Subject: Bibtex Reference Base Available

I am making my bibtex reference base available by anonymous ftp at

The directory


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

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.

Subject: Public Domain ODE Boundary Value Programs

It looks like there are not many public domain ODE boundary value
programs in the netlib. The package provided by the ode in netlib
is about ten years old. I wonder if anybody knows a more recent
public domain package that handles the ODE boundary value problem?

Thanks in advance.

Subject: SVD in C or C++

Where is there a public domain singular value decomposition routine in C
or C++ in float or double, not complex?

A complex routine that uses a complex structure or class and does its math
through function calls or overloaded operators would be ok, anything that's
easy to convert to double.

Subject: Solid Dynamics Code Available

Our group at Amparo Corporation develops computer codes to model
the continuum physics of solids at extreme pressure and high strain
rates. 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.

There will be, on Friday June 28, 1991, a special one-day program of
invited technical presentations at Harvard University to honor Prof.
Garrett Birkhoff on the occasion of his 80th Birthday. This program
is part of, and is scheduled to take place at the end of the IMACS
begins on Wednesday, June 26 and ends on Friday the 28th (Garrett
Birkhoff's birthday was actually on January 11, but it was felt that
honoring him in June, and at the end of a Symposium on a subject that
is closely related to his many accomplishment would give an
opportunity to more of his past students, friends and colleagues to
participate). This day of presentations, organized and chaired by
Richard Varga, will be followed by a Banquet (at the JFK Center) on
Friday night.
