Draak is a multi-language, macro compiler, meaning all syntax and code generation is defined in a single file. Draak is a single binary that is able to compile any context free language (like C, Pascal, Java) for any platform with only 1 file.
Draak Compiler是一個(gè)多語(yǔ)言，宏編譯器，可以在一個(gè)單獨(dú)的文件中定義所有的語(yǔ)法和代碼生成。Draak 是一個(gè)單獨(dú)的二進(jìn)制文件，可以在任意平臺(tái)上只使用一個(gè)文件來(lái)編譯任何上下文無(wú)關(guān)的語(yǔ)言（類(lèi)似 C, Pascal, Java）。

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.

TLV1544與TMS320VC5402通過(guò)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(hào)。TLV1544與DSP之間數(shù)據(jù)交換的時(shí)序圖如圖3所示。
開(kāi)始時(shí)， 為高電平（芯片處于非激活狀態(tài)），DATA IN和I/OCLK無(wú)效，DATAOUT處于高阻狀態(tài)。當(dāng)串行接口使CS變低（激活），芯片開(kāi)始工作，I／OCLK和DATAIN能使DATA OUT不再處于高阻狀態(tài)。DSP通過(guò)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(lái)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(zhǎng)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(lái)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(kāi)始。

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．

This document provides guidelines and describes how to easily port S60 2nd Edition
C++ applications to S60 3rd Edition. The document has been written based on
experiences of porting regular S60 2nd Edition applications, such as the S60 Platform:
POP/IMAP Example [4] that can be downloaded from Forum Nokia. Code snippets from
the example are shown in Chapter 8, “Application build changes,” and in Appendix A,
“Code example." In addition, Appendix B, "Commonly used functions that require
capabilities," and Appendix C, "Commonly used interfaces that have been changed or
removed," provide useful information on some frequently used functions and interfaces
in third-party applications.

We analyze, both analytically and numerically, the effectiveness
of cloaking an infinite cylinder from observations by electromagnetic
waves in three dimensions. We show that, as truncated approximations
of the ideal permittivity and permeability tensors tend towards
the singular ideal cloaking fields, so that the anisotropy ratio tends to
infinity, the D and B fields blow up near the cloaking surface. Since
the metamaterials used to implement cloaking are based on effective
medium theory, the resulting large variation in D and B will pose a
challenge to the suitability of the field averaged characterization of "
and 碌. We also consider cloaking with and without the SHS (softand-
hard surface) lining, shown in [6] to be theoretically necessary
for cloaking in the cylindrical geometry. We demonstrate numerically
that cloaking is significantly improved by the SHS lining, with both
the far field of the scattered wave significantly reduced and the blow
up of D and B prevented.

Electrostatic discharge (ESD) phenomena have been known to mankind since Thales of
Miletus in approximately 600 B.C.E. noticed the attraction of strands of hay to amber.
Two thousand six hundred years have passed and the quest to obtain a better under-
standing of electrostatics and ESD phenomenon continues. Today, the manufacturing
of microelectronics has continued the interest in the field of electrostatic phenomenon
spanning factory issues, tooling, materials, and the microelectronic industry
