Simulation of Screening ECG data for Training of ML-based AF Detectors

Simulerad patientdata och AI för förbättrad upptäckt av förmaksflimmer År 2030 förväntas upp emot 17 miljoner människor i Europa lida av förmaks-flimmer, en sjukdom med mycket allvarliga konsekvenser. Denna studie utforskar användningen av simulering och maskininlärning för att effektivisera diagnostiseringen, och därigenom potentiellt förebygga uppemot 20% av alla strokes. I Sverige uppskattas Atrial fibrillation (AF) is an arrhythmia distinguished by irregular heartbeats, which has seen a significant rise in prevalence globally. Due to the risk of strokes, the condition necessitates early detection and intervention to prevent severe complications, highlighting the critical role of early and precise detection techniques. To effectively train and validate machine learning (ML) models, ha

Soup and Glue - A Recipe for Fighting Climate Change: an investigation into the weaponisation of art by climate activists

This thesis aims to investigate the newly emerging phenomenon in the environmental justice sphere – namely, the weaponisation of art by climate activists for the purpose of attracting attention to specific demands held. These attacks materialise in the form of organised acts wherein tactics entailing vandalism are enacted by a climate activist group. With the commencement of this climate movement

Museums as Duty-Bearers of Human Rights: Shifting Museological Practice and the Assertion of a Regulatory Governance Model

For decades there has been a push to bring museums into alignment with current thought on how history can be shared in a way that is more relevant for society today. This thesis draws on recent thought and theories of practice in museums that coincide with these shifting perspectives, centering on the questions of how museums are already acting as de facto human rights duty-bearers, and how they m

Towards an experimental implementation of the Sorkin test with photoelectrons

Kvantmekaniken är den fysik som beskriver våra minsta partiklar - en mikro-skopisk värld där fenomen som inte alls är naturliga i vår större värld existerar. Genom att undersöka "interferens", ett fenomen som endast vågor och inte partiklar kan ha testar vi kvantmekanikens lagar med attosekundfysik. Människan har länge försökt förstå hur världen fungerar, redan i antikens Grekland fundeQuantum mechanics is used to describe the world at the microscopic scale and below. It is also the theory that has been the most debated but also the one whose predictions has been tested with the highest accuracy. This theory relies on a set of postulates that lay the foundations for all its predictions. One of these postulates is Born’s rule, which defines the probability to measure a quantum sy

Trigger-Level Electron Counting in the Light Dark Matter eXperiment using Artificial Neural Networks

The Light Dark Matter eXperiment is a fixed target missing-momentum experiment that searches for light dark matter production via the process of Dark Bremsstrahlung by analysing the energy of beam electrons after they hit a tungsten target. Electron counting is an important part of the experiment as this forms one of the two components of the missing energy trigger. The thesis looks into viability

Improving Loudspeaker Characteristics in a Low Power Environment

This master's thesis explores the improvement of loudspeaker characteristics by using digital signal processing. The main aim of the thesis is to improve the overall audio quality with regards to limited processing power and power supply. Improving the audio quality is important since the vast expansion of the usage of loudspeakers has led to demands on cost, size and design choices all leadin

Försvarsmekanismer mot Cancelkulturen: En kvalitativ studie av Logan Pauls kontroverser och åtgärder

The aim of this study is to investigate different types of crisis management strategies in relation to cancel culture scandals involving influencers. It is conducted through two case studies of scandals regarding Logan Pauls, one that happened in 2017 and the other one 2023. To be able to draw scientific conclusions regarding what type of strategies Logan Paul used, the study adapts three theoreti

Exploring Civilian Service: An alternative approach to mitigate Labor Shortages in the Long-Term Care Sector

Population aging and labor market variables exacerbate the labor shortage in the Long-term care (LTC) sector in many European countries. In Sweden, existing strategies to manage this issue are questioned. This paper investigates an alternative solution: civilian service, inspired by Austria and Germany, where civilian service complements military service and allows civilian servants to work in the

Masking Out Transient Network Issues in Sound Playback

Significant advancements in audio transport, encoding, and processing power in embedded systems constitute the foundation of today’s speakers. Transitioning the digitalized audio data transmission to Audio over IP (AoIP) has opened the potential to transmit audio with the same network flexibility as other services using packet-based networks, such as voice over IP or video over IP. This thesis pri

The Hitchhiker’s Guide to XR: Novel Methods to Lower the Barriers for Novice Developers

The growing popularity of Extended Reality (XR) attracts new people to enter the field. However, novices face challenges at the beginning of their journeys. Previous studies have identified the key difficulties based on real-world evidence and found that the barriers to entry were high. This thesis aims to guide novice XR practitioners in overcoming these challenges. To achieve this, empirical in

Reclaiming the Southern Shoreline: A regenerative transformation along Göta Älv in Gothenburg, Sweden

Studies show that urban highways play a vital role in facilitating transportation within metropolitan areas, yet they often come with significant drawbacks, including physical barriers, urban decay, and environmental degradation. In Sweden, where the transport sector is a major contributor to greenhouse gas emissions, the city of Gothenburg stands as a prime example of these challenges. Located a

Optimising diagnostic strategies for the early detection of Parkinson’s disease, using seed amplification assays

Background: Parkinson’s disease (PD) is the second most common neurodegenerative disease, and it is linked with aggregation of α-synuclein protein. PD can be diagnosed using real-time quaking induced conversion (RT-QuIC) assay. RT-QuIC, despite its effectiveness, is not really understood in terms of the mechanisms driving it. Aim(s): The aim of the project was to reproduce RT-QuIC protocol develop

Automatisering av kalibreringsförfarande för momentgivare

When using measurement equipment, it is not only important to use the right equipment for the job, but to also make sure that it is measuring correctly. Electronic devices, as well as mechanical devices, all deteriorate over time. This leads to a need for calibration at a regular interval. By calibrating a measurement device by comparing its measurements to a verified reference device, it is possi

"På papper kan det verka vara en enkel arbetsuppgift" - En kvalitativ studie om smittspårning ur kuratorns perspektiv

This study aimed to research the phenomenon of contact tracing of sexually transmitted infections through the perspective of healthcare social workers. The research questions were what competencies could contribute to a satisfactory contact tracing and whether these competencies corresponded to those the health care social worker typically has. This was researched using a qualitative research meth

Towards single-scan quantum state tomography of photoelectrons

När ljus med tillräckligt hög energi träffar ett material kan en elektron frigöras från materialet. Detta beskrevs av Einstein i början av 1900-talet som den fotoelektriska effekten. Genom att mäta rörelseenergin hos de frigjorda elektronerna, eller fotoelektronerna, kan man avgöra egenskaper hos olika material. Dessa mätmetoder baseras på att fotoelektronen är en partikel, men den är också ett Today's gold standard for measuring the quantum state of a given quantum mechanical system is quantum state tomography. By preparing many identical states and performing projective measurements on them, their quantum state, described by the density matrix, can be reconstructed. A protocol called Kvanttillstånds-tomogRafi av AttoseKund-ElektroNvågpaket (KRAKEN) has been developed to perform qua
