There are many challenges in addressing the problem of Political Will. The first is developing a clear, complete, consensual definition of Political Will driven by both theory and field practice. But a larger challenge is deconstructing and unpacking the Political Science and Social Science concept of Political Will into its complex constituent elements in order to arrive at their computational, r ...

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 ...

This Phase II STTR project continues the development of two prior successful Phase I STTR projects aimed at developing surface-enhance Raman optical activity (ROA) on near-infrared tuned gold-coated nanoshells for the detection of chiral molecules, biological molecules and higher biological structures and organisms for applications in the areas of biological research, pharmaceutical development an ...

We propose to develop marketable codes which will: model the morphology of heterogeneous propellants (a packing code); calculate the thermal and mechanical properties of such a morphology or pack; simulate the combustion of the pack; predict the statistics of aluminum agglomeration on the burning pack surface; simulate the flight of these agglomerates through the chamber, after surface detachment, ...

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 ...
