Third, it has a discussion on the development of modern and traditional artificial neural network technology and their application in image processing. It summaries that the model of the Pulse-coupled neural network based on Elkhorn's model of the cat visual cortex was constructed according to the mammalian vision systems. The nonlinear modulation property, which is a generic and pervasive biological pulse-coupling mechanism, is used in the construction of PCNN. So, PCNN finds many applications in image processing, including segmentation, edge extraction et al. As all known, the performance of the image segmentation depends not only directly on the adjustment of PCNN parameters and the statistical properties of image but also on the cyclic iteration times N of PCNN. If the parameters have been properly set, it turns out to be essential to select a suitable criterion to determine N.

回顾了神经网络技术的现状，指出传统人工神经网络只利用了生物神经元有限的属性进行模型构建，而90年代产生的脉冲耦合神经网络充分利用了哺乳动物视神经网络特有属性，其神经元模型除了考虑生物神经元特有的线性相加、兴奋与抑制属性外，还考虑到生物神经元特有的非线性相乘调制耦合特性；考虑了哺乳动物视神经系统视野受到适当刺激时，相邻连接神经元同步激发产生35Hz～70Hz振荡脉冲串特性等，所以PCNN网络模型更靠近真实生物视觉特性，特别是哺乳动物视神经网络，特别适合计算机图像处理应用，尤其在生物细胞图像分割、图像平滑、降噪及图像中目标的分类、计数等方面的研究。

An automatic update system based on semantic web techniques to implement the drug-law checking automatically is proposed in this thesis. The design concept is to use OWL as the knowledge model. To represent the drug law knowledge, we view a drug law as a class of medical status, and we can use classification to implement the decision of drug use legality. This approach simplifies the design of inference engine. The OWL supports the syntax of class inherences, so it can reach the cognitive economy and shorten the drug laws encoding length. The OWL syntax can represent most drug laws style, so the system can just use one document and one inference engine to handle all drug laws rules.

本文导入语意网技术提出一法规检核同步化系统，来实现药品检核规则自动更新的功能，其主要设计理念为以语意网的OWL模型来实作法规检核系统，在法规的知识表徵上，系统将所有的药品规则视为医疗状态的类别，因此判别用药的合法性，便可使用分类运算达成，这简化了推理机的设计；利用OWL支援类别继承的语意，故能形成认知经济性效应，缩小医疗法规机器编码长度；最后OWL的语法能表示大部份规则型态，使得系统可以使用一个文件档，一种推理机模型便能表示所有的法规。

In this paper, we have conducted some experiments on the ISCAS89 benchmarks that are in form of EDIF. We compare FEAS algorithm, FEAS plus algorithm and algorithm based on classify paths on running time. Those algorithms are implemented in C language. At last we conclude that our algorithms can achieve retiming transforming quickly.
