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 ...

DESIGN, SIMULATION, FABRICATION, AND EVALUATION OF A PROTOTYPE VERY LARGE SCALE INTEGRATION (VLSI) DATA ACQUISITION SUBSYSTEM IS PROPOSED. AVAILABLE STATE-OF-THE-ART ONE MICRON CMOS TECHNOLOGY MAY ALLOW INCORPORATION OF MORE THAN 128 CHANNELS OF 24-BIT 300 MHZ COUNTERS INTO A SINGLE INTEGRATED CIRCUIT. A PROTOTYPE SYSTEM OF SIMPLE REPEATED CELLS OF COUNTERS, CONTROL AND I/O BUFFERS HAS BEEN DESIGN ...

Intelligent Tutoring Systems (ITSs) functions as virtual tutors that adapt to student responses. Such ITSs, however, do not yield student learning improvements equivalent to students tutored by human instructors. Ascertaining Un-Reported Affect (AURA) is a closed-loop, platform-independent"front-end"for informing ITSs with near real-time inferences of student engagement and affect during learning ...

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 ...

This proposal investigates methods for graphene synthesis on Si (001) orientated substrates to enable high-volume production of graphene transistors and circuits. The proposed approach to generate a surface with the proper symmetry for graphene epitaxy is to deposit symmetry transformation layers (STL) of hexagonal-symmetry materials onto Si (001) substrates that will either facilitate the direct ...

Tactical Counter-insurgency (COIN), counter-terrorism, and anti-piracy operations require a combination of human and machine-based ISR collections to be accelerated through the Processing, Exploitation, and Dissemination (PED) processes to support rapid kill chain. GeoTRAC (Geolocation and Tactical Reconnaissance Application for COIN) will demonstrate a handheld warfighter application enabling u ...

Tactical counter-insurgency (COIN), counter-terrorism, and anti-piracy operations require a combination of human and machine-based ISR collections to be accelerated through the Processing, Exploitation, and Dissemination (PED) processes of small units. Lightweight mobile communication and computing devices together with highly portable ground-based and small UAS sensors are rapidly enabling new CO ...

In this program, Omega Optics and the University of Texas at Austin propose to develop a cost effective UV imprinting technology using high quality metallic mold by directly electroplating nickel over photoresist patterns on transparent quartz substrate. Unlike any existing nano-imprinting technology which requires ion etching to transfer patterns into substrate, we can directly replicate template ...

Several concerns currently inflate the time and cost of integrating heterogeneous data resources and impose a barrier to superior knowledge of the urban battle-space. Mashalator semi-automatically integrates heterogeneous battlefield information sources for the urban war-fighter and enables the execution of coherent queries over the integrated sources. Mashalator Phase II will leverage civilian-fa ...
