Bangladesh’s energy crisis: A summary of challenges and smart grid-based solutions
No full textSmart grid technologies are an important topic of research and discussion in academia and electrical industries globally. When properly applied, these technologies can enhance the quality, reliability, and availability of electric power while maximizing safety and sustainability. This will both improve economic productivity for industry and quality of life for residents of Bangladesh. Application of smart grid technologies to establish microgrids, based on renewable energy sources as solar and wind power, into the main grid is imperative to ensure the reliability and quality of the electric energy supply to the growing light industries; the driving force of the economic growth for Bangladesh. This paper presents the concurrent condition of energy sector of Bangladesh and discusses the purpose and methods for adopting key smart grid technologies to reach the target put forth by the government of the country in terms of satisfying the demand forecasted in the country's strategic long term plan
Blijft het in Den Haag bij smart city of wordt het smart urbanism?
No full textNormaal gesproken somt men bij smart cities de nieuwste gadgets op. Verbeeldt Siemens haar utopie en promoot men het smart grid als de grote oplossing. Echter, tijdens het ‘Actueel Den Haag Debat’ (ADHD) kwam een interessante tegenstelling bovendrijven. Die leidde tot wat ik maar de Wet van Hajer noem: smart city + lokale politieke keuzes = smart urbanism. Wat gebeurde er?Heritage & DesignTeachers of Practic
How Local Policy Priorities Set the Smart City Agenda
No full textpeer reviewedThe smart city concept has emerged as a key subject pursued by local governments. Yet, it is not clear how policymakers narrow down the topics to focus on with respect to their smart city agenda. As a result, the aim of this paper is to propose a theoretical contribution that explains how local governments define their smart city policy agenda. It is suggested that the agenda is influenced by policy priorities at the local level from other urban domains. To support this notion, policy studies literature is used to show that three streams of problems, policy, and politics, when aligned, set the policy agenda. The smart city agenda will be formed from key ideas existing at the local political level, such as policy priorities, that have now been matched with solutions framed in the smart city context, all underpinned by a favourable political environment. In addition, from smart city policy related documents, a topic modelling analysis illustrates a set of topics that are associated to the smart city policy agenda in two cities, London and Melbourne. This shows how some topics on the smart city agenda can be likened to issues that are the primary topic of another policy domain
Saving Face: Shared experience and dialogue on social touch, in playful smart public space
No full textCan shared experience and dialogue on social touch be orchestrated in playful smart public spaces? In smart city public spaces, in which physical and virtual realities are currently merging, new forms of social connections, interfaces and experiences are be- ing explored. Within art practice, such new connections include new forms of affective social communication with additional social and sensorial connections to enable and enhance empathic, intimate experience in playful smart public space.This chapter explores a novel design for shared intimate experience of playful social touch in three orchestrations of ‘Saving Face’, in different cultural and geographical environments of smart city (semi-) public spaces, in Beijing, Utrecht, Dessau-Berlin. These orchestrations are purposefully designed to create a radically unfamiliar sensory synthesis to disrupt the perception of ‘who sees and who is being seen, who touches and who is being touched’. Participants playfully ‘touch themselves and feel being touched, to connect with others on a screen’. All three orchestrations show that shared experience and dialogue on social touch can be mediated by playful smart cities tech- nologies in public spaces, but rely on design of mediated, intimate and exposed forms of ‘self-touch for social touch’, ambivalent relations, exposure of dialogue and hosting.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.System Engineerin
Impact of Smart Completions on Optimal Well Trajectories
No full text• In the planning of new wells, typically the same trajectory is used for conventional wells and wells with smart completions. This study demonstrates that the economically optimized trajectory for smart and conventional wells can be very different. Two new well trajectory optimization algorithms were developed using Stochastic Pattern Search (SPS) principles. In both algorithms random perturbations are made starting from an initial well trajectory, which are sent to a reservoir simulator whereafter the perturbation with the highest Net Present Value (NPV) is selected. New perturbations of the selected well trajectory are made and simulated to, again, select the highest NPV. This process is repeated until a certain stopping criteria is met. The two methods differ in the selection of the perturbations used to initiate the new iteration. In the SPS1 method every subsequent iteration starts from the perturbation with the highest NPV which may be the starting well from the previous iteration. In the SPS2 method the starting well from the previous iteration is excluded. This does not allow the SPS2 method to converge, but it avoids one of the main risks of the SPS1 method, i.e. that the optimization remains stuck in a local optimum. To demonstrate the difference between the optimal well trajectory of well with a conventional and smart completion, both the SPS1 and SPS2 method were evaluated using a realistic, but slightly simplified reservoir model. Both methods were able to optimize the trajectory for both conventional and smart completions. The SPS1 method quickly converged to a local optimum, whilst the SPS2 method was able to determine a trajectory with a significantly higher NPV for both the conventional and smart wells. Moreover, the optimal well trajectory with the smart completion, as found by the SPS2 algorithm, had a NPV that was 40% higher than the optimal trajectory for the conventional completion. It can therefore be concluded that when smart completions are assessed, well trajectory optimization can have very significant value impact and may be crucial in evaluating the full potential of the completion. Furthermore it was shown that, for the example considered, the SPS2 procedure is a good method for well trajectory optimization in a three-dimensional reservoir and although more testing is needed it is believed that is has potential to work with any type of completion.Civil Engineering and GeosciencesPetroleum Engineerin
Empowering smart city residents through legibility: A Digital Tool to Discover Smart City Projects
