  • Wearable Exoskeleton Systems Design, control and applications
  • Wearable exoskeletons are electro-mechanical systems designed to assist, augment, or enhance motion and mobility in a variety of human motion applications and scenarios. The applications, ranging from providing power supplementation to assist the wearers to situations where human motion is resisted for exercising applications, cover a wide range of domains such as medical devices for patient rehabilitation training recovering from trauma, movement aids for disabled persons, personal care robots for providing daily living assistance, and reduction of physical burden in industrial and military applications. The development of effective and affordable wearable exoskeletons poses several design, control and modelling challenges to researchers and manufacturers. Novel technologies are therefore being developed in adaptive motion controllers, human-robot interaction control, biological sensors and actuators, materials and structures, etc. In this book, the authors report recent advances and technology breakthroughs in exoskeleton developments. It will be of interest to engineers and researchers in academia and industry as well as manufacturing companies interested in developing new markets in wearable exoskeleton robotics.

  • System Design with Memristor Technologies
  • Memristors are a new class of circuit element with the ability to change their resistance value while retaining memory of their current and past resistances. Their small form factor, high density, and fast switching times have sparked research into their applications in modern memory hierarchies. However, these new components pose system design challenges, as well as opportunities. System Design with Memristor Technologies explores design solutions for memristors, covering research and development trends in memristor technology, fabrication, modelling, and applications, and the design and implementation of arithmetic units using memristors. The book begins with an introduction to the principles of system design with memristors, then goes on to address memristor logic gates, arithmetic units for adders, multipliers and dividers, and improved and optimised adder, multiplier and divider designs. The final chapters draw conclusions from the topics covered and explore potential future trends in research into system designs with memristor technologies. This book is essential reading for research scientists and electronics engineers interested in the use of memristors in future system architectures, specifically focused on the areas of arithmetic units, non-Von-Neumann architectures, and logic-in-memory

  • Engineering High Quality Medical Software: Regulations, standards, methodologies and tools for certification
  • No longer confined to medical devices, medical software has become a pervasive technology giving healthcare operators access to clinical information stored in electronic health records and clinical decision support systems, supporting robot-assisted telesurgery, and providing the technology behind ambient assisted living. These systems and software must be designed, built and maintained according to strict regulations and standards to ensure that they are safe, reliable and secure. Engineering High Quality Medical Software illustrates how to exploit techniques, methodologies, development processes and existing standards to realize high-confidence medical software. After an introductory survey of the topic the book covers global regulations and standards (including EU MDD 93/42/EEC, FDA Title 21 of US CFR, ISO 13485, ISO 14971, IEC 52304, IEEE 1012 and ISO/IEC 29119), verification and validation techniques and techniques, and methodologies and engineering tasks for the development, configuration and maintenance of medical software.

  • Handbook of Speckle Filtering and Tracking in Cardiovascular Ultrasound Imaging and Video
  • Ultrasound imaging technology has experienced a dramatic change in the last 30 years. Because of its non-invasive nature and continuing improvements in image quality, ultrasound imaging is progressively achieving an important role in the assessment and characterization of cardiovascular imaging. Speckle is inherent in ultrasound imaging giving rise to a granular appearance instead of homogeneous, flat shades of gray, as is visible and as such, speckle can severely compromise interpretation of ultrasound images, particularly in discrimination of small structures. On the other hand, speckle can be used in the detection of time varying phenomena, or tracking tissue motion. The objective of this book is to provide a reference edited volume covering the whole spectrum of speckle phenomena, theoretical background and modelling, algorithms and selected applications in cardiovascular ultrasound imaging and video processing and analysis. The book is organized under the following four parts, Part I: Introduction to Speckle Noise; Part II: Speckle Filtering; Part III: Speckle Tracking; Part IV: Selected Applications in Cardiovascular Imaging.

