Book Description
"Rojek's argument is a psychological one, although his message is political: global events build on people's needs to feel empowered and jointly engaged in the pursuit of a higher purpose; they allow a break from daily routines, provide an illusion of intimacy and social membership, and create a sense of self-validation and personal gratification. In short, participation in such events makes us feel good. At the same time, the real effect of global events seems to be the maintenance of global inequality and social injustice, as well as huge profits for the organizations involved in planning, commercializing and securing these happenings. In sketching out this palliative function of global events from the perspective of people's needs on the one hand, and unveiling their puppet masters backstage on the other, Rojek's book presents a compelling account of the role of organized events in modern society." - Organization Studies Events dominate our screens, our lives, and increasingly global geopolitics. Analysis of events and their management has remained rooted in leisure and management studies - until now. This break-through book provides an introduction to event management, while also situating events in questions of power and social control. Rojek powerfully argues that events are essential elements in corporate-state partnerships of 'invisible government' that have revived the romance of charity as to form illusory communities, while cloaking power imbalances and social inequalities. Events are moving politics from the old idea of 'the personal is political' to the new, more seductive notion that 'representation is resistance'. Wielding rich case studies from the World Cup and the Olympics to Live Aid, Burning Man and Mardi Gras, Rojek presents a dazzlingly original account of communication power, social ordering and control. It is essential reading in media & communication studies and across the social sciences.

Book Description
This introductory text covers basic electronics and the behavior of passive components, circuit analysis and systematic troubleshooting. The analytical methods used are strongly based on Ohm's and Kirchoff's Laws. Mathematics are used for analysis, but only after a solid, intuitive understanding of circuit or device operation has been established. With a heavy emphasis on critical thinking over rote memorization, and the coverage of state of the art technology, this text truly prepares students to use and apply the knowledge they acquire.

Book Description
This book is the third in a series of four devoted to POWER ELECTRONIC CONVERTERS: The first of these concerns AC to DC conversion. The second concerns AC to AC conversion. This volume examines DC to DC conversion. The fourth is devoted to DC to AC conversion. Converters which carry out the DC-DC conversion operate by chopping the input voltage or current: they are called choppers or switch-mode power converters. Their operating frequency is not imposed by either the input or the output, both of which are at zero frequency. A frequency which is much greater than that of the industrial network can be chosen, provided that suitable configurations and semiconductor devices are used. This is the first difference compared to the rectifiers and AC-AC converters, analyzed in the previous volumes and which often operate at the industrial network frequency. The second difference concerns the commutation mode. Choppers operate in forced commutation. The beginning of an operating phase does not auto matically turn off the semiconductor devices which were conducting during the previous phase and which have to be brought to the blocking state. This turn-off must be carried out autonomously. These two differences - the higher frequency of commutations and, espe cially, the different mode of commutation -justify the first two chapters in this work: - Chapter 1 examines general notions concerning converters, supplies and loads, and more especially, how they can be characterized with regard to commutations.

Book Description
DC-DC converters have many applications in the modern world. They provide the required power to the communication backbones, they are used in digital devices like laptops and cell phones, and they have widespread applications in electric cars, to just name a few. DC-DC converters require negative feedback to provide a suitable output voltage or current for the load. Obtaining a stable output voltage or current in presence of disturbances such as: input voltage changes and/or output load changes seems impossible without some form of control. This book tries to train the art of controller design for DC-DC converters. Chapter 1 introduces the DC-DC converters briefly. It is assumed that the reader has the basic knowledge of DC-DC converter (i.e., a basic course in power electronics). The reader learns the disadvantages of open loop control in Chapter 2. Simulation of DC-DC converters with the aid of Simulink® is discussed in this chapter as well. Extracting the dynamic models of DC-DC converters is studied in Chapter 3. We show how MATLAB® and a software named KUCA can be used to do the cumbersome and error-prone process of modeling automatically. Obtaining the transfer functions using PSIM® is studied as well. These days, softwares are an integral part of engineering sciences. Control engineering is not an exception by any means. Keeping this in mind, we design the controllers using MATLAB® in Chapter 4. Finally, references are provided at the end of each chapter to suggest more information for an interested reader. The intended audiencies for this book are practice engineers and academians.

Book Description
Understanding DC Circuits covers the first half of a basic electronic circuits theory course, integrating theory and laboratory practice into a single text. Several key features in each unit make this an excellent teaching tool: objectives, key terms, self-tests, lab experiments, and a unit exam. Understanding DC Circuits is designed with the electronics beginner and student in mind. The authors use a practical approach, exposing the reader to the systems that are built with DC circuits, making it easy for beginners to master even complex concepts in electronics while gradually building their knowledge base of both theory and applications. Each chapter includes easy-to-read text accompanied by clear and concise graphics fully explaining each concept before moving onto the next. The authors have provided section quizzes and chapter tests so the readers can monitor their progress and review any sections before moving onto the next chapter. Each chapter also includes several electronics experiments, allowing the reader to build small circuits and low-cost projects for the added bonus of hands-on experience in DC electronics. Understanding DC Circuits fully covers dozens of topics including energy and matter; static electricity; electrical current; conductors; insulators; voltage; resistance; schematic diagrams and symbols; wiring diagrams; block diagrams; batteries; tools and equipment; test and measurement; series circuits; parallel circuits; magnetism; electromagnetism; inductance; capacitance; soldering techniques; circuit troubleshooting; basic electrical safety; plus much more.
