By Christos H. Skiadas, Ioannis Dimotikalis

This quantity includes a choice of papers steered by way of the clinical Committee that comes with the easiest papers provided within the 2d overseas convention (CHAOS2009) on Chaotic Modeling, Simulation and purposes, that used to be held in Chania, Crete, Greece, June 1-5, 2009. the purpose of the convention was once to ask and convey jointly humans operating in fascinating subject matters of chaotic modeling, nonlinear and dynamical platforms and chaotic simulation. the quantity provides theoretical and utilized contributions on chaotic platforms. Papers from numerous nonlinear research and chaotic fields are integrated and new and intensely vital effects are awarded. Emphasis was once given to the choice of works that experience major impression within the chaotic box and open new horizons to additional strengthen similar themes and matters. much more the chosen papers are addressed to an interdisciplinary viewers aiming on the huge dissemination of the speculation and perform of chaotic modeling and simulation and nonlinear technology.

Wand Local Lyapunov exponents vs. time for ij ters remain as above. 02. All other parame- Two consequences can be inferred from this result. The most direct is that the average of ALyapunov is clearly negative. We will go into detail about this on the next section. The second is that we can find an inverse proportionality between angular acceleration and the local Lyapunov exponents. Every time w hits an extreme or goes through an inflexion point, there is a corresponding peak in Local and Global Lyapunov Exponents in a Discrete Mass Waterwheel 39 the temporal dynamics of ALyapunov.

5 The filtering of atmospheric turbulent wind with Local Particle Filter Regionalization of PF seems to be a response to the problem of dimensionality. It is possible to go one step forward with pointwise PF (one PF per grid- 32 C. Baehr and O. Pannekoucke Fig. 2. Observed 1d Burgers system, on each part the true state is in blue dots and black dash lines are the EnKF without assimilation. The observations (green crosses) are pertubed by white noise. On top left, the green line is the EnKF estimation with 100 elements.

For a few years some authors have tried to use Particle Filters (PF) roughly to propose an alternative strategy. But directly applied this new approach stumbles across the problem of the dimensionality. In this paper, we present the links between EnKF and PF, we also remind that the EnKF converges but tends to a particular process and we describe the dynamical system of the nonlinear filter distribution. In the case of the PF, with a modified selection step, we investigate the effect of an increasing state space dimension for a constant number of particles.
