Partial Differential Equations (PDEs) are at the core of Air Force scientific priorities in air vehicle design. The goal of this STTR is to provide unprecedent computational power to the solution of large-scale PDE problems in 3D through the use of reconfigurable computing linear equation solvers based on iterative methods. The result of this research will be packaged in a system that, by the e ...

This STTR phase II proposal addresses AFOSR's task to: "Develop seamless, easy to use, efficient code to calculate electronic wave functions and potential energy surfaces of molecules and predict kinetic rate constants for reactions a priori." This is a long-unsolved problem, fundamental to chemistry, where quantum chemical methods must be extremely accurate to yield reliable rate constants. Yet u ...

The conceptual design of a novel, hypersonic electromagnetic launch system has been developed. Phase-1 assumed a 100-kg projectile leaving the launcher at 7,000 m/sec. The projectile is propelled and levitated by electromagnetic forces inside a tube filled with low pressure helium. A controlled acceleration profile, fully adjustable to the requirements of various missions, is used to reach 5000 ge ...

DESCRIPTION (provided by applicant): Informed consent has become an essential component of the doctor-patient interaction. The informed consent process requires that patients not only be given information about proposed medical treatment, but that it be presented in an understandable way so the patient can make meaningful choices about medical alternatives. At the heart of the inf ...

DESCRIPTION (provided by applicant): Every year in the US, several million people suffer serious peripheral nerve injury. Injuries to the peripheral nervous system (PNS) are a major source of disability, impairing the ability to move muscles or to feel normal sensations. To treat these problems, more than one million procedures were performed in the US in 2002, totaling more than $10 billion in me ...

DESCRIPTION (provided by applicant): Modulation of the inflammatory cascade by several diverse strategies including A immunization, non-steroidal anti-inflammatory drug (NSAID) administration, and manipulation of microglial activation states have all been shown to reduce Alzheimer disease (AD)-like pathology, and cognitive deficits in AD transgenic mouse models. Our recent study demonstrated ameli ...

The objective of this proposal is to demonstrate the feasibility of a quantitative dynamical model of human attention and perception. Recent experimental findings have demonstrated the importance of event timing for perceiving and attending to complex sequences of events: 1) The auditory system uses active temporal mechanisms for analysis of sound from the earliest stages of sensation through the ...

The development of tractable mathematical models of gradient-frequency nonlinear resonator networks is critical to advanced computer applications that require faithful computer simulation of human attention and/or perception. Conventional linear resonator models are computationally and analytically tractable, however tractability is achieved at the expense of capturing many significant features of ...

We propose to use nano-structured Silicon photonic crystal fiber to convert near infrared (NIR) to Mid infrared using parametric amplification. Silicon has intrinsic properties that lend itself to this application. Silicon has very low loss in the Mid IR, high damage threshold, and high environmental stability. However, NIR pumps experience strong loss in bulk silicon crystal due to two-photon ...

An innovative methodology, based on mechanistic models, will be developed for prediction of long-term (25+ years) durability of composites for the US Army's emerging facilities in different climatic zones. Accelerated testing simulating the Army's composites applications in various constructions and fields will validate it. Phase I developed the basic predictive tool using the Arrehenius principle ...
