Digital Twin and Blockchain for Smart Cities
by Amit Kumar TyagiThe book uniquely explores the fundamentals of blockchain and digital twin technologies and their uses in smart cities. In the previous decade, many governments explored artificial intelligence, digital twin, and blockchain, and their roles in smart cities. This book discusses the convergence of two transformative technologies, digital twin and blockchain, to address urban challenges and propel the development of smarter, more sustainable cities. This convergence empowers cities to create real-time replicas of urban environments (digital twins) and secure, transparent data management (blockchain) to improve city planning, management, and civic services. In this application, the concept of a digital twin involves creating a virtual, data-driven replica of a city or specific urban systems, such as transportation, energy, or infrastructure. This digital twin mirrors the real world, gathering data from various sensors, IoT devices, and other sources to provide a holistic view of the city’s operations. Furthermore, blockchain technology offers a decentralized and tamper-resistant ledger for securely storing and managing data. In the context of smart cities, blockchain can ensure data integrity, privacy, and transparency, enabling trust and collaboration among various stakeholders. This book covers many important topics, including real-time city modeling; data security and the trustworthy storage of sensitive urban data; transparent governance to facilitate accountable governance and decision-making processes in smart cities; improved city services; disaster resilience (by providing insights into vulnerabilities and efficient resource allocation during crises); sustainable urban planning that optimizes resource allocation, reduces energy consumption, and minimizes environmental impact, which fosters sustainable development; citizen engagement; and much more. This book will not only provide information about more efficient, resilient, and sustainable urban environments, but it also empowers citizens to be active participants in shaping the future of their cities. By converging these technologies, cities can overcome existing challenges, encourage innovation, and create more livable, connected, and responsive urban spaces.

Digital Unsettling: Decoloniality and Dispossession in the Age of Social Media (Critical Cultural Communication)
by null Sahana Udupa null Ethiraj Gabriel DattatreyanHow digital networks are positioned within the enduring structures of colonialityThe revolutionary aspirations that fueled decolonization circulated on paper—as pamphlets, leaflets, handbills, and brochures. Now—as evidenced by movements from the Arab Spring to Black Lives Matter—revolutions, protests, and political dissidence are profoundly shaped by information circulating through digital networks. Digital Unsettling is a critical exploration of digitalization that puts contemporary “decolonizing” movements into conversation with theorizations of digital communication. Sahana Udupa and Ethiraj Gabriel Dattatreyan interrogate the forms, forces, and processes that have reinforced neocolonial relations within contemporary digital environments, at a time when digital networks—and the agendas and actions they proffer—have unsettled entrenched hierarchies in unforeseen ways. Digital Unsettling examines events—the toppling of statues in the UK, the proliferation of #BLM activism globally, the rise of Hindu nationalists in North America, the trolling of academics, among others—and how they circulated online and across national boundaries. In doing so, Udupa and Dattatreyan demonstrate how the internet has become the key site for an invigorated anticolonial internationalism, but has simultaneously augmented conditions of racial hierarchy within nations, in the international order, and in the liminal spaces that shape human migration and the lives of those that are on the move. Digital Unsettling establishes a critical framework for placing digitalization within the longue durée of coloniality, while also revealing the complex ways in which the internet is entwined with persistent global calls for decolonization.

Digital Vertigo: How Today's Online Social Revolution Is Dividing, Diminishing, and Disorienting Us
by Andrew KeenIn Digital Vertigo, Andrew Keen presents today's social media revolution as the most wrenching cultural transformation since the Industrial Revolution. Fusing a fast-paced historical narrative with front-line stories from today's online networking revolution and critiques of "social" companies like Groupon, Zynga and LinkedIn, Keen argues that the social media transformation is weakening, disorienting and dividing us rather than establishing the dawn of a new egalitarian and communal age.The tragic paradox of life in the social media age, Keen says, is the incompatibility between our internet longings for community and friendship and our equally powerful desire for online individual freedom. By exposing the shallow core of social networks, Andrew Keen shows us that the more electronically connected we become, the lonelier and less powerful we seem to be.Praise forThe Cult of the Amateur:'A shrewdly argued jeremiad against the digerati effort to dethrone cultural and political gatekeepers and replace experts with 'the wisdom of the crowd'.

Digital Video Concepts, Methods, and Metrics: Quality, Compression, Performance, and Power Trade-off Analysis
by Shahriar AkramullahDigital Video Concepts, Methods, and Metrics: Quality, Compression, Performance, and Power Trade-off Analysis is a concise reference for professionals in a wide range of applications and vocations. It focuses on giving the reader mastery over the concepts, methods and metrics of digital video coding, so that readers have sufficient understanding to choose and tune coding parameters for optimum results that would suit their particular needs for quality, compression, speed and power. The practical aspects are many: Uploading video to the Internet is only the beginning of a trend where a consumer controls video quality and speed by trading off various other factors. Open source and proprietary applications such as video e-mail, private party content generation, editing and archiving, and cloud asset management would give further control to the end-user. Digital video is frequently compressed and coded for easier storage and transmission. This process involves visual quality loss due to typical data compression techniques and requires use of high performance computing systems. A careful balance between the amount of compression, the visual quality loss and the coding speed is necessary to keep the total system cost down, while delivering a good user experience for various video applications. At the same time, power consumption optimizations are also essential to get the job done on inexpensive consumer platforms. Trade-offs can be made among these factors, and relevant considerations are particularly important in resource-constrained low power devices. To better understand the trade-offs this book discusses a comprehensive set of engineering principles, strategies, methods and metrics. It also exposes readers to approaches on how to differentiate and rank video coding solutions.
