Technology in Life
2016
Technological advancements have changed human life throughout history as technical inventions have emancipated people from many mundane, necessary tasks. The development of technical artefacts has long relied on the natural sciences and engineering. However, recent technical advancements—such as ubiquitous and multifunctional technologies as well as the emergence of social media—have made it necessary to approach design from a multidisciplinary perspective and to ground design thinking more on the understanding of human mind and human life. As the natural sciences and human research are in many respects different practices, it is time to discuss their mutually inclusive roles in design and …
Instrumentation, control, and automation for submerged anaerobic membrane bioreactors
2015
A submerged anaerobic membrane bioreactor (AnMBR) demonstration plant with two commercial hollow-fibre ultrafiltration systems (PURON® , Koch Membrane Systems, PUR-PSH31) was designed and operated for urban wastewater treatment. An instrumentation, control, and automation (ICA) system was designed and implemented for proper process performance. Several single-input-single-output (SISO) feedback control loops based on conventional on off and PID algorithms were implemented to control the following operating variables: flow-rates (influent, permeate, sludge recycling and wasting, and recycled biogas through both reactor and membrane tanks), sludge wasting volume, temperature, transmembrane pr…
Experimental and Numerical Analysis of a Cross-Flow Turbine
2016
An important component of the management cost of aqueducts is the energy costs. Part of these costs can be recovered by transforming some of the many existing energy dissipations into electric energy by means of economical turbines. This paper describes an experimental study that has been carried out in order to (1) test the performance of an economical cross-flow turbine that maintains high efficiency within a large range of water discharges, and (2) validate a new approximate formula relating main inlet velocity to inlet pressure. It is demonstrated that the proposed formula, on the basis of some simplifying assumptions, exactly links inlet velocity to inlet pressure with any possible geo…
Effective digital collaboration in the construction industry – A case study of BIM deployment in a hospital construction project
2015
We examine a case of successful integrated BIM-based design in a construction project.We present a set of key factors influential to enable digital collaboration in this project.Key factors identified include: change agents, new roles, cloud computing, contracts, etc.We found integrated design to depend upon changing traditional work practices.The case is an example of BIM implementation and collaborative work in the AEC industry. Building information modeling (BIM) and related digital innovations can serve as a catalyst for more transparency, tighter integration, and increased productivity in the architecture, engineering, and construction industry. Yet, many project teams struggle with ho…
Presenting a Multi-level Superstructure Optimization Approach for Mechatronic System Design
2010
Synergism and integration in the design process is what sets apart a Mechatronic System from a traditional, multidisciplinary system. However the typical design approach has been to divide the design problem into sub problems for each technology area (mechanics, electronics and control) and describe the interface between the technologies, whereas the lack of well-established, systematic engineering methods to form the basic set-off in analysis and design of complete mechatronic systems has been obvious. The focus of the current paper is therefore to present an integrated design approach for mechatronic system design, utilizing a multi-level superstructure optimization based approach. Finall…
Wideband modeling of cascaded H-plane waveguide junctions using the generalised impedance matrix representation
2009
A strong interest in H-plane waveguide components composed of a large number of cascaded planar junctions is recently renewed. Therefore, the more efficient development of full-wave analysis tools of such devices is again receiving consideration, specially for its potential use within modern design tools. A novel technique for providing the wideband generalised impedance matrix representation of the inductive devices in the form of pole expansions, thus extracting the most expensive computations from the frequency loop is proposed. For such purpose, the whole device is first decomposed into simpler building blocks, i.e. planar junctions and uniform waveguides, which are modelled in terms of…
Designing for Networked Community Resilience
2016
Abstract Communities have been described to be at the heart of the preparedness for and the response to disasters. The increasing connectedness has made communities more vulnerable for their dependence on a complex network of critical infrastructures. At the same time, this very connectedness has the potential to enable communities to self-organise, engage, and connect with other communities to improve their resilience. While the pathway to more resilience is promising and has many advocates, the response to crises and disasters, time and again reveals the challenges related to (i) ad-hoc switching from preparedness to response; (ii) ad-hoc connecting professional responders, communities, v…
How is Building Information Modeling Influenced by Project Complexity?
2014
Virtual design and construction of buildings and architectural spaces require extensive collaboration among a diverse set of design professionals. The authors analyze e-collaboration performance in two construction projects of differing complexity, to gain an understanding of how collaborative design based on building information modeling (BIM) is influenced by the complexity of the building project. The findings suggest that the perceived business value of BIM depends on project complexity and that BIM-based collaboration does not yield unconditional positive implications for all types of construction projects. The authors argue that current practice would benefit from a more structured ap…
Industrial development as discursive change: A case of symbiotic learning
2016
The Eyde Cluster is a network of companies at Agder seeking to enhance sustainabledevelopment through vocational training. A dialogical approach is taken to developing anew discourse, using principles of communicative organisational change. There isdiscussion of a more bottom up approach, in line with Workplace Innovation. The paperargues for balancing formal education and vocational training in a way that createssymbiotic learning.
Innovation in collaborative design: an exploratory study in hackathon
2021
International audience; Collaborative design is the use of design practices which tend to favor the integration of different experts, and to support creativity and innovation. Therefore, in this study, we were particularly interested in the collaborative design tools used in the specific context of a pedagogical hackathon. During this event, 1310 engineering students mentored by professors and industrial experts worked on around 131 industrial projects. In this article, we will present our study of the tools put in place by the participants of these innovative projects according to their training. Our study is based on a collection of project data. We will show that storyboards are often us…
