Genetic control of photoreceptor terminal differentiation in "Drosophila melanogaster"

Bernardo Garcia, Javier ; Sprecher, Simon (Dir.)

Thèse de doctorat : Université de Fribourg, 2018 ; no. 2066.

Warum bilden sich Fotorezeptoren gerade im Auge aus? Obwohl diese Frage einfach erscheint, ist sie aus biologischer Sicht doch sehr bedeutend und bedarf eventuell einer komplexen Antwort. Allgemein lässt sich sagen, dass Tiere eine Vielfalt von hoch spezialisierten Sinnesorganen entwickelt haben, durch die sie Informationen aus ihrer Umwelt aufnehmen und auf diese Weise ihr Überleben sichern....

The functions of RMR proteins in the "Physcomitrella patens" secretory pathway

Fahr, Noémie ; Neuhaus, Jean-Marc (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Plant vacuoles play a wide range of functions within the cell, from the maintenance of turgor pressure and rigidity, to the storage or degradation of various molecules. Two types of vacuoles with distinct pH can coexist in the same single cell. Acidic vacuoles can be considered as homologues to animal lysosomes while neutral vacuoles are involved in proteins and secondary metabolites storage....

Assessing soil micro-eukaryotic diversity using high-throughput amplicons sequencing : spatial patterns from local to global scales and response to ecosystem perturbation

Seppey, Christophe Victor William ; Mitchell, Edward AD (Dir.) ; Lara, Enrique (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Micro-eukaryotes exhibit a huge diversity which fulfils many essential functions in the colonized ecosystems. These micro-organisms are involved in every level of microbial trophic networks. They interact with each other and with other biota like prokaryotes or macro-organisms, and influence element cycles like the carbon or nitrogen cycle. The diversity and ecology of micro-eukaryotes are...

Liquid stream processing on the web : a JavaScript framework

Babazadeh, Masiar ; Pautasso, Cesare (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017INFO015.

The Web is rapidly becoming a mature platform to host distributed applications. Pervasive computing application running on the Web are now common in the era of the Web of Things, which has made it increasingly simple to integrate sensors and microcontrollers in our everyday life. Such devices are of great in- terest to Makers with basic Web development skills. With them, Makers are able to...

Hydraulics and sedimentary processes in the karst aquifer of Milandre (Jura Mountains, Switzerland)

Vuilleumier, Cécile ; Jeannin, Pierre-Yves (Dir.) ; Perrochet, Pierre (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

This thesis aims at characterizing the sedimentary processes taking place in the karst aquifer of Milandre (Switzerland) both by direct observation inside the conduit network and through numerical modeling. A physics based pipe flow model of the downstream part of the karst system is developed on the basis of measurements of hydraulic heads, flow rates and flow velocities performed in the...

Understanding the impact of risk perception in leisure tourism-related decisions and the role of attitudes and preferences

Sarman, Igor ; Maggi, Rico (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2016 ; 2016ECO010.

The contemporary tourism industry is often forced to face events that represent a threat to individuals’ safety. Life- threatening events pose a challenge to travelers’ intentions to plan a leisure trip and influence in a substantive manner human decisions. Individual sensitivity towards potential hazards show a great deal of variation among consumers and several tourism scholars have spent...

La nouvelle ville traditionnelle : géographies d'un modèle urbain mobile

Dupuis, Blaise ; Söderström, Ola (Dir.) ; Chabard, Pierre (Codir.) ; Ghorra-Gobin, Cynthia (Codir.) ; Lévy, Jacques (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Cette thèse de doctorat en géographie humaine analyse comment les modèles urbains façonnent, et sont façonnés par, la circulation accrue des connaissances architecturales et urbanistiques. L’objectif est de mieux comprendre, à travers l’étude des pratiques et des projets des architectes, les modalités de traduction d’un modèle – en l’occurrence le modèle néo-traditionnel -...

Text clustering with styles

Kocher, MIrco ; Savoy, Jacques (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

This thesis mainly describes the author clustering problem where, based on a set of n texts, the goal is to determine the number k of distinct authors and regroup the texts into k classes according to their author. We iteratively build a stable and simple model for text clustering with styles. We start by designing a measure reflecting the (un)certainty of the proposed...
