DESCRIPTION (provided by applicant): Circulatory, hypoxemic or traumatic arrest claims an estimated 350,000 lives per year in the United States accounting for almost 15% of all deaths. Circulatory, hypoxemic, or traumatic arrests result in whole-body ischemia, most significantly global cerebral ischemia. Brain cells die when they no longer receive oxygen and nutrients from the blood. Because cereb ...

76023-Among the contributors to atmospheric pollution, carboxylic acids (including mono- and dicarboxylic acids, aliphatic ketoacids, and aromatic acids) are an important class of oxygenated, organic compounds in atmospheric aerosols. To better understand their sources and atmospheric transformation processes, an automated method for measuring their concentration is required. This project will d ...

Combustion instability, or screech, occurs in many modern gas turbine systems, and is due to the complex physical coupling of the acoustic resonances in the combustion chamber with fluctuations in the heat release of the combustion process. These instabilities can produce large pressure fluctuations that can be severe enough to damage engine hardware. Next-generation gas turbines will increase the ...

Active imaging systems are used to for imaging in degraded visual environments like that found in marine fog and other environments with a high level of attenuation and scattering from obscurants like fog, rain, smoke, and dust.These systems are still limited in range and resolution. SA Photonics is taking advantage of multiple image enhancement techniques, like wavelength tunability, pulse contro ...

The development of adaptive AI technology is vital to the creation of simulation technology with predictive capabilities. The objective of this research project is to deliver an adaptive AI-based simulation technology with predictive capabilities that will enable a family of operational-level tools and simulations that can propose and assess realistic and emergent adversarial behavior, automate th ...

Filamentation of ultra-short laser pulse propagation in non-linear media offers significant potentials allowing to address numerous problems in military and commercial sectors. However, practical implementation of this requires an ability to control the USLP at its propagation through inhomogeneous media, like turbulent atmosphere. On the basis of our approach for combating turbulence effects on p ...

This proposal is to extend into Phase II our development of a new system for Adaptive Visualization of Social Networks (ADVIS). Recent years have seen a dramatic increase in the collection and study of social network data. Numerous social network visualizations have been developed to support user exploration and understanding of these data. However even in the few best systems, cognitive and de ...

The Department of the Navy has a need for the development of an additive manufacturing (AM) process for key vacuum electronic device components to meet on-demand, flexible, and affordable manufacturing requirements. The goal of this Phase II effort is to develop and validate Electron Beam Melting (EBM) additive manufacturing (AM) technology for the production of vacuum electronic devices meeting t ...

The Department of Defense (DoD) has a demand for out-of-production parts to maintain mission readiness of various weapons platforms. Additive manufacturing (AM) is an exciting and promising manufacturing technique that can make out-of-production parts and holds the potential to solve supply chain issues, such as high costs (i.e. for low-volume parts) and sole sourcing risks. The ability of AM to s ...

The understanding of how fuel evaporates and mixes when injected into an engine cylinder is of key importance for the design of cleaner, more efficient vehicles. To meet the Department of Energy & apos;s goals of improving fuel efficiency in gasoline engines by 25 percent and diesel engines by 40 percent, advanced tools for research on fuel injection dynamics are needed. Existing techniques for in ...
