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 ...

BIR PROPOSES AN INNOVATIVE PORTABLE X-RAY DETECTION AND MEASUREMENT SYSTEM FOR NDE APPLICATIONS. BASED ON A FILMLESS CASSETTE OF DISCRETE DIGITAL X-RAY DECECTORS, SUCH A SYSTEM WOULD ENABLE DIRECT DIGITAL IMAGING FOR VIEWING, VCR RECORDING, OR FOR COMPUTER ANALYSIS. THE SYSTEM WOULD RESEMBLE A FILM CASSETTE IN ITS PORTABILITY AND IMAGE SENSITIVITY AND RESOLUTION. WE PROPOSE TO CAREFULLY EVALUATE T ...

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 ...

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 ...

NUMEROUS AIRCRAFT ACCIDENTS HAVE OCCURED DURING TAKEOFF AND LANDING DUE TO THE STRONG AND UNEXPECTED WINDS DIVERGING FROM A MICROBURST OUTFLOW. EXTENSIVE RESEARCH HAS INDICATEDTHAT IT IS POSSIBLE TO DETECT SUCH WINDS BY MEANS OF A DOPPLER WEATHER RADAR. A LOGICAL RADAR CANDIDATE IS THE UNIT CARRIED BY ALL AIR TRANSPORTS. A PROBLEM WITH THE USE OF SUCH INSTALLED RADARS IS THEIR LOWPRF (PULSE REPETI ...

AS NASA EXPANDS ITS SPACE CONSTRUCTION AND SATELLITE SERVICING ACTIVITIES, THE NEED FOR MACHINES THAT CAN PERFORM HUMAN MANIPULATION WITHOUT THE ACTUAL PRESENCE OF ANASTRONAUT WILL BECOME NECESSARY. A RANGE OF MANIPULATION TASKS HAVE BEEN ACCOMPLISHED ON EARTH WITH THE USE OF TELEOPERATED MANIPULATORS. THESE MANIPULATORS HAVE BEEN USED FOR MANY YEARS TO ACCOMPLISH COMPLEX TWO ARMED MANIPULATION TA ...
