Hierarchical Multiscale Modeling of Wavelet-Based Correlations

This paper presents a multiscale-based analysis of the statistical dependencies between the wavelet coefficients of random fields. In particular, in contrast to common decorrelated-coefficient models, we find that the correlation between wavelet scales can be surprisingly substantial, even across several scales. In this paper we investigate eight possible choices of statistical-interaction mode...

Nonlinear Approximation and Adaptive Techniques for Solving Elliptic Operator Equations Multiscale Wavelet Methods for Pdes

w I n t r o d u c t i o n Adaptive methods are an important tool for numerically solving elliptic equations. Their origins appear in the adaptive grid refinements in finite element methods. Heuristically, adaptive methods are effective when trying to recover solutions u which exhibit singularities. Much impetus to the theory of adaptive finite element methods was provided by the introduction M ...

Mathematical modeling of a fixed bed chromatographic reactor for Fischer Tropsch synthesis

In this research, Fischer Tropsch synthesis (FTS) has been modeled in the fixed bed chromatographic reactor for the first time by applying a rather complex dispersed plug flow model for fluid phase and linear driving force (LDF) model for adsorbent. Model equations are dynamic, multi-component, non-linear and heterogeneous including reaction and adsorption simultaneously Complex kinetics fo...
