Detection of Hazardous Ground Movements with Instantaneous Velocity Estimates by GNSS
(2019)The motivation for this work is to rapidly assess whether a GNSS (Global Navigation Satellite System) station is moving hazardously or not. The GNSS stations of interest are located on moving land masses – like rock glaciers – in alpine regions in Switzerland. The purpose is to support real-time natural hazard early warning systems with information on ground movements. One of the main problems with geodetic high-precision GNSS positioning ...Doctoral Thesis -
Ecohydrological sensitivity to climatic variables: dissecting the water tower of Europe
(2019)The water balance in mountain regions describes the relations between precipitation, snow accumulation and melt, evapotranspiration and soil moisture and determines the availability of water for runoff in downstream areas. Climate change is affecting the water budget of mountains at a fast pace and it has thus become a priority for hydrologists to quantify the vulnerability of each hydrological component to climate change, in order to ...Doctoral Thesis -
Optimal energy system and retrofit measures for residential buildings/districts
(2018)Scientific evidence for climate change and the exacerbating role of anthropogenic greenhouse gas (GHG) emissions is indisputable. A large part of the GHG emissions can be attributed to urban built infrastructure including residential buildings, and therefore, must go through a process of decarbonization. Specific policy measures are carefully drafted in order to accelerate the decarbonization process, especially in the EU and ...Doctoral Thesis -
A Lagrangian Analysis of the Dynamical and Thermodynamic Drivers of Greenland Warm Events during 1979-2017
(2019)The acceleration of mass loss from the Greenland Ice Sheet (GrIS) since the late 1990s was primarily driven by increased surface melt, partly concentrated in single extreme melt events. A textbook example was observed around 12 July 2012 (EV69), when almost the entire GrIS was melting, including Summit Station at 3216 m in the dry inland plateau. The melt event coincided with strong meridional air mass transport towards the GrIS followed ...Master Thesis -
Repurposing gamma-hydroxybutyrate for neuropsychiatric disorders? Examining its effects on sleep neurophysiology, neuro- immune interaction and brain metabolites in healthy men
(2019)Neuropsychiatric disorders represent a major health care challenge of the 21st century. Despite the high prevalence of these disorders, most of the currently available psychopharmacological therapies show suboptimal efficacy. Thus, there is an urgent need for novel, effective and sustainable psychiatric treatments. Unfortunately, major pharmaceutical companies have abandoned neuropsychiatric research due to the high risk of failure ...Doctoral Thesis -
The role of the Southern Ocean in the global biogeochemical cycles of cadmium and zinc and their isotopes
(2019)Trace elements, particularly transition metals, are critical for the growth of marine organisms, acting as micronutrients that fulfil vital functions in numerous biological processes. Over the past decades, a rapidly expanding body of research has shown that their oceanic distributions play a key role in controlling primary production in the upper ocean, influence the functioning of ocean ecosystems and impact the global carbon cycle. ...Doctoral Thesis -

Magnetic Catheters for Cardiac Arrhythmia Ablations
(2019)Effective radiofrequency ablation for patients affected by cardiac arrhythmias corresponds to significant and long-term improvements in their quality of life and a significant reduction in the risk of sudden cardiac death. These procedures do not always succeed, primarily due to the inability to precisely and accurately navigate a catheter inside the heart. By enabling the precise control of a flexible catheter using external magnetic ...Doctoral Thesis -

Environmental Assessment of Food Losses and Reduction Potential in Food Value Chains
(2018)In order to enable future generations to lead a decent life, human consumption of natural resources and impacts on the environment must urgently be reduced. A cornerstone among all human activities is food consumption, which is responsible for roughly one third of all environmental impacts of consumption. The food supply chain is inefficient, as present studies estimate roughly one third of the edible food to be wasted globally. There are ...Doctoral Thesis -

Understanding the Value of Travel Time.
(2019)Project appraisal is an essential part of policy making, in transportation and elsewhere. To this end, different valuation methods are used. One of the most important evaluation tool is the Cost-Benefit-Analysis. Often, travel time savings account for the largest share of the gains in Cost-Benefit-Analyses. Therefore, they are a central element of the analyses, making its accurate determination of great importance for transport policy ...Doctoral Thesis -

Part-to-Part Control in Deep Drawing
(2019)The aim of the thesis is to introduce and develop a part-to-part control algorithm which only uses the settings of the press as control variables. As a state variable, the draw-in is evaluated based on simulations. In addition, the simulations of a kitchen sink are chosen as a baseline model for the design of a possible control algorithm. For the baseline model, variant simulations are carried out in AutoForm and LS-Dyna to evaluate ...Doctoral Thesis -

Additive Fertigung in der industriellen Serienproduktion: Bauteilidentifikation und Gestaltung
(2019)Additive Manufacturing (AM), often referred to as 3D printing, is developing very dynamically. The technology and its machines are so mature that additive series production of final components is possible. The digital process chain and in particular the freedom of design are the outstanding properties of the process. If these advantages are properly exploited, serial components can be produced economically - despite the still high ...Doctoral Thesis -
Soft-Sensing, Automation, and Diagnosis for Nitrification
(2019)Nitrification of wastewater requires control for the purposes of efficiency and of stability. However, first, the highly complex microbial community in wastewater treatment plants and very different compositions of wastewaters impede a complete understanding of nitrification. Second, the determination of the states of the process is seldom exact because sensors are subject to a high level of wear and tear. Consequently, instrumentation, ...Doctoral Thesis -
