DUE TO THE DOWNSIZING OF AUTOMOBILES ON U.S. HIGHWAYS, MINI-CARS HAVE BECOME A MAJOR PART OF THE AUTO POPULATION. THE LIGHT WEIGHT AND HIGH CRUSH RATE OF THESE VEHICLES CAN CAUSEHIGH VELOCITY CHANGE LEVELS WHEN IMPACTING MOST EXISTING BREAKAWAY LUMINAIRE SUPPORTS. THIS INCREASES THE PROBABILI-TY OF INJURY TO OCCUPANTSOF MINI-CARS WHEN IMPACTING LUMI- NAIRE SUPPORTS. CONCEPTS HAVE BEEN DEVELOPED WH ...

THERE HAS BEEN LITTLE, IF ANY, DEVELOPMENT IN RECENT YEARS IN THE AREA OF MECHANICAL SHOCK (MS) SENSORS, ESPECIALLY SENSORS WITH HIGH FREQUENCY AND HIGH-G RESPONSE. IT IS PROPOSED THAT THROUGH THE USE OF LITERATURE SOURCES AN ASSESSMENT BE MADE OF THE STATE-OF-THE-ART IN MS SENSORS AND OF THE IMPROVABILITY OF THE MOST ADVANCED DEVICES TO EXTEND THEIR FREQUENCY AND DYNAMIC RANGE. IT IS ALSO PROPOSE ...

THE PROPOSAL IS CONCERNED WITH THE DEVELOPMENT OF A NEW CONCEPT FOR THE CONTROL OF THE AERODYNAMICS OF HELICOPTER ROTOR BLADES. SUCH A CONTROL DEVICE WILL MAKE IT POSSIBLE TO MECHANIZE THE HELICOPTER ROTOR AIR FOIL MUCH IN THE SAME WAY THAT THE WINGS OF FIXED WING AIRCRAFT ARE MECHANIZED TO ACHIEVE HIGH LIFT, STALL-FREE PERFORMANCE AT LOW SPEEDS. EXISTING METHODS FOR ACTIVE CONTROL OF HELICOPTER R ...

MERCURY CADMIUM TELLURIDE (MCT) HAS EMERGED AS THE SUPERIOR MATERIAL FOR INFRARED APPLICATIONS IN IMPORTANT 3-5 MICROMETER AND 8-13 MICROMETER RANGES CORRESPONDING TO ATMOSPHERIC WINDOWS. BULK GROWTH METHODS CANNOT PROVIDE DEVICE GRADE LARGE AREA CRYSTALS OF THIS MATERIAL. HENCE, IN ORDER TO REALIZE THE STATE-OF-THE-ART LARGE AREA DEVICES, EPITAXIAL GROWTH IS THE ONLY PLAUSIBLE TECHNIQUE AT THE PR ...

PROPOSES A RECONFIGURED KIORITZ DM-9 BACKPACK SPRAYER THAT WILL (1) DISPENSE METERED VOLUME OF PEDICULICIDE, (2) EMPLOY EXISTING SYSTEM ENERGY SOURCE, (3) ACCESS 17 DISPERSAL SITES/PERSON, AND (4) MAINTAIN ADEQUATE FLOW DIAMETERS. A DESIGN IS POSTULATED THAT INCORPORATES VACUUM ACTUATED SLIDE VALVES, A METERING CHAMBER, AND NOZZLE EFFECTIVENESS. A SURVEY OF PREVIOUS RESEARCH AND TESTING WILL BE CO ...

A CONCEPT FOR USING SIDEBAND MODULATIONS TO CREATE A MONOPULSE LIKE GUIDANCE SIGNAL SUITABLE FOR USE BY A MISSILE IN FLIGHT IS PRESENTED. THIS APPROACH OFFERS ADVANTAGES OVER A TRUE MONOPULSE WHICH INCLUDE: VERY LOW COST/SIMPLE ON-BOARD RECEIVER; REDUCE MULTI-PATH PROBLEMS DUE TO LOW ANGLE CLUTTER; AND, GROWTH POTENTIAL TO INCLUDE RANGE INFORMATION NECESSARY FOR USE WITH AN ACTIVE TERMINAL GUIDANC ...

THE OBJECTIVE OF THE PROPOSED PROGRAM IS TO DEVELOP A FIELD STEAM GENERATOR CAPABLE OF USING ANY UNTREATED WATER. THE PROPOSED CONCEPT UTILIZES HEAT PIPES AS INTERMEDIATE HEAT TRANSFER ELEMENTS BETWEEN THE BURNER AND THE BOILER SECTIONS. THE INCORPORATION OF HEAT PIPES CONVERTS THE STEAM GENERATOR FROM A "WATER TUBE" TO A "FIRE TUBE" BOILER. STEAM LOCOMOTIVES HAVE USED THIS DESIGN FOR OVER A CENTU ...

THE MOST STRAIGHTFORWARD WAY TO MEASURE OPERATIONAL PERFORMANCE IS TO MEASURE IT ON THE JOB. HOWEVER, WHEN SUCH MEASURES ARE EMPLOYED, THEY ARE GENERALLY INSENSITIVE TO ALL BUT THE MOST POWERFUL STRESSOR EFFECTS. ONE OF THE CONTRIBUTING PROBLEMS TO THIS ISSUE IS THE LACK OF RELIABILITY. INSUFFICIENT ATTENTION TO RELIABILITY CAN LEAD TO REDUCTION OF STATISTICAL POWER, HIGHER SAMPLE SIZE REQUIREMENT ...

VERY RECENTLY, AN OPTICAL INSTRUMENT FOR MEASURING SIZES AND CONCENTRATIONS OF SPHERICAL PARTICLES IN A PIPELINE HAS BEEN DEVELOPED BY THE PRINCIPAL INVESTIGATORS. BASED ON THIS EXPERIENCE, WE PROPOSE TO INVESTIGATE THE FEASIBILITY OF DEVELOPING A RELIABLE OPTICAL PARTICLE INSTRUMENT WHICH WILL MEET THE FOLLOWING REQUIREMENTS: (1) IT CAN MEASURE SPATIAL AND TEMPORAL DISTRIBUTIONS OF PARTICLE VELOC ...
