ABSTRACT:The proposed system design provides a capability to collect target signatures faster, and at more aspect angles from a locus of points on a hemisphere centered on the target. State of the art communications channels are used to transmit radiometric infrared data to remote data recorders. Payload positioning may be done by manual or pre-programmed control with precision GPS and inertial se ...

ABSTRACT:The overall goal of the project is to develop reliable reduced order modeling technologies to automatically generate parameter-varying aerothermoservoelastic (ATSE) reduced-order models (ROMs) for fast Fluid-Thermal-Structural Interactions (FTSI) assessment and control system design. The Phase I effort will focus on developing several key components, including parameter-varying formulatio ...

ABSTRACT: Designing an efficient and effective film cooling system to protect critical components of modern rocket engines requires a significant number of challenges to be addressed. Complicating the already difficult hydrodynamic challenges, thermal cracking of hydrocarbon fuels is always accompanied by coke formation. The coke deposits on the combustor and nozzle walls reduces heat fluxes and c ...

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 ...

We will evaluate a novel warming method, developed by our collaborator John Bischof, that promises solution of one of the remaining barriers for banking of large organs and vascularized composite tissues. The method involves radiofrequency and magnetic nanoparticles to obtain rapid uniform electromagnetic rewarming of biological materials instead of warming from the outer boundary using convection ...

Trauma is the leading cause of death in civilian and military environments and acute hemorrhage contributes to a large portion of these fatalities. Recent experience from Iraq and Afghanistan has demonstrated the crucial role of blood products in the care of critically injured soldiers. Unlike plasma and red blood cells, which can be cold stored for longer time periods, platelets can be safely sto ...

The long term goal of the proposed research is to develop improved methods for cryopreservation of complex tissues at extreme low temperature. An innovative approach is taken in the proposed line of research, where synthetic ice modulators (SIMs) are combined with established cryoprotective agent (CPA) cocktails to create more favorable conditions for cryopreservation in a process known as vitrifi ...

Current methods for stem cell isolation are time-consuming, costly, and labor-intensive, and ill-suited for point of care applications. To overcome these limitations, we propose to develop and demonstrate a high-throughput, non-invasive, microfluidic stem cell analyzer to enable a rapid isolation of high-quality stem cell products from clinically relevant samples. Our technology enables significan ...

Historically, the porosity associated with ceramic matrix composite structures has been viewed as a detriment for many missile applications. The standard practice is to perform several treatment/retreatment processes to reduce the porosity to an acceptable level while increasing the strength of the structure. The processing methods inherent to the production of many composite materials may provide ...
