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 -

Design of an HDPE bottle collection and pre-cleaning system for recycling in Blantyre, Malawi
(2024)Until today, around 3 billion people lack access to municipal solid waste collection. Espe- cially low-income countries struggle with mismanagement of plastic waste. Openly disposed plas- tic materials form a severe risk to humans, animals, and the environment. To mitigate the growing issue of improperly discarded plastic waste in Blantyre, Malawi, a pilot program is being estab- lished by the Chair of Global Health Engineering at ETH ...Master Thesis -
Detection of Contamination in Biowaste
(2024)In the pursuit of a circular economy and the optimization of recycling rates for municipal waste, biowaste, constituting over 34% of Europe’s total municipal waste, emerges as a signifi- cantly overlooked resource. The potential of converting this biowaste into biogas and compost is substantial, offering valuable sources of green energy and fertilization, respectively. How- ever, a central challenge obstructing this potential lies in ...Master Thesis -

A Distributed System for Large Scale Vector Search
(2024)Machine learning (ML) models can encode various types of data as vectors that represent the data semantics. Consequently, vector similarity search is now the backbone of modern information retrieval and machine learning systems. In a search engine, an ML model first encodes the query as a vector. The query vector is then compared against the database vectors, and the ones that are closest to the query are returned. Such search process is ...Master Thesis -
MaRINeR: Enhancing Novel Views by Matching Rendered Images with Nearby References
(2024)Rendering realistic images from 3D reconstructions is an essential task of many Computer Vision and Robotics pipelines, notably for mixed-reality applications as well as for training autonomous agents in simulated environments. However, the quality of novel views heavily depends on the source reconstruction which is often imperfect due to noisy or missing geometry and appearance. Inspired by the recent success of reference-based ...Master Thesis
