一個(gè)利用task和電平敏感的always塊設(shè)計(jì)比較后重組信號(hào)的組合邏輯的實(shí)例。可以看到，利用task非常方便地實(shí)現(xiàn)了數(shù)據(jù)之間的交換，如果要用函數(shù)實(shí)現(xiàn)相同的功能是非常復(fù)雜的；另外，task也避免了直接用一般語(yǔ)句來(lái)描述所引起的不易理解和綜合時(shí)產(chǎn)生冗余邏輯等問(wèn)題。

The task of clustering Web sessions is to group Web sessions based on similarity and consists of maximizing the intra- group similarity while minimizing the inter-group similarity． The first and foremost question needed to be considered in clustering W b sessions is how to measure the similarity between Web sessions．However．there are many shortcomings in traditiona1 measurements．This paper introduces a new method for measuring similarities between Web pages that takes into account not only the URL but also the viewing time of the visited web page．Yhen we give a new method to measure the similarity of Web sessions using sequence alignment and the similarity of W eb page access in detail Experiments have proved that our method is valid and e幣cient．

Visual tracking is one of the key components for robots to accomplish a given task in a dynamic environment, especially when independently moving objects are included. This paper proposes an extension of Adaptive Visual Servoing (hereafter, AVS) for unknown moving object tracking. The method utilizes binocular stereo vision, but does not need the knowledge of camera parameters. Only one assumption is that the system need stationary references in the both images by which the system can predict the motion of unknown moving objects. The basic ideas how we extended the AVS method such that it can track unknown moving objects are given and formalized into a new AVS system. The experimental results with proposed control architecture are shown and a discussion is given.
