Cross-layer design seeks to enhance the capacity of wireless networks significantly through the joint optimization of multiple layers in the network, primarily the physical (PHY) and medium access control (MAC) layers. Although there are advantages of such design in wireline networks as well, this approach is particularly advantageous for wireless networks due to the properties (such as mobility and interference) that strongly affect performance and design of higher layer protocols. This unique monograph is concerned with the issue of cross-layer design in wireless networks, and more particularly with the impact of node-level multiuser detection on such design. It provides an introduction to this vibrant and active research area insufficiently covered in existing literature, presenting some of the principal methods developed and results obtained to date. Accompanied by numerous illustrations, the text is an excellent reference for engineers, researchers and students working in communication networks.

The study of complex dynamic processes governed by nonlinear and nonstationary characteristics is a problem of great importance in the analysis and control of power system oscillatory behavior. Power system dynamic processes are highly random, nonlinear to some extent, and intrinsically nonstationary even over short time intervals as in the case of severe transient oscillations in which switching events and control actions interact in a complex manner. Phenomena observed in power system oscillatory dynamics are diverse and complex. Measured ambient data are known to exhibit noisy, nonstationary fluctuations resulting primarily from small magnitude, random changes in load, driven by low-scale motions or nonlinear trends originating from slow control actions or changes in operating conditions. Forced oscillations resulting from major cascading events, on the other hand, may contain motions with a broad range of scales and can be highly nonlinear and time-varying. Prediction of temporal dynamics, with the ultimate application to real-time system monitoring, protection and control, remains a major research challenge due to the complexity of the driving dynamic and control processes operating on various temporal scales that can become dynamically involved. An understanding of system dynamics is critical for reliable inference of the underlying mechanisms in the observed oscillations and is needed for the development of effective wide-area measurement and control systems, and for improved operational reliability.

Due to their environmental and efficiency characteristics fuel cells are promising technological solutions for many energy related applications (stationary power generation, vehicle propulsion, portable equipment). This book describes the economic dynamics of fuel cells by analyzing their diffusion perspectives as well as the strategic and organisational arrangements designed to promote their development. The costs, risks and economic stakes of fuel cell technologies require both a sustained involvement from public entities and the setting up of innovation networks with a large variety of heterogeneous actors. This context corresponds to a new space for technological competition located at the intersection between firms, networks and national/regional systems of innovation. The book presents a comprehensive analysis of this cooperation/competition phenomenon through different theoretical and empirical investigations.

Low-Power High-Speed ADCs for Nanometer CMOS Integration is about the design and implementation of ADC in nanometer CMOS processes that achieve lower power consumption for a given speed and resolution than previous designs, through architectural and circuit innovations that take advantage of unique features of nanometer CMOS processes. A phase lock loop (PLL) clock multiplier has also been designed using new circuit techniques and successfully tested. 1) A 1.2V, 52mW, 210MS/s 10-bit two-step ADC in 130nm CMOS occupying 0.38mm2. Using offset canceling comparators and capacitor networks implemented with small value interconnect capacitors to replace resistor ladder/multiplexer in conventional sub-ranging ADCs, it achieves 74dB SFDR for 10MHz and 71dB SFDR for 100MHz input. 2) A 32mW, 1.25GS/s 6-bit ADC with 2.5GHz internal clock in 130nm CMOS. A new type of architecture that combines flash and SAR enables the lowest power consumption, 6-bit >1GS/s ADC reported to date. This design can be a drop-in replacement for existing flash ADCs since it does require any post-processing or calibration step and has the same latency as flash. 3) A 0.4ps-rms-jitter (integrated from 3kHz to 300MHz offset for >2.5GHz) 1-3GHz tunable, phase-noise programmable clock-multiplier PLL for generating sampling clock to the SAR ADC. A new loop filter structure enables phase error preamplification to lower PLL in-band noise without increasing loop filter capacitor size.

Autonomous systems are one of the most important trends for the next generation of control systems. This book is the first to transfer autonomous systems concepts and intelligent agents theory into the control and operation environment of power systems.

