This volume provides an introduction to and overview of the emerging field of interconnected networks which include multilayer or multiplex networks, as well as networks of networks. Such networks present structural and dynamical features quite different from those observed in isolated networks. The presence of links between different networks or layers of a network typically alters the way such interconnected networks behave - understanding the role of interconnecting links is therefore a crucial step towards a more accurate description of real-world systems. While examples of such dissimilar properties are becoming more abundant - for example regarding diffusion, robustness and competition - the root of such differences remains to be elucidated. Each chapter in this topical collection is self-contained and can be read on its own, thus making it also suitable as reference for experienced researchers wishing to focus on a particular topic.
The book outlines the concept of the Automated City, in the context of smart city research and development. While there have been many other perspectives on the smart city such as the participatory city and the data-centric city, this book focuses on automation for the smart city based on current and emerging technologies such as the Internet of Things, Artificial Intelligence and Robotics. The book attempts to provide a balanced view, outlining the promises and potential of the Automated City as well as the perils and challenges of widespread automation in the city. The book discusses, at some depth, automated vehicles, urban robots and urban drones as emerging technologies that will automate many aspects of city life and operation, drawing on current work and research literature. The book also considers broader perspectives of the future city, in the context of automation in the smart city, including aspirational visions of cities, transportation, new business models, and socio-technological challenges, from urban edge computing, ethics of the Automated City and smart devices, to large scale cooperating autonomous systems in the city.
Quality of Telephone-Based Spoken Dialogue Systems is a systematic overview of assessment, evaluation, and prediction methods for the quality of services such as travel and touristic information, phone-directory and messaging, or telephone-banking services. A new taxonomy of quality-of-service is presented which serves as a tool for classifying assessment and evaluation methods, for planning and interpreting evaluation experiments, and for estimating quality. A broad overview of parameters and evaluation methods is given, both on a system-component level and for a fully integrated system. Three experimental investigations illustrate the relationships between system characteristics and perceived quality. The resulting information is needed in all phases of system specification, design, implementation, and operation. Although Quality of Telephone-Based Spoken Dialogue Systems is written from the perspective of an engineer in telecommunications, it is an invaluable source of information for professionals in signal processing, communication acoustics, computational linguistics, speech and language sciences, human factor design and ergonomics

As the feature size decreases in deep sub-micron designs, coupling
capacitance becomes the dominant factor in total capacitance. The
resulting crosstalk noise may be responsible for signal integrity
issues and significant timing variation. Traditionally, static
timing analysis tools have ignored cross coupling effects between
wires altogether. Newer tools simply approximate the coupling
capacitance by a 2X Miller factor in order to compute the worst
case delay. The latter approach not only reduces delay calculation
accuracy, but can also be shown to underestimate the delay in
certain scenarios. -Spatial pruning - reducing aggressors to those in physical
proximity,
This book provides an excellent mix of theory and practice. Starting with information theory and classical coding theory, the text covers the message passing concept that forms the basis of modern coding techniques, including turbo codes and Low Density Parity Check (LDPe codes, and then discusses a large number of turbo code combinations - including industry standards such as DVB-RCS, 3GPP, and CDMA2000. Numerous implementation issues and examples of commercially available turbo codes and products are explored in detail. This comprehensive treatment of the topic will enable the reader to select, evaluate, and implement the turbo code suitable for their application. Programs for the simulation of several turbo coding schemes, including those in DVB-RCS and 3GPP standards, are included in the accompanying CD-ROM. These C programs can be easily used for simulation and performance evaluation and serve as a starting point for a design effort. FPGA, ASIC, and DSP sample implementations are also presented. Source files, instead of executables, are included so that the reader can modify the programs and tailor them to his/her needs. Practising engineers involved in the design of communication circuits and systems and graduate students conducting research in the area of digital communications will benefit from this balanced and insightful treatment. The coverage of different system level concepts, various wireless and satellite communications standards, and the available turbo code products makes this work a valuable reference for engineering managers.

This text introduces the reader to the theory of multi-port signals and systems, with a focus on vector-valued signal transmission. Of primary interest is the dynamic behavior of electrical multiple-input multiple-output (MIMO) systems. The book provides a basic understanding of the fundamentals, implementation, and applications of MIMO techniques. These techniques, in conjunction with several "classic" signal processing algorithms, are illustrated by means of numerous worked examples and software on the accompanying CD-ROM. MATLABA(R). This matrix-oriented commercial software package with user-friendly interfaces and excellent graphics support was chosen to perform the numerical analyses. End-of-chapter problems are added to provide additional training opportunities and to reinforce the knowledge gained. Over the last decade, spurred by the invention of a series of fundamentally new wireless transmission concepts, MIMO theory has been transformed into one of the most vibrant and active research areas. A person with no previous training or experience in the various fields of electromagnetics, radio technology, wireless transmission systems, coding and digital modulation theory, etc., is in danger of getting lost right at the start of a MIMO project. It is the purpose of this text to take away at least some of the load from students, researchers, and interested practitioners. It can be used in telecommunications transmission and switching, systems and information theory, and signal processing courses.

This book presents novel algorithms for designing Discrete-Time Sliding Mode Controllers (DSMCs) for Networked Control Systems (NCSs) with both types of fractional delays namely deterministic delay and random delay along with different packet loss conditions such as single packet loss and multiple packet loss that occur within the sampling period. Firstly, the switching type and non-switching type algorithms developed for the deterministic type fractional delay where the delay is compensated using Thiran's approximation technique. A modified discrete-time sliding surface is proposed to derive the discrete-time sliding mode control algorithms. The algorithm is further extended for the random fractional delay with single packet loss and multiple packet loss situations. The random fractional delay is modelled using Poisson's distribution function and packet loss is modelled by means of Bernoulli's function. The condition for closed loop stability in all above situations are derived using the Lyapunov function. Lastly, the efficacy of the proposed DSMC algorithms are demonstrated by extensive simulations and also experimentally validated on a servo system.
Echo Signal Processing is designed for engineers and scientists who have an interest in signal processing and/or acoustics and are working in areas related to echo-location and sonar. Academics who are teaching signal processing courses in detection and estimation relating to echo-location can use the book either as a primary text or as a backup source. This book presents introductory and advanced topics in the areas of signal theory and processing as specifically applied to acoustic echo-location. It is written at the senior undergraduate or graduate level and assumes some familiarity with signal processing subjects such as linear and complex algebra, probability, advanced calculus, and linear system theory. The material is presented as a logical development starting with the basic principles of signal theory and proceeds to the development of topics in detection and estimation theory, waveform design, echo modeling, scattering theory, and spatial processing. Echo Signal Processing addresses the practical as well as theoretical aspects of receiver and waveform design and should be of interest to the practicing engineer as well as the student. Numerous examples demonstrating the concepts are provided and important relationships are boxed. The book departs from many radar-oriented texts as the effects of relative motion are treated in terms of the dilation of the signal time base rather than as a simple Doppler frequency shift. The fundamental detection, estimation, time dilation, and waveform theory presented is of a general nature and applicable to communications and radar as well as sonar.
