AbstractThis paper will adopt the Munich Agile Concepts (MAGIC) on the design of Vertistops and Vertiports (Verti-X) for Urban Air Mobility (UAM) Systems. Vertiports and Vertistops are single or multi-landing spaces for air taxis, which are electric-powered vertical take-off and landing (eVTOLs) aircraft. The target of this paper is to apply a holistic approach how to design so called Verti-X in a holistic and system of system method from the Requirement-, Function-. Architecture- and the Implementation phase. The MAGIC approach contains all of the requierd phases which are necessary to build up such a complex design of Verti-X. Therefore, based on the literature survey, we have determined the key components of the Verti-X design with a thorough requirement analysis. Then, we have followed the existed criteria and regulations to design a valid and verified Verti-X which fulfills all the requirement. Furthermore, the focus of this paper is to apply the first four phases of MAGIC regarding the requirement, function, architecture and the implementation of such Verti-X Design.

First-hand experiences in several design projects that were based on media richness and collaboration are described in this article. Although complex design processes are merely considered as socio-technical systems, they are deeply involved with natural systems. My collaborative research in the field of performance-oriented design combines digital and physical conceptual sketches, simulations and prototyping. GIGA-mapping - is applied to organise the data. The design process uses the most suitable tools, for the subtasks at hand, and the use of media is mixed according to particular requirements. These tools include digital and physical GIGA-mapping, parametric computer aided design (CAD), digital simulation of analyses, as well as sampling and 1:1 prototyping. Also discussed in this article are the methodologies used in several design projects to strategize these tools and the developments and trends in the tools employed.  The paper argues that the digital tools tend to produce similar results through given pre-sets that often do not correspond to real needs. Thus, there is a significant need for mixed methods including prototyping in the creative design process. Media mixing and cooperation across disciplines is unavoidable in the holistic approach to contemporary design. This includes the consideration of diverse biotic and abiotic agents. I argue that physical and digital GIGA-mapping is a crucial tool to use in coping with this complexity. Furthermore, I propose the integration of physical and digital outputs in one GIGA-map and the participation and co-design of biotic and abiotic agents into one rich design research space, which is resulting in an ever-evolving research-design process-result time-based design.

How can local authorities effectively approach the decarbonisation of urban environments? Recent efforts to redirect cities into a less energy-intensive model have been mostly approached from a sectoral perspective, with specific energy policies and plans being issued without deeply considering their ties with other urban aspects. In this sense, well-established urban planning procedures have not been part of those, with the consequence of barriers in the implementation phase of those energy plans. The Cities4ZERO methodology was developed to guide effective integration between urban planning and energy policies, plans, and practices. It provides a holistic approach to strategic municipal processes for urban decarbonisation in the mid-long term, which includes key local stakeholders’ engagement into integrated energy planning processes, as well as tools for effective energy decarbonisation modelling. This paper analyses the application of the Cities4ZERO decarbonisation methodology on its strategic stage in the development of Vitoria-Gasteiz’s Action Plan for an Integrated Energy Transition 2030 (APIET 2030). It suggests that in order to accelerate urban decarbonisation, it is critical to: (a) foster interdepartmental collaboration; (b) allow for flexibility on the land-use planning regulations; (c) back decisions with detailed urban-energy models; and (d) truly engage key local stakeholders in the planning and implementation processes.

The set of measures to contain the diffusion of COVID-19 instituted by the European governments gave an unparalleled opportunity to improve our understanding of the transport and industrial sectors’ contribution to urban air pollution. The purpose of this study was to assess the impacts of the lockdown measures on air quality and pollutant emissions in Valencia, Spain. For this reason, we determined if there was a significant difference in the concentration levels of different particulate matter (PM) sizes, PM10, PM2.5, and NOx, NO2, NO, and O3, between the period of restrictions in 2020 and the same period in 2019. Our findings indicated that PM pollutant levels during the lockdown period were significantly different from the same period of the previous year, even if there is variability in the different local areas. The highest variations reduction in the PM10 and PM2.5 levels were observed for the València Centre, València Avd Francia, and València Pista de Silla (all of the urban traffic type) in which there was a reduction of 58%–42%, 56%–53%, and 60%–41% respectively. Moreover, consistent with recent studies, we observed a significant reduction in nitric oxide levels in all the air monitoring stations. In all seven monitoring stations, it was observed, in 2020, NOx, NO2, and NO concentrations decreased by 48.5%–49.8%–46.2%, 62.1%–67.4%–45.7%, 37.4%–35.7%–35.3%, 60.7%–67.7%–47.1%, 65.5%–65.8%–63.5%, 60.0%–64.5%–41.3%, and 60.4%–61.6%–52.5%, respectively. Lastly, overall O3 levels decreased during the lockdown period, although this phenomenon was more closely related to weather conditions. Overall, no significant differences were observed between the meteorological conditions in 2019 and 2020. Our findings suggest that further studies on the effect of human activities on air quality are needed and encourage the adoption of a holistic approach to improve urban air quality.

