  1. HUMAN FACTORS FOR SPACE CREWS "FUNCTION ALLOCATION DECISION AID"

    SBC: CARLOW INTERNATIONAL, INC.            Topic: N/A

    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 ...

  2. COMMUNICATIONS FOR DISTRIBUTED AND CONCURRENT PROCESSING ON MICROCOMPUTERS

    SBC: Digital Analysis Corp.            Topic: N/A

    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 ...

  3. DETERMINATION OF ORBITING SPACECRAFT ANTENNA DISTORTION BY GROUND-BASED MEASUREMENTS

    SBC: Interferometrics, Inc.            Topic: N/A

    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 ...

  7. DEVELOPMENT OF GENERALIZED COMMUNICATIONS MODELS BY COMPOSITION FROM MODULES

    SBC: Pritsker Corp.            Topic: N/A

    ONE PROMISING APPROACH TO THE DEVELOPMENT OF GENERALIZED MODELS OF COMMUNICATION SYSTEMS IS COMPOSITION OF MODELS FROM COMPONENT MODEL MODULES. IN THIS APPROACH, MODELS OF INDIVIDUAL SYSTEM COMPONENTS ARE DEVELOPED AND SUBSEQUENTLY LINKED INTO A MODEL BY MODEL COMPOSITION SOFTWARE. AN INTEGRATED SOFTWARE ENVIRONMENT SUPPORTS THIS TECHNOLOGY BY MANAGING A MODELBASE OF MODEL MODULES PROVIDING FOR TH ...

  8. THREE-DIMENSIONAL ELECTROPHORESIS CODE

    SBC: Roberts Assoc Inc.            Topic: N/A

    WE PROPOSE TO DEVELOP A FLEXIBLE EFFICIENT COMPUTER CODE TO SIMULATE ELECTROPHORETIC SEPARATION PHENOMENA IN UP TO THREESPATIAL DIMENSIONS. THE CODE WILL ALLOW EITHER A CYLINDRICAL OR A RECTANGULAR GEOMETRY, AND WILL COMPUTE THE TIME EVOLUTION OF THE CONCENTRATIONS OF AN ARBITRARY NUMBER OF CHEMICAL SPECIES, AND OF THE TEMPERATURE. THE PH DISTRIBUTION, CONDUCTIVITY, ELECTRIC FIELD, AND FLUID MOTIO ...

  9. ANALYSIS OF FLOWFIELDS AROUND HYPERVELOCITY VEHICLES IN LOW-TO-HIGH DENSITY FLIGHT REGIME

    SBC: VIGYAN, INC.            Topic: N/A

    THE HYPERSONIC VEHICLES FLYING AT HIGH ALTITUDES OPERATE IN A FLOW REGIME WHERE THE NONCONTINUUM EFFECTS NEAR THE SURFACE AND FINITE SHOCK THICKNESS DUE TO LOW DENSITY MAKE THE CONVENTIONAL CONTINUUM TECHNIQUES GROSSLY INADEQUATE. CHEMICAL NONEQUILIBRIUM IS ALSO IMPORTANT UNDER THE LOW-DENSITY FLOW CONDITIONS. UNTIL RECENTLY NOT MUCH WORK HAS BEEN DONE TO EVALUATE DEFICIENCIES OF THE EXISTING CONT ...

  10. INVESTIGATION OF WEIS-FOGH PRINCIPLE OF HIGH LIFT AS APPLIEDTO TURBOMACHINERY FLOWS

    SBC: VIGYAN, INC.            Topic: N/A

    THE PROPOSED RESEARCH IS DIRECTED TOWARDS A DETAILED ANALYTICAL AND NUMERICAL STUDY OF THE UNSTEADY VORTEX MOTIONIN THE CLAP-FLING MOTION, OBSERVED BY WEIS-FOGY, WHICH COULDYIELD LIFT COEFFICIENTS OF UP TO EIGHT. THE APPLICATION OF THE CLAP-FLING MOTION ANALOGY TO A COMPRESSOR STAGE COULD, UNDER CERTAIN CIRCUMSTANCES, PREDICT A STRONG ROTOR-STATOR INTERACTION WHICH COULD YIELD AN IMPROVED STAGE PE ...
