Download or read book Measuring Current Voltage and Power written by K. Iwansson and published by Elsevier. This book was released on 1999-06-01 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative new book focuses on recent developments in the instrumentation for sending voltages and currents. It covers new trends and challenges in the field, such as measurements of biocurrents, the increased speed of the components for data taking, testing of computers and integrated circuits where the measurement of rapid voltage and current variations on a very small geometrical scale is necessary. The first chapter concentrates on recent methods to sense voltages and currents, while the rest of the book investigates the applied side, covering for instance electrical power and energy measurements. The main purpose of this volume is to illustrate commonly employed techniques rather than track the scientific evolution and merits and therefore mainly covers patent literature aimed at industrial applications. It is an exciting addition, justifying the series' claim to cover state-of-the-art developments in both the applied and theoretical fields of sensors and actuators. The measurement of voltages and currents is a common task in the field of electricity and electronics. From a technical point of view it is useful to identify schematically different steps of such a measurement. In a first step a voltage or a current is sensed, intermediate steps such as amplification, transmission and further treatment may follow to yield the result in the final step. Today in most cases microprocessors perform the final steps of such measurements. Analog-to digital converters digitise a voltage that is proportional to the value to be measured and a processor performs further computations and handles the storage and the display of the results. The prerequisite for such measurements are sensors or transducers that respond in a known way to the voltage or current to be measured. The emphasis of this book is put on recent developments of the instrumentation for sensing voltages and currents. Aside from the general trend towards smaller, cheaper and more reliable instrumentation, new demands have arisen. New applications, like measurements of biocurrents, ask for higher sensitivities. Computers and integrated circuits pose new challenges. To exploit the increased speed of the components for data taking, suitable sensors are required. The accuracy that can be achieved depends more than ever on the first step, the acquisition of the raw data. The influence of the measurement process on the results becomes more crucial. Testing of integrated circuits themselves is a completely new application. For such tests one has to measure rapid voltage and current variations on very small geometrical scales. Here, as well as in the traditional high voltage applications, contactless measurements play an important role. The organisation of this book is as follows: In the first chapter different methods to sense voltages and currents are described. For the sake of completeness most commonly used methods are mentioned, we concentrate, however, on those developed recently. The chapters address the subject from the side of different applications in which voltages and currents are sensed. Since the main purpose of this publication is to illustrate commonly employed techniques rather than to track the scientific evolution and merits in particular fields, in general those publications that illustrate a particular measurement principle best have been cited. The citation of a particular reference does therefore not imply that this is the first or most pertinent publication in the respective field.

Download or read book Measuring Energy Security written by Mr.Prakash Loungani and published by International Monetary Fund. This book was released on 2011-02-01 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present evidence on one facet of energy security in OECD economies - the extent of diversification in sources of oil and natural gas supplies. Viewed from the perspective of the energy-importing countries as a whole, there has not been much change in diversification in oil supplies over the last decade, but diversification in sources of natural gas supplies has increased steadily. We document the cross-country heterogeneity in the extent of diversification. We also show how the extent of diversification changes if account is taken of the political risk attached to suppliers; the size of the importing country; and transportation risk.

Download or read book ICT Energy Concepts for Energy Efficiency and Sustainability written by Giorgos Fagas and published by BoD – Books on Demand. This book was released on 2017-03-22 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a previous volume (ICT-Energy-Concepts Towards Zero-Power ICT; referenced below as Vol. 1), we addressed some of the fundamentals related to bridging the gap between the amount of energy required to operate portable/mobile ICT systems and the amount of energy available from ambient sources. The only viable solution appears to be to attack the gap from both sides, i.e. to reduce the amount of energy dissipated during computation and to improve the efficiency in energy-harvesting technologies. In this book, we build on those concepts and continue the discussion on energy efficiency and sustainability by addressing the minimisation of energy consumption at different levels across the ICT system stack, from hardware to software, as well as discussing energy consumption issues in high-performance computing (HPC), data centres and communication in sensor networks. This book was realised thanks to the contribution of the project ‘Coordinating Research Efforts of the ICT-Energy Community’ funded from the European Union under the Future and Emerging Technologies (FET) area of the Seventh Framework Programme for Research and Technological Development (grant agreement n. 611004).

Download or read book Measuring the Benefits of Energy Access written by Douglas F. Barnes and published by Inter-American Development Bank. This book was released on 2018-12-10 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Impact evaluation has gained recognition over the last decade as an essential component of project development. Impact evaluation details how and to what extent policies and project interventions contribute to socioeconomic welfare gains or losses for society. Such evaluations are also important for identifying key lessons for future policies and investments. In the case of modern energy access, the measurement of costs is fairly straightforward. However, measuring the benefits to society is more difficult and might involve implementing national or regional surveys. Past efforts have often underestimated the complex linkages of benefits produced by programs involved in providing electricity and clean cooking energy to rural and other populations without access to modern energy services. Thus, it has often been difficult to balance the costs of program investments in energy access vis-à-vis their benefits. This study’s main objective is to develop a practical method by which to measure the benefits of rural energy, including both electricity and clean cooking. The methods reviewed in this report involve both formal and informal techniques of data collection, including quantitative and qualitative methods of analysis. The research pays attention to such concepts as quality of life, effects on education, and other key components of social development; that is, it tackles those benefits of modern energy access that traditionally have been difficult to measure, as well as the easier-to-measure benefits.

