Subject: Pseudospectra Gateway

We are pleased to announce:

Pseudospectra Gateway,

a web site that presents examples of pseudospectra and reference material
that we hope will be useful to researchers in numerical analysis and
linear algebra as well as numerous application areas. The site includes
a bibliography with links to MathSciNet, a catalog of publicly available
software for computing pseudospectra, and a number of illustrations.

Pseudospectra are a tool for analyzing matrices and operators that are
non-normal, i.e., lacking an orthogonal basis of eigenvectors. They have
proved useful for the study of iterative methods for solving linear systems,
stability of discretizations of ODEs and PDEs, fluid dynamics, and control
theory, among other areas.

We welcome your comments and suggestions on the Pseudospectra Gateway.

Subject: New Book, Inverse and Crack Identification

New Book Announcement
Inverse and Crack Identification Problems in Engineering Mechanics

by Georgios E. Stavroulakis

Institute of Applied Mechanics, Dept. of Civil Engineering,
Carolo Wilhelmina Technical University, Braunschweig, Germany

Habilitation Thesis. Civil Engineering Dept., TU Braunschweig. The
``venia legendi'' for the scientific area of ``Mechanics'' was given
on 29th of June 2000.

Short description.

Inverse and crack identification problems are of paramount importance for
health monitoring and quality control purposes arising in critical
applications in civil, aeronautical, nuclear, and general mechanical
engineering. Mathematical modeling and the numerical study of these
problems require high competence in computational mechanics and applied
optimization. This is the first monograph which provides the reader with
all the necessary information. Delicate computational mechanics modeling,
including nonsmooth unilateral contact effects, is done using boundary
element techniques, which have a certain advantage for the construction of
parametrized mechanical models. Both elastostatic and harmonic or
transient dynamic problems are considered. The inverse problems are
formulated as output error minimization problems and they are
theoretically studied as a bilevel optimization problem, also known as a
mathematical problem with equilibrium constraints. Beyond classical
numerical optimization, soft computing tools (neural networks and genetic
algorithms) and filter algorithms are used for the numerical solution.

The book provides all the required material for the mathematical and
numerical modeling of crack identification testing procedures in statics
and dynamics and includes several thoroughly discussed applications, for
example, the impact-echo nondestructive evaluation technique.


The book will be of interest to structural and mechanical engineers
involved in nondestructive testing and quality control projects as well as
to research engineers and applied mathematicians who study and solve
related inverse problems. People working on applied optimization and soft
computing will find interesting problems to apply to their methods and all
necessary material to continue research in this field.

Subject: Europar Conference on Parallel Programming

The international Euro-Par conferences are held annually and are dedicated
to the promotion and advancement of all aspects of parallel computing.
The major themes can be divided into the broad categories of hardware,
software, algorithms, and applications for parallel computing. Euro-Par 2001
will be held in Manchester, England, on 28-31st August, 2001.

provides a forum for the presentation of the latest research results and
practical experience in parallel programming. Advances in algorithmic
and programming models, design methods, languages, and interfaces are
needed for construction of correct, portable parallel software with
predictable performance on different parallel and distributed architectures.

The topic emphasizes results which improve the process of developing
high-performance programs. Of particular interest are novel techniques
by which parallel software can be assembled from reusable parallel
components without compromising efficiency. Related to this is the
need for parallel software to adapt, both to available resources
and to the problem being solved.

Where appropriate, contributions should demonstrate quantitative
performance results in support of their claims, and address
applications not adequately handled by well-established approaches.

Topic Committee:

Global chair : Scott B Baden (University of California, San Diego, USA)
Local chair : Paul H J Kelly (Imperial College, UK)
Vice-chair : Calvin Lin (University Texas at Austin, USA)

Subject: New Institute and Faculty Positions at Stanford University

School of Engineering
Computational Mathematics and Engineering

The School of Engineering at Stanford University is developing an exciting
new school-wide initiative in computational mathematics and engineering,
taken in the broadest sense. An Institute of Computational Mathematics and
Engineering [ICME] will be formed at the school level to carry out this
initiative. It will be a key role of the institute to reach out to existing
efforts in the school in the computational mathematics and engineering
area, and then to integrate these research and curriculum activities across
Stanford's School of Engineering.

