The subject of this book is an important and diverse field of electric machines and drives. The twelve chapters of the book written by renowned authors, both academics and practitioners, cover a large part of the field of electric machines and drives. Various types of electric machines, including three-phase and single-phase induction machines or doubly fed machines, are addressed. Most of the chapters focus on modern control methods of induction-machine drives, such as vector and direct torque control. Among others, the book addresses sensorless control techniques, modulation strategies, parameter identification, artificial intelligence, operation under harsh or failure conditions, and modelling of electric or magnetic quantities in electric machines. Several chapters give an insight into the problem of minimizing losses in electric machines and increasing the overall energy efficiency of electric drives.

Addressing faith as it is lived, rather than as a system of doctrine, F. Gerrit Immink emphasizes that having faith means more than assenting to certain opinions about God; it involves a dynamic relationship, or dialogue, with God. As he investigates the practice of faith, Immink holds together the poles of divine activity and human experience, external Word and indwelling Spirit. At its heart, this book is about God. How can faithful people speak about God and understand God's presence? Well versed in both philosophical analysis and the theological tradition, the author argues for an understanding of God as a speaking, acting person, genuinely experienced in faith. In so doing, he issues a compelling plea to reevaluate the theoretical foundations of practical theology. Applying his work particularly to the theories of preaching and pastoral care, Immink brings to bear insights garnered from years as an academic theologian, as the dean of a theological seminary, and as a minister. Scholars, ministers, and seminary students alike will benefit from his careful reflections on the Christian life of faith.

In this age of working mothers, the role of fathering is often overlooked. This book illuminates the realitites of fathering by presenting the results of a unique empirical study conducted over four decades and covering four generations. Through case studies and data analysis, John Snarey demonstrates that men's care for their families reaps immense and long-lasting benefits - for themselves, for their offspring, and for future generations.
