ABSTRACT: This Phase I effort will involve the development of an ultra low cost, high specific power, modular and flexible solar array module using currently available thin-film solar cells, innovative interconnects, and flexible encapsulation. The high efficiency thin-film solar cells will enable high specific power and flexibility in the module. The interconnect scheme and encapsulation will a ...

ABSTRACT: The ability of plasmas to modify combustion has been known for more than 50 years. Recent advances in plasma generation technology and measurement diagnostics have led to extensive efforts to understand both the kinetics of the plasma-flame interaction and the enhancement of combustion properties such as ignition, extinction, flame speed and dynamics. Combustion Science & Engineering, ...

ABSTRACT: Ramjets and scramjets are the preferred propulsion platforms for flight in the supersonic (3

ABSTRACT: This Small Business Technology Transfer Phase I project develops collaborative spectrum awareness techniques that enable dynamic spectrum access (DSA) systems to make decisions with imperfect awareness. DSA technologies are emerging as a promising mitigator against spectrum congestion resulting from the explosive growth in commercial and Government wireless systems and services. DSA sys ...

ABSTRACT: Intelligent Automation Inc. proposes to design a robust decision making and dynamic spectrum access (DSA) system for satellite communications under uncertainty. Our system integrates various types of uncertainty caused by environment, regulation, uncontrollable user effects, and prediction. We will first develop methods to quantify the uncertainty by either individual observation or col ...

ABSTRACT: Advances in large scale visual sensors enable (near) real time acquisition of imagery data over wide urban surveillance areas. Data collected by such sensors, such as the wide area motion imagery (WAMI) systems, however poses computational challenges to existing visual analysis algorithms. Among many tasks, tracking multiple moving target indicators (MTI) is of fundamental importance si ...

ABSTRACT: We propose a comprehensive Risk Assessment of Disclosure via Automated Reasoning (RADAR) system. This system will leverage and advance various theoretical models in statistical inference (e.g., probe selection and posterior estimation) and information theory (e.g., entropy approach) to obtain a set of analytical tools for information disclosure analysis. These tools are integrated into ...

The overall project objective is to develop and demonstrate a software package based on Fermi kinetics charge transport and Delaunay/Voronoi field discretization that accurately predicts semiconductor device behavior from DC up through the mm-wave and TH...

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: 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 ...
