Accelerators used for nuclear-physics research require megawatts of radio-frequency energy. They currently employ vacuum-tube power amplifiers or conventional solid-state amplifiers that are inefficient and therefore consume a great deal of prime power. Many other applications including semiconductor processing, cellular-telephone base station transmitters and military communication systems simila ...

Conventional indoor environmental monitoring technologies are expensive, cumbersome to install and maintain, and do not provide the distributed granularity required to capture the necessary details for efficient energy management of commercial buildings. Developments in wireless sensor networks (WSN) provide substantial framework for monitoring and addressing indoor environments at scale. However ...

TiER1 Performance Solutions proposes to develop CATS (Competency-based Adaptive Training System), a system to address common warfighter training needs in the Air and Space Operations Center. A major goal of this effort is to prepare warfighters for mission readiness by integrating a Learning Management System (LMS), which delivers personalized content and learning events as needed and provides con ...

ABSTRACT: A need exists for a reliable, low cost radiation-hardened, non-volatile (NV) memory in aerospace and defense applications and in reliable, long-life, high-speed NV memory for terrestrial and commercial applications. Present offerings can accomplish the objective, but only at the expense of performance, power, size, and weight. Recent refocus on magnetic memory technologies, stemming f ...

ABSTRACT: A need exists for a reliable, low cost radiation-hardened digital memory in aerospace and defense applications and in long-life, high-speed memory for terrestrial and commercial applications. Present offerings can accomplish the objective, but only at the expense of performance, power, size, and weight with device redundancy and shielding. Recent focus on Graphene and its capabilities ...

ABSTRACT: Structural monitoring of the landing gear of fixed and rotary wing aircraft is of critical importance to the Air Force. These structures are subjected to repeated large dynamic loads that are highly variable in nature. In order to track these structures"fatigue over time, the magnitude and direction of load events and the number of fatigue cycles must be recorded. Smart, embedded mult ...

ABSTRACT: nGimat proposes to develop a novel technique to sinter ceramic films deposited onto metallic substrates by combining two efficient and inexpensive techniques: flame sintering and field-assisted"flash"sintering. The creativeness of this approach lies in the concept to use a flame as both a heat source and a conductive medium. Compared to conventional thermal sintering, this new techniq ...

ABSTRACT: Cavitation which leads to head falloff and feed system instabilities are a constant source of problems for the low net positive suction head (NPSH) pumps that are needed for advanced liquid rocket engines. Head falloff limits the pumps capability to deliver propellant at the required pressure and cavitation induced instabilities are a significant source of structural failures in rocket ...

Military network environments will be subject to both internal and external threats for the foreseeable future. Internal threats to cyber networks from U.S. personnel receive little attention in comparison to external threats; yet, the consequences can be even more devastating. The lack of tools for understanding insider threat, analyzing risk mitigation alternatives, and communicating results e ...