No full textThe role that smart technologies play and the data they generate is becoming central in cities; cities are adopting technologies as a new way of governance and making policies based on data. Increasingly, governments and companies implement data-driven strategies, and the number of sensors in the public space is increasing. This translates into abysmal amounts of data about people, their behavior and habits. While the use of smart technologies in cities and specifically in Amsterdam has many potential benefits—from improving local economy and transportation to quality of life and e-governance—there is a growing concern about the ethical risks. Martinez-Balleste et al. (2013) identify that their use in cities jeopardize citizens’ privacy. Moreover, one of the main problems of smart technologies in the public realm is that they are often placed without users’ consent and without providing any notice of their presence. At the same time, the attitude of smart city residents towards this new paradigm — along with the ethical, social and privacy implications that derive from it — is one of indifference. The misalignment between smart city residents attitudes and privacy behaviour is what motivates this project. This project aims to engage smart city residents with smart technologies in order to create awareness, better understanding of the privacy implications and build a democratic process for smart cities. The design solution focuses on empowering smart city users by making smart technologies, its privacy implications and data insights legible for users. By building this knowledge and making privacy implications more visible, users will be able to notice smart technologies in the public realm and spread awareness. Moreover, they will be better equipped to make inform decisions about smart city projects and co-shape the city they envision.Design for Interactio
Detection of Cognitive Features from Web Resources in Support of Cultural Modeling and Analysis
No full textThe World Wide Web serves as a valuable source of culture-relevant information, which can be used to support cultural modeling and analysis activities. Part of the challenge in exploiting the Web as a source of culture-relevant information relates to the need to detect and extract information about beliefs, attitudes, and values from a variety of different resources. The Web thus features a rich variety of information resources, and these are seldom categorized with respect to the dimensions in which cultural analysts are interested. Exploiting the Web as a source of culture-relevant information therefore requires techniques and approaches that enable cultural analysts to extract relevant information and organize extracted content in various ways. In this paper, we outline an approach to assist cultural analysts in the extraction and organization of relevant information. We show techniques that can be used to extract information about the attitudes, beliefs, and values of individuals, and how this data can, in turn, be used to support cultural modeling and analysis
Strategies for smart building realisation
No full textSmart buildings, as a concept, is now becoming prominent in the vocabulary of Architects,
Engineers, Construction contractors, Technology companies, Property developers and the
Estate or facility management function within organizations. Public or private sector, smart
building goals are now prevalent in corporate strategies whenever new build or retrofit /
refurbishment is planned.
But there seems no common consensus on what this really means. The 1990's and 2000's
witnessed much hype around intelligent buildings concepts. However, in many instances the
hype never produced tangible results. Now the scene has changed. Sustainability and carbon
management is increasingly on the agenda of boardroom decision making and smart in
smart buildings seems to have a purpose, almost as a mission statement.
The lack of clear definitions on what encompasses a smart building and what is to be
expected when utilising a smart building whether as a solitary or group experience is causing
the supply side industry to throttle back the adoption rate. Value structures justifying
adoption are not clear in this early adaptor stage. Thus costs associated with the realisation of
a smart building are quite hard to justify. This is compounded by the rapid pace of technology
advancement and the continual refresh of new products and solutions that purport to provide
an improved functionality or better price to performance advantage.
Thus strategies for smart building realisation need to be formalised into industry accepted
frameworks which can be applied in many market sectors - or verticals, and which can be
applied in the context of small, medium and large buildings or campus premises. This paper
presents some thought leadership in this emerging area of expertise and provides concepts
that may form the fundamentals for a future framework.
The author provides a perspective as a professional in Consulting for the Engineering and
Construction industry with regards to integrating ICT systems into the built environment. ICT
infrastructure comprises much of the building blocks for smart building enablement alongside
automation and controls, electronic security and facility management applications.
Converged IP networks, integrated command and control rooms, utility smart metering and
integrated BMS (iBMS) enables smart building functionalities to be implemented. This paper
presents viewpoints across all of these subject areas in the context of policies, technologies
and obstacles
Field evaluation of a deep learning-based smart variable-rate sprayer for targeted application of agrochemicals
No full textThe field performance of a newly developed novel smart variable-rate sprayer was evaluated. The sprayer uses convolutional neural networks (CNNs) for target detection and spot-applications of agrochemicals within potato (Solanum tuberosum L.) fields attacked by lamb's quarters (Chenopodium album L.) and corn spurry (Spergula arvensis L.) weeds and the early blight potato disease caused by Alternaria solani Sorauer. There was a non-significant effect of treatment conditions (i.e., cloudy, partly cloudy, and sunny) on spray volume during weed and diseased plant detection experiments (p-value = 0.93 and 0.75, respectively) showing that the smart sprayer performed well during all treatment conditions. There was a significant effect of spraying application techniques on the use of spray volume (p-value ≤ 0.05) reflecting a significant saving of spraying liquid during variable-rate application (VA). On average, the sprayer reduced spray volume by 47 and 51% for weeds and diseased plant detection experiments as compared to the values of chemicals applied at constant-rate application (CA), respectively, under all treatment conditions. The analysis of water-sensitive papers (WSP) data resulted in non-significant differences between CA and VA under all field conditions. These results suggest that this sprayer has a great potential to get a suitable spot application of agrochemicals and reduce the use of plant protection products thereby ensuring farm profits and environmental stewardship.Natural Science and Engineering Research Council of Canad
