Subject: W. E. Arnoldi
Today I received a sad news from Mrs. Flora Arnoldi that Walter Edwin
Arnoldi passed away on Oct. 5, 1995 at the age of 77.
Almost all numerical analysts know the name of Arnoldi associated with
the Arnoldi process, which is popular like as the Lanczos process in
the iterative solution of matrix eigenvalue problem. He first presented
the idea in his paper titled by "The principle of minimized iterations
in the solution of the eigenvalue problem" in Quart. of Appl. Math.,
Vol.9 in 1951. However, while I had tried to look for his personal data,
I did not come across anybody who mentioned this reference.
Last January I found out an article about W. E. Arnoldi in the
encyclopedia "American Men & Women of Science" (18th edition, Vol.1)
published in 1993 by R.R. Bowker, New Jersey. Immediately I wrote a
letter to the address of West Hartford of Connecticut given in the
encyclopedia. It is a great regret, however, my recognition was a
bit late. We missed him.
Here is a summary of the biographical information in the encyclopedia.
He was born Dec. 14, 1917 in New York. He graduated from the Faculty
of Mechanical Engineering of Stevens Inst. of Technology in 1937, and
studied in the course of Master of Science of Harvard Univ. in 1939.
Afterwards he worked as an analytic engineer in Hamilton Standard Div.
of United Aircraft Corp. starting in 1939. His positions included
project engr. 1939-44, system engr. 1944-51, senior tech. specialist
of advance planning 1951-59, chief advance analyst 1959-60, head product
researcher 1962-67, chief division researcher 1967-70, and division tech.
consultant 1970-1977. He retired in 1977.
His main research subjects covered vibration of propellers, engines and
aircraft, high speed digital computers, aerodynamics and acoustics of
aircraft propellers, lift support in space vehicles and structural materials.
Her letter to me makes me feel that Mrs. F. Arnoldi falls in deep
sadness. His name, however, will remain forever with the process
he devised.

Subject: The Thomas Algorithm
My query about the Thomas Algorithm in last week's Digest elicited
over two dozen responses, some from old friends who I hadn't heard
from in years. Thanks to all who replied.
Llewellyn H. Thomas is a distinquished physicist who in the 50's
held positions at Columbia University and at IBM's Watson Research
Laboratory when it was located adjacent to the Columbia campus.
He is probably best known in connection with the Thomas-Fermi
electron gas model.
The so-called Thomas Algorithm is indeed just a form of elimination
for solving tridiagonal systems of linear equations. But it usually
associated with the systems that arise from finite difference
approximations to partial differential equations. The attribution
to Thomas seems to be more common in some engineering disciplines
than it is in numerical analysis.
W.F. Ames writes in his book [1]:
"The method we describe was discovered independently by many and has
been called the Thomas algorithm (see [2]) by (David) Young. Its
general description first appeared in widely distributed published
form in an article by Bruce et al. [e]."

Subject: ICIAM Proceedings
[Editor's Note: Here is a response from ICIAM to the query in last week's
NA Digest about the status of Proceedings.]
The ICIAM organizers received altogether approximately 4500 pages
(Minisymposia, Contributed Papers and Poster Sessions). They had originally
available only 2400 pages for the planned 4 special issues in ZAMM, but ZAMM
has agreed to publish a fifth issue which allows us to print additional
600 pages(GAMM is paying apprroximately 90 000 Deutschmark for the 5 issues
to ZAMM).
Therefore we still have to reject 1500 pages submitted for the Proceedings.
We had to start a very careful and time consuming refereeing process. This
process is still not completed but most of the work has been done.
In addition to the large number of contributions a series of problems
appeared which the organizers did not expect:
1. Many contributors sent their paper to more than one or even to all
editors of the originally planned 4 issues. This caused confusion and is
still not completely solved.
2. In the guidelines evey submitter of a contribution was asked to send both
a hardcopy and a TEX-File. About 50% of the contributions have been received
only by hardcopies. Very often it was not possible to print the Tex-File.
Therefore we had to write a lot of letters and e-mails. Some people still
have not replied to this.
I have asked the the three other editors of the 5 special issues about the
current status of their issues. First of all, all of them confirmed that
enquiries concerning submitted papers have been promptly answered. The 5
issues are in the final stage and after sending them to the publisher all
contributors will be informed if their paper has been accepted or not. This
will be done via e-mail and/or regular mail. At the moment my impression is
that this will happen during the next three months. Until then we ask everyone
for patience. From the number of pages submitted one can see that we really
have to do a very big and difficult job.
Sincerely yours,
G. Alefeld (Treasurer of GAMM)

