These advances have impacted microelectronics, sensors, materials science, and corrosion science, generating new fields of research that promote interaction between biology, medicine, and microelectronics. This volume reviews nanotechnology applications in selected high technology areas with particular emphasis on advances in such areas. Chapters are classified under four different headings: Nanotechnology for energy devices - Nanotechnology for magnetic storage devices - Nanotechnology for bio-chip applications - Nanotechnology for MEMS/Packaging.

This book presents techniques for energy reduction in adaptive embedded multimedia systems, based on dynamically reconfigurable processors. The approach described will enable designers to meet performance/area constraints, while minimizing video quality degradation, under various, run-time scenarios. Emphasis is placed on implementing power/energy reduction at various abstraction levels. To enable this, novel techniques for adaptive energy management at both processor architecture and application architecture levels are presented, such that both hardware and software adapt together, minimizing overall energy consumption under unpredictable, design-/compile-time scenarios.

Managing a successful transition of the current energy supply system to less carbon emitting options, ensuring a safe and secure supply during the whole process and in the long term, is one of the largest challenges of our time. Various approaches and first implementations show that it is not only technological issue, but also a matter of societal acceptance and acceptability, considering basic ethic values of the society. The main foci of the book are, thus, to develop an understanding about the specific challenges of the scientific policy advice in the area, to explore typical current approaches for the analysis of future energy systems and to develop criteria for the quality assessment and guidelines for the improvement of such studies. The book provides assistance to the interpretation of existing studies and guidelines for setting up and carrying out new analyses as well as for communicating and applying the results. Thereby, it aims to support the involved actors such as the respective scientific experts and researchers as well as decision makers, energy suppliers, stakeholders and the interested public in designing procedures for a successful transition process. The study elaborates consistent interdisciplinary advice as contribution for realising a continuously safe and secure, long-term viable energy supply in spite of diverse interests, multi-level responsibilities, multi-dimensional processes, large uncertainties and lack of knowledge about future developments.

Energy exchange is a major foundation of the dynamics of physical systems, and, hence, in the study of complex multi-domain systems, methodologies that explicitly describe the topology of energy exchanges are instrumental in structuring the modeling and the computation of the system's dynamics and its control. This book is the outcome of the European Project "Geoplex" (FP5 IST-2001-34166) that studied and extended such system modeling and control methodologies. This unique book starts from the basic concept of port-based modeling, and extends it to port-Hamiltonian systems. This generic paradigm is applied to various physical domains, showing its power and unifying flexibility for real multi-domain systems.

The production and consumption of energy carriers in complex buildings take place within the network of interconnected energy processes. For this reason, a change carried out in one energy process influences other energy processes. Therefore, all balance equations of energy carriers should be investigated as a whole, and energy management of complex buildings creates a large energy system with internal relationships between energy installations and the equipment, as well as external relationships with the environment. Energy Systems of Complex Buildings presents the system approach to the energy-ecological analysis of energy management in complex buildings. Mathematical models of balancing the direct energy consumption, as well as cumulative energy consumption and cumulative emission of noxious substances are based on input-output analysis. Algorithms devoted to system analysis in the exploitation of energy management of complex buildings are included. In the case of ecological analysis, a new approach is presented basing on the idea of thermoecological costs. In this way, two groups of noxious influence (depletion of non-renewable energy resources and emissions of noxious substances) are taken into account. The LCA energy-ecological analysis of complex buildings has also been presented. Students, building designers, energy auditors, and researchers will learn the methodology of evaluating the energy and ecological effects by applying new technologies and devices in buildings, which influence future investigations concerning the energy and ecological analysis of complex buildings.

With energy consumption set to become one of the biggest issues in the daily lives of householders around the world, this book could not be more relevant - despite the fact that it focuses on India. Pachauri adopts a socio-economic approach to analyzing the energy system and energy consumption in India from a household perspective. The work also incorporates two crucial aspects often ignored: namely, the importance of non-commercial sources of energy, and diversity in the patterns of energy usage.

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.

