This master thesis explores the neural encoding of speech features for hearing aid users. The study utilizes electroencephalography (EEG) and audio data from an experiment that stimulates a Cocktail Party scenario. This is a complex auditory scene, especially difficult for individuals with hearing impairments. The primary objective of the study is to investigate how different acoustic and linguist
In this project, I investigate the combination of Natural Language Processing (NLP) with Item Response Theory (IRT) to advance the assessment and scoring of open response items. Traditional psychometric assessments are grounded in well-defined quality standards, yet assessments based on natural language have missed meeting these standards. To address this gap, I integrate NLP processed open respon
Recent years of reoccurring heatwaves in urban areas have led to an awareness of the negative effect heat can have on people and ecosystems. Trees play an important role in cooling urban areas but need to maintain their vitality to do so. Therefore, this paper aims to investigate the resilience of the tree community in Malmö from the perspective of an increased mean annual temperature (MAT). In th
With increasing country-level gender equality, country-level gender differences in personality are found to increase. This is known as the Gender-Equality-Personality-Paradox (GEPP). Possibly, the GEPP is a methodological artefact. So far, the personality trait scoring method has not been investigated as a potential source of the GEPP. Three kinds of scores were investigated in the present study:
A lack of full scalar measurement invariance (MI) across groups of test takers is widely assumed to render sum scores incomparable between groups. Computing factor scores from partial-scalar-MI models has been proposed as a remedy. To what extent this scoring method affects personality assessment in diagnostic contexts has yet not been investigated. The present master thesis explored this question
Titel: ‘’EMV vs. A-brands - kampen om den bästa placeringen’’ - en studie om hur produktplaceringar påverkar detaljister och leverantörer samt hur utvecklingen av EMV håller på att förändra livsmedelsbranschen.

The kraft pulp bleaching process presents significant operational challenges due to its inherent non-linear reactions and unpredictable delays, complicating effective control and optimization. This thesis aims to improve the efficiency of the process through modeling it, and lays the groundwork for a new and improved automatic model-based control system. It explores a way of handling the varying d
The control of large and complex systems is a difficult but important topic. In applications, centralized control, in which all measurements about a system are used to compute control actions, is often preferable, since it allows for a better overview of the system and more precise control. However, in large networks, where the complexity of implementing a centralized controller becomes too diffic
This study examines the long-term performance of Swedish Initial Public Offerings (IPOs) from 2000 to 2023. Employing Cumulative Abnormal Returns (CAR) and Buy-and-Hold Abnormal Returns (BHAR) methodologies, this study analyze the impact of market cycles on IPO returns. The findings reveal overperformance of Swedish IPOs during a three year period. Additionally, the research analyzes the influence
Motivated by the textile industry pollution and its responsiblity for 10% of the worlds CO2 emissions, the project set out to explore solutions to textile waste patterns from an industrial designers point of view. Through research, system design, user journey design, material mechanics innovation and product design - three outcomes were generated. 1. An imagined system solution that proposes texti
The fall of Yugoslavia in the 1990s led to a series of political upheavals, culminating in the 1992 referendum in Bosnia and Herzegovina. This referendum triggered the Bosnian War, which was finally ended by the Dayton Peace Agreement signed on December 14, 1995. The Dayton Peace Agreement aimed to stabilize the country by establishing a power-sharing arrangement among its three ethnic groups - Bo
I den här studien analyseras texter som riktar sig till personer som är utsatta för eller utövar våld i nära relationer. Syftet med studien är att ta reda på hur språket kan påverka relationen till läsarna i texterna. Materialet i studien består av sex webbtexter, där tre texter riktar sig till våldsutsatta och tre texter till våldsutövare. Materialet analyseras med utgångspunkt i systemisk-funkti
The integration of renewable energy sources into modern power grids necessitates the use of power electronic converters capable of handling high voltages. Multilevel converters offer advantages compared to traditional 2-level converters by provid- ing multiple voltage levels, improved efficiency, and better power quality. However, maintaining balanced DC link voltages presents additional complexit
This project is focusing on one of the underlying issues within the plumbing industry (called “Värme Ventilation Sanitet” in Sweden). Strain injuries was the focus of this project to find a solution and discover the reasons to why these injuries keeps happening. The project then goes into a suggestion of which direction the industry might need to take to become better. Getting a solution to the in

In the capitalist system, there is a need to envision alternatives that advocate for a more just and sustainable world. Alternative scholarships, such as degrowth, aim to counter the hegemonic narrative of food commodification by promoting practices that put social and environmental well-being at the forefront. This ethnographic research outlines the alternative strategies of tackling food waste a
This study will examine how fashion consumption looks on Tiktok among young women aged 18 - 19 years in Sweden. The aim is to find out which factors influence the target group's fashion consumption on Tiktok and in which specific ways Tiktok contributes to the target group's fashion consumption. To answer these questions, we will use a quantitative survey which will then be analyzed with a
Buildings worldwide account for 30% of energy consumption and Heating, Ventilation and Air Conditioning (HVAC) represent roughly 38% of a building’s consumption. Therefore, energy savings are crucial for sustainability. The complexity of buildings, with diverse physical domains and large-scale components, presents challenges to achieving energy-efficient operation. Implementing high-performance co
The aim of this thesis was to investigate, develop and implement an Advanced Driver Assistance System (ADAS) feature for an ultra-light electric vehicle, focusing specifically on an Automatic Emergency Brake (AEB). The fundamental requirements, for an ultra-light electric vehicle, were found and investigated through experiments. A person detection algorithm with camera and LiDAR was developed with
