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])

利用“原始套接字”(Raw Socket),我们可访问位于基层的传输协议。本章专门讲解如 何运用这种原始套接字,来模拟I P的一些实用工具,比如Tr a c e r o u t e和P i n g程序等等。使用原 始套接字,亦可对I P头信息进行实际的操作。本章只关心I P协议;至于如何针对其他协议使 用原始套接字,我们不打算提及。而且,大多数协议(除AT M以外)根本就不支持原始套接 字。所有原始套接字都是使用S O C K _ R AW这个套接字类型来创建的,而且目前只有Wi n s o c k 2提供了对它的支持。因此,无论Microsoft Windows CE 还是老版本的Windows 95 (无 Winsock 2升级)均不能利用原始套接字的能力。

This section contains a brief introduction to the C language. It is intended as a tutorial on the language, and aims at getting a reader new to C started as quickly as possible. It is certainly not intended as a substitute for any of the numerous textbooks on C. 2. write a recursive function FIB (n) to find out the nth element in theFibanocci sequence number which is 1,1,2,3,5,8,13,21,34,55,…3. write the prefix and postfix form of the following infix expressiona + b – c / d + e * f – g * h / i ^ j4. write a function to count the number of nodes in a binary tr

问题描述:编写一个JAVA程序,用面向对象设计的方法编写一个电话卡的类。包括卡号、密码、余额、拨入号码等 b)基本要求:类的属性有卡号、密码、余额、拨入号码,电话卡的常用操作可以用连接电话方法、返回余额方法与通电话方法来实现。 c)方法功能描述: 构造方法(PhoneCard(卡号,密码,余额,拨入号码))可以完成属性值初始化赋值,并判断余额,余额为负就退出系统,请在构造方法中将初始时的连接置为false即表示没有连接。 卡号long cardNumber 密码private int password,余额double balance,拨入号码string connectNumber boolean connected(一个布尔类型变量表示电话卡连接状态,初始时默认没有连接,值为false,当调用连接电话方法()后,在判断卡号和密码相匹配后值置为true) 连接电话方法(performConnection(卡号,密码))可以完成检查卡号和密码,它是只有在卡号和密码相匹配时才连接 返回余额方法(getBalance())得到电话卡的余额 通电话方法(performDial())是模拟通过过程中,余额会不断减少,每调用此方法,电话卡的余额减少0。5元,打一次电话调用一次
