    Beam scanning by liquid-crystal biasing in a modified SIW structure

    Get PDF
    A fixed-frequency beam-scanning 1D antenna based on Liquid Crystals (LCs) is designed for application in 2D scanning with lateral alignment. The 2D array environment imposes full decoupling of adjacent 1D antennas, which often conflicts with the LC requirement of DC biasing: the proposed design accommodates both. The LC medium is placed inside a Substrate Integrated Waveguide (SIW) modified to work as a Groove Gap Waveguide, with radiating slots etched on the upper broad wall, that radiates as a Leaky-Wave Antenna (LWA). This allows effective application of the DC bias voltage needed for tuning the LCs. At the same time, the RF field remains laterally confined, enabling the possibility to lay several antennas in parallel and achieve 2D beam scanning. The design is validated by simulation employing the actual properties of a commercial LC medium

    Reinterpreting English Chinoiserie From A Postcolonial And Personal/Taiwanese Perspective: Creating New Narratives Through Art Practice

    Get PDF
    This PhD investigates how to reinterpret English chinoiserie from a postcolonial and personal/Taiwanese perspective through art practice. I explore aspects of history to scrutinise British/European receptions of China and Chineseness as a visual language in eighteenth-century English chinoiserie. This leads me to investigate eighteenth-century Sino-British/East-Europe historiographies to interrogate how to review relevant pre-colonial Sino-British contact. I also review Chineseness as an identity in relation to Taiwanese history, diaspora and my art practice. My findings reject a uniform insider Chineseness and instead point to plurality and subjectivity. That is multiple and personal perspectives from which to revisit history – which informs my approach in which to respond to chinoiserie. I create notional interlocution, a new postcolonial strategy of fictional (auto)ethnography, through contextualising concepts of constructivism, poststructualism, art-based research, and aspects of postcolonial theory. Via this new methodological framework, I make three artist films regarding the chinoiserie collections at the three chosen cultural heritage sites: This is China… explores the chinoiserie interior at the Royal Pavilion Brighton; Another beautiful dream investigates the Chinese wallpaper at Harewood House; and A note on Delftware interrogates the Delftware vases at Chatsworth House. My films are open-ended, yet critical and philosophical, and create new spaces in which to revisit chinoiserie. The films form a trilogy for their shared exploration of English chinoiserie but can be considered independently and seen as independent works

    Technologies and Applications for Big Data Value

    Get PDF
    This open access book explores cutting-edge solutions and best practices for big data and data-driven AI applications for the data-driven economy. It provides the reader with a basis for understanding how technical issues can be overcome to offer real-world solutions to major industrial areas. The book starts with an introductory chapter that provides an overview of the book by positioning the following chapters in terms of their contributions to technology frameworks which are key elements of the Big Data Value Public-Private Partnership and the upcoming Partnership on AI, Data and Robotics. The remainder of the book is then arranged in two parts. The first part “Technologies and Methods” contains horizontal contributions of technologies and methods that enable data value chains to be applied in any sector. The second part “Processes and Applications” details experience reports and lessons from using big data and data-driven approaches in processes and applications. Its chapters are co-authored with industry experts and cover domains including health, law, finance, retail, manufacturing, mobility, and smart cities. Contributions emanate from the Big Data Value Public-Private Partnership and the Big Data Value Association, which have acted as the European data community's nucleus to bring together businesses with leading researchers to harness the value of data to benefit society, business, science, and industry. The book is of interest to two primary audiences, first, undergraduate and postgraduate students and researchers in various fields, including big data, data science, data engineering, and machine learning and AI. Second, practitioners and industry experts engaged in data-driven systems, software design and deployment projects who are interested in employing these advanced methods to address real-world problems

    Thermal-Hydraulics in Nuclear Fusion Technology: R&D and Applications

    Get PDF
    In nuclear fusion technology, thermal-hydraulics is a key discipline employed in the design phase of the systems and components to demonstrate performance, and to ensure the reliability and their efficient and economical operation. ITER is in charge of investigating the transients of the engineering systems; this included safety analysis. The thermal-hydraulics is required for the design and analysis of the cooling and ancillary systems such as the blanket, the divertor, the cryogenic, and the balance of plant systems, as well as the tritium carrier, extraction and recovery systems. This Special Issue collects and documents the recent scientific advancements which include, but are not limited to: thermal-hydraulic analyses of systems and components, including magneto-hydrodynamics; safety investigations of systems and components; numerical models and code development and application; codes coupling methodology; code assessment and validation, including benchmarks; experimental infrastructures design and operation; experimental campaigns and investigations; scaling issue in experiments
