THE ARS-9 PRIMARY SURVEILLANCE RADAR HAS A DIGITAL OUTPUT INSTEAD OF THE ANALOG OUTPUT OF IT'S PREDECESSORS. THE COMPUTER AND DISPLAYS EQUIPMENT FOR NAVAL AIR TRAFFIC CONTROL COMPUTER NEEDS DIFFERENT DATA THAN THE ASR-9, NOW SUPPLIES. AN INTERFACE WILL BE DESIGNED THAT WILL TAKE THE OUTPUT OF THE ASR-9 EITHER FROM MODEM OR FIBER OPTICK LINK OR MICROWAVE LINK OR ON-SITE ATTACHMENT AND CONVERT FOR T ...

BASED UPON THERMODYNAMIC DATA AND EXPERIMENTAL RESULTS, AMI HAS DETERMINED THAT ZIRCONIUM DIBORIDE IS ONE OF THE FEW CERAMIC MATERIALS THAT IS CHEMICALLY COMPATIBLE WITH TITANIUM METAL AT ELEVATED TEMPERATURES. THEREFORE, THIS CERAMIC MATERIAL, REINFORCED WITH SUITABLE CERAMIC WHISKERS, SHOULD BE AN IDEAL CANDIDATE TO REPLACE TUNGSTEN CARBIDE AS A MACHINE TOOL INSERT FOR MACHINING TITANIUM ALLOYS. ...

A MEMBRANE TYPE WAFER PROBE IS PROPOSED WHICH, AT THE END OF PHASE II, WILL ACHIEVE TRANSMISSION OF SIGNALS FROM TESTER TO DIE WITH LOW ABBRATIONS FOR A 100 PS RISETIME. CAPABILITIES WILL INCLUDE LOW-IMPEDANCE GROUND AND POWER CONTACTS, WITH LSI-LEVEL NUMBERS AND DENSITIES OF SIGNAL LINES. PHASE I WORK WILL DETERMINE THE DESIGN PARAMETERS NECESSARY FOR THESE GOALS THROUGH A SEQUENCE OF CALCULATION ...

THE MISSION OF THIS PHASE I PROJECT IS COMPLETION OF A TRULY INNOVATIVE STUDY TO UPGRADE EXISTING PNS CODES FOR COMPUTING HIGHSPEED, THREE-DIMENSIONAL RE-ENTRY FLOWFIELDS. THE PLAN OF ACTION ENCOMPASSES A THOROUGH EXAMINATION OF THE RANGE OF ADMISSABLE CFD THEORIES, TO UNEQUIVACALLY COMPARE STRONG AND WEAK POINTS FOR APPLICATION TO THE REYNOLDS-AVERAGED NAVIER-STOKES EQUATIONS WITH DIFFERENTIAL EQ ...

THE STATE-EVENT CALCULUS (SECALC) IS A META-MODEL FOR SOFTWARE SYSTEM BEHAVIOR. STATES REFER TO SITUATIONS OF SOME DURATION WHILE EVENTS REFER TO SYSTEM ACTIONS PERFORMED BY SYSTEM ENTITIES IN RELATION TO OTHER SYSTEM ENTITIES AND EXTERNAL INPUTS. THE MAIN OBJECTIVES GUIDING THE INITIAL DEVELOPMENT OF SECALC WERE THAT: 1) IT BE COMPREHENSIBLE, 2) IT BE DERIVABLE FROM FUNCTIONAL SPECIFICATIONS (WIT ...

THIS PROPOSAL DESCRIBES THE FIRST PHASE OF A PROJECT WHICH WILL DEVELOP AN EXPERT SYSTEM CAPABLE OF SELECTING OPTIMAL FORCE REFLECTION LEVELS IN REAL-TIME DURING TELEOPERATION. THERE ARE THREE GOALS FOR PHASE I: 1) DELINEATION OF TASK SITUATIONS IN WHICH FORCE-FEEDBACK IS HELPFUL; 2) DEVELOPMENT OF EXPERIMENTAL METHODS FOR TESTING THE EFFECT OF DIFFERENT FEEDBACK LEVELS ON RATE OF LEARNING, ASYMPT ...

THIS PROPOSAL WOULD ENCOMPASS THE DESIGN AND FABRICATION OF SOLID STATE POWER SWITCHES AS HYBRID CIRCUITS. THE CIRCUITS WOULD CONTAIN PARALLEL OUTPUT TRANSISTORS, ALL REQUIRED CURRENT DRIVE STAGES, HIGHTEMPERATURE AND HIGH-CURRENT PROTECTION. TEMPERATURES ARE MEASURED WITH SCREEN PRINTED OR CHIP THERMISTORS AND CURRENT WILL BE MONITORED AS A VOLTAGE ACROSS A SENSE RESISTOR OR OTHER METHOD YET TO B ...

THE RECENT DISCOVERY OF HIGH TEMPERATURE SUPERCONDUCTORS HAS LED TO RENEWED INTEREST IN THE LARGE-SCALE APPLICATION OF SUPERCONDUCTIVITY. THE PRIMARY OBSTACLE TO THE USE OF THESE MATERIALS IS THE PRESENT INABILITY TO PRODUCE MATERIAL IN USABLE FORMS WITH ADEQUATE CURRENT CARRYING ABILITY AND MECHANICAL PROPERTIES. THE PRESENT PROJECT INVOLVES INVESTIGATION OF THE FEASIBILITY OF FABRICATING SUPERCO ...
