Fennoscandian permafrost peatlands and palsa mires have exhibited pronounced thawing over recent decades, resulting in increased active layer thickness (ALT) and thermokarst formation. Consequently, open water areas have expanded in the well-studied palsa mire Stordalen, located in northernmost Sweden. However, long-term quantifications of open water dynamics remain limited and the relationship be
The continued scaling of complementary metal-oxide semiconductor (CMOS) technology has fundamentally altered the relationship between register-transfer level (RTL) design and physical implementation in application-specific integrated circuits. The traditional sequential treatment of these two activities is no longer adequate for meeting the power, performance, and area targets of modern system-on-
This thesis investigates the possibility of dark matter arising from a confining dark SU(N) Yang-Mills sector with N=3,4,5. First, standard results from the established single-scalar-glueball framework are reviewed and numerically reproduced in order to follow the cosmological evolution through the confinement phase transition and extract the relic abundance. The results reproduce the expected qua
Grated cheese is a convenient and ready-to-use food product. However, due to its increased surface area, grated cheese is susceptible to spoilage. This master’s thesis aimed to improve the understanding of growth patterns of spoilage microorganisms in relation to intrinsic factors in both grated mozzarella and grated hard cheese. Cultivation of yeast and lactic acid bacteria, using pour plating- a
This thesis project, Spatial Practices of Ageing Well in Place, explores how collaborative housing can be spatially reinterpreted to support ageing in place in low-income, kinship-based rural villages in China. Based on the fieldwork in Quanfang Village, the project proposes a small-scale housing prototype that responds to the weakening of family-based care. Rather than applying collaborative hous
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
