First is that we propose a new method, Hierarchical Segmentation (HS), to analyze non-stationary time series data. The main idea of HS is to divide a series of data into several segments according to the characteristics of data through three level coding. At the upper level, there resemble each other if they have the same codewords. So, it is useful in identifying patterns or special segments with appropriate coding. Here, we apply HS in three different fields: circadian rhythm, moving trajectory and the emotional interaction of couples. In circadian rhythm study, a phase represents each time point for the experiment duration. It is crucial to decide robust and reliable markers as the onset or offset points for the daily activity. We define the onset phase markers via HS; furthermore, we discuss the variation of periods, waveform, and the phase shift inducing by the outside stimulation and develop a new approach in constructing phase response curve (PRC). We compare HS and Onset methods via simulation. It reveals that HS is more robust than Onset; in other words, the phase markers inducing by HS can mark the benchmark in waveform. In the study of oviposition behavior, we explore the moving trajectory of bean weevil and try to find out the moving patterns via HS. We are interested in exploring that if subject changes her moving pattern under three different resource environments. It reveals that the moving patterns is simpler and local search preferred in rich patch than in half and poor. With resource consumed, the moving patterns are increased into lots of long walk. In the couple data analysis, we divide the segments of highly emotional response. After examining with chi-square test, we find that there is coherence situation in both positive and negative emotion. We separate the series data into three segments, and we prove that the approach is helpful in catching the interaction patterns. Finally, we use stochastic small-world network (SSWN) and dynamic movie to represent the dyadic dynamic interactions. The other part is to explore the unstable hierarchy formation in cockroach, Nauphoeta cinerea. We develop two indices to quantify the degree of unstable and the competitive pressure in a group. It reveals that the degree of unstableness is highly related with group size, and there is highly positive relation between unstableness and competitive pressure. In other words, within a group, the more unstable a hierarchy formation is, the stronger the competition appears.Table of Contents Acknowledgments ii Abstract iv List of Tables xi List of Figures xiii
