Figure 2: (a) DFA of the original series. For each order-n DFA there exists two crossovers s1x(n) and s2x(n) (We usesx(n) for them) which divide the curves into 3 different scaling segments whose scaling exponents are: α0(n), α1(n) and α2(n) respectively (We use α(n) for them). (b) The DFA of a sinusoidal series given by the function 10*sin(20πi/N), where N is the length of the original series
