This text provides an introduction to the mathematical modeling and subsequent optimization of vehicle propulsion systems and their supervisory control algorithms. Automobiles are responsible for a substantial part of the world's consumption of primary energy, mostly fossil liquid hydrocarbons and the reduction of the fuel consumption of these vehicles has become a top priority. Increasing concerns over fossil fuel consumption and the associated environmental impacts have motivated many groups in industry and academia to propose new propulsion systems and to explore new optimization methodologies. This third edition has been prepared to include many of these developments. In the third edition, exercises are included at the end of each chapter and the solutions are available on the web.

Electrical engineering students are traditionally given but brief exposure to the important topic of electrical machines and transformers. This text/reference comprises a thorough and accessible introduction to the subject and this Second Edition contains more material on small machinery and a new chapter on the "energy conversiona a approach to calculation of magnetically developed forces. A circuit model is developed for each of the basic devices and the physical basis of each model is explained. Chapters are relatively independent of one another and follow the same general plan----coverage is broad and deep enough to permit flexibility in course design.

What determines how cities move on? The ever-increasing challenges to urban mobility come in many forms, and approaches to address them range from the technically ingenious to attempts to change travel behaviour. Key amongst factors essential to the success of any such approach is whether the urban environment proves to be fertile ground for the desired progress. Another vital determinant of success is how well individual measures to engineer the transport system interact with other developments. This leads to the principal subject of "Megacity Mobility Culture" the basic principles that determine the paths along which cities move. This book demonstrates that the concept of 'mobility culture' provides a framework for understanding the development of urban transport which transcends the boundaries between academic disciplines. Based on a discussion of the diversity of megacities worldwide, it" "provides help in navigating the complexity of megacity mobility culture. Experts from megacities around the world each take the reader on a journey to their own city and its mobility culture, giving a deeper insight into the unique evolutionary paths of mobility that these places have taken, and what lies before them. Whilst acknowledging the overwhelming diversity of cities worldwide, the authors also identify common denominators behind the evolution of urban transport systems - seven temperaments which are found in a unique mix in any given city, defining the character of its mobility culture.

The Institute for Mobility Research is a research facility of the BMW Group. It deals with future developments and challenges relating to mobility across all modes of transport, with automobility being only one aspect among many. Taking on an international perspective, ifmo's activities focus on social science and sociopolitical, economic and ecological issues, but also extend to cultural questions related to the key challenges facing the future of mobility. The work of the Institute is supported by an interdisciplinary board of renowned scientists and scholars, and by representatives of BMW, Deutsche Bahn, Lufthansa, MAN, Siemens and The World Bank.

Delving into the connections between renewable energy and economics on an international level, this book focuses specifically on hydropower and geothermal power production for use in the power intensive industry. It takes readily available government and international statistics to provide insight into how businesses and economists can interpret the factors that influence the growth of power intensive industries. It also discusses the CarbFix and SulFix projects that involve the injection of hydrogen sulphide (H2S), and carbon dioxide (CO2) back to reservoir as an emission reduction method. With improved engineering processes, both types of power generation are increasingly subject to economies of scale. These exciting technological developments have a great potential to change the way the world works, as the economy continues to rely so heavily on energy to drive production. Green energy is without a question going to be a major factor in our future, so studying it at its nascence is particularly exciting. This book is intended for academic researchers and students interested in current economic and environmental hot topics, as well as people interested in the inner workings of a possible new investment opportunity.

These conference proceedings contain contributions to one of Europe's largest annual conferences on energy efficiency and renewable energy. From two main fields - biomass and energy efficiency in buildings - contributions offer an insight into the research work and the scientific findings and developments of young researchers from all over the world. The papers were selected by a high-level scientific committee for oral presentation. They also communicate results, trends and opinions that will concern and influence the world's energy experts and policy makers over the next decades. The conference was held from 26-27 February 2014.

