ABSTRACT: In this proposal, a team comprising ParaSim Inc. and the University of Utah will examine the feasibility of generating curved high-order meshes from hybrid linear meshes while retaining a given boundary geometry. Specifically, a preliminary design of a software package for creating high-order (up to 4th order and higher) hybrid-element meshes for complex geometries will be developed. S ...

ABSTRACT: This project will develop and demonstrate a software package based on coupled Fokker-Planck (FP) - Fermi Kinetic Transport (FKT) models and full-wave Maxwell electromagnetic (EM) solver to accurately predict semiconductor device behavior from dc up through the mm-wave and THz frequency ranges. The FP model provides accurate non-equilibrium occupation functions for hot electrons with real ...

ABSTRACT: Over the past decade, there has been a sustained interest in Global Positioning System (GPS) denied navigation technologies for unmanned aircraft systems (UAS). This has been primarily due to the well accepted susceptibility of GPS signals to intentional jamming or unintentional interference and blockage. One of the challenging problems in GPS-denied navigation is handing off moving targ ...

ABSTRACT: Analysis and Applications and Associates, Inc. (AAA) proposes to develop software that evaluates effects of the hypersonic flow environment on electro-optic/infrared optical systems and vehicles for specific hypersonic flight profiles. We propose a high fidelity definition of the near-field flow, using the latest CFD and turbulence modeling technologies, to determine the environment from ...

ABSTRACT: Toyon Research Corp. and the Penn State Univ. propose research and development of innovative algorithms for classifying objects and activities observed in high-dimensional data, including video and hyperspectral imagery. The proposed algorithms include novel feature clustering techniques to enable effective characterization of intra-class and inter-class appearance variations in datasets ...

ABSTRACT: A platform (PHA-fuse) for the stabilization of diagnostic and therapeutic reagents will be established based upon the polymer, polyhydroxyalkanoate (PHA). Fusions of a target molecule to PHA synthase, the enzyme responsible for PHA synthesis, will be constructed and used to catalyze the synthesis of PHA granules. These PHA granules will help stabilize the fused target molecules and elimi ...

ABSTRACT: Future corrosion and wear protection of structural metals on on military aircraft and weapon systems will require advanced development of metallic and composite materials that are not restricted with respect to environment, safety and occupational health regulations. Conventional metallic alloys containing chromium, nickel, cobalt, and tungsten that have historically provided coating pro ...

Experimental data from a number of DoD supported research programs have indicated that electrical systems capable of producing highly repetitive bursts of high voltage, fast risetime pulses are a critical enabling technology for applications tied to nonequilibrium physical processes, such as combustion, boundary layer flow, and the generation of high power EM waves. Recognizing the important role ...

ABSTRACT: MZA partnered with the University of Notre Dame proposes to extend MZAs WaveTrain wave-optics sensor simulation framework to model EO/IR sensors operating on hypersonic aircraft. Following the methods we have developed for aero-optical imaging through subsonic, transonic, and supersonic flows, existing WaveTrain libraries will be expanded to include hypersonic flow, shocks, thermal effec ...

ABSTRACT: Hypersonic vehicles will require structures that can withstand highly transient flows and complex loadings throughout the flight trajectory. Shock boundary-layer interaction can excite panels locally and lead to structural failures. Non-contacting measurement technologies are needed to characterize the effect of flow transients (due to pressure and temperature fluctuations) on the struct ...
