A Finite Element Approximation of the
"... We consider the NavierStokesAlpha model as an approximation of turbulent flows under realistic, nonperiodic, boundary conditions. We derive that the variational formulation of NavierStokesAlpha model under nonperiodic boundary conditions, and prove that it has a unique weak solution. Next we c ..."

FINITE ELEMENT APPROXIMATION FOR TV REGULARIZATION
"... Abstract. In this paper, we will develop the convergence of the solution of TVregularization equations with regularized parameter ε − → 0 in BV (Ω) for practical purposes. Originated from the effects of regularized parameter ε, the error rate of finite element approximation for TVregularization eq ..."

Finite element approximation of the p(·)laplacian
, 2008
"... Abstract. We study a priori estimates for the p(·)Laplace Dirichlet problem, −div(∇vp(·)−2∇v) = f. We show that the gradients of the finite element approximation with zero boundary data converges with rate O(hα) if the exponent p is αHölder continuous. The error of the gradients is measured in ..."

Mixed Finite Element Approximation of Eddy Current Problems
, 2003
"... Finite element approximations of eddy current problems that are entirely based on the magnetic field H are haunted by the need to enforce the algebraic constraint curl H = 0 in nonconducting regions. As an alternative to techniques employing combinatorial Seifert (cutting) surfaces in order to intr ..."

Finite element approximation on quadrilateral meshes
 COMM. NUMER. METHODS ENGRG
, 2001
"... Quadrilateral nite elements are generally constructed by starting from a given nite dimensional space of polynomials V ˆ on the unit reference square ˆK. The elements of V ˆ are then transformed by using the bilinear isomorphisms FK which map ˆK to each convex quadrilateral element K. It has been re ..."