Computational studies on fuel cell-related issues are increasingly common. These studies range from engineering level models of fuel cell systems and stacks to molecular level, electronic structure calculations on the behavior of membranes and catalysts, and everything in between. This volume explores this range. It is appropriate to ask what, if anything, does this work tell us that we cannot deduce intuitively? Does the emperor have any clothes? In answering this question resolutely in the affirmative, I will also take the liberty to comment a bit on what makes the effort worthwhile to both the perpetrator(s) of the computational study (hereafter I will use the blanket terms modeler and model for both engineering and chemical physics contexts) and to the rest of the world. The requirements of utility are different in the two spheres. As with any activity, there is a range of quality of work within the modeling community. So what constitutes a useful model? What are the best practices, serving both the needs of the promulgator and consumer? Some of the key com- nents are covered below. First, let me provide a word on my 'credentials' for such commentary. I have participated in, and sometimes initiated, a c- tinuous series of such efforts devoted to studies of PEMFC components and cells over the past 17 years. All that participation was from the experim- tal, qualitative side of the effort.

During the last decade many new concepts have been proposed for improving the performance of power MOSFETs. The results of this research are dispersed in the technical literature among journal articles and abstracts of conferences. Consequently, the information is not readily available to researchers and practicing engineers in the power device community. There is no cohesive treatment of the ideas to provide an assessment of the relative merits of the ideas. "Advanced Power MOSFET Concepts" provides an in-depth treatment of the physics of operation of advanced power MOSFETs. Analytical models for explaining the operation of all the advanced power MOSFETs will be developed. The results of numerical simulations will be provided to give additional insight into the device physics and validate the analytical models. The results of two-dimensional simulations will be provided to corroborate the analytical models and give greater insight into the device operation.

The twin challenge of meeting global energy demands in the face of growing economies and populations and restricting greenhouse gas emissions is one of the most daunting ones that humanity has ever faced. Smart electrical generation and distribution infrastructure will play a crucial role in meeting these challenges. We would need to develop capabilities to handle large volumes of data generated by the power system components like PMUs, DFRs and other data acquisition devices as well as by the capacity to process these data at high resolution via multi-scale and multi-period simulations, cascading and security analysis, interaction between hybrid systems (electric, transport, gas, oil, coal, etc.) and so on, to get meaningful information in real time to ensure a secure, reliable and stable power system grid. Advanced research on development and implementation of market-ready leading-edge high-speed enabling technologies and algorithms for solving real-time, dynamic, resource-critical problems will be required for dynamic security analysis targeted towards successful implementation of Smart Grid initiatives. This books aims to bring together some of the latest research developments as well as thoughts on the future research directions of the high performance computing applications in electric power systems planning, operations, security, markets, and grid integration of alternate sources of energy, etc.

The present book was written to address the needs of those readers interested in wind energy converters. The authors have tried to strike a balance between a short book chapter and a very detailed book for experts in the field. There were three prime reasons behind doing so: first, the field is highly interdisciplinary and requires a more accessible format for non-experts. The second reason for this more compact version is that both authors have encountered many students and technically oriented people who were searching for this type of book on wind energy. The third reason and motivation for writing this book was to provide some initial information to people who are embarking on a career in the wind industry. It is this group of people that the present book is targeted at.

Fuel cell technology is quite promising for conversion of chemical energy of hydrocarbon fuels into electricity without forming air pollutants. There are several types of fuel cells: polymer electrolyte fuel cell (PEFC), phosphoric acid fuel cell (PAFC), molten carbonate fuel cell (MCFC), solid oxide fuel cell (SOFC), and alkaline fuel cell (AFC). Among these, SOFCs are the most efficient and have various advantages such as flexibility in fuel, high reliability, simple balance of plant (BOP), and a long history. Therefore, SOFC technology is attracting much attention as a power plant and is now close to marketing as a combined heat and power generation system. From the beginning of SOFC development, many perovskite oxides have been used for SOFC components; for example, LaMnO -based oxide for the cathode and 3 LaCrO for the interconnect are the most well known materials for SOFCs. The 3 current SOFCs operate at temperatures higher than 1073 K. However, lowering the operating temperature of SOFCs is an important goal for further SOFC development. Reliability, durability, and stability of the SOFCs could be greatly improved by decreasing their operating temperature. In addition, a lower operating temperature is also beneficial for shortening the startup time and decreasing energy loss from heat radiation. For this purpose, faster oxide ion conductors are required to replace the conventional Y O -stabilized ZrO 2 3 2 electrolyte. A new class of electrolytes such as LaGaO is considered to be 3 highly useful for intermediate-temperature SOFCs.

