The light time series was analyzed by applying detrended fluctuation analysis to estimate the long-range power-law correlation exponents α. The scaling exponent was calculated for all systems and its value indicated a signature of each kind of system, i.e., whether flare takes place (with α=1.22) or not (with α=0.64). As a consequence, our results may identify the stability of the systems from the scaling exponent α value, for instance, if α∼0.5 (white noise) the system is stable and unstable when α≠0.5 (long-range power-law correlation).Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2013-12-11T11:26:44Z No. of bitstreams: 1 E.