Since the discovery of high temperature superconductors the scientific com nmnity has been very active in research on material and system development as well as on the basic understanding of the mechanism of superconductiv ity at high transition temperatures. Industrial groups joined in very soon as with these new materials the prospects for commercial application of super conductivity seemed to be more promising than ever. Materials processing was divided into film deposition and bulk preparation techniques, the latter including conductor fabrication and melt growth of monolithic samples as well. Because of the high impact of possible applications in energy technol ogy, wire and tape fabrication of the BSCCO superconductors is one of the most important fields, in addition to thin film technology for mobile comuni cation. Only since processes like IBAD and RABiTS TM were invented have film deposition techniques also become important for energy technology. In order to produce suitable conductors with material properties which meet the challenge imposed by energy technology, detailed understanding of the phase formation and physical properties of the high temperature super conductors is necessary. The goal of this book is on one hand to provide the basic information on phase formation and physical properties, and to give a short overview of the state of the art in conductor preparation and character ization. On the other hand it contains the author's own results in the field of preparation and characterization.

Environmental voluntary agreements (VAs) between regulators and polluters are becoming an increasingly relevant environmental policy instrument, thanks to their flexibility and consensual character. These agreements can assume a wide variety of forms and aims. Efficiency conditions and effectiveness in their use depend on their design, rules of implementation and framework conditions.

The book provides a comprehensive economic theory and analysis of environmental voluntary agreements, which takes into account the variety of forms and application situations characterizing this environmental policy instrument. Common methodologies, implementation rules and evaluation criteria for researchers, policy makers and business operators in the use of environmental voluntary agreements are discussed.

Case analysis complements the theoretical analysis. A European and an American approach to VAs are distinguished, and cases in China and Australia are also included. National and sector experiences are investigated in order to consider the full range of applications which the flexibility of VAs allows. Opportunities and risks in the use of VAs are examined. Their evaluation, also in comparison and in conjunction with other policy tools, is performed. VAs are still an instrument in evolution, so the trends in their design and enforcement rules are considered.

The authors are mainly economists and law scholars from Universities, research centers, environmental agencies and international institutions. The book is destined to researchers, scholars and graduate and post-graduate students. Most contributions can be of great interest also for environmental officers in various Public Administration administrative and technical bodies and for environmental managers and consultants.

While the basic operating principles of Helical Magnetic Flux Compression Generators are easy to understand, the details of their construction and performance limits have been described only in government reports, many of them classified. Conferences in the field of flux compression are also dominated by contributions from government (US and foreign) laboratories. And the government-sponsored research has usually been concerned with very large generators with explosive charges that require elaborate facilities and safety arrangements. This book emphasizes research into small generators (less than 500 grams of high explosives) and explains in detail the physical fundamentals, construction details, and parameter-variation effects related to them.

This volume in the acclaimed series Modern Aspects of Electrochemistry starts with a dedication to the late Professor Brian Conway who for 50 years helped to guide this series to its current prominence. The remainder of the volume is then devoted to the following topics: PEM fuel cells; the use of graphs in electrochemical reaction newtworks; nanomaterials in Lithium-ion batteries; direct methanolf fuel cells (two chapters); fuel cell catalyst layers. The book is for electrochemists, electrochemical engineers, fuel cell workers and energy generation workers.

The present study is a slightly revised version of my PhD thesis which was accepted at the Economics Department of Dresden University of Technology in July 2008. It has a long and a short history. For it began, as suggested theme, as a fundamental evaluation of evolutionary economics for ecological economics, asking, especially, for what the two ?elds actually constitutes and, eventually, relates. In several years of unfruitful dwelling, however, neither of these two young, non-mainstream ?elds proved as constituted at a fundamental level as yet. Rather, ecological economics, founded at the end of the 1980s as an attempt to combine social and natural s- ence approaches(in particular economics and ecology) to study especially long-run environmental problems in an encompassing manner, has mainly developed into an interdisciplinary research forum on environmental-economicissues. Particularly uni?edbycertainnormativestances sharedwithinits community, it constitutes, well understood, a new discpline of its own right, distinct from economics, with its own scienti?c standards, questions, methodologies and institutions (Baumgartner ] and Becker 2005). Modern evolutionaryeconomicson the other hand has been a quarter of a century after its inception with Nelson and Winter (1982) still a mainly h- erogeneousendeavor, linked by a (rather amorphous) common interest in economic "evolution" and a critical stance towards neoclassical mainstream economics, with a certain strength in applied studies on industrial dynamics (Heinzel 2004, 2006)."

Innovation is key to achieving a sustainable electricity system. New technologies and organizational changes can bring about more sustainable, climate-friendly electricity structures. Yet the dynamics of innovation are complex, and difficult to shape. This book, written by experts in the field, sets out to explore the dynamics, the drivers and the setting of innovation processes. Case studies on micro cogeneration, carbon capture and storage, consumer feedback, network regulation and emissions trading provide insights into innovation dynamics in the electricity system and are analyzed to derive strategic implications for innovation policies. A special focus is placed on drivers and barriers of change, and their consequences for shaping the innovation process. This book is an indispensable source of information for researchers and decision makers in energy and climate change as well as for lecturers and students interested in the principles and ramifications of electricity innovation dynamics.

