Keywords: nodal splines, singular integral equations Abstract: In this paper we introduce a nodal spline collocation method for the numerical solution of Cauchy singular integral equations. Uniform error bounds of the approximate solution are provided and some numerical examples are presented.   Download PDF

Ragni, Moody T. Chu, F. Diele, C. Marangi Pages: 139-156 The Leontief model, originally developed for describing an economic system in terms of mutually interrelated and structurally conditioned simultaneous

Date of Online Publication: 31/03/2006 Keywords: Ordinary differential equations, boundary value problems, collocation, residual, Authors: J. Kierzenka, L.F. Shampine Pages: 27-41 We describe the algorithms and implementation of the bvp5c program for solving boundary value problems (BVPs) for ordinary differential equations. A remarkable relationship between scaled residual and true error is established for the four-point

Received 16 December, 2009; accepted in revised form 24 September, 2011 Abstract: We investigate the use of piecewise linear systems, whose coefficient matrix is a piecewise constant

Keywords: circular cylinder, wall-mounted, LES, DES, imaging measurements Abstract: Numerical simulations of the turbulent separated flow around a wall-mounted finite cylinder were performed in order to assess the predictive accuracy of the methods for the unsteady flow field at high Reynolds number. While the results obtained from Large-Eddy Simulation show only minor diferences to experiments,
