This thesis investigates model-based electromagnetic comparability (EMC) of an IGBT-based two-level voltage source converter (VSC). The main focus lies on common-mode and differential-mode behaviour through conducted electromagnetic interference (EMI). The study centres around the Active Dynamic Filter P25 developed by Comsys AB, which serves as the converter under test (CUT). Conducted emissions
The importance of Disaster Risk Management (DRM) is growing as global risks increase and more actors implement DRM strategies. However, the unpredictable and complex nature of disasters and other risks makes it difficult to train DRM skills in advance. Serious games, which are games designed for educational purposes, offer a promising way to build these skills by simulating real-world challenges i
Background: The beauty industry has transitioned away from traditional marketing and toward interactive, social media-driven techniques, with firms engaging customers with influencers and user-generated content on platforms such as Instagram and TikTok. While most studies focus on advertisements and influencers, little is known about how average users, particularly young women, interact with beaut
Humanitarian aid workers (HAWs) face increasing risks in conflict zones, with 2024 marking the deadliest year on record. International humanitarian organisations (IHOs) must address this trend to continue delivering aid and protecting HAWs. This study investigates how IHOs adapt to the evolving risks in these contexts and explores challenges that adaptation measures may entail. A qualitative resea
Att göra städer grönare är en central strategi för klimatanpassning i allt varmare urbana miljöer. Många studier undersöker säsongsvariationer i urban fenologi, men det är mycket få av dem som fokuserar på kontinuerliga och dynamiska fenologiska mått. Denna studie analyserar sambandet mellan Plant Phenology Index (PPI) och markytetemperatur (Land Surface Temperature, LST) i Bryssel under år 2022, Urban vegetation is a key strategy for climate adaptation in increasingly dense and warming cities. While some studies look at urban seasonal trends in plant phenology, fewer look at continuous dynamic phenology measures. This study investigates the relationship between the Plant Phenology Index (PPI) and Land Surface Temperature (LST) across Brussels in 2022, using satellites Sentinel-2-derived P
In 2016, after decades of armed conflict, the Colombian government signed a peace agreement with the Revolutionary Armed Forces of Colombia – People's Army (FARC - EP). Nevertheless, the hopes for peace have not been realised, since violence, assassinations of social leaders, displacement of local communities and environmental degradation still occur. New groups are taking over the areas forme
Nanowire quantum dots have shown promise as energy filters in thermoelectric applications. However, anomalous effects in the thermocurrent have been observed when heat is applied in close proximity to the quantum dot. This work began as an experimental investigation but transitioned to a data analysis project due to hardware failure. Using previously acquired experimental data, we compare the meas
Digital platforms have become a crucial tool for career planning, especially for young people in the beginning of their careers. Today’s students must navigate numerous career options while adapting to new digital norms around personal branding and showcasing success. These platforms provide valuable opportunities for inspiration and building a professional identity, enhancing career planning. How
This research is a part of a new, up and coming field in exploring differential dynamic microscopy (DDM) as a method for research in biomaterials. DDM is a method that enables the possibilities of working with non-transformed images in real time while still providing information about the dynamics without the need for complex optics or lasers. The analysis is possible through the Fourier Transform
The Swedish healthcare system is facing a substantial challenge in competence provision, with skilled staff needed in both the private and public sectors. The Swedish government is investing heavily in initiatives and mapping projects aimed at securing future competence supply. This study aims to identify which factors have the greatest impact on healthcare employees' decisions to either leav
Den svenska demografin förändras och antalet invånare äldre än 64 år väntas öka de kommande åren. Dessutom har urbaniseringen förändrats något, inte minst efter pandemin, då utflyttningen från storstäder till mindre orter ökat. Ökad flexibilitet i många yrken och delvis ändrade levnadsmönster har således resulterat i ett delvis minskat lägesberoende. Sammantaget står fastighetsmarknaden inför föräThe purpose of this study is to investigate what urban life really is and if (and in that case also how) urban life may be created and affected, primarily during the asset management phase. The study is conducted from the landowner’s perspective. Furthermore, the study aims at exploring what consequences and impact urban life has on the attractiveness and value of a place. The study is based on a
This thesis aims to examine how equity markets responded to Donald Trump’s 2024 election victory, focusing on industries targeted by his proposed policy agenda. It seeks to identify differences in returns and trading activity, and to provide insight into how political signals influence investor expectations and behavior. This thesis demonstrates that policy-favored firms realised significantly hig
This thesis investigates the integration of the individual learning rates from Rprop into SGD and Adam optimization methods. The individual learning rates are updated separately from the weights. A major focus of this work is the role of mini-batch size in updating these learning rates. Empirical analysis demonstrates that selecting an appropriate mini-batch size can accelerate convergence and imp
We consider two-dimensional travelling water waves over flows with constant vorticity and critical layers. We use global analytic bifurcation theory to show the existence of a global curve of solutions which either approaches a solitary wave or forms a critical point along the surface. In contrast to most of the previous studies, we fix the Bernoulli constant and use the wavenumber as a bifurcatio
This thesis investigates how immigrant tour guides negotiate identity and belonging through the act of guiding tourists from their country of origin in their country of residence. The study frame tours not merely as cultural encounters but as performative and affective spaces of self-representation. Focusing exclusively on the guides’ perspectives, it draws on semi-structured interviews with immig
This research characterized the barrier properties and transport mechanisms of multilayer films comprising polylactide (PLA), chitosan, and nanocelluloses extracted from agricultural by-products. The investigation employed complementary analytical techniques to evaluate water vapor and oxygen transport behavior, comparing cellulose nanofibers (CNF) and cellulose nanocrystals (CNC) derived from cor
This thesis examines the scope of the law of State immunity from enforce-ment, with the intention of determining if the frozen assets and reserves of the Central Bank of Russia can be confiscated without implicating State immuni-ty. State immunity from enforcement has its legal basis in customary interna-tional law and is generally understood to protect State property from being subjected to pre-
