Ett allvarligt hot mot säkerheten, tillförlitligheten och ekonomin inom den nationella och globala järnvägsinfrastrukturen är bränder. Detta examensarbete har som syfte att undersöka olika orsaker till dessa bränder samt hur risken för de kan förväntas öka längs järnvägsinfrastrukturen i Sverige med tanke på klimatförändringarna. I en omfattande analys av data från Myndigheten för samhällsskydd ocFires along the railway infrastructure pose a serious threat to the safety, reliability and the economy, both nationally and globally within the railway industry. This thesis aims to examine the main causes of these fires and how climate change is expected to increase the risk of them along the railway infrastructure in Sweden. An extensive analysis of data from the Swedish Agency for Community Sa
This study explores the overconfidence bias effect on stock market dynamics in Sweden and the US. Using an OLS model with lagged variables during the period 1996-2023, the findings reveal significant delayed effects of overconfidence on the Swedish stock market. Gender- adjusted overconfidence measure provides limited explanatory power, while the volatility index highlights the high correlation be

The study aims to compare regional regulations and requirements for patient transport while also evaluating the accessibility of public transportation in Skåne. If regu
While studies on the relationship between health, income, healthcare spending and productivity is generally consistent, little attention has been brought to the regional contexts. Meanwhile, a country like Sweden who is generally known for a well-established healthcare system and welfare state, experiences increasing regional disparities. This thesis investigates the relationship between health, i
En studie av hur skuldsättningsgraden påverkar aktiemarknadens reaktion på negativa vinstvarningar. Syftet är att analysera sambandet mellan skuldsättningsgrad och aktiekursreaktion, med ett särskilt fokus på hur skuldsättningsgrad mäts. För att besvara forskningsfrågan genomförs en kvantitativ analys av 121 vinstvarningar från svenska börsbolag under perioden 2021–2024, där en evenstudie används
An extensive public health literature has linked the low take-up of healthcare services in developing countries with measures of accessibility such as distance, duration and cost of travel to the nearest health facility. However, causality has been difficult to prove, given the endogeneity of factors influencing access, such as the availability and quality of roads and transportation. Using a natu
This study examines how descriptive, predictive, and prescriptive analytics are applied in decision-making during stable operations and disruptive events, focusing on the Swedish food retail sector during the Covid-19 pandemic. Using a qualitative case study approach with semi-structured interviews and pattern-matching analysis, the research reveals key differences in analytics usage. During stabl
The aim of this Master Thesis was to develop an anti-slip controller for a small single person electric vehicle to prevent slipping during acceleration. Due to limited space on the vehicle it is not possible to fit sensors for measuring the vehicle’s speed, and thus the traditional way of calculating slip by comparing wheel and vehicle speed is not possible. Another difficulty was the fact that th
Populationen av västerländska akademiker och studenter visar tecken på ideologisk bias i termer av sin sammansättning och villighet att självcensurera. Denna studie undersökte en svensk population av studenter (N = 89), huvudsakligen från samhällsvetenskapliga områden, i termer av ideologi (Moral Foundations; MFQ-20 och Social Dominance Orientation; S-SDO). Studien undersökte också relationen mellThe population of western scholars and students shows signs of ideological bias in terms of its composition and willingness to self-censor. This study surveyed a Swedish student population (N =89) of predominantly social scientists on ideology (Moral Foundations; MFQ-20 and Social Dominance Orientation; S-SDO). The study also explored the relation between self-censorship (SC), age, gender and univ
Bakgrund: Den kulturella mångfalden i Sverige har ökat under de senaste decennierna, främst som en konsekvens av migration. Denna utveckling påverkar hälso- och sjukvården, som möter en alltmer varierad befolkning. Socioekonomiska och kulturella skillnader har en inverkan på tillgången till vård och på vårdens kvalitet. Det anses nödvändigt att vården anpassas för att kunna bemöta de skiftande beh
That an additional tariff of 25 percent could go unnoticed in global trade might seem unlikely, but the findings of this study suggest exactly that. Against the backdrop of escalating trade tensions between the EU and the US, this study examines both the immediate and short-term effects of the EU's temporary additional tariff of 25 percent on the import of exercise equipment. By focusing on th
Täppt näsa, halsont och nysningar är symtom du säkert har upplevt vid en förkylning. Förkylningar är vanligast under våren och hösten och orsakas oftast av Rhinovirus. Även om en förkylning oftast är en lindrig åkomma för de flesta så kan den ha allvarliga konsekvenser för personer med nedsatt immunförsvar eller underliggande sjukdom. Förkylning sprids via direktkontakt, indirekt kontakt (såsom Airborne viral diseases have long been neglected but with the recent devastating impact of the COVID-19 pandemic serving as a catalyst for new science, additional viruses are examined. This thesis investigates the infectivity of Rhinovirus, the virus causing common cold, in differently sized bioaerosols. The experimental setup utilized a bio-aerosol nebulizing generator (BANG) to generate droplets
This paper investigates the application of a Long Short-Term Memory (LSTM) model to construct a forward-looking risk factor for asset pricing. The LSTM model's predictions are utilized to create a novel risk factor, derived from long-short portfolios, offering an innovative approach to decomposing asset returns. For comparative analysis, the Fama-French three-factor (FF3) and Carhart four-fact
Den europeiska textilindustrin står inför stora förändringar när EU:s nya förordning "Ecodesign for Sustainable Products Regulation" (ESPR) träder i kraft. En central del av regleringen är förbudet mot förstörelse av osålda konsumentprodukter, en åtgärd som syftar till att minska miljöpåverkan och öka hållbarheten inom modeindustrin. Studiens mål är att undersöka hur textilindustrin förbStatistics show that approximately 2,71 billion people have at some point shopped for clothes online (Sellers Commerce, 2022). E-commerce is becoming more and more common rather than to buy and try on clothes in a physical store which has led to many clothes being returned for various reasons (poor fit, free returns, etc.). The fast fashion industry generates significant textile waste, with unsold
Nya katalysatormaterial för vätgasproduktion I kampen mot de pågående klimatförändringarna behöver vi byta ut fossila bränslen mot hållbara alternativ. Med hjälp av avancerade mikroskop kan man studera nya partiklar som kan bli viktiga i framställningen av förnybart bränsle. Ett attraktivt alternativ på förnybart bränsle är vätgas, eftersom det enda utsläppet som bildas vid förbränningen är vattAchieving efficient production of hydrogen through the hydrogen evolution reaction is an attractive source of non-fossil fuel. However, this reaction is inefficient and therefore requires catalysts with the most commonly used one being Pt. Due to the high cost and rarity of Pt, research into alternative catalyst materials such as transition metal phosphides has been conducted in the recent years.
Economic sanctions, a key foreign policy tool in global diplomacy, present both challenges and opportunities, yet relatively underexamined in scholarly research. Unlike previous sanctions aimed at natural resources, the US-China trade war targets labour-intensive manufacturing, creating unique opportunities for investment relocation to labour-abundant countries. Vietnam’s success in attracting sub
Recent research in organo-metallic cages composites (MOCs); discrete, self-assembled coordination compounds; has highlighted their significant potential in host-guest chemistry and catalysis. New studies focus on synthesizing multifunctional MOCs by combining more than one ligand. However, due to the unpredictable nature of coordination-driven self-assembly, intricate strategies were imperative to
