Subject: Invited Mini-Symposia for ICIAM meeting

Hamburg , Germany

SIAM has been allotted 30 mini-symposia at the ICIAM meeting at
Hamburg, July 3 thru July 7, 1995. We invite you and your colleagues
to submit a proposal by July 15, 1994. THE PROPOSALS SHOULD BE SENT TO
THE SIAM OFFICE. The final decision on the mini-symposia will be made
by the the ICIAM Program Committee to insure a balanced program.
Forms for making the proposal can be obtained from SIAM
( or from the SIAM gopher. (These forms are for the
genaral call for mini-symposia; ignore the dates and address of
return.) We welcome suggestions for other topics and organizers.

A final decision on mini-symposia will be made by Sept 15, 1994.

Here is some information and helpful comments. These suggestions are
guides but they are not inviolate.

1) In the interest of fairness, an individual should not participate
and/or organize more than one mini-symposium.

2) The organizer should be a member of SIAM but it is desirable that
the speakers be chosen to reflect the international character of the
ICIAM meeting.

3) If the organizer is a speaker then he/she should nominate another
person to chair the session.

4) No funding has been provided for the expenses of these mini-symposia.

5) The mini-symposium format allows for a variety of formats eg.
roundtable discussions, presentations of variable length, etc.

There will be a more general call for submission of mini-symposium at
a later date.

Subject: Jack Wisdom Wins a MacArthur Fellowship

Professor Jack Wisdom of MIT has been involved in a number of mammoth
computational studies of the long time dynamics of the solar system,
some of them on specially designed computing equipment. These have
involved innovative numerical techniques including the use of special
symplectic integration algorithms.

Associated Press story, June 14:
"For his research into the role of chaos in the stars, Wisdom
was recognized Monday with a "genious grant" from the John D.
and Catherine T. MacArthur Foundation.
The 41-year-old physicist at the Massachusetts Institute of
Technology will receive $260,000 over five years -- no strings
attached. Nineteen other people received similar awards.
Wisdom's reaction: "It's a complete gift from the sky."
Since 1981, the MacArthur Foundation, whose founder made his
fortune in insurance, has given out more than $120 million to
414 fellows. The recipients are nominated by anonymous talent
scouts and chosen on the basis of skill, creativity and

Official announcement:
"Jack Wisdom, 41, physicist, professor, Massachusetts Institute
of Technology. Significantly advanced understanding of solar
system dynamics. Grant: $260,000."

Subject: Mathematical Software Benchmarks for Workstations

We are in the process of setting up a Scientific Computing Laboratory
with 1-2 servers and 15 client workstations. In assessing the performance
of various models we would like to know how fast they execute numerical
and statistical software, such as MATLAB. Although the developers of
MATLAB and various workstation vendors have been quite helpful, we are
still unable to run the MATLAB benchmarks on certain workstations under
consideration (see ?? below). If anyone has done so, could they please
let me know? Thanks in advance.

We would also be interested to know of any benchmarks for these workstations
using other software such as Mathematica, IMSL, NAG, SAS, S+, etc. Would
the developers of these softwares consider maintaining a data base of
benchmarks that could be accessed by anonymous ftp, and that could be updated
by their own tests or those of their users?

Subject: Biomedical Databases

I am interested in any help from anyone out there on the
following subject.

We have become an information gathering
society. One of the areas of interest is the gathering of
large databases of information. I was wondering if
anyone out there might know of databases of biomedical
information and how to access them. For example,
GenBank, census data, databases of medical images,
databases of population statistics, environmental
toxicity data, dental data, etc. If you know of such data,
would you please send me the following information:

Name of Database:
Is the database public or private:
How to contact database or database owner.

I will summarize the responses for the list. This is a
rather urgent request so, rapid answers would be
appreciated. Do not worry about duplicating others.

Feel free to cross post this note to any other lists that
might be appropriate.

Subject: Two New Books

F.L.Chernousko. State Estimation for Dynamic Systems.
CRC Press, Boca Raton, Florida, 1994, 304p.

Researchers and engineers working in the field of applied
mathematics, systems modeling, control, and identification
will find this book very interesting. It is devoted to the
guaranteed, or minmax, state estimation of dynamic systems
which is a new and very promising branch of the mathemati-
cal theory of systems and control. The book presents the
state-of-the-art in this field and expounds the new effi-
cient method of state estimation proposed by the author.
The method makes it possible to obtain optimal two-sided
ellipsoidal bounds for reachable sets of linear and non-
linear control systems with discrete and continuous time,
to analyze practical stability of dynamic systems subjec-
ted to disturbances, to obtain two-sided estimates (fil-
tering) for dynamic systems in the presence of external
disturbances and observation errors. Numerical algorithms
for state estimation and optimal control, as well as
a number of applications and examples, are presented.
The book will be useful to researcers, professors, and
students in the field of applied mathematics and automatic

Felix L. Chernousko, Nikolai N. Bolotnik,
and Valeri G. Gradetsky. Manipulation Robots:
Dynamics, Control, and Optimization. CRC Press,
Boca Raton, Florida, 1994, 267 p.

