The master’s thesis includes a torsional vibrations analysis of an engine crankshaft and transmission in a hypercar. A torsional model is implemented in order to analyze how excitations produced by the engine affect the vibrational dynamics of the system. This is done by analyzing resonance frequencies and response amplitudes at critical speeds. A frequency-domain driven Python model is built in p
Steam and water chemistry is fundamental for most power generation on indus trial scale. This includes the dosing of chemicals, the monitoring of both water and steam, as well as understanding the underlying causes to diagnose eventual problems. Öresundsverket, which was designed for seasonal operation, now has to perform multiple starts per year and in meeting these demands there is a possi bilit
Metasurfaces are two-dimensional arrays of sub-wavelength structures often arranged in a periodic lattice. During recent years, metasurfaces have emerged as one of the most promising platforms to shape electromagnetic waves using compact devices, exhibiting extraordinary control over the light amplitude, polarization and phase. Starting with metallic materials, metasurface research has shifted tow
This thesis explores the legal uncertainty surrounding the sharing of machine-generated operational data, with a specific focus on data produced by the Integrated Control System (ICS) at the European Spallation Source (ESS). It establishes the basis for a comprehensive data-sharing framework that bridges internal operations with external access rights. To achieve this, the thesis analyses why raw
Utsläpp av lustgas från avloppsreningsverk (ARV) utgör en betydande klimatpåverkan och är starkt kopplade till utökad biologisk kväveavskiljning. Syftet med detta arbete har varit att analysera sambanden mellan processparametrar och lustgasutsläpp vid Klagshamns av-loppsreningsverk samt att undersöka hur datadriven modellering kan användas som stöd för driftoptimering. Inledningsvis genomfördes en
While accessibility in building design is now a widely adopted principle with the industry increasingly adopting inclusive practices, its integration into evacuation provisions remains limited and inconsistently applied across the world. This study examines gaps in evacuation design practices affecting occupants with disabilities through a comparative review of ten building codes and standards, su
Rå biogas är varm, mättad med vatten och innehåller små mängder av korrosiva spårämnen när den lämnar rötkammaren. I detta skick kan gasen inte levereras till uppgraderingsenheten som tar bort koldioxid, vattenånga och andra föroreningar för att leverera biometan som uppfyller fastställda kvalitetskrav. Den höga fuktigheten kombinerat med reaktiva ämnen leder till okontrollerad kondensation och koRaw biogas leaving an anaerobic digester is warm, saturated with water vapor, and contains small amounts of corrosive trace compounds. In this state, the gas cannot be fed directly to an upgrading system, where carbon dioxide, water vapor and other contaminants are removed to produce biomethane that meets a predefined quality. High humidity combined with reactive species promotes uncontrolled cond
This thesis investigates how Vietnamese students in Germany explain the reasons for their choice to study there. It draws on Bourdieu’s field theory, and analyses data from eight semi-structured interviews. It quickly became apparent that all the students interviewed had specific, pre-existing social and cultural capital related to Germany. In terms of outcomes, all are focussed on gaining a highl
This thesis investigates whether Large Language Models (LLMs) can meaningfully reason over natural language event context to produces calibrated adjustments to time series forecasts, and under what conditions that reasoning produces reliable signal. We design an agentic forecasting system in which the LLM acts as a strategic orchestrator rather than a direct numerical predictor: all numerical comp
Mobile connectivity is set to change in the coming years due to AI generated data from agents and robotics. How this will develop remains uncertain since this type of data generation is not only a question of connectivity but also compute location and use cases. This creates a need for forward looking scenario analysis for ecosystem players so they can position themselves to win in a new paradigm.
Fossil fuel companies have shifted from outright climate denial to subtler strategies of delay. These include low-carbon solutions — carbon capture, utilisation and storage (CCUS) and hydrogen — which legitimise and extend fossil fuel dependency. This study examines how low-carbon discourses operate through the media in Singapore, a major refining and petrochemical hub with an authoritarian state-
Introduction: Enzyme-based approaches have shown promise in a more targeted alternative for treating oral diseases such as caries. Given the high global prevalence of caries, and ecological complexity of the oral microbiome, investigating selective treatment strategies is of significant interest. Background: The oral microbiome is a dynamic, polymicrobial community, dependent on ecological balance
This thesis examines the regulatory framework governing Buy Now, Pay Later arrangements within the European Union, with a particular focus on consumer protection. Buy Now, Pay Later has rapidly emerged as a popular payment method in digital commerce, especially following the growth of online shopping during and after the COVID-19 pandemic. While the service provides consumers with accessible
The governance of Ålakusten’s eel fishery reveals a growing tension between species conservation and the safeguarding of intangible cultural heritage. Using a qualitative case study design, this thesis combines a social-ecological systems analysis of policy documents with a critical heritage studies analysis of oral histories and an expert interview to examine how eel fishing is governed and repre
Följande studie handlar om folkmusiklärares perspektiv på sin yrkesroll och utförande av undervisningen. Inspirationen bakom detta examensarbete ligger i författarnas delade nyfikenhet kring den pedagogiska aspekten av folkmusikutövande i Sverige och vad lärarrollen innebär. I studien undersöks lärarens roll och yrkesutövande i relation till identitet och musikerskap, didaktiska metoder, tradition
The documented adverse effects of climate change have led to national and international efforts to reduce global carbon emissions during recent decades. Significant decarbonisation requires not only a reduction in the production and use of fossil fuels, but a transformation of the entire energy system itself, transitioning away from fossil fuels to renewable energy sources. This large-scale transi
Reproducing the spatial acoustics of a room is key to the feeling of spatiality of audio in headphones, with applications in, for example, cultural preservation. The propagation of sound between a point source and a receiver in a room is commonly modelled as a linear time-invariant system, where its room impulse response fully models how sound propagates. By combining the room impulse response and
Wildfire management is a complex sociotechnical system where enterprise and strategic level decisions significantly impact operational safety. This research explores iterating Rasmussen’s AcciMap through participatory co-design to enhance sensemaking and systems thinking in the U.S. Forest Service. An evolving series of AcciMap-inspired visualizations made from the Eicks Fire Organizational Report
Osteoarthritis is a multifactorial degenerative disease characterized by the breakdown of articular cartilage (AC), affecting hundreds of millions of people worldwide. Among many treatment options, hydrogels have emerged as promising candidates for cartilage replacement, due to their structural resemblance to the native tissue. Hydrogels can be made from various materials, and this study focuses o
This thesis assesses the efficiency of the EU Law’s balancing act between the software developers’ copyright protection on their respective computer programs and the software users’ right to repair their defected software based devices. This research necessitates an EU legal method, implying the comprehensive analysis of EU legislation and the case law of the Court of Justice of the European Union
