING AND SUPPORTED MASS, (3) PIEZOELECTRIC VALVING AND PIEZOELECTRIC DISPLACEMENT OF THE BEARING SURFACE, AND (4) THE ADAPTATION OF A MICROPROCESSOR TO SER ...

This Small Business Innovation Research (SBIR) Phase II project will develop a new class of in-fiber chiral polarizers based upon chiral fiber gratings. A double helix variation of the effective refractive index will be formed by twisting fibers with a noncircular core as they pass through a miniature oven. These chiral fiber polarizers will be created from specially prepared glass performs in a l ...

This Small Business Innovation Research (SBIR)Phase I project will address the feasibility of producing low attenuation, ultrahigh bandwidth perfluorinated polymer optical fibers (POF) by a low-cost continuous extrusion process. Currently, there is an unmet need for a very simple, easy to use optical medium for multi-Gb/s networks in applications such as hospital systems, educational institutions, ...

UNITED STATES SEMI-TRAILER VANS EXPEND OVER 10,000,000,000 GALLONS OF DIESEL FUEL PER YEAR MOVING AIR AROUND THE VEHICLES. THIS NEEDLESS WASTE OF FUEL INCREASES OUR IMPORT OIL DEPENDENCY, AS WELL AS ADDS NEEDLESS DIESEL EXHAUST CARCINOGENS INTO OUR ATMOSPHERE. RECENTLY, CONGRESS HAS ENACTED LEGISLATION WHICH PERMITS TRACTOR/SEMI-TRAILER LENGTH LIMITS TO BE EXCEEDED IF THE PURPOSE IS TO IMPROVE FUE ...

THE COLLAPSE OF A STEAM BUBBLE IN A POOL OF SUBCOOLED WATER IS KNOWN TO RESULT IN THE RADIATION OF PRESSURE WAVES OF ENORMOUS MAGNITUDE. THESE PRESSURE WAVES CAN BE USED TO FRACTURE MATERIALS AND/OR REMOVE MATERIAL IF THEY CAN BE DIRECTED. DEVELOPMENT OF A NOZZLE IS PROPOSED WHICH WILL DIRECT COLLAPSING STEAM BUBBLES TOWARDS A SURFACE AND SET UP STRESS WAVES IN THE SOLID WHICH WILL RESULT IN SURFA ...

This Small Business Innovation Research (SBIR) Phase II project will produce a prototype low-rate fluid flow instrument for nuclear power plants that incorporates several novel features that permit its use as a clamp-on measurement device having minimal installation costs and complications. By utilizing waste heat on piping lines, and wireless data links, the flow sensor system avoids the require ...

This Small Business Innovation Research (SBIR) Phase I project will develop a tool to help engineering faculty design and administer assessments of engineering education. The tool will also assist in the management of assessment data to support instructional decisions for individual students, decisions on courses and programs, and accreditation decisions through the Accreditation Board for Engine ...
