ATTENTION ATTENDEES

SIAM Conference on Linear Algebra in
Signals, Systems and Control


November 5-8, 1990, San Francisco, CA

Due to some unavoidable circumstances, Professor Ake Bjorck is unable to give
his invited presentation scheduled for 8:30 AM, Tuesday, November 6. In his
place, Professor Gene H. Golub, Stanford University, will give the following
presentation:

Orthogonal Polynomials and Least Squares


In this talk, we discuss two topics whose solution has a common tool of
development. Orthogonal polynomials over a finite set of points come up in
many applications. The polynomials are determined by a three-term recurrence
relationship. We discuss the problem of updating and downdating the recurrence
relatioships. Another important problem is to solve a linear least squares
problem with a quadratic constraint on the solution. The data matrix may be of
large dimension so that it is not possible to compute the associated SVD. We
describe an algorithm for getting upper and lower bounds on the Lagrange
multiplier. Both problems are solved through the method of modified moments
and Gauss quadrature.

Time of presentation: 8:30 AM, Tuesday, November 6, 1990

Room: International Ballroom, Cathedral Hill Hotel

Subject: A Classic Book Republished

I'm pleased to announce that the MAA SPECTRUM book series I edit has just
published a slightly revised version of Forman Acton's classic NUMERICAL
METHODS THAT usually WORK. Gene Golub and others supported our decision
to reissue this; I for one have always found it delightful, although
students always complained that it didn't tell them what to do but kept
pointing out how things could go wrong. Acton believes that numerical
computation is an art, and he exhorts the reader "to go forth to make
fruitful mistakes". I wish I knew how to restrict my mistakes to fruitful
ones, but I know that getting this book is no mistake at all. Happy
reading!

Jim Daniel

P.S. I do NOT get royalties or a fee for this or any other SPECTRUM book.

POSTDOCTORAL/GRADUATE FELLOWSHIPS IN SCIENTIFIC COMPUTING AND VISUALIZATION

Applied Research Branch
Numerical Aerodynamic Simulation Systems Division
NASA Ames Research Center
Moffett Field, CA 94035


The Applied Research Branch of the Numerical Aerodynamic Simulation (NAS)
Systems Division invites outstanding candidates to apply for postdoctoral
and/or graduate fellowships in scientific computing and visualization.
Subject to final approval of funding the award of two fellowships
is anticipated. One fellowship will be in the area of scientific
computing on parallel supercomputers, the other on scientific visualization
and advanced user interfaces.

The Numerical Aerodynamic Simulation (NAS) Systems Division at NASA
Ames Research Center operates a national supercomputer center, with a
4-processor Cray-2, an 8-processor Cray Y-MP, a high-speed
communications network, and high-performance color graphics workstations.

Recently NAS established the Applied Research Branch, one of whose
missions is to perform state-of-the-art research in highly parallel
computation for fluid dynamics applications. Our organization now
operates a Connection Machine CM-2, with 32,768 processing nodes and
floating-point hardware and an Intel Touchstone Gamma Prototype (iPSC/860)
with 128 i860 processors. Each researcher in the Applied Research Branch
is assigned a dedicated workstation with performance characteristics
of at least a Silicon Graphics IRIS 4D/25 class. Researchers in the
visualization area will have access to SGI 320 VGX workstations.

The purposes of the fellowship in scientific computing is to promote
innovative research in algorithms, software, or tools on advanced
computer architectures. The successful candidate will be expected
to conduct a program of personal research and participate with NASA
scientists in the actual application of his/her research project.

The purpose of the visualization fellowship is to promote and stimulate
research in the areas of volumetric rendering, virtual environments,
parallel and distributed graphics, applications of computational geometry,
field topology extraction and display, and integrated visualization
environments for supercomputing.

An important element of both fellowships is
to facilitate technology transfer from our research group into the NAS
user community. Familiarity with large scale computational
aerosciences applications, and the ability to work in an interdisciplinary
environment are desirable assets for a successful applicant.

The fellowships are for a term of one year, renewable for a second year.
Benefits of the Fellowship include a competitive salary, fringe benefits,
travel opportunities, access to state-of-the-art computational facilities
(including both parallel architectures and high-performance personal
workstations), and collaborative research opportunities in a very active
research program in advanced scientific computing. Competition for the
appointment is open to U.S. citizens and permanent residents.
Postdoctoral applicants should have completed a doctoral degree in
computer science, applied mathematics, mechanical engineering, aeronautical
engineering, or a related discipline within three years prior to the
appointment and have a strong background and research interest in
large-scale scientific computing. Graduate fellowship applicants should
have completed all requirements for their degree, except the completion
of their thesis. A graduate fellowship will include continued support for
the completion of the Ph.D. thesis in coordination with the applicant's
university.

Applicants should send a resume, a research plan, including a statement
how the proposed project could be applied to computational problems
of interest to NASA, and the names of three references to Horst D. Simon,
Mail Stop T045-1, NASA Ames Research Center, Moffett Field, CA 94035.
The deadline for applications is December 14, 1990, and the selection
committee's decision will be announced in early 1991. The position will
commence in 1991.
