Tekniker för detektion av neutriner med ultrahög energi

Ahmedi, Lawen, Ali, Mubarak, Castellanos, Larisa January 2017 (has links)
This project highlights various methods used to detect the elongated elemental particle neutrino. It is especially focused on the IceCube observatory, which uses Cherenkov light to detect these particles. Neutrino is an importnant building block in astrophysics and particle physics research as this particle can travel from great distances in time and space without interacting with matter. This means that high-energy neutrinos that are detected can orginate from strong explosions from outer space, even from explosions billion years ago, like Big Bang. This means that these particles carry a huge amount of information about the universe. The project also contains an experiment whose purpose is to demonstrate that with simple materials it is possible to detect particles that are not otherwise visible to the naked eye.

Dynamismes et structures de la perception dans l'œuvre de Charles Ferdinand Ramuz / Dynamisms and structures of perception in the work of Charles Ferdinand Ramuz

Keresztes-Kila, Noemi 29 November 2013 (has links)
Cette thèse a comme but de resituer l’œuvre de l’auteur suisse romand, Charles Ferdinand Ramuz dans le contexte français où elle a été souvent mal accueillie, plus particulièrement à l’époque contemporaine à sa création même. Afin de pouvoir situer les questionnements et les hypothèses, elle dresse un panorama des différents aspects de la réception de l’œuvre en question (malentendus, interprétations linguistiques, esthétiques et narratologiques). Ce travail souhaite s’inscrire dans le renouveau critique qui s’est fait jour dans les années soixante. Il étudie les stratégies d’expression et les techniques narratives qui rendraient possible une « langue-image » et une esthétique de la perception phénoménologico-cinématographique. Il consacre une attention particulière à l’usage ramuzien du pronom on ainsi qu’à la mise en œuvre des effets cinématographiques. L’analyse détaillée de ces constantes de l’écriture ramuzienne permettent non seulement de redéfinir les enjeux d’un regard détaché, objectif et de redécouvir le foyer perceptif comme doté de conscience et de cognition, mais aussi de poser une question qui peut paraître bouleversante : l’écriture de cet écrivain vaudois, mettrait-elle en œuvre ce que la création romanesque associée à la mouvance du Nouveau Roman définit et théorise trente ans plus tard ? / The aim of the present thesis is to resituate the work of the Swiss writer Charles Ferdinand Ramuz in the French context in which it was frequently badly received, namely in the contemporary age of its creation. In order to situate the questions and hypotheses, the thesis will provide a panorama of the different aspects of the work’s reception in question (misunderstandings, linguistic, aesthetic and narratological interpretations). This study aims to follow in the lines of the Critical Renewal which appeared in the sixties. It will study the strategies of expression and the narrative techniques that would allow a «language-image» and an aesthetics of the phenomenological-cinematographic perception. It will focus especially on Ramuz’ usage of “on” (we) as well as on the realization of the cinematographic effects. The detailed analysis of these constants in Ramuz’ writing make it possible not only to redefine the challenges of a detached and objective view and to rediscover the perceptive focus as if it was provided with conscience and cognition but also to raise a seemingly upsetting question: may it be possible that the writing of this Vaud writer already accomplishes what the Romanesque creation in association with the movement of the New Novel (Nouveau Roman) defines and theorises thirty years later ?
