Energy Efficiency and Management of Power and Energy Systems introduces students and researchers to a broad range of power system management challenges, technologies, and solutions. This book begins with an analysis of system technology's current state, the most pressing problems, and the background to challenges in integrating renewable energy sources. Technologies including smart grids, green building, and worker requirements are covered. Subsequent chapters break down potential management solutions, including specific problem-solving for solar, wind, and hybrid systems. Finally, specific case studies from a global geographical range zero in on critical questions facing the present industr...
Despite advances in modern communication and the proliferation of information, there remain areas of the world about which little is known. One such place is Somalia. The informed public is aware of a political meltdown and consequent chaos there, but few comprehend the causes of this tragic crisis. This new edition covers Somalia's origin, history, culture, and language, as well as current economic and political issues. The alphabetical arrangement of this Dictionary, with a complete chronology, list of acronyms, and in-depth bibliography provide useful information about the country in a convenient format. A vital addition to reference collections supporting undergraduate and graduate programs on Africa and the Middle East, international relations, and economics- a useful fact-filled compendium for government and public libraries, NGO's, and other special libraries
Sufi Aesthetics argues that the interpretive keys to erotic Sufi poems and their medieval commentaries lie in understanding a unique perceptual experience. Using careful analysis of primary texts, Cyrus Ali Zargar explores the theoretical and poetic pronouncements of two major Muslim mystics, Muhyi al-Din ibn al-'Arabi (d. 1240) and Fakhr al-Din 'Iraqi (d. 1289), under the premise that behind any literary tradition exist organic aesthetic values. The complex assertions of these Sufis appear not as abstract theory, but as a way of seeing all things, including the sensory world. The Sufi masters, Zargar asserts, shared an aesthetic vision quite different from those who have often studied them....
This book traces the evolution of Sufism from the formative period to the present.
As the world moves toward renewable energy sources to combat environmental and power distribution issues, there has been a resurgence of interest in induction generators, particularly in their use in wind and hydropower generation systems. Induction machines operating as generators are rugged and cost effective, and with recent advances in control and optimization, the control design aspects are now moving from the laboratory to the desks of practicing engineers. Renewable Energy Systems: Design and Analysis with Induction Generators presents the first comprehensive exposition of induction machines used for power generation. Focusing on renewable energy applications, the authors address virt...
The Studies in the History and Culture of the Islamic Orient (STIO) is the series of “Supplements” to the journal Der Islam. Both are published by the Section for the History and Culture of the Near East in the Asian-African Institute of the University of Hamburg. The Section was established in 1908, before the foundation of the University of Hamburg. Under its first Director, C.H. Becker, it was the first academic centre in Germany in which teaching and research concentrated on the historical and cultural aspects of the Islamic world, and not just on philological issues. Many of Germany’s leading authorities in Islamic Studies have studied and/or taught here. The “Supplements” have maintained the same high quality and met the same high demands as the journal Der Islam and have published numerous studies on the history and culture of the Islamic world which have represented milestones in their relevant fields. The “New Series” of Supplements appearing since 2004 carries this tradition forward and provides a platform for publishing studies on the history and culture of the Islamic world from the beginnings of Islam up to the present day.
"A concise but authentic account." — Islamic Review. The first concise history of Sufism to appear in any language, this work remains among the best. A noted scholar offers insights into every aspect of Sufism, from interpretation of the word of God and the life of the Prophet to the theorists of Sufism, the structure of Sufi theory and practice, and more.
Wind Energy Systems: Modeling, Analysis and Control with DFIG provides key information on machine/converter modelling strategies based on space vectors, complex vector, and further frequency-domain variables. It includes applications that focus on wind energy grid integration, with analysis and control explanations with examples. For those working in the field of wind energy integration examining the potential risk of stability is key, this edition looks at how wind energy is modelled, what kind of control systems are adopted, how it interacts with the grid, as well as suitable study approaches. Not only giving principles behind the dynamics of wind energy grid integration system, but also examining different strategies for analysis, such as frequency-domain-based and state-space-based approaches. - Focuses on real and reactive power control - Supported by PSCAD and Matlab/Simulink examples - Considers the difference in control objectives between ac drive systems and grid integration systems
