Computer visualization of the approximations of functions by several terms of their Fourier series
(Department of Educational Sciences, University of Cyprus, 2003)Fourier trigonometric series are a constant component of the basic course of calculus at Universities. If we teach the topic about the Fourier series in the classical way it is often necessary to give a lot of time to a ...

Spectral element discretization of the stokes equations in deformed axisymmetric geometries
(2011)In this paper, we study the numerical solution of the Stokes system in deformed axisymmetric geometries. In the azimuthal direction the discretization is carried out by using truncated Fourier series, thus reducing the ...
