This thesis presents a method, based on feedback linearization, for controlling a general 3-degree-of-freedom simulation model of an aircraft. Only aircraft models that utilize Taylor approximations of the aerodynamic coefficients are considered. The intent is to be able to simulate the same mission with different aircraft models without having to tune the control system specifically for each mode
The decline of bees, such as bumblebees, over the last decades raises concerns as they are key pollinators in both agricultural and natural ecosystems. One proposed cause for the decline of wild bees is competition for food resources with managed honeybees. Detrimental effects of competition can result where co-existing species exhibit a high degree of shared resource use (i.e., niche overlap). Th
Weather extremes, such as extreme heat and precipitation, are expected to increase in both intensity and duration due to climate change. Previous research suggests members of the acute homeless population are particularly vulnerable to such climatic extreme events. However, this has not been studied earlier in the context of Sweden. In this thesis, I merge the two persistent global problems, weath
På grund av energiomställningen, Sveriges mål om att ha en fossilfri elproduktion 2040 samt målet om nettonollutsläpp av växthusgaser 2045 förväntas en omfattande utbyggnad av förnybara energikällor ske. I denna rapport har därför elbehovet, potentialen för elproduktion, möjliga framtida systemproblem samt lösningar undersökts. Efter en omfattande litteraturstudie har det framkommit att elbehove
The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. The lignin was then c
In 2021, the Icelandic government stated that Iceland will implement an energy transition plan with the goal of becoming a 100% carbon neutral and fossil free nation by 2040, furthermore, that a doubling in renewable energy production was needed to reach that goal. This led to an upsurge of a discourse among stakeholders and concerned citizens about the future of Iceland. This thesis is an attempt
The extreme short-term precipitation in Sweden is expected to increase due to climate change. This means that there will be an increased risk of floodings in urban areas. Several cloudbursts during the past decade have caused major damage to communities all over Sweden with high restoration costs as a result. To prevent further damage, solutions for managing increased amounts of water are needed.
In this thesis, I investigate the experience of physical pain. Through an analysis and assessment of the data in the form of qualitative interviews collected for this thesis, the aim has been to show that meaning-making is fundamental to our experience of (physical) pain. At its core, this thesis contends that physical pain can not be reduced to physiological stimuli and that an investigation must
The recent peak in interest for artificial intelligence, partly fueled by language models such as ChatGPT, is pushing the demand for machine learning and data processing in everyday applications, such as self-driving cars, where low latency is crucial and typically achieved through edge computing. The vast amount of data processing required intensifies the existing performance bottleneck of the da
Debt has gained paramount importance for policy makers, stakeholders, and investors due to its far-reaching implications on economic stability, growth prospects, and financial resilience. Meanwhile, environmental conditions are increasing in importance when assessing credit risk. This study examines the relationship between environmental risk, environmental progress, and credit default swap (CDS)
Children primarily learn about climate change (CC) through media, including children’s films. Films can influence emotions, shaping perceptions and actions regarding CC. However, research focusing on media narratives consumed by children is lacking, leaving a significant knowledge gap. To bridge this gap, this study employed narrative analysis, examining CC depictions in six children's animate
With fossil fuel-dependencies affecting energy generation, and renewables being contextually limited by intermittency and dispatchability issues, this work explores European Pressurized-water Reactors (EPRs) as a nuclear-based climate mitigation measure in France and in the EU. Through its conceptual framework, this paper evaluates the technical potential of EPRs through the gate-keeping effect of
Denna studie undersöker hur e-handelsföretag har upplevt och påverkats av inflation vilka marknadsföringsstrategier de använder samt hur de har arbetat med värdesamskapande under inflationen mellan åren 2020 till 2023. Studien fokuserar på inflationstider men bidrar till forskningen om kriser. Studien har värdesamkapande, agil marknadsföring, integrerad marknadskommunikation och varumärkeskännedom
Examensarbetet Mellan samhälle och natur undersöker arkitekturens möjlighet att tillgängliggöra natur och rekreation. Studien tar avstamp i den svenska friluftslivstraditionen, dess historia och utveckling samt i rurala platsers möjligheter och utmaningar. Hur kan fler människor välkomnas i naturen och kan ett gestaltat tillägg i denna miljö tillgodose olika behov och brukargrupper? Hur kan ett ru
Problemet som studien ska undersöka är hur krav och tilldelningskriterium kopplade till klimat och miljö används och värderas i offentlig upphandling av. De primära frågorna som studien avser att besvara är följande: Vilka krav och tilldelningskriterium ställs idag kopplat till miljö och klimat vid offentlig upphandling av byggprojekt? Hur utvärderas och formuleras krav och tilldelningskriterium k
The HUSH-MORC2 corepressor has emerged as a key player in epigenetic silencing of L1 retrotransposons and other mobile genetic elements during human development. In the ‘canonical’ mode of its recruitment to chromatin, HUSH makes interactions with nascent transcripts from target elements, leading to the assembly of SETDB1, which deposits the repressive heterochromatin mark H3K9me3, and chromatin r
Amidst a climate and biodiversity crisis, transitioning from fossil fuels to renewable energy sources has become imperative. On the Åland Islands, planned large-scale offshore wind farms offer potential economic growth but entail environmental and social impacts. This study investigates the discourses of renewable energy transitions on Åland using a political ecology framework for energy transitio
Worldwide, Indigenous peoples have played a critical role in preserving ecosystems and biodiversity. Historically oppressed by colonial institutions, they are today confronted with detrimental effects of the global food system and increasingly pronounced changes in climate that jeopardise their ability to produce food. In reaction to globalisation, food sovereignty advocates the right of peoples t
