THE CONTRACTOR SHALL DEVELOP A FUZZY SET METHODOLOGY FOR UNCERTAINTY ANALYSIS IN PROBABILISTIC SEISMIC SAFETY ASSESSMENT OF NUCLEAR POWER PLANTS. FUZZY SET LOGIC WILL BEUSED FOR COLLECTING, QUANTIFYING AND PROPAGATING SUBJECTIVE,ENGINEERING JUDGEMENT USED IN THE UNCERTAINTY ANALYSIS. IN PHASE I, FEASIBILITY OF THE PROPOSED APPROACH WILL BE DEMONSTRATED BY APPLYING IT TO SELECTED PARTS OF A PROBABI ...

"This SBIR Phase I project will develop an affordable, sensitive, fast-response solution to real-time monitoring of Elemental Carbon (EC). EcoChem will employ a proven sensor technology, the photoemission aerosol sensor (PAS) to detect EC. The PAS photoionizes carbonaceous aerosols with a unique excimer lamp [Burtscher, 1992] whose wavelength is chosen to selectively ionize EX and polycyclic aro ...

AN "INHALATION SCREENING DOSE COLLAR-STANCHION MONITOR" WITHEMBEDDED MINIATURE THIN-WALL GEIGER-MUELLER RADIATION DETECTORS EVALUATES THE THYROID GLAND FOR NANOCURIE ACTIVITYINVENTORY. THE PRIMARY TECHNICAL OBJECTIVE IS TO ESTABLISH THAT THE "COLLAR-STANCHION MONITOR" WILL BE CAPABLE OF DETECTING WITHIN 15 SECONDS AND WITH 2 SIGMA CONFIDENCE AN ACTIVITY INVENTORY OF 0.7 NANOCURIES OF I-131 DOSE EQ ...

THIS PROPOSAL IS CONCERNED WITH THE ECONOMIC REMOVAL OF HYDROGEN SULFIDE, A TOXIC MATERIAL, FROM SOUR NATURAL GAS AND PETROLEUM PRODUCTS. THE CURRENT STATUS OF H2S PROCESSING IS REVIEWED. THE CHEMISTRY OF SULFUR AND SULFIDE IN AQUEOUS SOLUTIONS AND PRELIMINARY WORK ALREADY CARRIED OUT IN THE CONTINUOUS ELECTROLYSIS OF H2S TO YIELD HYDROGEN AND SULFUR ARE BRIEFLYDISCUSSED. THE ESTIMATED ECONOMIC GA ...

"The ability to determine air pollutant emission quantity and emission rate are extremely important for environmental protection, policy making, and law enforcement. A pollutant emission rate can be determined by calculating the product of the airflow rate from an exhaust fan and the composition of the pollutant in the air. The pollutant may be any number of things, including particulate matters ...

"Operational Technology Corporation (OpTech) proposes to couple the ultrasensitivity of fluorescence-based detection with the high selectivity of synthetic DNA aptamers as replacements for antibodies to detect chemical and biological (CB) terrorism threats in 10 minutes or less from a variety of swabbed surfaces and liquid matrices. OpTech has previously provided strong proof-of-concept for a rap ...

"As part of its mission to protect human health and the environment, the U.S. Environmental Protection Agency is dedicated to developing and promoting innovative cleanup strategies that restore contaminated sites to productive use, reduce associated costs, and promote environmental stewardship. However, in adopting this strategy there will be an increasing need to implement a more cost effective, ...

Storm surge poses a grave threat to both life and property as hurricanes make landfall. The ability to monitor surge in real-time using a densely-space network of sensors with integrated data recording and telemetry would provide NOAA with a unique capability. Our approach is to offer a system which incorporates a flexible multi-modal data acquisition platform with integrated telemetry for real-ti ...
