软件设计/软件工程 所有的设计模式都有一些常用的特性：一个标识（a name）
所有的设计模式都有一些常用的特性：一个标识（a name），一个问题陈述（a problem statement）和一个解决方案(a solution)。
1、一个设计模式的标识是重要的，因为它会让其他的程序员不用进行太深入的学习就能立刻理解你的代码的目的（至少通过这个标识程序员会很熟悉这个模式）。?
2、问题描述是用来说明这个模式的应 ...
加密解密 RSA ( Rivest Shamir Adleman )is crypthograph system that used to give a secret information and digit
RSA ( Rivest Shamir Adleman )is crypthograph system that used to give a secret information and digital signature . Its security based on Integer Factorization Problem (IFP). RSA uses an asymetric key. RSA was created by Rivest, Shamir, and Adleman in 1977. Every user have a pair of key, public key a ...

Resource allocation is an important issue in wireless communication networks. In
recent decades, cognitive radio technology and cognitive radio-based networks have
obtained more and more attention and have been well studied to improve spectrum
utilization and to overcomethe problem of spectrum scarc ...
技术资料 基于STC89C52单片机控制的家庭无功功率智能补偿装置
针对家庭电路中感性负载需从电网中吸收大量的无功功率而引起电能损耗的问题,设计了一种新型的家庭无功功率智能补偿装置。以阻感负载电路和功率三角形模型为基础,建立了补偿容量的计算表达式。基于RN8209计量芯片和STC89C52单片机为核心,能准确地进行采样和计算,自动进行电容的投切补偿并实时显示补偿效果。利用Proteus、Mul ...
电源技术 电源供应器与数字电位器校准应用笔记
Abstract: A resistive feedback network is often used to set the output voltage of a power supply. A mechanical potentiometer (pot)conveniently solves the problem of adjusting a power supply. For easier automatic calibration, a mechanical pot can be replaced witha digital pot. This application note ...

We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparis ...
