UK Nonlinear News, February 1999
The Lewis Fry Richardson Medal of the European Geophysical Society is awarded for work on nonlinear processes in geophysics. The award for 1999 has been made to Raymond Hide (Emeritus Professor of Physics at the University of Oxford, UK) in recognition of his "pioneering experimental and theoretical studies of the nonlinear dynamics of rotating fluids, and their application to understanding the dynamics of planetary atmospheres and interiors".

I am interested in discrete versions of the Boltzmann equation with the "full" scattering term, i.e., without the relaxation time approximation. I would like to correspond with researchers working in this area.

Version 3.0 of Visual Recurrence Analysis (VRA) for Windows 95, 98 and NT has been released.
VRA is a free software for topological analysis and qualitative assessment of (chaotic) time series. It can detect hidden patterns and determinism in time series using graphical device known as the Recurrence Plot (RP). Before a RP is constructed, VRA expands a given one-dimensional time series into a higher-dimensional space, in which the dynamic of the underlying generator takes place. This is done using a technique called "delayed coordinate embedding", which recreates a phase space portrait of the dynamical system under study from a single data series. VRA is very fast and highly interactive. Extensive online help is provided. Many qualitative and quantitative analysis tools have been added.
VRA version 3.0 remains free provided that you use it for educational/ academic/research purposes.
I welcome any questions and suggestions you may have regarding VRA software and its use. Download VRA from http://www2.netcom.com/~eugenek/page6.html

Software and tutorials are available for recurrence quantification analysis (RQA) and cross recurrence quantification through links at http://www.rushu.rush.edu/molbio/physiozbi.html. RQA is an extension of recurrence plots (RP) in that it quantifies several features obtained in recurrence plots, including an approximate measure of Liapunov exponents. Whereas RPs provide visual hints of dynamics, they are liable to misinterpretation. RQA overcomes this difficulty by quantifying %recurrence, %determinism, entropy (of line segment lengths), lmax (Liapunov estimation), and trend (approx. derivative). Cross recurrence quantification provides similar information between 2 ordered dynamics.

The posts of president and vice-president of the United Kingdom and Republic of Ireland SIAM section are determined by a ballot of the section members. In response to my call for nominations (sent out 15/11/98), I am pleased to inform you that three valid nominations have been received.
One nomination for president:
Trevor Stuart (Imperial College)
Two nominations for vice-president (in alphabetical order)
Desmond Higham (University of Strathclyde)
Paul Martin (University of Manchester)
The result will be declared at the annual meeting on 8th January at Imperial College, and the new officers will be in post until 30/3/2001.

With this issue Sakse Orstavik steps down as an editor of UK Nonlinear News. Sakse starts a job with Barclays Capital in July and has decided to concentrate on finishing his PhD.
Sakse joined the editorial team with issue 8 (May 1997). In addition to maintaining the UK Nonlinear News mailing list and helping out with the behind-the-scenes preparation for each issue he also found time to write several articles for UK Nonlinear News:
We thank Sakse for all his hard work during his time as an editor.
UK Nonlinear News welcomes Cliburn Chan to its editorial board. Cliburn is a PhD student at the Centre for Nonlinear Dynamics and its Applications (UCL) working under the supervision of Jaroslav Stark and Andrew George at Hammersmith Hospital on cytokine networks, funded by ORS and UCL scholarships.
The site http://www.theorem.net/control.html collects several resources for control theory and engineering, including the complete and indexed collections of the Electronic Newsletter in Control and the Nonlinear Control Abstracts, as well as links to books, journals, software, technical societies, conference listings, and other web sites.

The meeting starts at 12.00noon and lasts until 5.30pm with a break
for lunch as well as tea and biscuits. This start time should allow
participants from Warwick, QMW, UCL and Surrey to reach us by
train. (Note that parking in Cambridge is limited and expensive).
Coventry to Cambridge (via Nuneaton) leaves 8:24, arrives 11:35.
London (Kings Cross) to Cambridge leaves 10:15 and 10:45, arrives
Details of how to find King's College are best obtained from the King's Web
Site. Further details can be provided if necessary.
All are welcome, especially graduate students, and travel expenses of those
from QMW, UCL, Warwick and Surrey can be reimbursed by asking Robert MacKay
at the meeting - this is from a grant provided by the London Mathematical
