A DIRECT TRANSFORMATION FROM IMAGE COORDINATES TO ROBOT JOINT COORDINATES WILL BE DEVELOPED TO SERVE AS THE BASIS FOR A BINARY VISION SYSTEM FOR SIX DEGREE OF FREEDOM ROBOT CONTROL. A SYSTEM IDENTIFICATION ALGORITHM WILL ENABLE THE SYSTEM TO BE USED AS A TURN-KEY SYSTEM WITH ANY ROBOT WHICH ACCEPTS JOINT COORDINATE INPUT. THE DIRECT TRANSFORMATION FROM IMAGE SPACE TO ROBOT JOINT SPACE WILL BE ACCO ...

SAFETY SYSTEM TEMPERATURE SENSORS IN NUCLEAR POWER PLANTS ARE SUBJECT TO PERFORMANCE DEGRATION BECAISE PF AGING EFFECTS. A PROGRAM OF LABORATORY TESTING AND IN-SITU TESTINGIS NEEDED TO ENSURE THAT AGING DOES NOT LEAD TO REDUCED SAFETY AND AVAILABILITY. MUCH OF THE TECHNOLOGY NEEDED FOR THIS PROGRAM NOW EXISTS AS ISOLATED METHODS AND PROCEDURES. THESE WILL BE USED IN THIS PROJECT TO PERFORM AN AGIN ...

THIS PROJECT WILL PRODUCE A DECISION AID TO ASSIST SYSTEM DESIGNERS AND MISSION PLANNERS IN THE ALLOCATION OF SYSTEM FUNCTIONS TO HUMAN PERFORMANCE OR TO SOME DEGREE AUTOMATION. THE DECISION AID IS MADE UP OF: 1. A DATA BASE AND DATA CLASSIFICATION SCHEME; 2. AN EXPERT SYSTEM TO: A) INTEGRATE AND PRIORITIZE REQUIREMENTS DATA THAT WILL INFLUENCE THE ALLOCATION DECISION, B) ACTUALLY MAKE THE DECISIO ...

THIS PROPOSAL DESCRIBES A PROJECT TO DEVELOP AND EXAMINE A CFD NUMERICAL SOLUTION ALGORITHM FOR THE THREE-DIMENSIONAL EULER/NAVIER-STOKES EQUATIONS THAT DOES NOT RELY ON A WELL-STRUCTURED, BODY-FITTED COORDINATE SYSTEM FOR ROBUSTNESS. THE SPECIFIC APPLICATION IS FOR REALISTIC CONFIGURATION AERODYNAMICS ANALYSIS OF HIGH SPEED MIXED SUPERSONIC FLOWS AT LARGE REYNOLDS NUMBER. A THEORETICAL ANALYSIS F ...

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP THE DESIGN AND APILOT IMPLEMENTATION OF TWO COMMUNICATIONS PACKAGES WHICH WILL SUPPORT DISTRIBUTED COMPUTING FROM A MICROCOMPUTER WORKSTATION BASE. PARTICLULAR EMPHASIS IS GIVEN TO THE PROBLEM OF DIAL-UP ACCESS TO COMMUNICATION NETWORKS IN THE CONTEXT OF DISTRIBUTED DATA BASE MANAGEMENT SYSTEMS. THE FIRST PACKAGE ADDRESSES THE PROBLEM OF SIMULTANEOUSLY R ...

WE PROPOSE TO STUDY A GROUND-BASED SYSTEM FOR MEASURING THE DISTORTIONS AND POWER DISTRIBUTIONS OF IN-ORBIT REFLECTOR ANTENNAS AND PHASED ARRAYS. THE SYSTEM WILL MEASURE THE FAR-FIELD AMPLITUDES AND PHASES IN THE MAIN BEAM AND SIDELOBES OF THE SATELLITE ANTENNA. THE FOURIER TRANSFORM OF THESE DATA GIVES THE COMPLEX APERTURE DISTRIBUTION. PHASE DEVIATIONS IN THE APERTURE DISTRIBUTION ARE RELATED TO ...

RECENT TECHNICAL ADVANCEMENTS IN THE SEMICONDUCTOR DEVICE AND POWER CONDITIONING TECHNOLOGIES HAVE LED TO SUBSTANTIAL IMPROVEMENTS IN TERMS OF SIZE, WEIGHT, EFFICIENCY AND POWER QUALITY OF THE POWER CONDITIONING EQUIPMENT WHICH IS BEING CONSIDERED FOR SPACE APPLICATIONS. WITH THESE ADVANCEMENTS COMES AN ABUNDANCE OF DESIGN CHOICES AND INCREASED DEGREES OF FREEDOM WITH RESPECT TO POWER SYSTEM CONTR ...

THE PROPOSED INNOVATION SYNTHESIZES THREE HIGH TECHNOLOGY TOOLS IN AN EFFORT TO DEVELOP A RELIABLE NUMERICAL MESOSCALEWEATHER FORECAST SYSTEM FOR USE AT THE KENNEDY SPACE CENTER FOR SHUTTLE LAUNCH AND LANDING OPERATIONS. THESE TOOLS ARE:(1) AN ADVANCED MESOSCALE NUMERICAL WEATHER PREDICTION MODEL, I.E., THE MESOSCALE ATMOSPHERIC SIMULATION SYSTEM (MASS), (2) THE CRAY-2 SUPERCOMPUTER SYSTEM, AND (3 ...
