E-learning learning management systems have appeared for a few of years, but most of them just put their emphasis on ldquolearning contentsrdquo, and ignore supporting and tracking the process of learning. LAM is a new type of learning activity management system which makes a teacher be able to organize various activities of instruction under the support of technology. Itpsilas easy to revise activities...
Nowadays people in the area of e-learning contents development are paying attention to educational computer games, which utilize games in education for pleasant learning. In many respects, the relevant technologies are sufficiently sophisticated for ambitious game designs. However, design theory itself is lagging behind. This study purposes to analyze the status of current educational computer games,...
Assessment is an essential part of classroom teaching, and it plays an important role in teaching. But the traditional assessment is mostly charged by teachers, and there are many shortages. With the development of information technology, it is more efficient to improve teaching by using network technology, especially to assess classroom teaching.

In recent years, the network attack become more and more widespread and difficult in against. The traditional technique, such as Firewall is good, but when malicious traffic originates from inside network or enters through a hole in the firewall you may need another line of defense to protect you. This is a article introducing the concepts of IDS, what they do, the functions they serve, the classification...
Network security has been a very important issue, since the rising evolution of the Internet. There has been an increasing need for security systems against the external attacks from the hackers. One important type is the intrusion detection system (IDS). There are two major categories of the analysis techniques of IDS: the anomaly detection and the misuse detection. Here we forcus on misuse detection,...
In this paper, we present a bandwidth degradation QoS scheme for adaptive multimedia services in next generation wireless/mobile networks, and introduce it in mobile networks to improve the performance of channel allocation. The proposed schemes are the generic call admission control (CAC) algorithm and the admission policy to support multiple rates, multiple class traffic of next generation mobile...
