Centre for Nonlinear Studies, Los Alamos National Laboratory
Aim The conference on Nonlinear Waves and
Solitons in Physical Systems will provide a forum for
experimental and theoretical scientists to
collaborate in understanding physical systems where nonlinear
waves and solitons play a central role. The research and
expository talks will review recent advances in analytical,
experimental and computational research in the dynamics of
water waves, nonlinear optics in communication systems and
lasers, patterns and coherence in complex fluids,
discrete lattice systems and the evolution of nonlinear
reaction diffusion waves in thin films. The central
interdisciplinary theme will be to identify
promising new directions for research in these areas.
Physica D will publish
a special issue dedicated to Nonlinear Waves and Solitons in
Physical Systems, highlighting the most exciting research
in nonlinear waves.

Exploiting Chaos in Signal Processing, 21 May 1997.
There are many difficulties in signal processing which linear
techniques fail to address satisfactorily. It is a commonly held
view that these problems may have solutions by means of nonlinear
methods. The rise in neural network concepts is largely fuelled
by this promise. This colloquium will explore the implications of
chaos theory for signal processing.
At the turn of the century Poincare began the development of a
geometrical description of nonlinear dynamical systems. This work
was continued by Birkhoff in the early part of this century, but it
was not until the advent of powerful digital computers that the
power of these techniques became apparent. The last decade has seen
an explosion of interest in nonlinear dynamical systems because of
the realisation that low dimensional systems can exhibit extremely
complex behaviour. The original motivation for much of the work was
the need to utilise these new mathematical ideas to interpret
experimental data. Recently, however, it has become clear
that these methods can provide a new approach to signal processing
which will offer enhanced performance over existing techniques.
Colloquium Aim: The aim of this colloquium is to
discuss the implications of chaos theory for understanding and
developing nonlinear signal processing devices and algorithms in
a range of applications. It is hoped that contributions covering,
but not limited to, the areas of bio-medical signal processing,
seismic signal restoration, image processing
and communications will be forthcoming.

elementary introduction to solitons and an up-to-date panorama of
this scientifically exciting and technologically promising field of
research, the methods discussed in this School will range from
basic concepts and experiments in soliton science to various
applications and recent developments. The School is also intended
to stimulate useful scientific exchanges and favour the creation

The Mathematical Biology of Pattern and Process,
6-9 April 1998.
Centre for Mathematical Biology, University of Bath.
Announcement: The workshop is an interdisciplinary
meeting of biologists and mathematicians focused on effects of
individual behavioural decisions of animals on population dynamics.
Such decisions include, for example: optimal prey selection
(i.e., prey model), optimal path selection (i.e., path model),
ideal free distribution, optimal antipredatory behaviour
(including effect of refuges), various trade-offs in behaviour of
parasitoids (superparasitism, host-feeding etc.) and other game
Although it is generally believed that such behavioural decisions
have a strong impact on population dynamics, qualitative work on
effects of these behavioural choices on population dynamics seems to
have started quite recently. The workshop should bring together
scientists working in behavioural ecology, and/or in population
biology both from theoretical and experimental point of view
(including mathematicians and theoretical population biologists).
Moreover, the workshop is also intended to attract some bright young
mathematically orientated participants for whom the meeting would
provide a starting point for their PhD thesis in theoretical
