用一门面向对象语言建立一个针对LL(1)文法分析构造演示器，输入定义好的文法，进行分析后在内存中建立其存储结构，判断其能用LL(1)文法分析后，建立其分析过程。 为此我们将本任务分解为以下内容： （1）文法的建立； （2）上下文无关文法的判定； （3）消除文法中一切左递归的算法； （4）文法二义性的判定； （5）LL(1)文法的判定； （6）消除直接左递归； （7）消除间接左递归； （8）直接左公因子的改造； （9）间接左公因子的改造； （10）递归子程序的构造； （11）根据布尔矩阵求Follow集； （12）能导出ε的非终结符； （13）根据定义构造First集； （14）根据关系图构造First集； （15）根据定义构造Follow集； （16）根据关系图构造Follow集； （17）Select集的构造； （18）预测分析表的构造； （19）总控程序的构造； （20）语法树的演示； （21）根据总控程序输出语法树； （22）根据布尔矩阵求First集。 我所要完成的任务是 语法树的演示。

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．

This is a simple GPS tracer developed for Window Mobile 2005/2003 on Compact Framework 2.0 SDK. So first of all, you need VisualStudio 2005 and Windows Mobile CE 5 SDK. You can develop it on emulator devices or on a real device. As you can see in that photo, I developed that application on a read device: the great Asus MyPal 636N.

Recent advances in experimental methods have resulted in the generation of enormous volumes of data across the life sciences. Hence clustering and classification techniques that were once predominantly the domain of ecologists are now being used more widely. This book provides an overview of these important data analysis methods, from long-established statistical methods to more recent machine learning techniques. It aims to provide a framework that will enable the reader to recognise the assumptions and constraints that are implicit in all such techniques. Important generic issues are discussed first and then the major families of algorithms are described. Throughout the focus is on explanation and understanding and readers are directed to other resources that provide additional mathematical rigour when it is required. Examples taken from across the whole of biology, including bioinformatics, are provided throughout the book to illustrate the key concepts and each technique’s potential.
