Book Description
A major contribution to one of the central themes in social theory, this book integrates multiple case studies of the relationship between water control and social organization. Substantial in empirical detail and featuring powerful theoretical extensions, Scarborough's analysis encompasses early Harappan society in South Asia, highland Mexico, the Maya lowlands, north-central Sri Lanka, the prehistoric American Southwest, and Bronze Age Greece. This book is the first longitudinal study to consider water management worldwide since Karl Wittfogel put forth his "hydraulic societies" hypothesis nearly two generations ago, and it draws together the diverse debates that seminal work inspired. In so doing, Scarborough offers new models for cross-cultural analysis and prepares the ground for new examinations of power, centralization, and the economy.

Book Description
Professor Emanuel uses clear presentation to compare and facilitate understanding of two seminal standards, The IEEE Std. 1459 and The DIN 40110-2:2002-11. Through critical analysis of the most important and recent theories and review of basic concepts, a highly accessible guide to the essence of the standards is presented. Key features: Explains the physical mechanism of energy flow under different conditions: single- and three-phase, sinusoidal and nonsinusoidal, balanced and unbalanced systems Starts at an elementary level and becomes more complex, with six core chapters and six appendices to clarify the mathematical aspects Discusses and recommends power definitions that played a significant historical role in paving the road for the two standards Provides a number of original unsolved problems at the end of each chapter Introduces a new nonactive power; the Randomness power. Power Definitions and the Physical Mechanism of Power Flow is useful for electrical engineers and consultants involved in energy and power quality. It is also helpful to engineers dealing with energy flow quantification, design and manufacturing of metering instrumentation; consultants working with regulations related to renewable energy courses and the smart grid; and electric utility planning and operation engineers dealing with energy bill structure. The text is also relevant to university researchers, professors, and advanced students in power systems, power quality and energy related courses.

Book Description
This book discusses the major aspects of load flow, optimization, optimal load flow, and culminates in modern heuristic optimization techniques and evolutionary programming. In the deregulated environment, the economic provision of electrical power to consumers requires knowledge of maintaining a certain power quality and load flow. Many case studies and practical examples are included to emphasize real-world applications. The problems at the end of each chapter can be solved by hand calculations without having to use computer software. The appendices are devoted to calculations of line and cable constants, and solutions to the problems are included throughout the book.

Book Description
Imagine feeling as though the world is working with you, not against you. Imagine a day in which you make every green light and slip effortlessly into a parking spot in the most crowded part of town. You make a To Do list, and the people on it call you first. You turn on the radio just in time to hear the exact information you need. These meaningful coincidences, called synchronicity, are sure signs you are "in the flow." Based on new, groundbreaking research, The Power of Flow goes beyond other books on synchronicity to provide you with sixteen easy-to-understand techniques that allow you to access this magical state of flow and create a richer, more satisfying life.

Book Description
This rigorous tutorial is aimed at both power system professionals and electrical engineering students. Breaking down the complexities of load flow analysis into a series of short, focused chapters, the book develops each of the major algorithms used, covers the handling of generators and transformers in the analysis process, and details how these algorithms can be deployed in powerful software. Having read the book, and EE student or engineer will have all the tools necessary to predict load usage and prevent overloads, blackouts, and brownouts.

Book Description
Power system modelling and scripting is a quite general and ambitious title. Of course, to embrace all existing aspects of power system modelling would lead to an encyclopedia and would be likely an impossible task. Thus, the book focuses on a subset of power system models based on the following assumptions: (i) devices are modelled as a set of nonlinear differential algebraic equations, (ii) all alternate-current devices are operating in three-phase balanced fundamental frequency, and (iii) the time frame of the dynamics of interest ranges from tenths to tens of seconds. These assumptions basically restrict the analysis to transient stability phenomena and generator controls. The modelling step is not self-sufficient. Mathematical models have to be translated into computer programming code in order to be analyzed, understood and “experienced”. It is an object of the book to provide a general framework for a power system analysis software tool and hints for filling up this framework with versatile programming code. This book is for all students and researchers that are looking for a quick reference on power system models or need some guidelines for starting the challenging adventure of writing their own code.

Book Description
In the subject of power systems, authors felt that a re-look is necessary at some conventional methods of analysis. In this book, the authors have subjected the time-honoured load flow to a close scrutiny. Authors have discovered and discussed a new load flow procedure – Modular Load Flow. Modular Load Flow explores use of power – a scalar – as source for electrical circuits which are conventionally analysed by means of phasors – the ac voltages or currents. The method embeds Kirchhoff’s circuit laws as topological property into its scalar equations and results in a unique wonderland where phase angles do not exist! Generators are shown to have their own worlds which can be superimposed to obtain the state of the composite power system. The treatment is useful in restructured power systems where stakeholders and the system operators may desire to know individual generator contributions in line flows and line losses for commercial reasons. Solution in Modular Load Flow consists of explicit expressions which are applicable with equal ease to well-conditioned, ill-conditioned and very low voltage situations. It is found to be computationally much faster than the iterative load flows and indicates promise for online application. Indian blackouts of July 30 and 31, 2012 are analysed using an equivalent grid network to indicate its utility. Besides its ability to deal with ground reality in power systems, Modular Load Flow points to a theory that unveils interesting mathematical structures which should entice avid researchers. Second author has had first author as teacher and third author as student. The lecture notes therefore reflect ethos of three generations of teachers.
