Semantic search using large language models (LLMs) combined with an approximate nearest neighbor (ANN) index is the current state of the art in search technology. Semantic search aims to match a user’s search query based on its contextual meaning and intent with a highly relevant search result, rather than relying solely on matching keywords. While semantic search is superior to keyword-based sear

In robotic systems, uncertainty in model parameters, such as joint stiffness, link lengths, or mass distributions, can significantly affect performance and precision. This thesis investigates the quantification and propagation of such uncertainties using the programming language Julia, with a focus on developing a systematic framework for uncertainty-aware modeling and simulation. It leverages the

With the rapid diffusion of short video social media, a wave of rural influencers has emerged on China’s TikTok (Douyin), using short-form content to build personal brands and engage in sociocultural expression. Anchored in practice theory (Shove et al., 2012), this study adopts the “material–competence–meaning” triadic model to examine how these rural creators strategically construct personal bra

Hållbarhet och cirkulärt byggande blir alltmer centrala i Sveriges miljömål, men implementeringen av Design för Demontering (DfD) är fortfarande begränsad. Denna studie undersöker de ekonomiska, regulatoriska och tekniska hinder som försvårar en storskalig tillämpning av DfD i den svenska byggsektorn samt identifierar strategier för att påskynda dess genomförande. Studien bygger på kvalitativ

This thesis investigates how managers in retail-focused small and medium-sized enterprises (SMEs) navigate the complexities of internationalisation. While globalisation and digitalisation have increased accessibility to foreign markets, SMEs face persistent challenges including limited internal resources, unfamiliar institutional environments, and market uncertainty driven by consumer behaviour. O

Energiomställningen utmanar elnätets förmåga att leverera den mängd effekt som efterfrågas. I detta arbete undersöks potentialen för effektstyrning i nätet som en möjlig lösning på denna utmaning. Den pågående elektrifieringen är avgörande för att Sverige ska nå sina klimatmål men innebär samtidigt en utmaning för nätägare. Elbehovet ökar snabbt samtidigt som det sker en övergång till fossilfria The aim of this master's thesis is to investigate the potential of active power flow control to mitigate bottlenecks through the implementation of phase-shifting transformers (PST) and static synchronous series compensators (SSSC). The report is based on a case study of E.ON's sub-transmission network in the southern part of Sweden, where these components are introduced to mitigate future

This thesis analyzes Brazilian students’ psychological barriers to accessing international education opportunities. Based on a mixed-methods approach, it explores how internalized feelings of inferiority, low academic confidence, and perception of not belonging are rooted in colonial legacy, at a racial and gendered intersection, more strongly perceived by marginalized groups. The study emphasizes

2024 godkände Lunds kommun en ny strategi för utveckling av Lunds stadskärna. I strategin läggs ett anmärkningsvärt förslag fram: att ta bort de vanliga stadsbussarna från stadskärnan, och ersätta dem med lokala minibussar. Små stadskärnebussar är i sig inget nytt koncept, men fungerar vanligen som ett komplement till den ordinarie kollektivtrafiken; inte som en ersättning. Studier av jämförbara lIn 2024, Lund municipality approved a new strategic document about enhancing the city centre of Lund. In this document, a questionable suggestion is put forth: to replace the buses serving the city centre with minibuses. City centre minibuses is not an entirely new concept; however, it is conventionally used as a complement to ordinary buses rather than as a replacement. Studies on similar measure

Automated servo systems are widely used in today’s industry. Therefore, there is high value in improving the reliability and accuracy of these systems and reducing costs. One way to achieve this is to remove the gearbox component, since it typically represents a large fraction of the system’s cost, and it contains many moving parts which will wear and eventually fail. However, removing the gearbox

What happens when open, informal spaces disappear – and specifically, what happens when these spaces disappear in a city that used to be full of them? My project is rooted in two things. The first is the highly debated ”Amazon Tower” in Friedrichshain, and the polarized urban conditions around it. The second is my love for Berlin. Berlin has always been a city in flux. However, the latest round

Purpose: The purpose of this study is to explore how consumers perceive brand-centric entertainment films, as well as how these films influence associations with the brands featured within them. Specifically, the study seeks to identify if and how these films shape or reshape brand meaning from a consumer perspective. Methodology: The study takes a qualitative approach and employs a research desi

This thesis presents a topology optimization framework for anisotropic elastoplastic structures based on the deformation theory of plasticity. Traditional methods often assume linear elasticity and isotropic material behavior, which limits their ability to model real-world materials that exhibit anisotropy and undergo plastic deformation. Although incremental elastoplastic models can accurately ca

Sudan har sedan april 2023 präglats av ett brutalt inbördeskrig mellan Sudanese Armed Forces (SAF) och Rapid Support Forces (RSF), vilket resulterat i en statlig kollaps och omfattande civil fördrivning. I detta sammanhang har konfliktrelaterat sexuellt våld (CRSV) blivit särskilt framträdande. Denna uppsats analyserar hur CRSV konstrueras i tre centrala internationella rapporter från FN:s högkommSince April 2023, Sudan has been engulfed in a brutal civil war between the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF). The conflict has triggered the collapse of state institutions and forced the displacement of millions. Amid this humanitarian crisis, conflict-related sexual violence (CRSV) has emerged as a defining and deeply troubling feature. This thesis explores how CRSV

Denna studie undersöker hur business controllers uppfattar förändringar i sin yrkesroll i samband med att generativ AI (GenAI) införs i ekonomistyrningen. Syftet är att förstå hur arbetsuppgifter, professionell identitet, attityder till tekniken samt emotionella och organisatoriska förutsättningar påverkas av denna teknologiska omställning. Studien utgår från rollteori, Technology Acceptance Model

Klimatförändringen är en av vår tids stora ödesfrågor med globala mål satta om att minska utsläppen av växthusgaser. Vårt samhälle är idag byggt runt fossila bränslen och transportsektorn är inget undantag. Medan det på personbilsidan skett en utveckling där elbilar idag utgör en växande del av personbilsflottan så har utvecklingen varit trögare för tyngre kommersiella fordon som lastbilar. En av The transport system of the future needs to be separated from the use of fossil fuels and when it comes to freight trucks, the transition to an electric vehicle fleet appears as the main option. This thesis presents a model that estimates the demand of charging infrastructure of truck fleets based on real-world driving patterns. The model builds on the open-source Multi-Agent Transport Simulation

A rapid increase in renewable energy in response to climate change often generates local conflicts. To achieve a just transition to renewable energy, it is crucial to embed justice into its development processes. I examined the case of solar development in Kushiro, Japan. By combining the theories of multispecies justice and procedural justice, this thesis analyzed how local stakeholders perceive

Chiral C3-symmetric molecules are an important class of compounds with applications in asymmetric catalysis and drug discovery. Few synthetic methods exist to synthesize this class of molecules in a step-economic and concise manner. This work explores a range of chemical transformations to functionalize the D3-symmetric (a,e,i)tribenzo(5,6,11,12,17,18) hexadehydro[12]annulene into C3-symmetric pla

Sifting through complex software logs for the root cause of errors can be a daunting and time-consuming task. This thesis explores a novel approach using knowledge graphs and GraphRAG to empower Large Language Models (LLMs) for more efficient and accurate analysis. The methodology involves utilizing log template mining and a CMake-generated file dependency tree to build the knowledge graph, which
