VAGO method for the solution of elliptic second-order boundary value problems [PDF]

open access: yes, 2010
Mathematical physics problems are often formulated using differential oprators of vector analysis - invariant operators of first order, namely, divergence, gradient and rotor operators.

A Mixed‐Culture Model of a Probiotic Biofilm Control System

open access: yesComputational and Mathematical Methods in Medicine, Volume 11, Issue 2, Page 99-118, 2010., 2010
We present a mathematical model and computer simulations for the control of a pathogenic biofilm by a probiotic biofilm. This is a substantial extension of a previous model of control of a pathogenic biofilm by microbial control agents that are suspended in the aqueous bulk phase (H. Khassehkhan and H.J. Eberl, Comp. Math. Meth.

A numerical study of effects of the axial stress on unsteady liquid pipeline flows

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 15, Page 777-788, 2004., 2004
We study the effects of the axial component of the shear stress on unsteady pipeline flows. We show that the axial component of the shear stress should be introduced in the modeling of unsteady flows, and as a numerical model, we propose a one‐dimensional momentum equation in which a term containing the second derivative of the velocity with respect to

An efficient approach for solving a class of nonlinear 2D parabolic PDEs

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 17, Page 881-899, 2004., 2004
We consider a class of nonlinear 2D parabolic equations that allow for an efficient application of an operator splitting technique and a suitable linearization of the discretized problem. We apply our scheme to study the finite extinction phenomenon for the porous‐medium equation with strong absorption.

Asymptotic and numerical solutions for diffusion models for compounded risk reserves with dividend payments

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 14, Page 721-739, 2004., 2004
We study a family of diffusion models for compounded risk reserves which account for the investment income earned and for the inflation experienced on claim amounts. We are interested in the models in which the dividend payments are paid from the risk reserves.

Approximate solution for Euler equations of stratified water via numerical solution of coupled KdV system

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 63, Page 3979-3993, 2003., 2003
We consider Euler equations with stratified background state that is valid for internal water waves. The solution of the initial‐boundary problem for Boussinesq approximation in the waveguide mode is presented in terms of the stream function. The orthogonal eigenfunctions describe a vertical shape of the internal wave modes and satisfy a Sturm ...

A new compact finite difference quasilinearization method for nonlinear evolution partial differential equations

open access: yesOpen Mathematics, 2017
This article presents a new method of solving partial differential equations. The method is an improvement of the previously reported compact finite difference quasilinearization method (CFDQLM) which is a combination of compact finite difference schemes
