Studien syftar till att öka kunskapen om riskerna som kan påverka tidsåtgången för underhållsarbete inom järnvägen, särskilt vid byte av fast korsningsparti i spårväxlar. Den tid som vanligtvis tillges vid underhåll ger inget utrymme för att oväntade händelser uppstår, därför är det av stor vikt att underhållet utförs effektivt för att slutföras inom tidsramen. Riskhanteringar utgörs av följande mThe study aims to increase knowledge about the risks that can affect the time required for maintenance work on railways, particularly when replacing fixed crossing sections in switches. The time allocated for maintenance usually does not allow for unexpected events, so it is crucial that maintenance is carried out efficiently to be completed within the timeframe. Risk management comprises the foll

The purpose of this study was to compare the food security and dietary diversity status of Bangladeshi immigrants living in Sweden to their position in Bangladesh. Structured surveys were used to collect data from 15 Bangladeshi immigrants, which included demographic information as well as indices of food security and dietary diversity. Food security was assessed using the Household Food Insecurit

Att påverkas av andra är något för oss så naturligt att vi sällan tänker på hur ofta det händer. En annan kropps närvaro kan ge oss energi lika väl som ta den ifrån oss. Den kan få oss att vilja komma närmare eller längre ifrån. Detta samspel är inte unikt för oss människor, utan kan även ses på himlavalvet. På universums dansgolv finner vi par av alla dess slag. Särskilt mystiska är kanske de svaGalactic nuclei contain super-massive black holes (SMBHs), nuclear stellar clusters (NSCs), or both. In the NSC, intermediate-mass black holes (IMBHs) are likely to reside and form highly eccentric binaries. Over time, the orbit of a binary could harden via interaction with surrounding low-mass stars. Eventually, it would be possible for the IMBHs to, via the emission of gravitational waves (GWs),

The deep-seated role of private vehicles in our lifestyles limits the pursuit of sustainable urban development from an economic, social, and environmental standpoint. As such, this qualitative study aims to identify and explain the determinants behind the car phenomenon. Interviews are performed with non-low-income car owners in Milan and Stockholm commuting zones. The two areas depict different a

This thesis investigates if China is a socialist economy or not. The topic, which has triggered many leading scholars, is highly interesting since institutions are pivotal to understanding a country’s economic performance. Previous studies have neglected the classic socialist literature, giving ambiguous interpretations of what is socialism. This thesis fills that gap through a multicriteria appro

Syftet med denna rapport är att utvärdera möjligheten att använda Virtuell Verklighet (VR) som ett medium för användbarhetstestning. Användbarhetstestning är en viktig del av alla iterativa utvecklingsprocesser. Vanligtvis utförs testerna i en laboratoriemiljö utanför produkternas naturliga miljö. Genom att använda VR kan dock användare uppleva testmiljön på ett mer realistiskt sätt. Studien genoThis thesis aims to evaluate the feasibility of using virtual reality as a medium for usability testing. Usability testing has long been an important part of any iterative development process. Most usability testing is, however, done in a lab setting, outside the product's natural environment. Virtual Reality (VR) on the other hand can engross a user in any environment. This thesis was done i

Ända sedan tidernas begynnelse har människor funderat på frågor kring den värld vi lever i och dess ursprung. Förklaringarna har varit många, olika och har ofta varit förknippade med religiösa trosuppfattningar. Idag är den rådande vetenskapliga konsensusen att vårt universum skapades för cirka 14 miljarder år sedan i det så kallade Big Bang, eller 'Den Stora Smällen' på svenska. Enligt deIn this report, the elliptic flow in high centrality Pb-Pb collisions is calculated using two particle correlations $v_2\{2\}$ but without any imposed separation in η with data taken from the ALICE experiment at CERN in 2015. Instead, measurements of the same correlations in proton-proton collisions is used as a background to account for non-flow effects and data is correlated between the time pro

The current paper aims to explore the psychometric properties of two public domain cognitive ability scales, Cog15 and ICAR16, and investigate how well they each capture the g-factor in a Swedish sample (N = 428). The motivation for choosing these aims is that public domain, free, and easily accessible intelligence tests are needed for measuring the g-factor. Principal components analysis (PCA), c

The aim of this study was to gain an understanding of how gender was used and expressed through burial customs in the South Scandinavian mesolithic. This topic was chosen to further explore gender aspects during the mesolithic through different perspectives on the burial to complement previous research. For this purpose 110 graves from Sweden and Denmark were examined and 48 of them were deemed ap

The Jute-ICARE initiative by the Government of India aims to address climate change's impact and improve jute farmers' livelihoods. This study investigates the challenges and opportunities for jute farmers in adopting the scheme's technologies using the DPSIR framework and the social learning theory. Inadequate information dissemination to farmers and differing perspectives between pol

The purpose is to investigate retail investors’ growing influence in shaping corporate investment policies. It further seeks to understand whether firms cater to retail investor sentiment. We employ a multiple linear regression model of a strongly-balanced panel data set, incorporating fixed effects and clustered standard errors. We construct a Financial and Economic Attitudes Revealed by Search (

In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. However, the accuracy and results of industrialised pipelines to derive stellar parameters and abundances ha

Frågeställning: Vilka förpackningsattribut

In the small Danish nature park of Jægersborg Dyrehave, there live over two thousand deer. During their lives, they become encounters for visitors, managers of nature, targets to be culled, meat to be eaten, and more. In this thesis, I explore what it means to be deer in Dyrehaven. By applying a posthumanist iteration of performativity, I argue that we need to consider ‘deering’ as a verb, an intr

There is a need to identify leverage points for a broader cultural transformation that addresses the root causes of the nature-climate emergency. Music and art festivals are creative free spaces outside the everyday workings of society that have the potential to plant the seeds of a holistic, sustainable future. I combine prefiguration and the three spheres of transformation in a framework to inve

This thesis studies the awareness of the Swedish financial sector on biodiversity and nature-related information by analyzing the external communication reports of firms listed on the NasdaqOMX stock exchange in Stockholm. The reports are analyzed with the help of a checklist and a Python script. The checklist covers key topics, including the importance of biodiversity in sustainable development,

Blue straggler stars (BSSs) are exotic stellar objects that appear to be younger than the age of the population they come from suggests. They are observed as the extension of the main sequence stars, beyond the turn-off point. They are present in all types of stellar populations, such as open clusters, globular clusters, dwarf galaxies, and even in the open field. It is believed that they form mai

Detta examensarbete ämnar att undersöka integration av tre olika teknologier till en havsbaserad vindkraftspark, om det är ekonomiskt gynnsamt samt hur kraftfluktuationerna till elnätet påverkas. Genom att kombinera olika förnybara kraftsystem kan man minska variabiliteten och kostnaderna kopplade till installation och drift av systemen. Även fast investeringar i annan förnybar energi utöver vindkThe high penetration of wind power is increasing the intermittency and power variability into the existing power grid. This is forcing industries to look for optimal configurations in order to improve their systems performance and minimize these effects from the power production method. Studies show that there are different ways of reducing the power variability and therefore stabilize the energy
