Insect populations have decreased dramatically the past decades, with one reason being unintentional pressure from pesticides. Insecticides such as neonicotinoids can cause sub-lethal effects in insects, such as altered metabolic regulation, which can be studied using targeted metabolomics. Although commonly studied using High-Performance Liquid Chromatography tandem Mass Spectrometry (HPLC-MS/MS)
This thesis explores how sustainable entrepreneurs adapt their motivation and identity amid the emotional, moral, and strategic tensions of building purpose driven ventures. While previous research has examined motivation and identity separately, little attention has been paid to their interdependence, particularly in high uncertainty environments where values and viability collide. Integrating Se
This thesis explores the classification of savannah trees using EnMAP hyperspectral and Sentinel-2 multispectral satellite data using a Random Forest classifier. The study aimed to assess if the increase in spectral information from the hyperspectral data gives an increase in classification performance, to find the advantages and limitations to hyperspectral data compared to multispectral data and
Myoelectric prosthetics utilize machine learning(ML) algorithms to translate surface electromyography(sEMG) signal patterns into movement, allowing patients to easily control their prosthesis. While the use of conventional ML algorithms has been effective within these prosthetics, challenges still remain in terms of classification accuracy and computation speed. It was hypothesized that Kolmogorov
Purpose: The purpose of this study is to explore how consumers navigate and justify their consumption habits while striving for a more sustainable identity. The study examines the internal dilemmas that arise when sustainable values confront the realities of identity expression and social influence. Methodology: A qualitative research approach was adopted, in the form of in-depth interviews, invo
Impact investing is a recently emerged field which aims to combine the goal of achieving financial returns with positive environmental or social impact. The documented loss of biodiversity has caused the emergence of many corporate environmental impact reporting frameworks, which have sometimes been criticized for their lack of biodiversity-outcome indicators. This study aims to take stock of the
The objective of this thesis is to investigate the feasibility of constructing temporary warehouse halls using glulam (glued laminated timber) frames, as well as to explore alternative solutions to PVC fabric for roofing and walls. The background is an increasing demand for temporary and flexible ware- house structures across several industries, along with a growing interest in environmentally fr
Deforestation is one of the most significant environmental challenges, with close links to global issues such as biodiversity loss and climate change. The European Union Deforestation-free Products Regulation (EUDR) introduces rigorous due diligence obligations for companies placing forest-risk commodities and derived products on the European market, intending to halt global deforestation. Despite
We live in an increasingly individualistic society where involuntary loneliness, especially among older adults, has become a growing issue. In Sweden, where single-person households are common, many seniors, particularly those over 65 who live alone, report feeling lonely. At the same time, children are growing up with limited contact with older generations, as everyday interactions between age gr
This thesis critically examines the Swedish ‘Security Zones’ legislation, the associated governmental discourse on organised criminality, and their implications for equality and racial justice. Through a critical discourse analysis, the thesis illustrates how the extended discretion afforded through the legislation facilitates law enforcement’s capacity for racial profiling and discrimination. It
Clay boards are emerging as a sustainable alternative to gypsum boards for fire protective linings in timber structures. However, their fire behaviour is still not well understood. Most existing studies focus on full scale systems, which show when a board fails but not why it fails. This thesis addresses this gap by investigating two commercial clay board variants with different compositions, dens
This thesis explores the visual and cultural representation of worldbuilding in fantasy genre video game trailers. The focus is to find out to what extent video game trailers in the fantasy genre utilise visual tropes and cultural representations to establish an identity as fantasy video games. It is well established that game developers look for inspiration in the real world when creating new one
Industrial pasteurisation is a heat-intensive process with significant potential for decarbonisation. This study investigates how open-source Modelica libraries can be adapted for industry, especially for food industry, and integrated to replace fossil-based thermal systems. Investigations are done to evaluate models of heat pumps, thermal energy storage, specifically the stratified tank, and sol
Network cameras observe physical spaces but lack an inherent understanding of the scenes they see. This thesis presents a pipeline for floor and wall instance segmentation from a single uncalibrated RGB image, requiring no scene-specific prior information such as camera intrinsics, depth sensors, floor plans, or labelled floor and wall data for training. The detected instances are intended to supp
Electronic Image Stabilization is a method to digitally stabilize a video feed to remove unwanted motion by transforming the image. The aim is to create a better viewing experience, reduce bitrate, and simplify further video analytics. This thesis explores different algorithms to stabilize Pan-Tilt-Zoom surveillance cameras made by Axis Communications. Many scenarios are investigated, but the case
Förarapplikationer används i allt större utsträckning hos yrkesförare för att stödja företags ruttplanering, orderhantering, dokumentation och intern/extern kommunikation. När förare behöver läsa, tolka och/eller interagera med information i situationer kopplade till körning kan dessa system även skapa visuell, manuell och kognitiv distraktion, vilket ökar risken för trafikrelaterade skador. DettaDriver applications are increasingly used in professional driving to support route planning, order management, documentation, and communication. When drivers need to read, interpret, or interact with information in close proximity to driving, these systems can also create visual, manual, and cognitive distractions, increasing traffic safety risk. This master's thesis was conducted in collabora
The Period genes (Per) play essential roles in modulating the molecular circadian clock timing in a broad range of species, which regulates the physiological and cellular rhythms through the transcription-translation feedback loop. While the Period gene paralogs are widely observed among vertebrates, the evolutionary history and the functional diversification of Per genes across vertebrates are no
As the first domestic species, dogs likely dispersed with different cultural groups during the Late Pleistocene and Holocene. To test this hypothesis, we analyzed 73 ancient dog genomes, including 17 newly sequenced individuals sampled from East Asia to the West Eurasian Steppe spanning nearly 10,000 years. Our results indicate correlations between the ancestry of dogs and specific ancient human p
Wind generation’s growing share of Nordic electricity supply has made imbalance settlement an increasingly costly exposure for producers. Under the Nordic single-price mechanism, all residual imbalance is settled at a single imbalance price, regardless of direction, determined by the mFRR activation market. Before that price is known, the producer fixes a day-ahead position, adjusts on the continu
