The search for non-invasive tools to monitor stress has gained significant research attention. Heart rate variability is one such measure commonly analyzed in either the time domain or the frequency domain. This project explores the use of time-frequency analysis, specifically the spectrogram, for this purpose. The study utilizes real data obtained from a cold pressor test and a control session. O
This study examines the potential link between the digital media discourse of the Nordic Resistance Movement (NMR) and the radicalization trajectories of lone-actor perpetrators. Through interpretive content analysis of NMR's digital media utilizing the theory of intertextuality, and the case studies of three lone-actor perpetrators in Sweden, the study seeks to identify similarities and poten
Soccer is witnessing technological advancements in a variety of areas, of which many are dependent on camera calibration. This thesis addresses the challenge of calibrating the extrinsic parameters of cameras used in soccer broadcasts using a monocular view of the field. Accurate camera calibration is essential for various applications such as player positioning, field modelling, and improving the
Uppsatsen undersöker de oberoende, medelstora förlagens villkor på en bokmarknad där just medelstora förlag i allt större utsträckning köps upp av de större koncernerna, läggs ner eller ändrar utgivningsprofil. I uppsatsen intervjuas tre representanter från oberoende, medelstora förlag om deras självupplevda situation, samtidigt som en dokumentanalys av aktuella kulturpolitiska dokument görs för a
Pluvial flooding is a significant and growing issue in Kampala, Uganda, driven by increased urbanization, lack of sufficient maintenance of the urban drainage system and climate change. This study investigates the impact of sediment and solid waste deposition on urban flooding within the upstream part of the Lubigi catchment area. Using PCSWMM, a 1D hydraulic model was developed to simulate variou
In this thesis, a finite square Moiré system placed inside an optical cavity was simulated. Two commensurate angles, θ = 0 and θ ≈ 37 were considered. The fluorescence spectrum was obtained for both angles and for systems with one particle or two particles with opposite spin. The twisted configuration was found to have a richer fluorescence structure compared to the aligned configuration, which ex
Belgium is celebrated for its progressive LGBTI legislation, ranking second on the ILGA index. At the same time Belgian LGBTQIA+ people experience alarmingly high rates of violence and fear. This thesis examines two competing narratives about the relationship between LGBTI legislation and LGBTQIA+ experiences of safety: (1) ‘LGBTQIA+ safety requires state protection’; and (2) ‘LGBTQIA+ safety requ
This thesis investigates the effectiveness of step size control in the numerical simulation of Stochastic Differential Equations (SDEs). The study is divided into a theoretical exploration and a series of numerical experiments. The theoretical section introduces key definitions and theorems, delves into the properties of Brownian motion, and examines the conditions under which solutions to SDEs ca
The current climate crisis is pressuring policymakers to outline what a post-fossil economy might entail. In Norway, many have pointed towards the salmon farming industry as a central part of the country’s green transition. At the same time, the industry has shifted towards increasing use of feed imports from Brazilian soy plantations - the second largest driver of deforestation in the country. Ex
I detta arbete diskuterar jag problematiken kring olika radiometriska dateringsmetoder samt möjligheten att generera noggranna och precisa dateringar. Goda dateringar av nedslagskratrar är en förutsättning för att undersöka intensiteten av nedslag på vår planet, korrelationen till massutdöende eller de hydrotermala system som uppstår efter ett nedslag och pågår i tusentals år. Problem relaterade tIn this study, I discuss the issues related to radiometric dating methods and the possibility of generating accurate and precise ages. Such dating of impact craters is crucial for investigating impact intensity, correlation with mass extinctions, or the hydrothermal systems that form after an impact and last for thousands of years. Problems related to both analytical and geological causes can resu
A lack of somatostatin expressing interneurons (SST INs) is known to be a factor in several neurodegenerative and neurospsychiatric diseases, such as Alzheimer disease, Parkinson’s disease and schizophrenia. Being able to efficiently obtain SST INs in vitro could enable a greater understanding and better treatment of these diseases. The development of SST INs is not yet fully understood, but it is
This thesis investigates the feasibility and efficacy of employing unsupervised semantic segmentation for classifying features in CALIOP data, aiming to address significant bias inherent in current classification methods. By exploring various preprocessing techniques, dimensionality reduction methods, and classification algorithms, the study evaluates the potential of semantic segmentation in impr
This thesis examines the experiences of LGBTQIA+ persons in Latin America, when they are targeted with hate violence. The study is based on 21 in-depth, qualitative interviews from persons affiliated with IRCA CASABIERTA, a non-governmental organization in San José, Costa Rica, working with LGBTQIA+ migrants, typically from other Latin American countries. The study works through a post structural
CityGML is an important standard to present 3D geometry, topology, semantics and appearance that together with 3D city models, which have had increased use within analysis and applications, such as emergency response, energy consumption and occupancy measurement. However, the standard’s querying and integration capabilities can still be further explored. One way to do this is through the Semantic
This study explores entrepreneurial marketing (EM) and resource based view (RBV) in the context of indirect customer relationship creation in the children's products industry, specifically focusing on how firms navigate regulated markets. Through qualitative, in-depth interviews with business actors, the research has unearthed strategies companies employ to ethically and effectively engage an
A historical narrative of statare: Portrayals in the trade union paper Lantarbetaren In Sweden, a system of married agricultural contract workers paid in kind, known as statarsystemet, persisted until the mid-20th century. These workers (statare) are understood as a highly socially vulnerable group in Swedish history, portrayed in fictional literature as well as in TV series. This thesis addresse
The ongoing war in Ukraine has inflicted wide ranging environmental damages, each with their own set of consequences. The catastrophic failure of the Kakhovka Hydroelectric Dam on the 6th of June 2023 initiated a new cascade of environmental destruction, as hundreds of square kilometres were rapidly inundated, with hundreds more left dehydrated as the Kakhovka reservoir drained away. Within the af
This paper investigates two facets of corporate cash holdings in firms listed on the Stockholm Stock Exchange over the period 2001−2020. Firstly, I examine the determinants of corporate cash holdings. I find that firms with more investment opportunities and smaller firms tend to hold more cash. Firms with controlling shareholders and firms with high institutional block holdings tend to hold less c