image of High Voltage Power Network Construction
  • High Voltage Power Network Construction
  • High Voltage Power Network Construction examines the key requirements, considerations, complexities and constraints relevant to the task of high voltage power network construction - from design, finance, contracts and project management to installation and commissioning - with the aim of providing an overview of the holistic end to end construction task in a single volume. It specifically targets the 400, 275,132 and 33 kV networks, presenting best and common practice. The book is organised around the implementation of three complementary deliverables: a technical solution that results in the required power system performance characteristics; appropriate quality management arrangements; and the set of competencies all duty holders should demonstrate. Although written primarily from a UK electrical power industry perspective, the book recognises that much is already harmonised with the rest of Europe and increasingly so the rest of the world. This comprehensive reference is a must-read for engineers and researchers with high voltage network construction related responsibilities, especially those engineers that are newly qualified, as well as further reading for advanced students in related subjects.

  • Tactical Persistent Surveillance Radar with Applications
  • Tactical Persistent Surveillance Radar with Applications introduces technologists to the essential elements of persistent surveillance of tactical targets from both a hardware and software point of view, using simple Mathcad, Excel and Basic examples with real data. It is based on the type of surveillance done by drones like Scan Eagle, Predator, Reaper, Global Hawk, and manned aircraft like U-2, ASTOR, and JSTARS as well as spacecraft. The general topic is cellphone and datalink intercept, ground moving target radar, synthetic aperture radar, navigation, tracking, electronic scanning and cueing electro-optical sensors for activity based surveillance. Examples are taken from a wide range of technologies and techniques including passive detection, radar detection, antenna monopulse, active electronic scanned antennas (AESA), moving target tracking (MTT), motion compensation, tactical target spectral characteristics, moving target detection (MTI), space time adaptive processing (STAP), synthetic aperture radar (SAR) imaging, change detection (CCD), and synthetic monopulse. Over 120 example applications programs are included in the appendices and as downloads as well as over 100 SAR and GMTI raw IQ data files. These allow the curious to experiment with their own parameters and notions to achieve a greater understanding of the underlying behaviors. Based on the author's 55-year experience in engineering design, leadership, teaching and consulting, this book is an essential text for researchers, advanced students and technologists working in radar and related fields in computing and aerospace system design.

image of Road Pricing: Technologies, economics and acceptability
  • Road Pricing: Technologies, economics and acceptability
  • Road pricing is increasingly being implemented around the world to combat congestion, curb carbon and other polluting emissions, compensate for falling revenues from fuel duty, improve the efficiency of the existing transport infrastructure, and fund new transport projects. Road Pricing outlines some of the economic theory behind these schemes, indicates the different kinds of road charging schemes that are possible, describes the electronic technology being used, shows that it is available and already in operational use in many countries, addresses how public acceptability can be achieved, and demonstrates that people will accept road pricing if they understand the reasons for using it, and above all, if they have experienced it in use and understand how it will affect them personally. There are very few engineering-oriented books in this field, or books aimed at transport planners. This book aims to fill that gap - informing engineers and planners how to prepare for and implement road pricing schemes, which technologies to use, and which technologies are already in use successfully throughout the world. The book also aims to show politicians and policy advisors what has been successfully achieved and what is possible now and in the immediate future.

  • The Inverted Pendulum in Control Theory and Robotics: From theory to new innovations
  • The inverted pendulum is a classic problem in dynamics and control theory and is widely used as a benchmark for testing control algorithms. It is also an area of active study, with many new innovations and applications - for example, the problem is solved in the technology of the Segway, a self-balancing transportation device. This book provides an overall picture of historical and current trends and the developments in nonlinear control theory, based on the simple structure and rich nonlinear model of the inverted pendulum. After an introduction to the system and open/current problems, the book covers the topic in four parts: applications of robust state estimation and control to pendulum-cart systems; controllers for under-actuated mechanical systems; nonlinear controllers for mobile inverted pendulum systems; and robust controllers based observers via Takagi-Sugeno or linear approaches. With contributions from international researchers in the field, The Inverted Pendulum in Control Theory and Robotics is essential reading for researchers, scientists, engineers and students in the field of control theory, robotics and nonlinear systems
