The many variants of the Unix operating system require use of a mode of thought that s significantly different from the one that s required by simpler operating systems. Think Unix introduces readers to important fundamental and intermediate Unix commands and, in the process, inculcates them in the Unix way of thinking. It s a worthy goal in a world with more Linux users than ever, and author Jon Lasser accomplishes it. He s both a capable writer and a knowledgeable user of Unix shell commands. Lasser uses bash under Red Hat Linux in most examples--which usually apply equally well to other Unix variants--and makes asides about other shells and environments, as needed.

在項目中的數據庫層中的數據庫訪問類都從DatabaseObject類派生，這樣只需要在一個地方設置數據連接，其他地方都不需要涉及數據庫訪問的具體連接代碼。 如：User類專門負責Users組的權限控制等，只需要簡單的代碼就可以連接并訪問數據庫了。這里具體實 現與此文章無關，只舉一兩個模塊做例子。

Aodv for NS-2. A mobile ad-hoc network (MANET) is a kind of wireless ad-hoc network, and is a self-configuring network of mobile routers connected wirelessly. MANET may operate in a standalone fashion, or may be connected to the larger Internet. Many routing protocols have been developed for MANETs over the past few years. This project evaluated three specific MANET routing protocols which are Ad-hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Dynamic MANET Ondemand routing protocol (DYMO) to better understand the major characteristics of these routing protocols. Different performance aspects were investigated in this project including packet delivery ratio, routing overhead, throughput and average end-to-end delay.

In the next generation of wireless communication systems, there will be a need for the rapid deployment of independent mobile users. Significant examples include establishing survivable, efficient, dynamic communication for emergency operations, disaster relief efforts, and military networks. Such network scenarios cannot rely on centralized and organized connectivity, and can be conceived as applications of mobile ad hoc networks. A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the network topology may change rapidly and unpredictably over time. The network is decentralized, where all network activity including discovering the

語法分析 C2.1 實驗目的 編制一個遞歸下降分析程序,實現對詞法分析程序所提供的單詞序列的語法檢查和結構分析. C2.2 實驗要求 利用C語言編制遞歸下降分析程序,并對簡單語言進行語法分析. C2.2.1待分析的簡單語言的語法 用擴充的BNF表示如下: (1)<程序>：：＝begin<語句串>end (2)<語句串>：：＝<語句>{ <語句>} (3)<語句>：：＝<賦值語句> (4)<賦值語句>：：＝ID：＝<表達式> (5)<表達式>：：＝<項>｛＋<項> | —項>｝ (6)<項>：：＝<因子>{*<因子> | /<因子>} (7)<因子>：：＝ID | NUM | (<表達式>) Ｃ２。２。２實驗要求說明 輸入單詞串，以“＃”結束，如果是文法正確的句子，則輸出成功信息，打印“success”,否則輸出“error”.

實驗目的 通過上機實習,加深對語法制導翻譯原理的理解,掌握將語法分析所識別的語法成分變換為中間代碼的語義翻譯方法. 實驗要求 采用遞歸下降語法制導翻譯法,對算術表達式、賦值語句進行語義分析并生成四元式序列。 實驗的輸入和輸出 輸入是語法分析提供的正確的單詞串，輸出為三地址指令形式的四元式序列。 例如：對于語句串 begin a:=2+3*4 x:=(a+b)/c end# 輸出的三地址指令如下： （1） t1=3*4 （2） t2=2+t1 （3） a=t2 （4） t3=a+b （5） t4=t3/c （6） x=t4
