Designing Resilient Distributed embedded Systems is a challenging task. One of the design issues is to guarantee correct behavior of the system during the runtime. It demands verification that information propagated through the system is reliable. The goal of this thesis is a research and implementation of an analysis that should identify obsolescence of variables due to delays caused by scheduling and communication in real-time systems. Analysis will be designed for Ensemble-Based Component System (EBCS) semantics because it enables precise specification and analysis of important properties. The main problem is to find a suitable input model of the analysis and find its possible limits. Effort should be put in balancing between the level of abstraction given to a RDS developer and power of the analysis itself. The main benefit of the analysis will be detection of situations in which data processed in RDS are outdated and can cause incorrect behavior of particular components.

La situation des langues régionales pose aujourd’hui de nombreuses questions, et particulièrement dans des zones linguistiques charnières et transitoires, telles que le département de la Drôme. À l’épreuve du contact de deux domaines linguistiques gallo-romans, l’occitan et le francoprovençal mais également à celui du français, la Drôme est un territoire riche de sa pluralité, tant linguistique que culturelle. Pourtant, à l’heure où la transmission familiale et les pratiques de l’occitan deviennent sporadiques et isolées, il était nécessaire d’établir un état des lieux général de la langue au sein des institutions, scolaires notamment, mais également au sein de la communauté linguistique. Identifier les divers profils de locuteurs, estimer la vitalité des pratiques, évaluer le changement linguistique et faire émerger les représentations linguistiques ont ainsi permis d’exposer une image globale du département. À l’image du territoire, le visage linguistique de la Drôme est tout aussi complexe et pluriel : entre conflits d’identités, de langues et volontés de sauvegarde par l’enseignement. / Nowadays the situation of regional languages raises many questions and more particularly in border and transiting linguistic areas such as the Drôme area. Being in contact with two Gallo-Roman linguistic estates, the Occitan and the Franco-Provencal but also with the French language, Drôme territory is rich from its plurality, both linguistic and cultural. Though at a time when family transmission and use of Occitan has become sporadic and isolated, it is necessary to draw out an overall state of the art of the language within institutions, especially at schools, but also within the linguistic community. Identifying the speakers’ various profiles, measuring the liveliness of the language use, evaluating linguistic shifts and bringing out the linguistic representations did set out a holistic picture of the area. The linguistic representation of the Drôme area is just the same as the territory itself, as complex and manifold: with both an identity and language encounter and the desire to save it through teaching.

This thesis takes a deeper look into customer behaviours when it comes to buying new mobile phones. We take a look at four main types of planned obsolescence we’ve found, which include: economic obsolescence, obsolescence of function, obsolescence of desirability and obsolescence of quality. With a questionnaire and focus group study we try to find out the underlying reasons why users buy new phones while their old ones are still functional. Since this is not a new subject, we try to map the problems we encounter in our study to the four already defined forms described above, and we try to see if there are other forms that are not yet defined. What we found out was that these four categories hold up very well, but are not as separate as one would have thought when reading. While we find out many reasons why people change their phones we do not offer a solution. But we do offer a better understanding of the problem and hope the consumer will take part of the knowledge.

Esse estudo aborda conceitos e obras que inter-relacionam teoria e prática no processo de criação do projeto “algum pequeno oásis de fatalidade, perdido num deserto de erros”, ligada à minha pesquisa de mestrado em Poéticas Visuais, na qual exploro arquivos digitais pessoais e suas implicações nas esferas públicas e privadas através da apropriação de discos rígidos descartados como sucata. O método para criação dessa série de trabalhos foi a de busca, recuperação, compilação e criação de experimentos; busca de HDs descartados como lixo eletrônico, recuperação e compilação de imagens em coleções (catálogos visuais) e criação de experimentos audiovisuais como instalações, websites e livros de artista. As experiências realizadas evocam questões e reflexões sobre pautas do cotidiano contemporâneo como o arquivamento; a privacidade e a vigilância das imagens no ambiente digital/virtual; o excesso de produção visual a partir de dispositivos móveis, entre outros. Essa reflexão foi geradora de 3 encontros-oficinas de reflexão e produção dos quais resultaram a criação de 10 trabalhos colaborativos. Desse grupo de experimentos, 3 trabalhos foram selecionados por mim para serem criados em processo de coautoria. / This study approaches concepts and works that interrelate theory and practice in the process of creating the project “some little oasis of fatality amid a wilderness of error”, linked to my master degree research in Visual Poetry, in which I explore personal digital files and their implications in the public and private spheres through the appropriation of discards Hard Disks as e-waste. The method for creating this series of works was the search, recovery, compilation and creation of experiments; search for discards discarded as electronic waste, recovery and compilation of images in collections (visual catalogs) and creation of audiovisual experiments as installations, websites and artist books. The experiments carried out evoke questions and reflections on contemporary everyday routines such as archiving; privacy and image surveillance in the digital / virtual environment; the excess of visual production from mobile devices, among others. This reflection generated 3 meetings-workshops of reflection and production, which resulted in the creation of 10 collaborative works. From this group of experiments, 3 works were selected by me to be created in the process of co-authorship.

