Digital worlds and cultures-social media, web 2.0, youtube, wearable technologies, health and fitness apps-dominate, if not order, our everyday lives. We are no longer 'just' consumers or readers of digital culture but active producers through facebook, twitter, Instagram, youtube and other emerging technologies. This book is predicated on the assumption that out understanding of our everyday lives should be informed by what is taking place in and through emerging technologies given these (virtual) environments provide a crucial context where traditional, categorical assumptions about the body, identity and leisure may be contested. Far from being 'virtual', the body is constituted within and through emerging technologies in material ways. Recent 'moral panics' over the role of digital cultures in teen suicide, digital drinking games, an endless array of homoerotic images of young bodies being linked with steroid use, disordered eating and body dissatisfaction, facebook games/fundraising campaigns (e.g. for breast cancer), movements devoted to exposing 'everyday sexism' / metoo, twitter abuse (of feminists, of athletes, of racist nature to name but a few), speak to the need for critical engagement with digital cultures. While some of the earlier techno-utopian visions offered the promise of digitality to give rise to participatory, user generator collaborations, within this book we provide critical engagement with digital technologies and what this means for our understandings of leisure cultures. The chapters originally published in a special issue in Leisure Studies.

The third edition of Digital Logic Techniques provides a clear and comprehensive treatment of the representation of data, operations on data, combinational logic design, sequential logic, computer architecture, and practical digital circuits. A wealth of exercises and worked examples in each chapter give students valuable experience in applying the concepts and techniques discussed. Beginning with an objective comparison between analogue and digital representation of data, the author presents the Boolean algebra framework for digital electronics, develops combinational logic design from first principles, and presents cellular logic as an alternative structure more relevant than canonical forms to VLSI implementation. He then addresses sequential logic design and develops a strategy for designing finite state machines, giving students a solid foundation for more advanced studies in automata theory. The second half of the book focuses on the digital system as an entity. Here the author examines the implementation of logic systems in programmable hardware, outlines the specification of a system, explores arithmetic processors, and elucidates fault diagnosis. The final chapter examines the electrical properties of logic components, compares the different logic families, and highlights the problems that can arise in constructing practical hardware systems.

Until recently, most network design techniques employed a bottom-up approach with lower protocol layer mechanisms affecting the development of higher ones. This approach, however, has not yielded fascinating results in the case of wireless distributed networks. Addressing the emerging aspects of modern network analysis and design, Evolutionary Dynamics of Complex Communications Networks introduces and develops a top-bottom approach where elements of the higher layer can be exploited in modifying the lowest physical topology-closing the network design loop in an evolutionary fashion similar to that observed in natural processes. This book provides a complete overview of contemporary design approaches from the viewpoint of network science and complex/social network analysis. A significant part of the text focuses on the classification and analysis of various network modification mechanisms for wireless decentralized networks that exploit social features from relevant online social networks. Each chapter begins with learning objectives and introductory material and slowly builds to more detailed analysis and advanced concepts. Each chapter also identifies open issues, while by the end of the book, potential research directions are summarized for the more interested researcher or graduate student. The approach outlined in the book will help network designers and administrators increase the value of their infrastructure without requiring any significant additional investment. Topics covered include: basic network graph models and properties, cognitive methods and evolutionary computing, complex and social network analysis metrics and features, and analysis and development of the distinctive structure and features of complex networks. Considering all aspects of modern network analysis and design, the text covers the necessary material and background to make it a suitable source of reference for graduate students, postdoctoral researchers, and scientists

This book describes the design and implementation of an electronic subsystem called the frequency synthesizer, which is a very important building block for any wireless transceiver. The discussion includes several new techniques for the design of such a subsystem which include the usage modes of the wireless device, including its support for several leading-edge wireless standards. This new perspective for designing such a demanding subsystem is based on the fact that optimizing the performance of a complete system is not always achieved by optimizing the performance of its building blocks separately. This book provides "hands-on" examples of this sort of co-design of optimized subsystems, which can make the vision of an always-best-connected scenario a reality."
