Exploitation of memory effects in complex systems (Einjähriges Forschungsstipendium an der Boston University, Boston/USA)

Bewilligung: 11.10.2005 Laufzeit: 1 Jahr

Observables of complex systems show more or less pronounced memory effects. This can be rigorously derived within the Mori-Zwanzig theory. Recently the group developed an algorithm to quantitatively characterize memory effects by analyzing one time series of such an observable. During a one-year research stay with Prof. H. E. Stanley, University of Boston, it is planned to improve the algorithm and to exploit memory effects. In order to use memory effects in forecasting and control applications the probability distribution of the non-Markovian residual forces needs to be estimated from experimental data and compared with analytical approaches. In this project the probability distribution shall be determined with the aid of stochastic integration and optimization methods.
