A comparison is made between the development trends experience over the last decades by the steel and papermaking industries, respectively. These two industrial branches, although totally different in their technical nature, are subject to similar pressures from their external environment, notably increasing requirements for environmental protection and more efficient raw material management. Such
Whole-lake additions of dissolved inorganic C-13 were used to measure allochthony (the terrestrial contribution of organic carbon to aquatic consumers) in two unproductive lakes (Paul and Peter Lakes in 2001), a nutrient-enriched lake (Peter Lake in 2002), and a dystrophic lake (Tuesday Lake in 2002). Three kinds of dynamic models were used to estimate allochthony: a process-rich, dual-isotope flo
This thesis aims to explore the possibility of using deep learning techniques to mine opinions on Twitter, with the objective to predict the political opinion distribution in Sweden. Different methods of gathering and annotating training data are evaluated to achieve accurate and reliable predictions. The models are quite successful at predicting test data, achieving F1-scores in the range of 70 %
Air traffic control (ATC) is a safety-critical activity in which practitioners must continuously navigate uncertainty, trade-offs, and operational variability. In such environments, resilience emerges not from strict adherence to procedures alone but from the adaptive strategies that air traffic controllers employ to sustain safe performance. One striking property of air traffic control is that co
This study examines the linguistic characteristics of the speech of female villains in Japanese fictional dialogue, with the aim of determining whether female villains employ a distinct role language or yakuwarigo, that is, a distinct speech style that indexes characterization based on social stereotypes. An original, small-scale corpus was constructed consisting of dialogue from female villains,
The archaic witch Circe from Greek mythology has been an enduring figure in history in Western literature and English-speaking cultures. The character has undergone multiple adaptations and is seemingly restricted to the archetype of a villainous femme fatale, symbolising the threat of wilderness and female sexuality. In Miller's novel Circe (2018), the character undergoes another transformati
This thesis investigates probing antennas within a small shielded test enclosure for IoT, Internet of Things, products for the detection of manufacturing deviations. The small enclosure forces the transmitter and receiver to be in the near-field. Shielding of the enclosure additionally generates a multipath environment, which becomes sensitive to displacements of objects such as wires or metallic
In January 2025, following renewed threats of a TikTok ban in the United States, over half a million users migrated overnight to RedNote (also known as Xiaohongshu), a Chinese lifestyle-sharing platform. This unexpected influx marked the first large-scale digital migration from a Western user base into a Chinese social media space. Among these users, who are self-described as “TikTok refugees”, a
Physical activity is essential for health and well-being, as recognized by the World Health Organization (WHO), which defines it as any bodily movement produced by skeletal muscles that requires energy expenditure. Recommended levels of physical activity vary depending on age, with children needing at least 60 minutes per day and adults requiring 150–300 minutes of moderate-intensity activity per
The needs and wishes of older people have often been forgotten in urban planning in recent decades. Yet already today, more than one billion of the world‘s population is over 60 years old, and according to the World Health Organisation (WHO), one in six people will be over 60 by 2030 - an increase to 1.4 billion by 2030 and up to 2.1 billion by 2050 (WHO, 2024). Like many European countries, Switz
Aviation in Europe has undergone an enormous change from national rulemaking to common European rulemaking. Behind this change is the European Union’s decision to delegate some policy implementation functions to decentralised agencies. The European Union Aviation Safety Agency (EASA) is one of these EU agencies and has specific authorisation to implement decisions that directly impact individuals,
This research report was carried out in collaboration with Qlik AB and aimed to identify what aspects are needed from a software platform in order for developers to want to use them. It also aimed to identify how well the software platform Qlik Core had implemented these aspects. The research used online questionnaires, interviews and data analysis using Qlik Sense. The research compared how diffe
Authors: Ellinor Lantz & Linn Modée This thesis has been a complete collaboration between the two authors. Each author has been involved in every part of the process and contributed equally.

We introduce the basic theory of vector-valued reproducing kernel Hilbert spaces, and use this language to prove the classical Pick interpolation theorem using the commutant lifting theorem applied to operators on the Hardy space H^2(D). Two very general versions of the commutant lifting theorem due to Shimorin are then proved for vector-valued reproducing kernel Hilbert spaces, and as a corollary
Konfigurerbara system, såsom Tactels Android-baserade In-Flight Entertainment lösning, erbjuder stor flexibilitet men utgör samtidigt en utmaning för användartestning på grund av det oändliga antalet möjliga konfigurationer. För att säkerställa en bra användarupplevelse undersöker detta arbete möjligheten att använda Artificiell Intelligens, mer specifikt maskininlärning, för att förutspå användarConfigurable systems, such as Tactel’s Android-based In-Flight Entertainment solution, offer great flexibility but also present a challenge for usability testing due to the infinite number of possible configurations. To ensure a good user experience for each configuration, this study explores the possibility of using Artificial Intelligence, more specifically machine learning, to predict users’ ex
This thesis wants to investigate whether machine learning, trained on candlestick data, can be used to forecast intraday returns. Previous research has primarily focused on returns with longer horizons and is therefore leaving a research gap on shorter horizons. This thesis will use a combination of Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM) as the deep learning model to
Key actions, tactical cooperation, and spatial relationships in sports activities are usually recorded through 2D videos, which limits users’ ability to understand the game in three-dimensional space. Although professional sports events can provide Free-Viewpoint Video using large-scale camera arrays, such systems are difficult to deploy in low-cost scenarios such as community games and personal t
This thesis investigates the design and evaluation of Large Language Model (LLM) agent assistants for industrial maintenance, developed in cooperation with SSAB. The study focuses on identifying what combinations of tools and architectures best serve the needs of maintenance technicians, with an emphasis on practical usability and factual correctness. Multiple agents were developed and compared,
Background The aim of this systematic review and meta-analysis was to examine autoantibody positive individuals and define: (a) the relative risk of rheumatoid arthritis (RA) compared with autoantibody negative individuals and (b) the cumulative incidence of RA over time, in different populations. Methods A systematic literature search was performed in August 2025. Retrospective case control studi
