Mathematical Challenges in Spatial Ecology

Ever since the 1798 essay of Thomas Malthus, the study of how populations interact with the environment has involved mathematical considerations. The author surveys current progress and problems in understanding the role of space in mathematical models of populations.

Nonlinear Phenomena in Complex Systems

Nonlinear Phenomena in Complex Systems is a quarterly journal, which publishes original research papers and reviews. The primary objective of Nonlinear Phenomena in Complex Systems (NPCS) is to provide a single forum for this interdisciplinary area to strengthen links between basic and applied research, theoretical and experimental methods relating to nonlinear dynamics of complex systems encountered in the natural and social sciences. Its goal is to bring together, in one periodical, significant papers of high quality on all aspects of nonlinear dynamics, including phenomena, modelling, and complexity, thereby providing a focus and catalyst for the timely dissemination and cross-fertilization of new ideas, principles, and techniques across a broad interdisciplinary front. The scope of this international journal includes experiment, computational, and theoretical aspects of phase transitions, critical phenomena, self-organization, bifurcations, chaos, fluctuation phenomena, pattern formation, fractals and complexity in physics, mathematics, chemistry, engineering, biology, social and economic sciences and the other areas of Scientific endeavour.

Special Issue Dynamical Sytems: an International Journal - Non-smooth Dynamical Systems: theory and applications

This Special Issue intends to address the growing interest in the analysis of systems modelled by sets of non-smooth differential equations and maps. These include a wide variety of physical and engineering devices. Examples include power electronic converters, mechanical systems with impacts and friction, hybrid and relay feedback control schemes, walking mechanisms and many others. The study of discontinuous and nonsmooth systems is rapidly becoming an active research area within the dynamical systems community and deserves a wider attention. A special issue devoted to this topic is hereby proposed for the journal 'Dynamical Systems: an International Journal'.

Original research papers are solicited in the following areas:

Analysis and classification of solutions and bifurcations in non-smooth dynamical systems, Numerical analysis for the simulation of non-smooth systems, Modeling of non-smooth and discontinuous events in physical and engineering systems, Characterisation of dynamics of specific piecewise-smooth and discontinuous systems of relevance in applications.

Review papers on topics within the scope of the special issue may also be considered. Authors are welcome to submit an abstract in advance of the paper itself if they would like advice as to its suitability for this special issue.

The Guest Editors for this Special Issue will be: 
Dr. Mario di Bernardo, e-mail: m.dibernardo@bristol.ac.uk 
Prof. Alan Champneys, e-mail: a.r.champneys@bristol.ac.uk and 
Dr. Martin Homer, e-mail: martin.homer@bristol.ac.uk

Contributions should be submitted electronically by sending a PDF or Postscript version of the manuscript together with the contact details of the corresponding author to Dr. Mario di Bernardo, e-mail: M.diBernardo@bristol.ac.uk

All manuscripts will be subject to peer review and should be submitted by 30th April, 2002. Manuscripts will normally be no more than 20 pages long and conform to the standards as indicated on the journal website.


Special Issue IEEE Transactions on Circuits and Systems - Applications of Chaos in Modern Communication Systems

This Special Issue intends to address the growing role of nonlinear dynamics and chaos theory in modern communication systems. The focus is on those elements and/or algorithms in the transmitter-receiver chain which exploit properties of nonlinear systems and chaos. Chaotic signals are characterized by random-like behavior in the time domain, and by continuous broadband power spectrum in the frequency domain. These properties have emerged in several applications in the communication field. Chaos-based communications systems are now in a mature state of development and several possible schemes have been proposed and characterized. A crucial step towards the implementation of practical communication systems includes a good bit-error-rate (BER) performance in the presence of noise and distortion, resistance to multipath propagation, and multi-user capabilities. In these areas there has been recently a great research activity. The aim of this Special Issue is to identify those ide! as which might lead to some real engineering applications.

Original research and tutorial papers are solicited in the following areas:
