    Get PDF
    Radio frequency fingerprint (RFF) identification is a promising technique for identifying Internet of Things (IoT) devices. This paper presents a comprehensive survey on RFF identification, which covers various aspects ranging from related definitions to details of each stage in the identification process, namely signal preprocessing, RFF feature extraction, further processing, and RFF identification. Specifically, three main steps of preprocessing are summarized, including carrier frequency offset estimation, noise elimination, and channel cancellation. Besides, three kinds of RFFs are categorized, comprising I/Q signal-based, parameter-based, and transformation-based features. Meanwhile, feature fusion and feature dimension reduction are elaborated as two main further processing methods. Furthermore, a novel framework is established from the perspective of closed set and open set problems, and the related state-of-the-art methodologies are investigated, including approaches based on traditional machine learning, deep learning, and generative models. Additionally, we highlight the challenges faced by RFF identification and point out future research trends in this field

    Multidisciplinary perspectives on Artificial Intelligence and the law

    This open access book presents an interdisciplinary, multi-authored, edited collection of chapters on Artificial Intelligence (‘AI’) and the Law. AI technology has come to play a central role in the modern data economy. Through a combination of increased computing power, the growing availability of data and the advancement of algorithms, AI has now become an umbrella term for some of the most transformational technological breakthroughs of this age. The importance of AI stems from both the opportunities that it offers and the challenges that it entails. While AI applications hold the promise of economic growth and efficiency gains, they also create significant risks and uncertainty. The potential and perils of AI have thus come to dominate modern discussions of technology and ethics – and although AI was initially allowed to largely develop without guidelines or rules, few would deny that the law is set to play a fundamental role in shaping the future of AI. As the debate over AI is far from over, the need for rigorous analysis has never been greater. This book thus brings together contributors from different fields and backgrounds to explore how the law might provide answers to some of the most pressing questions raised by AI. An outcome of the Católica Research Centre for the Future of Law and its interdisciplinary working group on Law and Artificial Intelligence, it includes contributions by leading scholars in the fields of technology, ethics and the law.info:eu-repo/semantics/publishedVersio

    Integrating ecosystem–based management and marine spatial planning for sustainable ocean governance in the Bay of Bengal

    Get PDF
    In the contemporary world, oceans are increasingly realized as ‘threatened places’ in need of environmental protection, at risk from pollution, habitat loss, and overfishing. On the other hand, nations around the world are turning their attention to oceans as a new source of economic development and growth, seeing them as ‘industrialized spaces’. The concept of integrating Ecosystem-Based Management (EBM) and Marine Spatial Planning (MSP) is a new approach for sustainable Ocean Governance (SOG). As an effective strategic tool for planning and managing conflicting ocean uses and their interactions with marine ecosystems, the EBM-MSP approach creates an opportunity for long-term development in relation to ocean and its resources. This thesis scrutinizes the contemporary concepts, definitions, and approaches pertinent to the establishment of a comprehensive Ecosystem-based Management and Marine Spatial Planning (EBM-MSP) framework for Sustainable Ocean Governance that reflects global and regional standards. The study also analyses various scientific data – especially the pollutants’ concentration at spatial and temporal scales – with special reference to EBM-MSP. The research analyses international laws, declarations, conventions, and agreements that are relevant to the proposition of a new dynamic approach to SOG based on EBM-MSP. This new approach could be useful to support necessary reforms, filling gaps in legal regimes and achieving integrated and effective ocean governance mechanisms to prevent, reduce, and control pollution in the marine environment, as well as promoting sustainable exploration of marine resources. Specifically, the research critically analyses the existing legal frameworks in relation to SOG in the Bay of Bengal (BOB). Based on an analysis of sectoral legislation and institutional arrangements in the BOB, the thesis recommends the modification and adoption of legislation, as well as integration among the relevant departments of Bangladesh Government, to match transboundary SOG, particularly along with EBM-MSP development processes. The study focuses on national policies and strategies along with sectoral legislation and institutional arrangements to contribute towards EBM-MSP at national level for SOG, by considering socioeconomic balance and jurisdictional overlays. Based on experiences in the Baltic Sea, Mediterranean Sea, and Great Barrier Reef Marine Park (GBRMP), the research determines numerous key features to assist with the generation and application of EBM-MSP in the BOB region, specifically in Bangladesh, by integrating EBM-MSP with particular reference to a Comprehensive Ocean Zoning (COZ). The substantial outcome of the study is to suggest a COZ Framework for Bangladesh to protect priority seascapes and sites, species of special concern, and their critical habitats, by designing Marine Protected Area networks throughout the transboundary coast

    Energy Supplies in the Countries from the Visegrad Group

    Get PDF
    The purpose of this Special Issue was to collect and present research results and experiences on energy supply in the Visegrad Group countries. This research considers both macroeconomic and microeconomic aspects. It was important to determine how the V4 countries deal with energy management, how they have undergone or are undergoing energy transformation and in what direction they are heading. The articles concerned aspects of the energy balance in the V4 countries compared to the EU, including the production of renewable energy, as well as changes in its individual sectors (transport and food production). The energy efficiency of low-emission vehicles in public transport and goods deliveries are also discussed, as well as the energy efficiency of farms and energy storage facilities and the impact of the energy sector on the quality of the environment

    TRANSEUNTIS MUNDI, A NOMADIC ARTISTIC PRACTICE

    Get PDF
    In this practice-led Ph.D. research, I investigate how an artistic practice can respond to the migration phenomena performed by human beings across the planet over millennia ¬– what I refer to as the millennial global human journey. Based on the idea of mobility, I chose to frame this research in the articulation of concepts deriving from the prefix trans: transculture, transhumance and transmediality. This research contributes to studies in art composition by developing the processes and concept of transmedial composition, mainly contributing to the field of New Media Art. This investigation resulted in the work Transeuntis Mundi (TM) Project – a nomadic artistic practice that encompasses: the TM Derive and manual, the TM Archive, the TM VR work Derive 01 and two forms for its notation. Transeuntis mundi (TM), from the Latin language, means the ‘passersby of the world’ and metaphorically personify in this work the millennial migrants and their global journeys. Based on proposals from the Realism art movement and the walking-based methodologies of Walkscapes and Dérive, the TM Derive was created as a nomadic methodology of composition in response to the ideas of migration and ancestry. It is framed by the minimal stories ¬– the form of narrative of this work, captured from field recordings with 3D technology of everyday life worldwide. This material formed the TM Archive, presented in the TM VR work. The TM VR work Transeuntis Mundi Derive 01 is an immersive and interactive performative experience for virtual reality, that artistically brings together stories, sounds, images, people, and places worldwide, ¬as a metaphor of the millennial global human migration. This work happens as a VR application using 3D technology with 360º image and ambisonic sound, in order to promote an engaged experience through the immersion and interactivity of the participant. This thesis presents and contextualizes these creations: the scope, references, concepts, origin, collaborations, methodology, technologies, and results of this work. It is informed and accompanied by reflexive and critical writing, including an articulation with references of works across different artistic media and fields.UNIRIO Federal University of the State of Rio de Janeir
