Subject: Happy Birthday to Valery Pavlovich

Dear Editor of NA-digest:
We are the team from Computing Center, SD RAS, Novosibirsk, Russia.

He is a famous Russian scientist in numerical mathematics and computational
algebra known also in many other countries.
Would you be so kind to put the following congratulation into the
nearest NA-digest. We hope that this information will remind many scientsts
who know him to send him congratulation message.

Thank you in advance,
Staff of Computing Center.

Dear Valery Pavlovich:

All the staff of Computing Center congratulate you
from the very bottom of their hearts with your

60-th birthday!

Subject: Teletraffic Analysis of Telecommunications Systems

Introducing the Software Package TELPACK** (TELetraffic PACKage):

There has been substantial recent developments in teletraffic analysis of
modern telecommunications systems. Among these, numerical treatment of
structured Markov chains of M/G/1 and G/M/1 type, QBD processes, etc. are
important examples. These Markov chains arise very naturally in the analysis of
a wide variety of such systems.

Recently, Akar and Sohraby have used a new "invariant subspace" based approach
for the solution of such chains which in most cases of interest has shown a
marked improvement in CPU time and accuracy over the conventional methods. The
new algorithms have been implemented in C and put together in a software
PACKAGE by Anuj Agrawal (MS Thesis). Major modifications were made to the
original software by Dr. Nihat C. Oguz. TELPACK provides a simple user
interface which is currently in a TEXT format. In most of the cases (e.g.,
M/G/1 Type Chains), it also gives the option to the user to employ number of
other existing approaches. TELPACK is menu driven and contains help files and
many example files to assist the user for setting up the input data files, etc.
It also has the option of producing a PLOT associated with the stationary
distribution of the chain. As output, TELPACK provides moment information,
tail behavior, prob. of empty system, etc.

TELPACK uses the LAPACK routines (LAPACK Manual: E. Anderson and Z. Bai and
C. Bischof and J. Demmel and J. Dongarra and J. Du Croz and A. Greenbaum and
S. Hammarling and A. McKenney and S. Ostrouchov and D. Sorensen)

We hope that TELPACK will be a useful tool for research, education and
development. This is how to get TELPACK:

Subject: Godunov Symposium

Godunov's Method for Gas Dynamics:
Current Applications and Future Developments

May 1-2, 1997, University of Michigan, Ann Arbor, Michigan

Hosted by: W. M. Keck Foundation Laboratory for Computational Fluid Dynamics,
Department of Aerospace Engineering, College of Engineering, and others.



On May 3, 1997, the Russian numerical/applied mathematician S. K. Godunov
(Institute of Mathematics, Russian Academy of Sciences, Novosibirsk, Russia)
will receive an honorary degree from the University of Michigan, for
"tremendous contributions [...] made in the field of computational
fluid dynamics." To amplify this festive event, an international
symposium will be held on May 1-2, on the subject of Godunov-type
numerical methods, used world-wide to compute continuum processes
dominated by wave propagation. The title of the meeting is
"Godunov's method for gas-dynamics:
current applications and future developments;"
the venue is the Franc,ois-Xavier Bagnoud (FXB) Building, home of the
Department of Aerospace Engineering and located in the College of
Engineering on the University's North Campus.
Chairperson of the Symposium is Prof. Bram van Leer (Aerospace

You are cordially invited to participate in the symposium.
For those who also wish to attend Prof. Godunov's graduation
during the Commencement Excercises in the Michigan Stadium,
a limited number of good seats are available.

The purpose of the conference is to give an overview of the current
state of development and use of Godunov-type methods in science
and engineering, and to offer a perspective of their future
development and use. In the context of the symposium, Godunov-type methods
are loosely defined as non-oscillatory finite-volume schemes
that incorporate the solution (exact or approximate)
to Riemann's initial-value problem, or a generalization of it.
"Generalization" means that, for example, multidimensional fluctuation
splitting is included.

2 Research Positions at Vienna University of Technology

The Institute for Strength of Materials at
Vienna University of Technology (Head: Prof. H. Mang)
invites applications for two positions as research assistants in
the area of numerical simulations of tunnel excavations.

Recently, a joint research initiative (JRI) on


has been approved by the Austrian Fund for Scientific Research.
Seven scientists from 3 Austrian universities will
participate in the JRI.
The following two individual projects will be performed at the
Institute for Strength of Materials at the Vienna University of Technology:

Project I: Computationally efficient algorithms for
3D simulations of tunnel advance considering large deformations
and localized failure
(Head of the project: Univ.Doz. Dr. G. Meschke)

This project will provide efficient computational
algorithms for 3D finite element simulations
of tunnel excavations considering the effect of large
deformations and localized failure
in addition to the inelastic material behavior of soil
and of shotcrete.

Project II: Development and application of a constitutive model
for shotcrete
(Head of the project: Prof. Dr. H. Mang, Ph.D.)

Based on experimental evidence, improved constitutive models
for the consideration of the thermochemomechanical behavior
of shotcrete within the framework of finite element analyses
will be developed.

Both positions are open for Ph.D. Students and/or Post-Docs.

We are looking for individuals with a (Dipl.Ing.) or
a Ph.D. (Dr.Ing.) in Civil Engineering or Engineering Mechanics.
The positions are meant for work leading towards a Ph.D.
or a habilitation.
The successful candidates must possess a strong interest in
computational mechanics. Experience in material modelling
and finite element technology is highly desireable.

Both positions are purely research-oriented. no teaching activities
are required. The positions offer the unique possibility
to cooperate within a team of experts in different pertinent areas
connected with tunnelling and numerical analysis.
The candidates will have access to excellent computational facilities.

Applications will be accepted until the positions are filled. Applicants
should send a concise curriculum vitae to
