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

Entreprenadavtal ingås ofta efter upphandling. I utförandeentreprenader betyder det att beställaren har ansvar för att projektera och tillhandahålla entreprenörer ett utförligt förfrågningsunderlag. Detta förfrågningsunderlag avgör omfattningen av kontraktsarbetena och ligger till grund för entreprenörens kalkyl. Vid upphandlingsförfarandet är det viktigt att anbuden är jämförbara. En förutsättninConstruction contracts are often entered into after a procurement process. In construction contracts, this means that the purchaser is responsible for designing and providing the contractor with detailed tender documents. The tender documents form the basis for the contractor's cost estimate and the scope of the construction work. During the procurement process, it is crucial that the submitte

This paper set out to study the motivators in the working culture of the Swedish video game industry. The video game industry is famous for the scandals around its excessive time regime (crunch). The Swedish video game industry is one of the most prominent game producer regions of the world. It operates in Sweden, a country famous for its work-life balance and labour rights. Therefore, this study

During migration birds are exposed to several challenges, one of these are the potential threat of getting oxidative stressed. Oxidative stress can be defined as when free radicals are produced in a vastly amount so antioxidants cannot detoxify them. This is the case at higher metabolic rate such as migratory flight, and probably during hyperphagia at stop-over. The aim of this paper was to invest

This thesis takes its departure in the critical marketing scholarship where the scholars diverge into conflicting perspectives—the Market either being un-politicizing or de-politicizing. The aim of the research, therefore, was to contribute to the critical marketing stream of literature by reconciling these theoretical tensions. We conducted this research with an empirical case of a contemporary c

I en värld där klimathot och resursbrist har växt fram till ett allt större problem på världsledarnas agenda har vikten av hållbar utveckling identifierats som en nyckelfråga i vägen mot en bättre framtid. En metod för detta är industriell symbios, som innebär att olika företag och organisationer gemensamt utnyttjar energi, nyttigheter, material eller service, för att på ett innovativt sätt skapa In a world where climate change and resource scarcity have grown to some of the main issues on the world leaders’ agenda the importance of sustainable development has been identified as a key challenge in the path towards a better future. One method for this is industrial symbiosis, where different entities collaborate over energy, utilities, materials or services to create value and lower cost an

Author: Johanna Lövall Title: ‘ You can get it everywhere’. Parents' views on their ability to influence young people's approach to alcohol and drugs. Supervisor: Teres Hjärpe Assessor: Katarina Jacobsson Background: There is extensive research from different national contexts pointing out parents and some specific parenting approaches as important in preventing or counteracting youth alc

The purpose of this master thesis in practical theology is to investigate the reasons for choices of hymns made by parents baptising their children in the Church of Sweden. From earlier data on baptisms and hymns we do know which hymns are most commonly chosen, but no one to date has interviewed parents on their choices. The method used is semi structured interviews of eleven parents whose childre

This Work is about the fortifications and more specific the gates to cities during the Middle Ages and the renaissance period and how they were designed to project a specific symbol of power. The city gates of Landskrona, Helsingör, Lübeck, and Kristianstad stand as architectural emblems of the Middle Ages and Renaissance, each bearing unique symbolic significance within their respective urban lan

The purpose of this work is to investigate if Miljöbyggnad certification works well for a building company in different regions of Sweden, or if a new or revised working method needs to be developed. To achieve the purpose, the author bases the study from a couple of interviews. The conclusion of the study showed that the Miljöbyggnad certification is rarely required at the Swedish building comp

When constructing roads, it often happens that the contractor have trouble following the documentation intended for the project. When the contractor is unable to follow the documents and instead need new instructions, there is always changed, added or outgoing work. Sometimes this could mean that it is impossible to stay within the road area, for example, to accommodate the slopes, or more land ne

Surfaces subjected to rolling and sliding contacts may suffer from contact fatigue. The cam and roller follower mechanism is a typical rolling and sliding contact. This thesis deals with the running in aspects to avoid high stress variation that leads to fatigue wear and the aspect of what happens to indentation damages that occurs on the surface if there are any particles in the lubricant. The pa

Lokshtanov, Marx, and Saurabh SODA 2011 proved that there is no (k-epsilon)^pw(G)poly(n) time algorithm for deciding if an n-vertex graph G with pathwidth pw admits a proper vertex coloring with k colors unless the Strong Exponential Time Hypothesis (SETH) is false, for any constant epsilon>0. We show here that nevertheless, when k>lfloor Delta/2 rfloor + 1, where Delta is the maximum degree in th

BACKGROUND: Maternal smoking during pregnancy has repeatedly been associated with decreased sperm counts in sons. Nevertheless, our team recently detected a lower total sperm count in the sons of smoking fathers as compared to sons of non-smoking fathers. Since paternal and maternal tobacco smoking often coincide, it is difficult to discriminate whether effects are mediated paternally or maternall

Background: People with a disability affecting their mobility are more likely to be overweight or obese than those without a mobility disability. The guidelines on how to prevent and treat overweight/obese adults in the general population have not been adapted to the needs of people with a mobility disability. A reasonable useful first step in the process of adapting such guidelines is to conduct

This report describes how the work has been conducted in the project “A National Strategy for Standardisation of Digital Information Management within the BuiltEnvironment” (further on denoted NSS). This report describes the project background, aim, objective, methodology, schedule, organisation, and identified areas and processes that have been the basis for the development of the initial three-y

Popular Abstract in Swedish Datorgenererade bilder är en viktig del av underhållningsindustrin, som bland annat innefattar spel- och filmindustrin. För att kunna skapa avancerade specialeffekter i filmer samt stora och detaljerade spelvärldar krävs datorprogram som utnyttjar beräkningskraften i dagens datorer på ett effektivt sätt. Bättre och snabbare datorprogram leder ofta till nya användaruppleComputer generated imagery is vital to the entertainment industry in the production of games and films, for example. It is also increasingly important for visualization in design, architecture, engineering, and medicine, to name a few. Improvements to rendering techniques come from a combination of improved algorithms and more powerful hardware. Typically, hardware developments introduce new chall
