This research assesses the relationship between rainfall spatial distribution and levee failure risks by scouring at the confluence of the Chikugo River mainstream and Kusu River. Using d4PDF large climate ensembles (10,140 years of data), the study integrated a Rainfall-Runoff-Inundation (RRI) model with iRIC Nays 2DH for 2D hydro-morphodynamic analysis.The ensembles were categorized into three g
It is apparent that climate change is progressing, increasing the frequency of heavy rainfall events. In coastal areas, halocline formation caused by increased freshwater inflow can inhibit vertical mixing, reducing oxygen concentration in the bottom layer. The Ariake Sea, an inner bay in Japan with a large tidal range, has faced serious issues such as red tides and hypoxia. Previous studies
Medical image segmentation often relies either on traditional image processing methods, which can be limited in their ability to handle complex image characteristics, or on deep learning approaches, which require large amounts of high-quality annotated data. Hybrid methods that combine these two paradigms offer a potential way to reduce annotation requirements while maintaining strong segmentation
On the 28th of October 2025, Category 5 Hurricane Melissa made landfall in Jamaica. This thesis examines how it was experienced, narrated, and acted upon in Accompong, a sovereign Indigenous Maroon polity in Cockpit Country. Based on six weeks of ethnographic fieldwork (14 November–23 December 2025), we follow Melissa as an unfolding process rather than a bounded event. Guided by political ecology
Accurate calibration is essential for reliable polarimetric measurements in frequency-domain terahertz ellipsometry. In this thesis, we investigate how different sets of calibration samples influence the quality of the extracted 4×4 Mueller matrix in an in-house built terahertz Mueller Matrix Ellipsometer operating in the 170-250 GHz range. Three calibration sets composed of various combinations o
This thesis examines the practices and importance of the “care-tree” (vårdträd) for human-nature relations in Sweden during the 19th and early 20th centuries. The “care-tree” have a long history of use, are entwined with supernatural beliefs, and are said to reflect the well-being and luckiness of the yard where it’s planted. Using theories of social control, non-human agencies and the dwelling pe
The growing accumulation and mismanagement of waste disrupt the ecological systems that sustain human existence, leaving environmental burdens for future generations. This situation highlights the need for circular approaches such as zero-waste management, where waste is treated as a resource rather than discarded. Studying social waste relations in Sweden is particularly relevant, given the count
Malaria is one of the most widespread and life-threatening infectious diseases in the world and is caused by parasites from the genus Plasmodium, transmitted to humans through mosquito bites. Despite great progress in the development of antimalarial drugs, the growing resistance to them, especially chloroquine, is a major problem. New drugs therefore need to be developed and chloroquine analogues
This thesis investigates how urban street design can be reimagined to increase livable public space and improve residents’ perceptions of safety in dense urban neighborhoods. Focusing on the districts of Högaborg, Eneborg, and Söder in Helsingborg, Sweden, the study examines how streetscape design interventions can address persistent negative perceptions of these areas, which residents often regar
European strategic autonomy has been a fluctuating discussion since the end of the Second World War. It has primarily been the project of France, but has mostly failed to materialise. This is partly due to other European states’ worry that such a project would become an extension of French national interests. Some of the strongest opponents of an exclusive European defence cooperation have been sm
This case examines Meta’s strategic response to the 2026 social media addiction trial, where the company faces accusations that Social media design contributes to compulsive use among young users. While competitors such as TikTok and Snapchat chose to settle before trial, Meta decided to defend its practices in court. The case invites students to analyze this decision from a corporate brand and cr
Quantitative studies show that the proportion of young people in Sweden who distrust democracy has increased, mainly among boys. This qualitative interview study, based on qualitative text analysis, seeks an in-depth understanding of young people's experiences of democracy through semi-structured interviews, illuminated by the theory of participatory democracy. The study includes group intervi
It has been close to 40 years since the Chernobyl accident and the introduction of ‘safety culture’, but still there is no consensus on its meaning. This thesis aims at exploring what meanings the Swedish nuclear industry has created out of ‘safety culture’ by situating the construct both contemporarily and historically, using a methodology inspired by phenomenology. The results show that the Swed
Den svenska hälso- och sjukvården återkommer i debatten som både högkvalitativ och samtidigt problemtyngd. Två problem inleder ofta debatten: långa väntetider, återkommande brist på vårdplatser, samt svårigheter att bemanna framförallt primärvården. Den här uppsatsen är strukturerad som en analys kring lösningsalternativet centraliserad styrning. Som utgångspunkt jämför vi därför Moderaternas och
Previous research suggests that freedom of speech has become an increasingly debated concept in contemporary politics, particularly within the rise of populist discourse. This thesis asks how left and right populist actors in the United States invoke “free speech” rhetoric in response to cases of political violence, and whether these patterns can be understood as weaponization of free speech. The
Trust-Based Governance and Leadership (TBGL) has been proposed as an alternative to New Public Management (NPM) to mitigate its negative effects on working conditions, service quality, and professional autonomy in public administration. This thesis examines a Swedish municipality seeking to become a national forerunner in TBGL. Based on an interview study, it analyses a municipal initiative aimed
Bekämpningen av penningtvätt utgör ett centralt samhällsintresse inom Europeiska unionen och har gett upphov till ett omfattande regelverk som ställer långtgående krav på att verksamhetsutövare behandlar och lagrar personuppgifter. Samtidigt har skyddet för den personliga integriteten stärkts genom EU:s allmänna dataskyddsförordning (GDPR). Regelverken är inte direkt motstridiga, men förutsätter eThe fight against money laundering constitutes a central public interest within the European Union and has resulted in an extensive regulatory framework imposing far-reaching obligations on obliged entities to process and retain personal data. At the same time, the protection of personal privacy has been strengthened through the EU General Data Protection Regulation (GDPR). Although these regulato
