This thesis presents the development and validation of an analysis framework to study quantum decoherence in neutral B-meson pairs produced at the $\Upsilon(5S)$ resonance, using Monte Carlo simulated data from the Belle experiment. Unlike the $\Upsilon(4S)$, the $\Upsilon(5S)$ provides access to both antisymmetric ($C=-1$) and symmetric ($C=+1$) quantum states through the channels $B^0\bar{B}^0$,
This work studies the mechanism behind the photo-degradation of 2 types of COF nanoparticle, hoping to provide a deeper understanding of photophysics of catalytic process. As a new field of organic materials, COFs are undergoing fast development, which offers a powerful molecular platform for complex structural design and tailorable development. Lots of studies have been carried out to figure out
Malta’s construction boom has resulted an increase in urban density and a decrease in green spaces over recent years. To combat this, in 2025 the social movement Post Għalina launched a campaign to transform Manoel Island, a largely undeveloped island near Valletta, into a national park. This thesis employs a qualitative case study utilizing social movement theory to examine Post Għalina’s creatio
Sweden’s housing policies from the post-Second World War to the 1970s were grounded in the idea of sanering, slum-clearing and reconstruction, and essentially aimed at reforming regional planning. Through the sanering approaches, some regions changed their characteristics in a shrinking way. Nevertheless, previous studies rarely focused on either sanering or its impacts on regional development. Mo
Rysslands fullskaliga invasion av Ukraina har inneburit en avgörande förändring i svensksäkerhetspolitik. Inom totalförsvaret har kommunerna en central funktion genom sitt ansvar församhällsviktig verksamhet och för den civila beredskapen. Denna studie syftar till att undersöka omoch hur kommunal planering för civil beredskap har förändrats till följd av det nya säkerhetspolitiskaläget. FrågeställThis study aims to examine if and how the planning of civil preparedness in Swedish municipalities haschanged in response to a shifting global security landscape. The study uses the year 2022 as a breakingpoint. This is due to Russia’s full-scale invasion of Ukraine and its impact on European securitypolitics. Using Thierry Balzacq’s understanding of securitization and Michel Foucault’sgovernmenta
The UK achieved the ambitious goal of becoming the first G7 country to phase out coal-firedelectricity, with its last power station, Ratcliffe-on-Soar closing in 2024. Ensuring thisgeneration of transitioning communities does not follow in the footsteps of ‘left behind’ UKex-mining villages for example, is imperative. This study investigates and compares theimaginaries of place leaders and locals
Due to climate change, cocoa harvests have decreased yearly, leading to increased scarcity and rising market prices of cocoa butter. At the same time, cocoa butter is a key ingredient in chocolate, responsible for its unique melting properties. Thus, there is a growing interest in producing fats with similar characteristics, so called cocoa butter equivalents. Cocoa butter equivalents consist of s
Inspired by the experimental work performed in the research group led by Ville Maisi at Lund University, this thesis investigates a hybrid quantum setup in circuit quantum electrodynamics (cQED). The system consists of a microwave resonator coupled to a double quantum dot (DQD) acting as an internal sensor to indirectly detect the state of an external quantum system. Using input-output theory and
The rapid public adoption of large language models (LLMs) has transformed written communication and creative production, while simultaneously creating growing concerns regarding authenticity, misinformation, and the preservation of human authorship. As AI-generated literary content becomes increasingly sophisticated, the ability to reliably distinguish machine-generated prose from authentic human
The IPCC’s Illustrative Mitigation Pathways achieving below 2°C of global warming increasingly rely on Direct Air Capture and Storage (DACCS). Research has largely concentrated on techno-economic aspects, while community perspectives have been almost exclusively focused on in the Global North. This thesis presents the first empirical case study of a commercial DACCS facility in Africa. Drawing on
Introduction: Urocanate reductases (UrdA) are enzymes in the gut microbiota that catalyse the production of imidazole propionate (ImP), which is implicated in diseases like type 2 diabetes, and therefore it is of medical interest to co-crystallize the protein with new potential ligands in order to develop inhibitors, which can be used to lower the ImP concentration in the blood. Background: Sever
Denna studie undersöker vilka motiv Lunds kommun framhåller bakom beslutet att anlägga spårvägen i Lund samt hur spårvägen framställs i relation till hållbar stadsutveckling och utvecklingen av stadsdelen Brunnshög. Syftet är att se hur planering av storskaliga infrastrukturprojekt kan ses som en bidragande faktor till attraktionskraft och identitet samt ur ett tillgänglighets- och rättviseperspekThis study examines the motives put forward by the Municipality of Lund behind the decision to construct the tramway in Lund. Framed in relation to sustainable urban development and the emergence of the Brunnshög district, the purpose of this project is to understand how the planning of large-scale infrastructure projects can be analyzed through perspectives of accessibility and justice, as well a
Denna studie syftar till att förstå vilken inverkan gentrifiering kan ha på tillgången till det offentliga rummet, och till att förstå om tillgängligheten skiljer sig mellan socioekonomiska grupper eller stadier av gentrifiering. Studien fokuserar på Vesterbro, Köpenhamn, och utgår från tre offentliga rum. Platserna Maria Kirkeplads, Halmtorvet och Flæsketorvet studerades med hjälp av observationeThis study aims to understand the impact gentrification might have on the access to public space, and to understand if it differs between socioeconomic groups or stages of gentrification. The study focuses on Vesterbro, Copenhagen, where three public spaces were chosen for the research. Maria Kirkeplads, Halmtorvet and Flæsketorvet, were studied through observations, document analysis and mapping.
This study examines how the City Library in Lund functions as a form of social infrastructure and crucial urban public space. This is realized by way of a triangulation approach through the examination of two municipal documents which dictate the programming of the library, an interview with a seasoned librarian, and several semi-structured observations at the site itself. The study is grounded bo
This thesis studies first-order phase-transition dynamics and the associated stochastic gravitational-wave background in classically conformal B − L-like extensions of the Standard Model. The scalar and gauge sectors are formulated at tree level and at one-loop order using a modified on-shell renormalization prescription designed to keep the vacuum structure fixed while allowing the tree-level fla
Modern cloud-based machine learning (ML) services raise significant privacy concerns, as users must share potentially sensitive data with service providers. Private Decision Tree Evaluation (PDTE) addresses this by allowing encrypted queries to be evaluated against a model without revealing either party’s data, typically using Homomorphic Encryption (HE). While existing HE-based frameworks have de
This study presents the development and validation of a new, compact architecture for ultrafast videography using the Frequency Recognition Algorithm for Multiple Exposure (FRAME). Traditional FRAME-systems often have high mechanical complexity, long optical path lengths, and are limited to one-dimensional (1D) informational extraction of refractive index gradients when using Schlieren imaging. Th
Environmental monitoring of Carbon-14 around nuclear power plants (NPPs) has traditionally prioritized gaseous emissions, leaving waterborne liquid discharges unmonitored due to low nominal volumes (<0.5%) and analytical challenges using traditional techniques. However, liquid releases do not experience as effective dilution as gas releases, instead discharging directly into coastal ecosystems whe
