This report describes flow-control methods for reducing ice problems in rivers. Objectives include reducing ice interference with winter hydroelectric production and navigation, ice jam flood mitigation, as well as ensuring minimum winter flows for fish and water supply. The winter season is divided into three periods. During early winter, the main objective of flow control is to promote the rapid formation of a smooth, stable ice cover. For the midwinter period, the aim of the river regulation is to maintain an intact ice cover and avoid premature ice breakup. During the final winter period, the goal is to minimize adverse effects of ice breakup. Examples illustrate the methods and objectives, emphasizing innovative approaches. Available flow regulation planning tools are described and valuable research directions identified.

You may be sitting there thinking “wow! my life could be better!” or you may be thinking “I’m so jealous I could spit”, or possibly “where is my mocha latte”, but even if you’re thinking “eh, my life is really good too”, in fact especially if you’re thinking that last part, you need to read this book. If you think your life is “good enough”, you need this book to see how much better it could be. If you think your life needs fixing, it probably does. If you think your pajamas are the perfect size for elephants, they probably are. If you can’t remember the last time you saw a rainbow, then this book is exactly what you need. Buy two because you’re probably going to lose one along the way (especially in step 36: “Throwing books at strangers”).

Today, there is a great deal of attention focused on sustainable growth worldwide. The increase in efficiency in the use of energy may even, in this historical moment, bring greater benefit than the use of renewable energies. Electricity appears to be the most sustainable of energies and the most promising hope for a planet capable of growing without compromising its own health and that of its inhabitants. Power electronics and electrical drives are the key technologies that will allow energy savings through the reduction of energy losses in many applications. This Special Issue has collected several scientific contributions related to energy efficiency in electrical equipment. Some articles are dedicated to the use and optimization of permanent magnet motors, which allow obtaining the highest level of efficiency. Most of the contributions describe the energy improvements that can be achieved with power electronics and the use of suitable control techniques. Last but not least, some articles describe interesting solutions for hybrid vehicles, which were created mainly to save energy in the smartest way possible.

Initially, the only electric loads encountered in an automobile were for lighting and the starter motor. Today, demands on performance, safety, emissions, comfort, convenience, entertainment, and communications have seen the working-in of seemingly innumerable advanced electronic devices. Consequently, vehicle electric systems require larger capacities and more complex configurations to deal with these demands. Covering applications in conventional, hybrid-electric, and electric vehicles, the Handbook of Automotive Power Electronics and Motor Drives provides a comprehensive reference for automotive electrical systems. This authoritative handbook features contributions from an outstanding international panel of experts from industry and academia, highlighting existing and emerging technologies. Divided into five parts, the Handbook of Automotive Power Electronics and Motor Drives offers an overview of automotive power systems, discusses semiconductor devices, sensors, and other components, explains different power electronic converters, examines electric machines and associated drives, and details various advanced electrical loads as well as battery technology for automobile applications. As we seek to answer the call for safer, more efficient, and lower-emission vehicles from regulators and consumer insistence on better performance, comfort, and entertainment, the technologies outlined in this book are vital for engineering advanced vehicles that will satisfy these criteria.

Like many a Canadian kid, Stephen Smith was up on skates first thing as a boy, out in the weather chasing a puck and the promise of an NHL career. Back indoors after that didn’t quite work out, he turned to the bookshelf. That’s where, without entirely meaning to, he ended up reading all the hockey books. There was Crunch and Boom Boom, Slashing! and High Stick; there was Max Bentley: Hockey’s Dipsy-Doodle Dandy, Blue Line Murder, and Nagano, a Czech hockey opera. There was Blood on the Ice, Cracked Ice, Fire On Ice, Power On Ice, Cowboy On Ice, and Steel On Ice. In Puckstruck, Smith chronicles his wide-eyed and sometimes wincing wander through hockey’s literature, language, and culture, weighing its excitement and unbridled joy against its costs and vexing brutality. In exploring his own lifelong love of the game, hoping to surprise some sense out of it, he sifts hockey’s narratives in search of hockey’s heart, what it means and why it should distress us even as we celebrate its glories. On a journey to discover what the game might have to say about who we are as Canadians, he seeks to answer some of its essential riddles.

The Power of Purpose begins with a simple but remarkable statement: “The more you focus on helping others, the more you will succeed in reaching your own goals.” Peter S. Temes builds on this fundamental insight to share a simple plan for living with the truest and most enduring kind of happiness. At the heart of The Power of Purpose are the “three levels of thinking.” At the first level, we ask, Who am I? and What do I want? At the second level, we ask, Who do other people think I am? How do I look to them? But the real magic happens when we hit the third level, forgetting about ourselves and asking the questions that lend a powerful sense of purpose to our lives: How do others look to themselves? How can I help others become the people they want to be? To help us along the way, Temes, who teaches humanities at Columbia University, draws on the wisdom of great thinkers including Aristotle, Søren Kierkegaard, and Abraham Lincoln; the life lessons of great achievers ranging from Mother Teresa to Michael Jordan; and home truths he’s gathered from his parents, his grandparents, and his three children. From all these sources and from his own life of great personal accomplishment, Temes identifies the essential knowledge that brings people happiness and success. He cites Aristotle’s notion that happiness is not a psychological state but a moral one, resulting from doing good in the world. Temes also believes in the pivotal importance of trust and team-building in every area of life, from the family to the workplace to the street corner. The Power of Purpose is a map for finding the confidence and power, the opportunities and occasions, and—most important—the techniques and strategies for centering your relationships and work on helping others. It is a book with a point of view: the clearest path to your own success and happiness lies in helping others get to where they want to go.

Only when the power goes off and food spoils do we truly appreciate how much we rely on refrigerators and freezers. In Refrigeration Nation, Jonathan Rees explores the innovative methods and gadgets that Americans have invented to keep perishable food cold—from cutting river and lake ice and shipping it to consumers for use in their iceboxes to the development of electrically powered equipment that ushered in a new age of convenience and health. As much a history of successful business practices as a history of technology, this book illustrates how refrigeration has changed the everyday lives of Americans and why it remains so important today. Beginning with the natural ice industry in 1806, Rees considers a variety of factors that drove the industry, including the point and product of consumption, issues of transportation, and technological advances. Rees also shows that how we obtain and preserve perishable food is related to our changing relationship with the natural world.
