Long-range correlations with finite-size effects from a superposition of uncorrelated pulses with power-law distributed durations
M. A. Korzeniowska, O. E. Garcia
Long-range correlations manifested as power spectral density scaling for frequency and a range of exponents are investigated for a superposition of uncorrelated p…
Time delay velocity estimation from a superposition of localized and uncorrelated pulses
J. M. Losada, O. E. Garcia
This study investigates a novel method for estimating two-dimensional velocities using coarse-grained imaging data, which is particularly relevant for applications in plasma diagno…
Blob velocities and sizes in the Alcator C-Mod scrape-off layer for ohmic and high confinement mode plasmas
A. D. Helgeland, J. M. Losada, J. L. Terry +1
An improved time delay estimation method is used to calculate the velocity of cross-field blob motion in the scrape-off layer of Alcator C-Mod for an ohmic and two high confinement…
Stochastic modeling of blob-like plasma filaments in the scrape-off layer: Time-dependent velocities and pulse stagnation
O. Paikina, J. M. Losada, A. Theodorsen +1
A stochastic model for a super-position of uncorrelated pulses with a random distribution of and correlations between amplitudes and velocities is analyzed. The pulses are assumed…
