Subject: Trivariate Interpolation

Trivariate interpolation

Suppose we know f(x,y,z) for the points
i.e at the corners of a cube. We then seek a simple expression for the
values of f(x,y,z) inside the cube.
The expression is going to be used in a computer program, where this
expression is required several hundred million times.

Subject: Physical Review E, Computational Physics

On 1 January 1993 Physical Review A15 will become Physical Review E.
Beginning in January the journal will include a new subsection,
Computational Physics. The most appropriate papers for this section
will be those which seek to reach a wider audience of physicists than
that reached by specialized journals. We welcome papers describing
general computational methods that address significant physics
problems. Specific listings of programs, algorithms, etc., should be
reserved for supplementary material that would not appear in the
published article. Submissions to this new section are invited at
this time.

I might add that Irwin Oppenheim, the current editor of Physical Review
A15, will continue as editor of Physical Review E and that I will be
associate editor for the Computational Physics subsection.

Subject: SCADE93 Conference in Auckland

Travel to Auckland for SCADE93 Conference

Because January is within the New Zealand tourist season,
travel to Auckland for participation in the International
Conference on Scientific Computation and Differential
Equations, January 4-8, 1993, is becoming increasingly difficult
to arrange. This reminder is to urge the many people who
have indicated an intention to take part in the conference
to arrange their travel to Auckland as soon as they possibly can.
We would, of course, also appreciate registration for the
conference at the earliest date possible, to assist the
organisers with detailed planning. For some airlines
there are already waiting lists for travel to Auckland during the
Southern Hemisphere summer and it may already be too late to
come on a date you might prefer and at a favourable price.

Subject: Householder Symposium on Numerical Algebra



The Householder Symposium XII on numerical algebra will be held
during the week of June 13-18, 1993 at the UCLA Conference Center, Lake
Arrowhead, California, about a 2 hour drive from Los Angeles. This
meeting is the twelveth in a series, previously called the Gatlinburg
Symposia. It has been agreed to rename all subsequent Gatlinburg Symposia
to honor Alston S. Householder, one of the pioneers in Numerical Linear
Algebra and organizer of the first four Gatlinburg meetings. The meeting
is an international conference of experts in the field of Numerical
Algebra. The meeting has traditionally been held in an isolated location
and is very informal in style. Extended talks are given during
the day and special workshops organized by the participants in the
evening. There is no formal program, but traditionally a few topics are
emphasized; for this meeting this includes parallel computation issues,
signal and image processing, control, wavelets, nonsymmetric conjugate
gradient methods, domain decompositon and multilevel methods and
industrial problems.

The meeting is being organized by the Householder committee, in
cooperation with the SIAM Activity Group on Linear Algebra.
The local organizers are Tony F. Chan of UCLA and Gene Golub
of Stanford University. The venue is a first class rustic alpine
resort with modern conference and recreational facilities. The room
charge is $92 per person for a double room and $120 for a
single/private room and INCLUDES ROOM AND 3 MEALS A DAY
(spouses are allowed but not very young children).
It is hoped that we will have the whole conference center to ourselves.
There will be a modest registration fee (less than $100) to help
defray organizational costs.

The traditional format of the Householder Symposia requires that the
attendence be limited. The organizing committee invites all qualified
persons to apply to attend. For planning purposes, please let us know
of your intention to attend as soon as possible, preferably before December 1,
1992. We'll maintain a mailing list and keep you informed.
The actual application should consist of a vita and
an extended abstract (about two pages) of a paper you would present if
you desire to speak and are invited to speak.
The latter will be used by the committee in planning
the program. Material (preferably in machine readable form) should be
sent to us before February 1, 1993 (but the earlier the better) to:

Subject: Workshop on Real-Time Vehicle Simulation

Army Research Office Workshop in
Modelling and Analysis for Mechanical Systems and
Algorithms for Real-Time Vehicle Simulation

November 5-7, 1992
Brownestone Hotel
Raleigh, North Carolina


Computer simulation is playing a greater role in the design and analysis of
complex mechanical systems, the goals being improved designs and faster, more
reliable design processes. Often, the computer simulation must be performed in
conjunction with other devices or humans, such as in vehicle or flight simulat-
ors. In the case of human interaction it is essential that the computations be
carried out in real time. These issues are critical for military systems, as
the decline in defense spending shifts the emphasis from the procurement and
maintenance of vast military hardware to the capability for rapid high-techno-
logy responses to a wide variety of situations. They also have many obvious
implications for the improved competitiveness of American industry. Particular
applications to the Army include the design and stability analysis of vehicle
systems and weapons platforms. Thus, a workshop on Modelling and Analysis for
Mechanical Systems and Algorithms for Real-Time Vehicle Simulation is timely
and is both highly relevant and complementary to existing Army research activ-
ities. The need to bring together the diverse groups of engineers, control
theorists, numerical analysts, and computer scientists working in this field
led to the 1989 NATO Workshop on the Real Time Simulation of Mechanical Sys-
tems which was held in Snowbird, Utah. The meeting was uniformly praised by the
participants for the interaction that it spawned. Considerable progress has
been made since the NATO meeting. This ARO workshop may be considered to be the
first follow up meeting to the NATO workshop.

Themes of the Workshop:

The focus of this meeting is to bring together researchers from academia,
national laboratories, and Army scientists to stimulate collaboration on
problems of common interest arising the numerical simulation of the dynamics
of mechanical systems, especially vehicles. Topics to be discussed include

- Recent developments in sequential and parallel algorithms for
real-time simulation of ODEs and constrained systems, with
parallel and/or distributed computing architectures (e.g., trans-
puters) as an underlying issue;

- Delay-differential algebraic systems;

- Recent results of fundamental mathematical importance in differential-
algebraic equations (DAEs) related to constrained mechanical systems;

- New numerical methods/analysis;

- Investigations of stiffness in actual systems with DAE models;

- Modelling of vehicle systems;

- Software environments for real-time simulation

and related issues of adaptive nonlinear control. One important aspect of this
workshop is the intent to invite both Army and non-Army participants to pose
real problems encountered in complex vehicle simulation with the hopes of
stimulating discussion, posing solutions, and initiating future
