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

A smart tool for the diagnosis of Parkinsonian syndrome using wireless watches
No full textThis work is licensed under a Creative Commons Attribution 3.0 License.Early detection and diagnosis of Parkinson disease will provide a good chance for patients to take early actions and prevent its further development. In this paper, a smart tool for the diagnosis of Parkinsonian syndromes is designed and developed using low-cost Texas Instruments eZ430-Chronos wireless watches. With this smart tool, Parkinson Bradykinesia is detected based on the cycle of a human gait, with the watch worn on the foot, and Parkinson Tremor shaking is detected and differed by frequency 0 to 8 Hz on the arm in real-time with a developed statistical diagnosis chart. It can be used in small clinics as well as home environment due to its low-cost and easy-use property
Why aren't we all living in Smart Homes
No full textVisions of the Future, like the Jetsons cartoons, show homes which are smart and able to control household appliances, to make living easier and more comfortable. Although much research has been carried out into the effectiveness of different visualisation techniques for conveying useful energy consumption information to householders, and in techniques for controlling the timing and coordination of appliance use, these techniques have failed to achieve widespread penetration, and the vision still seems far from a reality. This paper examines the reasons why smart home technologies have so far failed to have any real impact, which is intricately intertwined with the design of visualisations in this context, and why we are not already living in Smart Homes. It examines these questions under four sections: Technology, Consumers, Electricity retailers and Government agencies, using examples from New Zealand’s electricity sector
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
Response to Commentary "efficacy of inspiratory muscle training in chronic heart failure patients"
No full textIn their letter Plentz and colleagues attempt to highlight discrepancies between their review work and that of Smart et al. Plentz and colleagues suggest that the search by Smart et al. was too narrow. We challenge Plentz and colleagues to find omitted studies that were published in the stipulated time frame as, in addition to the stipulated search, extensive hand searching was conducted. The discrepancy between the previous works and the work of Smart et al. may be explained by the fact that we only recorded papers where we were required to read more than the title (e.g. abstracts or full manuscripts) in order to come to a decision to exclude a study. Second, Plentz and colleagues suggest our review included too many studies, which perhaps contradicts their comment above? We do however acknowledge that journal word limits permitting the inclusion of a sensitivity analysis (e.g. removal of studies of Winkelmann and Laoutaris) may have been helpful in teasing out any effects of heterogenic studies
Intelligent Energy Optimization for User Intelligible Goals in Smart Home Environments
No full textIntelligent management of energy consumption is one of the key issues for future energy distribution systems, smart buildings, and consumer appliances. The problem can be tackled both from the point of view of the utility provider, with the intelligence embedded in the smart grid, or from the point of view of the consumer, thanks to suitable local energy management systems (EMS). Conserving energy, however, should respect the user requirements regarding the desired state of the environment, therefore an EMS should constantly and intelligently find the balance between user requirements and energy saving. The paper proposes a solution to this problem, based on explicit high-level modeling of user intentions and automatic control of device states through the solution and optimization of a constrained Boolean satisfiability problem. The proposed approach has been integrated into a smart environment framework, and promising preliminary results are reporte
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
