## Ergodic Estimations of Upscaled Coefficients for Diffusion in Random Velocity Fields

AbstractUpscaled coefficients for diffusion in ergodic velocity fields are derived by summing up correlations of increments of the position process,…

## Multiscale structure of time series revealed by the monotony spectrum

AbstractObservation of complex systems produces time series with specific dynamics at different time scales. The majority of the existing numerical…
