Over-frequency has become an increasingly relevant issue in the Nordic synchronous power system, mainly because of the increased number of HVDC (High Voltage Direct Current) links connecting it to neighboring synchronous systems. The aim of this thesis is to research the impact that over-frequency events, caused by faults in HVDC links, have on the Nordic power system and especially what frequenci

Bakgrund: Kvarstående funktionedsättningar efter stroke begränsar individens förmåga att utföra aktiviteter i dagliga livet. Aktivitetsbaserade interventioner med fokus på meningsfulla aktiviteter har visat sig förbättra aktivitetsutförande, men används i begränsad omfattning av arbetsterapeuter. Syfte: Kartlägga aktivitetsbaserade interventioner som arbetsterapeuter använder för att främja aktivBackground: Remaining impairments after stroke limit the individual´s ability to perform activities in daily life. Occupation-based interventions focusing on meaningful occupation have been shown to improve occupational performance but are used to a limited extent by occupational therapists. Aim: To chart occupation-based interventions that occupational therapists use to promote occupational perf

This thesis investigates market inefficiencies in Chapter 11 bankruptcy stocks, focusing on whether short-term momentum can yield positive returns.

Denna studie undersöker hur finansieringsmetoden vid företagsförvärv påverkar långsiktig aktiekursutveckling bland svenska börsnoterade bolag. Studien är kvantitativ och bygger på data från 148 M&A-transaktioner under perioden 2010–2020, insamlade från Orbis, Nasdaq och årsredovisningar. Med OLS-regressionsanalys testas sambandet mellan finansieringsmetod och abnormal aktiekursutveckling. ResThis study examines how an acquiring company’s choice of financing—debt, equity, or a combination—affects long-term stock performance after mergers and acquisitions among Swedish publicly listed firms from 2010 to 2020. Analyzing 148 transactions, we found no clear link between financing method and long-term stock returns. Even when considering transaction value relative to company size, no signi

Background: Psilocybin-assisted therapy (PAT) shows promise in the treatment of a variety of mental disorders. To date, no meta-analysis has been conducted on the effect of PAT on quality of life (QOL). Methods: A systematic review and meta-analysis of clinical trials examining PAT and reporting on QOL, extracted from Embase, Medline, PsycInfo, Web of Science and Cochrane CENTRAL. Results: Across

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

Detta examensarbete undersöker möjligheter och utmaningar med sjukresor i Sverige, med fokus på hur olika regioner hanterar transporter för patienter samt de problem som finns kopplade till tillgänglighet och kostnadseffektivitet. Studien syftar till att jämföra regionernas regler och krav för sjukresor samt att utvärdera tillgängligheten i den ordinarie kollektivtrafiken i Skåne. Om den allmänna This thesis investigates the opportunities and challenges of patient transport services in Sweden, focusing on how different regions manage transportation for patients and the associated issues of accessibility and cost efficiency. 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
