Narrating Shared Futures
Full text linkThis visual essay features students’ projects from the MSc2 design studio ‘Transdiciplinary Encounters: Narrating Shared Futures’ offered at TU Delft Faculty of Architecture in Spring of 2022, which served as an inspiration for this issue of Footprint. Designed and taught by the issue editors, Aleksandar Staničić and Angeliki Sioli, the course combined cultural heritage and literary narratives to ask students: How can places of memory be rethought using literary techniques, so that they provide the ground for new meanings to emerge and get shared across different cultures? Seven visionary architectural projects featured in this essay, offered their responses to this pertinent question that is fundamental for narrating, imagining and, ultimately, creating shared futures
The Technopolitics of \u27Urban Water\u27 in Colonial India: A Case Study of Hesaraghatta Water Works in Bangalore
No full textThis paper employs the analytical framework of Technopolitics to engage in a nuanced examination of the Hesaraghatta Water Works project, a notable infrastructure initiative in the late nineteenth and early twentieth century colonial Bangalore. In place of ascribing mere scientific import to this water supply system, our inquiry discerns its pivotal role in the establishment of a distinctive technopolitical regime. This transformative regime is notably characterized by the realignment of power dynamics inherent to water governance, stringent regulatory oversight over urban space and its denizens, and the emergence of previously unexplored facets of urban inequalities. By comprehensively mapping the societal and political repercussions of the Hesaraghatta project, we argue that it introduced a novel and far-reaching technopolitical construct – ‘Urban Water’. This construct, far from being a mere hydrological abstraction, significantly reframed collective conceptualizations of water in the urban context and offered a fertile terrain for the exercise of intricate political and governmental rationality inherent to colonial rule. Our meticulous examination of the Hesaraghatta initiative, situated among several concurrent infrastructural endeavors by the colonial government in India\u27s burgeoning cities, elucidates a pivotal ‘technopolitical turn’ characterizing the colonial regime during the early twentieth century
Modernization from Road-building and Transport Planning: The Modern Hankow British Concession
Full text linkThe urban spatial structure of the modern Hankow British Concession is vastly different from that of the adjoining Old Town. Its mode of urban planning and construction had a profound impact on the modern transformation and urban development of modern Wuhan. Previous studies have discussed the concepts of Roadism with Guangzhou as an example, but there is insufficient knowledge related to other treaty ports cities in modern China. This study uses the research methodology of urban morphology to analyse historical evidence from primary archives to investigate the "top-down" process of road-building and transport planning in the Hankow British Concession. As also, the paper discusses the evolution of road networks, block plots and architectural spaces in the Concession under the influence of the construction administration system. Road-building and transport planning was the main way in which the British colonial authorities organised the basic framework of the spatial form of the Concession, as well as an important means of governing the social space and improving the lives of the residents. The construction and development process of the road system in the Concession implies the causes, explicit characteristics and hidden order of the modern development of Hankow and Wuhan city in modern times
Directional Spectrum Estimation for Sea States Generated by the Single Summation Method
Full text linkThe influence of directional spreading of waves is significant for wave-induced loads, wave breaking and nonlinearity of the waves. For physical model testing performed at test facilities such as the Ocean and Coastal Engineering Laboratory at Aalborg University, it is crucial to validate if the test conditions match the target sea states by measurement and analysis of the generated directional wave field. Most of the existing methods assumes a double summation sea state to be present which is valid in the prototype. However, waves in the laboratory are usually generated by single summation. The current paper presents a method to analyse short-crested waves generated by the single summation method. Compared to similar methods oblique reflections are considered instead of only in-line reflections. The results show that the method successfully decomposes the incident and reflected wave fields in the time domain. Thus, for example the incident wave height distribution may be obtained. The sensitivity of the new method to additional reflective directions, noise, calibration errors and positional errors of the wave gauges was found small
Strategic decision-making in process optimization of healthcare technology manufacturing
Full text linkThe dynamic nature of the healthcare technology industry necessitates constant improvement and optimization of supply chain processes to maintain competitiveness. Manufacturing unit processes, as critical components of the supply chain, directly influence production efficiency, lead times, and overall supply chain performance. Therefore, a strategic focus on optimizing these processes can significantly enhance the responsiveness and cost-effectiveness of the entire supply chain. However, for large enterprises, determining the unit where optimization will be implemented is intricate, considering the multifaceted nature of the decision-making process. The complexity arises from the presence of diverse criteria, each assigned varying importance levels, along with multiple alternative stages to consider. This paper introduces a decision-making framework tailored for such complexities, employing a synergistic blend of two multi-criteria decision-making methods: Best Worst Method (BWM) and ELECTRE III. The application of the proposed framework is demonstrated through a practical case study involving a prominent healthcare technology company, Philips. First, six experts are carefully selected and interviewed to provide a set of criteria with their respective importance weights. Then, using this information, eight alternative processes within the manufacturing unit are ranked using ELECTRE III. The analysis results reveal that process complexity is the top priority for decision-makers when deciding which manufacturing units require optimization first. The findings delve into the intricacies of optimizing production processes in large health technology companies and offer practical solutions and further recommendations
