Playfair Cipher 1.not even the large number of keys in a monoalphabetic cipher provides security 2.one approach to improving security was to encrypt multiple letters 3.the Playfair Cipher is an example 4.invented by Charles Wheatstone in 1854,but named after his friend Baron Playfair Playfair Key Matrix 1.a 5X5 matrix of letters based on a keyword 2.fill in letters of keyword (sans duplicates) 3.fill rest of matrix with other letters Encrypting and Decrypting -plaintext is encrypted two letters at a time 1. if a pair is a repeated letter, insert filler like X’ 2. if both letters fall in the same row, replace each with letter to right (wrapping back to start from end) 3. if both letters fall in the same column, replace each with the letter below it (again wrapping to top from bottom) 4. otherwise each letter is replaced by the letter in the same row and in the column of the other letter of the pair

本文討論半導體產(chǎn)品特征循環(huán)及其對產(chǎn)品技術發(fā)展的 啟示 。分析指出，半導體產(chǎn)品的主特征一直遵循著“通用” 與“專用”交替發(fā)展，每十年波動一次，目前正進入以嵌入 式可編程SoC為特征的專用（可稱為專用可編程產(chǎn)品，ASPP波動階段。同時還指出了牧村浪潮與我們提出的“半導體產(chǎn)品特征循環(huán)”的共同點與分歧。根據(jù)預測，半導體產(chǎn)品將在ASPP發(fā)展中，向用戶可重構(gòu)片上系統(tǒng)（U-SoC, User-reconfigurable SoC）方向發(fā)展，進入傳統(tǒng)硅微電子技術的最后一次通用波動。文中最后分析了可重構(gòu)計算的發(fā)展現(xiàn)狀和存在的問題，以及今后的發(fā)展方向。

This is a simple algorithm that downloads trading data from yahoo database. It is basically a large scale application of sqq.m which was originally submitted by Michael Boldin, link at acknowledgements. Some of the functionalities of the package: - User defined ticker list. - Function for downloading most recent SP500 composition in ticker list. - Control for bad data (e.g. a certain percentage of prices missing). - Choice of frequency of data (e.g. weekly prices). - Choice of starting and ending data. - Function for saving the whole data in a pre-formatted excel file together with a full reports on missing data.

The most straightforward approximation is the standard Gaussian approximation, where the MAI is approximated by a Gaussian random variable. This approximation is simple, however it is not accurate in general. In situations where the number of users is not large, the Gaussian approximation is not appropriate. In-depth analysis of must be applied. The Holtzman?s improved Gaussian approximation provides a better approximation to the MAI term. The approximation conditions the interference term on the operation condition of each user.
