Abstract:IN AN EFFORT TO REACH HIGHER POWERS, LASER RESEARCHERS HAVE DEVELOPED LARGER AND INCREASINGLY COMPLEX DEVICES. AN ALTERNATE SCALING APPROACH IS TO COMBINE THE OUTPUT POWER OF MANY SIMPLE LOW-POWER LASERS IN AN ARRAY. MICROLASERS ARE THE PERFECT ARRAY ELEMENTS BECAUSE THEY ARE MASS-PRODUCIBLE AND… more
Abstract:Jet engine test cells are faced with meeting regulations related to NOx emissions and opacity. Based upon reported research results, it appears that the Pulse Induced Plasma Chemical Process (PPCP) could be effectively applied to jet engine test cells for the control of NOx. The process provides… more
Abstract:A STEP TOWARD BEING NUMBER ONE IN MATHEMATICS AND SCIENCE EDUCATION BY THE YEAR 2000 (AMERICA 2000 GOAL) AND MAINTAINING REASONABLE SCHOOL BUDGETS CAN BE MADE BY INTRODUCING A LOW COST SYSTEM WHICH WILL BRING THE STATE-OF-THE-ART TECHNOLOGY INTO THE HIGH SCHOOL LABORATORY. THE PLANNED LABORATORY… more
Abstract:STATIONARY SOURCES IN THE U.S. EMIT ABOUT ONE MILLION KG OF MERCURY INTO THE ATMOSPHERE ANNUALLY. MAJOR SOURCES OF THESE EMISSONS ARE FOSIL FUEL COMBUSTIONFACILITIES ANE MUNICIPAL SOLID WASTE INCINERATORS. MUCH WORK IS BEING DONE BY DOE AND INDUSTRY TO CHARACTERIZE THESE EMISSIONS AND TO DEVELOP… more
Abstract:The development of a simple, reliable, and easily operated system to detect and measure airborne lead (Pb) to trace levels is the subject of the Phase I effort. Lead is toxic to humans at very low levels and is ingested easily by breathing air in which elemental Pb or compounds of this element are… more
Abstract:IMPROVED FABRIC FILTER PERFORMANCE FOR BOTH THE COLLECTION OF FINE PARTICULATE MATTER (PARTICLES LESS THAN 10 MICRONS) AND TOXIC METAL EMISSIONS FROM FLUEGASES IS IMPORTANT BECAUSE MOST OF THE TOXIC METALS ARE CONCENTRATED IN THIS SIZE RANGE, FINE PARTICLES ARE RESPIRABLE AND THEREFORE POSE A HEALTH… more
Abstract:REMOVAL OF MERCURY FROM CONTAMINATED WATERS IS A CONTINUING NEED FOR DOE'S SITE REMEDIATION EFFORTS. SOME SURFACE AND SUBSURFACE DISCHARGE OF CONTAMINATED WATER IS CONTINUING FROM MERCURY LOST TO THE ENVIRONMENT IN THE PAST. IN THE FUTURE, IT IS ANTICIPATED THAT MERCURY-CONTAMINATED STRUCTURES AND… more
Abstract:FOSSIL FUEL COMBUSTION SOURCES ARE THE LARGEST SINGLE CONTRIBUTOR OF ATMOSPHERIC MERCURY EMISSIONS AND THE SECOND LARGEST CONTRIBUTOR OF ATMOSPHERIC SELENIUM. OF ALL THE TRACE METALS CONTAINED IN COAL, MERCURY AND SELENIUM ARE OF GREATEST CONCERN SINCE THEY ARE THE MOST VOLATILE OF THE METALS, THEY… more
Abstract:ADAPTIVE DIGITAL ARRAY PROCESSING IN AIRBORNE RADARS CAN PROVIDE A MAJOR IMPROVEMENT IN TARGET DETECTABILITY BY ADAPTIVELY SUPPRESSING CLUTTER AND JAMMING. THE EFFECTIVENESS OF THIS SPACETIME ADAPTIVE PROCESSING HAS BEEN DEMONSTRATED BY DETAILED SIMULATION AT ASI. RECENTLY, ARRAY RADAR FLIGHT TEST… more
Abstract:WE PROPOSE TO DEMONSTRATE THE FEASIBILITY OF OPTICAL CHARACTER RECOGNITION (OCR) ON A VLSI NEUROCOMPUTER. THE OCR SYSTEM WILL USE STATE OF THE ART ARTIFICIAL NEURAL NETWORK CLASSIFIERS ONADAPTIVE SOLUTIONS' CNAPS NEUROCOMPUTER CHIPS. THE CNAPS CHIPS OFFERUNPRECEDENTED PERFORMANCE OF ARTIFICIAL… more
Abstract:A smart wing design is proposed here to demonstrate the feasibility of using smart structures for suppression of aircraft vibration. Active wing research, conducted for many years, continues today as an important element in advanced aircraft technology. This program will analytically demonstrate the… more
Abstract:Recent research has shown that effective jammer and clutter suppression is best performed with fully space-time adaptive processing. However, allowing adaptive weights on every tap on every element is computationally prohibitive and requires too many samples to converge. Eigenvalue analysis shows… more
Abstract:Resin transfer modling (RTM) offers many advantages over hadn lay-up of prepreg or wet filament winding in the production of advanced composites. Successful application of RTM requires complete resin infiltration of the molded dry fiber preform. Uncertainty in the resin infiltration process due to… more
Abstract:We will develop a new fiber sensor technology based on detection of SP oscillations with thespecific goal of designing a simple, low-cost, remote optical probe capable of measuring HIV and otherviral antibodies upon direct contact with a suitable biological fluid. The sensor will be capable… more
Abstract:We will create a novel fiber-optic technique to detect the presence and monitor levels ofenvironmentally harmful gases emitted by utility companies and chemical industries as well as presentin inhabited places. Gas molecules are absorbed into a thin film whose optical properties are thenmonitored by… more
Abstract:THE OBJECTIVE OF THIS RESEARCH IS TO EXPLORE THE FEASIBILITY OF DEVELOPING A HIGH INTENSITY UV EXCIMER SOURCE FOR THE DEMANDING REQUIREMENTS OF THE SEMICONDUCTOR MANUFACTURING AND MATERIALS PROCESSING INDUSTRY. EMERGING PROCESSING TECHNOLOGIES NOT REQUIRING A COHERENT SOURCE INCLUDING UV WAFER… more
Abstract:THE OBJECTIVE OF THIS PROJECT IS TO EMPLOY THE BETATRON PRINCIPLE TO PRODUCE AN INEXPENSIVE ELECTRON ACCELERATOR CAPABLE OF PRODUCING 20-50 MEV ELECTRONS WITH GOOD BEAM QUALITY AND HIGH-AVERAGE CURRENTS OF UP TO 5-50 MUA. IN CONVENTIONAL BETATRONS WHICH HAVE BEEN IN EXISTENCE FOR OVER 50 YEARS,… 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.
