CURRENT ACTIVITY WITHIN THE NRC AND THE NUCLEAR INDUSTRY SEEKS TO EXPLOIT THE BENEFITS OF PRA IN RISK-BASED APPROACHES TO RELIEVE REGULATORY BURDEN ON THE ECONOMICALLY THREATENED NUCLEAR POWER PLANTS. THE ACCIDENT PREVENTION GROUP HAS BEEN DEVELOPING THE CONCEPT OF AN INTEGRATED RISK MANAGEMENT PROGRAM (IRMP) TOWARD SUCH GOALS. A KEY ELEMENT OF AN IRMP IS AN "OPERATIONAL RISK MODEL" OF THE NPP THA ...

AN SBIR PROJECT IS PROPOSED HERE TO DEVELOP NOVEL TECHNIQUES FOR DIRECTIVE/RETRODIRECTIVE COMMUNICATIONS, BY USING BLIND ADAPTATION ALGORITHMS TO ADJUST THE ARRAY WEIGHT ON THE RECEIVE/TRANSMIT PATHS OF A COMMUNICATION SYSTEM. THE PROPOSED PROCESSOR HAS THE CAPABILITY TO AUTOMATICALLY EXTRACT SIGNALS FROMTHE RECEIVED ENVIRONMENT, AND TO TRANSMIT SIGNALS BACK TO THE SIGNAL SOURCE USING AN ANTENNA P ...

RESEARCH INTO VISUALIZATION TECHNIQUES FOR HEURISTIC PROCESSES IS PROPOSED, INCLUDING THE DESIGN OF A SOFTWARE SYSTEM IN WHICH THESE TECHNIQUES ARE IMPLEMENTED. IN ADDITION TO THE SOFTWARE ARCHITECTURE,THE SYSTEM DESIGN WILL INCLUDE A DESCRIPTION OF USER INTERFACE FUNCTIONS AND A STRATEGY FOR INTERFACING WITH EXISTING ARTIFICIAL INTELLIGENCE APPLICATIONS. EXISTING WORK IN ALGORITHM ANIMATION AND I ...

ADS PROPOSES TO ADAPT AND APPLY CHANGE DETECTION PROCESURES DEVELOPED FOR THE NATIONAL INTELLIGENCE COMMUNITY TO THE PROBLEM OF SUPPORT FOR THE BATTLEFIELD COMMANDER. WE WILL BE WORKING WITH BOTH OF THE DOMINANT CHANGE DETECTION PARADIGMS WITH BOTH PIXEL LEVEL AND SYMBOLIC CHANGE DETECTION AND DETERMINING WHICH OF THE TWO OR POSSIBLE HYBRIDIZATION WILL PROVIDE THE BEST SHORT TERM CHANGE DETECTION.

A MULTI-DIMENSIONAL NUMERICAL MODEL FOR PREDICTING CLOUD COVER, FOG, AND HAZE UNDER BATTLEFIELD CONDITIONS IS DEVELOPED. THE PROGRAM UTILIZES REAL TIME METEOROLOGICAL DATA (WHEN AVAILABLE) TO PREDICT METEOROLOGICAL CONDITIONS OVER IRREGULAR TERRAIN. THE COMPUTER PROGRAM IS RELATIVELY SIMPLE AND EXECUTES QUICKLY ON A VARIETY OF COMPUTER SYSTEMS. PROBLEMS REQUIRING SEVERAL THOUSAND NODES CAN BE SOLV ...

Complex Helicopter Analysis codes, such as the SEcond Generation Comprehensive Analysis System (2GCHAS), have been developed toprovide a common framework for interdisciplinary design and analysis of rotorcraft systems. A major limitation on the effectiveness of the second generation comprehensive analysis codes is the slow processing speed that results from the computational intensity of the analy ...
