Climate change is expected to increasingly challenge agricultural systems worldwide, and Sweden is no exception. Although agriculture represents a relatively small share of national employment, it plays a critical role in food security, particularly in Skåne County, which contains some of the country’s most productive farmland. This thesis investigates how deviations from long-term average tempera

Stora språkmodeller (LLM) har uppvisat anmärkningsvärda förmågor inom en rad olika uppgifter inom naturlig språkbehandling (NLP). Deras prestanda är dock mycket känslig för den inledande prompt som används för att fråga dem. Manuell promptkonstruktion, även om den är effektiv, är ofta tidskrävande och kräver betydande expertis. Denna avhandling undersöker promptoptimering, med fokus på en automatiLarge Language Models (LLMs) have demonstrated remarkable capabilities across various Natural Language Processing (NLP) tasks. However, their performance is highly sensitive to the input prompt used to query them. Manual prompt engineering, while effective, is often time-consuming and requires significant expertise. This thesis investigates Prompt Optimization, focusing on a closed-loop, automated

This study presents a mineralogical, textural and structural assessment of the Cambrian Faludden Sandstone Member (Borgholm Formation) and Lower Silurian mudstone (unspecified formation), for their potential use as reservoir and caprock, respectively, for deep carbon storage in the Swedish sector of the Baltic Sea subsurface.

There is an expanding literature on the economic long-term effects of exogenous shocks such as armed conflict and economic crises. While some studies find evidence of poverty traps, the majority support the neoclassical prediction of eventual catch-up growth. This study contributes to the debate by examining Cambodia, which arguably became the most severely bombed country in history and site of on

Intangible assets are a cornerstone of the modern technological economy. Intellectual property (IP) provides incentives for continued scientific development through the protection of innovation and creativity. This technological development has allowed vast creations that solve daily challenges; nevertheless, as the negative externalities seen in the effects of anthropogenic climate change become

Vi använder dem varje dag utan att tänka på det. PFAS är kemikalier som finns i regnjackor, stekpannor, matförpackningar och till och med i brandskum. Problemet är att de inte bryts ner i naturen. De sprids i stället med vatten och kan till slut hamna i våra sjöar och i vårt dricksvatten. Och det är precis vad som händer i sjön Bolmen. Bolmen är inte vilken sjö som helst. Den är en av södra SverigPer- and polyfluoroalkyl substances (PFAS) are a group of highly persistent synthetic chemicals that have raised growing concern due to their widespread presence in the environment and potential health effects. This study focuses on Lake Bolmen, one of southern Sweden’s most important sources of drinking water, and investigates how PFAS enter and accumulate in the lake. A total of 23 PFAS compound

The research analyzes the narratives of LGBTQ+ people who are in exile from Russia and examines how their experiences reflect broader security narratives within Russian politics. To carry out this study, this research draws upon interdisciplinary theories from political psychology, critical security studies, and queer theory, with a particular focus on Lacan's concept of fantasy along with the

This thesis investigates the application of machine learning and statistical methods for forecasting hourly public transport validations using ticket‐validation data. After cleaning and aggregating validations into hourly counts, temporal features such as hour of day, weekday, and month are engineered. The modeling approaches include long short‐term memory networks trained with mean absolute error

This thesis explores how dialogue functioned as a practice of knowledge circulation within the International Dialogue Project (1977–1988), an ambitious and largely overlooked initiative led by Anne Buttimer and Torsten Hägerstrand. Conceived as an effort to bridge generational, disciplinary, and geographic divides, the project produced over 150 video-recorded interviews with senior scholars from v

The product space conditions the process through which economies become complex and develop. Does it also condition aid effectiveness? This thesis examines the relationship between technical cooperation (TC) and economic complexity and brings a novel perspective by documenting that the complexity opportunity index (COI) significantly enhances the association. Employing fixed effects panel regressi

Denna studie undersöker om maskininlärning kan användas för att förbättra bedömningen av rehabiliteringsövningar. Resultatet visade att metoden har potential, men att det krävs ytterligare studier för att utveckla en användbar lösning. Rehabiliteringsövningar är en viktig del av återhämtningen från skador och för att den ska bli korrekt krävs hjälp från en fysioterapeut. Fysioterapeuten guidar paRehabilitation exercises are essential for recovery from many injuries, and their practice is guided by physical therapists in order to avoid the risk of further damage. The physical therapists have limited tools for conducting a quantified assessment of movement quality and this study investigates whether machine learning could be used to improve that process. A way to assess movement is to analy

Introduction: Cancer is classified into several stages, being more difficult to cure in later stages. Thus, early detection is important. This project aims to help the development of a non-invasive method for early cancer detection using hair samples. Background: Isotopes are known to leave a temporary and geographical signature in different samples. Capillon Analytics AB uses isotopes to detect c
