DC electric power distribution systems have higher efficiency, better current carrying capacity and faster response when compared to conventional AC systems. They also provide a more natural interface with many types of renewable energy sources. Furthermore, there are fewer issues with reactive power flow, power quality and frequency regulation, resulting in a notably less complex control system. All these facts lead to increased applications of DC systems in modern power systems. Still, design and operation of these systems imposes a number of specific challenges, mostly related to lack of mature protection technology and operational experience, as well as very early development stage of standards regarding DC based power infrastructure. This book provides an up-to-date overview of recent research activities in the control, protection and architectural design of a number of different types of DC distribution systems and microgrids. Practical requirements and implementation details of several types of DC distribution systems used in the real world industrial applications are also presented. Several types of coordinated control design concepts are shown, with concepts of stabilization being explained in detail. The book reviews the shortcomings and future developments concerning the practical DC system integration issues.

"When Golf was Fun" is a collection of tales from what is known as the "beer and barbecue circuit" of golf tournaments. These tournaments held in small town all across the state of Texas were not only the beginning of the careers of many great golfers but also produced some local legends. It was a time when golf was still a game, not a big business. This collection of 38 stories will entertain and amaze as you read first-hand accounts of some of the greatest exploits in the history of golf. You will read about local golf pros who are unknown outside of their local country club and you will also read about legends like Ben Crenshaw, Bruce Lietzke, Charles Coody, Miller Barber, Ben Hogan and others. Texas has a very rich golf history and much of it is captured in "When Golf was Fun." The late, great beer and barbecue circuit was a bygone era of Texas golf in which many Lone Star legends were born and raised but has since given way to the more civilized and organized golf industry we know today. Much like baseball's barnstorming days, the barbecue circuit was a series of unaffiliated events that brought an extremely high level of golf and excitement to tiny towns like Center and Athens; Quanah and Pampa-places you might otherwise never have known even existed.

The "Continuum Contemporaries" series is designed to be a source of ideas and inspiration for members of book clubs and reading groups, as well as for literature students at school, college and university. The series aims to give readers accessible and informative introductions to 30 of the most popular, most acclaimed and most influential novels of recent years. A team of contemporary fiction scholars from both sides of the Atlantic has been assembled to provide a thorough and readable analysis of each of the novels in question. The books in the series all follow the same structure, which features: a biography of the novelist, including other works, influences and, in some cases, an interview; a full-length study of the novel, drawing out the important themes and ideas; summaries of how the novel was received upon publication and how it has performed since publication, including film or TV adaptations and literary prizes; a wide range of suggestions for further reading, including websites; and a list of questions for reading groups or students to discuss.
