摘要：
The intelligent education software have brought much excitement into the computer-based teaching community, become more important in many mathematics curricula, take the Supper Sketch Pad (SSP) for example, which can help many students to learn new knowledge effectively, to retrieval knowledge easily. Firstly, this paper discusses the knowledge of dynamic geometry, introduces the free version of SSP in Chinese. Secondly, it emphasizes on retrieval new knowledge by geometric invariant, and automatic reasoning using SSP. Finally, it shows applications of the intelligent education software in mathematics teaching.

摘要：
The amount of digitally available information is growing at an exponential rate. Educational resource systems are in widespread use and knowledge develops and spreads rapidly in quality, quantity, profundity and extension. This paper describes a new model of knowledge element to organize knowledge and to share the educational resource, and presents the framework of a knowledge abstract and fusion system based on it.

摘要：
For students, classroom teaching is the process of learning knowledge from teachers. The efficiency of the teaching and learning process is affected by the choice of a teaching tool and the creation of classroom environment to a large extent. In this paper, the design and development of a new teaching system - soft whiteboard system is introduced in details, which provide more support for the teachers to create a positive and interactive classroom environment, thus to improve the teaching and learning efficiency.

摘要：
80% of learning in organizations takes place informally outside of the formal classroom and e-learning courses, as indicated by the studies. Web2.0 software and technologies play an important role in supporting informal learning. There will be few technological troublesome if you choose a platform or framework provided by others. On the basis of introducing two forms of informal learning: personal learning environment and communities of practice, this paper explores strategies of implementing web2.0 informal learning, Finally, an example of communities of practice is present to illustrate how we can make use of it to support informal learning.

摘要：
In WSNs, energy efficiency and low latency are considered as two key issues in designing routing protocol. This paper proposes a two layer hierarchical routing protocol called chain routing based on coordinates-oriented clustering strategy (CRBCC), which gives a good compromise between energy consumption and delay. First, CRBCC makes balanced clustering according to y coordinates where each cluster has approximately equal number of nodes. Second, CRBCC makes chain routing by simulated annealing algorithm (SA) inside the cluster and elects chain leader in the order of x coordinates. Third, CRBCC makes chain routing again by SA method among chain leaders. Simulation results show that CRBCC performs better than PEGASIS in terms of energy efficiency and network delay.
摘要：
P2P traffic has become one of the most significant portions of the network traffic. How to improve the accuracy of the traffic identification efficiently is still a difficult problem. A promising approach that has recently received some attention is traffic classification using machine learning techniques. In this paper, we propose a BP neural network algorithm for P2P traffic classification problem. We implement a P2P traffic identification prototype system which can realize offline learning and online classification of P2P traffic effectively. The results show that the method provides a promising way to measure aggregate P2P traffic.
摘要：
This paper discusses the synchronization of uncertain control, a novel active pining control strategy is chaotic systems. The proposed controller can achieve synchronization between a salve system and a master system, and ensure the synchronized robust stability of make chaotic systems achieve synchronization in a quite short period and the synchronization is of good robust stability.
