Practical data-centric optimization of C/C++ applications
(2022)C is a programming language used everywhere and in a big part of scientific codes. With the increase of highly parallel computing machines the code needs to be adapted to be able to use the full power available. In my thesis I will expand a compiler frontend to be able to transform C code into a data centric representation that will intern be able to identify data dependencies automatically and hence produce highly parallel code. ...Bachelor Thesis -
Set-Centric Subgraph Isomorphism
(2021)We investigate techniques for accelerating subgraph isomorphism (SI). SI is the task of finding occurrences of a pattern graph in a target graph and relevant to many practical applications. Our key idea is to use set algebra based formulations of SI. This facilitates employing set data structures to test the feasibility of partial mappings from the pattern graph to the target graph. The methods we use involve a range of algorithm variants ...Bachelor Thesis -
Greening the Internet by putting networks to sleep
(2022)Today’s network topologies are designed to withstand peak traffic and network failures. That results in a more extensive redundancy than needed for operating the network safely during the regular or underused operation. This project aims to determine to what extent redundancy can be reduced without compromising the functionality of the network.Bachelor Thesis -
Potential of VLBI VGOS telescope in Tahiti for geodesy and astrometry
(2022)In the framework of this thesis, the goal is to examine the planned VGOS network, which is currently being developed by the International VLBI Service for Geodesy and Astrometry (IVS). In Very Long Baseline Interferometry (VLBI), groups of radio telescopes are used to observe distant radio galaxies such as quasars to derive important geodetic parameters for scientific purposes. The newly proposed VLBI Global Observing System (VGOS) is ...Bachelor Thesis -
Implicit shape representations for analytically differentiable contact dynamics
(2021)With the advances in robotics and increased research in deep learning, a variety of differentiable physics frameworks have been introduced in recent years. This thesis aims at extending an existing simulation framework with the ability to handle collisions with complex geometries while preserving the property of differentiability. The penalty-based contact model is extended to handle frictional contact for various collision types by ...Bachelor Thesis -
Metapopulation dynamics and the influence of the killer system in a natural S. cerevisiae population
(2022)Populations and their genetic makeup are ever changing. Metapopulations of interconnected small populations, observed over many years, can give us an insight into large-scale shifts in their genetic composition. Here we use a natural metapopulation of Saccharomyces cerevisiae to explore changes in its genetic composition over time. We further examine a possible cause for genetic shifts using the killer-yeast system. We found a large ...Bachelor 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 -
Die Sicherheitspolitik der Schweizer Jungparteien
(2023)Die zunehmende Instabilität der Sicherheitslage im Umfeld der Schweiz und die Rückkehr des Krieges auf europäischen Boden zwingen die politischen Parteien zu einer graduellen Neupositionierung in deren Sicherheitspolitik. Diese Arbeit fokussiert sich auf die Jungparteien («Generation Z»), welche einen historischen Bedeutungszuwachs erleben und in einem als unsicher wahrgenommenen Umfeld aufgewachsen sind, woraus sich die Forschungsfrage ...Bachelor Thesis -
Evaluation of Xilinx Versal Device
(2023)The ”Adaptive Compute Acceleration Platform” from AMD/Xilinx combines a classical FPGA part with a CGRA part, the so-called AI Engines, to open up new ways to increase the performance of powerful computers. While ACAP based devices are now available for end users, it is still unclear what the actual capabilities of these devices are and how to use them most effectively. As the first step of this thesis, we examined the provided API and ...Bachelor Thesis -
