IT IS PROPOSED THAT AN AUTOMATED LEARNING SYSTEM CAN BE DEVELOPED TO TRAP THE KNOWLEDGE OF AN EXPERIENCED MANUFACTURING PLANNER AND INCORPORATE IT INTO AN EXPERT SYSTEM. THE LEARNING SYSTEM WOULD WORK IN THE ENVIRONMENT OF AN EXPERIENCED PLANNED USING AN EXISTING AUTOMATED PLANNING SYSTEM (APS) TO DESIGN A SMALL PART. A RUDIMENTARY EXPERT SYSTEM WOULD BE CREATED FROM EXISTING SHELLS AND DESIGNED T ...

A RESEARCH PROGRAM IS PROPOSED TO ESTABLISH THE FEASIBILITY OF COMBINING THE COMPREHENSIVE RULE-BASE OF AN EXPERT ARC WELDING SYSTEM WITH SENSORY FEEDBACK AND CONTROL ALGORITHMS TO INITIALLY SET AND ADAPTIVELY CONTROL THE WELD PROCESS IN A CHANGING ENVIRONMENT. IT WILL BE THE OBJECTIVE OF THE PROPOSED RESEARCH TO DEMONSTRATE THE FEASIBILITY OF ACCOMPLISHING THIS FOR BOTH CONVENTIONAL JOINTS AND NA ...

FATIGUE LIFE ENHANCEMENT OF BUSHED TITANIUM LUGS WILL BE INVESTIGATED. A UNIQUE TECHNBIQUE, FORCEMATE (FM), FOR INSTALLATION OF BUSHINGS WILL BE DEMONSTRATED. EFFECT OF PROCESS PARAMETERS WILL BE EVALUATED AND THOSE PARAMETERS OPTIMIZED FOR THE PARTICULAR CONFIGURATION UNDER INVESTIGATION. AT EACH PHASE OF THE INVESTIGATION, FATIGUE LIFE COMPARISONS WILL BE MADE BETWEEN LUGS AND BUSHINGS INSTALLED ...

THE PROPOSED WORK WILL EVALUATE THE FEASIBILITY OF HAFNIUM CARBIDE FIBERPRODUCTION THROUGH PYROLYSIS OF ORGANOHAFNIUM POLYMER PRECURSORS. IN THIS CHEMICAL APPROACH TO CERAMIC PROCESSING, THE METHODS TO SYNTHESIZE ORGANOMETALLIC CHEMICALS SUITABLE FOR THE FORMATION OF ORGANOHAFNIUM POLYMERS AND TO FORM POLYMERIC FIBERS WITH AN (-HF-CHF-) BACKBONE WILL BE EXPLORED. THE POLYMERS WILL THEN BY PYROLYZE ...

HISTORICAL FAILURE DATA SHOW SOME SIXTY PERCENT OF INTEGRATED CIRCUIT FAILURES CAN BE TRACED TO INADEQUATE PROVISION FOR HEAT DISSIPATION. IMPROVING AVIONICS RELIABILITY REQUIRES FINDING REGIONS OF UNDUE THERMAL RESISTANCE IN THE COOLING AIR PATH FROM THE DEDICATED VAPOR CYCLE ENVIRONMENTAL CONTROL SYSTEM THROUGH SUPPLY DUCTING, RACK, SHELF, CAGE, CARD TO COMPONENT CASE. THE IMPERATIVE IS CONTROL ...

THE PROPOSED PROGRAM OFFERS AN INNOVATIVE APPROACH FOR PROTECTING A BATTLE GROUP FROM ATTACKS BY ADVANCED ANTI-SHIP MISSILES. SPACIALLY DISTRIBUTED COUNTERMEASURES, OF VARIOUS TYPES, ARE DEPLOYED IN A COORDINATED MANNER SO AS TO COUNTER ALL PHASES AND ASPECTS OF THREAT MISSILE WEAPON SYSTEMS. THESE COORDINATED COUNTERMEASURES TECHNIQUES ARE APPLIED SEQUENTUALLY AND THEIR EFFECTIVENESS AGAINST EACH ...

WHILE EDUCATORS READILY ACKNOWLEDGE THE POTENTIAL VALUE OF INTEGRATING VOICE AND SOUND INTO COMPUTER-BASED INSTRUCTION, APPLICATIONS OF SPEECH HAVE BEEN SLOW TO DEVELOP. EARLY ATTEMPTS AT CREATING MULTIPLE MODALITY ENVIRONMENTS HAVE BEEN EXPENSIVE BECAUSE OF THE NEED FOR SPECIAL ADD-ON EQUIPMENT AND FOR THE MOST PART, THE QUALITY OF THE SPEECH OFFERED BY THESE PRODUCTS HAS NOT MET EDUCATORS EXPECT ...
