Physical Sciences Inc. (PSI) and its academic partner, the Rochester Institute of Technology (RIT), will continue to advance the capability of RIT"s DIRSIG hyperspectral scene simulation software to enable accurate prediction of LWIR reflectance characteristics of liquid-contaminated surfaces. DIRSIG reflectance model and software modifications will be implemented by RIT. In conjunction with RIT ...

The chloroperoxidase enzyme from the filamentous fungus Caldariomyces fumago has applications in industrial chemical synthesis and the detection and inactivation of chemical warfare agents. Chloroperoxidase is capable of regio- and enantioselective oxygenations and halogenations of organic substrates. When performed chemically, these reactions typically require aggressive reagents and reaction c ...

ABSTRACT: An experimental and computational effort is proposed to develop a data-driven experimentally-validated framework for analysis of plastically bonded energetic materials at meso and micro scales. A unique data-mining strategy and model reduction technology based on thermodynamics and manifold learning techniques and on nonlocal dispersive reduced order model will be devised. Reduced order ...

ABSTRACT: The damage and loss caused by attacks and security breaches have drawn attentions to develop secure and reliable systems for embedded systems. Compared to their desktop counterparts, embedded devices are facing more security challenges, such as the more possible physical access to a target device and more constrained computing environment (e.g., limited RAM and CPU power). Together, the ...

ABSTRACT:Over half of spacecraft system anomalies attributed to interactions with the natural space environment including - electron upsets, damage to components, power system debilities, and complete satellite failures - are attributed to spacecraft charging.While measurements of electron emission, surface potential, and electrostatic breakdown provide important information, the great need for ma ...

Bridger Photonics, Inc. and the University of Arizona have successfully demonstrated a Phase I dynamically programmable multi-band compressive imaging system. The team demonstrated three key technical concepts that prove the feasibility of this powerful technology: 1. Advanced algorithms were used to develop compressive measurement basis sets for imaging and target classification. The algorithms ...

Microwave technologies have found a broad range of and growing applications, especially in the area of communications. Many microwave tunable devices are bulky and incompatible with RF semiconductor IC technology. The slow tuning response speeds, high material losses, and device noise at higher frequencies have also limited their widespread applications.Recent advances in processing complex oxide ...

Many military applications require efficient optical sources producing several to hundred watts in continuous-wave (CW) or quasi-continuous-wave (QCW) operation at room temperature (RT) in the MWIR (3-5 micron) and LWIR (8-12 micron) regions. While QCLs have become the sources of choice in these spectral regions, the only realistic option to attain hundred-watt power level with good beam quality i ...

ABSTRACT: In Phase II, major focus will be directed to the performance optimization and scale-up fabrication demonstration of the heterogeneously structured carbon fiber reinforced polymers (CFRP) with high through-thickness thermal conductivity for thermal management applications. The major research and development activities are: 1. Surface treatment study of nano- and micro-scale conductive f ...

ABSTRACT: Optical refrigeration is currently the only demonstrated all-solid-state cryocooling technology. Optical cryocoolers are devices that use laser light to cool small crystal or glass cooling elements. The cooling element absorbs the laser light and reradiates it at higher energy, an example of anti-Stokes fluorescence. The difference between the energy of the outgoing and incoming light c ...
