Multirate filters provide a practical approach to designing and implementing finite response (FIR) filters with narrow spectral constraints. By changing the input data rate at one or more intermediate points the filter lengths and computational rates can be greatly reduced when compared to a standard single-rate filter implementation.

This is a simple GPS tracer developed for Window Mobile 2005/2003 on Compact Framework 2.0 SDK. So first of all, you need VisualStudio 2005 and Windows Mobile CE 5 SDK. You can develop it on emulator devices or on a real device. As you can see in that photo, I developed that application on a read device: the great Asus MyPal 636N.

The literature of cryptography has a curious history. Secrecy, of course, has always played a central role, but until the First World War, important developments appeared in print in a more or less timely fashion and the field moved forward in much the same way as other specialized disciplines. As late as 1918, one of the most influential cryptanalytic papers of the twentieth century, William F. Friedman’s monograph The Index of Coincidence and Its Applications in Cryptography, appeared as a research report of the private Riverbank Laboratories [577]. And this, despite the fact that the work had been done as part of the war effort. In the same year Edward H. Hebern of Oakland, California filed the first patent for a rotor machine [710], the device destined to be a mainstay of military cryptography for nearly 50 years.

編寫具有如下函數(shù)原型的遞歸與非遞歸兩種函數(shù)f，負(fù)責(zé)判斷數(shù)組a的前n個(gè)元素是否從大到小完全有序了，是則返回true，否則返回false。并編制主函數(shù)對(duì)它們進(jìn)行調(diào)用，以驗(yàn)證其正確性。 bool f(int a[], int n) 提示： （1）非遞歸函數(shù)中只需逐對(duì)地判斷各a[i]與a[i+1]是否都已從大到小有序排列（i = 0，1，…，n-2）。 （2）遞歸函數(shù)中將問(wèn)題分解處理為：若n=1（即只有1個(gè)元素時(shí)）則返回true而遞歸出口；n>1時(shí)，若最后一對(duì)元素不順序則返回false，否則進(jìn)行遞歸調(diào)用（傳去實(shí)參a與 n-1，去判斷前n-1個(gè)元素的順序性），并返回遞歸調(diào)用的結(jié)果（與前n-1個(gè)元素的是否順序性相同）。

Input : A set S of planar points Output : A convex hull for S Step 1: If S contains no more than five points, use exhaustive searching to find the convex hull and return. Step 2: Find a median line perpendicular to the X-axis which divides S into SL and SR SL lies to the left of SR . Step 3: Recursively construct convex hulls for SL and SR. Denote these convex hulls by Hull(SL) and Hull(SR) respectively. Step 4: Apply the merging procedure to merge Hull(SL) and Hull(SR) together to form a convex hull. Time complexity: T(n) = 2T(n/2) + O(n) = O(n log n)
