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.

在包 hugeinteger 中創建功能類 HugeInteger，該類用來存放和操作一個不超過 40 位的大整數。 (1) 定義一個構造函數，用來對大整數進行初始化。參數為一個字符串。 (2) 定義 input 成員函數，實現大整數的重新賦值。參數為一個字符串，無返回 值。 (3) 定義 output 成員函數，將大整數輸出到屏幕上。無參數無返回值。 (4) 定義 add 成員函數，實現兩個大整數的加法。參數為一個 HugeInteger 對 象，無返回值，例如： HugeInteger A = new HugeInteger("12345"); HugeInteger B = new HugeInteger("1234"); A.add(B); 此時，A 為 13579，B 為 1234。 (5) 定義 sub 成員函數，實現兩個大整數的減法。參數和返回值同 add 函數。 (6) 定義若干大整數關系運算的成員函數，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，≤）。這些函數的參數為一個 HugeInteger 對象，返回值為一個 布爾類型，表示關系運算的結果，例如： HugeInteger A = new HugeInteger("12345"); HugeInteger B = new HugeInteger("1234"); 那么此時 A.isGreaterThan(B)的結果應當為 True，表示 12345>1234。
