THE OBJECTIVE OF THIS PROJECT IS TO EVALUATE THE FEASIBILITY OF GROWTH OR FUSION OF OPTOELECTRONIC DEVICES DIRECTLY ONTO THE OPTICAL FIBER. THIS APPROACH WILL HAVE SIGNIFICANT IMPLICATION AND BENEFITS ON FUTURE FIBER OPTIC COMMUNICATIONS. TO ACHIEVE THE OBJECTIVE, A COMPLETE LITERATURE SEARCH RELATED TO THE TOPIC WILL BE COMPILED. A THEORETICAL ANALYSIS ON ALL POSSIBLE DESIGNS WILL BE INVESTIGATED ...

A PORTABLE PHOTOMETER IS PROPOSED CONSISTING OF A DEVICE WHICH IS PLACED OVER THE TRAFFIC SIGNAL LENS. AN INTERNAL OPTICAL SYSTEM ALLOWS MEASUREMENT OF THE SIGNAL CANDLEPOWER AT VARIOUS ANGLES OF INTEREST. THE INSTRUMENT ELECTRONICS AND LIGHT EMITTING DIODES PROVIDE A PASS/FAIL INDICATION FOREACH MEASUREMENT ANGLE, WITH THE GO/NO-GO SET POINT BEING AUTOMATICALLY ADJUSTED TO DIFFERENT CANDLEPOWER V ...

THERE IS A WIDESPREAD USE FOR SIC FILAMENT WITH HIGH STRENGTH THEORETICAL DENSITY AND MODULUS IN A SMALL DIAMETER. CURRENT SIC FILAMENT EITHER HAS HIGH POROSITY AT 25% AND LOW STRENGTH OR IS LARGE IN DIAMETER AT 140 M. THIS PROGRAM PRPOSES TO PRODUCE ECONOMICAL HIGH STRENGTH (>500,000 PSI) SIC FILAMENTS WITH THEORETICAL DENSITY AND MODULUS FROM PITCH AND SILICON PRECURSORS. THE PROGRAM UTILIZES KN ...

THE USE OF WHISKERS IN METALS AND CERAMICS IS WELL ESTABLISHED AND DESTINED TO PLAY A MAJOR ROLE IN ADVANCED HIGH TECHNOLOGY MATERIALS APPLICATIONS. THE AVAILABILITY AND COST OF WHISKERS SUCH AS SILICON CARBIDE (SIC) IS A KEY TO THE ECONOMIC PRODUCTION AND WIDESPREAD USE OF ADVANCED COMPOSITE MATERIALS. CURRENTLY, WHISKERS ARE BATCH GROWN IN 6- TO 10-HOUR CYCLES USING STAINLESS STEEL POWDER AS A S ...

CERAMIC LINED COMPOSIED GUN BARRELS OFFER A NEAR IDEAL MATERIALS COMBINATION TO PRODUCE LIGHT WEIGHT GUN BARRELS THAT WILL WITHSTAND 20-30 MM RAPID FIRE BALLISTIC CYCLE OF 1600-1800 DEG F AND PRESSURE UP TO 70,000 PSI FOR LESS THAN 5 MILLISECONDS AT APPROXIMATELY 1/2 THE WEIGHT OF STEEL BARRELS. A UNIQUE FABRICATION METHODOLOGY WILL BE UTILIZED TO APPLY A COMPRESSIVE METAL LAYER TO A CERAMIC LINER ...

SAFETY AND RELIABILITY OF CONTROL ARE FOREMOST CONSIDERATIONS FOR NUCLEAR POWERPLANTS. AS NUCLEAR POWERPLANT CONTROL BECOMES MORE DISTRIBUTED WITH NEXT-GENERATION INTELLIGENT SENSORS, INTEGRATED SIGNAL PROCESSORS, AND SO FORTH, THE NEED FOR MORE RELIABLE PLANT-WIDE COMMUNICATION WILL BECOME INCREASINGLY SIGNIFICANT. BECAUSE THE DISTRIBUTED COMMUNICATION SYSTEM IS THE MOST EXPOSED ELEMENT IN THE OV ...

SCHALLER ASSOCIATES, INC.'S LONG-TERM OBJECTIVE IS TO IMPLEMENT AN EFFECTIVE, AUTOMATED, QUALITY MONITORING PROGRAM FOR HEALTH MAINTENANCE ORGANIZATION (HMO) ADMINISTRATORS. THE PROGRAM WILL GENERATE REPORTS ON PROFILES OF CARE, IDENTIFY EXCEPTIONS TO NORMS, BE PORTABLE TO ALTERNATIVE HMO SETTINGS, BE USABLE BY NURSING AND SUPPORT STAFF, AND WILL HAVE A SIGNIFICANT AND LASTING IMPACT ON QUALITY AS ...

MODERN MILITARY AIRCRAFT ARE EXPECTED TO PROTECT THEIR OCCUPANTS IN CRASHES OF UP TO 42-FT./SEC. SINK RATE, WHICH CAUSES VERY RAPID COMPRESSION OF THE LANDING GEAR SHOCK STRUTS. IN THIS CRASH CONDITION, ONE WAY TO PREVENT EXCESSIVE PRESSURE WITHIN A STANDARD AIR/OIL SHOCK STRUT IS TO DISCHARGE FLUID THROUGH A RELIEF VALVE. THE OBJECTIVE OF THIS PROPOSED EFFORT IS TO DEMONSTRATE FEASIBILITY BY DEVE ...

A FEASIBILITY STUDY OF MEANS OF WEIGHT REDUCTION IN CRASHWORTHY ARMORED CREWSEATS OF THE TYPE USED IN NEWER ARMY HELICOPTERS. THE STUDY SHALL FOCUS PRIMARILY ON THREE APPROACHES TO WEIGHT REDUCTION: A LIGHTER ARMOR SYSTEM THROUGH ADVANCED MATERIALS AND/OR PROCESSES, A LIGHTER STRUCTURE THROUGH THE USE OF HIGH-STRENGTH FIBER COMPOSITE CONSTRUCTION, AND REDUCED PARASITIC WEIGHT THROUGH ADVANCED DYNA ...

THE TREND IN FUTURE U.S. ARMY AIRCRAFT IS TOWARD INCORPORATION OF COMPOSITE MATERIALS IN PRIMARY STRUCTURES TO ACHIEVE WEIGHT REDUCTIONS AND LOWER PRODUCTION COSTS. THIS IS EVIDENCED BY THE ALL COMPOSITE AIRFRAME PROGRAM (ACAP) CURRENTLY BEING FUNDED BY THE ARMY. HOWEVER, THE POTENTIAL WEIGHT SAVINGS IS NOT BEING REALIZED DUE TO THE NEED TO OVERDESIGN TO ACCOUNT FOR THE INHERENTLY BRITTLE NATURE O ...
