Unravelling the Mechanisms and Characteristics of Supraspinal Motor Fatigability
(2024)Motor fatigability is a common experience in everyday life when we reach the limit of our physical performance. It is also prevalent among athletes, hindering potential for peak performance. Moreover, in clinical settings, heightened motor fatigability serves as a devastating symptom of many neuromuscular and neurodegenerative disorders. Despite its widespread occurrence, surprisingly little is known about the supraspinal processes involved ...Doctoral Thesis -
Exploring the Correlation between Transactional Bugs and Isolation Levels
(2024)This thesis aims to create a testbed for easily replicating and analyzing Database Management System (DBMS) transactional or isolation bugs, use this testbed to replicate and analyze a set of known bugs, and develop a novel bug-finding tool. The final objective is an end-to- end testing framework researchers can use for finding, replicating and understanding DBMS isolation bugs. First, we create a testbed leveraging containerization ...Master Thesis -
Drivers and scales of landscape transience in the Hengduan Mountains, China
(2024)Landscape evolution in mountainous regions is a dynamic, continuous process modulated by interactions between external forces, such as tectonics and climate, and physical processes at the Earth’s surface. On long timescales, landscapes trend towards a quasi-steady state, where rates of surface erosion compensate for the movement of the underlying bedrock. This is achieved through adjustments to the steepness of hillslopes and rivers, with ...Doctoral Thesis -
Towards the absolute AMS Measurement of 32Si/28Si
(2024)The half-life of the radioisotope $^{32}$Si is currently imprecisely known (153 $\pm$ 19 y). Therefore, the SNF-funded project SINCHRON ($^{32}$Si: a new chronometer) was initiated with the goal of accurately redetermining the half-life using artificially produced sample material and combining multiple independent methods. In this work, the absolute accelerator mass spectrometry (AMS) measurement of $^{32}$Si/$^{28}$Si ratios of ...Doctoral Thesis -

ELECTROCHEMICAL TOMOGRAPHY - A NEW NDT TECHNIQUE TO DETECT AND QUANTIFY LOCALIZED CORROSION IN POROUS MEDIA
(2023)Localized corrosion in porous media, such as reinforcing steel corrosion in concrete, is one of the main reasons of premature degradation of engineering structures. Especially in the field of civil infrastructure, where the use of reinforced concrete is abundant, localized corrosion is very problematic. High local corrosion rates can lead to a fast local loss of the steel cross-section, which often only becomes visible on the concrete ...Doctoral Thesis -
Efficient and Lightweight Localization, Perception, and Mapping for Resource-Constrained UAVs
(2024)The field of autonomous robots has experienced significant growth in the past decades, attaining a level of maturity where robots can perform sophisticated tasks in challenging and dynamic environments, occasionally surpassing human capabilities. In the last years, research endeavors have increasingly focused on constrained robotic platforms such as nano Unmanned Aerial Vehicles (UAVs) that weigh only a few tens of grams. The capabilities ...Doctoral Thesis -
Magnetic Frustration and Improper Ferroelectricity in Multiferroics
(2024)This thesis presents a comprehensive theoretical investigation of the interplay between ferroelectricity, magnetism, and crystal structure primarily in the class of R MnO 3 (hexagonal manganites, RMO), as well as in MnWO 4 (manganese tungstate,MWO), with a focus on both their ground and excited states. The strong coupling between structure, ferroelectricity, and magnetism in multiferroic materials gives rise to many potential avenues for ...Doctoral Thesis -
Regionalized life cycle assessment of lithium carbonate production from brines
(2024)As lithium (Li) powers the transition to a low-carbon society through the expansion of energy storage technologies, it is crucial to understand its environmental impacts. This thesis examines the environmental impacts of Li extraction and processing. Meeting the soaring demand for Li requires substantial increases in primary and secondary supply. The global supply is concentrated in a few countries and is dominated by pegmatites (57 %) ...Doctoral Thesis -
Quantifying subsurface water movement in a reforestation initiative through geophysical monitoring
(2024)Climate change is expected to exacerbate water scarcity in regions with semi-arid regions. In Tamil Nadu, India, where current water use already exceeds renewable supplies, the local NGO Sadhana Forest (SF) has worked to raise the groundwater table through reforestation and the installation of water retention structures. This master’s thesis investigates the impact of one such structure frequently built by SF, an on-contour swale, on ...Master Thesis
