Individual differences in vulnerability to sleep loss and fatigue from extended work hours and night work are a substantial problem in transportation policy making, work schedule development, fatigue risk management strategies, and prediction of performance impairment in real-world operations (Van Dongen et al. 2003; Mollicone et al. 2010). Our group was the first to document the considerable magn ...

ABSTRACT: The challenges in the operations of small unmanned aircraft systems (SUAS) and micro air vehicles (MAVs) in terms of required agility and benign flying qualities require a superior understanding of their basic flight mechanics and vehicle dynamics. Flight test data for MAVs are sparse, and wind tunnel unsteady aerodynamic data of MAVs with flexible wing structures are non-existent. Alth ...

ABSTRACT: TRS Technologies, Inc. proposes to develop nonlinear dielectric ceramic capacitors for discharge pulse power application and reduce the production cost of cofired multilayer capacitors. In the phase I program TRS developed a new antiferroelectric composition showing energy density>4J/cc at a field as low as 200kV/cm and demonstrated that high breakdown strength can be achieved from ant ...

ABSTRACT: The proposed program will provide three important products to the space electronics community: [A] An extremely rad-hard (estimated>3Mrad) high isolation and processor-free converter that can provide an (unregulated) intermediary voltage that can supply 6V/20V at 25W/40W respectively. [B] An extremely rad hard high isolation and processor-free converter that can provide an unregulated ...

ABSTRACT: Development of an operational prototype Test Data Aggregation and Analytical System (TDAAS) at Arnold Engineering Development Center (AEDC). TDAAS will address the customer"s need for data integration and knowledge discovery of Department of Defense (DoD) weapons system engine and flight test data at AEDC. The desired end-state for this project will be TRL 7 at AEDC providing test perso ...

ABSTRACT: An exhaust plume is a primary observable to warning sensors designed to protect low flying aircraft from MANPADS and other hostile threats such as RPG's and small arms fire with tracers. The design of current and future warning sensors and countermeasures need a complete characterization of this observable. This effort is designed to transition image morphing technology, tailored ...

ASTROPOWER IS PROPOSING THE DEVELOPMENT OF AN ULTRA-LIGHTWEIGHT, HIGH PERFORMANCE, THIN LIGHT TRAPPING GAAS SOLAR CELL FOR ADVANCED SPACE POWER SYSTEMS. A THIN DEVICE LEADS TO HIGHER PERFORMANCE IN TERMS OF OPEN CIRCUIT VOLTAGE, RADIATION RESISTANCE, AND SPECIFIC POWER. IN A THIN DEVICE, THE INCORPORATION OF LIGHT TRAPPING TO EXTEND THE OPTICAL PATH LENGTH PERMITS GREATER CURRENT GENERATIC THAN CA ...

TRADITIONALLY, THE DETONATION HAS BEEN TREATED BY THE SHOCK THEORY, AND EXPLOSIVES AND PROPELLANTS HAVE BEEN CONSIDERED AS ENERGETIC FLUIDS. MANY SOLID PROPERTIES HAVE NOT BEEN MEASURED AND ARE NOT AVAILABLE FROM THE HANDBOOKS. RECENT RESULTS IN MUNITION SENSITIVITY STUDIES SHOW THAT SHEARING IS ONE OF THE MAIN MECHANISMS IN CAUSING DETONATION, AND IS CONTROLLED BY CERTAIN SOLID PROPERTIES. IN THE ...

THIS PROPOSAL DESCRIBES THE EFFORTS REQUIRED TO STUDY THE EFFECTS OF VARIOUS MATERIALS ON THE REDUCTION OF ELECTRONIC INTERFACE IN THE PLASMA OF A RE-ENTRY VEHICLE HEAT SHIELD. A FUNDEMENTAL UNDERSTANDING OF THE MECHANISM BY MEANS OF WHICH THESE MATERIALS ACHIEVE A REDUCTION IN ELECTRONIC INTERFERENCE IS THE GOAL OF THE PROPOSED INVESTIGATIONS, IN WHICH THE GSI FLAME TEST APPARATUS IS USED TO DETE ...

THERE IS A RAPIDLY GROWING NEED FOR TOOLS FOR THE DESIGN AND SYNTHESISOF ELECTRONIC SYSTEMS AND MULTI-DEVICE CIRCUITS: TO SUPPORT GREATER CLOCK SPEEDS; PACKAGING DENSITITES AND CIRCUIT COMPLEXITY; TO ENABLE DESIGNERS TO RAPIDLY CREATE AND COMPARE ALTERNATIVE DESIGN CONCEPTS; TO ELIMINATE MULTIPLE RE-DESIGN CYCLES; AND TO ENABLE REUSE OF PRIOR DESIGN KNOWLEDGE. THERE ARE NO CAE TOOLS COMMERCIALLY A ...
