Verification of the Guidance, Navigation and Control (GN&C) algorithms and software utilized onboard spacecraft is of paramount importance to ensure resilient, correct operation after launch. Rather than wait until the GN&C software has been deployed to perform on-orbit verification, offline verification integrated into the design process will improve mission performance, significantly reduce the ...

Radio frequency communications and sensors are everywhere in both personal and military life. RF fields are also used in some medical therapies. However, little is known about the medical effects that result from the routine exposure of tissue to RF fields. To understand such effects, new instrumentation is needed that can quantify the RF radiation amplitude with spatial resolution comparable to t ...

The Department of Defense relies on a worldwide network of radar and optical sites to maintain Space Situational Awareness.Although careful consideration during site selection process solves some of this mission's challenges, optical sensor imaging of objects at significant ranges is always hampered by many other factors, such as limited-aperture optics and atmospheric turbulence.There remains, ho ...

The development and implementation of new damage morphology models for concrete materials is critical to understanding their dynamic behavior during severe shock loading environments.Current constitutive models of conventional strength concretes do not accurately represent the behavioral characteristics of new ultra-high strength concretes because of differences in damage mechanisms during failure ...

J.T. McGraw and Associates,LLC,in collaboration with Purdue University, propose to demonstrate and test deployment of prototype COTS-derived optical SSA sensors designed to rapidly reconstitute and enhance global surveillance of GEO and near-GEO space.JTMA's advanced designs, techniques and algorithms allow small telescopes to achieve sensitivities very near those of larger traditional systems.Whe ...

The Atmospheric Pressure Plasma Jet (APPJr) technology invented at Los Alamos National Laboratory and exclusively licensed to APJeT, Inc., is a revolutionary platform technology enabling economic application of atmospheric pressure plasma technology in an array of applications. APPJr is a non-thermal, stable, uniform discharge having 50-1000 times greater power density than other atmospheric plasm ...

Multiple scale simulations are among the most challenging calculations in scientific computation, yet this capability is critical to realizing a virtual prototyping capability for devices based on electromagnetic and plasma technology. One solution to multi-scale problems is the renormalization group (RNG), which offers a systematic means to investigate and couple the impact of mutiple scales tog ...

When designing distributed systems, it is necessary to compare two or more designs of the models of the system. By developing formal methods theory to automate the process of checking for differences, multiple designs can be quickly compared to come up with the best design of the system. UIUC has done research on an algorithm called Circular coinduction to automatically discover bisimulation relat ...

Southwest Sciences Inc., in collaboration with the University of Texas, propose to develop a versatile multipass cell for optical absorption and spontaneous Raman measurements of flames. This new design will achieve over 100 passes with a tight central spatial footprint for Raman studies as well as be fully configurable for differing working distances and laser sources.

This Phase I STTR project will demonstrate that classical force fields can be developed from first principles and used to quantitatively predict the thermodynamic and transport properties of ionic liquids. The project will initially focus on three ionic liquids of interest to the Air Force: 1-n-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide or [hmim][Tf2N]; 2-hydroxyethylhydrazinium ...