The concept of resilience implies uncertainty and the ability to adapt to unexpected changes. Projects in cities that require long periods of time and extensive budgets, which include large parks, need resilience to flexibly cope with political, economic, social, and physical changes. The concept of resilience emerged from the design of large parks in the early 2000s and has continued in more recent urban design competitions, but there is still a lack of research on specific planning strategies in the literature. This paper aims to interpret the process of creating a large park and to explore the strategies needed for a resilient process by examining the first national urban park being planned in Seoul, Korea as an example. After discussions began in 1990 and the General Basic Plan was established in 2011, the winning design was announced through an international design competition in 2012. Although the park master plan was considered complete as of 2018, its progress seems unclear because of various changes in the surrounding urban planning and political and economic conditions. This study intends to examine the processes that have already been executed and to assist in setting the future direction of the project. Through the framework derived from prior research on the concept of resilience, this project’s process is examined and analyzed in six main categories: park infrastructure, social dynamics, economic dynamics, health and well-being, governance networks, and planning and institutions. The results show that the categories park infrastructure, health and well-being, and planning and institutions are consistent with the resilience planning strategy to some degree, but social dynamics, economic dynamics, and governance networks are unsatisfactory. From a resilience perspective, a holistic approach to designing the process is most important in planning a large park, beginning from the conceptual stage through to the long-term implementation phase. An integrative process should aim to incorporate specialized knowledge and experiences from a variety of fields, not to resolve single aspects in a piecemeal fashion. This study aims to provide a practical link between large-scale park projects and the concept of resilience for the future.

In this chapter, the authors present an applied holistic mathematical model for business transformation (AHMM)-specific implementation for supporting an intelligent strategic decision making system (iSDMS) that is based on the management and evaluation of critical success factors (CSF). The AHMM-based iSDMS is based on a unique mixed research method that is supported by a mainly the author's qualitative research module, where the main goal is to insure long-term strategic business competitive advantage. An adapted AHMM for iSDMSs uses a natural programming language (NLP) environment and CSFs to model iSDMS. The iSDMS is based on a central reasoning engine and a distributed enterprise architecture project's (EAP) paradigm. This chapter's experiment is based on a proof of concept (PoC), which presents a concrete transformation decision making case, where the central point is the transformation of an information system. Such an iSDMS is managed by an iSDMS transformation manager(s) (iSDMSTM); it uses a methodology and a framework that can support and estimate the risks of implementation of an iSDMS and then uses it to solve problems. The iSDMSTM is responsible for the implementation of the complex iSDMSs, where during its implementation phase, the chosen transformation framework supports the iSDMSTM in a just-in-time manner. The “I” or “i” prefix does not stand just for the vulgare urban and siloed business and technical environments but for a distributed and holistic approach to transform complex business and technical systems.

Abstract In this work, we present and illustrate a holistic approach, the M3-approach (methodologies, models, measures), for efficient and accurate design of Ka-band transmitter modules in earth stations on mobile platforms (ESOMPs) for satellite communication applications. We begin by applying this approach to derive the system specifications, considering the application and international regulatory requirements. Based on these specifications, we derive the system/transmitter architecture, and then specify the components of this architecture. Furthermore, we develop a concept for low-cost realization of the transmitter module, and a concept for testing the module. For the implementation of the realization concept, 3D full-wave electromagnetic-based models are developed at the packaging and component levels. To verify these models, test samples are fabricated and measured. Excellent correlation is obtained between measurement and simulation results. The verified models are applied to optimize the RF performance of the Ka-band transmitter components and modules.

The complexity of adaptive Web applications (AWA) is increasing almost every day. Besides impacting the implementation phase, this complexity must also be suitably managed while modeling the application. To this end, the paper proposes an approach for AWA called GIWA based on WA-UML (Web Adaptive Unified Modeling Language). This extension defines a set of stereotypes and constraints, which make possible the modeling of AWA. GIWA’s target is to facilitate the automatic execution of the design and the automatic generation of adaptable web interface. The GIWA methodology is based on different step: requirement analysis, conceptual design, adaptation design and generation. Using GIWA, designers can specify, at a requirement analysis, the features of web application to be generated. These features are represented, at the conceptual level using WA-UML. At the adaptation level, GIWA acquires all information about users’ preferences and their access condition to be used at the generation level. The last level is based on java swing interface to instantiate models which are translated in XML files. GIWA uses then XSL files (user preferences) and RDF files (devices’ capability) to generate the HTML page corresponding to the user.
