Deep learning for 3D hand biometric systems

Svoboda, Jan ; Bronstein, Michael (Dir.) ; Masci, Jonathan (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO007.

Hands are an indispensable part of human bodies used in our everyday life to express ourselves and manipulate the surrounding world. Moreover, a hand contains highly- unique characteristics that allow for distinguishing among different individuals. Though fingerprints are widely-known for this, the hand also has a unique geometric shape, palmprint, and vein structure. The shapes of a hand and...

Exposing concurrency failures : a comprehensive survey of the state of the art and a novel approach to reproduce field failures

Bianchi, Francesco Adalberto ; Pezzè, Mauro (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO015.

With the rapid advance of multi-core and distributed architectures, concurrent systems are becoming more and more popular. Concurrent systems are extremely hard to develop and validate, as their overall behavior depends on the non-deterministic interleaving of the execution flows that comprise the system. Wrong and unexpected interleavings may lead to concurrency faults that are extremely...

Engineering metal oxides for UV-stable perovskite solar cells

Roose, Bart ; Steiner, Ullrich (Dir.)

Thèse de doctorat : Université de Fribourg, 2017 ; no. 2015.

This thesis is a study of the role of the metal oxide electron transporting material in perovskite solar cells. The central research question is how the metal oxide influences the stability of perovskite solar cells and how the metal oxide can be modified to improve the stability. The thesis begins by providing four background chapters. Chapter 1 explains the need for solar energy and what...

Cultural similarities and differences in couples' adjustment to competing family and work demands

Wang, Zhiyun ; Perrez, Meinrad (Dir.)

Thèse de doctorat : Université de Fribourg, 2010.

Conflicting work and family demands can lead to individual and interpersonal stress in close relationships. The literature suggests that individuals from various cultural contexts differ in how they organize domestic work in the family and in the support they receive from other persons. At the same time, past findings suggest effects of culture on individuals’ emotional behaviors and...

Division of the single mitochondrion in "Trypanosoma brucei" and its impact on the cell cycle

Chanez, Anne-Laure ; Schneider, André (Dir.)

Thèse de doctorat : Université de Fribourg, 2006 ; no 1541.

Trypanosoma brucei is one of the earliest diverging eukaryotes with a bona fide mitochondrion. In contrast to most other eukaryotes, it has a single mitochondrion only which shows a large network-like morphology. This unique feature makes T. brucei an excellent model to study some unique aspects of mitochondrial biology. In the first part of this thesis, we used T. brucei as a model to study the...

The chemosensory system of "drosophila" larvae : neuroanatomy and behaviour

Colomb, Julien ; Stocker, Reinhard F. (Dir.)

Thèse de doctorat : Université de Fribourg, 2006.

This PhD thesis investigates the larval chemosensory system of Drosophila melanogaster, focusing on four different issues. The main work was directed on organisational aspects of the larval taste system and tried to show that the Drosophila larva could serve as a gustatory model system of general importance. Analysing both the gustatory projection patterns in the brain (1) and their potential...

The larval chemosensory system of Drosophila melanogaster : neuroanatomy and neurotransmitter distribution

Python, François ; Stocker, Reinhard (Dir.)

Thèse de doctorat : Université de Fribourg, 2002 ; no 1372.

The goal of my Ph.D. thesis was to study the larval chemosensory system of the fruit fly Drosophila melanogaster, both in terms of its organization and neurotransmitter content. My studies were based on the enhancer trap technique, which provides useful neuronal marker lines and allows ectopic expression of any transgene of interest in the labeled cells. Four enhancer trap lines selected for...

  • It carries about 23 gustatory afferents from the distal TO sensilla and the remaining dorsolateral sensilla, as well as seven gustatory afferents from the VO (Table 1) (Chu-Wang and Axtell, 1972a; Chu-Wang and Axtell, 1972b; Campos-Ortega and Hartenstein, 1997)....

Interactions between members of the Bcl-2 family, other protein partners and new survival factors

Conus, Sébastien ; Borner, Christoph (Dir.) ; Simon, Hans-Uwe (Codir.)

Thèse de doctorat : Université de Fribourg, 2001 ; No 1351.

Genetic and biochemical studies in C. elegans have shown that developmental programmed cell death requires a CED-4 mediated activation of the caspase CED-3. CED-9 acts as a death protector by directly interacting with and inhibiting the function of CED-4. CED-9 can be prevented from acting by binding to the death factor Egl-1. This apoptotic machinery seems to be conserved between worms and...

Understanding apoptosis involved in the development and treatment of malignancies

Genini, Davide ; Rusconi, Sandro (Dir.) ; Martinou, Jean-Claude (Codir.) ; Leoni, Lorenzo (Codir.)

Thèse de doctorat : Université de Fribourg, 2000 ; nr. 1321.

Apoptosis is a key event occurring in living organisms. In order to maintain tissue homeostasis, a comparable number of cells have to die to compensate for the cells produced by mitosis. However in many diseases this mechanism is altered. Once a malignancy is established, the conventional approach is to treat cells with drugs able to induce apoptosis. Although the execution of apoptosis is a...
