This book uses the metaphor "The economy is society's metabolism" as a springboard to develop a rigorous theoretical framework for a better system of national accounts which goes "Beyond GDP" and is relevant to the age of resource depletion. Society is entering a new era in which biophysical limits related to natural resource extraction rates and the biosphere's waste assimilation capacity are becoming binding constraints on mature economies. Unfortunately, the data needed for policy-makers to understand and manage economic growth in this new era are not universally available. All stakeholders need a new way to understand our economy in the context of the biosphere's ability to provide essential natural capital, and we suggest that detailed information about materials, energy, embodied energy, and energy intensity should be routinely gathered, analyzed, and disseminated from a centralized location to provide markets and policymakers with a more comprehensive understanding of the biophysical economy. However, a firm theoretical foundation is needed before proceeding along this new path, which this book is intended to provide. After arguing that the stock of manufactured capital is an important driver of material and energy demands imposed upon the biosphere, a new accounting framework is derived from the laws of thermodynamics to reflect the fact that material and embodied energy accumulate within the capital stock of economic sectors. This framework extends the Energy Input-Output (EI-O) techniques first developed by Bullard, Herendeen, and others to estimate energy intensity of economic products. Implications from the new framework are discussed, including the value of economic metrics for policy-making, the need for physically-based rather than product-based EI-O formulations, a re-assessment of the concept of economic "growth," and an evaluation of recycling, reuse, and dematerialization. The framework also provides an opportunity to assess an array of definitions for Daly's "steady-state economy" in relation to the ideal of a sustainable economy. The book ends with a list of steps to be taken in creating a more comprehensive system of national accounts: National accounting agencies worldwide should develop and maintain balance sheets of both natural and manufactured capital in addition to national income statements All stocks and inter-sector flows should be provided in physical as well as financial units In the US, the Bureau for Economic Analysis (BEA) should restart detailed Capital, Labor, Energy, Material, and Services (KLEMS) reporting National accounting agencies should routinely estimate the energy intensity of economic products, and all of the above should be estimated and disseminated on an annual basis.

Nowadays information technology is based on semiconductor and ferromagnetic materials. Information processing and computation are based on electron charge in semiconductor transistors and integrated circuits, and information is stored on magnetic high-density hard disks based on the physics of the electron spins. Recently, a new branch of physics and nanotechnology, called magneto-electronics, spintronics, or spin electronics, has emerged, which aims at simultaneously exploiting both the charge and the spin of electrons in the same device. A broader goal is to develop new functionality that does not exist separately in a ferromagnet or a semiconductor. The aim of this book is to present new directions in the development of spin electronics in both the basic physics and the technology which will become the foundation of future electronics.
Atmospheric ice takes a wide range of fascinating forms, all beautiful in their own ways but many posing severe risk to the security of overhead networks for electric power, communications and other systems. This comprehensive book documents the fundamentals of atmospheric icing and surveys the state of the art in eight chapters, each written by a team of experienced and internationally renowned experts. The treatment is detailed and richly illustrated. The presentation follows a logical sequence, starting with the icing climate and meteorological conditions, proceeding through development of observations and models of accretion and release of ice and heavy snow, then considering static and dynamic mechanical loads, the effects of ice and snow on electrical insulation, de-icing, ice prevention and mitigation methods. The statistical analysis of icing data and the mathematical and numerical modelling support appropriate mechanical and electrical design processes for icing conditions on overhead lines. Technical specialists, researchers and students in engineering and environmental science will all find value throughout the text.
Successfully classroom-tested at the graduate level, Linear Control Theory: Structure, Robustness, and Optimization covers three major areas of control engineering (PID control, robust control, and optimal control). It provides balanced coverage of elegant mathematical theory and useful engineering-oriented results. The first part of the book develops results relating to the design of PID and first-order controllers for continuous and discrete-time linear systems with possible delays. The second section deals with the robust stability and performance of systems under parametric and unstructured uncertainty. This section describes several elegant and sharp results, such as Kharitonov's theorem and its extensions, the edge theorem, and the mapping theorem. Focusing on the optimal control of linear systems, the third part discusses the standard theories of the linear quadratic regulator, Hinfinity and l1 optimal control, and associated results. Written by recognized leaders in the field, this book explains how control theory can be applied to the design of real-world systems. It shows that the techniques of three term controllers, along with the results on robust and optimal control, are invaluable to developing and solving research problems in many areas of engineering.