This book lies at the intersection of natural sciences, economics, and water en- neering and is in line with the long tradition of environmental economics at the University of Heidelberg. In the 1970s, the Neo-Austrian Capital Theory was developed using the fundamental laws of thermodynamics as a common language between the natural and social sciences. Niemes (1981) integrated the dynamic and irreversibility characteristics of the natural environment into the Neo-Austrian c- ital theory. Faber et al. (1983, 1987, 1995) then extended this interdisciplinary approach further to create a comprehensive, dynamic, environmental resource model. Over the last 3 decades, the theoretical foundations of environmental economics have been modi ed and there have been an impressive variety of applications. This book aims to reduce the gaps between economic theory, natural sciences, and engineering practice. One of the reasons these gaps exist is because economic assumptions are used to construct dynamic environmental and resource models, which are not consistent with the fundamental laws of the natural sciences. Another reason for the gap might be the distance between academic theory and real world situations. Based on an extended thermodynamic approach, the authors explain which economic assumptions are acceptable for constructing a dynamic model that is consistent with the natural sciences. In particular, the special role of water in the production and reproduction activities will be considered as an integral component.

This book explores a novel technique for processing biodiesel using lipase immobilization by encapsulation and its physical properties, stability characteristics, and application in stirred tank and re-circulated packed bed immobilized reactors for biodiesel production. The enzymatic processing of biodiesel addresses many of the problems associated with chemical processing. It requires only moderate operating conditions and yields a high-quality product with a high level of conversion and the life cycle assessment of enzymatic biodiesel production has more favourable environmental consequences. The chemical processing problems of waste water treatment are lessened and soap formation is not an issue, meaning that waste oil with higher FFA can be used as the feedstock. The by product glycerol does not require any purification and it can be sold at higher price. However, soluble enzymatic processing is not perfect. It is costly, the enzyme cannot be recycled and its removal from the product is difficult. For these reasons, immobilized enzymatic process has been developed which retains the advantages of the soluble enzymatic process and reuse of the enzyme is possible which decreases the enzyme cost, the biodiesel produced does not contain any enzyme residue and the activity of the enzyme can be increased by immobilization. The drawbacks of the immobilized enzyme process are mass transfer limitation, enzyme leakage, the lack of a versatile commercial immobilized enzyme and some of immobilization methods involve toxic chemicals. To overcome the drawbacks of the immobilized enzyme, an attempt is made to use a degradable biopolymer ( -carrageenan) as a carrier for lipase immobilization.

Human-kind and ecological systems are currently facing one of the toughest challenges: how to feed more billions of people in the future within the perspective of climate change, energy shortages, economic crises and growing competition for the use of renewable and non renewable resources. This challenge is even more crucial given that we have not yet come close to achieving the Millennium Development Goal of halving the number of people living in extreme poverty and hunger. Scientists and relevant stakeholders are now voicing a clear message: that multiple challenges the world is facing require innovative, multifaceted, science-based, technological, economic and political approaches in theoretical thinking, decision making and action. With this background central to survival and well-being, the purpose of this volume is to formulate and promote relevant theoretical analysis and policy recommendations. The major perspective of this publication is that paradigm and policy shifts at all levels are needed urgently. This is based on the evidence that agriculture in the 21st century will be undergoing significant demands, arising largely from the need to increase the global food enterprise, while adjusting and contributing to climate change adaptation and mitigation. Global Food Insecurity aims at providing structure to effect achievement of this critically needed roadmap.

Around the world, liberalization and privatization in the electricity industry have lead to increased competition among utilities. At the same time, utilities are now exposed more than ever to risk and uncertainties, which they cannot pass on to their customers through price increases as in a regulated environment. Especially electricity-generating companies have to face volatile wholesale prices, fuel price uncertainty, limited long-term hedging possibilities and huge, to a large extent, sunk investments.

In this context, Uncertainty in the Electric Power Industry: Methods and Models for Decision Support aims at an integrative view on the decision problems that power companies have to tackle. It systematically examines the uncertainties power companies are facing and develops models to describe them - including an innovative approach combining fundamental and finance models for price modeling. The optimization of generation and trading portfolios under uncertainty is discussed with particular focus on CHP and is linked to risk management. Here the concept of integral earnings at risk is developed to provide a theoretically sound combination of value at risk and profit at risk approaches, adapted to real market structures and market liquidity. Also methods for supporting long-term investment decisions are presented: technology assessment based on experience curves and operation simulation for fuel cells and a real options approach with endogenous electricity prices.

The book gives an outline of prevailing hydrogeologic conditions in the Arab Middle East together with the geologic background. Emphasis is given to relationships between the main features influencing the hydrogeologic conditions - regional geologic developments, paleogeographic conditions, morphology, climate and paleo-climate - and the resulting hydrogeologic features: formation of aquifers, distribution of major aquifers, main groundwater flow systems, occurrence of renewable and fossil groundwater. Reported data on hydraulic aquifer parameters, recharge rates and groundwater flow volumes are evaluated with a view to arrive at characteristic values under the specific hydrogeologic and climatic conditions. The area considered covers approximately the Arabian Plate. Information on the following countries is included: Bahrain, Iraq, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, Syria, United Arab Emirates, West Bank and Gaza, Yemen.

