Signal analysis and hysteresis modeling of meridian systems

Meridian system is one of the very important issues for disease diagnosis and treatment in traditional Chinese medicine. Recently, people have found out that the meridian systems in human body are complex nonlinear and dynamic systems. This paper focuses on the analysis of signals measured form meridian systems. It finds out that the energy values on the meridian points are quite different from those on the non-meridian points. Moreover, the hysteretic phenomenon has been found in the meridian systems. In order to describe the hysteretic behavior of human meridian systems, the modeling procedure based on neural networks is presented. Then, the experimental results of the hysteresis modeling are illustrated.
