數(shù)字運(yùn)算，判斷一個(gè)數(shù)是否接近素?cái)?shù) A Niven number is a number such that the sum of its digits divides itself. For example, 111 is a Niven number because the sum of its digits is 3, which divides 111. We can also specify a number in another base b, and a number in base b is a Niven number if the sum of its digits divides its value. Given b (2 <= b <= 10) and a number in base b, determine whether it is a Niven number or not. Input Each line of input contains the base b, followed by a string of digits representing a positive integer in that base. There are no leading zeroes. The input is terminated by a line consisting of 0 alone. Output For each case, print "yes" on a line if the given number is a Niven number, and "no" otherwise. Sample Input 10 111 2 110 10 123 6 1000 8 2314 0 Sample Output yes yes no yes no

The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A characters. The first character in the decree specifies whether a must come ( B )Before b in the new alphabet or ( A )After b . The second character determines the relative placement of b and c , etc. So, for example, "BAA" means that a must come Before b , b must come After c , and c must come After d . Any letters beyond these requirements are to be excluded, so if the decree specifies k comparisons then the new alphabet will contain the first k+1 lowercase letters of the current alphabet. Create a class Alphabet that contains the method choices that takes the decree as input and returns the number of possible new alphabets that conform to the decree. If more than 1,000,000,000 are possible, return -1. Definition

There is an example of how to use the LDPC encode/decode with AWGN channel model in files .\ldpc_decode.m and .\GFq\ldpc_decode.m. There are a few parity check matrices available in the code but you can use other matrices provided you have enough memory to load them. I suggest checking out matrices in Alist format available on David MacKay s web site.You will need to have access to a MEX compiler to be able to use a few functions written in C. LDPC的仿真代碼

TLV1544與TMS320VC5402通過串行口連接，此時(shí)，A／D轉(zhuǎn)換芯片作為從設(shè)備，DSP提供幀同步和輸入／輸出時(shí)鐘信號。TLV1544與DSP之間數(shù)據(jù)交換的時(shí)序圖如圖3所示。 開始時(shí)， 為高電平（芯片處于非激活狀態(tài)），DATA IN和I/OCLK無效，DATAOUT處于高阻狀態(tài)。當(dāng)串行接口使CS變低（激活），芯片開始工作，I／OCLK和DATAIN能使DATA OUT不再處于高阻狀態(tài)。DSP通過I／OCLK引腳提供輸入／輸出時(shí)鐘8序列，當(dāng)由DSP提供的幀同步脈沖到來后，芯片從DATA IN接收4 b通道選擇地址，同時(shí)從DATAOUT送出的前一次轉(zhuǎn)換的結(jié)果，由DSP串行接收。I／OCLK接收DSP送出的輸入序列長度為10～16個(gè)時(shí)鐘周期。前4個(gè)有效時(shí)鐘周期，將從DATAIN輸入的4 b輸入數(shù)據(jù)裝載到輸入數(shù)據(jù)寄存器，選擇所需的模擬通道。接下來的6個(gè)時(shí)鐘周期提供模擬輸入采樣的控制時(shí)間。模擬輸入的采樣在前10個(gè)I／O時(shí)鐘序列后停止。第10個(gè)時(shí)鐘沿（確切的I／O時(shí)鐘邊緣，即上升沿或下降沿，取決于操作的模式選擇）將EOC變低，轉(zhuǎn)換開始。

OpenSVM was developped under Visual C++ 6.0 SP6, You can open the workspace file(*.dsw) in the opensvm-src folder. The folder include the svm.h and svm.cpp which in the libsvm (Copyright (c) 2000-2007 Chih-Chung Chang and Chih-Jen Lin All rights reserved) in the opensvm-src\libsvm. However, the files svm.h and svm.cpp codes were copied/merged into stdafx.h and stdafx.cpp in order to support the development, and OpenSVM still use other codes of libsvm. So you can see the libsvm package in the source package. You can open and build it with Visual C++ 6.0. Note: the problems must be in LIBSVM format. OpenSVM project page: http://sourceforge.net/projects/opensvm If you had any question, please mail to: cloudbyron@gmail.com

The XML Toolbox converts MATLAB data types (such as double, char, struct, complex, sparse, logical) of any level of nesting to XML format and vice versa. For example, >> project.name = MyProject >> project.id = 1234 >> project.param.a = 3.1415 >> project.param.b = 42 becomes with str=xml_format(project, off ) "<project> <name>MyProject</name> <id>1234</id> <param> <a>3.1415</a> <b>42</b> </param> </project>" On the other hand, if an XML string XStr is given, this can be converted easily to a MATLAB data type or structure V with the command V=xml_parse(XStr).

The task of clustering Web sessions is to group Web sessions based on similarity and consists of maximizing the intra- group similarity while minimizing the inter-group similarity． The first and foremost question needed to be considered in clustering W b sessions is how to measure the similarity between Web sessions．However．there are many shortcomings in traditiona1 measurements．This paper introduces a new method for measuring similarities between Web pages that takes into account not only the URL but also the viewing time of the visited web page．Yhen we give a new method to measure the similarity of Web sessions using sequence alignment and the similarity of W eb page access in detail Experiments have proved that our method is valid and e幣cient．