In the coming 20 years, decentralised generation (DG) is expected to play an in- creasingly important role in the European electricity infrastructure and market. DG can be defined as small-scale generation connected to the distribution network or on the customer side of the meter. The application of DG is often highly loca- tion specific and depends on such diverse issues as the possibilities of technical implementation, resource availability, environmental aspects, social embedding of the project, regulation and market conditions. These factors vary considerably among technologies and among the ED Member States. The DECENT study (Decentralised Generation Technologies -Potentials, Suc- cess Factors and Impacts in the Liberalised ED Energy Markets (Joerss et al. 2002" was designed and carried out to identify the main barriers and success fac- tors to the implementation of DG projects within the ED and to formulate a num- ber of related recommendations to ED and Member State policy makers to en- hance the feasibility of DG projects within the internal energy market.

This book is a practical guide to the application of control benchmarking to real, complex, industrial processes. The variety of industrial case studies gives the benchmarking ideas presented a robust real-world attitude. The book deals with control engineering principles and economic and management aspects of benchmarking. It shows the reader how to avoid common problems in benchmarking and details the benefits of effective benchmarking.

I remember that the idea of this book emerged ?rst in Toulouse, during the Third Conference on Energy Markets - 3 years ago now. Anna Cret` ? gave a talk on a model dealing with seasonal gas storage in the USA, and Christian Von Hirschausen was her discussant. Both of them were devoting their efforts to understand the natural gas market in Europe and the relevant liberalization process. I found their interest in storage rather original, so I encouraged Anna to collect the most original cont- butions on this topic. Back in Milan with this idea in mind, she organized a working group at IEFE- Bocconi University, where she works. Then, during the following year, she - changed ideas and organized several meetings with the book's contributors. She regularly invited the most important Italian gas sector representatives to these me- ings, to make sure that the economic models were well suited to tackle the issues at stake in the European gas industry.

This new edition includes nearly 1000 new references.

Covering the development of field computation in the past forty years, this book is a concise, comprehensive and up-to-date introduction to methods for the analysis and synthesis of electric and magnetic fields. A broad view of the subject of field models in electricity and magnetism, ranging from basic theory to numerical applications, is offered. The approach throughout is to solve field problems directly from partial differential equations in terms of vector quantities.

Thermodynamics is not the oldest of sciences. Mechanics can make that claim. Thermodynamicsisaproductofsomeofthegreatestscienti?cmindsofthe19thand 20th centuries. But it is suf?ciently established that most authors of new textbooks in thermodynamics ?nd it necessary to justify their writing of yet another textbook. I ?nd this an unnecessary exercise because of the centrality of thermodynamics as a science in physics, chemistry, biology, and medicine. I do acknowledge, however, that instruction in thermodynamics often leaves the student in a confused state. My attempt in this book is to present thermodynamics in as simple and as uni?ed a form as possible. As teachers we identify the failures of our own teachers and attempt to correct them. Although I personally acknowledge with a deep gratitude the appreciation for thermodynamics that I found as an undergraduate, I also realize that my teachers did not convey to me the sweeping grandeur of thermodynamics. Speci?cally the s- plicity and the power that James Clerk Maxwell found in the methods of Gibbs were not part of my undergraduate experience. Unfortunately some modern authors also seem to miss this central theme, choosing instead to introduce the thermodynamic potentials as only useful functions at various points in the development.

Analog design at ultra-low supply voltages is an important challenge for the semiconductor research community and industry.

Analog Circuit Design Techniques at 0.5V covers challenges for the design of MOS analog and RF circuits at a 0.5 V power supply voltage. All design techniques presented are true low voltage techniques - all nodes in the circuits are within the power supply rails. The circuit implementations of body and gate input fully differential amplifiers are also discussed. These building blocks enable us to build continuous-time filters, track-and-hold circuits, and continuous-time sigma delta modulators.

Current books on low voltage analog design typically cover techniques for supply voltages down to approximately 1V. This book presents novel ideas and results for operation from much lower supply voltages and the techniques presented are basic circuit techniques that are widely applicable beyond the scope of the presented examples.

