    Integrated Approaches to Digital-enabled Design for Manufacture and Assembly: A Modularity Perspective and Case Study of Huoshenshan Hospital in Wuhan, China

    Get PDF
    Countries are trying to expand their healthcare capacity through advanced construction, modular innovation, digital technologies and integrated design approaches such as Design for Manufacture and Assembly (DfMA). Within the context of China, there is a need for stronger implementation of digital technologies and DfMA, as well as a knowledge gap regarding how digital-enabled DfMA is implemented. More critically, an integrated approach is needed in addition to DfMA guidelines and digital-enabled approaches. For this research, a mixed method was used. Questionnaires defined the context of Huoshenshan Hospital, namely the healthcare construction in China. Then, Huoshenshan Hospital provided a case study of the first emergency hospital which addressed the uncertainty of COVID-19. This extreme project, a 1,000-bed hospital built in 10 days, implemented DfMA in healthcare construction and provides an opportunity to examine the use of modularity. A workshop with a design institution provided basic facts and insight into past practice and was followed by interviews with 18 designers, from various design disciplines, who were involved in the project. Finally, multiple archival materials were used as secondary data sources. It was found that complexity hinders building systems integration, while reinforcement relationships between multiple dimensions of modularity (across organisation-process-product-supply chain dimensions) are the underlying mechanism that allows for the reduction of complexity and the integration of building systems. Promoting integrated approaches to DfMA relies on adjusting and coupling multi-dimensional modular reinforcement relationships (namely, relationships of modular alignment, modular complement, and modular incentive). Thus, the building systems integrator can use these three approaches to increase the success of digital-enabled DfMA

    Resilient and Scalable Forwarding for Software-Defined Networks with P4-Programmable Switches

    Get PDF
    Traditional networking devices support only fixed features and limited configurability. Network softwarization leverages programmable software and hardware platforms to remove those limitations. In this context the concept of programmable data planes allows directly to program the packet processing pipeline of networking devices and create custom control plane algorithms. This flexibility enables the design of novel networking mechanisms where the status quo struggles to meet high demands of next-generation networks like 5G, Internet of Things, cloud computing, and industry 4.0. P4 is the most popular technology to implement programmable data planes. However, programmable data planes, and in particular, the P4 technology, emerged only recently. Thus, P4 support for some well-established networking concepts is still lacking and several issues remain unsolved due to the different characteristics of programmable data planes in comparison to traditional networking. The research of this thesis focuses on two open issues of programmable data planes. First, it develops resilient and efficient forwarding mechanisms for the P4 data plane as there are no satisfying state of the art best practices yet. Second, it enables BIER in high-performance P4 data planes. BIER is a novel, scalable, and efficient transport mechanism for IP multicast traffic which has only very limited support of high-performance forwarding platforms yet. The main results of this thesis are published as 8 peer-reviewed and one post-publication peer-reviewed publication. The results cover the development of suitable resilience mechanisms for P4 data planes, the development and implementation of resilient BIER forwarding in P4, and the extensive evaluations of all developed and implemented mechanisms. Furthermore, the results contain a comprehensive P4 literature study. Two more peer-reviewed papers contain additional content that is not directly related to the main results. They implement congestion avoidance mechanisms in P4 and develop a scheduling concept to find cost-optimized load schedules based on day-ahead forecasts

    Out of sight, out of mind: accessibility for people with hidden disabilities in museums and heritage sites

    Get PDF
    As of 2020, an estimated 14.1 million residents of the United Kingdom reported a disability (DWP 2020). Within this population, approximately 6.1 million people have a hidden disability (Buhalis and Michopoulou 2011). These hidden disabilities range widely, from neurodiverse conditions like autism and dyslexia to long term chronic conditions such as fibromyalgia and arthritis. Due to the wide range of disabilities and their impact on a disabled person’s life, they have generally been underrepresented in accessibility studies. This thesis uncovers the accessibility needs of people with hidden disabilities, specifically in museums and heritage sites where they have heretofore mostly been overlooked. I utilise semi-structured interviews and correspondence with people with hidden disabilities, as well as participant-led experiences through three case study sites in Northern England, to understand the barriers they face. Their experiences help me expose the importance of passive accessibility – accessibility measures built directly into an exhibition design, such as adequate lighting and personal interpretation boards. Additionally, this thesis aims to understand the cultural forces that prevent or support accessibility-related improvements to such sites from taking place. By studying the cultural make-up of each case study organisation through ethnographic observations of the staff at these sites, institutional roadblocks to enacting accessibility-related adjustments are revealed. Specifically, the lack of communication at these sites presents a significant barrier to enacting accessibility suggestions from disabled visitors. Tying together the themes of active/passive accessibility and lack of communication is the theme of gaps in disability awareness, by which I mean that heritage organisations do not wilfully create these barriers to inclusion, and yet they create them still because they simply do not realise these things. Filling these gaps opens up countless possibilities for improving accessibility not only for people with hidden disabilities but for all visitors and staff at museums and heritage sites
