| Abstract: | The C-C method was adopted to analyze the nonlinear characteristics of masseter electromyography (EMG) signals and the chaotic degree by the largest Lyapunov exponent (LLE) of different genders and sides.First,the embedding dimension and the delay time were obtained through this method,then the phase space was reconstructed to resume the chaotic attractor and determine the LLE.The result shows that the trajectory of attractor is denser than Chen's attractor,and the LLE is positive,which means that not only ... |
