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
Med utgångspunkt i den ökade utbrändheten och den skenande klimatkrisen fokuserar denna studie på skogsbad som en arena där båda problem kan hanteras. Genom Hartmut Rosas resonansteori konceptualiseras dessa problem som en effekt av en skadad relation mellan människa och värld. För att hantera problemet krävs därför en förbättrad relation till världen, en relation som Rosa beskriver som resonant.
För att byggbranschen ska kunna uppnå de klimatmål som satts upp måste det ske en förändring. Förändringarna måste bidra till minskade utsläpp samtidigt som den byggtakt som krävs upprätthålls. Idag står bygg- och fastighetssektorn för mer än en femtedel av Sveriges koldioxidutsläpp, där värmeisoleringen är en bidragande orsak till utsläppen. Genom att byta ut konventionell isolering och istället For the construction industry to meet the established climate targets, a transformation is necessary. These changes must lead to reduced emissions while maintaining the pace of construction. Currently, the construction and real estate sector accounts for more than one fifth of Sweden’s carbon dioxide emissions, with insulation being a contributing factor. By replacing conventional insulation with
This research studies vegetation dynamics in the West Bank under ongoing occupation using Sentinel-2 satellite imagery and the Normalized Difference Vegetation Index (NDVI). Using annual NDVI composites from 2017 to 2024, the NDVI change across Area A, B and C, areas with different control established during the Oslo agreements, were studied. The results show broadly uniform NDVI patterns across t
As generative artificial intelligence (“AI”) rapidly transforms sectors, regulators are racing to keep pace with technologies that evolve faster than legal frameworks can adapt. These systems, powered by large language models or foundation models, are not only capable of generating human-like content but also demonstrate behaviors that shift depending on their data, deployment, and interaction con
This thesis examines whether the current EU competition law framework, particularly Articles 101 and 102 TFEU, is sufficient to regulate algorithmic collusion. As pricing algorithms become more autonomous and capable of producing supra-competitive outcomes without direct human input, concerns arise about whether such behaviour fits within existing legal categories like “concerted practice” or “abu
This study aims to understand and contribute to the general knowledge of the experiences and perceptions of social services officials working in the public social service sector in a relatively small municipality in Southern Sweden, regarding changes made to the workflow as a consequence of reorganization within the unit for adult care initiatives. This premise provides a good overview of the char
In the context of the current climate crisis and a growing need for electricity, renewable energy plays an important role. Repowering means upgrading existing renewable energy production with new, more efficient technology to increase production in older sites. Wind-power technology has developed significantly in the last few years and upgrading wind parks in the most suitable locations is relevan
Biofilms in the dairy and food industry, particularly those formed by Bacillus subtilis, present significant contamination and food safety challenges. This thesis investigates the impact of stainless steel surface properties, specifically oxide layer formation and surface roughness of polished coupons, on biofilm development. Bacillus subtilis SA 22 (NCA 72-52; DSM 4181) was cultivated using a CDC
Given the increasing share of renewable energy, particularly solar power, there is a growing attention to resource use and disposal challenges associated with Photovoltaic (PV) modules. PV modules consist of multiple layers of materials like silicon, silver, aluminum, glass, and polymers, which makes them difficult to dismantle and recycle. Many recycling methods involve toxic chemicals and create
We construct the meson-baryon chiral Lagrangian at orders two and three. The Lagrangian is constructed in the three-flavour case and with scalar, pseudoscalar, vector and axial-vector external sources included. We discuss the basic ideas of ChPT and the relations that are used to minimise the chiral Lagrangian. The relations that were used are the Bianchi identity, the Cayley-Hamilton relation, th
Syftet med denna studie var att undersöka hur anställda på en skatte- och revisionsbyrå upplever organisatoriska förändringar samt hur organisationens kommunikation kan påverka dessa upplevelser och tilliten till organisationen. Studien genomfördes som en kvalitativ intervjustudie med semistrukturerade intervjuer med nio anställda i olika roller på en skatte- och revisionsbyrå i Sverige. Urvalet vThe purpose of this study was to examine how employees at a tax and audit firm experience organizational changes and how the organization's communication can influence these experiences and trust in the organization. The study was conducted as a qualitative interview study using semi-structured interviews with nine employees in various roles within a tax and audit firm in Sweden. The sample wa
This thesis investigates how Armenia’s security dependence on Russia is discursively constructed and maintained through political texts. Analyzing the 1994 and 2020 ceasefire agreements ending the first and second Karabakh war, alongside 18 official statements from the Russian Ministry of Foreign Affairs (2020–2025), the study argues that these texts function not only as records of geopolitical ev
According to the UN Environment Programme, the construction sector is responsible for 37% of global energy and process-related CO₂ emissions. In Sweden, the latest data from Boverket – the Swedish National Board of Housing, Building and Planning – indicates that this sector accounts for 22.1% of the country's total greenhouse gas emissions. As part of national climate efforts, Fossilfritt Sver
The aim of this study is to explore social workers' experiences with work-related stress and coping, along with their attitudes towards holistic methods as tools for stress management. Since social workers are at high risk for burnout and work-related stress, it is of interest to explore whether a holistic approach can contribute to increasing sustainability among social workers. Through quali
This paper analysed the returns on delta-neutral straddles around macroeconomic announcements. The results for straddles on all macroeconomic events were negative returns across all weighting methods and across the majority of holding periods. Furthermore, the returns for individual macroeconomic data announcements were negative, except for money supply and employment data which showed inconclusiv
Svanödlor (plesiosaurier) är akvatiska reptiler från mesozoikum, runt 251.9 till 66 miljoner år sedan. Fossil från gruppen har beskrivits globalt sedan tidigt 1800-tal, och inkluderar fynd från marina kretaceiska avlagringar i sydligaste Sverige. Här är det fossila arkivet fragmentariskt, och utgörs huvudsakligen av isolerade tänder och kotkroppar. Endast två fragment från kraniet på en svanödla hPlesiosaurs are aquatic reptiles that roamed the world’s oceans during the Mesozoic, some 251.9 to 66 million years ago. Fossils of this group have been recorded globally since the early 19th century, and include finds in the marine Cretaceous of southernmost Sweden. Here, the record of plesiosaurs is fragmentary (a so called ‘scrap fauna’), and mainly made up of isolated teeth and vertebral centr
