A Basic Mathematical and Numerical Model for Gas Injection

, 1996
In this paper we discuss a mathematical model for gas storage processes. In addition we outline an approach for numerical simulations. The focus is on model assumptions and limitations with respect to the software to be developed.

CHA & KIM: EDGE-FORMING METHODS FOR COLOR IMAGE ZOOMING 1 Edge-Forming Methods for Image Zooming: Color Images

, 2008
This article introduces edge-forming schemes for image zooming of color images by general magnification factors. In order to remove/reduce artifacts arising in image interpolation such as image blur and the checkerboard effect, an edge-forming method is ...

The error analysis of Crank-Nicolson-type difference scheme for fractional subdiffusion equation with spatially variable coefficient

, 2017
A Crank-Nicolson-type difference scheme is presented for the spatial variable coefficient subdiffusion equation with Riemann-Liouville fractional derivative. The truncation errors in temporal and spatial directions are analyzed rigorously.

Linear Partial Differential Algebraic Equations - Part II: Numerical Solution

, 1997
. We consider the numerical solution of linear partial differential algebraic equations (PDAEs) of the general type Au t (t; x) +Bu xx (t; x) +Cu(t; x) = f(t; x) (where A; B; C are constant (n \Theta n)\Gammamatrices) by means of the method of lines ...

A Well-Balanced Scheme Using Non-Conservative Products Designed for Hyperbolic Systems of Conservation Laws With Source Terms

, 2001
The aim of this paper is to present a new kind of numerical processing for hyperbolic systems of conservation laws with source terms. This is achieved by means of a non-conservative reformulation of the zero-order terms of the right-hand-side of the ...

Convergence Of The Operator-Difference Scheme To Generalized Solutions Of A Coupled Field Theory Problem

, 1997
In this paper the operator-difference scheme for the numerical solution of a problem arising from coupled field theory is thoroughly investigated for the case when the classical assumptions of sufficient smoothness cannot be applied.
