Colorado Engineering, Inc., a small woman owned business, and the University of Colorado at Colorado Springs are teaming to develop a Stegi@work architecture for an extensible, distributed application that can be utilized to detect steganographic content in media files, alert the user, and either mitigate (destroy) the content if possible or quarantine the files as appropriate. The key distinguis ...

Low-power Hall thrusters offer potentially important advantages for certain military applications but issues of lifetime and efficiency degradation at lower powers are issues hindering its utilization. A factor impacting efficiency is that the state-of-the-art techniques for electron generation used for neutralization (such as hollow cathodes operating on the same propellant as the thruster) do n ...

Silicon is the dominant material for electronic devices, but basic material properties have limited its use for optical devices. Passive components such as waveguides, splitters and multiplexers have been demonstrated on silicon wafers. Most active photonic devices have been made with materials such as gallium arsenide that cannot be grown directly on silicon electronics. The development of act ...

We propose an unprecedented suite of Usability Engineering software tools to be built upon the conceptual foundation of Virginia Tech's User Action Framework (UAF). We will use K-A-T's proprietary Latent Semantic Analysis (LSA) methods and software tools to validate and refine the UAF. We will also use LSA as the underlying analysis engine for the software tools, which will provide support for pro ...

An innovative electromagnetic wave detection and measurement system based on broadband, non-intrusive, miniaturized electro-optic (EO) and magneto-optic (MO) sensors will be developed in order to evaluate the effects caused by short duration burst or pulsed EM waves incident on electronic circuits. Due to the compact size and non-metallic construction, the EO and MO sensors can be placed within cl ...

The work outlined in this proposal is directed toward the development of materials and fabrication processes for organic-based complementary circuits. New and improved n-channel (electron transporting) semiconductors will be synthesized and characterized at Northwestern University. These materials will possess a mobility of about 1 cm2/V-s and will be combined with p-channel FET materials such a ...

Colloid thruster technology continues to be attractive for spacecraft propulsion, since its specific impulse can be many times greater than even the best bi-propellant chemical rocket. However, the technology was abandoned in the 1970s due to low charge-to-mass ratios, which lead to excessively high voltages and large inert mass fractions. The recent advent of microelectromechanical systems (MEM ...

We will provide convenient and accurate time-domain modeling capabilities for electromagnetics (EM) in dielectric media with regions having oblique boundary conditions, specifically for devices exhibiting omnidirectional reflectivity. Omnidirectional reflectors, constructed with layers of dielectrics, reflect electromagnetic radiation with 100% efficiency for all incident angles and polarizations ...

Zolo Technologies and Stanford University propose to develop and demonstrate an innovative combustion sensor technology that employs tunable diode laser spectroscopy implemented in a novel way to diagnose the SCRAMJET flow field for ground test evaluation. The sensor will enable the end-user to detect and quantify non-uniformities in the spatial distribution of temperature and species concentrati ...

ABSTRACT: The next generation of hypersonic and reentry vehicles being designed for the Department of Defense (DoD) applications will require advanced Thermal Protection System (TPS). While new TPS shields are under development, a key difficulty is the ability to predict and diagnose TPS performance. ElectroDynamic Applications (EDA) has been developing an optical diagnosticfor use during testi ...
