Microblogging is one of the most popular on-line social services by which people can share information and communicate with others. In the paper, it is proved that in a microblogging's social network, there exists small-world, scale-free and high clustering coefficient characteristics, which are three main properties of complex network. It means that microblogging's social network is a complex network. Besides, it is verified that the number of microblogs and the frequency of posting microblogs follow power-law distributions, which is an evidence that shows human dynamics are non-Poissonian. The related geographical property analysis of microblogging's social network illustrates the reason of users' geographical distribution.

This paper proposes a genetic-based algorithm for surface reconstruction of three-dimension (3-D) objects from a group of contours representing its section plane lines. The algorithm can optimize the triangulation of the surface of 3-D objects with a multi-objective optimization function to meet the needs of a wide range of applications. Further, a new crossover operator for triangulation and a new 3-D quadrilateral mutation operator are also introduced.
