THE ESTIMATION OF THE COMPUTER CAPACITIES REQUIRED TO SUPPORT A MISSION ARE USUALLY THE SUBJECT OF MUCH DISCUSSION. ESTIMATES OF THE WORKLOAD AND OTHER PARAMETERS VARY GREATLY. THE REASON FOR THIS IS THAT MOST APPLICATIONS DO NOT FIT THE TRADITIONAL TIMING AND SIZING EFFORT. NONE OF THE THREE COMPONENTS (WORKLOAD, PERFORMANCE REQUIREMENTS AND ARCHITECTURE) IS USUALLY PRESENT. WE CONTEND THAT THE M ...

THIS PROPOSAL WILL DEMONSTRATE (IN 2" TO 4" SIZE), A NOISE REUCING TRIM THAT CAN BE UTILIZED IN ROTARY CONTROL/ON-OFF BALL VALVES. THIS VALVE TRIM ADDRESSES NOISE AT THE SOURCE. THE BASIC DESIGN HAS A VARIABLE IMPEDENCE TRIM TO CAUSE A HIGH IMPEDENCE AT LOW ANGLES OF OPENING AND LOW IMPEDENCE (VERY LITTLE FLOW RESTRICTION) AT LARGE OPENING ANGLES. IT IS AN IDEAL VALVE FOR PRESSURIZATION/DE-PRESSUR ...

OPTICAL COMMUNICATION LINKS HAVE SEVERAL ADVANTAGES FOR SHIP-TO-SHIP APPLICATIONS. KEY FEATURES WHICH MAKE OPTICAL COMMUNICATION ATTRACTIVE INCLUDE HIGH DATA BANDWIDTH AND EASE OF PROTECTION FROM INTERCEPTION. THE PERFORMANCE REQUIREMENTS FOR POINTING AND TRACKING SYSTEMS FOR OPTICAL COMMUNICATION LINKS ARE DEMANDING WHEN EITHER TRANSMITTER OR RECEIVER IS ON A MOVING VEHICLE. CONSEQUENTLY, SUCH SY ...

THE INTENT OF THIS WORK IS TO DEVELOP AN ADVANCED ESTIMATION ALGORITHM FOR MANEUVERING TARGET STATE ESTIMATION AND PREDICTION. THE ALGORITHM WILL BE USED FOR FIRE CONTROL IN THE LOCAL AREA DEFENSE ROLE. THE TARGET STATE ESTIMATOR USES TWO DIMENSIONAL INFRA-RED ELECTRO-OPTICAL IMAGERY AND RADAR DATA TO COMPUTE CURRENT AND PREDICT FUTURE TARGET STATES. INCLUDED IN THIS ANALYSIS WILL BE ALGORITHMS FO ...

THE HIGHLY SUCCESSFUL BOUNDARY LAYER ACOUSTIC MONITOR (BLAM) PROGRAM PRODUCED BLAM GAUGES WHICH WERE USED ON MINUTEMAN FLIGHTS TO TEST FLOW AROUND RE-ENTRY VEHICLES (RV), AND DETECT THE LOCATION OF THE TRANSITION TO TURBULENT FLOW. IT IS POSTULATED THAT THESE BLAM GAUGES CAN BE RECONFIGURED TO OPERATE TO DETECT TURBULENT FLOW IN WATER TUNNELS. IN ORDER TO EFFECT THIS REDESIGN, THE WATER TUNNEL ENV ...

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 ...
