To advance scientific and medical understanding of blood chemistry, we propose to develop modern medical simulation software that will be of use in predicting outcomes of medical interventions. For example, the chemical reactions between hemoglobin, oxygen, carbon dioxide, and electrolytes that occur in blood are essential to understanding human physiology, but still confuse students at many leve ...

This Small Business Innovation Research Phase I project proposes a coupled Navier Stokes/Full Potential (NS/FPE) solution methodology for the study of unsteady flow analyses of next-generation helicopter airfoils. The principle behind NS/FPE approach is to divide the physical space being solved into an inner viscous zone near the body surface, and an outer wake zone away from the surface. The Na ...

A quality simulation which allows a user to simulate the acoustic emissions in a multi-source environment and then study the effects these conditions have on a set of acoustic sensors would be of great value. As acoustic sensors technology continues to advance with robust algorithms for detection, tracking and identification as well as high performance hardware providing real-time operation, thes ...

Large-scale scientific and engineering simulations currently being performed on high-end parallel computers have exceeded the capabilities of present visualization systems. The proposed system utilizes distributed object technologies (OMG CORBA) to perform parallel, distributed visualization of large computational problems, like computational fluid dynamics and structural dynamics. Distributed a ...

This project applies a combination of Artificial Neural Networks (ANN), Genetic Algorithms (GA), and CAD software to the problem of optimum armor design. Previous work for TACOM has established the efficacy of ANN/GA as applied to the problem of 1-D armor design. This new work will extend the concept to full 3-D vehicle geometries (CAD models). The CAD part of the code will handle the 3D data d ...

We propose the development of a pIezoelectric pressure transducer to be used in diesel engines for machine health monitoring and inclusion in an engine combustion control system. Reliability, accuracy. and affordability are the focus of this research since these issues remain the most difficult to overcome for the development of a cost effective pressure transducer. Manutacturing costs of $5.00 ...

The program objective is to demonstrate enhanced antenna element gain enhancement for small light weight synthesized virtual antennas. Astron/VPI have proposed a series of innovative helicalantennas to support the improved performance of a multi-element synthesized virtual antenna.

The complexities of barrel erosion are manifested in thermal, mechanical, and chemical interactions. Gun tubes made from refractory metals have excellent barrel erosion resistance, but are costly to manufacture. A need exists for an economical technique to line gun barrels with erosion and wear resistant materials. TPL will demonstrate a three unit operation process for cladding liners into gun ...
