High Order Parallel Iterative Method for Diffusion Equations

, 2009
In this paper, we consider the initial boundary value problems of 1D diffusion equations. Based on a high order absolutely stable implicit scheme, we first construct two saul'yev asymmetry iterative schemes, and then present a class of parallel ...

A Note on Splitting Errors for Advection-Reaction Equations [PDF]

, 1994
In this note we consider proper ways to combine numerical schemes for advective transport and nonlinear chemistry. Obvious combinations are obtained with splitting in a so-called fractional step approach.

POSITIVITY-PRESERVING FINITE DIFFERENCE WENO SCHEMES WITH CONSTRAINED TRANSPORT FOR IDEAL MAGNETOHYDRODYNAMIC EQUATIONS

, 2016
. In this paper, we utilize the maximum-principle-preserving flux limiting technique, originally designed for high order weighted essentially non-oscillatory (WENO) methods for scalar hyperbolic conservation laws, to develop a class of high order ...

Numerical modeling for the recovery of fine structures in PDE-based image denoising,” (submitted to Image and Vision Computing

, 2008
PDE-based image denoising processes often lead to significant loss of fine structures such as edges and textures. This article is concerned with numerical modeling for PDE-based denoising models that can preserve/recover fine structures in the restored ...