Researchers and engineers interested in recent scientific
achievements in robotics will find this book very useful.
The book contains basic knowledge of robotics including
kinematics, dynamics, drives, control and sensor systems,
etc., as well as new results obtained by the authors.
The book covers challenging fields of research such as
dynamics of robots with elastic parts, optimal control
of manipulators, and new developments in robotics.
To evaluate the elastic compliance of robots and their
dynamic accuracy, the authors propose new efficient
computer techniques and give numerous experimental data.
Optimal control methods presented in the book allow
increasing the speed and productivity of robotic opera-
tions and reducing the energy consumption. New develop-
ments in robotics are covered including pneumatic sensors,
adaptive grippers, special robotic systems for measurement
and inspection, wall-climbing robots with technological
manipulators, etc.

Subject: Parallel Circus

1994 California Parallel Circus/ NA Day

Dear NA-Netters,

1994 California Parallel Circus/ NA Day was held June 6-7 at UCLA's
Lake Arrowhead conference center. This 2-day Day was organized by Tony
Chan and Gene Golub, aiming to to bring together NA groups at San Diego,
LA and the Bay Area and beyond for an informal workshop, with lots of
graduate student participation.

As some of you know, Lake Arrowhead is a fantastic location, with pine
forests, a clear blue lake, and crisp clean air. The UCLA facility
has nicely furnished lodgings, conference rooms, fireplaces, and an
overall rustic atmosphere. The food is not bad either.

Most of us arrived at the site Monday afternoon, registered and checked
in. We had two sessions that day, one before dinner, and one after,
leaving time to socialize in the Lakeview room after the late session.
Tuesday's events were divided into a morning and an afternoon session
with a group photo-op break. The talks continued till about 3 in the

For next year's NA Day some of the sites suggested were Asilomar and
Stanford. A bit earlier than June, and maybe on a weekend seemed to be
the preference of most participants.

Below is a list of the talks we heard.

This is the fourth international conference on CFD
organised by the ICFD (Institute for Computational Fluid
Dynamics), a joint research organisation at the
Universities of Oxford and Reading set up in 1983 with
the support of the SERC to collaborate with industry in
this area. Previous conferences were held at the
University of Reading in 1985 and 1992 and at the
University of Oxford in 1988 in a series of conferences
on the same theme held on the two sites over the last
thirteen years.

The aim of the conference, as in previous years, is to
bring together mathematicians and engineers and other
scientists in the field of computational aerodynamics and
computational fluid dynamics to review recent advances in
mathematical and computational techniques for modelling
fluid flows.

The subject area is very large with many active
researchers in industry, government laboratories and
universities working on a wide variety of methods and
applications. The conference will cover all areas of CFD
but it is hoped to emphasise three main areas:


In addition to invited lectures the programme will
include contributed talks of twenty minutes and
poster sessions. These will be selected mainly on
the basis of their likely contribution to the above

Two page abstracts for contributed papers should be
submitted by 9 December 1994 stating preference for oral
or poster presentation. Notification of acceptance will be
given by 31 January 1995. Papers accepted for oral
presentation will be required at the meeting for
publication in the Proceedings.

Subject: 2nd OpenMath Workshop

2nd O P E N M A T H W O R K S H O P

A workshop to formulate a character-based standard for the
exchange of mathematical formulas and other mathematical
objects between programs.

July 18 and 19, 1994
St. Catherine's College, Oxford

(scheduled to precede exactly the ISSAC 94 meeting)

During the recent past, enough interest was expressed in working
on a text-based standard for the inter-communication of mathematical
expressions. Several groups are presently working towards this goal:
OpenMath, Posso XDR, Multi, HCM proposal, etc. In December 1994, the
first OpenMath workshop took place in Zurich. The meeting was
considered very successful, and a second meeting was scheduled to
coincide with ISSAC. During the past months, several people have
made significant progress toward this goal.

Arrangements are now in place for this second workshop. We are
planning to arrive in Oxford on Monday (18th) morning. Although the
conference rooms are reserved for all day, there are no planned
activities for the morning. The meeting starts in the afternoon and
continues for all of Tuesday (19th).

This notice should serve a double purpose:

(1) Call for papers/contributions.

If you are interested in presenting a contribution at this
workshop (expected contributions should be 30 minutes long),
please send a title and abstract to This
should arrive in Zurich no later than June 30th in order to
have the final program ready for the meeting.

We are also expecting project updates from the groups mentioned
above. (But please, let us know about them too).

(2) Registration.

The Institute for Scientific Computation at ETH will cover the
expenses generated by the workshop (two lunches, coffee breaks,
conference rooms and one night of accomodation at the residences).

For this, we *must* have your registration on or before June 18th.
Please send your intention to register to:
