In the era of Industry 4.0, data has become a critical driver of innovation and competitiveness in manufacturing. The up-take of technologies such as IoT, AI, and robotics has led to an unprecedented explosion of data, offering transformative opportunities for process optimization, product quality enhancement, predictive maintenance, and customisation. However, realizing these benefits requires effective data collection, storage, and processing, which necessitates robust and adaptable IT infrastructures. This white paper provides a comprehensive overview of four popular data infrastructure paradigms: data lakes, data fabrics, data meshes, and data spaces. Each of these paradigms have their unique focus points and application domains. Metadata serves as a crucial component, enhancing the findability, accessibility, interoperability, and reusability of data. The paper also explores critical building blocks of modern data infrastructures within manufacturing environments, such as OPC UA, brokers, and data catalogues, highlighting their role in enabling effective data sharing, management, and governance.

This book is a journey through coexisting, emerging or speculated about, types of digital value transfer infrastructures. Using digital value transfer infrastructures as a central case study, this thesis is concerned with unpacking the negotiation processes that shape the governance, design and political purposes of digital infrastructures that are closely linked to the public interest and state sovereignty. In particular, the papers that are assembled in this manuscript identify and inspect three main socio-technical developments occurring in the domain of value transfer technologies: a) the privatization and platformization of digital payment infrastructures; b) the spread of blockchain-based digital value transfer infrastructures; c) the construction of digital value transfer infrastructures as public utilities, from the part of public institutions or organizations. Concerned with the relationship between law, discourse and technological development, the thesis explores four transversal issues that strike differences and peculiarities of these three scenarios: i) privacy; ii) the synergy and mutual influence of legal change and technological development in the construction of digital infrastructures; iii) the role of socio-technical imaginaries in policy-making concerned with digital infrastructures; iv) the geography and scale of digital infrastructures. The analyses lead to the argument that, in the co-development of legal systems and digital infrastructures that are core to public life, conflicts are productive. Negotiations, ruptures and exceptions are constitutive of the unending process of mutual reinforcement, and mutual containment, in which a plurality of agencies – expressed through legal institutions, symbolic systems, as well as information and media structures – are entangled.

Climate change and changing land use challenge the livability and flood safety of Dutch cities. One option cities have to become more climate-proof is to increase infiltration of stormwater into soil through permeable pavement and thus reduce discharge of stormwater into sewer systems. To analyze the market receptivity for permeable pavements in the Netherlands, this article focuses on the perception of end-users towards key transition factors in the infrastructure transformation processes. Market receptivity was studied on two levels: (1) on the system level, by analyzing 20 key factors in the Dutch urban water sector that enable wider application of permeable pavements; and (2) on the technology level, by analyzing 12 key factors that explain why decision makers select permeable pavements or not. Results show that trust between cooperating partners was perceived as the system level key factor that needs to be improved most to facilitate the wider uptake of permeable pavements. Additionally, the association of end-users with permeable pavement, particularly their willingness to apply these technologies and their understanding of what kinds of benefits these technologies could bring, was regarded the most important receptivity attribute. On the technology level, the reliability of permeable pavement was regarded as the most important end-user consideration for selecting this technology.

This book analyses the values and processes that characterise DIY (do it yourself) digital infrastructure, relating networked initiatives to broader tensions in contemporary alternative media production, namely between ideology and practice in cultural and artistic networked initiatives. Adopting immersive and direct engagement methods, focusing specifcially on the case of A Traversal Network of Feminist Servers, this book shows that contemporary alternative media projects are defined mainly by the people and the networks they build — alternative infrastructures are about the process driving them, more so than the content produced. Small or local organisations intervene in infrastructures by building responses to extractivist platform models, but can be exclusive to the communities already involved in the process. Nevertheless, alternative media initiatives are culturally and socially significant, as they produce critical media discourses and network imaginaries that signify a call for better digital and technical literacy in society.

The ‘Grand Challenges’ of our times, like climate change, resource depletion, global inequity, and the destruction of wildlife and biodiversity can only be addressed by innovating cities. Despite the options of tele-working, tele-trading and tele-amusing, that allow people to participate in ever more activities, wherever they are, people are resettling in cities at an unprecedented speed. The forecasted ‘rurification’ of society did not occur. Technological development has drained rural society from its main source of income, agriculture, as only a marginal fraction of the labour force is employed in agriculture in the rich parts of the world. Moreover, technological innovation created new jobs in the IT and service sectors in cities. Cities are potentially far more resource efficient than rural areas. In a city transport distances are shorter, infrastructures can be applied to provide for essential services in a more efficient way and symbiosis might be developed between various infrastructures. However, in practice, urban infrastructures are not more efficient than rural infrastructures. This paper explores the reasons why. It digs into the reasons why the symbiotic options that are available in cities are not (sufficiently) utilised. The main reason for this is not of an economic nature: Infrastructure organisations are run by experts who are part of a strong paradigmatic community. Dependence on other organisations is regarded as limiting the infrastructure organisation’s freedom of action to achieve its own goals. Expert cultures are transferred in education, professional associations, and institutional arrangements. By 3 concrete examples of urban systems, the paper will analyse how various paradigms of experts co-evolved with evolving systems. The paper reflects on recent studies that identified professional education as the initiation into such expert paradigms. It will thereby relate lack of urban innovation to the monodisciplinary education of experts and the strong institutionalised character of expertise. https://doi.org/10.1007/978-3-319-63007-6_43 LinkedIn: https://www.linkedin.com/in/karelmulder/

Biogas is produced from biomass by means of digestion. Treated to so-called ‘green gas’, it can replace natural gas. Alternatively, biogas can be used to produce electrical power and heat in a combined heat power (CHP) installation. In 2014 global biogas production was only 1% of natural gas production. In the future, biogas is expected to play a role in specific applications, e.g. to provide flexibility in electricity supply

The volume of biogas produced in agricultural areas is expected to increase in coming years. An increasing number of local and regional initiatives show a growing interest in decentralized energy production, wherein biogas can play a role. Biogas transport from production sites to user, i.e. a CHP, boiler or an upgrading installation, induces a scale advantage and an efficiency increase. Therefore the exploration of the costs and energy use of biogas transport using a dedicated infrastructure is needed. A model was developed to describe a regional biogas grid that is used to collect biogas from several digesters and deliver it to a central point. The model minimizes transport costs per volumetric unit of biogas in a region. Results are presented for different digester scales, different sizes of the biomass source area and two types of grid lay-out: a star lay-out and a fishbone lay-out. The model shows that transport costs in a fishbone lay-out are less than 10 Vct m3 for a digester scale of 100 m3 h1; for the star lay-outcosts can go up to 45 Vct m3. For 1800 m3 h1 digesters, these values are 4.0 Vct m3 and 6.1 Vct m3, respectively. The results indicate that cooperation between biogas producers in collecting biogas by means of a fishbone lay-out reduces the biogas transport costs relative to using a star lay-out. Merging smaller digesters into a smaller number of larger ones reduces the costs of biogas transport for the same biomass source area.
