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

本文讨论半导体产品特征循环及其对产品技术发展的 启示 。分析指出，半导体产品的主特征一直遵循着“通用” 与“专用”交替发展，每十年波动一次，目前正进入以嵌入 式可编程SoC为特征的专用（可称为专用可编程产品，ASPP波动阶段。同时还指出了牧村浪潮与我们提出的“半导体产品特征循环”的共同点与分歧。根据预测，半导体产品将在ASPP发展中，向用户可重构片上系统（U-SoC, User-reconfigurable SoC）方向发展，进入传统硅微电子技术的最后一次通用波动。文中最后分析了可重构计算的发展现状和存在的问题，以及今后的发展方向。

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.