A major barrier to the introduction of ferroelectric devices into mass markets remains their limited reliability due to fatigue. The underlying physical and chemical mechanisms of this material fatigue phenomenon are extremely complex, and the relevant influences range from single-point defects to macroscopic boundary conditions. This book summarizes the different aspects of fatigue in ferroelectrics. It is primarily concerned with bulk material effects. Mechanical, electrical, and physico-chemical processes are described; reference data are given for different loading regimes and boundary conditions; and various fatigue models are compared. The monograph also demonstrates how the results of acoustic emission and of microscopy studies reveal the microscopic origins of fatigue in ferroelectric devices.

This book showcases the strengths of Linear Programming models for Cyber Physical Systems (CPS), such as the Smart Grids. Cyber-Physical Systems (CPS) consist of computational components interconnected by computer networks that monitor and control switched physical entities interconnected by physical infrastructures. A fundamental challenge in the design and analysis of CPS is the lack of understanding in formulating constraints for complex networks. We address this challenge by employing collection of Linear programming solvers that models the constraints of sub-systems and micro grids in a distributed fashion. The book can be treated as a useful resource to adaptively schedule resource transfers between nodes in a smart power grid. In addition, the feasibility conditions and constraints outlined in the book will enable in reaching optimal values that can help maintain the stability of both the computer network and the physical systems. It details the collection of optimization methods that are reliable for electric-utilities to use for resource scheduling, and optimizing their existing systems or sub-systems. The authors answer to key questions on ways to optimally allocate resources during outages, and contingency cases (e.g., line failures, and/or circuit breaker failures), how to design de-centralized methods for carrying out tasks using decomposition models; and how to quantify un-certainty and make decisions in the event of grid failures.
In this book, modeling and control design of electric motors, namely step motors, brushless DC motors and induction motors, are considered. The book focuses on recent advances on feedback control designs for various types of electric motors, with a slight emphasis on stepper motors. For this purpose, the authors explore modeling of these devices to the extent needed to provide a high-performance controller, but at the same time one amenable to model-based nonlinear designs. The control designs focus primarily on recent robust adaptive nonlinear controllers to attain high performance. It is shown that the adaptive robust nonlinear controller on its own achieves reasonably good performance without requiring the exact knowledge of motor parameters. While carefully tuned classical controllers often achieve required performance in many applications, it is hoped that the advocated robust and adaptive designs will lead to standard universal controllers with minimal need for fine tuning of control parameters.
The International Workshop on Embedded Systems -- Modeling, Technology, and Applications is the seventh in a successful series of workshops that were established by Shanghai Jiao Tong University and Technische Universitat Berlin. The goal of those workshops is to bring together researchers from both universities in order to present research results to an international community. Successfully realizing Embedded Systems requires methods and tools from different disciplines. Formal specification techniques not only for the embedded system itself but also for the device and environment that is controlled by the embedded system are used for functional and non-functional properties (e.g. performance, real-time behavior). Formal models allow analyzing and optimizing those properties. Different methods and tools are used to design the required behavior of the system and finally to implement and test the system."

Currently employed at STMicroelectronics, Transactional-Level Modeling (TLM) puts forward a novel SoC design methodology beyond RTL with measured improvements of productivity and first time silicon success. The SystemC consortium has published the official TLM development kit in May 2005 to standardize this modeling technique. The library is flexible enough to model components and systems at many different levels of abstractions: from cycle-accurate to untimed models, and from bit-true behavior to floating-point algorithms. However, careful selection of the abstraction level and associated methodology is crucial to ensure practical gains for design teams. Transaction-Level Modeling with SystemC presents the formalized abstraction and related methodology defined at STMicroelectronics, and covers all major topics related to the Electronic System-Level (ESL) industry: - TLM modeling concepts Complementary to the book, open source code to put this approach into practice is available on several Internet sites as indicated in the first chapter.

High-frequency switching power semiconductor devices are at the heart of power electronic converters. To date, these devices have been dominated by the well-established silicon (Si) technology. However, their intrinsic physical limits are becoming a barrier to achieving higher performance power conversion. Wide Bandgap (WBG) semiconductor devices offer the potential for higher efficiency, smaller size, lighter weight, and/or longer lifetime. Applications in power grid electronics as well as in electromobility are on the rise, but a number of technological bottle-necks need to be overcome if applications are to become more widespread - particularly packaging. This book describes the development of advanced multi-chip packaging solutions for novel WBG semiconductors, specifically silicon carbide (SiC) power MOSFETs. Coverage includes an introduction; multi-chip power modules; module design and transfer to SiC technology; electrothermal, thermo-mechanical, statistical and electromagnetic aspects of optimum module design; high temperature capable SiC power modules; validation technologies; degradation monitoring; and emerging packaging technologies. The book is a valuable reference for researchers and experts in academia and industry.
