Statistical analysis of wind speed fluctuation and increments of non-stationary atmospheric boundary layer turbulence
T. Laubrich, F. Ghasemi, J. Peinke +1
We study the statistics of the horizontal component of atmospheric boundary layer wind speed. Motivated by its non-stationarity, we investigate which parameters remain constant or…
Uncertainty in the Fluctuations of the Price of Stocks
G. R. Jafari, M. Sadegh Movahed, P. Noroozzadeh +4
We report on a study of the Tehran Price Index (TEPIX) from 2001 to 2006 as an emerging market that has been affected by several political crises during the recent years, and analy…
Analysis of Non-stationary Data for Heart-Rate Fluctuations in Terms of Drift and Diffusion Coefficients
F. Ghasemi, Muhammad Sahimi, J. Peinke +1
We describe a method for analyzing the stochasticity in the non-stationary data for the beat-to-beat fluctuations in the heart rates of healthy subjects, as well as those with cong…
Long range correlation in cosmic microwave background radiation
M. Sadegh Movahed, F. Ghasemi, Sohrab Rahvar +1
We investigate the statistical anisotropy and Gaussianity of temperature fluctuations of Cosmic Microwave Background radiation (CMB) data from {\it Wilkinson Microwave Anisotropy P…
Statistical Properties of the Interbeat Interval Cascade in Human Subjects
Fatemeh Ghasemi, J. Peinke, M. Reza Rahimi Tabar +1
Statistical properties of interbeat intervals cascade are evaluated by considering the joint probability distribution for two interbeat increments and…
Dynamics of the Markov Time Scale of Seismic Activity May Provide a Short-Term Alert for Earthquakes
M. Reza Rahimi Tabar, Muhammad Sahimi, K. Kaviani +9
We propose a novel method for analyzing precursory seismic data before an earthquake that treats them as a Markov process and distinguishes the background noise from real fluctuati…