Subject: Good News About ICIAM Proceedings
Dear Colleagues,
In the last NA-Digest I have posted a message (representing my three
colleagues and myself) about the ICIAM Proceedings. It looks like we have
touched a very sore spot of some NA-readers. I have received about 16
messages (representing individuals and groups of researchers) describing
the same situation. After submitting papers no confirmation has been
received. Any attempt to contact the Conference Organizers over the e-mail
had the same effect: none whatsoever. For all of us I have GOOD NEWS!!!!
I have received about 5 responses that within the last 2 weeks they have
received confirmations that the papers will be published. This seems to
suggest that things are moving and we just need to have a little bit more
patience.
I would like to express my deep gratitude to everyone who has responded
to our query.
Respectfully,
Marcin Paprzycki

Subject: Nonlinear Data Fitting
I have some experimental data F(x) (an approximation to the actual
values f(x)) at locations x which I wish to fit to my model
expression:
infinity
f(x) = a*x**(-2)*abs( integral exp(-kz)*exp(ixz) dz )**2
0
+ b*x**(-5/3)
+ c
and from which I wish to obtain the unknowns a,b,c and k.
Can anyone suggest
1) a means by which this problem can be couched in Hermite or Chebyshev
polynomials (or some other means?)
2) a method which will accurately determine the values (speed is not
of importance but accuracy really is!), and
3) suggested reading to enable me to encode the method and test it's
accuracy?
Thanks in advance for all of your help.

Subject: Afternotes on Numerical Analysis
I have recently published a book entitled Afternotes on Numerical
Analysis which members of this group may find useful. It is a series
of 22 lectures on elementary numerical analysis. The notes themselves
were prepared after the lectures were given and are an accurate
snapshot of what went on in class. Although they are no substitute
for a full-blown numerical analysis textbook, many people have found
them a useful supplement to a first course.
The book is published by SIAM. For further information contact

We're pleased to announce the re-publication, in an inexpensive
softcover format, of "Numerical Methods for Nonlinear Optimization
and Nonlinear Equations" by J.E. Dennis Jr. and R.B. Schnabel in
the SIAM Classics in Applied Mathematics series, #16. The book is
unchanged from the original 1983 version except for the correction
of a large number of typos. It remains a current reference for
methods, theory, and pseudo-code for the solution of small to medium
sized unconstrained optimization, nonlinear equations, and nonlinear
least squares problems.

Subject: Application of Interval Computations to Gravity
A Major Application of Verified Computing
An Application of Interval Computations to Gravity
Featured as One of the Major Scientific Results
The latest issue of "Discover", the popular science magazine,
features, among other stories about the major recent scientific results,
a story about measuring the gravitation constant G (according to
Newton's law, the attraction force of a body with mass M at a distance R
is GM/R^2). Due to the fact that on Earth, the gravitational interaction
between bodies is much weaker than any other interaction, this constant is
the worst known among the fundamental physical constants. What is even worse,
different known measurements of G seem to be inconsistent: there are
several measurement results with accuracy estimates; each gives an
interval of possible values of G, so, ideally, the actual value of G
must be in all of them, but ... these intervals have no common points.
Physicists and applied mathematicians from Wuppertal, Germany,
led by Prof. Dr. H. Mayer (Physics) and Prof. Dr. B. Lang (Math),
analyzed this situation and discovered that this seeming inconsistency
is caused, partially, by neglecting certain physical sources of error,
but mainly, by using approximate error estimation techniques for data
processing algorithms, techniques that often underestimate the
resulting error. Instead, they propose to use computations with
automatic result verification (in particular, interval methods).
The paper by B. Lang and co-authors will appear in No. 3 (1996) of
"Reliable Computing"; the author's email is lang@math.uni-wuppertal.de.
A brief description of this application is placed on the interval Website
http://cs.utep.edu/interval-comp/main.html
(this website also has information about the journal).
This is the second time in half a year that a result using interval
computations is featured as one of the major scientific breakthroughs:
the previous was the result about the double bubble featured last November.

