Ever since the end of the second world war, Europe has been lagging behind the United States in rocket development. In particular in the last 10 years, the technological gap and American competitive advantage have grown thanks to SpaceX’s development of reusable launch vehicles. A key enabler for the reusability of booster stages is precise rocket engine control. This thesis addresses the objectiv
Climate change and its environmental consequences is a pressing global challenge, with the construction industry being a major contributor to carbon dioxide emissions. This has led to an increased interest in biobased insulation materials, such as hemp fiber and wood fiber, which offer more sustainable alternatives. However, questions arise regarding their fire performance, particularly when repl
Today, most software systems are event-driven, meaning that code execution is triggered by events handled dynamically. A typical example is a graphical user interface, where a button click initiates a specific action. In contrast, classic automation systems rely on programmable logic controllers, which execute code periodically at fixed intervals. The purpose of this study is to compare periodic a
This thesis explores the causal relationship between exogeneous price shocks on commodities and the level and intensification of violence in the Democratic Republic of the Congo during the year 1989 to 2023. To empirically test this relationship, fixed effects regression models has been used to analyze the effects of these shocks across the 26 provinces that makes up the Democratic Republic of the
Artificiell intelligens blir alltmer populärt och används idag från allt till datorseende och självkörande bilar till chatbot assistenter som OpenAI:s världskända ChatGPT. Kärnan bakom dagens stora boom i artificiell intelligens är neurala nätverk, som blev möjligt att använda på grund av en stor utveckling i uträkningskraft med grafikkort. Neurala nätverk behöver astronomiska summor med uträkningAs deep neural networks grow more powerful, they also require more computational resources, which becomes a challenge when deploying on edge devices with limited computational capacity. This thesis looks into knowledge distillation, a model compression technique where a large "teacher" network transfers its learned features to a smaller "student" network. Our goal is to maintai
This thesis studies the impact of the war in Ukraine on stock prices of firms within the European defense industry. While previous studies have examined the effects of war on stock prices of defense firms, fewer studies specifically focus on the war in Ukraine. Furthermore, this thesis focuses solely on European defense firms, offering a new geographical perspective to the topic. Additionally, the
Projektet Sankt Görans Koloni är en undersökning av hur odling och gröna mötesplatser kan användas för att ena en splittrad stad. Projektet är en odlingsförening, park och kulturcentrum i centrala Landskrona.
The purpose of this study is to map Key Performance Indicators (KPIs) related to the operation and maintenance of photovoltaic (PV) systems, i.e., solar cells, on commercial buildings. This is investigated through a literature review aimed at gathering and evaluating relevant KPIs. A total of 24 KPIs are identified in the literature review. After evaluation, a selection of these KPIs is used to an
This thesis analyzes securitization of the Swedish aid strategy in Palestine, through exploring the influences of security discourse on governance and allocation of Swedish development cooperation and humanitarian assistance in the region between October 7, 2023 - October 7, 2024. The research is approached as a case study and Carol Bacchi's (2009) “What's the Problem Represented to Be” (W
Land use has a major influence on the nutrient balance in a region. Land use changes such as the restoration of peatlands can therefore have an impact on it. In this analysis, nutrient exports in the Baltic Sea basin and in some regions of the North Sea basin were estimated under different future scenarios including scenarios that promote land use changes such as peatland restoration through CO2 p
This thesis highlights the need for quality assurance of the Swedish preschools by regulating structural factors. Attending preschool has proven to have positive effects on both children and society, provided that the preschool maintains a high quality. In comparison, if the quality is poor this might result in negative or harmful effects. Various movements have indicated that the Swedish preschoo
Titel: Fenomenet underprissättning av IPO:s – En undersökning av möjliga orsaker Seminariedatum: 2025-01-17 Kurs: FEKH89, Examensarbete i finansiering på kandidatnivå, 15 hp Författare: Anton Lydén, Martin Broander, Mohammed El Khatib Handledare: Zahida Sarwary Nyckelord: IPO, Börsnotering, Underprissättning, Regressionsanalys, Aktier. Forskningsfrågor: (1) Finns det några statistiskt signif
Detaljerade data är avgörande vid karaktärisering av komplexa förorenade områden. I denna studie utrustar vi ett antal G360-brunnssystem med Star-Oddi milli-TD-tryckgivare i ett mestadels PCE (tetrakloretylen)- och TCE (trikloretylen)-förorenat bostadsområde i Helsingborg. Trots att dessa tryckgivare vanligtvis används inom marina undersökningar gör deras kostnad samt kompakta storlek dem av intreHigh-detailed data are key when characterizing complex contaminated sites. In this study we instrument Star-Oddi milli-TD pressure transducers in G360 multilevel groundwater monitoring systems within a mainly PCE (tetrachloroethylene) and TCE (trichloroethylene) contaminated residential area in Helsingborg, Sweden. Despite these transducers being typically utilized in marine research, their afford
The circumstances and constraints under which a problem is solved can affect how people engage in problem solving. Based on that premise this research investigates the effects of motivational music in the context of a dynamic ball-transportation task. In particular, this study explores how music influences distance moved, throwing accuracy, non-linearity, motivation and emotion regulation. 15 part
Hearing loss is increasing with an ageing population. There is thus a need for more convenient diagnosis methodology. This thesis investigates whether it is possible to classify age-related hearing loss using speech biomarkers and Automatic Speech Recognition (ASR) or not. The methodology was a binary classification problem based on analysing conversational data between a participant with normal h
This thesis explores the potential effects of universal basic income on labor supply and leisure allocation among employed individuals in Sweden. Grounded in the standard neoclassical labor-leisure framework, the study utilized an online survey targeting Swedish workers to investigate whether a monthly universal basic income of 12,208 SEK would reduce working hours and how individuals might reallo
Sverige anses vara ett jämställt land, där kvinnor och män har lika värde och rättigheter. Både genus och jämställdhet är begrepp som är beforskade, och organisationer säger sig arbeta aktivt mot mer inkluderande arbetsplatser. Men trots detta finns det stora klyftor i arbetslivet, där kvinnor inte har lika villkor som män, där strukturer och kulturer är hinder för kvinnors möjlighet att avancera.
Det ställs allt högre krav på räddningstjänster i Sverige idag, till följd av en föränderlig värld. Detta innebär att räddningstjänsterna behöver vara beredda på alla möjliga typer av händelser, som exempelvis skogsbränder, översvämningar, krig eller spridning av farliga ämnen. För att ha kapaciteten att hantera denna typ av frågor behövs ofta en större storlek, vilket har gjort att sammanslagning
This thesis investigates the causal relationships among alarms at the European Spallation Source (ESS), focusing on enhancing alarm management through advanced data analytics. The study explores these relationships using Dynamic Bayesian Networks (DBNs) complemented with well-defined Conditional Probability Distributions (CPTs). This approach models the cascading interactions of alarms based on th
