Subject: Eigenvalues of Block Toeplitz Matrices

I am interested in finding the eigenvalues and eigenvectors
of hermitian 5 diagonal block Toeplitz matrix in the following form:

H 0 H+1 H+2 0 .....
H-1 H 0 H+1 H+2
H-2 H-1 H 0 H+1
0 H-2 H-1 H 0

Here Hxx is a block of typical size of 252x252, and the whole matrix
is 21x21 blocks.

I would be very grateful for any help.

Subject: Pseudo-spectral Code for Navier-Stokes

Dear All,
I'am a graduate student working on wavelet-Galerkin scheme for
incompressible 2D Navier-Stokes equations in streamfunction-vorticity
formulation. I am looking for a pseudo-spectral code for this problem to
compare the results of my model. Any suggestion/source code would be
kindly appreciated. Thanks very much.

Best regards,

Subject: New Area Code for LLNL, SNLL

In case you aren't aware of it, the Tri-Valley part of the San Francisco
East Bay changed from the 510 area code to 925 effective March 14, 1998.
This change affects such communities as Concord, Livermore, Martinez,
Pleasanton, and Walnut Creek.

In particular, you must now use 925 to reach the Lawrence Livermore and
Sandia National Laboratories in Livermore. The new area code becomes
MANDATORY on September 12, 1998, so change your address books NOW.

Subject: New Book on Optimization and Decision Support


"The D_LP Optimization Model and Decision Support System"
by J.L. Nazareth; softcover; 194pgs; ISBN: 0-9657375-0-0;
published by Computational Decision Support Systems (CDSS);
US$ 19.00 plus postage and handling.

This book develops a new approach to computational optimization and
decision support for resource planning problems that arise, typically,
within the natural resource sciences and the disciplines of operations
research and operational engineering. It is based on a synthesis of
techniques of dynamic programming and linear programming---hence the
acronym D_LP---at both the modeling and the algorithmic levels. A basic
decision support system called the D_LP nucleus, which embodies this
new approach in a practical way, is described in detail. This nucleus
provides a foundation and staging ground for the hierarchical development
of D_LP models and solution techniques in a wide variety of application
areas. The D_LP approach has far-ranging implications and can be extended
in a variety of ways, as discussed, in particular, in Chapters 5, 6 and 10.

Main chapter headings and page numbers:

Part I: The D_LP Nucleus
Chapter 1: Two Simple Motivating Examples...3
Chapter 2: The D_LP Model...23
Chapter 3: D_LP Input Format Language...39

Extensions'', which will be published towards the end of this year under
an established banner.

Subject: PLAPACK Correction

In recent NA Digest submissions, we reported performance numbers for
PLAPACK vs. ScaLAPACK on our Cray T3E-600. In compiling numbers for
ScaLAPACK, we measured performance of the ScaLAPACK library that is
part of the Cray scientific library. We were not aware that the Cray
scientific library is compiled with "streams" turned off. The default
for our system is to have streams turned on for both compilation and
execution, and thus PLAPACK was compiled and executed with streams
turned on.

Corrected performance numbers (for the LU factorization based
solvers) are given below. Performance numbers for the Cholesky
factorization must be adjusted similarly.

Subject: UFE Workshop Announcement

UFE Workshop: Shodor Computational Science Institute

Applications are being accepted for the Shodor Computational Science
Institute (SCSI), a series of workshops designed to introduce the
use of modeling in the undergraduate mathematics, science, and
computer science curriculum. The SCSI Project is designed
enable teams of faculty at small-to-medium sized institutions to work
together to use technology, modeling and the tools of computational
science in their classrooms.

Two workshops will be held during June 1998 (and repeated during the
summer of 1999) in the Leroy Walker Complex on the campus of North
Carolina Central University, located in Durham, North Carolina.
Participants may choose to enroll in either workshop or both, in either
the same or successive summers.

The first workshop is designed to introduce faculty to modeling and
the basics of computational science. Participants will learn how to
locate resources, how to assess the value of those resources, and how
to adapt those resources to their classes. Faculty will have the
opportunity to learn about moving existing materials and simulations
to the web.

This more advanced workshop is designed to enable faculty to develop
and refine their own materials and interdisciplanary projects. Attendees
should be graduates of the introductory workshop, a previous modeling
workshop, or demonstrate sufficient experience with modeling
and simulation environments. Emphasis will be placed on development or significant adaptation of materials to be used in the classroom.

All local room and board expenses will be covered. Faculty participants
will receive a stipend of $500 per workshop. In addition, each team will
receive a software allowance of $750.

Subject: Postdoctoral Position at Unilever Research


The Process Principles Unit of Unilever Research, Vlaardingen, The
Netherlands, is looking for a postdoctoral fellow to conduct research
on the modeling of complex adaptive system applied to micro-structure
formation, such as crystal network formation, aggregation, etc. One
characteristic of these processes is that the relevant phenomena occur
on several scales. For example, to model crystallization, it is
necessary to account for molecular behavior at the microscopic level,
the formation and growth of crystal aggregates at the mesoscopic level,
and the overall flow rheology and heat transfer at the macroscopic

An emerging technique in Complexity Science, which is able to take
into account the coupling between the phenomena on different scales,
is the agent based modeling. With this technique, the behavior of many
individual agents (such as molecules) interacting with each other and
with a dynamically changing environment is modeled. The micro-
structure formation process emerges in a highly nonlinear manner from
the behavior of the individual agents, and this collective behavior is
integrated to a different scale of resolution.

The aim of the position is to combine the latest developments in agent
based modeling with state-of-the-art numerical simulation techniques
in order to perform pioneering work in micro-structure formation and,
in a broader context, to assess the potential of these promising
techniques. This is an excellent opportunity to perform world class
research on a subject of major importance for the future. As part of
the project, collaboration with the Santa Fe Institute, USA, one of
the leading institutions in Complexity Science, is envisioned.

Unilever Research, Vlaardingen, is one of the three research
laboratories of Unilever in Europe. Some thousand researchers work in
projects on the innovation of products and processes for the benefit
of Unilever companies. With 300.000 employees in 90 countries all over
the world, Unilever is one of the major Foods & Home and Personal Care
Products companies in the world.

Candidates are expected to hold a Ph.D. in engineering or physics.
Experience in some of the following areas is highly desirable:
mathematical modeling, computational techniques, fluid mechanics, heat
and mass transfer, thermodynamics, and object oriented programming
(C++, Objective C). The successful applicant will be able to work
independently, at the highest technical level, with a broader view on
science, and technology in general.

The term for the postdoctoral position is two years, starting as soon
as possible.
