We define a projection operator in the framework of the temporal logic programming. Its syntax and semantics are presented and illustrated with examples. We also discuss the implementation details of the projection construct.

This paper introduces a peer-to-peer based network for spam filtering.In this network, CopyRank values of emails are stored and used to determine whether a new email is a spam or not Multi-fingerprints method is proposed and employed to deal with spammer's tricks of slightly changing the content of each copy of a spam.

为了描述集成化软件工程环境用户接口中选单的控制机构,需要引入回溯自动机的概念。本文给出了回溯自动机概念怕严格数学定义,并讨论了它与有穷自动机、确定的下推自动机等之间的关系,证明了它所接受的语言类处于正则语言类与确定的上下文无关语言类之间。

【期刊论文】A Framed Temporal Logic Programming Language
段振华, Zhen-Hua Duan, and Maciej Koutny
May 2004, Vol. 19, No.3, PP. 341~351,-0001,():
-1年11月30日
We discuss the projection temporal logic (PTL), based on a primitive projection operator, prj. A framing technique in also presented, usinig which a synchronization operator, await, is defined withim the underlying logic. A framed temporal logic programming language (FTLL) is presented. To illustrate how to use both the language and framing technique, some examples are given.

【期刊论文】TIMED INTERVAL TEMPORAL LOGIC AND MODELLING OF HYBRID SYSTEMSL
段振华, Z.H. Duan, and W.M. Holcombe, D.A. Linkens
,-0001,():
-1年11月30日
We generalize Interval Temporal Logic to include absolute time and are motivated to model Hybrid systems consisting of discrete, continuous, and heuristic components. The syntax and semantics of Timed Interval Temporal Logic (TITL) are presented, a visual notation, the extended Statecharts with combine TITL, guarded language, and time constraints in a unified manner, is introduced, and an example for the modelling of soaking pits in a steelworks is employed to illustrate how the formalism operates.
