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币cient.

用prim算法实验最小生成树 本程序中用到函数adjg( ),此函数作用是通过接受输入的点数和边数,建立无向图。函数prg( )用于计算并输出无向图的邻接矩阵。函数prim( )则用PRIM算法来寻找无向图的最小生成树 定义了两个数组lowcost[max],closest[max],若顶点k加入U中,则令lowcost[k]=0。 定义二维数组g[ ][ ]来建立无向图的邻接矩阵。

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)算法来构造适合线性时间编码的LDPC校验矩阵,译码时采用简化最小和Min-Sum译码算法实现简化译码.仿真结果表明,该方法能够构造适合LDPC码的线性时间编码的下三角校验矩阵日,并且用此方法构造的LDPC码性能非常接近原来PEG算法构造的LDPC码.同时通过采用最小和Min-Sum算法降低译码复杂度.