Analog Circuit Design Techniques at 0.5V is written for analog circuit designers and researchers as well as graduate students studying semiconductors and integrated circuit design.

This book reviews numerous research papers published in the last fifteen years in the area of current injection based rectifiers. A partial list of coverage includes analysis of various magnetic current injection devices, the third harmonic current injection, injection networks, and optimal current injection. The book will be of interest to professionals involved in design of low-harmonic three-phase rectifiers, as well as students and researchers.

Here is a new method for calculating heat transfer in coupled convective-conductive fluid-wall systems under periodical intensity oscillations in fluid flow. The true steady state mean value of the heat transfer coefficient must be multiplied by a newly defined coupling factor, which is always smaller than one and depends on the coupling parameters Biot number, Fourier number as well as dimensionless geometry and oscillation parameters. Includes characteristic solved problems, with tables and diagrams.

Scale modeling can play an important role in R&D. When engineers receive some ideas in new product development, they can test how the new design looks by bui- ing scale models and they can get an actual feeling with the prototype through their imagination. Professor Emori often said: "When children play with a toy airplane, their mind is wondering about the prototype airplane which they haven't ridden. " Children can use the scale model airplane as a means to enter into an imagi- tive world of wonder by testing in their own way how the actual airplane might function, how the actual airplane can maneuver aerodynamically, what might be the actual sound of a jet engine, how to safely land the actual airplane, and so on. This imagination that scale models can provide for children will help them later develop professional intuition. Physical scale models can never be entirely succe- fully replaced by computer screens where virtual models are displayed and fancy functions are demonstrated. Not only children but also adults can learn things by actually touching things only offered by physical models, helping all of us develop imagination and feeling eventually leading toward Kufu. Einstein's famous "thought experiments [11]," which helped him to restructure modern physics may possibly and effectively be taught by letting researchers play with scale models!? References 1. I.

Over the past three decades turbomachines experienced a steep increase in efficiency and performance. Based on fundamental principles of turbomachinery thermo-fluid mechanics, numerous CFD based calculation methods are being developed to simulate the complex 3-dimensional, highly unsteady turbulent flow within turbine or compressor stages. The objective of this book is to present the fundamental principals of turbomachinery fluid-thermodynamic design process of turbine and compressor components, power generation and aircraft gas turbines in a unified and compact manner. The book provides senior undergraduate students, graduate students and engineers in the turbomachinery industry with a solid background of turbomachinery flow physics and performance fundamentals that are essential for understanding turbomachinery performance and flow complexes.

This book provides an account of the field of synchronized Phasor Measurement technology, its beginning, its technology and its principal applications. It covers wide Area Measurements (WAM) and their applications. The measurements are done using GPS systems and eventually will replace the existing technology. The authors created the field about twenty years ago and most of the installations planned or now in existence around the world are based on their work.

Service Quality Regulation in Electricity Distribution and Retail provides a guide for regulatory authorities and postgraduate students alike, accompanying readers through the necessary steps for designing and implementing regulatory policy. It builds a bridge between the theoretical aspects of service quality regulation and country-specific applied mechanisms. The book offers examples as provided by regulatory authorities (including some not often available in the English language), and suggests best practices as elaborated by a number of international regulatory organizations.

The book is a comprehensive, clear, well-organized description of applied quality regulation in the electricity sector as it is, today. Advanced readers will also appreciate its survey of the most innovative regulatory mechanisms currently being employed (and tested) in European countries, as well as those that have been proposed in the literature.

Encouragement by colleagues and a considerable increase in the use of prob abilistic analyses since the publication of the German edition in 1987 have motivated this English version. A mere translation was inappropriate because a number of important studies completed in recent years had to be included, among them the assessment of the risks of five nuclear power plants in the United States of America and the German Risk Study, Phase B. The opportunity was taken to elaborate on some concepts which have gained importance of late such as accident management. An update of international safety goals was also made; however, this can only be a momentary view of a field subjected to frequent change. Thanks are due to the Springer-Verlag for the careful editing and production of the book. Kaln, Garching Ulrich Hauptmanns March 1990 Wolfgang Werner Preface to the German Edition With the increasing use of complex technologies there is a growing need to evaluate the associated risks. The methodology of probabilistic safety and risk analysis allows predictive valuation of risks. Nuclear engineering has been in the forefront of the development and application of this method. In the Safety Study on US Power Plants published in 1975 the risk of an entire technology was investigated systematically and quantified for the first time. Meanwhile the methods have continuously been improved and applied to a number of nuclear power stations."
