The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a universal algorithm and software that will correct this problem by employing the Huygens'principl ...

Massive blood loss is the most common cause of death in potentially survivable battlefield casualties, yet no definitive medical innovations have been made for reducing these deaths in the past several decades. It is still highly impractical to carry large volumes of refrigerated blood into battle, and substantial research for developing blood substitutes and extending the durability and portabili ...

ABSTRACT: In this Phase I STTR project, we propose to demonstrate the feasibility of developing a low cost, compact, time-domain terahertz (TD-THz) spectrometer specifically for the characterization of semiconductor materials over a range of temperatures, electric fields, and magnetic fields. In phase I, we will configure fiber optic coupled TD-THz instrumentation to make measurements on a sampl ...

Gel propulsion systems combine the best characteristics of solid and liquid propellants. The gel system stores like solid propellant, but flows like a liquid when pressurized, enabling throttle and restart capability similar to liquid propellants. An enabling technology for the further advancement of gelled propulsion is the development of tools to render the development of propellant formulation ...

ABSTRACT: Optical Sciences Corporation (OSC) and the University of Alabama in Huntsville"s Center for Applied Optics (UAH/CAO) will demonstrate the feasibility and present a plan for developing optical instrumentation for the monitoring, mitigation, and removal of cryodeposits accumulated on optical and mechanical surfaces in cryogenic-vacuum radiometric calibration chambers. OSC will investigat ...

Significant recent research has shown that breath biomarkers are excellent indicators of oxidative stress caused by conditions ranging from radiation exposure to COPD. Current techniques for collection, concentration, and analysis of exhaled breath do not support real-time analysis, or require complex and bulky equipment. Streamline Automation, LLC will develop a portable Breath BioDetector in p ...

PowerTHRU Corporation proposes to meet or exceed the requirements of this STTR by utilizing its extensive experience in carbon fiber based high speed flywheel systems, to design and build a 100K RPM flywheel system. Unlike steel flywheel technologies that are limited by the speed in which they can safely rotate, PowerTHRU has already demonstrated that 50,000 RPM carbon fiber flywheels can be desig ...

Virtual EM Inc. proposes to develop STAP techniques using machine learning algorithms for eventual implementation in critical radar systems. These algorithms require less time to train than neural networks. Virtual EM's simulation packages will be used to train the algorithms for array element failure, multi-path and jamming mitigation as well as interference from ground and maritime clutter. The ...

Helmeted navy divers are exposed to high levels of noise from self-generated mechanisms, such as regulator exhaust, and external sources, such as underwater tool-generated noise. Noise exposure limits can be easily exceeded especially if effective communications through helmet-mounted speakers is required. A multi-faceted approach is proposed to reduce self-generated noise as well as overall helme ...

The desired outcome of this STTR project is the development of compact, stand-alone, economical, and rugged pulse shaper units that can be used to control chemical reactions, and have a wide range of applications based on molecular control for detection of chemical and biological threats, explosive, and toxic chemicals. In addition, these units will enable a broad range of fundamental studies. Dur ...
