Objective: To limit the research time by developing a theoretical model, that can predict the lifetime of a wheel with the help of different input values. Apart from a theoretical model, also create a different type of test rig that can decrease the testing time, and still produce an accurate result similar to a real situation. Method: This Master’s Thesis was based on both an investigatory method
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
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
This master’s thesis has examined the feasibility of an accumulator-based actuation method for the BorgWarner (BW) electric torque vectoring and disconnect (eTVD) system. The requirements for the proposed concepts were defined based on the performance of the baseline eTVD and served as reference criteria throughout the development process. A strong emphasis was placed on reducing system complexit
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
Bacterial infection and hemorrhage remain significant clinical challenges for chronic wounds, despite advancements in antimicrobial strategies and materials. Herein, 980 nm-laser-responsive photothermal conjugated polymers (CPs) are combined with chitosan-based cryogels (CP@Gel) to achieve rapid hemostasis and efficient anti-infectious performance. CP nanoparticles (CP NPs) were prepared by nanopr
Continuous non-invasive monitoring of respiratory rate in laboratory mice can support research across drug efficacy, sleep, and stress and pain assessment. Established respiratory rate estimation methods exist but many conflict with the 3Rs principle through invasiveness, motion restriction, or animal stress. A cross-method comparison between two non-invasive systems on the same freely-moving anim
The expansion of the European Union's (EU) regulatory sphere creates conflicts of sovereignty between the EU and its member states, and third countries that lack a possibility to participate in the making of those laws and policies. The conflict is epitomised in the concept of the Union's decision-making autonomy. Albeit stringently applied, the concept is ambiguous and undefined. This article end
Lagging fires, also known as insulation fires, pose significant risks in the process industry, arising from the self-heating of leaked combustible liquids within insulation materials. These fires typically initiate through oxidation, leading to smouldering that can escalate into larger fires or serve as ignition sources for other flammable materials. Statistics from the Swedish Contingency Agency
In northern countries, the climate, and consequently the use of studded tyres and winter traction sanding, causes accumulation of road dust over winter and spring, resulting in high PM10 concentrations during springtime dusting events. To quantify the dust at the road surface, a method—the wet dust sampler (WDS)—was developed allowing repeatable sampling also under wet and snowy conditions. The pr