This book covers a range of devices that use piezoelectricity to convert mechanical deformation into electrical energy and relates their output capabilities to a range of potential applications. Starting with a description of the fundamental principles and properties of piezo- and ferroelectric materials, where applications of bulk materials are well established, the book shows how nanostructures of these materials are being developed for energy harvesting applications. The authors show how a nanostructured device can be produced, and put in context some of the approaches that are being investigated for the development of nanostructured piezoelectric energy harvesting devices, also known as nanogenerators. There is growing interest in strategies for energy harvesting that use a variety of existing and well-known materials in new morphologies or architectures. A key change of morphology to enable new functionality is the nanostructuring of a material. One area of particular interest is self-powered devices based on portable energy harvesting. The charging of personal electronic equipment and other small-scale electronic devices such as sensors is a highly demanding environment that requires innovative solutions. The output of these so-called nanogenerators is explained in terms of the requirements for self-powered applications. The authors summarise the range of production methods used for nanostructured devices, which require much lower energy inputs than those used for bulk systems, making them more environmentally friendly and also compatible with a wide range of substrate materials.

The rapid growth of the Asian urban population concentrates on a few large cities, turning them into giant megacities. Despite new theoretical insights into the benefits of megacities, the emerging Asia is facing a daunting challenge concerning the management of infrastructure and services in their megacities. The deteriorating urban mobility is the most difficult challenge with respect to the sharp increase in vehicle numbers and to inadequate and poorly managed road infrastructure. Public transport, a sustainable mode of mobility, is subjected to a vicious cycle of poor service, decreasing ridership and lower investment. Despite various policy initiatives, the situation has not improved. The scale and growth pattern of Asian megacities have distinctive features which generate a unique set of challenges and opportunities. New perspectives are needed to effectively address the transportation problems making the best use of available opportunities. This book, which is a result of an international collaborative research, addresses these challenges by providing insightful analysis and novel viewpoints.

Some vanguard companies have evolved to a higher level of decentralization originating in the enabling-and-autonomy paradigm. A new kind of deep leadership is practiced by these spirit-driven organizations. This book brings together theory and case studies to cover historical origins and developments of both types of decentralization.

The 21st century has seen shipping evolve from a fundamental transport industry into an asset which is at the mercy of speculative flows and business cycles. This structural shift has a number of important ramifications for the business of shipping as well as for investment strategy. This ground breaking text develops a new macroeconomic approach to maritime economics, with an emphasis on the individual shipping markets and their interdependence, in order to arm the reader with a more comprehensive understanding of the way modern shipping markets function and enable the making of critical decisions such as when to buy and sell ships and when to be in the spot or the period market.Karakitsos and Varnavides bring together their wealth of experience in shipping, finance and academia to make a number of key contributions to the study of maritime economics including: -Viewing Freight rates as asset prices determined as a bargaining game between charterers and owners who form expectations of future demand and supply to create a dynamic analysis of freight rates.-Theorising ships as assets, where prices are determined by demand and supply. -Explaining how the demand for vessels is derived as a dynamic problem of fleet capacity expansion.-Integrating the supply and the expectations approaches to shipping cycles.-Explaining how shipping cycles are caused by business cycles and expectations in demand by integrating maritime economics with macroeconomics.Maritime Economics: A Macroeconomic Approach is divided into three distinct parts; Part I analyses the micro-foundations of maritime economics, by deriving the demand and supply functions in the freight (spot and period), shipyard, second-hand and scrap markets. Part II reviews the efficiency of shipping markets and the theory of business and shipping cycles. Part III analyses the financialisation of shipping markets, the constraints of ship finance, the interaction between business and shipping cycles, and offers a case study of how decisions should be taken.This key text is indispensable reading for advanced undergraduate students studying maritime economics or shipping degrees as well as for professionals working in the shipping industry or in the financial sector.

