Subject: Jim Ortega, 1932 - 2008

James M. Ortega (1932-2008)

Jim Ortega, a leader in scientific computing, died October 24, 2008
in Melbourne Beach, Florida.

Jim Ortega received a PhD in Mathematics from Stanford University in
1962 under George Forsythe. He joined the University of Maryland in
1964 and became professor of Computer Science, Mathematics, and
Applied Mathematics in 1969. At Maryland he produced the classic
"Iterative Solutions of non-Linear Equations in Several Variables"
(Academic Press, 1970), in collaboration with Werner Rheinboldt.

>From 1973-77 he was the founding director of ICASE ("Institute for
Computer Applications in Science and Engineering") at NASA's research
center in Langley, Virginia, and then he became head of the
Mathematics Department at N.C. State University in 1977.

Jim Ortega joined the University of Virginia in 1979 as Charles
Henderson professor and chairman of Applied Mathematics and Computer
Science. In addition to advising 14 PhD students at UVA, he wrote 9
books during his tenure there. He retired in 1996.

Jim moved to Melbourne Beach after his retirement and followed a
long-time interest by attending classes in astrophysics at the Florida
Institute of Technology. He contacted Terry Oswalt, chair of the
Physics & Space Sciences Department at FIT, after learning from a
newspaper article that the department was trying to obtain a
telescope. This contact eventually led to a donation of $150,000 by
Jim and Sarah Ortega to help finance a 32" telescope, now known as the
Ortega reflecting telescope. The Ortegas also established a fund to
benefit students.

He had a huge impact on his students, and on those that knew him.
He will be missed.

(Max Planck Institute for Mathematics in the Sciences,

Time: March 2nd to March 6th, 2009
Deadline for registration: February 6th, 2009
Topic: Hierarchical matrices can be a useful tool for the treatment of
integral operators as well as the solution of linear systems
arising in the discretisation of elliptic partial differential
Moreover, the representation of matrices in the hierarchical
matrix format is suitable for the efficient solution of matrix

The aim of this winterschool is to teach the necessary
theoretical foundations of hierarchical matrices, but most of
all the efficient implementation of the algorithms. The practical
realisation on the computer will be the topic of exercise courses
in the afternoon.
The participants will use the HLib library in order to assemble
and solve BEM and FEM systems. Lecture notes are available in
electronic form.

Subject: SIAM/ACM Geometric and Physical Modeling, San Francisco, Oct 2009


incorporating the 2009 SIAM Conference on Geometric Design and the
2009 ACM Symposium on Solid and Physical Modeling

October 5-8, 2009
San Francisco, California, USA
Hilton San Francisco Financial District

Conference website:

In ACM SPM tradition, the conference will include a track for submission
of peer-reviewed technical papers for those wishing rigorous peer review
and published proceedings. In addition, in the tradition of previous
SIAM GD events, abstracts for minisymposia and contributed talks/posters
are solicited. As a rule, no conference participant will be allowed to
submit the same abstract to more than one track, nor to give more than
one minisymposium or contributed talk.

Peer-reviewed Technical Papers for Published Proceedings

Proceedings papers should present previously unpublished, original
results that are not simultaneously submitted elsewhere. All papers will
be rigorously peer-reviewed by members of the Program Committee.
Each accepted paper will appear in the conference proceedings published
by ACM Press, and be presented in a talk of approximately 30 minutes.
Some submissions may be accepted for the conference proceedings as a
short paper not exceeding 6 pages, and presented in a poster session.
Selected papers of outstanding quality may be invited to be considered
for publication in archival journals after the conference.


A minisymposium consists of at least four 25-minute presentations, with
an additional five minutes for discussion after each presentation.
Prospective minisymposium organizers are asked to submit a proposal
consisting of a title, a description (not to exceed 100 words), and a
list of speakers and titles of their presentations.
Each minisymposium speaker should submit a 75-word abstract.
All proposals for minisymposia will be checked for relevance to the
conference by the Program Chairs. The number of minisymposia may be
limited to retain an acceptable level of parallelism in the conference

Contributed Presentations in Lecture or Poster Format

Contributed presentations in lecture or poster format are invited in all
areas consistent with the conference themes. A lecture format involves a
15-minute oral presentation with an additional 5 minutes for discussion.
A poster format involves the use of non-electronic visual aids for
mounting on a poster board. A poster session is two hours long.
Each contributor, either for a lecture or a poster, must submit a title
and a brief abstract not to exceed 75 words. All abstracts for
contributed presentations will be checked for relevance to the
conference by the Program Chairs.

Abstract submissions for proceedings: March 1, 2009 (required to
expedite the review process)
Full paper submissions for proceedings: March 16, 2009
