N/A

WITH RECENT ADVANCES IN ROBOTICS AND THE CONTINUING DEVELOPMENT OF MICROPROCESSOR-CONTROLLED SERVO-MECHANISMS, TELEOPERATED SYSTEMS ARE BECOMING INCREASINGLY FEASIBLE FOR APPLICATIONS IN OUTER SPACE. ONE OF THE MORE ADVANCED INTERFACE DEVICES EMPLOYED FOR EFFECTIVE TELEOPERATOR CONTROL IS A 3-D IMAGING AND VIEWING SYSTEM WHICH PROJECTS SLIGHTLY DISPARATE VIDEO IMAGES WITH DEPTH CUES TO AN OPERATOR ...

N/A

"THE GROWING PERIL OF SPACE DEBRIS" IS RECEIVING PUBLIC ATTENTION. IT IS BECOMING A HAZARD TO THE MILITARY AND CIVILIAN USE OF SPACE, REQUIRING INTERNATIONAL COOPERATION. YET, IT IS STILL A LITTLE UNDERSTOOD PHENOMENON, DUE IN LARGE PART TO A LACK OF ADEQUATE MONITORING INSTRUMENTATION.THIS PROGRAM IS TO STUDY THE FEASIBILITY OF THE FOLLOWING CRITICAL APPROACHES TO A LOW-COST SPACECRAFT-MOUNTABLE, ...

N/A

THIS PROJECT CONCERNS A UNIQUE APPROACH TO THE PRODUCTION OFHIGH ENERGY PRODUCT MAGNETS EMPLOYING RAPID SOLIDIFICATION METHODS. RIBBONS OF RARE EARTH-COBALT ALLOYS ARE RAPIDLY SOLIDIFIED TO PRODUCE A MICRON-SIZED COLUMNAR MICROSTRUCTUREAND THE COERCIVE FORCE DURING MAGNETIZATION IS CONTROLLED BY DOMAIN NUCLEATION MECHANISM. THIS EFFORT PRODUCES HIGH- CURIE-POINT, HIGH-ENERGY-PRODUCT PERMANENT MAGN ...

N/A

PRESSURE INSTRUMENTED AIRFOIL MODELS FOR TESTING IN CRYOGENIC WIND TUNNELS DEMAND THE SIMULTANEOUS ACHIEVEMENT OF MANY FACTORS INCLUDING STRENGTH, TOUGHNESS, DIMENSIONAL STABILITY, MACHINABILITY, BONDABILITY, ACCURACY OF PROFILE AND SURFACE FINISH. MANY PREVIOUS MODELS HAVE FAILED TO REACH COMPLETION OR HAVE PERFORMED INADEQUATELY BECAUSE ACHIEVEMENT OF SOME FACTORS HAS CRITICALLY COMPROMISED OTHE ...

IT IS WIDELY RECOGNIZED THAT BEHAVIORAL MEASURES OF WORKLOADARE INADEQUATE. EVENT-RELATED POTENTIALS (ERPS) RECORDED FROM THE HUMAN SCALP ARE A PROMISING ALTERNATIVE IN THAT THEY HAVE BEEN SHOWN TO REFLECT SELECTIVE ATTENTION, EXPECTANCIES, AND DECISION-MAKING PROCESSES. MOST PREVIOUS ERP STUDIES OF WORKLOAD HAVE BURDENED THE SUBJECT WITH A CONTRIVED SECONDARY TASK. THE PRESENT STUDY, BY TAKING AC ...

POLAR GRAPHIC DISPLAYS PRESENT QUANTITATIVE INFORMATION ABOUT A SYSTEM'S PARAMETERS AT THE NODES OF A GEOMETRIC FIGURE. BY TAKING ADVANTAGE OF HUMAN PATTERN RECOGNITION CAPABILITIES, THIS DISPLAY CONCEPT MAY ENHANCE OPERATOR'S ABILITY TO RAPIDLY ASSESS SYSTEM STATUS. THE PRESENT RESEARCH ADDRESSES BASIC AND APPLIED ISSUES IN HUMAN VISUAL PROCESSING AND DECISION-MAKING WITH POLAR GRAPHICS, IN AN EF ...
