This project address the fabrication of solar blind detectors from the MgZnO material system. Both MBE and MOCVD material growth techniques will be used for deposition of the required material layers. Simulation software we be used to aid in the design of the photodetector structure. Devices will be fabricated from the grown structures and their electrical and optical characteristics determined.

ABSTRACT: High-performance organic electro-optic (OEO) polymers can enable the development of advanced EO technologies for achieving significantly reduced energy consumption and bandwidth enhancement in future information and communication technologies. One of the most critical steps in developing successful photonic technologies is to have high quality, reproducible materials that can be availab ...

ABSTRACT: State of the art Orbital Transfer Vehicle systems and GEO transfer missions require the demanding combined requirements of both high Thrust-to-Power (greater than 150 mN/kW) and high specific impulse (greater than 3000 s), all at constant power. The 9 kW PROTEAN system is a two-stage plasmoid thruster which adds secondary Neutral Entrainment (NE) to the ElectroMagnetic Plasmoid Thruster ...

We propose a rapid mapping and 3-D visualization system especially suited for inside buildings, tunnels, urban canyons, and other environments where GPS may be poor or not available. The system--which was fully demonstrated in our Phase I effort-- includes mobile Sensor Nodes that wirelessly supply compressed 3D range data and color imagery to a central Fusion Node. The Fusion Node runs 3D recon ...

A vaccine to protect against diseases resulting from infection with Streptococcus pyogenes is under development. This vaccine utilizes a recombinant fusion protein (SpeAB) comprising of genetically detoxified SpeA, a secreted toxin, and SpeB, a surface bound and secreted cysteine protease. During phase I investigations a lead vaccine formulation was determined by optimization of critical paramet ...

ABSTRACT: The chalcogenide based ion-conducting memristor has been shown to be an effective element as the core of a simple neuromorphic computing circuit. The response of the computing circuit is the result of weighted external stimuli, the current state of the device, and the history of exposure by the device to the stimuli. A highly specialized version of the device, as developed by the Advanc ...

ABSTRACT: Thermospheric densities are critical in determining orbital drag for providing collision avoidance warnings for manned and unmanned spaceflight, accurately cataloging orbiting objects, predicting reentry times, and estimating satellite lifetimes, on-board fuel requirements, and attitude dynamics. One of the critical drivers to thermospheric density models is the extreme ultraviolet (EUV ...

A parallel random number generation suite that generates, dynamically, millions of parallel pseduorandom number streams suitable for consumption by high performance computing (HPC) applications on various platforms will be implemented, tested, and provided to Government, academic and private HPC users for their evaluation and use. The software will be tuned for scalability, repeatability and effic ...

ABSTRACT: Due to scarcity of spectrum, Dynamic Spectrum Access (DSA) becomes a needed technology to improve the utilization of electromagnetic spectrum for DoD satellite communication. However, current DSA approaches are developed for terrestrial communications without addressing the unique challenges for SATCOM environments such as error-prone spectrum sensing, high mobility, and large coverage. ...

ABSTRACT: Coordinating and sharing information across multi-level security (MLS) networks are of great interest in many military applications. However, it is very challenging to accomplish those goals due to the heterogeneous security classifications of different network domains. The recent proposed cross-domain solutions (CDS) provide initial steps to make such applications possible. However, th ...
