Rotating shafts experience a an elliptical motion called whirl. It is important to decompose this motion into a forward and backward whil orbits. The current function makes use of two sensors to generate a bi-directional spectrogram. The method can be extended to any time-frequency distribution ％ ％ compute the forward/backward Campbell/specgtrogram ％ ％ INPUT: ％ y (n x 2) each column is measured from a different sensor ％ /////// ％ __ ％ |s1| y(:,1) ％ |__| ％ __ ％ / \ ________|/ ％ | | | s2 |/ y(:,2) ％ \____/ --------|/ ％ ％ Fs Sampling frequnecy ％ ％ OUTPUT: ％ B spectrogram/Campbel diagram ％ x x-axis coordinate vector (time or Speed) ％ y y-axis coordinate vector (frequency [Hz])

Implemented BFS, DFS and A* To compile this project, use the following command: g++ -o search main.cpp Then you can run it: ./search The input is loaded from a input file in.txt Here is the format of the input file: The first line of the input file shoud contain two chars indicate the source and destination city for breadth first and depth first algorithm. The second line of input file shoud be an integer m indicate the number of connections for the map. Following m lines describe the map, each line represents to one connection in this form: dist city1 city2, which means there is a connection between city1 and city2 with the distance dist. The following input are for A* The following line contains two chars indicate the source and destination city for A* algorithm. Then there is an integer h indicate the number of heuristic. The following h lines is in the form: city dist which means the straight-line distance from the city to B is dist.

RS232.C was written to provide all of the basic functionality needed to employ serial I/O in any application written with Borland C language compilers. Some features are: 1. Ease of use. No assembly language or library files are used and a simple "#include" statement is all that is required to access all of the functions provided. 2. Both input and output are buffered and interrupt driven for efficiency. 3. Serial ports 1 - 4 are supported on PC, AT and PS/2 compatibles.Chained interrupts used on port 3 and 4 are allowed for so as not to interfere with devices such as a mouse or printer. Transmission speeds of 110 to 115200 baud are available. 4. Detection and utilization of hardware buffered UARTs (NS16550AF etc.) found in some machines is automatic. 5. Interrupt driven hardware and XON/XOFF flow control is provided for. 6. All source code is included. RS232.C can be used with all memory models.

正整数x 的约数是能整除x 的正整数。正整数x 的约数个数记为div(x)。例如，1，2，5，10 都是正整数10 的约数，且div(10)=4。设a 和b 是2 个正整数，a≤b，找出a 和b之间约数个数最多的数x。 对于给定的2 个正整数a≤b，编程计算a 和b 之间约数个数最多的数。 数据输入 输入数据由文件名为input.txt的文本文件提供。文件的第1 行有2 个正整数a和b。 结果输出 程序运行结束时，若找到的a 和b 之间约数个数最多的数是x，将div(x)输出到文件output.txt中。 输入文件示例 输出文件示例 input.txt output.txt 1 36 9

在包 hugeinteger 中创建功能类 HugeInteger，该类用来存放和操作一个不超过 40 位的大整数。 (1) 定义一个构造函数，用来对大整数进行初始化。参数为一个字符串。 (2) 定义 input 成员函数，实现大整数的重新赋值。参数为一个字符串，无返回 值。 (3) 定义 output 成员函数，将大整数输出到屏幕上。无参数无返回值。 (4) 定义 add 成员函数，实现两个大整数的加法。参数为一个 HugeInteger 对 象，无返回值，例如： HugeInteger A = new HugeInteger("12345"); HugeInteger B = new HugeInteger("1234"); A.add(B); 此时，A 为 13579，B 为 1234。 (5) 定义 sub 成员函数，实现两个大整数的减法。参数和返回值同 add 函数。 (6) 定义若干大整数关系运算的成员函数，包括 isEqualTo（等于，=）、 isNotEqualTo（不等于，≠）、isGreaterThan（大于，>）、isLessThan（小 于，<）、isGreaterThanOrEqualTo（大于等于，≥）和 isLessThanOrEqualTo （小于等于，≤）。这些函数的参数为一个 HugeInteger 对象，返回值为一个 布尔类型，表示关系运算的结果，例如： HugeInteger A = new HugeInteger("12345"); HugeInteger B = new HugeInteger("1234"); 那么此时 A.isGreaterThan(B)的结果应当为 True，表示 12345>1234。
