TODAY AN OVERWHELMING MAJORITY OF CFD CALCULATIONS ARE DONE WITH STANDARD FIXED GRID FINITE DIFFERENCE METHODS. HOWEVER, A SIMPLE CALCULATION CAN ESTABLISH THAT SUCH METHODS CANNOT POSSIBLY EXPLOIT THE FULL COMPUTING POWER OF TODAY'S COMPUTING EQUIPMENT NOR CAN THEY DELIVER HIGHLY ACCURATE SIMULATIONS OF FINE SCALE FLOW PHENOMENA IN COMPLEXFLOW DOMAINS. TO FULLY EXPLOIT CONTEMPORARY COMPUTING CAPA ...

THIS PROJECT WILL DEVELOP A NEURAL NETWORK IMPLEMENTATION OF AN IDENTIFICATION AND CONTROL COMPUTER FOR NONLINEAR DYNAMICAL SYSTEMS. THIS NEUROCOMPUTER, CALLED THE "PARAMETRIC AVALANCHE", WILL INTEGRATE SENSOR DATA FROM ARBITRARY ARRAYS OF SENSORS, DETECT SPACE-TIME PATTERNS, ANDSYNTHESIZE ACTUATOR RESPONSES TO THOSE PATTERNS CONSISTENT WITH MISSION OBJECTIVES AND SYSTEM SURVIVABILITY. THE PROPOSE ...

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 ...

W PRESENT A NOVEL TIME-OF-FLIGHT MASS SPECTROMETER (TOF-MS) BASED SYSTEM FOR DETECTION OF WORKING FLUID LEAKS ABOARD SPACE CRAFT IN FLIGHT. EXPECTED SENSITIVITY OF THE PROPOSEDDEVICES IS SIGNIFICANTLY BETTER THAN THAT OF QUADRUPOLE RESIDUAL GAS ANALYZERS (RGA'S). EXTREMELY SIMPLE IN CONSTRUCTION, THESE TOF DEVICES WILL PROVIDE HIGH PERFORMANCE LEAK DETECTION WITH COMPACT, RELIABLE, AND LOW POWER H ...

DEVICE RESEARCHERS HAVE LONG BEEN HAMPERED BY THE QUALITY AND TYPES OF MATERIALS AVAILABLE FOR THEIR WORK. ELABORATE SOLUTIONS INCLUDING "STRAINED" LAYERS, COMPLEX DOPING, AND THIN LAYER EPITAXY HAVE BEEN EMPLOYED TO TRY AND COMPENSATE FOR POOR SUBSTRATE MATERIALS. MRA HAS SPONSORED 4 YEARS OF RESEARCH AT M.I.T. DEVELOPING THE GROWTH OF VERY HIGH QUALITY CRYSTALS USING LIQUID PHASE ELECTROEPITAXY ...

APPLIED RESEARCH CORPORATION WILL DEVELOP A SOLID STATE STARTRACKER THAT CAN BE REPRODUCED AT LOW COST. THE DESIGN COMBINES COMPONENTS AND CIRCUITS DEVELOPED FOR THE VIDEO CAMERA MARKET WITH DATA PROCESSING AND CALIBRATION METHODS DEVELOPED FOR HIGH-PERFORMANCE STAR TRACKERS. THE IMMEDIATEAPPLICATION OF THIS DESIGN IS TO PROVIDE USERS OF SPACE-BORNE PAYLOADS WITH AN AFFORDABLE, MODERATE TO HIGH PE ...

IN CONTEMPORARY COMPUTATIONAL FLUID DYNAMICS, FINITE DIFFERENCE OR FINITE ELEMENT GRIDS ARE OFTEN GENERATED USINGSTANDARD MESH GENERATION TECHNIQUES. THE BETTER MESH GENERATION PACKAGES ARE CAPABLE OF DEFINING VERY FINE MESHESIN AREAS WHERE THE ANALYST EXPECTS FINE FEATURES OF THE FLOWNEED TO BE SIMULATED. IN RECENT TIMES, SOME MESH GENERATIONSCHEMES HAVE A MEASURE OF ADAPTIVITY IN THEM ALLOWING F ...

THE INNOVATION DESCRIBED HERE IS THE DEVELOPMENT OF A SOFTWARE TOOL, INFOSHELL, THAT ADDRESSES THE PROBLEM OF ASSISTING USERS TO LOCATE AND ACCESS MULTIMEDIA INFORMATION RESIDENT IN HETEROGENEOUS DISTRIBUTED ENVIRONMENTS. INFOSHELL EMBODIES A NOVEL APPROACH WHICH MERGES THE STATE OF THE ART IN USER INTERFACE TECHNOLOGY WITH PROVEN CONCEPTS OF THE "LIBRARY" PARADIGM TO PROVIDE AN ICON-DRIVEN, INTEG ...

SMALL STIRLING CRYOCOOLERS ARE LIMITED IN THE ATTAINMENT OF VERY LOW TEMPERATURES BY THE ADVERSE TREND IN THE RATIO OF VOLUMETRIC HEAT CAPACITY BETWEEN GASEOUS HELIUM AND REGENERATOR MATRIX MATERIALS BELOW ABOUT 40 K. THE PROPOSEDCONCEPT FOR A THERMALLY EFFECTIVE REGENERATOR OVERCOMES THISLIMITATION BY PROVIDING A DYNAMIC HELIUM MATRIX. THE OBJECTIVE OF THE PHASE I PROJECT IS TO EXPERIMENTALLY DEM ...

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, ...
