DUE TO THE BASIC NATURE OF MILITARY OPERATIONS, IT IS SOMETIMES NECESSARY FOR AIR FORCE PERSONNEL TO BE EXPOSED TO TOXIC CHEMICALS IN THEIR WORK ENVIRONMENT EITHER AS A PROTRACTED LOW-LEVEL EXPOSURE OR AS A HIGH-LEVEL, ACUTE EXPOSURE. THE APPLICATION HEREIN PROPOSES TO USE THE ANTERIOR EYE (CORNEA AND CONJUNCTIVA) AND ITS SENSORY INNERVATION AS AN ASSAY OF TOXIC EFFECTS. THE ANTERIOR EYE HAS UNIQU ...

THE ANALYSIS OF AEROBALLISTIC RANGE DATA IS A TEDIOUS AND TECHNICALLY CHALLENGING TASK. THE SOPHISTICATED ANALYSIS PROCEDURES AND REQUIRED SOFTWARE (COMPUTER PROGRAMS) HAVE BEEN REFINED EXTENSIVELY DURING THE PAST FIFTEEN TO TWENTY YEARS WITH THE ADDITION OF THE SIX-DEGREE-OF-FREEDOM CODES EMPLOYING THE MAXIMUM LIKELIHOOD METHOD. THE REQUIRED PROFICIENCY TAKES BETWEEN THREE AND FIVE YEARS UNDER TH ...

CURRENTLY, AS REPORTED IN PROGRAM SOLICITATION 90.1 BY THE AIR FORCE, THE SPECTRUM OF BEARING AND BEARING LINER MATERIALS USED IN THE AIRCRAFT BEARING SYSTEMS BEHAVE IN AN UNEXPECTED WAY WHEN SUBJECTED TO CYCLIC LOADINGS. TO INVESTIGATE THE PROBLEM AND BETTER PREDICT THE FATIGUE LIFE OF THIS ROD AND BEARING SYSTEM, FUNDAMENTAL ANALYSES OF STRESS DISTRIBUTIONS, STRESS INTENSITY FACTORS, FATIGUE CHA ...

ALTHOUGH SPECIALLY DESIGNED END-EFFECTORS HAVE PROVIDED PRESENT DAY ROBOTS AND TELEOPERATOR SYSTEMS WITH THE ABILITY TO DO MANY INTRICATE TASKS, TRUE MANIPULATOR DEXTERITY WILL ONLY COME THROUGH THE USE OF MULTI-FINGERED ANTHROPOMORPHIC MECHANICAL HANDS. STABLE GRASPING OF IRREGULAR OBJECTS, OBJECT RECOGNITION, PRECISION ASSEMBLY, AND PERFORMANCE OF MANY INTRICATE TASKS NOW CONFINED TO HUMANS WILL ...

THE FIRST WALL STRUCTURES FOR FUTURE FUSION REACTORS ARE LIKELY TO CONSIST OF GRAPHITE OR CARBON/CARBON COMPOSITE BRAZED TO AN ACTIVELY COOLED METAL SUBSTRATE. THIS PROJECT INVOLVES A TECHNIQUE FOR VACUUM INFILTRATING ONE SIDE OF THEGRAPHITE WITH MOLTEN COPPER. SUCH INFILTRATED MATERIALS SHOULD BE MORE EASILY BRAZED THAN GRAPHITE OR CARBON/CARBON COMPOSITES. THE RESULTING JOINTS ALSO SHOULD HAVE I ...

THE PURPOSE OF THE PROPOSED PHASE I PROJECT IS TO DEMONSTRATE THAT A USEFUL SOFTWARE INTERFACE CAN BE CONSTRUCTED THAT IS CAPABLE OF FAITHFULLY CONVERTING NORMAL COMPUTER-AIDED DESIGN (CAD) OUTPUT FILES INTO A FORMAT THAT IS DIRECTLY READABLE BY THE GEANT HIGH ENERGY PHYSICS DETECTOR SIMULATION CODE. GEANT, ORIGINALLY DEVELOPED IN THE 1970S, HAS EMERGED AS A STANDARD TOOL FOR DETECTOR SIMULATION; ...

SILICON CARBIDE POSSESSES A UNIQUE COMBINATION OF PROPERTIES THAT ALLOW SIMULTANEOUS HIGH TEMPERATURE AND HIGH POWER OPERATION OF ELECTRONIC DEVICES MADE FROM THIS MATERIAL. THE CUBIC FORM OF SIC (BETA) HAS A WIDE BANDGAP (2.2 EV @ 27 DEG C), WHICH THEORETICALLY GIVES A MAXIMUM OPERABLE TEMPERATURE OF 925 DEG C. ALPHA SIC (6H) HAS AN EVEN WIDER BANDGAP OF 2.86 EV @ 27 DEG C, GIVING A MAXIMUM OPERA ...

THIS PROPOSAL DESCRIBES A TECHNOLOGY WHICH WILL ELIMINATE A MAJOR SOURCE OF ERRONEOUS DATA FROM ONE OF THE MOST IMPORTANT AND COMMONLY USED DOWNHOLE LOGGING TOOLS--THE 14 MEV PULSED NEUTRON SOURCE. BASED ON AN INNOVATIVE NEUTRON DETECTOR CONCEPT, THIS TECHNOLOGY WOULD ALLOW FOR THE NORMALIZING OF DATA DERIVED FROM PULSED NEUTRON SOURCES BY MEASURING THE STRENGTH OF THE UNCOLLIDED FLUX WHILE THE PU ...