Subject: Special Issue of IEEE Transactions on Image Processing
CALL FOR PAPERS
SPECIAL ISSUE ON PARTIAL DIFFERENTIAL EQUATIONS (PDE's) AND
GEOMETRY-DRIVEN DIFFUSION IN IMAGE PROCESSING AND ANALYSIS
IEEE Transactions on Image Processing
A special issue of the IEEE Transactions on Image Processing will
be devoted to the topic of Partial Differential Equations (PDE's) and
Geometry-Driven Diffusion in Image Processing and Analysis.
This relatively new area provides a strong theoretical framework for
image processing and analysis. Attention to these methods
has increased lately due to important theoretical and practical
results that have been obtained. The basic idea is to obtain
the processed image as the solution of PDE's, being in general
the initial condition a function of the original image. The PDE approach
permits to unify and extend existent algorithms, as well as to
develop novel ones. Extensive research on numerical analysis
allows the implementation of these equations, obtaining accurate
image processing algorithms. Authors are encouraged to submit original,
unpublished research papers in this area. Papers on both theory
and applications will be welcome. Topics of interest include but
are not limited to
* scale-space theory
* anisotropic diffusion
* vector-valued diffusion
* systems of coupled PDE's
* PDE based segmentation, image and video enhancement, shape analysis
* axiomatic and PDE based theoretical approaches to image analysis
* variational and PDE's-from-energy approaches to image processing
* curve and surface evolution
* PDE's in hybrid systems
* comparison of models
* image and noise models and adaptation of PDE's
* implementations and numerical analysis
* applications
The special issue will be edited by the following team of guest editors:

I would like to announce the 1996 Summer Program for Women in Mathematics
(SPWM) at The George Washington University.
SPWM is a four-week (June 29, 1996 through July 27, 1996) intensive program
for mathematically-talented undergraduate women who are completing their
junior year and may be contemplating graduate study in the mathematical
sciences. The goals of this program are to communicate an enthusiasm for
mathematics, to develop research skills, to cultivate mathematical
self-confidence and independence, and to promote success in graduate school.
Sixteen women will be selected. Each will receive a travel allowance,
campus room and board, and a stipend of $1,250.
The application deadline is April 1. Early applications are encouraged.
For further information, contact the co-directors:

Subject: Women in Mathematics Workshop
Application DEADLINE for the AWM Workshop
for WOMEN Graduate Students and Postdoctoral Mathematicians
at SIAM, Kansas City, Mo., July 22 & 23, 1996
has been EXTENDED to
FRIDAY, MARCH 8, 1996
Applicant who meet eligibility requirements and are selected to
participant in the AWM Workshop/Minisymposium will received FULL
transportation reimbursement and 3 days subsistence.
WORKSHOP
for WOMEN Graduate Students and Postdoctoral Mathematicians
supported by the Office of Naval Research and
the Association for Women in Mathematics
Over the past seven years, the Association for Women in Mathematics
has held a series of workshops for women graduate students and recent
Ph.D's (referred to as "postdocs" below) in conjunction with major
mathematics meetings.
WHEN: The NEXT WORKSHOP in the series will be held in conjunction
with the Society for Industrial and Applied Mathematics (SIAM) Annual
Meeting in Kansas City, Missouri, July 22-26, 1996. This workshop
will be held during the first TWO days of the meeting on Monday, July
22 and Tuesday, July 23, 1996.
WORKSHOP: The workshop will consist of two poster sessions, four
minisymposia, a panel on careers, a panel on government funding and an
after dinner keynote speaker. The poster sessions include all areas
of research in applied mathematics. Each minisymposium will have a
definite focus. The first minisymposium will include four talks by
experienced researchers about specific communication skills, written
and oral, that are helpful in effective presentation of technical
results. The three remaining minisymposia will focus on the research
areas of control theory, inverse problems, and dynamical systems.
Applications for funding must be received by AWM by March 1, 1996.
Graduate students participants will present their research in a poster
session. Postdocs (those within five years of their Ph.D.) will speak
in one of the three AWM research minisymposia or in one of the other
minisymposia or contributed paper sessions at the SIAM meeting. All
mathematicians (female and male) are invited to attend the entire
program. AWM will offer funding for travel and 3-days subsistence for
approximately 20 graduate students and 20 postdocs. Departments are
urged to help graduate students and postdocs obtain some supplementary
institutional support to attend the Workshop and the associated
meetings.
ELIGIBILITY: To be eligible for funding, GRADUATE STUDENTS must have
begun work on a thesis problem. Applications should include a cover
letter, an abstract of their work, a curriculum vitae, and a
supporting letter of recommendation from a faculty member or research
mathematician. Applications from POSTDOCS should include a cover
letter, an abstract of their work, curriculum vitae, and may also
include a letter of recommendation. Letters of support are
encouraged. The word "POSTDOC" refers to any mathematician who has
received her Ph.D. within the last five years, whether or not she
currently holds a postdoctoral or other academic position. All funded
participants are invited and strongly encouraged to attend the full
AWM two-day program. All non-U.S. citizens applicants must have a
current U.S. address.
