Soft-switching PWM full-bridge converters have been widely used in medium-to-high power dc-dc conversions for topological simplicity, easy control and high efficiency. Early works on soft-switching PWM full-bridge converter by many researchers included various topologies and modulation strategies. However, these works were scattered, and the relationship among these topologies and modulation strategies had not been revealed. This book intends to describe systematically the soft-switching techniques for pulse-width modulation (PWM) full-bridge converters, including the topologies, control and design, and it reveals the relationship among the various topologies and PWM strategies previously proposed by other researchers. The book not only presents theoretical analysis, but also gives many detailed design examples of the converters.

Geothermal Heat Pump and Heat Engine Systems. Theory And Practice
A unique approach to the study of geothermal energy systems This book takes a unique, holistic approach to the interdisciplinary study of geothermal energy systems, combining low, medium, and high temperature applications into a logical order. The emphasis is on the concept that all geothermal projects contain common elements of a «thermal energy reservoir» that must be properly designed and managed. The book is organized into four sections that examine geothermal systems: energy utilization from resource and site characterization; energy harnessing; energy conversion (heat pumps, direct uses, and heat engines); and energy distribution and uses. Examples are provided to highlight fundamental concepts, in addition to more complex system design and simulation. Key features: Companion website containing software tools for application of fundamental principles and solutions to real-world problems. Balance of theory, fundamental principles, and practical application. Interdisciplinary treatment of the subject matter. Geothermal Heat Pump & Heat Engine Systems: Theory and Practice is a unique textbook for Energy Engineering and Mechanical Engineering students as well as practicing engineers who are involved with low-enthalpy geothermal energy systems.
Commercial Management. Theory and Practice
Commercial Management: theory and practice defines the role of commercial management within project-oriented organisations, providing a framework for and helping to develop a critical understanding of the factors that influence commercial management practice. It also identifies generic aspects of this practice and provides a theoretical foundation to these activities, by reference to existing and emergent theories and concepts, as well as to relevant management best practice. The book is structured into four parts: Part 1 Introduction – Commercial Management in Project Environments explores the nature of commercial practice within project-oriented organisations at the buyer-seller interface. It presents a Commercial Management framework, which illustrates the multiple interactions and connections between the purchaser‘s procurement cycle and a supplier‘s bidding and implementation cycles. Additionally, it outlines the principle activities undertaken by the commercial function, identifies the skills and abilities that support these activities and reviews the theories and concepts that underpin commercial practice. Finally, it identifies areas of commonality of practice with other functions found within project-oriented organisations, plus sources of potential conflict and misunderstanding. Part 2 – Elements of Commercial Theory and Practice covers commercial leadership; exploring strategy; risk and uncertainty management; financial decision-making; and key legal issues. Part 3 – Approaches to Commercial Practice addresses best practice management; and commercial and contracting strategies and tactics. Finally, Part 4 – Case Studies offers two extended case studies: Football Stadia (the Millennium Stadium, Cardiff; the Emirates Stadium, Islington; and Wembley Stadium, London); and Heathrow Terminal 5. The book provides a one-stop-shop to the many topics that underpin commercial management practice from both a demand (buy-side) and a supply (sell-side) perspective. It will help develop an understanding of the issues influencing commercial management: leadership, strategy, risk, financial, legal, best practice management and commercial and contracting strategy and tactics. This book’s companion website is at www.wiley.com/go/lowecommercialmanagement and offers invaluable resources for both students and lecturers: • PowerPoint slides for lecturers on each chapter • Sample exam questions for students to practice • Weblinks to key journals and relevant professional bodies
Adaptive Filters. Theory and Applications
This second edition of Adaptive Filters: Theory and Applications has been updated throughout to reflect the latest developments in this field; notably an increased coverage given to the practical applications of the theory to illustrate the much broader range of adaptive filters applications developed in recent years. The book offers an easy to understand approach to the theory and application of adaptive filters by clearly illustrating how the theory explained in the early chapters of the book is modified for the various applications discussed in detail in later chapters. This integrated approach makes the book a valuable resource for graduate students; and the inclusion of more advanced applications including antenna arrays and wireless communications makes it a suitable technical reference for engineers, practitioners and researchers. Key features: • Offers a thorough treatment of the theory of adaptive signal processing; incorporating new material on transform domain, frequency domain, subband adaptive filters, acoustic echo cancellation and active noise control. • Provides an in-depth study of applications which now includes extensive coverage of OFDM, MIMO and smart antennas. • Contains exercises and computer simulation problems at the end of each chapter. • Includes a new companion website hosting MATLAB® simulation programs which complement the theoretical analyses, enabling the reader to gain an in-depth understanding of the behaviours and properties of the various adaptive algorithms.
TRIZ für Ingenieure. Theorie und Praxis des erfinderischen Problemlösens
TRIZ, sinngema? ubersetzt als Theorie des erfinderischen Problemlosens, ist eine machtige Methode, um aus dem Erfahrungsschatz fruherer Erkenntnisse aktuelle Probleme zu verstehen und zielgerichtet zu losen, mit denen Ingenieure in ihrer taglichen Arbeit konfrontiert sind, sei es bei der Entwicklung neuer oder bei der Verbesserung bestehender Produkte. Es gibt viele Ansatze zur Analyse von Problemen und zur Definition der Anforderungen an eine Losung; TRIZ vereint diese Ansatze konzeptionell und gibt daruber hinaus, im Gegensatz zu anderen Methoden, Ingenieursteams Werkzeuge an die Hand, mit denen – systematisch – Losungen fur gegebene Fragestellungen gefunden werden konnen. Damit ist TRIZ das Mittel der Wahl, um in Unternehmen und Forschungseinrichtungen Kreativitat und Innovationskraft zu fordern. Dieser leicht zugangliche Praxisfuhrer in die Welt von TRIZ entstand aus der langjahrigen Schulungs- und Beratungserfahrung der Autorin Karen Gadd. Auf einzigartig verstandliche und unterhaltsame Weise, unterstutzt durch speziell fur dieses Buch erstellte Illustrationen und Cartoons, gelingt es Karen Gadd, den Leserinnen und Lesern die TRIZ-Methode nahezubringen, so dass sie diese in der Praxis einsetzen konnen. Dabei werden die abstrakten Ansatze wie die Widerspruchsmatrix, Ressourcen-Checklisten und das Prinzip der Idealitat stets mit konkreten Beispielen und Fallstudien aus der Praxis untermauert.
