This study investigates continuance intention to use Duolingo from a post-adoption perspective, drawing primarily on the Expectation-Confirmation Model (Bhattacherjee, 2001). In gamified mobile language learning, value is not achieved through initial adoption alone, but through repeated use that supports meaningful learning progress. Therefore, this study examines why active users intend to contin
Recommender agents providing personalised recommendations for customers on online webstores or video streaming platforms have gained a lot of attention recently with the advancement of Artificial Intelligence improving their accuracy and efficiency. However, due to the black box nature of machine learning, sometimes it is difficult for consumers to understand why a certain set of items are recomme
This thesis develops a locally deployed LLM-assisted system for automating CFD simulations from natural-language physical modelling tasks, including OpenFOAM case setup generation, solver execution, error diagnosis, and iterative correction. Unlike many recent LLM-driven CFD agents that mainly rely on frontier cloud models, this work investigates whether open-weight local LLMs with stronger data p
This thesis explores how consumers interpret and emotionally respond to AI-driven changes in the communication of iconic brands. As artificial intelligence becomes increasingly integrated into marketing and brand communication, it raises questions about how such changes affect consumers’ perceptions of authenticity, trust, and emotional connection. Through a qualitative study, the research examine
Stora delar av det svenska bostadsbeståndet kännetecknas av nyttomaximering och konformitet. Examensarbetet undersöker några av Sveriges mest unika bostadshus, nämligen vattentorn som ombildats till bostäder. Författaren intresserades av ämnet på grund av ett uppmärksammat bostadsvattentornsprojekt i sin hemstad och kopplar fenomenet till två vanligen förekommande begrepp i civilingenjörsutbildninWith time buildings are prone to lose their purpose. Meanwhile cities face demand for urban densification. This paper focuses on obsolete water towers repurposed to unique housing in Sweden. In Sweden 15 water towers have been turned into multy-family dwellings. This has resulted in 266 flats of which 156 are reserved for students. The total floor area of these are 12 761 square meters.

Användningen av generativa AI-verktyg ökar snabbt inom offentlig sektor och erbjuder betydande effektiviseringsmöjligheter, men ställer samtidigt nya krav på informationssäkerhet. Denna studie undersöker hur anställda inom svensk offentlig sektor uppfattar och hanterar informationssäkerhetsrisker vid användning av generativa AI-verktyg, samt vilken roll policy och riktlinjer spelar i detta. Studie
Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal interstitial lung disease driven by persistent fibroblast activation, abnormal epithelial to mesenchymal signaling and excessive extracellular matrix (ECM) remodeling. Better pre-clinical models are needed to reproduce these processes and to support antifibrotic drug development. This thesis tested whether an in vitro co-culture model
Examensarbetet undersöker hur järnvägen idag dräneras och hur klimatförändringar påverkan järnvägen och dess dräneringssystem. Resultaten visar att vatten har en stor påverkan på järnvägens hållfasthet och hur viktiga trummor är för att hantera vattenflöden. I och med klimatets förändringar som orsakar större nederbördsmängder och vattenflöden i norra Sverige och torka i södra kommer framtidens prThe thesis evaluates how the railway is drained today and how climate change will affect the railway and its drainage capability. The results show that water has a big impact of the railways structural integrity and how important drums are to handle waterflow. The climate change causes greater precipitation amounts and waterflows in northerns Sweden and droughts in the south. The project planning
Brookfield viscometers are widely used in industrial quality control because they are simple and practical, but the viscosity values obtained are relative to the instrument, spindle, container geometry, and measurement procedure. In contrast, rotational rheometers such as the Anton Paar RheolabQC provide more defined rheological data under controlled shear conditions. This thesis developed and eva
Modern integrated circuits contain extensive on-chip instrumentation—Ring Oscillators (ROs), temperature sensors, voltage monitors, and delay-measurement circuits—originally intended for reliability monitoring and process calibration. The same physical sensitivity that makes these instruments effective sensors also makes them potential side-channel receivers. An adversary who can place or exploit
The loss of regulatory control over radioactive material and sources poses great risks to public safety. Such a situation necessitates the development of protocols and methods for effective and accurate localisation, characterisation and securement of the materials. Mobile gamma spectrometry, particularly using vehicle-borne detectors, has emerged as a viable method for in-situ characterisation of
Förarapplikationer används i allt större utsträckning hos yrkesförare för att stödja företags ruttplanering, orderhantering, dokumentation och intern/extern kommunikation. När förare behöver läsa, tolka och/eller interagera med information i situationer kopplade till körning kan dessa system även skapa visuell, manuell och kognitiv distraktion, vilket ökar risken för trafikrelaterade skador. DettaDriver applications are increasingly used in professional driving to support route planning, order management, documentation, and communication. When drivers need to read, interpret, or interact with information in close proximity to driving, these systems can also create visual, manual, and cognitive distractions, increasing traffic safety risk. This master's thesis was conducted in collabora
This thesis examines Flatus lifir, a widely recognized phenomenon in Iceland’s rural public space. Located in Kollafjörður on the outskirts of Reykjavík, the work has existed in several different forms over time and has become embedded within Icelandic public memory and popular culture. It appeared as an anonymous graffiti tag decades ago and later evolved into three distinct mural iterations in t
In estuarine ports, ballast water operations can be affected by short-term changes in water quality, especially when suspended sediment concentrations increase. This thesis assesses turbidity-related water-quality conditions relevant to ballast water operations in the Port of Hamburg, focusing on Seemannshöft during 2018–2024. Because direct total suspended solids (TSS) measurements were limited,
Background: Monitoring of essential physiological parameters is standard practice during magnetic resonance imaging, MRI. However, signal extraction and post-examination analysis of these parameters at SUS Lund is limited, mainly due to insufficient software capabilities. Yet researchers and physicians alike have voiced their interest in a program that manages structured and synchronized capture o
Natural products are of great interest for a variety of powerful applications that are related to the biological activity of small organic molecules inspired by nature. While the landscape of natural products is structurally abundant, their occurrence in nature is very scarce, posing a challenge to isolate them in quantities required to be studied and used in pharmaceutical application. This work
Svensk hälso- och sjukvård präglas av personalbrist, hög arbetsbelastning och svårigheter att behålla sjuksköterskor. Trots att fler utbildar sig till sjuksköterskor lämnar många yrket eller söker sig till andra arbetsgivare på grund av bristande arbetsmiljö och hög psykosocial belastning. Detta påverkar vårdens kvalitet, kompetensförsörjning och arbetsmiljö. Det finns av den anledningen behov
Russia’s full-scale invasion of Ukraine in February 2022 produced one of the largest displacement movements in contemporary Europe, with millions of Ukrainians seeking protection across the European Union. While migration from Ukraine has often been understood through the lenses of safety, protection, and humanitarian need, wartime mobility can also become morally charged. Decisions to leave, stay
Wildfire observations are increasingly important as changing wildfire regimes globally affect societies and ecosystems. Wildfire behaviour, comprising the way that wildfires spread through the landscape, connects wildfire to its physical controls and has been shown to predict other wildfire characteristics. However, observations of wildfire behaviour are limited due to the spatial and temporal res
