Making Non-English Majors "on the Move"

Researches have proved that adults can develop language acquisition device, too. Transferring from learning to acquisition depends on the interplay of external and internal factors both from the instructor and the students. This paper describes the attempt to help students develop from language learning to language acquisition, from the points of pre-class, while-class, and after-class activities.

A Novel Immune System Model and Its Application to Network Intrusion Detection

Based on analyzing the techniques and architecture of existing network Intrusion Detection System (IDS), and probing into the fundament of Immune System (IS), a novel immune model is presented and applied to network IDS, which is helpful to design an effective IDS. Besides, this paper suggests a scheme to represent the self profile of network. And an automated self profile extraction algorithm is provided to extract self profile from packets. The experimental results prove validity of the scheme and algorithm, which is the foundation of the immune model.
