  • Mechatronic Hands: Prosthetic and Robotic Design
  • This book describes the technical design characteristics of the main components that go into forming an artificial hand, whether it is a simple design that does not have a natural appearance, or a more complicated design where there are multiple movements of the fingers and thumb. Mechanical components obviously form the structure of any hand, while there are some lesser known ideas that need to be explored such as how to process a slip signal. The focus of the book is the design of artificial hands for people, who through trauma or congenitally, only have one or no natural hands, with an emphasis on myolectric hands - powered hands that are controlled by the small electrical signals from residual muscles. An in-depth treatment of mechanisms, sensors, control, and hand assessment is included. Bringing together decades of research from the University of Southampton - a centre of excellence in this field - this book is essential reading for researchers and advanced students of robotics, prosthetics and mechatronics as well as professional engineers and prosthetists in universities, industry and hospitals who are involved in the design and manufacture of prosthetic hands.

image of Nano-Scaled Semiconductor Devices: Physics, Modelling, Characterisation, and Societal Impact
  • Nano-Scaled Semiconductor Devices: Physics, Modelling, Characterisation, and Societal Impact
  • The subject of nano-scaled semiconductor devices and technology is a strategic and emerging area of relevant societal importance in our ubiquitous electronics era. This book is intended for scientists, engineers, and graduate students involved in the research, technology development, education activities, and societal-related applications where nano-scaled semiconductor devices are involved. With the rapid evolution of the integrated circuit technology many new materials and fabrication processing steps have been incorporated. These new materials and processing steps enhance the electrical performance of nano-scaled semiconductor devices, resulting in faster, more functional and complex electronics. However, this boosted capacity comes with second-order effects that degrade device performance, impact its longterm reliability, energy-efficiency and ultimately contribute to worldwide energy waste and subsequent pollution. The characterization, modeling, and simulation prediction of these second-order effects is strongly correlated to each other. Therefore, this book, in a novel approach, attempts to blend the technology fabrication, with the characterization, physics, and modeling in a synergistic manner. For instance, the shrinkage of the device dimensions down to 14 nm and below pose a big challenge for the development of appropriate transport modeling mechanisms, which in turn require advanced characterization and modeling techniques. The characterization techniques, developed for studying transport in nano-scaled devices, is also a novel contribution of this book. Blending the characterization, modeling, physics, and technology is quite relevant for achieving energy-efficient electronics. Moreover, there is a benefit that device developers can get out from the complex nano-scaled semiconductor device technologies. This is also a topic that this book covers. The potential use of these new materials and structures for the development of new and alternative devices or functions, such as water decontamination, energy renewal, physiology research, energy-efficient milk and meat production, or optimal and energy-efficient crop irrigation. This book also correlates the fundamental physics and device electrical performance with energy efficiency, energy savings, and thus contributes to the development of a greener and more sustainable world.

image of Foundations for Model-based Systems Engineering: From Patterns to Models
  • Foundations for Model-based Systems Engineering: From Patterns to Models
  • The practice of Model-based Systems Engineering is becoming more widely adopted in industry, academia and commerce and, as the use of modelling matures in the real world, so the need for more guidance on how to model effectively and efficiently becomes more prominent. This book describes a number of systems-level 'patterns' (pre-defined, reusable sets of views) that may be applied using the systems modelling language SysML for the development of any number of different applications and as the foundations for a system model. Topics covered include: what is a pattern? Interface definition pattern; traceability pattern; test pattern; epoch pattern; life cycle pattern; evidence pattern; description pattern; context pattern; analysis pattern; model maturity pattern; requirements modelling; expanded requirements modelling; process modelling; competence modelling; life cycle modelling; defining patterns; and using patterns for model assessment, model definition and for model retro-fitting. This book forms a companion volume to both 'SysML for Systems Engineering - a model-based approach' and 'Model-based Requirements Engineering', both published by the IET. Whereas the previous volumes presented the case for modelling and provided an in-depth overview of SysML, this book focusses on a set of 'patterns' as the basis of an MBSE model and their use in today's systems engineering community.

image of Nano-CMOS and Post-CMOS Electronics: Circuits and Design
  • Nano-CMOS and Post-CMOS Electronics: Circuits and Design
  • The demand for ever smaller and portable electronic devices has driven metal oxide semiconductor-based (CMOS) technology to its physical limit with the smallest possible feature sizes. This presents various size-related problems such as high power leakage, low-reliability, and thermal effects, and is a limit on further miniaturization. To enable even smaller electronics, various nanodevices including carbon nanotube transistors, graphene transistors, tunnel transistors and memristors (collectively called post-CMOSdevices) are emerging that could replace the traditional and ubiquitous silicon transistor. This book explores these nanoelectronics at the circuit and systems levels including modelling and design approaches and issues. Topics covered include self-healing analog and radio frequency circuits; on-chip gate delay variability measurement in scaled technology node; nanoscale finFET devices for PVT aware SRAM; data stability and write ability enhancement techniques for finFET SRAM circuits; low-leakage techniques for nanoscale CMOS circuits; thermal effects in carbon nanotube VLSI interconnects; lumped electro-thermal modeling and analysis of carbon nanotube interconnects; high-level synthesis of digital integrated circuits in the nanoscale mobile electronics era; SPICEless RTL design optimization of nanoelectronic digital integrated circuits; green on-chip inductors for threedimensional integrated circuits; 3D network-on-chips; and DNA computing. This book is essential reading for researchers, research-focused industry designers/developers, and advanced students working on next-generation electronic devices and circuits.

  • Power Distribution Automation
  • Utilities around the world are under increasing pressure to provide reliable and good quality power supply to their retail customers, and to reduce their operational costs. These concerns call for real time monitoring and control of the distribution system, which can be accomplished by deploying distribution automation (DA) systems, a key enabling technology for smart grids. This book provides a detailed description of all the major components of a DA system, including communication infrastructure and analysis tools. Topics covered include communication systems for distribution automation; load flow analysis; short circuit analysis; state estimation; feeder reconfiguration for loss reduction, service restoration, and load balancing; volt-var control; fault location; fault type identification; and economic analysis/cost benefit analysis. Concluding with an international case study (Enexis, one of the major Distribution System Operators in The Netherlands) showing how DA has been implemented in practice, this book is essential reading for researchers and advanced students working in power engineering and practitioners engaged in distribution automation, such as utility engineers, vendors, and consultant
