ABSTRACT: Space superiority needs protected tactical space communications with dynamic spectrum sharing, routing adaptation and interference mitigations against kinetic and non kinetic threats. The main focus of this project is to develop game-theoretic analytics and frameworks to support the Air Forces autonomy science & technology strategy (e.g., "deterrence" posture which in turn may be enabled ...

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: 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: Wireless communications, radar, and biological detection require electronic components operating in the mm-wave and THz frequency ranges. GaAs metal semiconductor field effect transistor and nanoscale CMOS technologies have demonstrated high frequency capabilities and will likely benefit from future material systems and device architectures. The cost of exploring this wide design space c ...

ABSTRACT: Enig Associates, Inc., a small business providing advanced modeling and simulation capabilities to the DoD and DoE, is proposing an innovative and novel electrical approach, using explosive-driven flux compression generators (FCG) to convert explosive chemical energy to electromagnetic energy with very high current output and superb energy conversion efficiency and then Joule heat light ...

ABSTRACT: In this project, IFT and its academic partner GMU developed an innovative Harness Enhanced Awareness for Radio Systems (HEARS) framework and technical underpinnings for DSA systems operating under conditions of imperfect knowledge, and used the framework to address challenging problems in satellite communication (SATCOM)DSA. As the logical core of the HEARS, Multi-Entity Bayesian Network ...

ABSTRACT: The need for improved performance of liquid rocket engines requires efficient wall cooling technologies to mitigate high heat fluxes from hot combustion gases to the engine wall in the thrust chamber. High heat fluxes to the chamber liners can be overcome by fuel film cooling (FFC) of the inside chamber using the liquid propellant. Moreover, the thermal cracking of the fuel creates coke ...

ABSTRACT: The hydrocarbon-fueled scramjet is capable of providing hypersonic air-breathing propulsion for high-speed applications. The effective operation of high-speed air-breathing engines (ram- and scram-jets) over a wide range of flow parameters (velocity and altitude) is one of the most technically difficult challenges in the design of hypersonic vehicles. The most promising approach to overc ...

ABSTRACT: To maintain superiority in the battle domains of space, ground, air and sea, it is natural that the U.S. move toward incorporating autonomous capabilities to enhance/replace the traditional role of humans. Continued advances in processing capability and techniques to employ decision logic and adaptive learning strategies will soon make this vision reality. To deploy any such capability o ...

ABSTRACT: Speech recognition technology is in wide use today and has been successfully integrated in a number of applications. Most of these applications require a microphone located near the talker. However, when a distant microphone is used where the speaker is at some distance from the microphone as in a hands-free communication, or in a meeting room, there is a major problem with the captured ...
