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 ...

NASA IS CONTINUALLY DEVELOPING NEW SYSTEMS RANGING FROM COMPUTER SOFTWARE TO TEST FACILITIES TO LARGE SPACECRAFT. EACH SYSTEM DEVELOPMENT IS INITIATED AND CONTROLLED THROUGH THE USE OF REQUIREMENTS SPECIFICATIONS. THE PROPOSED STUDY WILL DETERMINE THE FEASIBILITY OF DEVELOPING AN AUTOMATED TECHNICAL DOCUMENTATION SYSTEM FOR A DESK TOP COMPUTER. THE SYSTEM WILL BE PROTOTYPED TO DEVELOP AND TEST CON ...

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 ...

SUPER ACCURATE ADAPTIVE COMPUTATIONAL SCHEMES FOR THE ANALYSIS OF FLUID STRUCTURE INTERACTION AND COMPLEX THREE-DIMENSIONAL INTERNAL FLOWS ARE TO BE DEVELOPED. NEW PETROV-GALERKIN FINITE ELEMENT METHODS FOR SOLVING THE NAVIER-STOKES EQUATIONS. COUPLED WITH THE EQUATIONS OF MOTION OF ELASTIC DUCTS AND MANIFOLDS, ARE TO BE DEVELOPED AND USED TO SIMULATE FLOWS IN AEROSPACE PROPULSION SYSTEMS (SUCH AS ...

ENTECH IS PLEASED TO PROPOSE TO NASA THE DEVELOPMENT OF AN INNOVATIVE CROSSED LENS GALLIUM ARSENIDE PHOTOVOLTAIC CONCENTRATOR, CAPABLE OF PROVIDING AN OPERATIONAL EFFICIENCYOF 22% IN THE SPACE ENVIRONMENT. THE PROPOSED SYSTEM WILL UTILIZE THREE STATE-OF-THE-ART DEVELOPMENTS: (I) A CYLINDRICAL LENS/FRESNEL LENS CROSSED-COUPLED OPTICAL CONCENTRATOR WHICH WILL PROVIDE 96% OPTICAL EFFICIENCY AT 100-20 ...

"DARK FOCUS" IS DEFINED AS THE RESTING STATE OF VISUAL ACCOMMODATION YET TWO GENERAL MISCONCEPTIONS EXIST. FIRST, THAT THE RESTING POINT IS AT OPTICAL INFINITY, AND SECONDLY,THAT THE EYE ACCOMMODATES ACCURATELY. VISUAL PERFORMANCES REQUIRED IN SPACE ENTAIL CONTINUOUSLY CHANGING VIEWING DISTANCES AND TO ALLOW CREW MEMBERS TO PERFORM ROUTINELY ACCOMMODATION CHANGES NEED TO BE ASSESSED. WHEN A PERSON ...

LACK OF NON-GEOMETRIC KNOWLEDGE IS IDENTIFIED AS A FUNDAMENTAL FLAW OF THE MODELERS UPON WHICH MOST TRADITIONAL THREE-DIMENSIONAL COMPUTER-AIDED DESIGN (CAD) SYSTEMS ARE FOUNDED. A HYBRID REPRESENTATION SCHEME IS OUTLINED WHICH ADDS NON-GEOMETRIC SEMANTICS TO THE TRADITIONAL MODELING METHODS TO FORM A KNOWLEDGE BASE (K-BASE). THE K-BASE SYSTEM OUTLINED BORROWS CONCEPTS FROM ARTIFICIAL INTELLIGENCE ...

A LABORATORY KIT WILL BE DEVELOPED FOR THE RAPID DIAGNOSIS OF BACTERIAL INFECTIOUS DISEASES UNDER MICROGRAVITY CONDITIONS. THE KIT WILL CONSIST OF COAGGLUTINATION AND/OR LATEX AGGLUTINATION REAGENTS AND ENRICHMENT BROTHS FOR THE RAPID, SELECTIVE GROWTH OF SPECIFIC BACTERIAL PATHOGENS. THE PHASE I EFFORT WILL BE DIRECTED TOWARD PRODUCING A FUNCTIONAL, EXPERIMENTAL KIT. COAGGLUTINATION AND/OR LATEX ...
