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

Mellan övervuxna spår, väderbitna tegelfasader och tomma hallar undersöker vi i detta examensarbete kraften i postindustriella platser, inte som statiska element från det som varit, utan som en generativ grund för det som kan komma att bli. Vi rör oss i spänningsfältet mellan bevarande och förnyelse, där vårt arbete ifrågasätter dualiteterna gammalt/nytt, produktion/boende och minne/utveckling, vBetween overgrown tracks, weathered brick facades and empty halls, this thesis explores the power of post-industrial sites, not as static elements of the past, but as a generative basis for what might be. We operate in the tension between preservation and regeneration, where our work questions the dualities of old/new, production/living and memory/development, which often characterise discussions

Today, buildings account for approximately 30% of worldwide energy use, with HVAC (Heating, Ventilation, and Air Conditioning) systems representing nearly 40% of that total. Improving the energy efficiency of HVAC systems is therefore essential for reducing operational costs and mitigating environmental impact. Because HVAC systems operate continuously and under strict operational constraints, acc
