Subject: Leslie Fox Prize

Call for Papers

The Twelfth Leslie Fox Prize meeting will take place on Monday,
June 27th 2005, at the Department of Mathematics, University of Dundee.
The Numerical Analysis Conference 2005 will follow from 28th June-
1st July, 2005 (see

Entries for the Twelfth Leslie Fox Prize competition should now be
submitted. Any person who is less than 31 years old on January 1st,
2005 and has not already won a first prize is eligible. Each entry
should consist of a paper, describing some of the candidate's
research, that is suitable for a 40 minute lecture at a numerical
analysis symposium. Whether or not the work has been published or
accepted for publication is irrelevant, but no person may submit more
than one paper. Candidates from previous competitions are encouraged
to enter.

The entries will be considered by an Adjudicating Committee: its
members are Prof. Alastair Spence (Bath, Chairman), Prof. Endre
Suli (Oxford) and Prof. Andrew Stuart (Warwick). Particular attention will
be given to the originality and quality of each paper, and to the
suitability of the material for a 40 minute talk to a general audience
of numerical analysts. Papers will be selected by the Committee by
the mid-April 2005, for presentation at the Leslie Fox Prize meeting.
Only the papers that are presented at the symposium will be eligible
for awards but, subject to this restriction, the Adjudicating Committee
may award any number of first and secondary prizes.

* Entries should be received, by the Chairman, by January 31st,
2005, either electronically as a PostScript or a pdf file or as three
hard copies by regular mail.

* Each candidate should include a statement of her/his year of
birth and should indicate that she/he would be available to present
her/his paper at the symposium.

* A joint paper may be submitted by an individual candidate if
accompanied by a statement from the co-authors agreeing to the
submission and detailing the contribution of the candidate to the

* Travel funds are not generally available to assist candidates who
attend the symposium.

* The receipt of all entries will be acknowledged.

Subject: JMSL Numerical Library Adds Neural Networks

Dear Colleagues,

I am pleased to announce the availability of The JMSL(TM) Numerical
Library Version 3.0.

The JMSL Library is a numerical analysis math and statistical library
written in 100% Java(TM) that also includes highly configurable graphics
in Java. Version 3.0 adds neural network algorithms for data mining and
forecasting with large or complex data sets. In addition to the
feed-forward neural network training and forecasting engines, the
library includes a package of classes for data mining pre-processing and
post-processing, thus facilitating the data preparation stages of the

Version 3.0 also adds algorithm functionality in the areas of
regression, cluster analysis, categorical statistics, and a new heat-map
chart type.

For more information on the JMSL Numerical Library please visit:

The IMSL Libraries include coverage of a broad range of mathematics and
statistics algorithm topics, ranging from linear algebra and transforms
to optimization and multivariate analysis. The IMSL math and statistics
libraries are available in pure Fortran, C, C#, and Java versions. The
IMSL Thread Safe Fortran, IMSL C, IMSL C#, and JMSL Libraries make
available all of the algorithms in the Libraries for thread safe
programming in multi-threaded applications.

Best Regards,
Fred Doolittle
