Recently, several approaches for communications using chaos have been presented, often showing less than acceptable performance. In this paper, a short introduction to the topic is given, and it is shown that such methods can be efficient—if the informatio ...
This work is dedicated to the study of models of quantum chaos. It is clear that one cannot define chaos in quantum mechanics the same way it is defined in classical dynamics. The classical definition of chaos relies upon the ideas of sensitive dependence ...
SystemC-AMS currently offers modelling formalisms with specialised solvers mainly focussing on the electrical domain. There is a need to improve its modelling capabilities concerning conservative continuous time systems involving the interaction of several ...
Dynamic textures are sequences of images showing temporal regularity; they can be found in videos representing smoke, flames, flowing water, or moving grass, for instance. Recently, one method based on linear dynamic system theory was proposed to synthesiz ...
The paper presents numerical investigations of decelerated swirling flows specific to hydraulic turbines draft tube cone, within the framework of axisymmetric flow models. First, we investigate the behaviour of a Burgers vortex in a diffuser as the swirl i ...

In this thesis a previously developed framework for modelling diversity of approximately periodic time series is considered. In this framework the diversity is modelled deterministically, exploiting the irregularity of chaos. This is an alternative to othe ...
In this paper a class of discretized piecewise linear chaotic maps of a very high dimensions are used for communication over a noisy channel. An information payload that is sent over a channel is controlled in the transmitter and is related to the symbolic ...
In this thesis, a new class of codes on graphs based on chaotic dynamical systems are proposed. In particular, trellis coded modulation and iteratively decodable codes on graphs are studied. The codes are designed by controlling symbolic dynamics of chaoti ...
Digital Holographic Microscopes (DHM) enables recording the whole information necessary to provide real time nanometric vertical displacement measurements with a single image acquisition. The use of fast acquisition camera or stroboscopic acquisition mode ...
This paper presents a robotic arm controller for reaching motions. This controller applies two principles inspired by current theories of human reaching motions, namely the multi-referential control of movements and the dynamical system approach to biologi ...
