    Notizen: The Successive Overrelaxation (SOR) and the Cyclic Chebyshev Semi-Iterative (CCSI) methods are considered for solving the non-symmetric linear systems Ax = b when A has the form \documentclass{article}\pagestyle{empty}\begin{document}$$ {\bf A} = \left({\begin{array}{*{20}c} {{\bf D}_1} & {\bf F} \\ {-{\bf F}^{\rm T}} & {{\bf D}_{\rm 2}}\\ \end{array}} \right) $$\end{document} with D1 and D2 symmetric positive definite (SPD).The D1/2-norms of both methods are determined and it is shown that, though the SOR method is better based on the spectral radius, the CCSI scheme is far better than SOR according to the D1/2-norm.

    Notizen: In this paper, the application of successive block overrelaxation methods to obtain the deflection of a skew plate are compared, although the techniques herein are applicable to a wider range of problems. An algorithm for the direct solution of the submatrices comprising the two-line blocks of the skew grid is presented and the results are compared with the block (line and peripheral) overrelaxation methods.

    Boundary value techniques for finite element solutions of the diffusion-convection equation (1986)
    Chichester [u.a.] : Wiley-Blackwell

    Notizen: In this paper, the formulation of six-point and nine-point finite element equations for the solution of the diffusion-convection equation is presented. The six-point equation requires the solution of a tridiagonal system of equations and the nine-point centred equation is treated as a solution of a boundary value problem which leads to a large linear system of equations.Some numerical experiments are presented and the comparison with existing methods is included.

    Implementation of an improved bisection algorithm in buckling problems (1983)
    Chichester [u.a.] : Wiley-Blackwell
    International Journal for Numerical Methods in Engineering 19 (1983), S. 1047-1052

    Thema: Mathematik , Technik allgemein
    Notizen: An improved bisection strategy is presented to determine the eigenvalues of a real symmetric tridiagonal matrix which occurs in a simple column buckling problem. The new strategy, which involves only a minor modification, utilizes incomplete Sturm sequences only as long as relevant information on the next and following eigenvalues is obtained resulting in a minimization of the computational work. The strategy is particularly effective if only a few eigenvalues are required. The technique can be used for a wider class of eigenvalue problems than the illustrative one presented here.

    Stress relaxation of natural rubber during irradiation (1969)
    New York : Wiley-Blackwell
    Journal of Polymer Science Part A-2: Polymer Physics 7 (1969), S. 725-733 
    Details
    ISSN: 0449-2978
    Schlagwort(e): Physics ; Polymer and Materials Science

    Thema: Chemie und Pharmazie , Physik
    Notizen: The site of chain scission and crosslinking in vulcanized natural rubber irradiated with 4 MeV electrons has been determined by analysis of stress relaxation data. Sulfur and peroxide vulcanizates of different crosslink densities were prepared and the crosslink densities determined from stress-strain measurements. Stress relaxation was measured during irradiation using modified commercial relaxometers. The specimens were maintained in an atmosphere of nitrogen to minimize oxidative side effects. Scission is deduced to take place in the vicinity of crosslinks, since the rate of continuous stress relaxation is independent of crosslink density. Scission may be associated both with crosslinks initially present and with those subsequently introduced by irradiation. Crosslinking by radiation is largely a random process. However, there is a crosslinking reaction dependent to a slight extent on crosslink density as well as a small contribution from random scission reactions. G values for the random reactions are given.

    Structure and radiation properties of large-scale natural gas/air diffusion flames (1986)
    New York, NY [u.a.] : Wiley-Blackwell
    Fire and Materials 10 (1986), S. 161-169

    Notizen: Recent data from large-scale turbulent natural gas/air diffusion flames (135-210 MW) were used to evaluate analysis of flame structure and radiation properties. The conserved-scalar formalism, in conjunction with the laminar flamelet concept, was used to predict radiative heat fluxes. The narrow-band model considered the nonluminous gas bands of water vapor, carbon dioxide, methane and carbon monoxide in the 1000-6000mm wavelength range. Structure predictions were encouraging, with discrepancies for mean temperatures (ca200 K in the hottest portions of the flames) comparable to experimental uncertainties, due to thermocouple errors, flame disturbances from ambient winds and lifting and external expansion effects near the injector. Radiative heat flux predictions were also reasonably good, e.g. predictions based on mean scalar properties were generally 15% lower than the measurements. The findings also suggest that continuum radiation from soot is negligible for these flames.

    High order difference group explicit (HODGE) methods (1986)

    Notizen: Point iterative methods at which, at any one time, only a single equation of the linear system is treated are well known. However, in recent times block (or line) iterative methods, in which a group of equations (or points on the grid mesh) are treated implicity and solved directly by a specialized algorithm, have become the standard techniques for solving the sparse linear systems derived from the finite difference/element discretization of a self-adjoint elliptic partial differential equation on a two-dimensional grid. The main concern of this paper is to construct new groupings of the mesh points of the network into four and nine points using the high order accurate nine-point finite difference equations and to investigate their advantages when used explicity in the standard iterative methods4,5,6.

    Notizen: In this paper, the implementation of the incomplete Sturm sequence evaluation of Evans et al. 2 is considered for the determination of the eigenvalues of a symmetric quindiagonal matrix A which occurs in vibrating beam problems. The method based on triangularization by elementary stabilized matrices involving the application of the bisection method for quindiagonal matrices is fully described in Sentance and Cliff, 3 and therefore only the changes to the proposed method in order to obtain high efficiency when dealing with several of the lowest or highest eigenvalues of quindiagonal matrices are discussed. The paper concludes with the FORTRAN program and the supporting numerical evidence.
