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 Phase 2 project targets the completion of the development of an improved system for the broadcasting of the WWVB signal, as a direct continuation of the Phase 1 project, which successfully validated the proposed approach through a feasibility study and analyses. Objectives of this project include the design of the new modulation scheme and protocol, the development of a new time-code generato ...

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 ...

In this project, we will design a standard-based, robust, and efficient iris image quality measure tool. It can be used to select the images of sufficient quality for inclusion in the biometric repository database(s), improve collection processes, and develop quality-based iris matching algorithms. At the same time, it can be incorporated into iris recognition systems as plug-ins to improve recogn ...

Nanometrology International, Inc. (NMI) proposes to demonstrate the feasibility of 3-dimensional (3D) characterization of nanoscale objects using scanning probe microscopy (SPM) with a measurement uncertainty of less than 0.7 nm. To accomplish this task, we propose a novel method of 3D tip characterization and use of an innovative surface reconstruction algorithm recently introduced by NIST and th ...

The recent discovery of Eu activated alkali-earth halide scintillators promises to revolutionize remote detection and identification of radioisotopes. This proposal addresses the development of methods for production of large-volume, high-quality Barium Bromine Iodide scintillators. High-quality, low-cost scintillators for detection of gamma-rays are needed for monitoring of nuclear non-proliferat ...

Iris biometrics offers the potential for highly accurate identity verification. However, over 25 million people in the United States and over 125 million people worldwide wear contact lenses, and it would be impractical to require users to remove their contact lenses for recognition purposes. As a result, developing methods to measure and mitigate any degradation associated with contact lenses and ...

The detection of neutrons is a critical capability for homeland security applications. Helium-3- based proportional counters are commonly employed; however, the supply of He-3 is insufficient to meet the demand. A replacement for He-3 detectors should efficiently detect neutrons in a gamma-ray background and be commercially available at prices equivalent to comparable detectors prior to the He-3 s ...
