程序用JAVA語言編寫, 綜合利用圖結構和堆棧結構進行數據組織和處理. 可以進行正則表達式到NFA的轉化, 并能用圖形直觀的表示. 對正則表達式有一些約定, 就是可以用單個字符表示輸入, 也可以用 ‘ ‘ 連接起來的一串字符進行輸入. 有基本的表達式以及由基本表達式構成的并置, 選擇和重復的操作. 例: A|b*c ‘LETTER’*’digit’ 等都是合法輸入. 還帶有括號功能, 優先級

The JICQ is the bureau area which JAVA writes according to "Customer s Machine/Server"(C/S) mode message solid hour correspond by LETTER tool system, the system adopted the SQL Server2000 of Microsoft company as a backstage database, the system passes a JDBC interview database. The system is divided into the server procedure and customer s procedure two parts, server and customer adoption "Transmission Control Protocol"(TCP), connect a word (Socket) conjunction through a set, the adoption "User Datagram Protocol "(UDP) of the customer s, pass a data report a set to connect a word (DatagramSocket) establishment a conjunction. The system has customer registration, customer to register, increase good friend, delete good friend and send out and receive news etc. function.

Problem Statement You are given a string input. You are to find the longest substring of input such that the reversal of the substring is also a substring of input. In case of a tie, return the string that occurs earliest in input. Definition Class: ReverseSubstring Method: findReversed Parameters: string Returns: string Method signature: string findReversed(string input) (be sure your method is public) Notes The substring and its reversal may overlap partially or completely. The entire original string is itself a valid substring (see example 4). Constraints input will contain between 1 and 50 characters, inclusive. Each character of input will be an uppercase LETTER ( A - Z ). Examples 0) "XBCDEFYWFEDCBZ" Returns: "BCDEF" We see that the reverse of BCDEF is FEDCB, which appears later in the string. 1)

We address the problem of blind carrier frequency-offset (CFO) estimation in quadrature amplitude modulation, phase-shift keying, and pulse amplitude modulation communications systems.We study the performance of a standard CFO estimate, which consists of first raising the received signal to the Mth power, where M is an integer depending on the type and size of the symbol constellation, and then applying the nonlinear least squares (NLLS) estimation approach. At low signal-to noise ratio (SNR), the NLLS method fails to provide an accurate CFO estimate because of the presence of outliers. In this LETTER, we derive an approximate closed-form expression for the outlier probability. This enables us to predict the mean-square error (MSE) on CFO estimation for all SNR values. For a given SNR, the new results also give insight into the minimum number of samples required in the CFO estimation procedure, in order to ensure that the MSE on estimation is not significantly affected by the outliers.

Noncoherent receivers are attractive for pulsed UWB systems due to the implementation simplicity. To alleviate the noise effect in detecting UWB PPM signals, this LETTER proposes a simple yet flexible weighted noncoherent receiver structure, which adopts a square-law integrator multiplied with a window function.

北京大學ACM比賽題目 Write a program to read four lines of upper case (i.e., all CAPITAL LETTERS) text input (no more than 72 characters per line) from the input file and print a vertical histogram that shows how many times each LETTER (but not blanks, digits, or punctuation) appears in the all-upper-case input. Format your output exactly as shown.