Dynamics is a science concerned with movement and changes. In the most general approach it relates to life processes as well as behavior in nature in rest. It governs small particles, technical objects, conversion of matter and materials but also concerns people, groups of people in their individual and, in particular, social dimension. In dynamics we always have to do with causes or stimuli for motion, the rules of reaction or behavior and its result in the form of trajectory of changes. This book is devoted to dynamics of a wide class of specific but very important objects such as electromechanical systems. This is a very rigorous discipline and has a long tradition, as its theoretical bases were formulated in the first half of the XIX century by d' Alembert, Lagrange, Hamilton, Maxwell and other prominent scientists, but their crucial results were based on previous pioneering research of others such as Copernicus, Galileo, Newton... This book in its theoretical foundations is based on the principle of least action which governs classical as well as relativistic mechanics and electromagnetism and leads to Lagrange's equations which are applied in the book as universal method to construct equations of motion of electromechanical systems. It gives common and coherent grounds to formulate mathematical models for all lumped parameters' electromechanical systems, which are vital in our contemporary industry and civilized everyday life. From these remarks it seems that the book is general and theoretical but in fact it is a very practical one concerning modern electrical drives in a broad sense, including electromechanical energy conversion, induction motor drives, brushless DC drives with a permanent magnet excitation and switched reluctance machines (SRM). And of course their control, which means shaping of their trajectories of motion using modern tools, their designed autonomy in keeping a track according to our programmed expectations. The problems presented in the book are widely illustrated by characteristics, trajectories, dynamic courses all computed by use of developed simulation models throughout the book. There are some classical subjects and the history of the discipline is discussed but finally all modern tools and means are presented and applied. More detailed descriptions follow in abstracts for the particular chapters. The author hopes kind readers will enjoy and profit from reading this book.

Human history has often been described as a progressive relinquishment from environmental constraints. Now, it seems, we have come full circle. The ecological irrationalities associated with industrial societies have a lengthy history, and our purpose in the proposed book is not to catalogue this litany of wrongs. Rather, this book is about political responses to global environmental crisis at a crucial turning point in history, by focusing on the political discourses surrounding the tar sands in Alberta, Canada.

The aim of this book is to explore science and technology from the viewpoint of creating new knowledge, as opposed to the reinterpretation of existing knowledge in ever greater but uncertain detail. Scientists and technologists make progress by distinguishing between what they regard as meaningful and what they consider as secondary or unimportant. The meaningful is dynamic; typically, the less important is static. Science and technology have made a major contribution to the culture and to the standard of living of our society. From antiquity to the present day, the most distinguished scientists and technologists have been thinkers, experimenters and persons willing and able to challenge "the obvious". Technology develops products and processes based on the breakthroughs of science. If technologists fail to steadily upgrade their skills, tools and methods, they will only be as good as their last design, risking obsolescence. Using practical examples and case studies, this book documents the correlations existing between science and technology, and elucidates these correlations with practical applications ranging from real-life situations, from R&D to energy production. As it is a salient problem, and a most challenging one to our society, power production has been chosen as a major case study. The holistic approach to science and technology followed by this text enhances the ability to deliver practical results. This book is intended for students and researchers of science, technology and mathematical analysis, while also providing a valuable reference book for professionals. Its subject is one of the most debated problems of mankind.

This book assesses how low-carbon generation, the advance of energy storage and consumer-based models can help decarbonise electricity supplies at a national level. This book is built around developing a decarbonised electricity mix for Britain which reduces fossil fuels from 50% of supply in 2018 down to levels within 2030 carbon targets. Crossland explores the idea of a future energy storage mix which blends domestic batteries, vehicles, thermal stores and pumped hydro to provide a flexible, responsive electricity system. He then goes on to look at how much storage can contribute to decarbonisation in a multitude of contexts - from domestic to national electricity. This book also discusses how efficiency and self-sufficiency can bring about a decarbonised electricity use within our homes today. Britain is used as the main example, but the themes and conclusions are applicable to a global audience, and each chapter draws on practical case studies from around the world to illustrate key ideas. Drawing on the author's experience in delivering and analysing low-carbon energy projects in the UK, Sub-Saharan Africa, Latin America and Oceania, this book will be of great relevance to students, scholars and industry specialists with an interest in energy technology, policy and storage.
