Subject: Pictorial history of Gaussian elimination

Hello NA-Digest,

I have published a pictorial history of Gaussian elimination. People
who worked on "numerical linear algebra" long before it was called
that are shown, and there is a rare picture of a clay tablet that
poses one of the oldest linear algebra problems, from 2000-1600 BC.

The article can be downloaded from the Notices of the AMS. Go to the
June/July issue and follow the link to "Mathematicians of Gaussian

Subject: New OpenLB Release 0.6

The OpenLB developer team is happy to announce that a new release of
our open source Lattice Boltzmann code is available for download on
the project website .

The new release offers an automated preprocessing with built-in
voxelization from stl-files and setting of boundary conditions based
on material numbers. The usage is illustrated by the example
"examples/cylinder3d". Further, an XML reader offers an interface for
input parameters (cf. "examples/cavity2d").

Please consider to contribute code or join the developer team yourself
to strengthen the LB community by sharing your findings in an open and
easy reproducible way.

"Cryptography and Coding" is both timely and relevant. Original
research papers on all technical aspects of cryptography and coding
are solicited for submission. The proceedings will be published in the
Springer Lecture Notes in Computer Science series, and will be
available at the conference.

non-linear/non-Gaussian/non- stationary signal processing, compressive
sampling, digital communication systems, iterative estimation
(e.g. turbo codes), blind deconvolution/signal separation and
broadband systems. The last IMA conference on this subject was held in
December 2008 and in response to popular demand, the next one will be
held in December 2012. The aim of the conference is to bring together
mathematicians, statisticians and engineers with a view to exploring
recent developments and identifying fruitful avenues for further

Subject: PhD Position, Comp Seismology, ETH-Zurich

PhD opportunity in Computational Seismology
at the Swiss Seismological Service, ETH Zurich, Switzerland

The Computational Seismology Group of the Swiss Seismological Service,
ETH Zurich, invite applications for a PhD student position to work on
the seismological aspects of the ASCETE project "Advanced Simulation
of Coupled Earthquake and Tsunami Events" recently funded by the
Volkswagen Stiftung. ASCETE is a project jointly with the Dept. of
Earth and Environmental Sciences of LMU M=FCnchen, Dept. of Numerical
Methods in Geosciences of Universit=E4t Hamburg and the Institute for
Parallel and Distributed Systems of Universit=E4t Stuttgart. The main
objective of this project is to study the interaction between the
undersea earthquake source rupture process, ocean bottom
displacements, and the corresponding sea level disturbance to further
evaluate the subsequent potential tsunami generation. The problem will
be tackled through purely numerical modeling using the Discontinuos
Galerkin (DG) finite element methods. The successful candidate will
work on high-performance computational simulations of earthquake
ruptures dynamic, developing and implementing constitutive friction
laws of rate and state in the DG-method, to investigate the role of
friction laws on geometrical complex faults in subduction zones and
their effects on the ground motion and ocean bottom displacements. The
students will work in close collaboration with scientists of the
institute mentioned above and will need to spend some time in one or
more institutions of the ASCETE partners. Information on this project

The position is available from October 2011 or soon after and is
funded for three years, the anticipated time needed for obtaining a
Ph.D. degree at ETH Zurich. Applicants should have a M.Sc. or Diploma
in geosciences, physics, applied mechanics, engineering or a related
field. Strong analytical skills, experience in numerical models for
wave propagation, programming and visualization (MATLAB, FORTRAN, UNIX
shells), fluency in English and readiness to work in an international
and multidisciplinary team are essential for the position. Knowledge
of Discontinuos Galerkin finite element methods would be advantageous.

Applicants should submit, by e-mail, an application letter, curriculum
vitae, degree certificate, short statement of research interests,
names and addresses of three references to Dr. Luis A. Dalguer
(e-mail: ). Only complete applications will be
considered. The selection process starts now and will continue until
the position is filled. Preference will be given to disabled
applicants with equal qualifications. For more information, please
