Subject: New Book, Wavelets and Filter Banks

WAVELETS AND FILTER BANKS Gilbert Strang and Truong Nguyen

Publication 1/96 by Wellesley-Cambridge Press

This new textbook by Gilbert Strang and Truong Nguyen offers a clear and
easy-to-understand introduction to two central ideas -- filter banks for
discrete signals, and wavelets. The connections are fully explained -- the
wavelet is determined by a choice of filter coefficients. All important
wavelet properties (orthogonality or biorthogonality, symmetry, accuracy
of approximation, and smoothness) come from specific properties of the
filters. The text shows how to construct those filters and wavelets.
We emphasize the usefulness of linear algebra.

The applications are very widespread -- and they continue to develop rapidly.
The book gives a direct approach to signal processing and image processing
through filter banks that iterate on the lowpass filter (this is the wavelet
idea). Blocking and ringing artifacts are analyzed, along with many MATLAB
applications. Wavelets and Filter Banks is written for the very broad
audience that uses these ideas:

Digital Signal Processing and Speech Processing
Image Processing including Medical Imaging
Scientific and Engineering Applications
Students and Professionals (wanting to understand wavelets!)

Please write to for the Table of Contents and for
information about ordering by email.

The Table of Contents and Guide to the Book are also in our homepage:

This book is the course text for the Tampa wavelet workshop, January 13-15.
For more information abourt the workshop, please send the message Workshop

The book is also closely linked with the Wavelet Toolbox for MATLAB that
MathWorks will announce in early 1996.

Thank you.

Subject: New SQP Optimization Software Available

To anyone concerned with continuous optimization:

I just have completed work on a new implementation of a SQP-method,
which forms the successor of my code "donlp" in netlib/opt. The new
version, being capable of solving problems with a much higher number
of constraints is immediately available for everyone from netlib in
the directory netlib/opt/donlp2.

Have fun in using it (hopefully) .

Subject: European Conference on Numerical Mathematics

Preliminary Announcement
2nd European Conference on Numerical Mathematics and Advanced Applications
September 29 - October 3, 1997

Heidelberg, Germany

After ENUMATH-95 has been held at Paris, September 18-22, 1995, there seems
to be a growing interest in having a periodical forum for discussion on
topics in Numerical Mathematics and Advanced Applications. Hence, a sequel
conference, ENUMATH-97, will be organized during the week Sept. 29 - Oct.
3, 1997, at the University of Heidelberg, Germany. The local organizers are
H.G. Bock and R. Rannacher.

The conference aims to provide a forum for the presentation and discussion
of recent results and new trends in Numerical Mathematics and its
applications with special emphasis on contributions from Europe. Leading
experts and other actively working scientists are invited to present their
results and views in lectures, mini-symposia and panel discussions. The key
point of the conference is the theoretical analysis of numerical methods
and algorithms as well as their applications to challenging scientific and
industrial problems. Numerical Mathematics progresses through close
interaction between numerical analysts, applied mathematicians and other
researchers engaged in mathematical modelling and scientific computing.
Special attention will be given to multi-disciplinary applications of
numerical mathematics and to new algorithmical approaches.

The Program Committee of ENUMATH 97 consists of:
6. Brezzi (Italy), R. Glowinski (France/USA), Yu. Kuznetsov (Russia), J.
Periaux (France), and R. Rannacher (Germany).

The following scientists have agreed to serve on the Scientific Committee:
O. Axelsson (The Netherlands), N. Bakhvalov (Russia), H.G. Bock (Germany),
C. Canuto (Italy), P. Deuflhard (Germany), M. Dryja (Poland), I.S. Duff

Subject: ATLAST Linear Algebra Workshops

ATLAST 1996 Linear Algebra Workshops

ATLAST is an NSF Project to Augment the Teaching of Linear Algebra
through the use of Software Tools. The project will offer two
faculty workshops on the use of software in teaching linear algebra
during the summer of 1996.

Workshop participants will learn about existing software for linear
algebra and will be trained in the use of the MATLAB software package.
Attendees will design classroom lessons that incorporate computer
software making use of ATLAST materials that were developed in previous
workshops. These materials will be included in the forthcoming "ATLAST
Book of Computer Exercises" (Prentice-Hall, Fall, 1996). Participants will
also learn to design computer exercises and lab projects for inclusion
in the ATLAST database and possible inclusion in future editions of the
ATLAST book.

The ATLAST Project provides room and board for participants attending
the workshops.

The project was conceived by the Education Committee of the International
Linear Algebra Society (ILAS). Steven J. Leon of the ILAS Education
Committee is serving as the ATLAST Project Director and the Assistant
Director is Richard Faulkenberry. Both are in the Mathematics Department
of the University of Massachusetts Dartmouth. The ATLAST project is
funded by a National Science Foundation Faculty Enhancement grant.

This is the fifth year of ATLAST workshops. Over 350 faculty members
have participated in the twelve workshops given during the summers of
1992, '93, and '95. A number of these participants were invited to attend
an advanced workshop in 1994. A second advanced workshop is now being
planned. Workshop evaluations and follow-up surveys clearly show that the
ATLAST program has been a rousing success. We are confident that the
'96 workshops will be equally well received.

Summer 1996 ATLAST Workshops

Workshop site: Salve Regina University, Newport, Rhode Island
Workshop dates: June 12--15, 1996
Workshop Presenter: Dr. Steven Leon, University of Massachusetts Dartmouth

Workshop site: University of California San Diego, La Jolla, CA
Workshop dates: July 24--27, 1996
Workshop Presenter: Dr. Lila Roberts, Georgia Southern University

All teachers of undergraduate linear algebra courses at colleges or
universities in the USA are invited to apply for the ATLAST workshops.
The deadline for applications is March 21, 1996. Late applications
will be accepted on a space available basis. Each workshop will be
limited to thirty participants. A screening committee will review

Scalable Pseudorandom Number Generator Library

We would like to invite outstanding candidates to apply for a
post-doctoral position available at the University of Illinois at
Urbana-Champaign. We are looking for a Computer Science or
Computational Physics PhD to participate in an ARPA funded project
related to parallel pseudorandom number generation. Pseudorandom
number generators are the foundation of stochastic methods used for a
wide variety of problems in natural and social sciences, industry,
financial services, the military, etc. The aim is the development,
parallelization and testing of a pseudorandom number generator
library, with particular attention to both portability and scalability
across parallel architectures. In addition, a set of utilities for
efficient polynomial computations is to be developed. A knowledge of
C is necessary, experience with parallel computing (e.g. MPI or PVM)
is desirable and familiarity with stochastic simulations would be a
plus. The project involves an interdisciplinary team of researchers
from the Dept. of Physics UIUC, the Institute for Defense Analyses,
the Dept. of Computer Science UIUC, and NCSA. The Urbana-Champaign
campus is a vibrant research environment and for a self-motivated
individual this project will be an excellent opportunity for
intellectual growth. The project will last for 2 years.

Applicants should send a CV, a list of publications and the names of
at least three references to Prof Faisal Saied,,
Department of Computer Science, University of Illinois at
Urbana-Champaign, 1304 W Springfield Ave, Urbana, IL 61801.
