The Field Orientation Principle (FOP) constitutes a fundamental concept behind the modern technology of high-performance, vector-controlled drive systems with AC motors. The recent intense interest in these systems has been spawned by the widespread transition from DC to AC drives in industry. Induction motors, industry's traditional workhorses, are particularly well suited for FOP-based vector control. The Field Orientation Principle in Control of Induction Motors presents the FOP in a simple, easy-to-understand framework based on the space-vector dynamic model of the induction machine. Relationships between the classic phasor equivalent circuits of the motor and their vector counterparts are highlighted. A step-by-step derivation of dynamic equations of the motor provides a formal background for explanation of the basic approaches to vector control. In addition, the author presents scalar control methods for low-performance drives as an intermediate stage between uncontrolled and high-performance drives. The reader will also find a full chapter devoted to power inverters, which constitute an important component of adjustable speed AC drive systems, and a review of associated issues such as observers of motor variables, parameter estimation, adaptive tuning, and principles of the position and speed control of field-oriented induction motors. With a wealth of numerical examples and computer simulations illustrating the ideas and techniques discussed and an extensive bibliography, The Field Orientation Principle in Control of Induction Motors is a practical resource and valuable reference for researchers and students interested in motor control, power and industrial electronics, and control theory.

Induction - the first year of a teacher's career - is a crucial, and potentially difficult, period. This book is the work of a well-known and highly respected team of experts on the subject and is based on a comprehensive nationwide research project into the implementation and effectiveness of the latest statutory regulations covering induction in England. It includes not only findings from this research, but also numerous ideas from, and examples of, best practice. Including case studies from primary and secondary schools, in the state and private sectors, this book raises awareness of the complexities entailed in inducting new teachers, addresses the issues, dilemmas and problems of induction and celebrates the achievements of the national induction policy. Its insights provide an invaluable guide to the effective implementation of induction in schools.

A broad class of accelerators rests on the induction principle whereby the accelerating electrical fields are generated by time-varying magnetic fluxes. Particularly suitable for the transport of bright and high-intensity beams of electrons, protons or heavy ions in any geometry (linear or circular) the research and development of induction accelerators is a thriving subfield of accelerator physics. This text is the first comprehensive account of both the fundamentals and the state of the art about the modern conceptual design and implementation of such devices. Accordingly, the first part of the book is devoted to the essential features of and key technologies used for induction accelerators at a level suitable for postgraduate students and newcomers to the field. Subsequent chapters deal with more specialized and advanced topics.

Every mathematician and student of mathematics needs a familiarity with mathematical induction. This volume provides advanced undergraduates and graduate students with an introduction and a thorough exposure to these proof techniques. 2017 edition.

This leadership induction program focuses on the importance of an effective induction process in the recruitment, development, and retention of school principals.

Induction chemotherapy, as part of an integrated plan of management for locally advanced cancers, is being practiced throughout the world, but frequently teams are unaware of the work being undertaken in other institutions. This book aims to present the full range of management techniques used in induction chemotherapy within one accessible volume. It provides up-to-date information on pioneering and cutting edge practices and documents the advantages of integrated treatment schedules. Patient selection is discussed, and each of the cancer types for which induction therapy has proved important is considered in detail. All who are responsible for the treatment of patients with locally advanced cancers will find this book to be an invaluable source of information. It will be particularly interesting for specialist oncologists aiming to set up fully comprehensive cancer centers and for health administrators wishing to learn about the benefits of establishing such centers in strategic locations.

Develop induction programs that focus on improved practice rather than just survival skills! "All beginning teachers face significant challenges during their induction into the teaching profession. This book provides a cogent, thoughtful, and practical guide to working in the areas of teacher induction and mentoring, and is a must read for academics, program developers, and practitioners alike." Sandra Odell, Professor University of Nevada, Las Vegas "Bartell argues that induction is about more than retaining teachers. It is about helping all teachers become more professional and better at what they do . . . and, most important, it is about improving student learning." From the Foreword by Linda Darling-Hammond Charles E. Ducommun, Professor of Education Stanford University The first few years of teaching are the most challenging. During these years, teachers are most likely to become discouraged and disillusioned. Yet these early years are also the time when teachers establish practices that last throughout their careers. Cultivating High-Quality Teaching Through Induction and Mentoring focuses on new teachers′ needs while emphasizing high-quality teaching through the use of standards-based teaching, teacher assessments, and reflective practice. Through extensive research, Carol Bartell has identified the critical elements in shaping induction policies that lead to teacher retention and improved student achievement. Because teachers begin with different levels of preparation, Bartell addresses how to adjust programs to meet differing needs in a variety of school contexts. Bridging the gap between knowledge and practice, this handbook includes: A description of the challenges that new teachers face The key elements of an effective induction plan The role of mentoring in a successful induction program Information on induction in the most challenging setting-urban schools Models and approaches to assessment during the induction period Throughout, this book emphasizes a developmental approach to encouraging teachers to a higher level of practice that extends beyond the usual survival skills. Don′t just prepare teachers to teach, prepare them to teach better!

Induction Machines Handbook: Steady State Modeling and Performance offers a thorough treatment of steady-state induction machines (IM), the most used electric motor (generator) in rather constant or variable speed drives, forever lower energy consumption and higher productivity in basically all industries, from home appliances, through robotics to e-transport and wind energy conversion.
