Reactions to extreme events: moving threshold model
Eduardo G. Altmann, Sarah Hallerberg, Holger Kantz
In spite of precautions to avoid the harmful effects of extreme events, we experience recurrently phenomena that overcome the preventive barriers. These barriers usually increase d…
Effective dynamics in Hamiltonian systems with mixed phase space
Adilson E. Motter, Alessandro P. S. de Moura, Celso Grebogi +1
An adequate characterization of the dynamics of Hamiltonian systems at physically relevant scales has been largely lacking. Here we investigate this fundamental problem and we show…
Recurrence time analysis, long-term correlations, and extreme events
Eduardo G. Altmann, Holger Kantz
The recurrence times between extreme events have been the central point of statistical analyses in many different areas of science. Simultaneously, the Poincaré recurrence time has…
Stickiness in mushroom billiards
Eduardo G. Altmann, Adilson E. Motter, Holger Kantz
We investigate dynamical properties of chaotic trajectories in mushroom billiards. These billiards present a well-defined simple border between a single regular region and a single…
Stochastic analysis of road surface roughness
M. Waechter, F. Riess, H. Kantz +1
This paper was withdrawn by the authors due to significant new findings. A new paper on the same topic has been submitted as physics/0310159.
The human ECG - nonlinear deterministic versus stochastic aspects
Holger Kantz, Thomas Schreiber
We discuss aspects of randomness and of determinism in electrocardiographic signals. In particular, we take a critical look at attempts to apply methods of nonlinear time series an…
