Coupled uncertainty provided by a multifractal random walker
Z. Koohi Lai, S. Vasheghani Farahani, S. M. S. Movahed +1
The aim here is to study the concept of pairing multifractality between time series possessing non-Gaussian distributions. The increasing number of rare events creates "criticality…

Patterns for the waiting time in the context of discrete-time stochastic processes
Tayeb Jamali, G. R. Jafari, S. Vasheghani Farahani
The aim of this study is to extend the scope and applicability of the level-crossing method to discrete-time stochastic processes and generalize it to enable us to study multiple d…

Non-Gaussianity effect of petrophysical quantities by using q-entropy and multi fractal random walk
Z. Koohi lai, S. Vasheghani Farahani, G. R. Jafari
The geological systems such as petroleum reservoirs is investigated by the entropy introduced by Tsallis and multiplicative hierarchical cascade model. When non-Gaussianity appears…
