Stiffness matrix of the Dirichlet problem (auI)I = f with a homogeneous boundary value condition in a spline wavelet basis has O(n log n) non-zero elements . We show that for a constant function a it is just O(n) and ...

A viscoelastic simply supported rotationally symmetric body, fixed on a base, is considered. The body is loaded by a flat plunger, which moves in the direction of the z axis by a constant velocity v. In this work the ...

The subject of the presented paper is a mathematical analysis and numerical solution of the sys- tem of nonlinear nonstationary reaction-diffusion equations. Firstly, using the invariant region technique, the proof of both ...

In this paper we deal with the development of a numerical method for the solution of the mo- dified equal width wave (MEW) equation – a very important equation with a cubic nonlinearity describing a large number of physical ...

The paper is concerned with theoretical and computational issues of a numerical resolution of

a vector which we have recently proposed in [1, 2]. The theoretical advantages of our scheme
• (Technická univerzita v Liberci, Česká republika, 2012)
The paper deals with the problem of non-parametric statistical modeling of 2-dimensional sur- faces from observed data, i.e. the regression analysis. In general, the model is constructed from a set of basal functions, as ...

We consider an unsteady 1D singularly perturbed convection–diffusion problem. We discretize such a problem by the linear finite element method (FEM) on a Shishkin mesh and by a discon- tinuous Galerkin method in time. We ...
