Thanks to advances in power electronics device design, digital signal processing technologies and energy efficient algorithms, ac motors have become the backbone of the power electronics industry. Variable frequency drives (VFD's) together with IE3 and IE4 induction motors, permanent magnet motors, and synchronous reluctance motors have emerged as a new generation of greener high-performance technologies, which offer improvements to process and speed control, product quality, energy consumption and diagnostics analytics. Primarily intended for professionals and advanced students who are working on sensorless control, predictive control, direct torque control, speed control and power quality and optimisation techniques for electric drives, this edited book surveys state of the art novel control techniques for different types of ac machines. The book provides a framework of different modeling and control algorithms using MATLAB (R)/Simulink (R), and presents design, simulation and experimental verification techniques for the design of lower cost and more reliable and performant systems.

Fazlur Rahman's "Islam" is aptly titled, in that this slim volume constitutes an incisive and surprisingly comprehensive history and analysis of Islam--its history, its conflicts, its legacy--and its prospects. From Mohammed to the late twentieth century, Rahman traces the development of Islam as a religion and, more importantly, as an intellectual tradition, offering both an easily understood introduction to the faith and an impassioned argument for its future direction.

"Major Themes of the Qur'an" is Fazlur Rahman's introduction to one of the richest texts in the history of religious thought. In this classic work, Rahman unravels the Qur'an's complexities on themes such as God, society, revelation, and prophecy with the deep attachment of a Muslim educated in Islamic schools and the clarity of a scholar who taught for decades in the West.

"Generations of scholars have profited from Rahman's] pioneering scholarly work by taking the questions he raised and the directions he outlined to new destinations."--Ebrahim Moosa, from his new foreword

"The religious future of Islam and the future of interfaith relationship . . . will be livelier and saner for the sort of Quranic centrality which "Major Themes of the Qur'an" exemplifies and serves."--Kenneth Cragg, "Middle East"" Journal"

"There shines through a] rare combination of balanced scholarly judgment and profound personal commitment. . . . Rahman is] eager to open up the mysteries of the Qur'an to a shrinking world sorely in need of both moral regeneration and better mutual understanding."--Patrick D. Gaffney, "Journal of Religion"

"I can't think of any book more important, still, than "Major Themes of the Qur'an.""--Michael Sells, author of "Approaching the Qur'an"

This longstanding and highly regarded volume is the first to explore the doctrine of prophetic revelation, a critical and definitive area of Islamic religious and political thought. In it, the esteemed Islamic scholar Fazlur Rahman traces the inception of this doctrine from ancient Greek texts, its interpretation and elaboration by Muslim philosophers in order to suit their vision of the Prophet, and, finally, the varying degrees of acceptance of these convergent ideas by the Muslim orthodoxy.
The latest edition of this classic text includes a new foreword by Islamic studies expert Michael Sells, confirming "Prophecy in Islam" as the best source on its subject after more than half a century.

This authoritative book argues that what is considered today to be Islamic fundamentalism is inconsistent with the true meaning of this faith. Rahman demonstrates that the true roots of Islamic teachings advocate adaptability, creativity, and innovation.

From the Foreword: 'this "Concordance of the Qur'an in English" satisfies a paramount need of those - and there are millions of them - who have no command of the Arabic language and yet desire to understand the Qur'an. The benefit derivable from English translations of the Sacred Book is, in principle, limited because, first, the Qur'an is not a 'book' but a collection of passages revealed to Muhammad over a period of about twenty-three years and, second, because the Qur'an is not really translatable. This does not mean that the Qur'an should not be translated. It does mean that translations lose much in tone and nuance, let alone the incommunicable beauty, grandeur, and grace of the original...The main distinction of Hana Kassis' concordance, in my view, is that it utilizes the semantic structure of Arabic vocabulary itself in revealing the meaning of the Qur'an on any given issue, point or concept. A reader who looks in the index of this concordance for a word which he has encountered in reading an English translation of the Qur'an - the word pride, for example - is directed immediately to the roots of the Arabic, Qur'anic terms for pride. At tne entries for these Arabic roots, all the derivative forms are shown, and the verses of the Qur'an in which they appear are there listed in translation...I am confident that any person who is sincerely interested in understanding the Qur'an and appreciating the nuances of its diction and shades of its meaning can satisfy his need more fully with this book than in any way short of developing a real command over the Arabic language itself' - Fazlur Rahman, Professor of Islamic Thought, University of Chicago.

"As Professor Fazlur Rahman shows in the latest of a series of important contributions to Islamic intellectual history, the characteristic problems of the Muslim modernists--the adaptation to the needs of the contemporary situation of a holy book which draws its specific examples from the conditions of the seventh century and earlier--are by no means new. . . . In Professor Rahman's view the intellectual and therefore the social development of Islam has been impeded and distorted by two interrelated errors. The first was committed by those who, in reading the Koran, failed to recognize the differences between general principles and specific responses to 'concrete and particular historical situations.' . . . This very rigidity gave rise to the second major error, that of the secularists. By teaching and interpreting the Koran in such a way as to admit of no change or development, the dogmatists had created a situation in which Muslim societies, faced with the imperative need to educate their people for life in the modern world, were forced to make a painful and self-defeating choice--either to abandon Koranic Islam, or to turn their backs on the modern world."--Bernard Lewis, "New York Review of Books"
"In this work, Professor Fazlur Rahman presents a positively ambitious blueprint for the transformation of the intellectual tradition of Islam: theology, ethics, philosophy and jurisprudence. Over the voices advocating a return to Islam or the reestablishment of the Sharia, the guide for action, he astutely and soberly asks: What and which Islam? More importantly, how does one get to 'normative' Islam? The author counsels, and passionately demonstrates, that for Islam to be actually what Muslims claim it to be--comprehensive in scope and efficacious for every age and place--Muslim scholars and educationists must reevaluate their methodology and hermeneutics. In spelling out the necessary and sound methodology, he is at once courageous, serious and profound."--Wadi Z. Haddad, "American-Arab Affairs"
