Power law spectra and intermittent fluctuations due to uncorrelated Lorentzian pulses
O. E. Garcia, A. Theodorsen
A stochastic model for intermittent fluctuations due to a super-position of uncorrelated Lorentzian pulses is presented. For constant pulse duration, this is shown to result in an…
Statistical properties of a filtered Poisson process with additive random noise: Distributions, correlations and moment estimation
Audun Theodorsen, Odd Erik Garcia, Martin Rypdal
Filtered Poisson processes are often used as reference models for intermittent fluc- tuations in physical systems. Such a process is here extended by adding a noise term, either as…
Amplitude and size scaling for interchange motions of plasma filaments
R. Kube, M. Wiesenberger, O. E. Garcia
The interchange dynamics and velocity scaling of blob-like plasma filaments are investigated using a two-field reduced fluid model. For incompressible flows due to buoyancy the max…
Level crossings, excess times and transient plasma-wall interactions in fusion plasmas
Audun Theodorsen, Odd Erik Garcia
Based on a stochastic model for intermittent fluctuations in the boundary region of magnetically confined plasmas, an expression for the level crossing rate is derived from the joi…
Scrape-off layer turbulence in TCV: evidence in support of stochastic modelling
A. Theodorsen, O. E. Garcia, J. Horacek +2
Intermittent fluctuations in the TCV scrape-off layer have been investigated by analysing long Langmuir probe data time series under stationary conditions, allowing calculation of…
