Gianni Conte, Dante Del Corso
R4,326 Discovery Miles 43 260 Ships in 12 - 17 working days

The continous development of computer technology supported by the VLSI revolution stimulated the research in the field .of multiprocessors systems. The main motivation for the migration of design efforts from conventional architectures towards multiprocessor ones is the possibi I ity to obtain a significant processing power together with the improvement of price/performance, reliability and flexibility figures. Currently, such systems are moving from research laboratories to real field appl ications. Future technological advances and new generations of components are I ikely to further enhance this trend. This book is intended to provide basic concepts and design methodologies for engineers and researchers involved in the development of mul tiprocessor systems and/or of appl ications based on multiprocessor architectures. In addition the book can be a source of material for computer architecture courses at graduate level. A preliminary knowledge of computer architecture and logical design has been assumed in wri ting this book. Not all the problems related with the development of multiprocessor systems are addressed in th i s book. The covered range spans from the electrical and logical design problems, to architectural issues, to design methodologis for system software. Subj ects such as software development in a multiprocessor environment or loosely coupled multiprocessor systems are out of the scope of the book. Since the basic elements, processors and memories, are now available as standard integrated circuits, the key design problem is how to put them together in an efficient and reliable way."

The re-engineering of power transmission systems is crucial to meeting the objectives of such regulators as the European Union. In addition to its market, organisational and regulatory aspects, this re-engineering will also involve technical issues dealing with the progressive integration of innovative transmission technologies in the daily operation of transmission system operators. In this context, Advanced Technologies for Future Transmission Grids provides an overview of the most promising technologies, likely to be of help to planners of transmission grids in responding to the challenges of the future: security of supply; integration of renewable generation; and creation of integrated energy markets (using the European case as an example). These issues have increased importance because of administrative complication and the fragmentation of public opinion expressed on the build up of new infrastructure. For each technology discussed, the focus is on the technical-economic perspective rather than on purely technological points of view. A transmission-system-operator-targeted Technology Roadmap is presented for the integration of promising innovative power transmission technologies within power systems of the mid-long term. Although the primary focus of this text is in the sphere of the European energy market, the lessons learned can be generalized to the energy markets of other regions.

R2,692 Discovery Miles 26 920 Ships in 10 - 15 working days

Major changes have occurred in both the composition of energy supply and the choice of technology, especially in activities in which energy intensity has a significant bearing on the costs and competitiveness of goods and services. Presented here, in the context of these changes, are case studies on the macroeconomic evaluation of ethylalcohol programs and the microeconomic evaluation of technologies for irrigation pumping. "Environment and Resource Conservation"

During the last decade, a large volume of literature has addressed the two major policy issues concerning energy programs in developing countries: overall energy conservation and provision of energy for rural development needs. Yet, many of these works have been supply-sided without adequate analysis of users' needs and the different option to meet them. Ex-post evaluations of existing field experiences with renewable technologies are still scarce, and many of those which have appeared provide limited insights for planning and implementation in different countries. Socioeconomic Aspects of Renewable Energy Technologies addresses these oversights. A selected number of technologies and topics concerning renewable energy sources for developing countries are discussed, including ethanol and the macro-economic evaluation of ethanol programs; various renewable energy technologies for end-use such was water-pumping for irrigation; and the micro-economic evaluation of these additional technologies.

R2,842 Discovery Miles 28 420 Ships in 10 - 15 working days

Fault-tolerance in integrated circuits is not an exclusive concern regarding space designers or highly-reliable application engineers. Rather, designers of next generation products must cope with reduced margin noises due to technological advances. The continuous evolution of the fabrication technology process of semiconductor components, in terms of transistor geometry shrinking, power supply, speed, and logic density, has significantly reduced the reliability of very deep submicron integrated circuits, in face of the various internal and external sources of noise. The very popular Field Programmable Gate Arrays, customizable by SRAM cells, are a consequence of the integrated circuit evolution with millions of memory cells to implement the logic, embedded memories, routing, and more recently with embedded microprocessors cores. These re-programmable systems-on-chip platforms must be fault-tolerant to cope with present days requirements. This book discusses fault-tolerance techniques for SRAM-based Field Programmable Gate Arrays (FPGAs). It starts by showing the model of the problem and the upset effects in the programmable architecture. to protect integrated circuits against errors. A large set of methods for designing fault tolerance systems in SRAM-based FPGAs is described. Some presented techniques are based on developing a new fault-tolerant architecture with new robustness FPGA elements. Other techniques are based on protecting the high-level hardware description before the synthesis in the FPGA. The reader has the flexibility of choosing the most suitable fault-tolerance technique for its project and to compare a set of fault tolerant techniques for programmable logic applications.

