Understanding and quantifying the factors determining potential worst-case heat anomalies
(2024)Over recent decades, many unprecedented heat extremes have been recorded, resulting in devastating impacts on the environment, society, and economy. However, while the proximal causes of moderate heatwaves are clear (anticyclonic large-scale flow situations, subsiding air and clear skies, dry soils, and amplified land-atmosphere interactions), the physical processes that differentiate the potential worst-case heatwaves from somewhat ...Master Thesis -
Time Series Analysis in Alpine Environments: Applications in Glacier Length and Snow Height in the Canton of Valais
(2024)This thesis explores the application of time series analysis in alpine and envi ronmental fields with a focus on modeling and forecasting. It aims to address the challenges of identifying appropriate models that strike a balance between complexity and accuracy. Designed as a tutorial, this thesis serves as a practical guide and provides step-by step guidance on analysing environmental time series and implementing them in R. All ...Bachelor Thesis -
Iterative Learning Control for Highway Traffic Control
(2024)In the modern world, congestion on the highway has become a significant social problem due to the increasing number of vehicles. This leads to considerable waste of time and pollution. On the other hand, service stations play an important role in affecting the congestion on highways. In this project, we aim to study the effect of controlling the outflow of the service station on the overall congestion on the highway. Moreover, the vehicle ...Master Thesis -
Computing the Poisson-Binomial Distribution for Soccer Match Outcomes
(2024)In soccer analytics, the Poisson-Binomial distribution is used to obtain the probabilities of the possible match scores of a team. This is an important distribution for analysts, because it allows for construction of new descriptive metrics and further meta-analysis. This work outlines the theoretical background of the Poisson-Binomial distribution, hoists it into the context of soccer analytics, while also providing content on the ...Bachelor Thesis -
Functional Neural Networks
(2024)With the technological advancements in data collection and storage, it is not uncommon to encounter situations where data are observed realizations of some underlying process defined over a continuous domain. Examples of such datasets are often found in finance, acoustics, medicine, engineering and many other disciplines. Functional data analysis (FDA) is a fairly recent field that offers a powerful framework for analyzing such data by ...Master Thesis -

BIM-Based Circularity Assessment for Swiss Architecture Competitions
(2024)This thesis aimed to provide quantitative methods to assess circular construction strategies in Swiss architecture competitions. Its methodology consisted of three steps: Firstly, current practices in architecture competitions were identified. Secondly, current assessment methods were revised and, thirdly, integrated into a BIM-based competition delivery process. Very few Swiss architecture competitions that explicitly targeted circularity ...Master Thesis -
Solving the Elastic Wave Equation with Physics-Informed Neural Networks: A Robust and Critical Assessment
(2024)Physics-Informed Neural Networks (PINNs) have recently emerged as a promising approach for solving Partial Differential Equations (PDEs), offering a meshfree alternative that integrates physical principles into the learning process. This presents a new paradigm compared to traditional discretization methods and purely data-driven machine learning techniques. While promising, PINNs are not a panacea; they inherit challenges such as spectral ...Master Thesis -
Exploring the use of WebAssembly for isolating Functions in Dandelion
(2024)Untrusted code execution is the process of running software that cannot be assumed to execute correctly (bug-freedom) or with good intentions (malware-freedom). Today, untrusted code execution is found in various places, from a web-browser safely running websites on a mobile phone, to a large cloud computing provider running customer workloads on managed hardware and infrastructure. From an operating system perspective, we talk about ...Bachelor Thesis -
Experimental Optimization of a Peristaltic Pump Prototype for Pit-Emptying
(2024)The development of efficient, affordable, and mobile pit-emptying techniques is crucial for providing safe sanitation to people in densely populated areas of urban and peri-urban settlements with no access to sewer systems. A functional test stand for a low-cost, manually built peristaltic pump prototype was constructed and used to evaluate the flow rate performance of the prototype and variations thereof. Different tube sizes, tube ...Bachelor Thesis
