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
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
This study aimed to examine how interrogation techniques in the form of alpha and omega strategies, as well as a rapport-based approach by the interviewer, were related to engagement and information disclosure in intelligence interviews. The study was conducted through observation and coding of 66 interviews involving a total of 19 interviewees and 6 interviewers in a training-based and realistica
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
This thesis examines how tourism-related retail change reshapes retail place in Swedish city centres. Rather than approaching tourism and retail only through expenditure, shopping behaviour, or destination attractiveness, the study analyses retail place as a lived social, spatial, material, and symbolic environment. The aim is to understand how tourism contributes to changes in city-centre retail,
När ett nedslag gräver upp och modifierar Mars yta, genom att medföra material från djupare delar till ytan, öppnar det fönster ner till äldre geologi. Att försöka förstå ytegenskaper på Mars och hur källmaterialet beter sig vid ett nedslag kräver en metod från flera perspektiv. Tidigare forskning har främst fokuserat på ejecta och ejektamorfologi som en indikator på ytegenskaper. Däremot kan ävenWhen an impact excavates and modifies the Martian surface, by bringing deeper lying material to the surface, it opens a window into past geology. Trying to understand surface properties on Mars and how target material behaves during impact requires a multi-view approach. Previous research has focused mainly on ejecta emplacement and morphologies as a proxy for surface properties. However, interior
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
Följande uppsats har undersökt sambandet mellan subjektivt välbefinnande och fyra centrala aspekter av studentlivet i Lund: Socialt stöd, Self-efficacy, engagemang samt alkoholvanor och attityd till alkohol. Bakgrunden till studien var forskning kring en minskning i studenters välbefinnande samt den unika sociala kontexten i Lunds studentliv, starkt karakteriserad av sociala nätverk, engagemang ocThe following study has examined the relationship between subjective well-being and four key aspects of the student life in Lund: Social support, Self-efficacy, engagement in student organizations and alcohol consumption & attitude. The study was motivated by previous research regarding students mental well-being decreasing in the past years as well as the unique social context of Lund’s stude
Denna uppsats är författad av Alice Dahlberg, Alva Wisti, Julia Hamma och Tilda Åhman Rosvall i Medie- och kommunikationsvetenskap vid Institutionen för kommunikation och medier, Lunds universitet. Studien undersöker hur kristen tro representeras och ges mening genom Kanal 10:s digitala medieinnehåll i relation till ett sekulariserat svenskt samhälle. Det finns begränsad forskning om hur kristna m
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
