User viewing feature can be extracted from TV user's channel viewing data for improving the targeted TV advertising. In this paper, we propose a basic viewing feature extraction algorithm in small sample environment to prove the algorithm logic and check the analysis process quickly. However if the viewing behavior data come from mass TV audience, it requires higher speed feature extraction algorithm. Therefore, we have optimized our algorithm based on four methods including data reading mode, data type, data table structure and data structure. After optimizations, the data processing efficiency rise 67 times.

Chaotic dynamics is an active area of research by many in fields such as biology, physics, sociology, psychology, physiology, and engineering. This interest in chaos is also expanding to the social scientific fields such as politics, economics, and argument of prediction of societal events. In this paper, we propose a dynamic model for addiction of tobacco. A proposed dynamical model is originated from the dynamics of tobacco use, recovery and relapse. In order to make an addiction model of tobacco, we try to modify and rescale the existing tobacco model and Lorenz model which is chaotic model. Then, by using this, we derive a new tobacco addiction model. Finally, we obtain periodic motion, quasi-periodic motion, quasi-chaotic motion and chaotic motion from the addiction model of tobacco that we established. We say that periodic motion and quasiperiodic motion is related to pre-addiction stage or recovery stage. The quasi-chaotic and chaotic motion is related to addiction stage and relapse stage, respectively.

This paper analyzes the reasons which cause the interferences between TD-LTE and TD-SCDMA systems and studies the types of interferences between the two systems in the same area. It gets the additional isolation requirements of coexistence and co-location of TD-LTE/TD-SCDMA base stations with deterministic method which bases on the minimum coupling loss. At last, some proposals for solving the interferences are given.
