THIS PROPOSAL SEEKS TO DEVELOP AND IMPLEMENT A DISTRIBUTED DATA MANAGEMENT NETWORK FOR CANCER CLINICAL TRIALS. THE NETWORK WILL BE MICROCOMPUTER BASED AND WILL HAVE AS ITS OBJECTIVE A CENTRALIZED DATABASE FOR MONITORING THE PROGRESSOF CLINICAL TRIALS. FEATURES WILL INCLUDE DATA ENTRY USING PREFORMATTED SCREENS, AUTOMATED ERROR CHECKING, EDITING FACILITIES, DATA SECURITY, AND DATA TRANSFER CAPABILI ...

THIS RESEARCH WILL INVESTIGATE PERFORMANCE MEAUREMENT TECHNIQUES AND COMPUTER SIMULATION TECHNIQUES REQUIRED FOR AN ON-BOARD AIRCRAFT "EMBEDDED TRAINING" CAPABILITY APPLICABLE TO BOTH TRAINING AND MUNITION CONCEPT EVALUATION. DATA REQUIREMENTS FOR ON-BOARD SIMULATION OF THE MUNITIONS TO ACCOMPLISH SIMULATED LAUNCH, FLYOUT AND TERMINAL ENGAGEMENT WILL BE DETERMINED. AVAILABILITY OF REAL-WORLD INPUT ...

N/A

THE SEEMINGLY IMPOSSIBLE TASK OF PRODUCING ONE-HALF OF A MEGAWATT OF ACOUSTIC POWER UNDERWATER AT A FREQUENCY OF 5 HZ IS ADDRESSED. THE EXPLOITATION OF THE RECENT INTRODUCTION OF NEW RARE EARTH PERMANENT MAGNET MATERIALS, THE CONCEPT OF USING A FLEXURAL DISC RADIATOR, AND THE RECENT CULMINATION OF TWO YEARS OF ELECTRODYNAMIC TRANSDUCER DEVELOPMENT IS PROPOSED. THE USE OF MATHEMATICAL MODELING, EXP ...

MOVING-COIL TRANSDUCERS ARE USUALLY ASSOCIATED WITH LOW POWER, LOW EFFICIENCY, BROADBAND AND VERY LOW FREQUENCY APPLICATIONS. THE RECENT INTRODUCTION OF RARE EARTH PERMANENT MAGNETIC MATERIALS HAVING HIGH ENERGY DENSITIES AND THE RECENT DEVELOPMENT OF BETTER DESIGN TECHNIQUES SIGNIFICANTLY IMPROVE EFFICIENCY, POWER HANDLING ABILITY, AND HIGH FREQUENCY OPERATION. THE APPLICATION OF THESE IMPROVEMEN ...

HEARING TESTING OF NEWBORNS AND INFANTS USING AUDITORY BRAINSTEM RESPONSES (ABR) HAS GAINED WIDESPREAD ACCEPTANCE AND HAS COME TO BE PREFERRED OVER OTHER LESS ACCURATE TECHNIQUES. ABR'S STRENGTH IS ITS DIRECT MEASUREMENT OF AUDITORY FUNCTION, WHICH RESULTS IN HIGH TEST SPECIFICITY AND SENSITIVITY. CLINICAL USE OF ABR, HOWEVER, IS STILL LIMITED BECAUSE OF THE PROFESSIONAL LABOR-INTENSIVE OPERATION ...

THE DIGITAL SIGNAL PROCESSING (DSP) INDUSTRY SUPPLIES ESSENTIAL TOOLS AND TECHNOLOGY TO A HOST OF DEFENSE AND CIVILIAN END-USERS. DSP PRODUCTS ARE FOUND IN MANY FIELDS INCLUDING COMMUNICATIONS, AUDIO, VIDEO, AUTOMATION, GEOPHYSICAL, MEDICAL, AND RADAR/SONAR APPLICATIONS. HOWEVER, MANY CRITICALLY IMPORTANT PROBLEMS CANNOT BE SERVEDBY THIS INDUSTRY DUE TO CURRENT COMPUTATIONAL LIMITATIONS OFDSP HARD ...

AN "INTELLIGENT" MECHANISM TO CONTROL AIRCRAFT TURBINE ENGINE COOLDOWN UTILIZING INTEGRAL SENSORS, LOGIC, DRIVE AND FAIL-SAFE, FOR EXTENDING THE PERFORMANCE LIFE OF AIRCRAFT GAS TURBINE ENGINES IS PROPOSED. AIRCRAFT TURBINE ENGINES ARE PRECISELY MADE AND CONTROLLED MECHAISMS UNTIL SHUTDOWN. THEN, HEAT SOAK AND SOAKBACK PHENOMEN DELETERIOUSLY AFFECT ENGINE PERFORMANCE, LIFE, MAINTENANCE COSTS AND L ...

AN/PSC-2 DIGITAL COMMUNICATION TERMINAL (DCT) REQUIRES A POWER CONVERTER THAT CONVERTS 115 VAC TO 8 VDC FOR ABOARD SHIP USAGE. THE HIGH TEMPERATURE AND HUMIDITY CONDITION ON THE SHIP, COMBINING WITH THE POSSIBLE SALTY ATMOSPHERE CAN GREATLY LOWER THE RELIABILITY OF ANY ELECTRONIC DEVICE BECAUSE OF THEIR CORROSIVE ACTION ON THEM. THE PROPOSED CONVERTER IS BELIEVED TO SURVIVE THE HARSH ATMOSPHERE CO ...
