THE PERFORMANCE OF LARGE-SCALE, LIGHTWEIGHT, SPACE-BASED MANIPULATORS IS CURRENTLY LIMITED BY THE AVAILABLE CONTROL SYSTEM TECHNOLOGIES. TO ACHIEVE HIGH PERFORMANCE WITH A SPACE-BASED MANIPULATOR, A CONTROL SYSTEM IS REQUIRED WHICH DOES NOT UNDERGO PERFORMANCE DEGRADATION DUE TO MANIPULATOR LINK FLEXURE. RESEARCH AND DEVELOPMENT IN THE AREA OF COMPLIANT MANIPULATOR CONTROL HAS BEEN HINDERED BY TWO ...

RESEARCH ON SEPARATION AND CONCENTRATION OF LUNAR DERIVED MATERIALS IS PROPOSED BASED ON ADVANCED ENERGY DYNAMICS' STATE OF THE ART EXPERIENCE IN DRY ELECTROSTATIC SEPARATION.THE TECHNICAL FEASIBILITY OF SEPARATING THESE MATERIALS INTO A VARIETY OF CHEMICALLY DISTINCT FRACTIONS USING A NOVEL COUNTERCURRENT ELECTROSTATIC PROCESS WILL BE INVESTIGATED. THE ELECTROSTATIC SEPARATOR TO BE USED IS IDEALL ...

CONVENTIONAL FILM PROCESSING TECHNIQUES ARE NOT DESIGNED FOR USE IN LOW-GRAVITY ENVIRONMENTS, BECAUSE OF THE DIFFICULTIES ASSOCIATED WITH CONFINING FREE LIQUIDS WHILE PERMITTING THE INTRODUCTION AND TRANSPORT OF ROLL FILMS INTO AND THROUGH THESE LIQUIDS. IN THIS TECHNIQUE, VISCOUS PROCESSING SOLUTIONS ARE EXTRUDED IN THIN LAYERS ONTO THE FILMS EMULSION SURFACE AND RAPIDLY PROCESS THE FILM. ARCHIVA ...

THE PURPOSE OF THIS PROPOSAL IS TO DESIGN, CONSTRUCT AND TEST A LABORATORY VERSION OF A PASSIVE CHLOROPHYLL FLUORESCENCE SENSOR SUITABLE FOR MONITORING LARGE AREAS OF VEGETATION (> 1 M2). THE LINE DISCRIMINATOR METHOD WE PROPOSE EXPLOITS A COINCIDENCE BETWEEN AN ABSORPTION LINE OFATMOSPHERIC OXYGEN AND THE R1 LINE OF A COOLED RUBY CRYSTAL,BOTH OF WHICH LIE NEAR THE PEAK OF THE CHLOROPHYLL FLUORESC ...

Alphatech will develop & demo multirsolution statistical methods for the fusion of terrain elevation from existing 3-D terrain models and new elevation data. This fusion will produce new estimates of terrain elevation with accuracies, robustness, and update ratesprviously unachievable.

ROBOTICS IS BECOMING AN INCREASINGLY IMPORTANT FIELD IN RESEARCH AND MANUFACTURING. MOST ROBOTS, HOWEVER, EITHER PERFORM REPETITIVE PREPROGRAMMED OPERATIONS OR ARE GUIDED BY A HUMAN OPERATOR. THIS IS NOT PRACTICAL IN MANY APPLICATIONS WHERE AUTONOMOUS OPERATION IS REQUIRED, AND THE MOST IMPORTANT IMPROVEMENTS IN FUTURE GENERATIONS OF ROBOTS, ESPECIALLY FOR SPACE APPLICATIONS, WILL COME IN THE AREA ...