The role of data visibility in the control and automation of modern supply chains - A model predictive control case study in Ferrari
Full text linkNowadays, many companies still conceive their logistic operations as a simple material replenishment of production plants and don’t invest money to structure their supply chain and make processes more efficient. In addition, the high complexity and the emerging uncertainties that are characterizing a more globalized, dynamic, and interconnected world stimulate businesses to innovate the management of their supplier network. Unexpected events, such as COVID-19 and the semiconductor crisis, have put companies in research for solutions that look to improve and strengthen the partnership with their suppliers. Digitization represents one of the most innovative and disruptive challenges in today’s supply chains. Indeed, the increasing amount of data retrievable from logistic and production processes today is yet not exploited enough in comparison with its potential benefits. Companies still work by silos and prefer to hide their information rather than sharing them with their partners. This research investigates the role of data visibility, in order to demonstrate its benefits in a complex supply chain. By collaborating with Ferrari on a Supplier Relationship Management (SRM) project, this paper presents the design of a supply chain control tower through Model Predictive Control. By simulating a Model Predictive Control (MPC) optimization model on a small part of Ferrari’s supplier network, the coordination, efficiency, and sustainability of the supply chain are assessed through a comparison with the current state and by evaluating the network’s performances in different logistic scenarios. Although this solution is presented as a decision-support tool, it is thought of as a key technology for the future development of autonomous supply chain operations
Short-term effects of a summer flash flood on the physiochemical water quality in a restored river
Full text linkIn summer 2021, a flash flood impacted a recently restored river valley in Belgium. Given the anticipated increased frequency and severity of summer flash floods due to climate change, it is imperative to understand their repercussions on aquatic ecosystems. Historical river alterations and nutrient pollution have diminished self-purification, posing significant water quality challenges. This research investigates the effects of a summer flash flood on water quality, with a specific focus on dissolved oxygen, dissolved-, and bound nutrients. Additionally, it evaluates the role of two recently restored meander sections, emphasizing the importance of river restoration projects in enhancing the resilience of the river system. Throughout the summer of the flash flood event, regular water samples were collected, and continuous measurements were conducted. The results revealed that the majority of parameters significantly exceeded the values observed during previous, normal, summers. The considerable influx of organic matter induced anoxic conditions that persisted for approximately a week. For most water quality parameters, more than nine weeks were required for complete recovery post-flash flood. The meanders exhibited a slight improvement of several water quality parameters, induced mostly by the deposition of particles. Near-natural restoration of meanders appeared important. It is probable that the meanders necessitate additional time since reconnection to reach their full potential regarding the enhancement of water quality
The Ethics of Developing, Implementing, and Using Advanced Warehouse Technologies: Top-Down Principles Versus The Guidance Ethics Approach
Full text linkAdvanced technologies are increasingly being utilised in logistics warehouses, raising ethical concerns about responsible development, implementation, and use. In this study, we follow Verbeek\u27s guidance ethics approach to explore the potential positive and negative effects of advanced technologies on the quality of work and values considered important by key stakeholders. This bottom-up approach led us to conduct 23 interviews with engineers, technology advisors, employees with managerial tasks, and operators who are designing, implementing, and/or using advanced technologies. We identified nine categories of technology effects on society, warehousing companies’ business, and operators’ work (i.e., economic, health, opportunities for development, job autonomy, technical complexity, employee voice in technology implementation, job (in)security, privacy, and societal effects). However, limitations were observed in relying on this bottom-up approach, as most stakeholders displayed minimal reflection on ethics and did not formulate their responses in terms of values. To address this, we propose a combination of top-down ethical guidelines and this bottom-up approach, which is essential for evaluating and justifying decision-making throughout the development, implementation, and use of advanced technologies. By combining bottom-up stakeholder engagement and top-down ethical considerations, a more holistic approach to the ethical integration of advanced technologies in logistics warehouses can be achieved
Observing the Telepresent: The school absent child and mediating technologies
Full text linkThe use of telepresence avatars in schools, to facilitate attendance among persistently absent pupils, is increasingly common worldwide. Despite its prevalence, research on this topic lacks theoretical development. This article addresses such a potential gap by employing poststructural, new materialist, and postphenomenological theoretical frameworks to explore analytical potentials in combining insights from all three. To further situate this exploration, an empirical case-example is employed throughout. Through diffractive readings, the article navigates concepts such as intra-action and mediation, to provide nuanced understandings of the dynamics between humans and technology as well as humans through technology.
By integrating postphenomenological perspectives on mediation and new materialist notions of intra-action, it offers insights into the intricate relationships between pupils, telepresence avatars, and social, educational environments. The article explores how researchers might better conceptualize some of the complexities of human-technology interactions, by engaging with diverse theoretical perspectives, paving the way for more informed and ethically grounded research practices in the field of educational technology in general.
Lastly, by integrating these theoretical frameworks diffractively, this article attempts to uncover some of the complex and heterogeneous interplay between human subjects and mediating technologies, while at the same time pointing towards future platforms for further exploration
