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 ...

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 EMERGENCE OF ARTIFICAL INTELLIGENCE AND EXPERT SYSTEMS TECHNOLOGY FROM THE LABORATORY ENVIRONMENT INTO GENERAL PRACTICE OFFERS A PROMISING APPROACH FOR THE DEVELOPMENT OF MANUFACTURING APPLICATIONS. MANUFACTURING SYSTEMS BUILT WITH THIS TECHNOLOGY WILL BE PARTICULARLY VALUABLE FOR SECOND AND THIRD TIER SUBCONTRACTORS IN THE DEFENSE INDUSTRY, BECAUSE THEY WILL ALLOW THE CAPTURE AND TRANSMISSION ...

IN THIS PROJECT, AN ADVANCED UNDERWATER ACOUSTIC INTENSITY MEASUREMENT SYSTEM WILL BE DESIGNED, BUILT AND TESTED. THIS SYSTEM CONSISTS OF A MULTI-SENSOR PROBE-TYPE ARRAY, A REAL-TIME SPECTRUM ANALYZER AND A MINI-COMPUTER SYSTEM WITH BUILT-IN IN-SITU CALIBRATION CAPABILITY. THE SYSTEM IS CAPABLE OF MEASURING, DISPLAYING, AND MEMORIZING: (A) THREE ORTHOGONAL ACOUSTIC INTENSITY VECTORS AND THE TOTAL ...

TWO MECHANISMS ARE IDENTIFIED BY WHICH AN ELECTRICALLY CHARGED ROTORCRAFT MIGHT ACT AS A SOURCE OF ELECTROMAGNETIC RADIATION. THESE ARE NARROW BAND ELF RADIATION PRODUCED BY CURRENTS INDUCED BY ROTOR ROTATION AND BROADBAND ELECTROMAGNETIC RADIATION FROM P STATIC. IN ORDER TO DETERMINE WHETHER OR NOT RADIATION DUE TO THESE MECHANISMS IS DETECTIBLE A COMBINATION OF NUMERICAL MODELLING TECHNIQUES IS ...
