Automated Chirp Detection with Diffusion Entropy: Application to Infrasound from Sprites
M. Ignaccolo, T. Farges, E. Blanc +1
We study the performance of three different methods to automatically detect a chirp in background noise. (1) The standard deviation detector uses the computation of the signal to n…

Aging Induced Multifractality
P. Allegrini, J. Bellazzini, G. Bramanti +3
We show that the dynamic approach to Lévy statistics is characterized by aging and multifractality, induced by an ultra-slow transition to anomalous scaling. We argue that these as…

A non-extensive approach to the time evolution of Lyapunov coefficients
Massimiliano Ignaccolo, Paolo Grigolini
We study sporadic randomness by means of a non-extensive form of Lyapunov coefficient. We recover from a different perspective the same conclusion as that of an earlier work, namel…
