As the fifth most visited website on the internet today, the user-generated encyclopaedia Wikipedia has attracted significant attention from researchers based across the academic disciplines. However, this previous work has generally neglected the multilingual aspects of the encyclopaedia, and downplayed the significance of translation within the collaborative processes of content creation that take place within the platform. Consequently, this doctoral thesis has set out to investigate the people and practices involved in the co-production and dissemination of knowledge across linguistic and cultural borders in the context of Wikipedia. By developing an analytical approach that combines narrative theory (Baker 2006) with insights drawn from the work of Henri Lefebvre (1974/1991) and Michel Foucault (1967/1986), I have examined the construction of 27 city-related articles published within the English- and French-language editions of the platform. This analysis has shown that Wikipedia volunteers make abundant use of source materials published in a diversity of languages other than that in which they are writing, and that the creation of these encyclopaedic articles involves a wide range of partly overlapping multilingual activities, a complex combination of translating, re-contextualising, summarising and synthesising. My study has also brought to light the multi-faceted negotiations that occur between the different participants involved in these processes of intersubjective knowledge production. This has drawn attention to Wikipedia as a space of discordant juxtaposition and creative simultaneity, and foregrounded the cacophony of opposing narrative positionings present within each article-focused community of multilingual produsers.

abstract: Smart cities are the next wave of rapid expansion of Internet of Things (IoT). A smart city is a designation given to a city that incorporates information and communication technologies (ICT) to enhance the quality and performance of urban services, such as energy, transportation, healthcare, communications, entertainments, education, e-commerce, businesses, city management, and utilities, to reduce resource consumption, wastage and overall costs. The overarching aim of a smart city is to enhance the quality of living for its residents and businesses, through technology. In a large ecosystem, like a smart city, many organizations and companies collaborate with the smart city government to improve the smart city. These entities may need to store and share critical data with each other. A smart city has several thousands of smart devices and sensors deployed across the city. Storing critical data in a secure and scalable manner is an important issue in a smart city. While current cloud-based services, like Splunk and ELK (Elasticsearch-Logstash-Kibana), offer a centralized view and control over the IT operations of these smart devices, it is still prone to insider attacks, data tampering, and rogue administrator problems. In this thesis, we present an approach using blockchain to recovering critical data from unauthorized modifications. We use extensive simulations based on complex adaptive system theory, for evaluation of our approach. Through mathematical proof we proved that the approach always detects an unauthorized modification of critical data. / Dissertation/Thesis / Masters Thesis Computer Science 2017
