Subject: Obituary: Jack Todd

John Todd, Pioneer of 20th-Century Mathematics, Dies

John Todd, one of the pioneers of numerical analysis, died Thursday, June
21, at his home in Pasadena, California. He was 96. Todd's legacy and impact
on modern-day mathematics can be seen in his contributions to analysis,
linear algebra, and computation. His work was a precursor to and helped
shape the foundation for today's computer science field. A professor
at the California Institute of Technology, Todd developed the
first undergraduate courses at Caltech in numerical analysis and numerical
algebra, which play a key role in scientific computing.

Subject: New CADNA web site

The new OPEN source version of the CADNA library is now available at
"". It is completely free and normally available
for any Unix systeme.

For reminding, The CADNA library allows to estimate the accuracy of each
computed result and to give to users a tool for a real numerical
debugging. You will find all informations on the Web site

Subject: SPRNG Random Number Generators available on the Cell

Dear Colleagues,

I am happy to inform you that the SPRNG Parallel Random Number
Generator libraries, Version 1.0, have been ported to the Cell
processor by K. Gunaranjan at Sri Sathya Sai University, India. We
have not made them available from the SPRNG web pages yet. You may
obtain them by directly contacting K. Gunaranjan at

Let me also clarify the differences between the different version
of SPRNG here, since many users appear to need some clarification on
this. All the random number generators in all the SPRNG versions are
identical, and call the code implemented in SPRNG 1.0. They differ
mainly on their interfaces.

SPRNG 1.0 allows an application to call only one type of random number
generator in any given run. Of course, users may use several streams
and variants in the same application. This version will be ideal for a
typical C or Fortran application user. C++ users may also use this,
but calling sprng like any C function.

SPRNG 2.0 permits use of different types of random number generators
in the same application, at the cost of some decrease in speed. This
will be particularly useful to users who are trying to develop new
types of random number generators by combining different generators.

SPRNG 4.0 provides C++ wrappers to the SPRNG 2.0 library.

- Ashok

Subject: New book, Data Clustering: Theory, Algorithms, and Applications

Data Clustering: Theory, Algorithms, and Applications
Guojun Gan, Chaoqun Ma, and Jianhong Wu
ASA-SIAM Series on Statistics and Applied Probability 20

Cluster analysis is an unsupervised process that divides a set of objects into
homogeneous groups. This book starts with basic information on cluster analysis,
including the classification of data and the corresponding similarity measures,
followed by the presentation of over 50 clustering algorithms in groups according
to some specific baseline methodologies such as hierarchical, center-based, and
search-based methods. As a result, readers and users can easily identify an
appropriate algorithm for their applications and compare novel ideas with
existing results. The book also provides examples of clustering applications
to illustrate the advantages and shortcomings of different clustering
architectures and algorithms. Application areas include pattern recognition,
artificial intelligence, information technology, image processing, biology,
psychology, and marketing. Readers also learn how to perform cluster analysis
with the C/C++ and MATLAB® programming languages.

Subject: PhD Studentship, Laboratoirede Mathématiques Appliquées, Pau, France

The aim of this phd is to develop a new approach for the
discretization of realistic models for polymer flows. The theoretical
part of the thesis will be accompanied by the development of a
computational code for the numerical simulation of nonisothermal
non-newtonian flows with nonlinear differential laws. This software
will be based on the incompressible flow solvers and related tools
developed at LMA. This thesis is part of an interdisciplinary
collaboration. For more information see

Start date: autumn 2007.
