Description: 申请一个10M的文件空间虚拟成一个磁盘，按照1K大小划分扇区，依序编号，实现单卷单级目录的文件系统。
根据文件分配方案设计相应的FCB结构，空闲空间管理结构，磁盘卷总信息结构，目录区信息结构等，存放在虚拟磁盘的相应区域
编写管理程序，实现对虚拟磁盘的全权控制，犹如针对真实磁盘使用模式类似DOS或者Linux的终端方式
本文简单介绍了磁盘文件格式FAT及其他相关背景和算法,并采用FAT方案实现单卷、单级目录的虚拟文件系统。描述了整个程序的基本思路模块划分、流程图及代码的实现。-application of a 10M file space into a virtual disk, according to the size of 1K division sector, in order numbers, to achieve a single volume directory single file system. According to the paper distribution program to design appropriate FCB structure, and the leisure space management structure, the total disk volumes of information structure, District information directory structure, stored in the virtual disk preparation of the corresponding regional management procedures, to achieve the virtual disk full control as with real disk usage patterns similar to the DOS or Linux terminal is a simple way of Disk File FAT format, and other relevant background and algorithms, and using FAT programs to achieve a single volume. single-level directory of virtual file system.

Description: 现有的几个网络拓扑随机发生器，其实很难生成理想的网络拓扑结构，其主要原因在于很难控制节点的疏密和间距。我们提出来的这个改进算法，在随机抛撒节点的时候使用了K均值聚类，由本算法作为网络拓扑发生器，网络节点分布均匀且疏密得当，边的分布也比较均衡-The few existing random network topology generator, is in fact very difficult to generate the desired network topology, the main reason it is difficult to control the node density and spacing. We put forward the improved algorithm, throw in random nodes when using the K-means clustering, by the algorithm as a network topology generator, network nodes and spacing evenly distributed properly, the edge of a more balanced distribution of

Description: 一个报童从报刊发行中心订报后零售，每卖一份报纸可赚钱a元；若报纸卖不出去，则退回发行处，每退一份要赔钱b元。每天报童卖出的份数是随机的，但报童可以根据以往卖报情况统计得到每天卖k份报纸的概率密度p(k)。
（1） 求报童每天期望收益达到最大（或损失达到最小）的定报量z。
（2） 改变参数a/b的值，观察订报量的最优值变化，画出变化曲线。
试画出仿真流程图，进行程序实现，并对仿真结果进行分析。

Newsboy sold shares in a day is random, but the newsboy can sell based on past statistics reported to be selling daily newspaper k the probability density p (k). (1) seeking newsboy expected profit per day to maximize (or minimize loss) reported that the volume of fixed-z. (2) change the parameters a/b values, subscribe to observe changes in the volume of the optimal value, draw curve.

Description: ) Compression using huffman code
-with a number of bits k per code word
-provide huffman table
Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code table for encoding a source symbol. The table is derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol .Huffman coding uses a specific method for representing each symbol, resulting in a prefix code that expresses the most common characters using shorter strings of bits than those used for less common source symbols.The Huffman coding is a procedure to generate a binary code tree.
