Distributed animation rendering systems are used to speed up of rendering i.e the computational-intensive phase of producing animation. How to develop softwares with high availability and efficiency is a hot topic in distributed animation rendering systems. In this paper, based on model checking method for system modeling, three modules(i.e. rendering management server, rendering nodes and storage system) are modeled and analyzed. Firstly, by analyzing the system's typical infrastructure, messages-driven finite state machines of such three modules are studied. Then, the properties of such three modules are described using CTL(Computational Tree Logic). Furthermore, safety and livenesses are verified with SMV(Symbolic Model Verification). The methodology of this paper offers important theoretical guide to software development.

Mobility pattern of users is decided by people themselves. However, in the daily life, mobile users often repeat regular routes in certain periods. To effectively mine the mobile rules of users and allocate the resource among mobile telecommunication operators and Internet service Providers（ISP）, grasping the models of human mobility can enable effective network planning and advertisement recommending. In this paper, we employ Apriori algorithm method to mine mobile users’ movement model. The algorithm proposed is based on mining the mobility patterns of users, forming mobility rules from these patterns, and finally predicting a mobile user’s next movement by using the mobility rules. The user mobility patterns are mined from the history of mobile user trajectories. In addition to the analysis of individual mobile behavior, it is possible to mine population movement regularity from a large number of user mobile patterns. By studying the group characteristics the place that a large number of users accessed can be found. Operators can optimize the setting of the base station according to the density of users to meet the needs of mobile users.

Over these past 6 years, Hadoop has become a highly popular solution to store and process a large amount of data for analysis purpose. Those 6 years of utilization along with the researches undergone which focused on Hadoop enable researches to have a good overview of its advantages, drawbacks and limitations in order to improve the solution initiated introduced. Even though Hadoop 2.0 released in 2012 brought several improvements, especially regarding Hadoop Distributed File system (HDFS) availability and the cluster resource management during MapReduce job execution through the YARN architecture, numerous scopes of improvements are yet to be explored. This paper aims to present those drawbacks and limitations of Hadoop 1.0, explain what brings Hadoop 2.0 and what these remaining scopes of improvements for Hadoop are.

In order to study the impact of waves on the ship attitude motion and facilitate the ship attitude motion control system design, a ship attitude control platform had been designed to simulate the ship attitude motion on the sea in the laboratory conditions. There is a brief introduction to the basic working principles and basic control flow of the platform from the control platform hardware components and each module features. Based on the Froude-Krylov Hypothesis and regarded the ship as a box, the disturbing moment of regular wave acting on ship with mathematical model can be established. Controlled by two Industrial PCs of the platform, the ship attitude motion has been simulated that effected by regular wave. Contrasting the results of MATLAB simulation with mathematical model and that of the platform movement, it shows that the simulation of wave based on the platform is satisfaction.
