N/A

MEASUREMENT OF VELOCITY FIELDS AND FLOW RATES IS OF PRIME IMPORTANCE IN MANY AREAS OF INDUSTRY AND FLUID DYNAMICS RESEARCH. THE RESEARCH PROPOSED HEREIN WOULD RESULT IN A NONINTRUSIVE MEANS OF DETERMINING THE MAGNITUDE AND DIRECTION OF VELOCITY AND THE CORRESPONDING FLOW RATES BY THE USE OF LASER TOMOGRAPHY. LASER TOMOGRAPHY MAKES USE OF THE FACT THAT, FOR PROPERLY TUNED LASERS, THE DECAY OF LASER ...

STANDARD MONTE CARLO AND FN METHODS FOR RADIATION TRANSPORT WILL BE USED TO STUDY A NEWLY PROPOSED SHIELD CONFIGURATION FOR PROTECTION AGAINST PARALLEL OR SLIGHTLY DIVERING GAMA RAY BEAMS IN A SPACE (NON-SCATTTERING) ENVIRONMENT. THE NEW CONFIGURATION EMPLOYS LAYERED SHIELDS, WITH CONSIDERABLE SEPARATION BETWEEN THE LAYERS, TO SHADOW THE TARGET, OF THE ASSUMPTION THAT THE DIRECTION OF INCIDENCE IS ...

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 ...

THIS GRANT AWARD IS FOR THE DEVELOPMENT OF A NON-INVASIVE BEDSIDE MONITOR OF PULMONARY ARTERIAL PRESSURE IN INFANTS. THE PRINCIPLE OF OPERATION IS DERIVED FROM EARLIER NON-INVASIVE RESEARCH ON HUMANS AND FROM INVASIVE STUDIES ON DOGS, IN WHICH AN IMPROVED METHOD OF NON-INVASIVE DETECTION OF THE TIME OF CLOSURE OF THE AORTIC AND PULMONARYVALVES HAS BEEN DEVELOPED. THE TECHNIQUE DEPENDS ON THE DETEC ...
