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

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
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

Smart Grid Test Bed Design and Implementation
No full textGiven there is currently a migration trend from traditional electrical supervisory control and data acquisition (SCADA) systems towards a smart grid based approach to critical infrastructure management. This project provides an evaluation of existing and proposed implementations for both traditional electrical SCADA and smart grid based architectures, and proposals a set of reference requirements which test bed implementations should implement. A high-level design for smart grid test beds is proposed and initial implementation performed, based on the proposed design, using open source and freely available software tools.\ud
\ud
The project examines the move towards smart grid based critical infrastructure management and illustrates the increased security requirements. The implemented test bed provides a basic framework for testing network requirements in a smart grid environment, as well as a platform for further research and development. Particularly to develop, implement and test network security related disturbances such as intrusion detection and network forensics.\ud
\ud
The project undertaken proposes and develops an architecture of the emulation of some smart grid functionality. The Common Open Research Emulator (CORE) platform was used to emulate the communication network of the smart grid. Specifically CORE was used to virtualise and emulate the TCP/IP networking stack. This is intended to be used for further evaluation and analysis, for example the analysis of application protocol messages, etc.\ud
\ud
As a proof of concept, software libraries were designed, developed and documented to enable and support the design and development of further smart grid emulated components, such as reclosers, switches, smart meters, etc. As part of the testing and evaluation a Modbus based smart meter emulator was developed to provide basic functionality of a smart meter. Further code was developed to send Modbus request messages to the emulated smart meter and receive Modbus responses from it. Although the functionality of the emulated components were limited, it does provide a starting point for further research and development. The design is extensible to enable the design and implementation of additional SCADA protocols.\ud
\ud
The project also defines an evaluation criteria for the evaluation of the implemented test bed, and experiments are designed to evaluate the test bed according to the defined criteria. The results of the experiments are collated and presented, and conclusions drawn from the results to facilitate discussion on the test bed implementation. The discussion undertaken also present possible future work
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
