The thesis focuses on the design of a laboratory setup for a 100 kW fuel cell system, intended for heavy-duty vehicle applications. The increasing interest in Proton Exchange Membrane (PEM) fuel cells as a viable alternative for long-haul transport stems from the limitations of battery-electric vehicles, particularly due to the weight and energy density constraints of current battery technologies.
Magnetic resonance imaging (MRI) is a medical imaging technique used to generate 3D cross-sections of body parts for medical diagnosis and monitoring. MRI scanners have a resolution that depends on the strength of their magnetic field, measured in Teslas (T). Most clinical scanners have a resolution of 1.5T and 3T resolution is used in wealthy hospitals and for research. A few research centers als
Esta investigación analiza la feria agroecológica UNIMINUTO, un ejemplo destacado de economía solidaria y de consumo sostenible en Bogotá, Colombia. Al utilizar la teoría de las prácticas sociales y entrevistas semi-estructuradas con 10 consumidores frecuentes, este estudio identifica las principales motivaciones de los consumidores para asistir a este espacio, que incluyen el apoyo a los productoThis research examines the UNIMINUTO agroecological fair, a prominent example of solidarity economy and sustainable consumption in Bogotá, Colombia. Employing a social practice theory lens and semi-structured interviews with ten frequent attendees, this study identifies key consumer motivations, including support for local producers, product quality, health benefits, knowledge acquisition, and the
With the acceleration of climate change and biodiversity loss in recent years, the neoliberal economic response to environmental challenges has been to integrate nature into market mechanisms, hoping to account for ecological degradation while funding nature conservation and restoration. This study critically examines the resulting financialisation of conservation, focussing on Scotland in particu
Peru grapples with severe water insecurity due to climate change and ecosystem degradation. In response, the government implemented the Ecosystem Services Compensation Mechanism for Water Security (MERESE), employing Payment for Ecosystem Services to incentivize nature-based solutions. Central to MERESE are Good Governance Platforms, multi-stakeholder bodies overseeing implementation and ensuring
This thesis explores Danish social workers' sensitivity to the risk of committing microaggressions towards nonbinary clients. The theoretical framework primarily relies on microaggression theory. As a point of departure, the author developed a Microaggression Scale for Nonbinary Clients, which includes eight microaggressions that nonbinary clients might experience from social workers. The empi
Continued digitization has seen the banking sector which is positioned as a national critical infrastructure face an ever-growing number of cyber-threats. This, has necessitated the need for proactive measures for detection and prevention, owing to an expanded threat landscape. This thesis proposes an approach centered on leveraging data analysis and Machine Learning (ML) to analyze and predict th
In central Budapest, when the city of Pest was developing, urban policy led to small plots built on all four sides mak- ing up the larger neighborhood block structures. Each small lot was centered around its even smaller courtyard, lead- ing to a myriad of small open spaces with little sunlight or activity. Many of these plots today have fallen into disrepair, becoming parking lots or unused p
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
Solen skiner, det är tidigt på morgonen och det känns redan varmt i staden. En sådan dag är det många som söker svalkan, men vart ska de gå i städerna? Stadsmiljön domineras ofta av bebyggelse, gator och andra hårdgjorda ytor som kan upplevas väldigt varma. Många söker sig till områden i städer där de kan svalka sig och undkomma värmen, vilket blir allt viktigare för invånare i urbana områden och 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

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
