OPTOELECTRONIC SOURCES, INTEGRATED AS MONOLITHIC ELEMENTS ON SILICON VLSI CHIPS, OFFER IMPORTANT ADVANTAGES IN THE TRANSMISSION OF INFORMATION WITHIN THE CHIP OR BETWEEN CHIPS IN ADVANCED COMPUTER SYSTEMS. THE SPEED OF OPTICAL-INTEGRATED VLSI DEVICES IS EXPECTED TO BE CONSIDERABLY HIGHER THAN EQUIVALENT VLSI WITH METALLIC INTERCONNECTS, DUE TO ABSENCE OF THE RC DELAY INHERENT IN THE METALLIC CONDU ...

THE PURPOSE OF THIS RESEARCH IS TO STUDY THE FEASIBILITY OF QUANTIFYING THE EFFECTS OF IREASED AUTOMATION ON THE WORKLOAD AND PERFORMANCE OF THE FEDERAL AVIATION ADMINISTRA-TION'S AIR TRAFFIC CONTROLLER. IN PHASE I, RESEARCH WILL FOCUS ON ADAPTRING OUR CURRENT HUMAN PERFORMANCE MODEL TO REPRESENT THE JOB CHARACTERISTICS OR ATTRIBUTES THAT WILL DETERMINE LEVELS OF WORKLOAD AND PERFORMANCE IN THE AD ...

THE PROPOSED PROJECT AIMS TO EXPLOIT THE HIGH-SPEED ELECTRO-OPTIC PROPERTIES OF FERROELECTRIC LIQUID CRYSTALS (FLCS) TO MAKE OPTICAL CROSSBAR SWITCHES. THESE SWITCHES WOULD ALLOW LARGE NUMBERS (HUNDREDSTO THOUSANDS) OF INPUT LIGHT BEAMS MODULATED AT GHZ RATES TO BE CONNECTED IN ANY POSSIBLE ONE-TO-ONE PATTERN TO AN EQUALLY LARGE NUMBER OF OUTPUTS. THE PROPOSED SWITCH GEOMETRIES PROMISE THAT ONLY A ...

THE RECOGNIZED LOW LEVEL WIND SHEAR PHENOMENON KNOWN AS A MICROBURST POSES A SERIOUS AIR SAFETY THREAT TO COMMERCIAL AVIATION WHILE IN A LANDING OR POSES A SERIOUS COMMERCIAL AVIATION WHILE IN A LANDING OR TAKEOFF PATTERN. THIS LOW LEVEL WIND SHEAR HAS BEEN DEMONSTRATED TO DE A THIS LOW LEVEL WIND SHEAR HAS BEEN DEMONSTRATED TO BE A MAJOR CONTRIBUTING FACTOR TO SEVERAL CRASHES OF COMMERCIAL AIRLIN ...

THE PURPOSE OF THIS PHASE I PROGRAM IS TO IDENTIFY SPECIFIC TACTICAL AVIONICS APPLICATIONS WHICH COULD BENEFIT FROM THE SPECIAL INFORMATION-PROCESSING CAPABILITIES OF ADAPTIVE NEURAL NETWORKS. FOR SPECIFIC TACTICAL APPLICATIONS, A TRADE-OFF ANALYSIS OF SPECIFIC NEURAL NETWORK ARCHITECTURES WILL BE CONDUCTED WITH THE OBJECTIVE OF SELECTING THE MOST PROMISING ARCHITECTURES. A PHASE II PLAN WILL BE P ...

A STUDY OF THE EFFICIENCIES AND ENGINEERING TRADE-OFFS INTEGRATING REDUNDANT NUMBER SYSTEM WITH SYSTOLIC ARRAY PROCESSING ELEMENTS IN ORDER TO CAPTURE THE INHERENT FAULT TOLERANT PROPERTIES OF SIGNED DIGITS IS PROPOSED. USING SIGNED DIGITS REDUCES CARRY/BORROW DISTANCE TO A MINIMUM THUS REALIZING HIGHLY MODULARIZED AND COLUMNAR ARITHMETIC ENGINES. PROCESSING CELLS BECOME REGULAR WITH FEWER INTERCO ...
