Subject: New Book, Parallel Algorithms for Linear Models


Parallel Algorithms for Linear Models:
Numerical Methods and Estimation Problems

Advances in Computational Economics
Volume 15

Erricos John Kontoghiorghes
Institute d' Informatique, Universite de Neuchatel,

Parallel Algorithms for Linear Models provides a complete and detailed
account of the design, analysis and implementation of parallel
algorithms for solving large-scale linear models. It investigates and
presents efficient, numerically stable algorithms for computing the
least-squares estimators and other quantities of interest on massively
parallel systems.

The monograph is in two parts. The first part consists of four
chapters and deals with the computational aspects for solving linear
models that have applicability in diverse areas. The remaining two
chapters form the second part, which concentrates on numerical and
computational methods for solving various problems associated with
seemingly unrelated regression equations (SURE) and simultaneous
equations models.

The practical issues of the parallel algorithms and the theoretical
aspects of the numerical methods will be of interest to a broad range
of researchers working in the areas of numerical and computational
methods in statistics and econometrics, parallel numerical algorithms,
parallel computing and numerical linear algebra. The aim of this
monograph is to promote research in the interface of econometrics,
computational statistics, numerical linear algebra and parallelism.

Subject: Industrial Mathematics Modeling Workshop

2000 Industrial Mathematics Modeling Workshop for
Graduate Students

July 24-August 1, 2000

Center for Research in Scientific Computation
North Carolina State University


* Expose 36 graduate students in mathematics to challenging
and exciting real-world problems arising in industrial
and government laboratory research

* Introduce students to the team approach to problem solving


During the Workshop, which will be the sixth one held at North
Carolina State University, students will be divided into six-member
teams to collaborate on "industrial mathematics" problems presented by
scientists from industry and government laboratories. These problems are
not academic exercises found in classrooms, but rather challenging,
real-world problems from industry or applied science which require fresh
new insight for their formulation and solution. Problems will be drawn
from projects under investigation by Aerospace Corporation, Fred Hutchinson
Cancer Research Center, Battelle Memorial Institute, Britannica and
Jenike and Johanson. Details regarding problems investigated in
previous years can be found at the web address listed below.


Pierre Gremaud, North Carolina State University
Zhilin Li, North Carolina State University
Ralph Smith, North Carolina State University
Hien Tran, North Carolina State University


Graduate students in mathematics, applied mathematics, or statistics
can be nominated for this program through a letter of recommendation from
a faculty member. In addition, the student is required to send a copy of
a recent transcript. The deadline for application is April 15, 2000 and
successful applicants will be notified by May 1, 2000. The Workshop will
cover all local living expenses and will provide partial support for travel
to all U.S. citizens and permanent residents (subject to available funding).
Previous workshops have been funded by the National Security Agency. In
addition, funding for the 1997-1998 and 2000 Workshops was provided by
the National Science Foundation.

Subject: Workshop on Meshfree Methods

Workshop on Meshfree Methods
at the University of Iowa
October 21, 2000

Recently, a next generation of numerical methods, collectively
called meshfree methods or meshless methods, have attracted more
and more researchers in computational sciences and engineering.
The goal of the research on the meshfree methods is to modify
the internal structure of the traditional finite element method
to make it more flexible, versatile and robust. Meshfree methods
have been successfully applied in several areas where the
application of the traditional finite element method is limited:
moving discontinuities such as cracks and shocks, multi-scale
resolution, large material distortions, etc. A large variety of
meshfree methods have been developed in the past few years,
including Element-Free Galerkin Method, hp-Clouds, Partition of
Unity Finite Element Method, Reproducing Kernel Particle Method.

A workshop on meshfree methods will be held at the University of
Iowa on Saturday, October 21, 2000. The aim of this workshop is
to bring together mathematicians, computer scientists and
engineering researchers to exchange ideas, results and applications
of the meshfree methods. The workshop will provide a good
opportunity especially for numerical analysts as many fundamental
issues related to the meshfree methods still need to be investigated.
The workshop is organized by J.S. Chen, K.K. Choi, W. Han,
S. Oliveira and D. Stewart.

Professor Ivo Babuska will give a keynote presentation. In addition,
there will be some invited presentations. If you like to present
your work on meshfree methods, or if you are interested in knowing
more about the methods, you are cordially invited to participate
the workshop.

The workshop is sponsored by IMA and NSF/DARPA. There is no
registration fee for attending the workshop. Mathematicians
from IMA Participating Institutions are eligible to receive
IMA/PI funds for the workshop expenses, where available and if
approved by the mathematician's own department chair. A limited
amount is also reserved to partially support some other participants
of the workshop.

If you are interested in giving a talk, or if you need some support
for your expense, you are encouraged to contact Weimin Han
( as early as possible, preferably before
the end of March.

Subject: Postdoctoral Position at Institut Francais du Petrole, Paris

We have grants from the EC HUMAN program, for supporting European
researchers (PhDs and post-docs) in our department, in association with
our subsidiary BEICIP-FRANLAB. These grants are available now.
In particular we propose the following postdoctoral position in
scientific computing:

Postdoctoral position:
The geological history of a basin is the result of three main parameters:
(1) deformation of the basin, such as surrection of mountains, basin
subsidence or sea level variation; (2) erosion of mountains; (3) transport and
deposition of sediment. At IFP, the study of this history is carried out
with a physical model called Dionisos. One of the most challenging
mathematical difficulties of this model lies in a diffusion equation,
subjected to a weather-limited erosion rate.

In this model, the forward problem consists in computing the geography of
the basin at issue as a function of time and space, given the previous
parameters. As for the inverse problem, it amounts to determining the three
parameters from a best-fit optimization of data coming from cores and
well logs. These data are called constraints. Moreover, these constraints
are fuzzy, in quite a precise meaning, because it is not always easy
for geologists to define the age or the water depth of a sediment.

In the context of this work, we propose to improve the inverse model in
two stages. First, we would like to quantify the error due to the
fuzziness of constraints. Second, we wish to select the best inverse numerical
method to be used the area of fuzzy optimization. Candidates should posess
some background in numerical simulation of PDE's and optimization as well as
experience in C or C++ programming. He should preferably have some interest
for geology.
