Digital Twins for Wireless Networks: Overview, Architecture, and Challenges
by Waleed Ejaz Muhammad Khalil Afzal Muhammad NaeemThe sixth-generation (6G) communication systems are anticipated to provide network connectivity for an extensive range of use cases in a variety of emerging vertical industries. Consequently, a new set of challenging requirements and more stringent key performance indicators have to be considered, a novel architecture has to be designed, and unique enabling technologies shall be developed in order to fulfil the technical, regulatory, and business demands of the communication service customers. 6G networks are expected to offer even faster speeds, lower latency, and greater capacity compared to 5G networks, which will enable new applications and use cases that are currently not possible. Improved quality of life by enabling various applications (emerging Internet of everything applications) such as healthcare, brain-computer interactions, and extended reality is the main focus of future wireless services. Quality of experience, latency, and reliability are the key requirements of these applications. To meet these diverse requirements there is a need to assist wireless systems with unique technologies. Self-sustaining wireless systems (intelligence, seamless and ubiquitous connectivity) and proactive-online-learning-enables systems (Intelligent analytics) are two trends in future wireless systems. The digital twin technology is one of the most promising technologies that can be instrumental in realizing the technical and business objectives of 6G communication systems. A digital twin is a virtual imitation of a physical object or system. In a wireless system, a digital twin can be used to model and analyse the behaviour of the network and its components, such as antennas, transmitters, receivers, sensors, and other devices in wireless networks. One of the key benefits of using a digital twin for a wireless system is that it can help network operators and engineers to optimize the performance of the wireless network by simulating different scenarios and configurations. Other benefits include improve efficiency, cost saving, and enhanced security. In 6G networks, a digital twin could be used to simulate and optimize the performance. This could include simulating different network topologies, testing the performance of different network protocols and algorithms, and optimizing the placement of network infrastructure. To create a digital twin of a wireless network, a detailed model of the network and its components must be developed, based on real-world data and conditions. This model can then be used to simulate the behaviour of the network under different conditions and settings and to visualize the results in real time.

Digital Unsettling: Decoloniality and Dispossession in the Age of Social Media (Critical Cultural Communication)
by Sahana Udupa 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 (FREE Extended Extract): How today's online social revolution is dividing, diminishing and disorienting us
by Andrew KeenThis an Extended Extract of Digital Vertigo to be published on May 22nd 2012. You can follow Andrew Keen: @ajkeenIn 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.

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. What you'll learn Cost-benefit analysis of compression techniques Video quality metrics evaluation Performance and power optimization and measurement Trade-off analysis among power, performance, and visual quality Emerging uses and applications of video technologies Who this book is for This book is for anyone involved in designing, developing, validating, deploying, and reviewing systems and applications that deal with digital video.

Digital Virtual Consumption (Routledge Studies in Innovation, Organizations and Technology)
by Janice Denegri-Knott Mike MolesworthDigital media present opportunities for new types of consumption including desiring, buying, collecting, making, and even selling digital virtual goods. To these activities we can add those taking place in virtual communities of consumption, online shops, brand websites, and online auction houses that together amount to a vast new landscape of consumption. Digital virtual consumption motivates concatenated practices which produce meaningful experience for their users as well as market opportunities to profit from them. Consumers create and maintain elaborate wish lists, engaging with simulations of brands on websites and in videogames, coveting items for use in online games and even spending ‘real’ money on these, undertaking entrepreneurial activity in virtual worlds, conjuring nostalgia via online auctions, engaging in playful consumption in other new retail formats, writing reviews of products as part of the consumption experience, engaging in online activist activities, and many other emerging behaviors. Analyses of consumption in the digital virtual realm are however limited. This collection brings together experienced researchers from the fields of consumer research, digital games, and virtual worlds to provide conceptual and empirical work that helps us understand these new and significant consumer activities. Online communities negotiate the ‘correct’ use of goods and offer technical advice, consumers develop new products, individuals create and distribute their own promotional material for their favorite brands, and entrepreneurial consumers marketing and selling their own products online. Here we may see a blurring of consumption and production, or work and leisure activity that requires further thought about what makes it meaningful for individuals. The chapters in this volume take stock of the emergence and likely importance of digital virtual consumption for consumer culture, including a review of both new and existing conceptual and methodological tools as well as a resource of key examples and analyses of practices.

Digital Watermarking Techniques in Curvelet and Ridgelet Domain
by Channapragada Rama Seshagiri Rao Munaga V. N. K. PrasadThis book describes the design, development, and testing of a novel digital watermarking technique for color images using Magic Square and Ridgelet transforms. The novel feature of the method is that it generates and uses multiple copies of the digital watermark. The book describes how the method was tested for embedding digital watermarks into color cover images, resulting in very high PSNR value and yielding comparable results with existing watermarking techniques. To reach this new method, eight different techniques are designed, developed and tested. First, the authors test two digital watermarking techniques based on encryption: Image Watermark Using Complete Complementary Code Technique (CCCT) and Image Watermarking Using CCC-Fast Walsh Hadamard Transform Technique (CCC-FWHTT). Next, four digital watermarking techniques based on curvelet transforms are discussed: Image Watermarking Using Curvelet Transform (WCT), Watermark Wavelets in Curvelets of Cover Image (WWCT), Resized Watermark into Curvelets of Cover Image (RWCT), and Resized Watermark Wavelets into Curvelets of Cover Image (RWWCT). Then, two final techniques are presented: Image Watermarking Based on Magic Square (MST) and Image watermarking based on Magic Square and Ridgelet Transform (MSRTT). Future research directions are explored in the final chapter. Designed for professionals and researchers in computer graphics and imaging, Digital Watermarking Techniques in Curvelet and Ridgelet Domain is also a useful tool for advanced-level students.

Digital Watermarking for Machine Learning Model: Techniques, Protocols and Applications
by Chee Seng Chan Qiang Yang Lixin FanMachine learning (ML) models, especially large pretrained deep learning (DL) models, are of high economic value and must be properly protected with regard to intellectual property rights (IPR). Model watermarking methods are proposed to embed watermarks into the target model, so that, in the event it is stolen, the model’s owner can extract the pre-defined watermarks to assert ownership. Model watermarking methods adopt frequently used techniques like backdoor training, multi-task learning, decision boundary analysis etc. to generate secret conditions that constitute model watermarks or fingerprints only known to model owners. These methods have little or no effect on model performance, which makes them applicable to a wide variety of contexts. In terms of robustness, embedded watermarks must be robustly detectable against varying adversarial attacks that attempt to remove the watermarks. The efficacy of model watermarking methods is showcased in diverse applications including image classification, image generation, image captions, natural language processing and reinforcement learning. This book covers the motivations, fundamentals, techniques and protocols for protecting ML models using watermarking. Furthermore, it showcases cutting-edge work in e.g. model watermarking, signature and passport embedding and their use cases in distributed federated learning settings.