Urban highway infrastructure in North America has been singularly designed for the automobile, severing parts of the urban fabric, blighting our once-thriving city centres and resulting in spaces that are void of the human scale. The Cogswell Interchange in Halifax, Nova Scotia, Canada is such an infrastructure, cutting through the downtown core and heritage district. This thesis investigates the Cogswell Interchange in an attempt to animate and enliven a dead urban space, reducing traffic and bringing new activity and life to the street. Reappropriating parts of vehicular infrastructure for cyclist and pedestrian use and creating a variety of activities and programs (gallery, gym, restaurant, park) enables an increased connectivity for pedestrians and cyclists and brings a more human-scale urbanity to the site. The infrastructure itself becomes a framework upon which to build, revisioned as an active, vibrant place which people can experience with a renewed sense of wonder and appreciation.

[pt] Vivemos em uma época marcada por grandes transformações tecnológicas e conseqüentemente por muitas mudanças subjetivas. Nos dias de hoje, é possível perceber o significativo aumento de usuários de celulares na nossa sociedade. O mercado multiplica-se rapidamente revelando um cenário em franca expansão. Este estudo objetiva, principalmente, investigar como os jovens da classe média do Rio de Janeiro lidam com questões como a obsolescência, o consumo e as freqüentes inovações tecnológicas no campo dos aparelhos celulares. Para alcançar esse objetivo, foi realizada uma pesquisa qualitativa com 15 jovens de ambos os sexos. Esses jovens tinham, em média, 26 anos de idade. Quase todos eram profissionais com nível superior e usuários assíduos de celulares há mais de 5 anos. As entrevistas foram realizadas on line, através do programa de conversação MSN Messenger. A análise dos depoimentos dos participantes revelou o papel central que os celulares vêm assumindo. A maioria dos entrevistados admite ter o celular por perto e ligado o tempo todo. No que se refere ao consumo de celulares, contudo, os depoimentos foram contraditórios. A maioria dos entrevistados fica com o mesmo celular um curto período de tempo, alegando os mais diferentes motivos para trocar de aparelho. Afirmam que se deve mudar de celular somente quando este pára de funcionar. Mesmo assim, trocam de aparelho muito antes do tempo previsto. As razões para esse comportamento estão, principalmente, no fato de eles se sentirem fortemente atraídos pelas freqüentes inovações tecnológicas dos aparelhos. / [en] We live in a time of ever-increasing technological changes. Nowadays, we can clearly see a significant growth in the number of cell phone users, which shows how fast the this market is expanding. The purpose of the present study was to find out how middle class young people deal with the obsolescence, consumption and constant innovations in cell phones. To reach this goal, a qualitative study was carried out with 15 young people, both male and female, whose average age was 26. Most of them were professionals and had a university degree. All had been intensively using cell phones for more than 5 years. The interviews were carried out on-line through the MSN Messenger chat program. The results showed that cell phones play a central role in their lives. Most of the interviewees admitted that they always carry their cell phones and never switch them off. However, in what concerns their consumption, the participants` statements were contradictory. Most of the interviewees keep the same model of cell phone for a short period of time, providing a host of different reasons for changing it. They all say that a new model should be bought only in case of malfunction of the previous one. However, all of them admit changing phones long before this happens. And the reasons for this behavior lie in the fact that they are attracted by the constant technological innovations.

This thesis project addresses the obsolescence of technology through the lens of accessibility to public services. It explores the processes by which electronic devices age in regards to a technological normativity that marginalizes owners of obsolete devices. My research focuses on two main questions: How might we enable owners of non-smart phones to have access to public services that have been digitalized? How might we design public services’ infrastructure in a way that challenges the obsoletion processes of technological devices?  The research is based upon a critical analysis of the term ‘obsolescence’, low-tech approaches and studies that examine the accessibility of technology. This work is based on the study of the digitalization of public services in Sweden, with specific attention to public transportation and to the electronic identification technology which enables access to various essential public services. I present the exploration of these services through the lens of obsolescence and encounter with users of obsolete devices. This leads to the design of two prototypes that propose ways of integrating obsolete devices’ users in the existing digitalized Swedish infrastructures, followed by their analysis. The designs seek to take a critical stand on technological progress as it is understood in the technology industry and propose ways of reimagining the digitalization of public services while taking into account the obsoletion processes they foster. Overall, I argue for design for obsolete devices as a way of caring for groups that are put aside during technological innovation processes. I propose ways of ‘circuit bending’ public services’ infrastructures in a way that is more hospitable to obsolete devices.
