This thesis investigates the economic and operational consequences of price-responsive operation of a large-scale alkaline electrolyzer producing hydrogen for fossil-free steel production. A time-resolved linear optimization model was implemented in Python, describing the interaction between a 740 MW electrolyzer (37 units of 20 MW), a hydrogen storage and a constant hydrogen demand. Three operati
The revised Energy Performance of Buildings Directive (EPBD) strengthens the regulatory framework for improving the energy performance of the existing building stock in the European Union. In Sweden, the implementation of the directive is particularly relevant for residential buildings with low energy performance, especially buildings in energy classes F and G. This thesis examines how the revised

Debt-for-nature swaps have been designed to address the polycrisis of high debt, climate change and biodiversity loss in developing countries by restructuring sovereign debt and directing resultant savings towards conservation. However, they are marred by multiple drawbacks including the violation of debtor nation sovereignty by international financial actors. This thesis attempts the first academ
This thesis explores the regulatory friction that surfaces when the General Data Protection Regulation (GDPR) and the Artificial Intelligence Act (AI Act) apply side by side to high‑risk AI systems. It homes in on three connected problems. First, there is a procedural overlap between the Data Protection Impact Assessment (DPIA) and the Fundamental Rights Impact Assessment (FRIA). Second, a normati
Denna studie undersöker hur återkoppling används på gymnasiet i individuell instrument- och sångundervisning. Genom stimulated recall observerade vi två lektioner och genomförde sedan intervjuer med alla fyra informanter för att få både lärarnas och elevernas perspektiv. Sedan analyserade vi datan utefter en hermeneutisk ansats. Resultatet visade att olika typer av återkoppling förekom i undervisnThis study investigates how feedback is used in instrument and singing lessons in upper secondary school. We examined teachers' feedback and students' responses through stimulated recall where we observed two lessons and conducted interviews with all four informants to gain both teachers and students perspectives. Afterward we analyzed the data using a hermeneutic approach. The results of
Flygplatsbanor utsätts för stora belastningar från flygplan, vilket skapar ett behov av tillförlitliga metoder för att bedöma beläggningarnas bärighet. Traditionellt har ACN-PCN-systemet använts internationellt, men systemet har begränsningar eftersom det inte tar hänsyn till trafikvolym eller den kumulativa nedbrytningen av beläggningen över tid. För att åtgärda dessa brister introducerade ICAO AAirport pavements are subjected to severe loads from aircrafts, creating a need for reliable methods to evaluate pavement bearing capacity. Traditionally, the ACN-PCN-system has been used internationally, but the system has limitations since it does not consider traffic volume or cumulative pavement deterioration. To address these shortcomings ICAO introduced the ACR-PCR-system. The aim of this th
In recent years, the issue of algorithmic bias in systems has gradually drawn the European Union’s attention to the relationship between data protection and non-discrimination principles. To detect and mitigate bias in high-risk AI systems, developers often need to process special categories of personal data such as information relating to race, gender or health. However, Article 9 of the GDPR pro
This thesis tries to examine distributional spatial equity in accessibility to green infrastructure and essential services across DeSO areas in Malmö municipality, Sweden, in 2022. The study investigates how accessibility varies spatially in relation to public parks, public transport stops, schools, and healthcare facilities, and evaluates whether accessibility advantages and disadvantages are dis
This thesis examines the growing role of algorithmic and data-driven systems in European Union asylum procedures and explores their implications for legal accountability, procedural fairness, and fundamental rights protection. As migration governance increasingly relies on biometric databases, interoperability frameworks, and automated decision-support systems, questions arise regarding the compat
This Thesis presents the design and investigation of high-frequency fundamental VCO(Voltage controlled oscillator) and injection-locked frequency dividers (ILFDs) for millimeter-wave (mmWave) and sub-terahertz (sub-THz) communication systems. A magnetically tuned voltage-controlled oscillator (VCO) and magnetically tuned ILFD pair are proposed for sub-THz applications. The 140 GHz fundamental VCO
This study examines how medical social workers within the Swedish women’s healthcare system approach psychosocial assessments in cases of late abortion applications. The aim was to explore how professional ideals, role perceptions, and practices are shaped within the field of abortion care and how these factors may affect equal access to care.

The tea sector is one of Kenya's most important industries, with a big impact on the country's economy and socio-economic development. At the same time, tea manufacturing is highly energy-intensive and strongly affected by electricity tariffs and high production costs. Due to the favorable weather conditions and growing renewable energy ambitions in Kenya, Solar Photovoltaic (PV) systems p
Key actions, tactical cooperation, and spatial relationships in sports activities are usually recorded through 2D videos, which limits users’ ability to understand the game in three-dimensional space. Although professional sports events can provide Free-Viewpoint Video using large-scale camera arrays, such systems are difficult to deploy in low-cost scenarios such as community games and personal t
Sveriges utveckling i form av ett mer digitaliserat och elektrifierat samhälle medför en högre belastning på elnätet. Samtidigt är elnätet inte dimensionerad för denna belastning. Nätets kapacitet är direkt kopplat till effektuttag och för att jämna ut och minska höga effekttoppar i nätet beslutades det därför att införa effektavgifter senast den 1 januari 2027. Under tiden arbetet skrevs beslutadSweden’s development towards a more digitalized and electrified society is increasing the load on the electricity grid. At the same time, the grid is not dimensioned for this level of demand. The grid capacity is directly linked to power demand, and to reduce and smooth out high-power peaks, it was decided that demand-based electricity tariffs would be introduced no later than January 1, 2027.
