The Air Force is interested in developing technology that would enable long duration hypersonic flight with reusable aircraft. Hypersonic flow presents many design challenges that can be encapsulated into an aerothermoelastic problem, i.e., a complex dyn...

ABSTRACT: We propose here a robust production-level high-order mesh generation software for complex geometries. High order accurate numerical methods are becoming increasingly popular in the present time and have demonstrated a great measure of success in efficient error-controlled simulations for a wide variety of important problems. A curved geometry and mesh generation system is essential in m ...

In this program, HyPerComp and University of Michigan have teamedtogether to develop a high-order grid generator for Euler and viscousmeshes. The grid generator is based on HyPerComps successful generalpurpose CAD2Mesh software and is being integrated with HyPerCompsHDphysics and U. Michigans XFlow DG high-order solvers. High-order gridgeneration methods are being implemented to accurately capture ...

ABSTRACT: XL Scientific LLC will leverage over a half a century of High Power Microwave (HPM) Effects Test and Modeling experience to develop an integrated DREAM2 toolkit that models the vulnerability and susceptibility of electronic systems, subsystems and components to directed energy (DE) HPM weapons. The analysis toolkit developed will center on three essential modules, critical in a full asse ...

ABSTRACT: The sensor system requirements for image based navigation that uses passive millimeter wave imaging radiometry will be established based on existing RelNav and AbsNav algorithms that were demonstrated to work in multi-modal imagery. Existing flight data will be used to simulate the PMMW imagery for these tests. A preliminary design of such a PMMW system will be created. Under Phase-II th ...

ABSTRACT: The focus of this research will be on developing a model and associated computational tool called HPEM-Expert that is consistent with the Directed RF Energy Assessment Model 2, (DREAM2), which describes and predicts the effects of a high-power electromagnetic (HPEM) signal on a mobile target, to improve on the existing DREAM tool. Our approach will be to develop a modeling and simulation ...

ABSTRACT: Our goal is to develop theoretical frameworks for efficient multisensor fusion of high dimensional data for target detection localization and tracking. We plan to develop novel algorithms based upon our previous research on copula theory to perform inference with multi-modal correlated sensor data. Copulas describes the dependence between random variables and allow one to optimally explo ...

ABSTRACT: In this effort selected SBIR technologies will be matured and merged to establish the Adaptive Cyber-secure Cross-layer Communications-Classification System (AC4S) for enhancing the throughput, spectral efficiency, speed, reliability and security performance of software defined radio (SDR) communication networks. One of the core technologies in the AC4S architecture is the Cyber Superior ...

Novel algorithms were developed for ecient multi-sensor fusion of correlated high-dimensional data to support target detection. In our compressive sensing framework, high-dimensional data is compressed using low dimensional random projection matrices. When the high-dimensional data exhibits low-dimensional structures, this scheme is capable of capturing all the significant informative with fewer r ...
