IT i boendet : - en infrastruktur för vardagslivet

Jönsson-Brydsten, Monika January 2008 (has links)
The purpose of this thesis is to analyse the conditions of designing a technical solution (ICT) to assist everyday life in the home, in four objectives. First, to identify and analyse the everyday practice in terms of home-related values and activities. Second, to analyse a model for a technical and organizational developed ICT-solution in a local community. Third, to analyse the opportunities and dilemmas of ICT as a support system for everyday life, and fourth, to discuss how actors in society can interact with households in making daily life work The method of the thesis takes support in a so-called interactive research and aims to fulfill both the scientific quality criteria as well as requirements of relevancy for the practice. The thesis outlines a theoretical understanding of the individual construction of the home, based on everyday practice taking place in the home and neighbourhood, in an expanding residential landscape. The empirical parts of the thesis derive from two studies. The Husum study examines issues such as what a home is represented by, and what can be said to constitute a good home. The Vällingby study is analysing a model of a technical and organized ICT-solution in an experiment-house in a suburb to Stockholm. In this thesis ICT reinforces the home as a hub for everyday life. Households increase their flexibility and accessibility, support the relationship between people and strengthen the influence and a local foundation. ICT also creates new roles for actors in local society and evens out the landscape of everyday life.

Development of the B-mode measurements pipeline for QUBIC experiment / D´eveloppement du pipeline de mesure des modes B pour l’expérience QUBIC

Stolpovskiy, Mikhail 25 November 2016 (has links)
QUBIC est une expérience au sol en cours de construction dont le but est de mesurer les modes-B primordiaux du fond diffus cosmologique en utilisant la technique innovante de l’interférométrie bolométrique. Grace à la fusion entre interférométrie et imagerie,QUBIC a une très bonne sensibilité et un excellent contrôle des effets systématiques instrumentaux. De plus, du fait de la dépendance en fréquence du lobe synthétique,QUBIC peut être utilisé comme un spectre-imageur. Ces points pris en compte, la sensibilité globale de QUBIC au rapport tenseur/scalaire est 0.012. L’objectif de cette thèse est de d´écrire le code d’analyse de données de QUBIC, depuis la fabrication de cartes`a partir des données temporelle jusqu’`a la séparation de composantes astrophysique, l’estimation du spectre de puissance angulaire et celle des paramètres cosmologiques.Les aspects essentiels de ce travail sont les suivants: la fabrication de carte qui est très inhabituelle vis à vis des autres projets du domaine et le développement de la stratégie de couverture du ciel pour QUBIC. / QUBIC is a ground-based experiment aiming to measure the primordial B-modes, currently under construction, that uses the novel bolometric interferometry technique. Thanks to the fusion nature of QUBIC, it has very good sensitivity and excellent control of systematics. Moreover, the fact that the synthesized beam depends on the wavelength allows us to treat QUBIC as a spectro-polarimeter. These factors together give sensitivity on tensor-to-scalar ratio r 0.012. The goal of this thesis is to describe the pipeline of data analysis for QUBIC, from map-making of CMB from raw time-ordered data, through component separation and power spectra estimation to cosmological parameter estimation. The main accents of this work are: map-making, which is very unusual in comparison with other experiments in the field, and the development of scanning strategy for QUBIC.
