In this thesis, initiated by Axis Communications, the material choice of a folded horn loudspeaker was investigated. The main goal of the project was to determine if it was possible to reduce the costs and environmental impact of the product by means of optimizing the material, while maintaining or improving its performance. The three main parameters which were analyzed were the acoustic performan

This thesis presents a way of representing electric and magnetic fields directly as linear combinations of products of components of Weyl spinors, without using a four-potential. First it is shown that when Lorentz transforming the spinors, these fields transform according to the tensor transformation of the electromagnetic fields. Then, by explicitly expressing the spinors in terms of a four-mome

This paper explores the Klein-Gordon equation, a relativistic wave equation. More specifically, it studies the free form of the equation, where the potential is set to zero. The partial differential equation, together with initial conditions, forms an initial value problem. The first goal of the paper is to derive the Green's function for the problem. This is done in several ways, using spectr

This thesis investigates what drives people to use credit-style Buy Now, Pay Later (BNPL) services, focusing on Klarna users in Sweden. Drawing on behavioral economics, it tests whether having a present-biased time preference (a strong preference for immediate rewards) can predict a person’s use of Klarna’s “Pay Later” and “Installments” features. To explore this, a cross-sectional survey (N =100)

This thesis examines the role of visual media in conveying the Gallic founding myth and constructing national identity in nineteenth-century France. Positioned at the interdisciplinary intersection of nationalism studies and memory research, it investigates how visual representations embed the Gallic founding narrative – despite its association with military defeat – into France’s collective memor

Studien syftar till att kartlägga entreprenörers anbudsprioritering och ge offentliga beställare kunskap om marknaden för att kunna anpassa sina förfrågningsunderlag. Studien har genomförts som en kvalitativ studie innehållande litteraturstudie, dokumentstudie och intervjustudie. Tre administrativa föreskrifter, AF-delar, har analyserats i dokumentstudien. I intervjustudien har både entreprenad-fThe study aims to map contractors’ bid prioritization and provide public clients with knowledge about the market to be able to adjust their tender documents. The study was conducted as a qualitative study including a literature review, document study, and an interview study. Contractual tender documents were analyzed in the document study. In the interview study, both contractors and public procu

Bakgrund: Antalet människor som på olika sätt påverkas av naturkatastrofer, krig eller konflikter ökar. Dessa katastrofsituationer medför att de som drabbas får inskränkt möjlighet att engagera sig i viktiga och meningsfulla aktiviteter. Arbetsterapeuter har kompetens om hur person, miljö och aktivitet samspelar och kan bidra till arbetet i samband med katastrofsituationer och med katastrofdrabbadBackground: The number of people affected by natural disasters, war, or conflicts is increasing. These disaster situations limit the ability of those affected to engage in important and meaningful activities. Occupational therapists have expertise in how person, environment, and activity interact and can contribute to efforts related to disaster situations and people affected by them. Aim: The aim

Per- and polyfluoroalkyl substances (PFAS) are persistent synthetic chemicals widely used in consumer and industrial products. Increasing evidence of their adverse health effects has intensified the need to understand their impact on human immune function. This study assessed PFAS toxicity using a human dendritic cell model by focusing on gene expression and surface marker modulation, as well as a

The Arctic has increasingly emerged as a geopolitical horizon shaped by environmental, security and economic transformations. As sea ice melts and military and commercial interests materialise, questions arise about how the region is discursively constructed by various stakeholders. With the Arctic Council in flux, alternative forums have gained significance as sites for dialogue and public diplom

This thesis is looking at Sweden’s implementation and priorities of the 2030 Agneda and specifically SDG 3 pertaining to health and wellbeing. It explores how national and international dynamics influence Sweden’s commitment to SDG 3, by examining shifts in political leadership and the developments within the global governance system. Placing Sweden within the broader context of global health gove

The European Union’s sustainability reporting framework, which includes the CSRD and the CSDDD, is widely regarded as a logical progression toward achieving the 2050 climate goals. The EU has faced criticism regarding the sustainability reporting directives, primarily due to concerns over the EU’s global competitiveness and the readiness of undertakings to comply. Consequently, there have been inc

Antimicrobial resistance (AMR) and natural hazards and associated disasters both pose significant global threats, with potential for exacerbating intersections. Despite AMR’s growing international priority, the nexus of AMR and hazards/disasters remains underexplored. This thesis aims to provide a comprehensive overview of the nexus to inform future perspectives and highlight further investigation

This thesis provides a comparative analysis on sustainability chapters in free trade agreements (FTA) from the EU and Australia. It then evaluates the implication this comparison has in light of EU-Australia FTA negotiations. In addition to this, the text utilises a funnel approach by examining broader concepts in order to help answer the research question. This includes the definition of free tra

Artificial Intelligence has existed for many years and keeps developing. AI has become better at generating new works, for example music, which raises a question of whether AI can potentially infringe on copyright. This thesis examines the legal framework regarding copyright and AI and whether AI used in music can constitute a copyright infringement. The question that is focused on is “To what ext

An emerging research topic in quantum thermodynamics is the study of entangled quantum heat engines, where the working medium consists of an entangled quantum system. These engines offer exciting platforms for exploring fundamental aspects of quantum thermodynamics, its intersection with quantum information theory and the nature of entanglement in general. In this bachelor’s thesis, the performanc

This study examines the determinants of player salaries in Europe’s top five men’s football leagues (Premier League, La Liga, Serie A, Bundesliga, Ligue 1), focusing on the impact of player representation models for forward players. We compare players represented by football agencies versus those represented by relatives, and explore whether agency size affects salaries. Drawing on principal-agent

This thesis aims to characterize and counteract the wave steepening effect in a horn loaded loudspeaker. The report consists of two main parts. The first part, the characterization of the horn speaker system, focuses on investigating and understanding the signal distortions introduced by the speaker system. In particular, non-linear distortion is examined to determine any parameter dependence of t

Ovarian cancer is among the most lethal gynecological malignancies, with high-grade serous ovarian cancer (HGSOC) being the most aggressive and prevalent subtype. This heterogeneous disease is typically diagnosed at an advanced stage and is associated with high relapse rates. Increasing attention is being directed toward the tumor microenvironment (TME), a complex and dynamic network of non-cancer

Transformation as an adaptation response can help align risk aversion practices with goals of sustainability and social justice. This lies in its ability to drive deep reaching changes in socio-environmental structures through critically examining and restructuring dominant power structures. This thesis applies Pelling et al’s (2015) transformative adaptation framework to a case-study of a technol
