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

open access: yes, 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 ...

A Basic Mathematical and Numerical Model for Gas Injection

open access: yes, 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.

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

open access: yes, 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.

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

open access: yes, 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 ...

Linear Partial Differential Algebraic Equations - Part II: Numerical Solution

open access: yes, 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 ...
