    This thesis presents a coherent, sustained and substantial contribution to the advancement of knowledge or application of knowledge or both in the field of construction management and economics. More specifically, this thesis outlines the strategic development of the built environment through lessons from international construction, quality and productivity management. The strategic role of construction in economic development is emphasized. It describes the contributions transnational construction firms made towards modern-day construction project management practices globally. It establishes the relationship between construction quality and economic development and fosters a better understanding of total quality management and quality management systems in enhancing construction industry performance. Additionally, it prescribes lessons from the manufacturing industry for construction productivity and identifies the amount of carbon emissions reduced through lean construction management practices to alleviate the generally adverse effects of the built environment on global climate change. It highlights the need for integrated management systems to enhance quality and productivity for sustainable development in the built environment. The thesis is an account of how the built environment has evolved, leveraging on lessons from international construction, quality and productivity management for improvements over the past two decades

    [2022 International Conference for ADADA + CUMULUS] 26 - 27 November 2022, OnlineArt has been at the center of human spiritual life, and therefore, art in the future space age is an exciting subject. The authors, led by an artist, have been creating video artwork "Sound of Ikebana, " made by giving sound vibration to fluid and shooting it with a high-speed camera. To study its shape under zero gravity, we conducted the generation of the artwork under microgravity realized by parabolic flight. As the sound source, we used the birth cries of newborn babies, which also symbolize the future. We confirmed that a new shape that has never existed is created. Furthermore, a three-dimensional artwork was created by shooting the phenomenon from multiple viewpoints

    Understanding user experience of mobile video: Framework, measurement, and optimization

    Since users have become the focus of product/service design in last decade, the term User eXperience (UX) has been frequently used in the field of Human-Computer-Interaction (HCI). Research on UX facilitates a better understanding of the various aspects of the user’s interaction with the product or service. Mobile video, as a new and promising service and research field, has attracted great attention. Due to the significance of UX in the success of mobile video (Jordan, 2002), many researchers have centered on this area, examining users’ expectations, motivations, requirements, and usage context. As a result, many influencing factors have been explored (Buchinger, Kriglstein, Brandt & Hlavacs, 2011; Buchinger, Kriglstein & Hlavacs, 2009). However, a general framework for specific mobile video service is lacking for structuring such a great number of factors. To measure user experience of multimedia services such as mobile video, quality of experience (QoE) has recently become a prominent concept. In contrast to the traditionally used concept quality of service (QoS), QoE not only involves objectively measuring the delivered service but also takes into account user’s needs and desires when using the service, emphasizing the user’s overall acceptability on the service. Many QoE metrics are able to estimate the user perceived quality or acceptability of mobile video, but may be not enough accurate for the overall UX prediction due to the complexity of UX. Only a few frameworks of QoE have addressed more aspects of UX for mobile multimedia applications but need be transformed into practical measures. The challenge of optimizing UX remains adaptations to the resource constrains (e.g., network conditions, mobile device capabilities, and heterogeneous usage contexts) as well as meeting complicated user requirements (e.g., usage purposes and personal preferences). In this chapter, we investigate the existing important UX frameworks, compare their similarities and discuss some important features that fit in the mobile video service. Based on the previous research, we propose a simple UX framework for mobile video application by mapping a variety of influencing factors of UX upon a typical mobile video delivery system. Each component and its factors are explored with comprehensive literature reviews. The proposed framework may benefit in user-centred design of mobile video through taking a complete consideration of UX influences and in improvement of mobile videoservice quality by adjusting the values of certain factors to produce a positive user experience. It may also facilitate relative research in the way of locating important issues to study, clarifying research scopes, and setting up proper study procedures. We then review a great deal of research on UX measurement, including QoE metrics and QoE frameworks of mobile multimedia. Finally, we discuss how to achieve an optimal quality of user experience by focusing on the issues of various aspects of UX of mobile video. In the conclusion, we suggest some open issues for future study

    Paraiso : An Automated Tuning Framework for Explicit Solvers of Partial Differential Equations

    Full text link
    We propose Paraiso, a domain specific language embedded in functional programming language Haskell, for automated tuning of explicit solvers of partial differential equations (PDEs) on GPUs as well as multicore CPUs. In Paraiso, one can describe PDE solving algorithms succinctly using tensor equations notation. Hydrodynamic properties, interpolation methods and other building blocks are described in abstract, modular, re-usable and combinable forms, which lets us generate versatile solvers from little set of Paraiso source codes. We demonstrate Paraiso by implementing a compressive hydrodynamics solver. A single source code less than 500 lines can be used to generate solvers of arbitrary dimensions, for both multicore CPUs and GPUs. We demonstrate both manual annotation based tuning and evolutionary computing based automated tuning of the program.Comment: 52 pages, 14 figures, accepted for publications in Computational Science and Discover

    An overview of Digital Lexicography and directions for its future: An interview with Gilles-Maurice de Schryver

    Get PDF
    In this contribution Rove Chishman and Bruna da Silva present questions to the President of the European Association for Lexicography, Gilles-Maurice de Schryver. In answering, G-M de Schryver calls a spade a spade: No, there is no theory of lexicography, but yes, there is a future for lexicographers. For that future to be bright, lexicographers will have to join hands with the Big Data companies, and accept that their invaluable input will be all but invisible to the users. Artificial Intelligence components will have to be used in earnest, so that ‘searches’ (not look-ups!) will instantly lead to context-sensitive answers. Browsing lexical data only starts from these answers and proceeds from there in two- (and why not three-) dimensional multimedia spaces. To achieve this, G-M de Schryver points to the most promising research ideas at present, as well as the top teams involved in digital dictionary user research.Keywords: EURALEX; eLex; digital lexicography; e-dictionaries; corpora; automation; crowdsourcing; Corpus Query Packages (CQPs); Dictionary Writing Systems (DWSs); artificial intelligence (AI); user-friendliness; mobile devices; augmented writing assistants; eye-tracking; digital user research
