This thesis investigates the focusing performance and robustness of auto-focusing Airy beams in near-field wireless communication scenarios. Through a combination of simulations using MATLAB (Matrix Laboratory, a numerical computing environment) and full-wave electromagnetic simulations in FEKO (Feldberechnung für Körper mit beliebiger Oberfläche, an electromagnetic solver developed by Altair), th
This master thesis presents the development of a vision-based feedback control system for automating sample placement in a virtual neutron beam emulated using a laser. The thesis was carried out on behalf of the European Spallation Source (ESS) to investigate the feasibility, possibilities and limitations of using a robotic automation system for sample alignment. Due to the radioactive research en
Cell type deconvolution - the computational estimation of cellular composition in bulk tissue samples - is a valuable tool in cancer research for understanding immune infiltration and tissue heterogeneity. Most deconvolution algorithms infer the composition of cell types in bulk samples by modeling the observed expression data as a linear combination of reference expression profiles from each cell
Denna uppsats undersöker hur det tyska partiet Alternativ für Deutschland tillskriver nationell identitet i sitt språkbruk utifrån kapitel 12 Kultur und mediapolitk från deras valprogram inför valet 2025. från. Arbetet utgår från metoden textanalys där verktyget What s the problem represented to be av Carol Bacchi (2009) appliceras i analysen kombinerat med teoretisk forskning kring populism enlig
Bakgrund: Preoperativ ångest är vanligt förekommande inför kirurgiska ingrepp och anestesi. Ångest kan bottna i brist på information, oro för kirurgi/anestesi, komplikationer eller rädslan att dö. Hög preoperativ ångest är kopplad till negativa effekter, såsom: ökat behov av anestesimedel, instabilare vitalparametrar, mer postoperativ smärta och illamående, samt sämre återhämtning och sårläkning. Background: Preoperative anxiety is commonly experienced prior to surgical procedures and anesthesia. This anxiety may stem from a lack of information, concerns about the surgery or anesthesia, potential complications, or the fear of death. High levels of preoperative anxiety are associated with negative outcomes, such as increased need for anesthetic agents, less stable vital signs, more postoper
This study aims to create a greater understanding of how public librarians in Sweden perceive target groups of easy-to-read books for adults and how they work to mediate those books to the different groups. To investigate these questions, I have conducted interviews with seven librarians at four public libraries in Sweden and analysed the results using the classification theory of Bowker and Star
Household expenditure patterns in Ukraine were explored with a focus on clustering techniques to uncover socioeconomic insights and inform policy interventions. Using an officially published Household Income Survey dataset for 2021, the research applies advanced machine learning models, including k-means, DBSCAN, and PCA, to analyze spending habits and identify household profiles with distinct exp
Title: TAKT Production System for Assembly (including material supply) of Crushing Equipment at Sandvik Problem formulation: A major part of Sandvik’s production system is driven by forecasting. While this method provides a structured approach for anticipating future demand, it introduces several operational challenges that disrupt the capacity of the equipment assembly line and flexibility. Thes
This thesis critically examines the Swedish ‘Security Zones’ legislation, the associated governmental discourse on organised criminality, and their implications for equality and racial justice. Through a critical discourse analysis, the thesis illustrates how the extended discretion afforded through the legislation facilitates law enforcement’s capacity for racial profiling and discrimination. It
Problem Statement: Sandvik Rock Processing is in the need for a classification tool, which can help them improve their inventory management. Currently, there are problems with inefficiencies with deficit as well as excess in inventory. The new classification shall the basis for the differentiation of service levels and facilitate a shared view on items’ importance. Purpose: The purpose of this th
This thesis investigates the performance and feasibility of passive and active analog frequency compensation filters for audio signal processing in a distributed speaker system. One passive and one active circuit topology were investigated more thoroughly and then the active filter was realized on a PCB and evaluated with electrical, thermal and acoustic measurements. The work also resulted in tw
While Swedish politics actively develops crime prevention strategies, particularly targeting gang-related criminality, the role of schools in these strategies raises critical concerns. This thesis focuses on the legal obligation of principals to inform the police, which may help prevent, hinder, or detect criminal activity. Schools are increasingly positioned as arenas for policing and prevention,
Klimatförbättrad betong erbjuder en av byggsektorns mest tillgängliga vägar till minskade utsläpp. Utnyttjandet begränsas dock i praktiken mer av produktionsförhållanden och tradition än av materialet i sig. Betongproduktion står för en betydande del av de globala koldioxidutsläppen. Cement, en av de huvudsakliga komponenterna i betong, går delvis att ersätta med tillsatsmaterial som mald granuleCement production accounts for a significant share of global carbon dioxide emissions, which has made the development of climate-improved concrete a central concern for the construction industry. Replacing part of the cement with supplementary cementitious materials reduces the climate impact, but slows the development of early-age strength, an effect particularly pronounced at low temperatures.
This thesis explores the visual and cultural representation of worldbuilding in fantasy genre video game trailers. The focus is to find out to what extent video game trailers in the fantasy genre utilise visual tropes and cultural representations to establish an identity as fantasy video games. It is well established that game developers look for inspiration in the real world when creating new one

58 million children around the world lack access to education, and another 250 million children only have access to unfit schools with poor quality. Through interviews with volunteer teachers and social workers conducted during three weeks of fieldwork in Tehran, this study maps the educational situation of undocumented Afghan migrant children living in Iran, in order to understand the role of edu
The purpose of this thesis was to explore the Swedish pharmacy market and the potential influence different levels of legal pressure have on sustainability reporting. Interviews with pharmacy representatives and document analysis of sustainability reports and policies were combined, grounded in a constructivist perspective to analyze incentives for sustainability reporting. The data collected was
The aim of this study was to analyze how municipalities can promote circular economy (CE) in the public procurement, focusing on procurement of computers. Furthermore, the aim was to identify opportunities and barriers for the integration of the CE within municipal procurement and analyze where the market is heading. The methods used in this study consisted of a literature study and semi-structure
Denna uppsats undersöker översättning och lokalisering av dataspel för den svenska marknaden. Studien utförs mot bakgrund av att engelskan har en mycket stark ställning i Sverige och inom dataspelsgenren. Uppsatsen bygger på en korpus som består av 104 dataspel som har sålts i Sverige åren 2009-2015, vilka har hämtats från försäljningsstatistik som finns tillgänglig från organisationen Dataspelsbr
Policy Coherence for Development is a concept, framework and tool for achieving a more effective and organized global development agenda. Under the principles of Policy Coherence for Development (PCD), the potential conflicts of objectives between various policy areas should be identified and preferably resolved – with developmental objectives in mind. The PCD has named some policy areas as “expec
