Security Benefits of Cloud Computing

Abstract: Today, we can easily notice how the nature of the internet is changing from a place used to read web pages to an environment that allows the users to run software applications.Nowadays, with the development of web page ,the newest web page has up to web

pages 3.0,also called the intelligent web ,which is the next stage of the internet evolution. the cloud means the internet .the term is derived from the way in which the internet is often represented into the network diagrams .the current cloud computing architecture involves the existence of the data centers that are able to provide services to the clients located al overthe world. the main advantages of the cloud computing are the following :there is no need to download or install a specific software and update the local system, users or clients don’t afraid to the computing crashing, because everything is stored into cloud .the cost is low or even free ,like mobile phone or PDAs. the cloud computing can be used .but everything has its short leg ,there are some disadvantages as well, like :it is hard to integrate with the existing in-house infrastructure .there are not enough major suppliers in this field and so on.Some major Security benefits for individuals or companies, like the following: centralizing data storage ,increasing uncertainty, virtualization allows a rapid replacement of

在控制系统中，若给定的输入信号是预先未知且随时间变化的，并且系统的输出量随输入量的变化而变化，这种系统就称为随动系统。快速跟踪和准确定位是随动系统的两个重要技术指标。传统的伺服控制系统通常采用模拟随动系统，即用运算放大器及外围电阻、电容元件实现比例、微分、积分校正网络，来改善系统的动态及静态特性。实际工作中我们感到模拟伺服随动系统具有算法呆板，电路调试繁琐，系统响应慢等诸多不足。随着计算机技术、现代控制理论的迅猛发展，由数字控制装置组成的随动系统即数字随动系统应运而生。

数字随动系统 是输出量以一定精度复现输入量变化的自动控制系统, 它在对生产过程和运动对象的控制中, 以及在定位、瞄准、跟踪等装置中都占有显著的地位, 现己成为各种自动调节系统的组成部分。

本文的研究对象是数字随动系统,并结合数字随动系统的原理设计一个比较简单的数字随动系统实验装置。

关键字：快速跟踪 准确定位 伺服控制系统 数字控制装置 数字随动系统

Abstract

In the control system, if the input signal is given in advance of the unknown and change over time, and change due to the change in output with the input, this kind of system is called a servo system.Is fast tracking and accurate positioning servo system of two important technical indicators.Servo control systems are often used for traditional analog servo system, using operational amplifiers and peripheral resistance, capacitance components to achieve scale, differential, integral calibration network, to improve the system of dynamic and static characteristics.In the actual work we are simulating algorithm of servo system with rigid, circuit debugging cumbersome and inadequate systems respond slowly and many other.With the rapid development of computer technology, modern control theory, by numeric control servo system of the digital servo system came into being.

（基于Text 1 How Do Computer Hackers “Get Inside” a Computer?）

Abstract

Computer vulnerabilities are often utilized by hackers or crackers. The security of each computer is challenging. This paper firstly redefines the term “hacker”, “cracker” and “getting inside” the computers and describes the procedure in detail. The term “unauthorized user” (UU) will be a better choice for defining the insider group. The known and unknown vulnerabilities will be taken advantage of by UUs ranging from poor password protection to leaving a computer turned on and physically accessible to visitors in the office. The first step of employing technical exploits will be the determination of the specifications of the target system. There are two ways of attacking including being through capabilities inherent in hypertext transfer protocol (http) and being preprogrammed against specific vulnerabilities and launched without any specific target. The variability of hacking action including the weak system and the strong system warns the users to choose the right way to protect the computer and do not authorize the computer to others easily. Lastly, the solution of avoiding vulnerabilities has been given, including updating patches, making complex passwords, getting information only from the reliable websites or services, updating anti-virus software and backing up the data to protect the computer not being hacked.

Native American Influences on Modern U.S. Culture

When the first Europeans came to the North American continent, they encountered the completely new cultures of the Native American. Peoples of North America, Native Americans, who had highly developed cultures in many respects, must have been as curious about them. As always happens when two or more cultures come into contact, there was a cultural exchange. Native Americans adopted some of the Europeans’ ways, and the Europeans adopted some of their ways. As a result, Native Americans have made many valuable contributions to modern U.S. culture, particularly in the areas of language, art, food, and government.