Microfluidic fuel cells and batteries represent a special type of electrochemical power generators that can be miniaturized and integrated in a microfluidic chip.

It is hoped that the content will entice and enable new research groups and engineers to rapidly gain traction in their own laboratories towards the development of next generation microfluidic electrochemical cells.

The world is witnessing a rapid growth in wind and other renewable based electricity generation due to environmental concerns associated with electricity generation from the conventional sources. Wind power behaves quite differently than conventional electric power generating units due to its intermittent and diffuse nature. System planners and operators face the variability and uncertainty of wind power availability, and therefore, encounter considerable challenges in making decisions to maintain the adequacy and security of wind integrated power systems. This volume intends to bring out the original research work of researchers from academia and industry in understanding, quantifying and managing the risks associated with the uncertainty in wind variability in order to plan and operate a modern power system integrated with a significant proportion of wind power generation with an acceptable level of reliability. Accurate modeling of wind power variability and proper incorporation of the models in reliability and risk evaluation is very important for the planning and operation of electric power systems, and will play a crucial role in defining the requirement of various types of resources and services, such as storage and ancillary services in power systems.

Electromagnetic vibration transducers are seen as an effective way of harvesting ambient energy for the supply of sensor monitoring systems. Different electromagnetic coupling architectures have been employed but no comprehensive comparison with respect to their output performance has been carried out up to now. "Electromagnetic Vibration Energy Harvesting Devices" introduces an optimization approach which is applied to determine optimal dimensions of the components (magnet, coil and back iron). Eight different commonly applied coupling architectures are investigated. The results show that correct dimensions are of great significance for maximizing the efficiency of the energy conversion. A comparison yields the architectures with the best output performance capability which should be preferably employed in applications. A prototype development is used to demonstrate how the optimization calculations can be integrated into the design flow." Electromagnetic Vibration Energy Harvesting Devices" targets the designer of electromagnetic vibration transducers who wishes to have a greater in-depth understanding for maximizing the output performance.

The modern financial system was developed to support the rapid economic growth that took off about 200 years ago with the phenomenal amounts of cheap energy made available through the exploitation of fossil fuels. As a result, its viability is completely dependent upon the continuation of that growth. Unfortunately, the more recent fossil fuel discoveries, especially for oil, have tended to have lower production levels than earlier ones. In addition, greater amounts of energy are required to extract the fossil fuels leading to less net energy available for society. The Energy Return On Investment (EROI) for oil has fallen from 30:1 in the 1970's to 10:1 today. Thus, newer energy finds produce lower extraction rates and more of the energy provided is offset by the energy used in the extraction processes. The result has been economic stagnation or even contraction, with growth in China and India etc. only possible due to the extensive use of local coal reserves, and recession-induced drops in OECD country energy use. Renewable sources of energy will not be able to expand fast enough to replace the 87% of energy supplies provided by fossil fuels, and apart from hydro and wind, tend to have very low EROI rates. They are also critically dependent upon the cheap energy infrastructure provided by fossil fuels. The phenomenal amounts of path-dependent energy infrastructure will also greatly inhibit any move away from fossil fuels.

Without continued economic growth there will not be the extra output to fund loan interest payments, nor the revenue and profit growth to support share price/earnings multiples. The financial system acts as a time machine, creating asset prices based upon perceptions of the future. As an increasing percentage of investors come to accept the future reality of at best, financial asset prices will fall to reflect a realistic future. The resulting crash will remove the underpinnings of the banking, brokerage, mutual fund, pension fund, and insurance industries. The comfortable futures of many will be shown to have been based upon a mirage of future growth that will not take place. With the financial system acting as the critical coordination system of the global economy, its crash will also intensify economic problems. Written by a retired financial industry executive with over 25 years of experience, this book describes how the crisis will affect different regions and industries to help identify the career and investment choices which may provide a relative safe harbour.