R3,939 Discovery Miles 39 390 Ships in 12 - 17 working days

This book consists of the identification, characterization, and modeling of electromagnetic interferences in substations for the deployment of wireless sensor networks. The authors present in chapter 3 the measurement setup to record sequences of impulsive noise samples in the ISM band of interest. The setup can measure substation impulsive noise, in wide band, with enough samples per time window and enough precision to allow a statistical study of the noise. During the measurement campaign, the authors recorded around 120 noise sequences in different substations and for four ranges of equipment voltage, which are 25 kV, 230 kV, 315 kV and 735 kV. A characterization process is proposed, by which physical characteristics of partial discharge can be measured in terms of first- and second-order statistics. From the measurement campaign, the authors infer the characteristics of substation impulsive noise as a function of the substation equipment voltage, and can provide representative parameters for the four voltage ranges and for several existing impulsive noise models. The authors investigate in chapters 4 and 5 the modeling of electromagnetic interferences caused by partial discharge sources. First, the authors propose a complete and coherent approach model that links physical characteristics of high-voltage installations to the induced radio-interference spectra of partial discharge sources. The goodness-of-fit of the proposed physical model has been measured based on some interesting statistical metrics. This allows one to assess the effectiveness of the authors' approach in terms of first- and second-order statistics. Chapter 6 proposes a model based on statistical approach. Indeed, substation impulsive noise is composed of correlated impulses, which would require models with memory in order to replicate a similar correlation. Among different models, we have configured a Partitioned Markov Chain (PMC) with 19 states (one state for the background noise and 18 states for the impulse); this Markov-Gaussian model is able to generate impulsive noise with correlated impulse samples. The correlation is observable on the impulse duration and the power spectrum of the impulses. Our PMC model provides characteristics that are more similar to the characteristics of substation impulsive noise in comparison with other models, in terms of time and frequency response, as well as Probability Density Functions (PDF). Although PMC represents reliably substation impulsive noise, the model remains complex in terms of parameter estimation due to a large number of Markov states, which can be an obstacle for future wireless system design. In order to simplify the model, the authors decrease the number of states to 7 by assigning one state to the background noise and 6 states to the impulse and we call this model PMC-6. PMC-6 can generate realistic impulses and can be easily implemented in a receiver in order to mitigate substation impulsive noise. Representative parameters are provided in order to replicate substation impulsive noise for different voltage ranges (25-735 kV). Chapter 7, a generalized radio-noise model for substations is proposed, in which there are many discharges sources that are randomly distributed over space and time according to the Poisson field of interferers approach. This allows for the identification of some interesting statistical properties of moments, cumulants and probability distributions. These can, in turn, be utilized in signal processing algorithms for rapid partial discharge's identification, localization, and impulsive noise mitigation techniques in wireless communications in substations. The primary audience for this book is the electrical and power engineering industry, electricity providers and companies who are interested in substation automation systems using wireless communication technologies for smart grid applications. Researchers, engineers and students studying and working in wireless communication will also want to buy this book as a reference.

This book provides the latest research on a new alternative form of technology, the magnetocaloric energy conversion. This area of research concerns magnetic refrigeration and cooling, magnetic heat pumping and magnetic power generation. The book's systematic approach offers the theoretical basis of magnetocaloric energy conversion and its various sub domains and this is supported with the practical examples. Besides these fundamentals, the book also introduces potential solutions to engineering problems in magnetocalorics and to alternative technologies of solid state energy conversion. The aim of the book is therefore to provide engineers with the most up-to-date information and also to facilitate the understanding, design and construction of future magnetocaloric energy conversion devices. The magnetocaloric energy conversion represents an alternative to compressor based refrigerators and heat pumps. It is a serious alternative to power generation with low enthalpy heat sources. This green technology offers an opportunity to use environmentally friendly solid refrigerants and the potentially high energy efficiency follows the trends of future energy conversion devices. This book is intended for postgraduate students and researchers of refrigeration, heat pumping, power generation alternatives, heat regenerators and advanced heat transfer mechanisms.
