N/A

THE PROPOSED RESEARCH IS DESIGNED TO UTILIZE ARTIFICIAL INTELLIGENCE TECHNOLOGY FOR ASSISTING USERS LOCATING AND UNDERSTANDING TECHNICAL INFORMATION IN MANUALS USED FOR PLANNING AND CONDUCTING WIND TUNNEL TESTS AND INCREASING THEEFFICIENCY OF PERSONNEL TRAINING IN WIND TUNNEL TESTING PROCEDURES. THE OBJECTIVE IS TO CREATE A COMPUTERIZED MANUAL IN THE FORM OF HYPERTEXT AND AN ADVISORY SYSTEM WHICHS ...

EFFECTIVE PREDICTION OF GLOBAL PHENOMENA REQUIRES DETAILED KNOWLEDGE OF TEMPERATURES, RAINFALL RATES, AND PARTICLE SIZEDISTRIBUTIONS. IN PARTICULAR, KNOWLEDGE OF TROPICAL RAINFALL RATES IS IMPORTANT FOR UNDERSTANDING THE MAGNITUTE OF THE EFFECT OF TROPICAL LATENT HEATING ON GLOBAL ATMOSPHERIC CIRCULATION. SATELLITE MEASUREMENTS OF TROPICALPRECIPITATION PATTERNS HAVE BEEN PROPOSED USING SENSITIVE, ...

AN INNOVATIVE INSTRUMENTED ROCKET FOR MEASURING WIND PROFILES IN SUPPORT OF AEROSPACE VEHICLE OPERATIONS IS PROPOSED. IMMEDIATE APPLICATION IS TO NASA'S STS OPERATIONSALTHOUGH MANY OTHER APPLICATIONS CAN BE IDENTIFIED. TECHNIQUES FOR MEASURING STS LAUNCH WINDS CLOSE TO THE SCHEDULED LAUNCH TIME AND LAUNCH PATH WOULD REDUCE THE UNCERTAINITY MARGIN OF CALCULATED WIND LOADS, INCREASE LAUNCH PROBABILI ...

THE 20 KHZ POWER SYSTEMS, CURRENTLY BEING CONSIDERED FOR THE SPACE STATION AND ADVANCED SPACECRAFT, DEMONSTRATE HARMONIC RESONANCES DUE TO INTERACTION BETWEEN THE SWITCHINGOF THE CONVERTERS AND THE DISTRIBUTION SYSTEM. IN SOME CASES, THE HARMONIC RESONANCE BECOMES SO SEVERE THAT IT MAY CAUSE COMPONENT DAMAGE AND ELECTROMAGNETIC INTERFERENCE. CONTROLLED SUPPRESSION OF THESE HARMONIC RESONANCE FREQU ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

A FAST-RESPONSE METHOD FOR MEASUREMENT OF MOLECULAR OXYGEN CONCENTRATIONS IN HIGH TEMPERATURE FLOWS IS NEEDED FOR WIND TUNNEL RESEARCH ON HYPERSONIC AIR-BREATHING ENGINES AS WELL AS OTHER APPLICATIONS IN COMBUSTION RESEARCH OR CONTROL. THE PROPOSED INNOVATION WILL UTILIZE INEXPENSIVE ROOM TEMPERATURE LASER DIODES TO MEASURE ABSORPTION BY OXYGEN AT NEAR-INFRARED WAVELENGTHS. THESE LASERS WILL BE US ...

N/A

THE PROPOSED PHASE I EFFORT IS AIMED AT A GENERAL AND BASIC NEED IN NASA'S FLIGHT HARDWARE FOR EXPERIMENTAL ANIMALS: TO DELIVER FOOD TO RODENTS IN SPACE IN A MANNER THAT PERMITS FOOD CONSUMPTION DATA TO BE ACCURATELY COLLECTED AND STORED. OUR APPROACH TO HARDWARE DESIGN IS INNOVATIVE. WE CONSIDER THE TEST ANIMALS TO BE PART OF THE DESIGN TEAM AND WE INCORPORATE ANIMAL TESTING THROUGHOUT CONCEPTUAL ...

AS NASA EXPANDS ITS SPACE CONSTRUCTION AND SATELLITE SERVICING ACTIVITIES, MACHINES THAT CAN PERFORM HUMAN MANIPULATION WITHOUT THE ACTUAL PRESENCE OF AN ASTRONAUT ARE BECOMING NECESSARY. ON EARTH, MANIPULATORS HAVE BEEN USED FOR YEARS TO ACCOMPLISH COMPLEX TASKS UNDER TELEOPERATORED CONTROL. TO PROVIDE ADVANCED MANIPULATION FOR SPACE, WE MUST MOVE FORWARD BY INCORPORATING THE HUMAN THOUGHT PROCES ...
