Preliminary Design for a Mobile Ammonia Genset for Use with Electric Mining Excavators

Given global temperatures are expected to rise past the Paris Agreement’s 2°C limit, Liebherr Mining aims to develop products that progress their Zero Emission Mining strategy. This project therefore selected the major components required by a mobile ammonia-fuelled genset under certain operating conditions and assessed the proposed design against existing solutions. The project was built on find

Interaction Shifting Identity: The Dynamic Identity Construction of Chinese Women through the Pursuit of Thinness on Social Media

This thesis investigates the interaction of the "thinness is beauty" concept on Chinese women's social media, the rise of anti-body anxiety content, and their effects on female identity formation and consumer behavior, focusing on fast fashion brands and Red. It aims to explore the factors reinforcing narrow beauty standards, analyze changes due to anti-body anxiety content, and exam

Luft, vatten och saltvattens inverkan på asfalt över tid

Denna studie åsyftar att utreda hur saltlösning påverkar vanliga slitlager i kontrast till hur luft samt vatten påverkar slitlager. Slitlagerna representerades av asfalttyperna asfaltbetong, dränerande (ABD11 70/100) vilken är en dränerande beläggning samt asfaltbetong, stenrik (ABS11 70/100) som är en tät beläggning. ABD och ABS användes i experimentet eftersom ABD har en högre hålrumshalt än ABSThis study aims to investigate how salt solution affects typical road wear courses in contrast to how air and water affect road surfaces. The wear layers are represented by the asphalt concrete Porous Asphalt (PA or ABD11 70/100) which is a draining road surface and Stone Mastic Asphalt (SMA or ABS11 70/100) which is a dense road surface. PA and SMA were used as contrasts to use in the experiment

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
