W. Stewart Date: Fri, 1 Mar 91 10:40:27 -0500 Subject: Bibtex Reference Base Available I am making my bibtex reference base available by anonymous ftp at thales.cs.umd.edu. The directory /pub/references contains the files README, ref.bib, and bibsearch.tar. The reference base ref.bib contains approximately 1230 entries and is growing (it will be updated regularly). In particular it contains all the references for my book with J.-g. Sun, Matrix Perturbation Theory. Each entry in ref.bib contains a field, labeled kwds, with key words for the entry. The file bibsearch.tar contains a program to search a bib file on these key words. I have found it useful either for browsing or for creating impromptu bibliographies. Other directories on thales that are open to anonymous ftp are /pub/reports dvi files of my recent reports /pub/matrixpert errata for my book Pete Stewart stewart@cs.umd.edu ------------------------------ From: Mark S. Johnson Date: 1 Mar 91 21:06:44 GMT Subject: Numerical Methods in Smalltalk Is there any source code available to the public demonstrating numerical methods in Smalltalk? As a starting point, I'd like to see Matrix and Vector classes with methods for matrix operations and linear algebra. Scalar and Vector Function classes with methods for quadrature and nonlinear equation solving and optimization (for starters). Anything else that may be useful or interesting to an engineer.... I'm trying to improve my Smalltalk skills so "style" may be more important than "content" at this point. I'm building a scalar "Function" class now for practice and I find that I have more doubts about my class DESIGN than anything else. Thanks in advance. Mark Mark S.

The traditional users of our codes have been researchers in the DoD and DoE working on the design of conventional weapons and armor. We would like to push out a bit more however into areas like the shock synthesis of materials and high pressure research. We currently have a new code under development which employs domain decomposition techniques for modeling large deformation solid dynamics and which has coupled into it a library of constitutive models for solids. It is also fairly easy to add constitutive models. We expect to be beta testing late this spring or early summer. The code is three dimensional, but can be run as one or two dimensional Cartesian by restricting the size of the three dimensional mesh. We have written the code to run on the Sparc series of Sun computers and the Cray. Parallel versions are being experimented with, currently for the Cray and nCUBE. This code, TOLTEC, is a proprietary product of Amparo, but we do not intend to charge a fee for it. It is export controlled however, so anyone interested in using it has to satisfy and obey certain restrictions dictated to us by DoD. We would very much like to see this code used outside of the government however by universities and industry. If anyone out there would be interested in further information on TOLTEC or would be interested in beta testing it, please contact me. The kinds of things that it might be particularly useful for are high pressure research where you need to understand the hydrodynamics, anything to do with penetration of solids (for example, trying to design blast resistant or fragment resistant containers), high explosive simulation, shock synthesis of materials, etc... We have a very limited staff, so we don't know yet how much support we will be able to offer users of the code, but we will certainly try. Documentation will initially be somewhat sparse, but that will improve into the summer. -- John John K.
