Subject: Magolu monga Made

We have the sad news that Magolu monga Made passed away on the 15th July
2010,
at the age of 53. He is survived by his wife and their six children.

He was born in Congo, where he made his master studies, and was given
a grant in the late 80's to undertake a thesis at the Universite Libre de
Bruxelles. He made also several post-doc stays at Nijmegen, Utrecht and
CERFACS, and we anticipate that the unexpected news of his death will
be terribly sad for all his former colleagues, as it is for us.
Magolu was indeed universally appreciated as a kind person, and
the world has just lost one of the wisest man. His name, as he pleased
to tell, means: "springs of clear water issued from a lake of quietness";
and this indeed depicts him perfectly as all his friends will confirm.

>From the scientific viewpoint, Magolu was an active researcher in the
field of (block) incomplete factorization algorithms, of the associated
iterative methods and of their parallelization. He also considered their
application to acoustic problems where his results represented a true
breakthrough, not yet appropriately acknowledged today (he was among
the first to consider adding imaginary perturbations before applying
preconditioning techniques, a methods nowadays better known under the name
of "shifted Laplacian preconditioning"). He planned to extend
his results to vibro-acoustic problems as you can still read on his
webpage.

Subject: New e-book: Exponential Data Fitting and its Applications

V. Pereyra and G. Scherer (Editors)
Bentham Books

http://www.bentham.org/ebooks/9781608050482/index.htm

Exponential approximations are ubiquitous in different fields of
scientific computing.
There are many reasons for their success in modeling various phenomena.
Processes that are modeled by linear differential equations with constant
coefficients and Fourier expansions are just two such reasons.
In particular, wave propagation problems in their many expressions
are heavily represented, because wave fronts in the far field are plane,
and plane waves are described by complex exponentials.
In this volume we consider the least squares approximation of data
by linear combinations of real or complex exponentials. In the first
chapter, Pereyra and Scherer discuss the problem from a mathematical
and numerical point of view, giving an historical perspective and
detailed description of some of the most successful and frequently
used methods. The Variable Projection (VP) method, introduced
in 1973 by Golub and Pereyra, extending the initial contribution of
Gutman, Pereyra and Scolnik, is carefully discussed as the nonlinear
least squares method of choice. Prony's method and its more numerically
stable variants are also discussed, as they are also frequently
used in many applications. Some comparisons and discussion of advantages
and shortcomings are included.
Various applications are then considered by experts in their respective
fields. A common thread in these chapters is a fairly comprehensive
presentation of the physical problem, then a discussion of the
methods used by that particular community. Among these methods we
find prominently the ones described in Chapter~1 and some of their
variations.

This is a modified version of the successful 3-day course we held last year;
based on popular demand we have added lectures on parallel debugging and
verification techniques.
Details and registration (required, but free to students, faculty, staff,
and affiliates) are available at
http://parlab.eecs.berkeley.edu/2010bootcamp
