一、 进程控制 1、 定义PCB（可以采用静态结构或动态结构）：包括理论PCB中的基本内容，如ID、进程状态、队列指针。由于无法实现真正的进程创建功能，在实验中只需建立PCB，用它代表完整的进程。 2、 定义进程状态转换方式：进程的状态转换是由进程内部操作或操作系统的控制引起，由于无法实现这些功能，学生可以采用随机数方法或键盘控制方法模拟，并实现对应的控制程序。随机方法指产生1－6的随机数，分别代表创建进程(c)、结束进程(e)、进程阻塞(b)、激活进程(w)、调度进程(p)、时间片到(t)等事件；键盘模拟方法指定义6种按键代表以上6种事件。 3、 根据四种事件处理就绪队列、阻塞队列和当前执行中的进程。 每次事件处理后应形象地显示出当前系统中的执行进程是哪一个，就绪队列和阻塞队列分别包含哪些进程。

The AVRcam source files were built using the WinAVR distribution (version 3.3.1 of GCC). I haven t tested other versions of GCC, but they should compile without too much difficulty. * The source files for the AVRcam had the author name and copyright information added back into them after the judging of the project, since it states in the competition rules that the author s name can not be present during their inspection. * The included source files are the ones that were submitted for the entry into the Circuit Cellar contest. I have continued to develop the AVRcam, and have added several new features (such as ignoring objects that aren t larger than a minimum size, removing tracked objects that overlap with each, and some general optimizations). If you are interested in the latest source, email me at john@jrobot.net * For more info about the AVRcam, check out http://www.jrobot.net John Orlando August 20, 2004

一个基于GTK+的单词数值计算器，1、 按照规则计算单词的值，如果 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 26个字母（全部用大写）的值分别为 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26，如： WINJACK这个单词的值就为：W+I+N+J+A+C+K=23+9+14+1+3+11=71％ HARDWORK=H+A+R+D+W+O+R+D=8+1+18+4+23+15+18+11=98％ LOVE=L+O+V+E=12+15+22+5=54％ LUCK=L+U+C+K=12+21+3+11=47％ ATTITUDE= A+T+T+I+T+U+D+E=1+20+20+9+20+24+4+5=100％ 2、对程序的界面布局参考如下图所示，在第一个单行文本框输入一个单词，点击“计算”按钮，按照以上算法计算出该单词的值。 3、如果在最下面的单行文本框输入一个文件路径，此文件每行记录一个单词，那么经过程序计算出各个单词的值，并把结果输出到当前目录下result.txt文件中。如果文件不存在，应该提示错误。

This document provides guidelines and describes how to easily port S60 2nd Edition C++ applications to S60 3rd Edition. The document has been written based on experiences of porting regular S60 2nd Edition applications, such as the S60 Platform: POP/IMAP Example [4] that can be downloaded from Forum Nokia. Code snippets from the example are shown in Chapter 8, “Application build changes,” and in Appendix A, “Code example." In addition, Appendix B, "Commonly used functions that require capabilities," and Appendix C, "Commonly used interfaces that have been changed or removed," provide useful information on some frequently used functions and interfaces in third-party applications.

tensor 向量的推广。在一个坐标系下，由若干个数（称为分量）来表示，而在不同坐标系下的分量之间应满足一定的变换规则，如矩阵、多变量线性形式等。一些物理量如弹性体的应力、应变以及运动物体的能量动量等都需用张量来表示。在微分几何的发展中，C.F.高斯、B.黎曼、E.B.克里斯托费尔等人在19世纪就导入了张量的概念，随后由G.里奇及其学生T.列维齐维塔发展成张量分析，A.爱因斯坦在其广义相对论中广泛地利用了张量。

c语言编程宝典,C 语言是1972年由美国的Dennis Ritchie设计发明的, 并首次在UNIX操作系统 的 DEC PDP-11 计算机上使用。 它由早期的编程语言 BCPL( Basic Combind Programming Language) 发展演变而来。在1970年, AT&T 贝尔实验室的 Ken Thompson根据BCPL语言设计出较先进的并取名为 B的语言, 最后导了C 语言的问世。 随着微型计算机的日益普及, 出现了许多C 语言版本。由于没有统一的标准, 使得这些C 语言之间出现了一些不一致的地方。为了改变这种情况, 美国国家标准 研究所(ANSI)为C 语言制定了一套ANSI标准, 成为现行的C语言标准。
