Optimization and large scale computation of an entropy-based moment closure
1 We present computational advances and results in the implementation of an entropy-based 2 moment closure, MN , in the context of linear kinetic equations, with an emphasis on heteroge3 neous and large-scale computing platforms. Entropy-based closures are known in several cases 4 to yield more accurate results than closures based on standard spectral approximations, such as 5 PN , but the comp...

Title of dissertation: OPTIMIZATION TECHNIQUES FOR ENTROPY-BASED MOMENT MODELS OF LINEAR TRANSPORT Graham West Alldredge, Doctor of Philosophy, 2012 Dissertation directed by: Professor André Tits Department of Electrical and Computer Engineering Kinetic equations are used to model many physical phenomena, including gas dynamics, semiconductors, radiative transport, and more. However, high dimen...
متن کاملIterative computation of negative curvature directions in large scale optimization
In this paper we deal with the iterative computation of negative curvature directions of an objective function, within large scale optimization frameworks. In particular, suitable directions of negative curvature of the objective function represent an essential tool, to guarantee convergence to second order critical points. However, an “adequate” negative curvature direction is often required t...
متن کاملAn Efficient Data Replication Strategy in Large-Scale Data Grid Environments Based on Availability and Popularity
The data grid technology, which uses the scale of the Internet to solve storage limitation for the huge amount of data, has become one of the hot research topics. Recently, data replication strategies have been widely employed in distributed environment to copy frequently accessed data in suitable sites. The primary purposes are shortening distance of file transmission and achieving files from ...
متن کاملMaximum-entropy moment-closure for stochastic systems on networks
Moment-closure methods are popular tools to simplify the mathematical analysis of stochastic models defined on networks, in which high dimensional joint distributions are approximated (often by some heuristic argument) as functions of lower dimensional distributions. Whilst undoubtedly useful, several such methods suffer from issues of non-uniqueness and inconsistency. These problems are solved...
