This study investigates the relationship between social investments and public transport. The purpose is to determine the state of knowledge with regards to social investments and public transport, and if possible determine the factors necessary for this to succeed. To outline the concept of social investments within the framework of transport economics, a thorough review of the relevant theory, a

The exponential growth of Big Data, the Internet of Things (IoT), and Large Language Models (LLMs) has significantly increased the computational and energy demands of modern computing systems. In response, research has increasingly focused on alternative machine learning paradigms and hardware architectures that reduce model complexity and computational load. One such paradigm is the Kolmogorov-Ar

Klimatförändringarnas inverkan på nederbördsmönster, i kombination med ökande urbanisering och förtätning av städer, bidrar till en ökad risk för skyfallsrelaterade översvämningar i urbana miljöer. Detta examensarbete syftade till att undersöka hur översvämningsrisken påverkas av fyra faktorer: regnintensitet, andel grönyta uppströms, avstånd till huvudledningsnät samt typ av ledningsnät. Studien Increasing urbanization and changes in rainfall patterns due to climate change lead to an increased risk of cloudburst-related flooding in urban areas. This master’s thesis aimed to examine how the risk of flooding depends on four factors: the rainfall intensity, the proportion of upstream green areas within catchment areas, the distance to the main sewer system and the type of sewer system. The t

Purpose: This study aims to contribute to the understanding of how job-seekers relate their negative recruitment process experiences to brands. Design/Methodology/Approach: This study adopts a qualitative approach using semi-structured interviews, conducted with thirteen current university students actively seeking employment in degree-requiring fields. The data is abductively analysed through th

This thesis investigates particulate matter emissions from a turbofan jet engine operated with fossil Jet A fuel and mixtures of Jet A and sustainable aviation fuel (SAF), focusing on particle size distributions and total emission concentrations. The aim was to evaluate emissions from different fuel blends and sampling points, assess the performance of the designed sampling and dilution system, an

While women comprise the majority of employees in Chinese Environmental NGOs (ENGOs), little is understood about how they navigate leadership within gendered and politically constrained organisational structures. The gap in understanding gendered dynamics in environmental organisations persists, particularly in non-Western contexts such as China. This study focuses on female leaders in Chinese ENG

Modern telecommunications equipment places increasing demands on energy efficiency, driven by both environmental concerns, rising electricity costs, and the strain on national power grids. This thesis investigates practical ways to reduce power consumption in radios, particularly in the downlink digital signal processing chain. Our findings were tested on two platforms, a validation board and an i

Bakgrund: Hemfödsel förekommer i begränsad omfattning i Sverige och planeras årligen av ett mindre antal kvinnor. Att föda på sjukhus utgör normen och barnmorskors råd och stöd utgår vanligen utifrån den sjukhusbaserade förlossningsvården. Denna utgångspunkt kan prägla hur valet att föda hemma bemöts och diskuteras i mödrahälsovården. Tidigare studier visar att kvinnor kan möta ifrågasättande och

Bakgrund: Antalet människor som på olika sätt påverkas av naturkatastrofer, krig eller konflikter ökar. Dessa katastrofsituationer medför att de som drabbas får inskränkt möjlighet att engagera sig i viktiga och meningsfulla aktiviteter. Arbetsterapeuter har kompetens om hur person, miljö och aktivitet samspelar och kan bidra till arbetet i samband med katastrofsituationer och med katastrofdrabbad

This study investigates how varying hyperparameters of the Synthetic Minority Over-sampling Technique (SMOTE) affects the stability of model explanations produced by SHapley Additive exPlanations (SHAP) and Local Interpretable Modelagnostic Explanations (LIME). By using an eXtreme Gradient Boosting (XGBoost) classifier trained on 11 medical datasets with varying imbalance ratios, four SMOTE parame

Syftet med examensarbetet är att undersöka vilka logistiska utmaningar som uppstår vid återbruksprojekt med mer storskaligt återbruk. Examensarbetet har utförts som en kvalitativ fallstudie där data har samlats in via delvis strukturerade intervjuer, en mindre dokumentstudie samt en jämförelse med ett tidigare forskningsprojekt. Intervjustudien utfördes med sju olika respondenter där fem av dem The purpose with the thesis is to analyse what logistical challenges occur in reuse projects with reuse on a larger scale. The thesis was performed as a qualitative case study where the data was gathered from semi structured interviews, a smaller document study as well as a compression to a research paper. The interview study was performed with seven different respondents where five of them had

Forest fires are a natural disturbance in the Swedish landscape. These are largely dependent on meteorological conditions. However, anthropogenic interference and climate change are shifting natural patterns of fire behaviour. The present study examined trends in weather parameters influencing forest fire activity to improve the understanding of changing fire risk in Sweden. Data from twelve weath

Syftet med denna studie var att undersöka sambandet mellan upplevd stress, miljöbelastning och olika former av självtillit inom tre specifika domän; professionell självtillit, social självtillit och romantisk självtillit. En kvantitativ ansats användes för att utforska frågeställningarna: “Vilket samband finns det mellan upplevd miljöbelastning, romantisk självtillit, social självtillit och profesThe purpose of this study was to investigate the relationship between perceived stress, environmental strain, and different forms of self-reliance within three specific domains; professional self-reliance, social self-reliance, and romantic self-reliance. A quantitative approach was used to explore the research questions: “What is the relationship between perceived environmental strain, romantic s

The Period genes (Per) play essential roles in modulating the molecular circadian clock timing in a broad range of species, which regulates the physiological and cellular rhythms through the transcription-translation feedback loop. While the Period gene paralogs are widely observed among vertebrates, the evolutionary history and the functional diversification of Per genes across vertebrates are no

Objectives: Although obsessive-compulsive disorder (OCD) is strongly associated with a range of modifiable somatic health problems, little is known about how the disorder influences the adoption and maintenance of healthy lifestyle habits, as well as how it shapes patients' experiences of seeking and receiving general healthcare. Methods: Sixteen individuals with OCD and cardiometabolic risk who p

Co-occurrence of humans and wildlife leads to interactions with potential positive or negative outcomes for the human actors and for the wild animals. It may also lead to positive or negative interactions between various human actors, who perceive the wildlife or wildlife conservation and management similarly or in different ways. The description of negative interactions as Human Wildlife Conflict