Available in PDF, EPUB and Kindle. Book excerpt: This book, written for the benefit of engineering students and practicing engineers alike, is the culmination of the author's four decades of experience related to the subject of electrical measurements, comprising nearly 30 years of experimental research and more than 15 years of teaching at several engineering institutions. The unique feature of this book, apart from covering the syllabi of various universities, is the style of presentation of all important aspects and features of electrical measurements, with neatly and clearly drawn figures, diagrams and colour and b/w photos that illustrate details of instruments among other things, making the text easy to follow and comprehend. Enhancing the chapters are interspersed explanatory comments and, where necessary, footnotes to help better understanding of the chapter contents. Also, each chapter begins with a "recall" to link the subject matter with the related science or phenomenon and fundamental background. The first few chapters of the book comprise "Units, Dimensions and Standards"; "Electricity, Magnetism and Electromagnetism" and "Network Analysis". These topics form the basics of electrical measurements and provide a better understanding of the main topics discussed in later chapters. The last two chapters represent valuable assets of the book, and relate to (a) "Magnetic Measurements", describing many unique features not easily available elsewhere, a good study of which is essential for the design and development of most electric equipment – from motors to transformers and alternators, and (b) "Measurement of Non-electrical Quantities", dealing extensively with the measuring techniques of a number of variables that constitute an important requirement of engineering measurement practices. The book is supplemented by ten appendices covering various aspects dealing with the art and science of electrical measurement and of relevance to some of the topics in main chapters. Other useful features of the book include an elaborate chapter-by-chapter list of symbols, worked examples, exercises and quiz questions at the end of each chapter, and extensive authors' and subject index. This book will be of interest to all students taking courses in electrical measurements as a part of a B.Tech. in electrical engineering. Professionals in the field of electrical engineering will also find the book of use.

Download or read book Home Energy Information written by David C. Green and published by Springer. This book was released on 2014-11-17 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book contains the data required to measure and manage energy consumption in residential buildings. This book describes energy information in detail so that any homeowner can measure energy use on a continuing basis, make decisions regarding how to conserve energy, implement improvements, then monitor the results of those improvements. In the past, it has been difficult to collect residential energy consumption data in real-time. This book helps overcome that challenge by teaching readers how to use self-installed data collection devices that monitor consumption of circuits or appliances, along with freely available information to benchmark against other homes in the area. It demonstrates how information derived from many sources, such as the kWh listed on an electric bill, can be combined into simple calculations that illuminate how well conservation efforts are working from day to day, month to month, or year to year. Homeowners have ultimate control over the decision making process required to realize energy savings. This book simplifies the tasks of collecting, calculating and reporting energy information to the homeowner, putting the power to conserve energy in the hands of the people who will ultimately benefit the most directly from conservation efforts.

Available in PDF, EPUB and Kindle. Book excerpt: "Carolyn and Annika bring decades of expertise in the care of patients with Anorexia, Bulimia, Binge Eating Disorder, and the many related atypical and subsyndromal variants. Their clinical wisdom, understanding of the experience of sufferers and those who love them, and understanding of these illnesses and the recovery process infuse these pages." -Diane Mickley, MD, Director, Wilkins Center for Eating Disorders The ever changing field of eating disorder treatment needs innovative new techniques and approaches. As the number of people with these challenging disorders increases at an alarming rate, treatment has not kept pace. The death rate for Anorexia Nervosa in the U.S. is twelve times higher than all other leading causes of death combined for the 15-to-24 age group. Measuring Health from the Inside is a major step forward in treating patients with eating disorders. This important book explains how two simple measurement techniques-Metabolic Testing and Body Composition Analysis-can help patients make rapid progress in understanding their condition and tracking their progress toward recovery. Thousands of patients have been successfully diagnosed and treated by this technology at Carolyn's clinic and Annika's private practice. In Measuring Health from the Inside, they explain how the information from the tests can be used to help treat patients not only for their underlying eating disorder but also for the malnutrition that almost always accompanies-and worsens-the condition. Based on their extensive experience, they offer practical guidance for therapists, patients, and loved ones on the often overlooked importance of nutrition in treating eating disorders.

Download or read book Export Product Quality Renewable Energy and Sustainable Production written by Umer Shahzad and published by Frontiers Media SA. This book was released on 2023-09-12 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Economic development has long been acknowledged for its beneficial effects on human well-being. In the context of economic globalization and vertical specialization, increasing the quality of export products is more critical and necessary to export success and sustainable development. The product's quality is inextricably linked to its manufacture and production, which need various types of energy and raw materials. Meanwhile, the adoption of more environmentally friendly and cleaner energy sources contributes to the achievement of sustainable production. Therefore, product quality may provide a new perspective from which to investigate the systematic relationship between greener and renewable energy sources, sustainable production and environmental regulations, as well as the nature of export competitiveness. Generally, export product quality has referred to the quality of manufactured products within the product lines. Quality refers to the relative price of a country's varieties within their respective product lines. Product sophistication assesses the composition of the aggregate exports. Different varieties of same product as per quality level are being produced by several developing and emerging economies. Within any given product line, quality converges both conditionally and unconditionally to the world's benchmark; increases in institutional quality and human capital are associated with faster quality upgrading. In turn, faster growth in quality is associated with more rapid output growth.
