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.

I appreciate Prof. Taketomo Mitsui of Nagoya Univ. for helping with this report. ------------------------------ From: Cleve Moler Date: Mon Mar 4 13:48:22 EST 1996 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]." [1] W.F.

The old area code 615 has been changed to 423. All telephone and fax numbers at the Oak Ridge National Laboratory and the University of Tennessee at Knoxville are affected. -- Edmond Ng, Oak Ridge ------------------------------ From: Goetz Alefeld Date: Wed, 28 Feb 1996 18:49:34 +0100 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) ------------------------------ From: Marcin Paprzycki Date: Sat, 2 Mar 1996 21:51:51 -0600 (CST) 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 paprzycki_m@utpb.edu ------------------------------ From: Marcus Naraidoo Date: Tue, 27 Feb 96 11:00:18 GMT 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. ------------------------------ From: G. W. Stewart Date: Mon, 26 Feb 1996 08:53:23 -0500 (EST) 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.

(Pete) Stewart ------------------------------ From: Bobby Schnabel Date: Sun, 25 Feb 1996 17:36:56 -0700 (MST) Subject: Dennis and Schnabel Republished 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.

Floudas and P.M. Pardalos. Publication Info: Boston, MA : Kluwer Academic Publishers, 1996. Series Name: Nonconvex optimization and its applications ; v. 7 664 pp. Hardbound, ISBN: 0-7923-3838-3 Papers presented at the conference on 'State of the Art in Global Optimization: Computational Methods and Applications' held at Princeton University, April 28-30, 95 ------------------------------ From: Vladik Kreinovich Date: Sun, 3 Mar 96 10:39:44 MST 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. ------------------------------ From: Lester Ingber Date: Sat, 2 Mar 1996 09:49:56 -0800 Subject: Adaptive Simulated Annealing Archive The ASA archive now can be accessed via WWW path http://www.ingber.com/ and via anonymous ftp from ftp.ingber.com The 00index file contains an index of the other files.

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: Dr. Guillermo Sapiro Hewlett Packard Laboratories 1501 Page Mill Rd.

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.
