Computer wargames and combat simulation software has reached a very high level of comprehensiveness and sophistication in terms of modeling fidelity and accurate results. The recently released simulation titled Point of Attack-2, in particular, affords users a very powerful combat simulation package in a desktop PC environment. At the same time, however, the increased complexity of the system ma ...

This project proposes to design and build an advanced evanescent velocity sensor for near wall velocity measurements in microfluidic devices. Optical MEMS technology will be utilized to create a compact sensor design. The sensor will measure velocities within 100 nm of the channel wall, which is five times closer than the best current technique. The sensor will have a spatial resolution of 100 nm ...

All-nitrogen compounds, also known as polynitrogen compounds, or nitrogen-rich compounds, such as polyazides, store large amounts of energy that can be released when these materials decompose to molecular nitrogen. The synthesis of these materials is very challenging because the reactants, intermediates, and desired products have high endothermicities. These high endothermicities make many of the ...

ABSTRACT: A range segment upgrade for Air Force satellite control network (AFSCN) will significantly improve system effectiveness via spectrum sharing and seamless interoperation. However, the upgraded system requires new capabilities such as real-time and accurate RF interference detection and mitigation, array antenna backlobe/sidelobe suppressions, accurate performance degradation prediction, ...
