Local statistical moments to capture Kramers-Moyal coefficients
Christian Wiedemann, Matthias Wächter, Jan A. Freund +1
This study introduces an innovative local statistical moment approach for estimating Kramers-Moyal coefficients, effectively bridging the gap between nonparametric and parametric m…
Assessing the Suitability of the Langevin Equation for Analyzing Measured Data Through Downsampling
Pyei Phyo Lin, Matthias Wächter, Joachim Peinke +1
The measured time series from complex systems are renowned for their intricate stochastic behavior, characterized by random fluctuations stemming from external influences and nonli…
Dynamics of wind turbine operational states
Henrik M. Bette, Christian Wiedemann, Matthias Wächter +3
Modern wind turbines gather a wealth of data with Supervisory Control And Data Acquisition (SCADA) systems. We study the short-term mutual dependencies of a variety of observables…
Capturing rogue waves by multi-point statistics
Ali Hadjihosseini, Matthias Wächter, Norbert P. Hoffmann +1
As an example for complex systems with extreme events we investigate ocean wave states exhibiting rogue waves. We present a statistical method of data analysis based on multi-point…
Extracting strong measurement noise from stochastic series: applications to empirical data
Pedro G. Lind, Maria Haase, Frank Böttcher +3
It is a big challenge in the analysis of experimental data to disentangle the unavoidable measurement noise from the intrinsic dynamical noise. Here we present a general operationa…
Small and Large Scale Fluctuations in Atmospheric Wind Speeds
F. Böttcher, St. Barth, J. Peinke
Atmospheric wind speeds and their fluctuations at different locations (onshore and offshore) are examined. One of the most striking features is the marked intermittency of probabil…
