The Swiss Federal Office of Topography is leading a project for the determination of correct agricultural surfaces. As a part of this project, a Digital Terrain Model and a Digital Surface Model is being generated using airborne laser scanning methods. These two models must achieve a height accuracy of 50cm and a mean density of 1 point per m. One of the… (More)

The strange sets which arise in deterministic low-dimensional dynamical systems are analysed in terms of (unstable) cycles and their eigenvalues. The general formalism of cycle expansions is introduced and its convergence discussed. PACS numbers: 0320,0545

We compute the decay of the autocorrelation function of the observable |vx| in the Sinai billiard and of the observable vx in the associated Lorentz gas with an approximation due to Baladi, Eckmann and Ruelle. We consider the standard configuration where the disks is centered inside a unit square. The asymptotic decay is found to be C(t) ∼ c(R)/t. An… (More)

We consider a deterministic realization of Parrondo games, and use periodic orbit theory to analyze their asymptotic behavior.

In the framework of quantum chaos, the theory of dynamical localization plays an outstanding role, both for its conceptual relevance and physical import. Theoretical arguments, confirmed by a large amount of numerical simulations, have shown in the case of complete classical chaos, that the localization length is related to the classical diffusion constant… (More)

We investigate the dependence of Poincaré recurrence-time statistics on the choice of recurrence set by sampling the dynamics of two- and four-dimensional Hamiltonian maps. We derive a method that allows us to visualize the direct relation between the shape of a recurrence set and the values of its return probability distribution in arbitrary phase-space… (More)

In Pires et al. [Phys. Rev. E 84, 066210 (2011)], intermittent maps were considered, and the tight relationship between correlation decay of smooth observables and large deviation estimates as, for instance, employed in Artuso and Manchein [Phys. Rev. E 80, 036210 (2009)], was questioned. We try to clarify the problem and to provide rigorous arguments and… (More)
