Characterization of Heterogeneous Fractured Reservoirs Using Solute Tracer Tests: Application to the Underground Laboratory of Grimsel
(2018)As part of the Swiss Energy Strategy 2050, Switzerland has decided to make a transition from nuclear power plants to renewable energies and invest in the development of these alternatives. As a response to this energy strategy, a decametre-scale in-situ stimulation and circulation (ISC) experiment was set up to better investigate the challenges associated to deep geothermal reservoir creations and fill the gap between full scale and ...Master Thesis -
Densifying Sparse VIO: a Mesh-based approach using Structural Regularities.
(2018)The ideal vision system for an autonomous robot would not only provide the robot’s position and orientation (localization), but also an accurate and complete model of the scene (mapping). While localization information allows for controlling the robot, a map of the scene allows for collision-free navigation; combined, a robot can achieve full autonomy. Visual Inertial Odometry (VIO) algorithms have shown impressive localization results ...Master Thesis -
A scenario-based approach to crowd safety of major events and its interface to public transport
(2018)In Switzerland, more than five million visitors annually trust in event operators, authorities and public transport operators to keep them safe on their way home from events. Some of these events push the public transport system to or past its limits. The resulting mismatch between demand and capacity can lead to the accumulation of crowds and thus creates a risk for crowd-related accidents. In the case of disturbances of the public ...Master Thesis -
A Cognitive Model for Routing in Agent-based Modelling
(2018)Routing is an essential process for pedestrian Agent-Based Modelling (ABM). ABM is a computational tool to model and analyse human behaviour. The process of routing is well-studied in both Computer Science and Cognitive Science. However, routing in ABM is often taken for granted and both its impact and its implementation are disregarded. In this work, I unpack the blackbox of routing in ABM and take insights from Cognitive Science ...Master Thesis -
Application and Comparison of Financial Risk Measures in Earthquake Engineering
(2017)The devastating effects of earthquakes in terms of casualties and monetary losses on individuals, companies and on the whole society highlight the need for effective and informative seismic risk measurement and management. Risk measures enable to measure risk related to an associated hazard and facilitate decision making defining the risk appetite of the decision maker. These measures have been investigated extensively in quantitative ...Master Thesis -
Non-Spatial and Spatial Statistics for Analysing Human Perception of the Built Environment
(2018)The world is rapidly urbanising, which makes the liveability of cities an important issue in our times. New sources of data on urban citizens including social media, video footage, and even fitness data, are also becoming increasingly available. This study is motivated by these two trends. We analyse data gathered in a Virtual Reality experiment to find correlations between features of the urban environment and people’s perceptions of ...Master Thesis -
The Influence of the Resolution of Topography and Surface Fields on the Simulation of Orographic Moist Convection
(2018)Moist convection has a strong impact on the Earth’s water and energy budgets. It redistributes moisture and heat vertically and thus changes the stratification ofthe atmosphere. The associated clouds interact with radiation and generate precipitation. Convective precipitation can be very intense and may cause flooding and trigger land slides. A good understanding and simulation of moist convection is therefore of crucial importance for ...Master Thesis -
Distributed Join Result Materialization over High-Performance Networks
(2017)Distributed Joins over a network have been researched for decades, usually focusing on adapting the join to the network connecting the nodes holding the relations. Most research has gone into optimizing the join itself, i.e. the identification of matching tuples, however the effective materialization of the join result is equally important. The main performance issue identified by materialization strategies is that the network performs ...Master Thesis -

Travelling waves in somitogenesis: collective cellular properties emerge from time-delayed juxtacrine oscillation coupling
(2017)The sculpturing of the vertebrate body plan into segments begins with the sequential formation of somites in the presomitic mesoderm (PSM). The rhythmicity of this process is controlled by travelling waves of gene expression which sweep across the PSM. These kinetic waves emerge from coupled cellular oscillators and travel in the direction of an increasing gradient of oscillation period. The oscillations are driven by autorepression of ...Master Thesis
