A MODULAR INPUT/OUTPUT SUBSYSTEM IS PROPOSED TO PROVIDE INTERFACE BETWEEN EXPERIMENTAL DATA ACQUISITION SYSTEMS USING THE CAMAC OR FASTBUS STANDARDS AND NEW-GENERATION DIGITAL EQUIPMENT CORPORATION MINICOMPUTERS. THE SYSTEM OFFERS A POTENTIAL TENFOLD INCREASE IN THE SPEED OF DATA ACQUISITION OVER CURRENT SYSTEMS. IT INCLUDES SUFFICIENT COMPUTER INTELLIGENCE TO MANAGE DATA TRANSFERS BETWEEN THE EXP ...

A RESEARCH EFFORT COMPLETED RECENTLY FOR THE AIR FORCE IDENTIFIED NEW TECHNOLOGIES FOR ANGULAR MOTION MEASUREMENT. TWO CONCEPTS WERE FOUND WHICH APPEAR TO OFFER POTENTIAL FOR AN EXCELLENT COMBINATION OF SMALL SIZE, WIDE DYNAMIC RANGE, WIDE BANDWIDTH AND EASE OF FABRICATION AND UTILIZATION. ONE DEVICE, CALLED A FLUID-FILLED BENDER BEAM, USES PIEZOCERAMICELEMENTS TO PRODUCE A SIGNAL PROPORTIONAL TO ...

THE PROPOSED PROJECT WILL DEVELOP A NEW DAYLIGHTING DESIGN METHOD BASED ON A "LUMEN-DAY" CONCEPT. THE ESSENCE OF THE LUMEN-DAY METHOD IS A STATISTICAL CLIMATIC DATA BASE, SIMILAR IN CONCEPT TO THE HEATING AND COOLING DEGREE-DAY METHOD OF ENERGY ANALYSIS, GENERATED THROUGH THE INTERROGATION AND ANALYSIS OF TMY/TRY WEATHER TAPES. THE LUMEN-DAY DATA BASE WOULD BE A STATISTICAL SUMMARY OF THE DAYLIGHT ...

THE EFFECT OF SCALING DOWN DEVICE DIMENSIONS OF VLSI STRUCTURES AND THE COMBINATION OF INCREASED CIRCUIT COMPLEXITY DURING THE SCALING PROCESS IS PLACING SEVERE LIMITATIONS ON THE MINIMUM PROPAGATION DELAY OF METALLIC INTERCONNECTS. OPTICAL INTERCONNECTS REMOVE THOSE SPEED LIMITATIONS AND OFFER A DEGREE OF FLEXIBILITY THAT ELECTRICAL INTERCONNECTS COULD NEVER OBTAIN. THE KEY OPPORTUNITY IS TO INTE ...

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 ...

ALTHOUGH TECHNOLOGY IS ADVANCING AT AN EVER INCREASING PACE,ITS APPLICATION FOR USE BY HANDICAPPED INDIVIDUALS HAS BEEN SLOW. SEVERELY IMPAIRED INDIVIDUALS OFTEN REQUIRE SOME TYPE OF "HIGH TECHNOLOGY" MEANS TO ENABLE THEM TO HAVE A DEGREE OF MOBILITY. THE SPECIFIC AIM OF THIS PROGRAM IS TO INVESTIGATE THE POTENTIAL OF USING ELECTRO-OPTICS AS A MEANS FOR THE HANDICAPPED TO EFFECT CONTROL OF HIS/HER ...

METHODS FOR RELIABLY ASSESSING THE STRENGTH OF CONCRETE MEMBERS WILL BE DEVELOPED USING NONDESTRUCTIVE EVALUATION (NDE) PROCEDURES INVOLVING SPECTRAL ANALYSIS OF STRESS-WAVE PARAMETERS. THESE PROCEDURES ARE BASED ON THE EXTENSION OF PREVIOUS RESEARCH ON NDE OF CONCRETE AND THE VAST EXPERIENCE OF THIS STAFF IN NDE AND SPECTRAL ANALYSIS OF WOOD-BASED STRUCTURES. DEVELOPMENT OF A RELIABLE, ACCURATE N ...

THE USE OF ADHESIVE JOINTS IN THE CONSTRUCTION OF VARIOUS PRODUCTS IS AN ATTRACTIVE ALTERNATIVE TO MECHANICAL FASTENERS. THE GREATEST PROBLEM IS STRUCTURAL BONDING IS THE INABILITY TO QUANTIFY THE STRENGTH OF THE BONDED ASSEMBLY FOR DESIGN, QUALITY CONTROL OR MAINTENANCE. CURRENT NONDESTRUCTIVE EVALUATION METHODS HAVE NOT BEEN SUCCESSFUL IN SOLVING THIS PROBLEM. THIS PROPOSAL IS DIRECTED TOWARD TH ...
