Living the prison : An ethnographic study of indefinite incarceration in Switzerland

Marti, Irene ; Hertz, Ellen (Dir.) ; Hostettler, Ueli (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2020 ; TH 2820.

During the first half of the 20th century, rehabilitation served as the main paradigm for criminal policy in Switzerland, as in most so-called Western countries. However, changing demands for security and public pressure over the past decades have led to a shift towards a more punitive and hard-line approach to crime. This ‘punitive turn’ in criminal policy has produced more investment...

Distributed systems and trusted execution environments : trade-offs and challenges

Pereira Pires, Rafael ; Felber, Pascal (Dir.) ; Pasin, Marcelo (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Security and privacy concerns in computer systems have grown in importance with the ubiquity of connected devices. Additionally, cloud computing boosts such distress as private data is stored and processed in multi-tenant infrastructure providers. In recent years, trusted execution environments (TEEs) have caught the attention of scientific and industry communities as they became largely...

Towards compact ultralow phase noise lasers and microwave signals based on new approaches

Brochard, Pierre ; Südmeyer, Thomas (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Today, the lowest phase noise microwave signals are generated optically by frequency division of an ultra-stable optical reference using a femtosecond frequency comb. In the commonly used approach, the ultra-stable optical reference is obtained by frequency-stabilizing a laser to a high-finesse ultra-low expansion optical cavity, and the frequency division is performed by optically locking a...

The foraging ecology of two neighbouring chimpanzee communities from Budongo Forest

Villioth, Jakob ; Newton-Fisher, Nicholas E. (Dir.) ; Zuberbühler, Klaus (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Chimpanzees (Pan troglodytes) often serve as a model species to test socio-ecological theories of foraging behaviour. Due to a high degree of fission-fusion dynamics, essential foraging variables, such as group size, patch size and travel distance, are expected to be more closely linked in chimpanzees than in animals that forage in cohesive groups. While it has been clearly established...

Modeling heat and fluid flow in discrete fracture networks : application to fluid-driven seismicity and engineered geothermal systems

Jansen, Gunnar ; Miller, Stephen A. (Dir.) ; Valley, Benoît (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Understanding the dynamics of naturally fractured systems and fractured reservoirs in terms of flow, heat transport and fracture stability (e.g. earthquakes) is important for a range of applications including geothermal systems, waste water injection and natural fluid-driven seismicity. Many numerical codes exist that can simulate aspects of these dynamics, but in general require either expensive...

Ontology engineering using formal concept analysis from unstructured textual data

Jabbari, Simin ; Stoffel, Kilian (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2019 ; 2806.

Knowledge extraction especially from unstructured data such as texts has been always considered as one of the highly demanded requests with lots of applications in almost all industries. Design and building of solutions that are capable of extracting knowledge, in an almost automated way, is not an easy task at all. Many researchers have proposed variety of methodologies and algorithms to...

Conditioning groundwater flow parameters with iterative ensemble smoothers : analysis and approaches in the continuous and the discrete cases

Lam, Dan-Thuy ; Renard, Philippe (Dir.) ; Kerrou, Jaouher (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Data assimilation (DA) consists in combining observations and predictions of a numerical model to produce an optimal estimate of the evolving state of a system. Over the last decade, DA methods based on the Ensemble Kalman Filter (EnKF) have been particularly explored in various geoscience fields for inverse modelling. Although this type of ensemble methods can handle high-dimensional systems,...

The role of insecticides and malaria infection on the mosquito’s behaviour and the consequences for malaria transmission

Thiévent, Kevin ; Koella, Jacob (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Insecticide treated bed nets (ITNs) are one of the most cost-effective techniques used for malaria control. While the repellent and irritant actions of ITNs offer personal protection, their insecticidal action contributes to community protection by lowering the number of infectious mosquitoes in the population. Despite this, the efficacy of ITNs to provide both personal and community protection...

Wirkungsweise und Effekte sozialer Unterstützung in Ausbildung und Schule

Hofmann, Claudia ; Tschan, Franziska (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

The transition from school to work is one of the major developmental tasks for young adults and has important consequences for further career development. It is also a particular challenge for young people with learning difficulties. Social support is considered to be an important facilitating factor in early career development and is therefore particularly important for these young people. In...

Impacts of urban gardening on soil quality, soil fauna and soil multifunctionality

Tresch, Simon ; Le Bayon, Claire (Dir.) ; Fliessbach, Andreas (Codir.) ; Moretti, Marco (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Urban gardens are important and at the same time popular greenspaces. As urban areas are expanding globally, urban gardens play an increasingly important role in contributing to essential ecosystem services, well-being of citizens, and biodiversity in a city. Gardening activities determine above- and belowground diversity of plants and insects. However, the effect of gardening activities on soil...
