Subject: A Linear Algebra Problem?
Here is an example of a general classs of problems: this one is stated
in two dimensions:
Given a set of points P(i) in the plane which it is believed lie on a
collection of lines (number of lines unknown, but obviously
significantly less than half the number of points). Of course, there
are some errors in the given coordinate values of the points.
Problem: determine the lines. [The problem is not well specified,
and, at this stage, the specification could be partially dependent on
available algorithms. For example, one could ask for the minimum
number of lines subject to an error bound in a suitable norm. That

Subject: Experience with Mac-based Computer Labs
Our Departmental computer gurus are attacking the University decision to
create more Mac labs for students (software might include Mathematica,
Systat, MATLAB, etc.) on the grounds that "it is well known that Mac labs
all over the country fail" because students intentionally or
unintentionally mess them up---with viruses, by changing Configuration
files, modifying defaults, etc (all the stuff that you can do on
user-friendly systems). It has been my uninformed impression that Mac labs
were generally quite successful. Can anybody provide any information on
this based on their own institution's experience? Is it necessary to have
Unix labs in order to be successful, however unfriendly they might be?

Subject: Help With Bio-Medical Computing Sought
We are a small Bio-Medical Engineering Group here in the Department of
Electronics Engineering, Chinese University of Hong Kong.
We have one memeber of staff, soon to be two, one postdoc, four PhD
candidates and one Masters Candidate.
Since we are such a small group, and because people do not actually
know what we do (they still think we design wheelchairs or something),
we are lowest in the faculties priorities for computing resources,
software purchases and general support. One of our models of the
current and voltage distributions inside the thorax for an injected
current takes over a week to run on our DEC workstaiton!
We are engaged in somewhat unique work, well of the beaten track and
as such the normal available software code is not up to spec.
Recently the faculty got delivered a DEC MPP12000 super-computer and it
is now up an running, further to this, Sun may be donating a SPARC1000
to the lab,providing that we can show that we really need it, otherwise
we get a SPARC10 and the Dean's own department get to keep the sun
sparc1000, incidently its the Dean's decision who gets the SPARC1000.
At this present time we need to find suitable software for both the
MPP12000 and SPARC10/1000 to show that we can actually exploit their
capabilities. Therefore does anyone know or have suitable software
that could be ftp/ip and installed here?
I personally have to model the acoustical shock wave response of the
Human Thorax and model the resonance to detect disorder, this system is
non-linear, even chaotic at time, inhomogenous, and time VARIANT, as
well as different for different people, there are also no papers, no
books and no software, so I do not have time to sit and spend 2 years
writting everything I need.
We are especially interested in the following
1. General Bio-Medical Engineering Software.
2. Monte Carlo Modelling
3. CHAOS Dyanamics****************
4. Non-Linear system modelling*****
5. Acoustical propagation (inside human thorax!)
6. N-Degree of freedom resonance modelling software
7. Electrical Bio-Impedance.
8. EEG,ECG Anaysis software.
9. Mathematics Libraries/tools etc***
10. WAVELET ANALYSIS **********
11. Digital Signal Processing.
If someone has "inverse problem" software that could map EEG signals
onto a plane to show the electrical activity of the brain then we would
be very interested indeed.
Any help, advice or general comments would be most welcome.

Subject: Transformations of Linear Second Order ODEs.
I am writing this message to ask for help.
One of my research areas is about the 'direct' numerical methods for
initial value problems of second order ordinary differential equations in
which the first derivative is present. It is the first derivative that
presents difficulties to the construction of such method. One of the problems
for these 'direct' algorithms is if the coupled ODEs can be written into the
form of uncoupled ones which have the same solution as the original problem.
The IVPs of second order ODEs can be written as
known: x(0) and x'(0)
where [M], [C] and [K] are n by n symmetric matrices and x, x' and x" are
The technique assuming that the damping matrix [C] is proportional
to [M] and [K], i.e. [C]=a[M]+b[K], is commonly used in engineering
applications. Thus, a orthogonal transformation can be used to uncouple the
The simplified form of (1) is:
x"=-[C]x'-[K]x +f(t) (2)
known: x(0) and x'(0)
My question is: assuming that the [C] in (2) is an arbitrary symmetric
matrix, if we can find out the equivalent uncoupled equations with the

The eigenvalues of the matrix [B] are complex in general. The imaginary

solving the original problem (2) with a numerical method is equivalent to
solving the uncoupled problem (6)?

Subject: New Book on Convex Analysis and Minimization Algorithms
Authors: J-B.HIRIART-URRUTY,Universite Paul Sabatier Toulouse
and C.LEMARECHAL, I.N.R.I.A. Rocquencourt, France.
2 volumes: Vol.1 FUNDAMENTALS, 440p.
Vol.2 ADVANCED THEORY AND BUNDLE METHODS, 346p.
Editors: Springer-Verlag,Publication : October 1993.
Title : CONVEX ANALYSIS AND MINIMIZATION ALGORITHMS
Convex analysis can be considered as a refinement of standard calculus, with
equalities and approximations replaced by inequalities.As such, it can easily
be integrated into a graduate study curriculum.Minimization algorithms, more
specifically those adapted to non-differentiable functions, provide an
immediate application of convex analysis to various fields related to
optimization and operation research.These two topics, making up the title of
the book, reflect the two origins of authors, who belong respectively to the
academic world and that of applications. The approach of their book is very
comprehensive without being encyclopaedic : the emphasis is on introducing
readers in a gradual and digestible manner to the concepts of convex analysis,
their interlinking and their implications, with algorithms ideas worked in.
Theory is interspersed with applications and vice versa; illustrative numerical
results are given, and over 170 pictures illustrate and support geometric
intuition . Throughout the book, ample comments help the reader further to
master the concepts and methods, and to understand the motivations, the
difficulties, and the relative significance of results.

Subject: Templates for the Solution of Linear Systems
We have just completed a book on iterative methods.
The book is primarily aimed at computational scientists who are
not specialists in computational linear algebra and would like to
incorporate state-of-the-art computational methods for solving
large sparse non-symmetric systems of linear equations.
The title of the book is ``Templates for the Solution of Linear
Systems: Building Blocks for Iterative Methods'', is authored by
Richard Barrett, Mike Berry, Tony Chan, Jim Demmel, June Donato,
Jack Dongarra, Victor Eijkhout, Roldan Pozo, Chuck Romine and
Henk van der Vorst, is being published by SIAM, and will be available
in bound form in mid-November. SIAM has set the price for the
Templates book at List Price $18.00 / SIAM Member Price $14.40.
We are putting the royalties from the book into a SIAM fund
to help support students attend SIAM meetings.
The book contains:
o) Mathematical descriptions of the flow of the iterations.
o) Algorithms described in Fortran-77 and MATLAB.
o) Discussion of convergence and stopping criteria.
o) Suggestions for extending each method to more specific matrix types
(for example, banded systems).
o) Suggestions for tuning (for example, which preconditioners
are applicable and which are not).
o) Performance: when to use a method and why.
SIAM is trying an experiment with this book and has allowed the
postscript file containing the book to be distributed over the
internet. It is available from netlib.
To retrieve the postscript file you can use one of the following methods:
1) anonymous ftp to netlib2.cs.utk.edu

The 1994 International Conference on Qualitative Information, Fuzzy
Techniques, and Neural Networks in Simulation brings together research paper

applications, and software demonstrations that make use of qualitative
information of some sort or other in models of dynamic systems for the purpose
Research papers are welcome in the following categories of presentation
