Analyzing Chaos Systems and Fine Spectrum Sensing Using Detrended Fluctuation Analysis Algorithm

Figure 7

The DFA of the variable (Lorenz system) at different parameter values; in (a) the dashed line and the dotted line correspond to the DFA curves when the parameters and are varied, respectively; in (b), (c), and (d) the dotted line corresponds to the parameter , the dashed line with circles corresponds to the parameter , and the dashed line with diamonds corresponds to the parameter . The average over the DFA graphs when all Lorenz parameters are varied is presented in (b). The standard deviation as a function of the scale and the parameters value range are presented in (c) and (d), respectively.
