I've cobbled together a list of all of the freely available (and otherwise) graphics software I've found on the Web. There is a link to each package and each is briefly described. This list can be accessed at: http://www-ocean.tamu.edu/~baum/ocean_graphics.html Steven K. Baum (baum@astra.tamu.edu) Physical Oceanography Dept. Texas A&M ------------------------------ From: Gaetano Continillo Date: Tue, 26 Sep 95 17:16:33 MET Subject: New Book on Dynamics of Chemical Reactors I have co-edited a book introducing to some fundamental techniques in the analysis of the nonlinear dynamics of chemical reactors. Title: Analysis, Simulation, Dynamics of Chemical Reactors: Introduction to Some Fundamental Techniques 472pp., 1995, ISBN 88-7146-04-9 Editors: G. Continillo, S. Crescitelli, and P. G. Lignola Publisher: CUEN srl via Coroglio 156 80124 Naples, Italy Price: US $ 35.- About the book: A course was recently organised and held in Naples, Italy, presenting an introduction to the usage of those mathematical techniques - some being still in evolution, as the catastrophe, bifurcation and singularity theories - which are being acknowledged as very powerful in tackling a rather wide range of problems of chemical reactor dynamics, from the analysis of multiplicity of states to the kinetic lumping techniques. The course material was edited to constitute the body of this volume, with the aim of enlarging the possibly interested audience. A desired effect would hopefully be to draw the attention of the mathematical community towards a highly receptive application area, and of possibly stimulating the development of new textbooks on the "usage" of modern advanced mathematics. The organisation of the course and the publication of the book were made possible thanks to several different institutions, whose support is gratefully acknowledged. The royalties coming from the sale of any copy of the book go to the Department of Chemical Engineering, University of Naples "Federico II". More details on the book (list of contributors, contents, and a sample chapter) can be found on the Web at http://www.irc.na.cnr.it/gc/books/index.html Please feel free to contact me for further information: Gaetano Continillo Istituto di Ricerche sulla Combustione CNR Naples, Italy Tel. +39-81-570 5864 Facs. 762 2915 E-mail gaetano@irc.na.cnr.it ------------------------------ From: Maurice Clint Date: Wed, 27 Sep 95 13:52:08 +0100 Subject: Solving Sparse Linear Equations on the T3D A colleague in Applied Mathematics requires to solve a system of linear equations having the following characteristics. The coefficient matrix is of order 50000; it is symmetric, possibly singular, with complex elements on its diagonal. There are multiple right hand sides. Currently he is using, not very successfully, a bi-conjugate gradient method - so it may be the case that the square of the coefficient matrix is ill-conditioned. He would like to have a stable method which can make efficient use of the Cray T3D. Has anyone encountered problems of this sort? If so, can you suggest a good method to use?

And perhaps let us know the reference. Many thanks in advance Hermann Haaf Suedwest LB Stuttgart ------------------------------ From: Daniel Hershkowitz Date: Thu, 28 Sep 1995 08:59:22 +0200 (EET) Subject: The Electronic Journal of Linear Algebra ILAS, the International Linear Algebra Society, announces a new electronic scholarly journal, as an outlet for high quality articles on Linear Algebra and its applications.

The Server provides remote solution of optimization problems over the Internet. Users can submit problems via email, ftp, or the World Wide Web. Results are returned via email and/or their Web browser. The NEOS server uses state-of-the-art algorithms to solve optimization problems automatically with minimal input from the user. For example, users with nonlinear problems can opt to have derivatives calculated automatically. The NEOS Server currently solves problems in the following areas: Linear Programming Unconstrained Minimization Stochastic Linear Programming Bound Constrained Minimization Linear Network Optimization Solvers in other optimization areas are under development. You are encouraged to use this service and send comments to neos-comments@mcs.anl.gov The NEOS Server is operated by the Optimization Technology Center, a joint venture of Argonne National Laboratory and Northwestern University.
