Non-terrestrial networks (NTNs) are expected to become an important component of future sixth-generation (6G) wireless systems by extending broadband coverage to remote, maritime, aerial, and underserved areas. Among different NTN platforms, low Earth orbit (LEO) satellite constellations are particularly attractive due to their lower propagation delay compared with geostationary systems. However,
Dagvatten kan transportera föroreningar till recipienter, vilka kan vara skadliga för både djur, natur och människor. Dessa föroreningar inkluderar bland annat metaller och näringsämnen. En betydande källa till tungmetaller är vägtrafikrelaterad, då bland annat slitage från bromsar och däck samt galvaniserade metallstrukturer ger upphov till föroreningar. Föroreningar med fraktioner som är min
This thesis investigates the quantum dynamics of a three-level laser system described by the Scovil and Schulz--DuBois model with emphasis on the emergence of classical laser behaviour. In particular we study the time evolution from an initially coherent quantum field. We compare closed Jaynes--Cummings dynamics with open Lindblad dissipator dynamics including hot and cold Markovian reservoirs, wh
Den svenska marknaden för abonnemangsbaserade streamingtjänster (SVOD) har under de senaste åren präglats av ökad konkurrens och ett växande antal aktörer. I takt med att streamingtjänster blivit en central del av det svenska medielandskapet har förståelsen för varför användare stannar kvar hos specifika tjänster blivit allt viktigare, särskilt eftersom affärsmodellen bygger på långsiktig kundrete
Global plastic production exceeds 400 million tons annually, with polyolefins accounting for nearly half. Their highly stable hydrocarbon backbone makes them highly resistant to degradation, leading to environmental accumulation and significant contributions to plastic pollution. Conventional recycling methods are insufficient to address these challenges, highlighting the need for more sustainable
The most prevalent method of peptide production, solid-phase peptide synthesis (SPPS), generates large amounts of hazardous solvent waste, typically DMF. This waste, combined with the use of the insidious PFAS chemical TFA for side chain PG removal and final resin cleavage, has prompted research into PFAS-free and aqueous solid-phase peptide synthesis (ASPPS) of linear peptides. With the growth of
The purpose of this study is to develop an in-depth understanding of middle managers’ sensemaking processes during planned organizational change by examining their use of metaphors, and to analyze how these metaphors influence their role in between strategic intent and organizational practice. Adhering to the interpretive research tradition, the study follows an abductive, qualitative single-case
In the collective model of the atomic nucleus, oscillations in the quadrupole deformation naturally arise; a type of these dynamic shape fluctuations are known as γ-vibrations. However, features attributed to these vibrational modes may instead arise from static triaxiality through configuration mixing. This thesis explores a possible way to avoid this ambiguity. Whilst single phonon γ-vibrations
In the current day, some medical instruments rely on older authentication methods for staff and service workers which are outdated and pose a security risk. This project aims to increase security measures to protect sensitive data as well as impose stronger authentication protocols. To create the architecture necessary, an analysis is made. The analysis covers potential threats to the system as we
Hybridarbete har blivit en alltmer etablerad arbetsform i arbetslivet och kan innebära ökad flexibilitet och autonomi. Samtidigt kan arbetsformen bidra till att gränsen mellan arbete och privatliv blir mer otydlig, särskilt när arbetet inte längre är bundet till en specifik fysisk arbetsplats. Möjligheten att arbeta på distans kan även bidra till att anställda arbetar trots sjukdom vilket kan påve
Social work involves meeting people in difficult life situations, which can lead to secondary traumatization and affect both well-being and professional practice. Despite previous research, there is limited knowledge about how social workers experience these effects in their daily work and decision-making. The study explores how professionals within social services experience secondary traumatizat
This study aimed to examine how professionals within the probation services in Sweden work with recidivism prevention, and their personal descriptions of the important components within the work. The study also aimed to determine if there are any differences in the recidivism prevention about the client's gender. The approach has been carried out through a qualitative study. The qualitative st
This study analyzes the feasibility of implementing a Control Tower (CT) within Lindab’s supply chain in order to improve its visibility, coordination, and efficiency. Lindab operates within a highly complex and decentralized logistics network, with multiple production plants distributed across a large part of Europe. This structure generates significant logistics inefficiencies, especially relate
The consequences of climate change include an increased risk of landslides, erosion and flooding of buildings in cities. Swedish municipalities have a planning monopoly, which means they have autonomy over urban planning and consequently a responsibility to climate-adapt their cities. It is not enough to focus solely on reducing emissions, climate adaptation measures must also be implemented. To m
Child welfare investigations within social services are conducted in an organizational context characterized by high demands, limited resources, and growing administrative responsibilities. This study aims to highlight social workers’ experiences of organizational conditions in child welfare investigations and how these conditions are managed in practice. Semi-structured interviews were conducted
Supramolecular hydrogels have attracted increasing attention in drug delivery, tissue engineering, and injectable biomaterials because of their high water content, good biocompatibility, and dynamic network structures. Cyclodextrin-based supramolecular systems can form network structures through host–guest interactions. These systems usually require mild cross-linking conditions and allow flexible
Many consumers say they want to shop more sustainably. But most retail websites do not make that easy. Walk through a typical online furniture store, and you will find sustainability information buried in product specifications or tucked away behind a separate filter tab. This happens right when you are already trying to balance price, looks, and whether the thing will actually fit in your living
För att underhålla järnvägar på rätt sätt behöver arbetare kunna nå spåret snabbt och enkelt. Detta examensarbete undersöker hur tillgången till järnvägsanläggningar fungerar idag och vilken skillnad servicevägar gör för underhållsarbetet. Studien bygger på intervjuer med åtta personer från Trafikverket och järnvägsunderhållsföretag, data från felrapporteringssystemet Ofelia för åren 2000–2023 samTo maintain railways properly workers need to be able to reach the track quickly and easily. This thesis looks at how access to railway facilities works today and what difference maintenance access roads make for maintenance work. The study is based on interviews with eight people from Trafikverket and railway maintenance companies, data from the fault reporting system Ofelia covering the years 20
Målet med detta projekt är att skapa en produkt som utforskar kombinationen av träning och förvaring, samt hur dessa funktioner skulle kunna integreras i en möbel. Modularitet, anpassningsförmåga och estetik är nyckelord i processen för att skapa en möbel anpassad för hemmiljö.
This study aims to investigate the role of relationship building in social work and the strategies social workers use to create and maintain positive and sustainable relationships with clients. The study is based on an abductive approach and applies a qualitative methodology. Empirical data were collected through two focus groups and three semi-structured interviews with professional social worker
