  • Industrial Power Systems with Distributed and Embedded Generation
  • Energy for today's complex electrical power systems is increasingly being generated and distributed locally using small-scale, renewable energy sources. The addition of renewables to the grid requires new tools and operation methods, both for suppliers and industrial consumers. This book describes the supporting technologies that can turn conventional passive electricity delivery networks into the active networks of the future, with a focus on electricity utilization in the industrial environment. It examines the integration of the new, dispersed sources with the legacy systems of centralised generation, as well as how the new technologies can operate effectively in isolated systems. Industrial power distribution, lighting, motor control and protection are discussed in detail. The presentation of the details of the enabling technologies makes this book a valuable reference for researchers, students and engineers involved in the planning, design and installation of new systems or the upgrading of existing ones.

  • Functionality-Enhanced Devices An alternative to Moore's Law
  • This book discusses one possible solution to the key issue in electronics engineering - the approaching limits of CMOS scaling - by taking advantage of the tendency of Schottky contacts to form at channel interfaces in nanoscale devices. Rather than suppressing this phenomenon, a functionality-enhanced device exploits it to increase switching functionality. These devices are Multiple-Independent-Gate-Field-Effect-Transistors, and other related nanoscale devices, whose polarity is electrostatically controllable. The functionality enhancement of these devices increases computational performance (function) per unit area and leads to circuits with better density, performance and energy efficiency. The book provides thorough and systematic coverage of enhanced-functionality devices and their use in proof-of-concept circuits and architectures. The theory and materials science behind these devices are addressed in detail, and various experimental fabrication techniques are explored. In addition, the potential applications of functionality-enhanced devices are outlined with a specific emphasis on circuit design, design automation and benchmarking.

  • Negative Group Delay Devices: From concepts to applications
  • Negative Group Delay Devices: From Concepts to Applications introduces the theoretical concept, analysis, design methodology and implementation of negative group delay (NGD). The NGD concept is a recent topic in electrical and electronic engineering research based on an unconventional function; the generation of an output signal seemingly in time-advance of the input signal. The NGD function has been exploited to develop experimental highperformance electronic devices, and novel design features of radio frequency (RF) and microwave electronic devices, such as filters, power dividers and amplifiers. Examples include the realization of non-Foster reactive elements, shortening or reducing delay lines, enhancing the efficiency of feedforward linear amplifiers, improvement of phase shifters accuracy and bandwidth, equalization of electrical interconnect effects for the microwave, digital and mixed signal integrity improvement, and minimizing beam-squint in series-fed antenna arrays. The aim of the book is to advance understanding of the NGD principle and its applications. Recent results and outcomes for the different methodologies used to elaborate the NGD function are shared in each chapter, and approaches relevant to various devices are described. This book will be of particular interest to researchers, academics and postdoctoral students interested in signal processing in electronic, radio frequency, microwave and optoelectronic devices, and particularly those investigating unconventional circuit and system design.

image of SysML for Systems Engineering: A Model-Based Approach
  • SysML for Systems Engineering: A Model-Based Approach
  • Systems Modelling Language (SysML) is a tailored version of the unified modelling language (UML) that meets the needs of today' s systems engineering professionals and engineers. It supports the specification, analysis, design, verification and validation of a broad range of systems and systems-of-systems, including hardware, software, information, personnel, procedures, and facilities in a graphical notation. SysML for Systems Engineering: A Model-Based Approach provides a comprehensive overview on how to implement SysML and Model-based Systems Engineering (MBSE) in an organisation in order to model real projects effectively and efficiently. Topics covered include approach and concepts; SysML notation; diagramming guidelines; process and requirements modelling with MBSE; architectures and architectural frameworks with MBSE; value chain modelling; deploying MBSE; the benefits of MBSE; the 'people', the 'process' and the 'tool'; model structure and management; and model maturity. A detailed case study is included to illustrate the key concepts. Fully updated and revised to reflect the latest version of the standard (SysML 1.5, released in May 2017), this new edition also includes new chapters on the benefits of MBSE, model management, model maturity and value chain modelling.

  • Network Design, Modelling and Performance Evaluation
  • Designed for ICT professionals involved in the planning, design, development, testing and operation of network services, this book is ideal for self-teaching. It will help readers evaluate a network situation and identify the most important aspects to be monitored and analysed. The author provides a detailed step by step methodological approach to network design from the analysis of the initial network requirements to architecture design, modeling, simulation and evaluation, with a special focus on statistical and queuing models. The chapters are structured as a series of independent modules that can be combined for designing university courses. Practice exercises are given for selected chapters, and case studies will take the reader through the whole network design process.

  • Fault Diagnosis for Robust Inverter Power Drives
  • Power drives are used for induction motor control, uninterruptible power supplies, and in electrical vehicles. The increasing penetration of power drives makes their reliability, robustness, and early diagnosis a central point of attention especially in planning, designing, and financing. This book explores fault diagnosis of inverter drives to enable early diagnosis and robust design for efficient long life operation. Fault Diagnosis for Robust Inverter Power Drives focuses on early diagnosis, prognosis, and intrinsic reliability of inverter power drives and their applications. Topics include material degradation, materials, semiconductors, inverter topologies, and early diagnosis as well as fault tolerant software strategies. This work is highly relevant to researchers, power electronics professionals, and system designers in aerospace, hybrid and electrical cars, and power systems.

  • Power Line Communication Systems for Smart Grids
  • Power Line Communication (PLC) is a well-established technology that allows the transmission of data through electrical wires. A key advantage of PLC is its low cost of deployment when the electrical wiring infrastructure already exists, enabling it to compete or work in conjunction with wireless technologies. PLC has recently received growing attention and significant investments within the development of the Smart Grid (SG), that in turn requires sophisticated data exchange and communication. This book presents a comprehensive introduction to the principals involved in the use of narrowband and broadband PLC technologies in the SG, and to using these technologies particularly when intermittent renewable energies sources are employed. Chapters cover fundamental concepts of modern digital communications, the main coding techniques, specific characteristics of the PLC channels, the fundamentals of the SG, and the differences between the narrowband and broadband technologies for SG applications. The work covers the main standards and several related state-of-the-art works, as well as some key aspects of the use of renewable energy sources. Power Line Communication Systems for Smart Grids is essential reading for researchers, professionals and graduate students involved with the study and development of PLC systems, SG and related subjects.
