Subject: Web Application, The Informant
The Informant
Some of my students and I have developed a Web application called
"The Informant". Its URL is http://informant.dartmouth.edu.
This application saves key words that you provide and runs
periodic web searches (using Lycos now and other search engines
in the near future as well) on your behalf. When new web sites
are found that match your key words with a high score, you are sent
email notifying you that new material has been found. You then
reconnect to http://informant.dartmouth.edu and get a customized
page showing the new links. The service is free.
For example, suppose you are interested in sparse eigenvalue problems.
You might enter "sparse eigenvalues" as a search key word. Then
when new material relevant to "sparse eigenvalues" is found on the web
(that you have not already seen), you will get notified via email.
It works like a web clipping service essentially.
There are over 5100 registered users already from around the world
and most feedback has been very positive. The application has
been featured on Netscape's "What's New" button as well as being
the Microsoft Network "Pick of the Day". We welcome new users and
feedback about the application, especially ways in which it can
be improved.
Happy Surfing

Subject: Triangle Mesh Generator Available
Now available from Netlib:
Triangle Version 1.3
A Two-Dimensional Quality Mesh Generator and Delaunay Triangulator.
Triangle generates 2D Delaunay triangulations, Voronoi diagrams, convex
hulls, constrained Delaunay triangulations, and quality conforming
Delaunay triangulations. The latter can be generated with no small
angles, and are thus suitable for finite element analysis. Triangle
includes an implementation of Ruppert's Delaunay refinement algorithm
for 2D meshing. Users can specify constraints on minimum angle and
maximum triangle area, and can refine previously generated meshes based
on a posteriori error estimates. Support is included for holes,
concavities, internal boundaries, and intersecting segments.
The Delaunay triangulations and constrained Delaunay triangulations
produced are exact, but very little speed is sacrificed to gain this
robustness. Hence, Triangle is useful not only for finite element
practitioners, but also for computational geometers who seek a
comparison to validate the robustness of their codes against.
Triangle is accompanied by a simple X program called "Show Me", whose
purpose is to display point sets, planar straight line graphs,
triangulations, partitions, and Voronoi diagrams. It also creates
PostScript output.
Triangle is about 13,000 lines of portable C code, and Show Me about 3,400.
Each is a single, easy-to-compile file.
New features in Version 1.3: Faster file reading. Interface for calling
Triangle from another program. Attributes that allow you to determine which
(segment-bounded) region a triangle falls in. Triangle neighbor lists.
Objects can be numbered from zero. Ability to suppress insertion of new
points on the boundary, thus preserving compatibility with adjacent meshes.
Handles duplicate input points correctly.
Triangle is available through Netlib. Full online documentation for Triangle
is available on the Web at

Subject: Sparse Matrices and Pictures on the WWW
We have a new web site for viewing and downloading matrices in our sparse
matrix collection at the Univ. of Florida (including copies of matrices from
the Harwell/Boeing collection, and other collections). Each matrix has its own
web page, with two GIF images each: one of the pattern of entries (some of
are sometimes numerically zero) and one of the pattern of numerical values
(which will be in color, to denote the absolute values of the entries).
We've also included some statistical information, courtesy of the "info"
routine in SPARSKIT2. We plan on adding other information, such performance
of ordering & factorization codes, later on.
The advantage of the GIF images is that they are very small. You don't have
to download 10's of megabytes of information just to get a image of the matrix.
The site is "under construction" (aren't they all...?), but you're welcome
to take a look at what we have so far. The location may change, so for now,
simply look at my home page:
http://www.cise.ufl.edu/~davis
and follow the link from there. If you don't find it, try again later, since
we take it off-line to work on it from time to time.

Subject: Contribution to Global Optimization Software Survey
Dear Colleagues:
I have been asked to prepare a survey paper on existing global
optimization software. If you would like your software (or anyone's
work you know of) to be mentioned in this review, then please send
information (a brief ASCII description, and possibly also research
articles, user guide/info, demo disk, references, pointers to your home
page, etc. - as you find appropriate) to my address. Sending only an e-mail
message to me is certainly fine, but in case of lengthier submissions, I
would much appreciate hard copies containing supporting info.
It would be of great help, if you were kind to 'self-assess' your
contribution, esp. since I may not have your software (Some pointers:
problem types and sizes solvable, educational/professional versions,
existing interface, ease of use, test results, scope of applications...)
You are kindly asked to pass around this message to anyone whom you think
make worthwile (software related) contributions to this subject.
Since the time frame is relatively short (I was asked to do the job a few
days ago, and the submission deadline is Sept 15), your prompt reaction
will be much appreciated.
Thanks in advance for your assistance, and have a great summer!

Subject: Regional Modelling of Air Pollution in Europe
Dear Colleagues,
Some of you, people involved in large-scale applications,
might be interested to participate in the first REMAPE Workshop.
and to get contacts with groups which are actively working in
this area. REMAPE stands for Regional Modelling of Air Pollution
in Europe. This is a sub-project of EUROTRAC-2. REMAPE will
continue all activities of EUMAC (from EUROTRAC-1), but new
activities will also be started.
The workshop will be held at the University of Copenhagen,
September 26-27, 1996. All research groups, which are planning
to have projects in REMAPE, are encouraged to participate.
However, our meeting is open and we are inviting other
researchers to come and/or to give talks. All topics related
to long-range transport, meso-scale modelling, model validations,
chemical mechanisms, cloud processes, emission modelling,
simulations (related to control strategies and studies of
effects from different receptors) and large-scale computations on
modern vector and parallel computers are relevant for this workshop.
The number of particpants will be limited to no more than 75
(for technical reasons). The dead line for registration and/or
sending abstracts is August 15 1996. The registration fee will be 400 DKR.
