回文判别 实验要求：称正读和反读都相同的字符序列为“回文”，如“abba”和“abccba”是“回文”，“abcde”和“ababab”则不是“回文”，试设计一个算法，判别读入的一个以@为结束符的字符序列是否是“回文”。 实验目的： 1、掌握循环队列的定义及应用； 2、掌握队列的基本操作； 3、进一步熟练掌握栈的基本操作及应用； 4、初步学会解决具体问题的算法设计。-Experimental identification requirements palindrome: that is read and the anti-time sequence of characters are the same as a " palindrome" , such as " abba" and " abccba" is " palindrome" , " abcde" and " ababab" is not " palindrome" and try to design an algorithm to determine a time to @ for the character sequence at the end of it is " Palindrome." The experiment was: 1, master cycle and application of the definition of the queue 2, master the basic operation of the queue 3, and further stack master the basic operation and applications 4, a preliminary settlement of specific issues of the Institute of algorithm design.

近年来小波包变换的比较好的文献，非常有价值(The relatively good literature of wavelet packet transformation in recent years is of great value)

C# Treeview树控导航菜单示例，虽然是一个简单的树形菜单实例，不过如果你想实现此类菜单的话，这个例子绝对是很具参考性，因为里面演示了如何创建节点、如何实现分隔符，如何设置图像集合，如何设置不能编辑，如何显示连线，如何显示“+”号和“—”号等，另外还有增加子节点和主节点的方法等，下一步这个示例会结合数据库，实现动态的树形展开菜单。

金融中优化模型的讲义，对数学建模很有用，希望大家多多下载-Optimization model finance lectures on mathematical modeling is useful, I hope everyone a lot of downloads

VB 基于API HOOK拦截程序源码，演示VB如何拦截API呼叫，這是網友問的問題,雖然這個問題並不適合用VB做,但並不是做不到,要多繞一段路,這個問題重點在於執行檔中的IAT(Import Address Table) 如果你對於PE黨並不熟悉 請參考PE檔簡介。一個Process再執行時,會將許多DLL載入到行程空間中,如呼叫User32.dll中的MessageBoxW就必須將User32.dll載入到位址空間,呼叫越多不同種的API,位址空間中的模組也就越多,至於如何得知行程所載入的模組請參考如何取得Process中載入的模組的資訊。 　　一般來說,如果是執行Notepad.exe 我們只要攔截模組Notepad.exe的IAT即可,除非你想攔截Notepad.exe是否有透過其他DLL去執行要攔截的函數,才需要去攔截其他載入的模組，這個程式整個攔截的過程如下： 　　1.在要攔截的程式上配置2塊記憶體空間,一塊用來放要攔截的程式,一塊用來放所需要用的區域變數 至於如何再外部程式配置記憶體請參考如何在外部程式配置記憶體 　　AddressOfRemoteFunction=CreateRemoteMememory(SomeProcess,FunctionSize) 　　AddressOfVar=CreateRemoteMememory(SomeProcess,DataSize) 　　2.將要注射的函數寫到配置的位址空間 並初使化變數 　　Call WriteCodeTo(AddressOfRemoteFunction) 　　[AddressOfVar]=1 　　[AddressOfVar+256]=Old_FunctionAddress 　　3.修改IAT位址到新配置的函數

In many areas of commerce, government, academia, and hospitals, large collections of digital images are being created. Many of these collections are the product of digitizing existing collections of analogue photographs, diagrams, drawings, paintings, and prints. Usually, the only way of searching these collections was by keyword indexing, or simply by browsing. Digital images databases however, open the way to content-based searching. In this paper we survey some technical aspects of current content-based image retrieval systems.
