A mixed Chebyshev spectral-finite element method is proposed for solving two-dimensionalunsteady Navier-Stokes equation. The generalized stability and convergen
Some two-scale finite element discretizations are introduced for a class of linear partial differential equations. Both boundary value and eigenvalue problems a
In this paper, nonrefiecting artificial boundary conditions are considered for an acousticproblem in three dimensions. With the technique of Fourier decompositi
In this paper, an algorithm for unconstrained optimization that employs both trust region techniques and curvilinear searches is proposed. At every iteration, w
In this paper we present a nonmonotone trust region algorithm for general nonlinear constrained optimization problems. The main idea of this paper is to combine
This paper is devoted to the development of a new stabilized finite element method forsolving the aivection-diffusion equations having the form -κ△ u + a @ V
