This thesis investigated the potential of using reactive power compensation to solve overvoltage issues caused by high amounts of distributed generation, such as rooftop photovoltaic (PV) systems, in the low voltage grid. High voltages are caused by increasing distributed generation as the Swedish power grid shifts from centralised to decentralised power production. The aim was to manage overvol
Using data on Mergers and Acquisitions (M&A) transactions available on the S&P Capital IQ database, this paper aims to contribute to the growing body of knowledge on Emerging Market Multinational Enterprises (EMNEs). Basing itself on the idea that EMNEs may differ significantly in their behavior, investment patterns, and strategic choices from their counterparts from already established ma
This study investigates why certain Swedish companies voluntarily choose to implement the Corporate Sustainability Reporting Directive (CSRD) before it becomes a formal requirement. Through qualitative interviews with sustainability managers, the thesis explores how companies strategically justify their decisions and how they interpret and adapt to the new regulatory framework. The analysis is bas
Betsockerprocessen är en energiintensiv process där ångdriven indunstning används för att avlägsna stora mängder vatten från den upprenade tunnsaften, som innehåller det från betorna extraherade sockret. I takt med industrins önskade fokus på energieffektivisering har membranteknologier för förkoncentrering av tunnsaften fått ett ökat intresse. Trots lovande resultat i ett begränsat antal försök åThe beet sugar process is an energy intensive process relying on steam evaporation to remove large amounts of water from the purified thin juice containing the sugar extracted from the beets. As the industry seeks greater energy efficiency, membrane technology for pre-concentration of thin juice has attracted interest. Limited trials have shown promise but fouling, sugar losses or high osmotic pre
Drönare och andra eldrivna luftfordon gör allt större inslag i dagens samhälle, med unik potential att forma framtiden. För en effektivare drift kan kontraroterande propellerpar användas. Interaktionen mellan propellrarna är däremot komplex, men här visas det tack vare optimering att en verkningsgrad högre än för två separata propellrar kan uppnås – du kan båda äta kakan, ha den kvar och få en smuContra rotating propellers (CRP) exhibit several benefits compared to a traditional single-propeller setup. It has for example a high thrust-to-area ratio and offsetting torque is minimized. Accordingly it has several applications, one of them being electrical vertical take-off and landing (eVTOL) aircraft. The present thesis sets out to optimize the contra rotating propeller setup, both from a mo

This thesis presents a simulation-driven methodology for evaluating float design in aseptic filling machines, with the objective of reducing surface instabilities and air entrainment that contribute to splashing during the filling of viscous food products. The study was conducted in collaboration with Tetra Pak and focuses on understanding how float geometry, particularly mass and radius, affects
This thesis investigates the relationship between board composition and internationalisation in large U.S. consumer discretionary firms, using the foreign asset ratio as a measure of global engagement. Drawing on resource dependence, agency, contingency, and upper echelons theory, it explores the effects of board size, average age, tenure, and gender diversity and assesses how Porter’s Generic Str
The current agricultural model is criticized for its imperialist character and focus on productivity, and it affects peasants and small-scale farmers. However, the United Nations Declaration on the Rights of Peasants and Other People Working in Rural Areas (UNDROP), adopted in 2018, could have an impact. The question in focus is: What contribution can the UNDROP, as a soft law instrument, make to
Mer än 150 miljoner ton plast. Detta är den mängd som just nu befinner sig i våra hav, och denna siffra stiger varje dag. Detta har destruktiva konsekvenser för de djur som lever där. Djuren fastnar i plasten och kan skadas både in- och utvändigt. Men plasten är lömskare än så. För att i plasten gömmer sig kemikalier som kallas för bisfenoler. Denna studie utvärderar vilka konsekvenser dessa har pThis study systematically reviews the endocrine-disrupting effects of Bisphenol A (BPA) and Bisphenol S (BPS) on aquatic vertebrates and invertebrates to assess potential health- and ecological risks. Scientific articles were analyzed to compare the impacts of these chemicals on reproductive systems, oxidative stress, neurotoxicity, and metabolism. Results indicate that BPA, even at low concentrat
Quantum entanglement is a fundamental resource for various quantum information applications including quantum computing, cryptography, and teleportation. However, detecting entanglement in practice can be challenging due to noisy measurements and limited control over the systems being studied. Steering, which is a distinct nonlocal property between entanglement and bell nonlocality (the strongest
The immune cell population is essential for understanding the immune system’s reaction against the tumor. This study identified T cells and myeloid cells in human papillomavirus positive and negative tonsillar cancer biopsies via extracellular markers to investigate the biopsies’ composition, cellular neighborhood, and interactions. A detection method for tertiary lymphoid structure was developed.
This thesis explores the possibilities of integrating semantic transport information in the context of 3D-city modelling by implementing transport surfaces according to standards defined by the 3CIM specification, an extension of CityGML. This approach aims to automatically generate transport surfaces in LOD1 and LOD2, based on the Stockholm city basemap in combination with road geometries that re
This thesis was conducted to explore the capacity of West Slavic culture’s influence on that of early medieval Denmark from the 9-12th centuries through the examination of artifacts from both camps. Through the methodological observation of Danish and West Slavic material culture, their contexts and their connectivity between West Slavs and Danes, I apply assemblage and actor network theory (ANT)

Lake ecosystems are increasingly affected by climate change, leading to prolonged periods of elevated water temperatures. This warming reduces surface water density, intensifying thermal stratification and trapping cold water in deeper layers. Consequently, cold-water fish and other organisms are confined to limited deep-water habitats. Understanding lake thermal structure is crucial for effective
