This book has been written to support a practically oriented course in programming language translation for senior undergraduates in Computer Science. More specifically, it is aimed at students who are probably quite competent in the art of imperative programming (for example, in C++, Pascal, or Modula-2), but whose mathematics may be a little weak students who require only a solid introduction to the subject, so as to provide them with insight into areas of language design and implementation, rather than a deluge of theory which they will probably never use again students who will enjoy fairly extensive case studies of translators for the sorts of languages with which they are most familiar students who need to be made aware of compiler writing tools, and to come to appreciate and know how to use them. It will hopefully also appeal to a certain class of hobbyist who wishes to know more about how translators work.

MySQL is the world’s most popular open source database, sporting a barrier of entry low enough to attract novice developers yet powerful enough to power some of the world’s most popular websites, among them Yahoo!, BBC News, the U.S. Census Bureau, and Craigslist. This reference card was created to help you quickly navigate some of MySQL’s most popular features. Covering topics such as confguration, administration software, backup procedures, SQL features, and user management, this card will serve as a handy desk reference for countless projects to come.

The software and hardware development fields evolved along separate paths through the end of the 20th century. We seem to have come full circle, however. The previously rigid hardware on which our programs run is softening in many ways. Embedded systems are largely responsible for this softening. These hidden computing systems drive the electronic products around us, including consumer products like digital cameras and personal digital assistants, office automation equipment like copy machines and printers, medical devices like heart monitors and ventilators, and automotive electronics like cruise controls and antilock brakes. Embedded systems force designers to work under incredibly tight time-tomarket, power consumption, size, performance, flexibility, and cost constraints. Many technologies introduced over the past two decades have sought to help satisfy these constraints. To understand these technologies, it is important to first distinguish the underlying embedded systems elements.

电动汽车用异步电机系统效率优化控制研究 (中科院博士论文)目前,大量应用于工农业生产的交流异步电机驱动系统,存在着整体效率较低的缺陷,造成资源浪费严重。本文以应用于电动汽车的中小功率等级异步电机驱动系统为研究对象,并针对被广泛应用的SVPWM电压型逆变器输出调制电压中含有基波电压以及谐波电压的实际特点,提出要从两个方面对稳态轻载工况下异步电机系统进行效率优化控制:优化电机的基波励磁磁链,寻找由基波电压所引起的电机铁芯损耗和铜损的最优平衡点,以减少由基波电压引起的电机损耗 优化SVPWM发生方法,控制逆变器的谐波电压输出,以减少由谐波电压引起的电机铁芯损耗和铜损。论文主要包括以下几个方面: 针对常用MATLAB/Simulink模块库所提供的异步电机模型不包含铁芯损耗这一缺陷,本文提出了一种计及铁芯损耗的异步电机数学模型,模型不包含微分环节,保证了仿真时的稳定性,模型所需参数均可通过普通的短路和空载实验获取。模型符合电机实际情况,具有简单、可靠、易于实现的优点。 基于损耗模型控制(LMC)以及最小直流母线功率在线搜索控制(SC)的研究成果,本文提出了一种新型混合在线式直流最小功率模糊搜索效率优化控制算法(FLSC)。

Computing and the way people use C for doing it keeps changing as years go by. So overwhelming has been the response to all the previous editions of “Let Us C” that I have now decided that each year I would come up with a new edition of it so that I can keep the readers abreast with the way C is being used at that point in time.

It’s your first day in the lab.Undoubtedly you are experiencing a range of emotions: excitement, curiosity, anxiety. You will be working in this lab and with a group of people, as well as with your supervisor, for several years to come. This is the first day of a long commitment and, for some, a hard road ahead. Which is why it’s important to get off on the right foot.

According to the Oxford English Dictionary, the first known historical meaning of the word information in English was the act of informing, or giving form or shape to the mind, as in education, instruction, or training. A quote from 1387: "Five books come down from heaven for information of mankind."
