We consider the permeability estimation problem in two-phase porous media flow. We try to identify the permeability field by utilizing both the production data
In this paper, the linear finite element approximation to the positive and symmetric,linear hyperbolic systems is analyzed and an O(h2) order error estimate is
In order to construct closed surfaces with continuous unit normal, we introduce a new spline space on an arbitrary closed mesh of three-sided faces. Our approac
This paper is conceed with the stability of theoretical solution and numerical solution of a class of nonlinear differential equations with piecewise delays. At
A shift splitting concept is introduced and, correspondingly, a shift-splitting iteration scheme and a shift-splitting preconditioner are presented, for solving
Based on the finite difference discretization of partial differential equations,we propose a kind of semi-implicit θ-schemes of incremental unkriowns type for
