As population ageing deepens and rural-urban migration continues, the practice of ageing in place in rural China is facing new housing challenges. Many older people prefer to continue living in familiar villages, but the out-migration of adult children has made family care less stable. Institutional care can provide structured support, but it does not always fit their living habits or emotional ne
Artificial intelligence (AI) is playing an expanding role in infectious disease surveillance and intervention planning by enabling analysis of large-scale health data. One of the key challenges in this area is to characterize transmission within households and to identify factors that influence both infectivity and susceptibility. The present study focuses on the COVID-19 pandemic, which not only
The aim of this thesis is to examine how the public artworks Fossil Composition (1955), Stone Flower (1955) and Tousle (1952), through their bureaucratic municipal processes, reflect the broader ideological ideas of the welfare state, or Folkhemmet, between 1951 and 1956. It also aims to examine what notions of intended municipal identity can be identified through the discourses surrounding the ch
The Greenland Ice Sheet (GrIS) is seeing an accelerated rate of ice melt, which increasingly contributes to global sea-level rise. Studies have reported a growing mass imbalance coinciding with a widespread retreat of the island’s glacial termini. The associated discharge of ice is driven by submarine melting and ice breaking off glacial fronts, a process known as calving. The rate at which calvin
During the third long LHC shutdown (2026-2030), one of the four main experiments at CERN, ALICE, will undergo an extensive upgrade of the Inner Tracking System (ITS3). During this, the three innermost layers of the detector will be replaced by a novel technology, where wafer-scale stitched sensors will be bent into half-cylinder shape and placed one on top of the other, wrapping around the beam pi
Introduktion: Biokol från träpellets analyserades med BET-metoden för att undersöka hur pyrolystemperatur påverkar den specifika ytarean samt hur reproducerbar analysen är. Bakgrund: BET-analys används ofta för att bestämma specifik ytarea hos biokol, men resultaten påverkas starkt av faktorer såsom partikelstorlek, avgasning och materialets heterogenitet. För biokol saknas ofta standardiserade an
Surgical education is traditionally based on apprenticeship and supervised practice, but limited availability of experienced surgeons, restricted access to training cases, and subjective feedback create challenges for efficient surgical training. Solutions utilizing machine learning and computer vision for automating instrument tracking and automated phase recognition have been investigated in lap
Unmanned ground vehicles (UGVs) operating in uneven and unstructured terrain are often limited by fixed sensor mounting, which can reduce mapping quality, situational awareness, and sensor performance when the vehicle body experiences pitch, roll, and vertical motion. This thesis presents the development of a compact four-degree-of-freedom (4-DOF) gimbal prototype for a terrain-mapping module on a
Ett förändrat nederbördsklimat i kombination med ökade trafikbelastningar ställer nya krav på vägkonstruktioners utformning och funktion. Syftet med denna litteraturstudie är att undersöka hur vägkonstruktioner påverkas av kraftig nederbörd och tung belastning, samt att analysera skillnader mellan moderna och äldre konstruktioner avseende lastupptagning och vattenhantering. Vidare behandlas hur daA changing precipitation pattern, characterized by shorter but more intense rainfall events, combined with increasing traffic loads, places new demands on road construction design and performance. The aim of this literature study is to investigate how road structures are affected by heavy rainfall and increased loading, as well as to analyse differences between modern and older road constructions
Material traceability is an important part of industrial manufacturing, especially in systems where quality, reliability, and documentation requirements are high. In many companies, traceability is often assumed to already exist because there are certificates, ERP systems, production documents, and established routines. However, during this study, it became clear that having information available
Energy management in cold logistics is critical for sustainable cold chain transportation. However, conventional reactive temperature control strategies often induce excessive energy consumption and mechanical wear due to rigid air temperature tracking and inability to anticipate system thermal dynamics. Guided by the Design Science Research (DSR) methodology, this study proposes a simulation-base
Particulate matter formation in parenteral protein formulations poses significant safety risks and quality challenges. In the multi-dose injectable products, therapeutic proteins, surfactants, and antimicrobial preservatives are present together, forming a complex system that is more prone to destabilizing interactions. Cyclodextrin (CD) has been proposed as a potential stabilizer, yet its role in
This thesis examines Directive (EU) 2024/2831 on improving working conditions in platform work (PWD) and its implications for both worker protection and regulatory clarity for platform companies within the European Union. The rapid expansion of the platform economy has challenged traditional distinctions between employment and self-employment, where work is organised through digital infrastructure
Bygg- och anläggningsprojekt genererar stora mängder schaktmassor, den årliga mängden som uppstår är cirka 60–200 miljoner ton (Naturvårdsverket, 2024). Schaktmassorna behöver hanteras och omhändertas vilket kan innebära att de återanvänds på den plats de uppstått eller att de transporteras bort för att hanteras på annan plats. Däremot kan massorna vara förorenade vilket ställer till problem, exemConstruction and civil engineering projects generate large amounts of excavated materials, with annual volumes estimated at 60-200 million tons (Naturvårdsverket, 2024). These materials need to be managed and handled, either by being reused at the site of origin or transported to another location for further use. Contamination of the materials can complicate their management, particularly in relat
Introduction: Intumescent fire-retardant (IFR) coatings are widely used to improve fire resistance of wood-based materials by forming an insulating char layer upon heating. Background: The performance of IFR coatings depend on both formulation variables, such as binder, charring agent (CA), blowing agent (BA), acid source as well as environmental exposure which may influence the durability (long
Syfte & mål: Syftet med studien är att undersöka vilka urbana grönstrategier som används i kompakta stadsmiljöer, samt vilka utmaningar, miljömässiga och sociala effekter som finns kopplade till lösningarna. Målet är att skapa en ökad förståelse för hur vegetation kan integreras och bidra till en mer hållbar stadsutveckling. Problemställning: Ökad urbanisering och klimatförändringar har bidAim & goal: The purpose of this study is to investigate which green strategies are used in compact urban environments, as well as what challenges, environmental and social impact are linked to the solutions. The goal is to create an increased understanding of how vegetation can be integrated and contribute to more sustainable urban development. Research questions: Increased urbanization and
This thesis explores the tensions between second-hand clothing consumption enabled by digital platforms such as Vinted and Sellpy as sustainable alternatives to fast fashion. Rather than treating the narratives at face value, we critically examine how service design elements on second-hand digital platforms mirror those of fast fashion. By keeping our focus on Generation Z consumers, we draw on So
This study assesses the suitability of large-scale greening projects in urban areas based on the Berlin Climate Adaptation Act in three study areas in Berlin, namely Mehringplatz, Treptower Straße Nord, and Drontheimer Straße, which were chosen through a selection process using multiple indicators. The reason for this study is to analyse the newly passed Berlin Climate Adaptation Act (KAnGBln), wh
This thesis investigates the quantum Mpemba effect, where an initially hotter system cools down faster than an initially colder one. This was demonstrated in a qubit system coupled to two environments. A thermal state is chosen as the initial state and then left to freely equilibrate. It was shown that the initial thermal state can be chosen in a way to accelerate the resulting relaxation process.