Applications are sought for tenured and tenure-track positions. The
successful applicant(s) will play a central role in bringing the Institute
into being. Appointment will be at a rank commensurate with the applicants'
experience. The School expects to make a number of appointments in
computational mathematics and engineering in the near future, to provide
significant space for Institute activities in a presently planned school
facility, and to develop computing resources, academic and research
facilities, and student fellowships and resources.

At this time two appointments may be made if suitable candidates are found,
one at a tenured senior level and one at a junior tenure-track level. The
senior candidate must be an eminent scholar in the area of computational
mathematics and engineering with vision and energy. This person must (1) be
able to demonstrate that her/his work has actual or potential applications
in the engineering context and (2) have shown leadership skills and
accomplishments. The successful applicant(s) will be expected to teach and
perform research in the computational mathematics and engineering area and
to provide leadership in expanding the School's activities in this arena.

The computational mathematics and engineering initiative will focus on
activities ranging from mathematical modeling to developing and analyzing
numerical algorithms to problems of implementation in a modern
computational environment. The journals of SIAM cover a broad range of
subjects that one can imagine being the domain of the ICME. There are a
number of classical numerical analysis and applied mathematics areas in
computational mathematics and engineering, as well as, for example,
computer-aided design, synthesis, and verification; simulation;
optimization; signal processing; computational biology; financial
engineering, etc.

Successful applicants will be appointed to a faculty position in one of the
School of Engineering's eight departments, but will dedicate a significant
portion of their time to academic and scholarly activities in the ICME. The
candidate will select her/his departments in consultation with the Dean of
Engineering. At present the School of Engineering is home to eight
departments, 219 faculty members, and over 3000 students. In fact, nearly
one quarter of all Stanford University students is enrolled in the School
of Engineering. There is an ongoing Scientific Computing and Computational
Mathematics Program (SC-CM), in which about 30 doctoral students and a
dozen masters' degree students are enrolled, and whose activities are in
the domain of computational mathematics and engineering. In addition to the
eight departments, the school has several interdisciplinary research and
teaching centers, more than 30 laboratories, and many cross-disciplinary
programs with other academic units on campus, including Medicine, Business,
Law, Earth and Physical Sciences, Linguistics, and Music.

Applicants should send a letter containing a brief statement of interest
that includes a description of their potential role in the computational
mathematics and engineering effort. Enclosures to the letter should include
a resume (including research accomplishments, teaching experience,
publications), and the names and postal and e-mail addresses of at least
five references. Senior applicants are asked to include a statement of
their vision for the planned institute. Tenure-track applicants only are
asked to enclose transcript(s) of (doctoral) graduate study. The letter and
enclosures should be sent to
Robert L. Street,
Chair, CME Search Committee &
Campbell Professor in the School of Engineering,
Environmental Fluid Mechanics Laboratory,
Stanford University, Stanford, CA 94305-4020.
Applicants are encouraged to submit their materials by April 1, 2001.
Stanford University is an equal opportunity employer and welcomes both
nominations of women and minority group members and applications from them.

Reasearch position at GMD-SCAI -- Sankt Augustin, Germany

The project SACADA - Synoptic Analysis of Chemical Constituents from Satellite
Data with 4D-Data-Assimilation within the GMD Institute for Algorithms and
Scientific Computation offers a research position. The position is for
three years. A prolongation for one additional year is possible.

The project will deliver an efficient method for chemical data assimilation
which will be used operationally at the DLR in Oberpfaffenhoven.
Based on a global weather forecast program an higher order advection scheme
or a semi-Lagrange scheme will be implemented. Special aspects of
parallelisation like width of the overlap-area have to be taken into account.
To improve the efficiency of the assimilation scheme the preconditioning method
has to be improved. Different approaches to reduce the size of co-variance
matrices have to be investigated.

Applicants should have finished computational meteorology or applied
mathematics with diploma or PhD, having experience in
partial differential equations, adjoint methods, preconditioning methods,
parallelization, numerical methods for general circulation methods.

Experience in using parallelcomputers including PC-Cluster and MPI is desired.
Knowledge in UNIX or Linux and programming skills in Fortran or C are necessary.
