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.

用prim算法實驗最小生成樹 本程序中用到函數adjg( ),此函數作用是通過接受輸入的點數和邊數,建立無向圖。函數prg( )用于計算并輸出無向圖的鄰接矩陣。函數prim( )則用PRIM算法來尋找無向圖的最小生成樹 定義了兩個數組lowcost[max],closest[max],若頂點k加入U中,則令lowcost[k]=0。 定義二維數組g[ ][ ]來建立無向圖的鄰接矩陣。

The Inter IC bus or I2C bus is a simple bidirectional two wire bus designed primarily for general control and data transfer communication between ICs. Some of the features of the I2C bus are: • Two signal lines, a serial data line (SDA) and a serial clock line (SCL), and ground are required. A 12V supply line (500mA max.) for powering the peripherals often may be present. • Each device connected to the bus is software addressable by a unique address and simple master/ slave relationships exist at all times masters can operate as master-transmitters or as master-receivers. • The I2C bus is a true multi-master bus including collision detection and arbitration to prevent data corruption if two or more masters simultaneously initiate data transfer systems. • Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 KBit/s in the standard mode or up to 400 KBit/s in the fast mode.

引入PEG(Progressive-edge-growth)算法來構造適合線性時間編碼的LDPC校驗矩陣,譯碼時采用簡化最小和Min-Sum譯碼算法實現簡化譯碼.仿真結果表明,該方法能夠構造適合LDPC碼的線性時間編碼的下三角校驗矩陣日,并且用此方法構造的LDPC碼性能非常接近原來PEG算法構造的LDPC碼.同時通過采用最小和Min-Sum算法降低譯碼復雜度.
