Transformatordiagnostik genom dissolverad gasanalys
The transformer is one of the most common and most important electric machines for power companies. Cost of investment and the economic worth of a transformer are counted in millions of SEK. Because of that, proper maintenance actions that may lead to longer technical life time should be the aim in all situations.The aim with the report was to perform transformer diagnosis by dissolved gas analysis on Umeå Energi AB´s power transformers and a risk assessment. The report should also contribute to longer life time for the transformers.Oil samples were taken from each transformer two times. The first sample in summer 2013 and the second in April 2014.
"The Machine Made Me Do It!" : An Exploration of Ascribing Agency and Responsibility to Decision Support Systems
Are agency and responsibility solely ascribable to humans? The advent of artificial intelligence (AI), including the development of so-called ?affective computing,? appears to be chipping away at the traditional building blocks of moral agency and responsibility. Spurred by the realization that fully autonomous, self-aware, even rational and emotionally-intelligent computer systems may emerge in the future, professionals in engineering and computer science have historically been the most vocal to warn of the ways in which such systems may alter our understanding of computer ethics. Despite the increasing attention of many philosophers and ethicists to the development of AI, there continues to exist a fair amount of conceptual muddiness on the conditions for assigning agency and responsibility to such systems, from both an ethical and a legal perspective. Moral and legal philosophies may overlap to a high degree, but are neither interchangeable nor identical.
Att leva med stomi. En litteraturstudie om hur stomiopererade personer upplever sin nya livssituation och den omvårdnaden de får av sjuksköterskan
The purpose of this study was to find knowledge about ostomy patients experience with a focus on overall life situation and the care they receive from the nurse. The method used was a systematic literature review according to Polit, Beck & Hungler. Six scientific research reports have been used as foundation of the result in this study. The articles have been reviewed according to Antonovsky's Sense of Coherence (SOC).The result shows that experiences of having ostomy are individual. Adapting to their new life situation varies depending on the reason for having an ostomy.

Bestyrkande av hållbarhetsredovisning : kostnad & nytta
Sustainability reports have during the last decade had a strong development. Both in terms of establishing a sustainability assurance, in its form, and get it assured together with standards, principles and regulations which organisations and accountants have utilized. The growth of sustainability reports and the choice of getting them assured have in particular favoured the accounting business. Due to this result, some critics have voiced that assuring a sustainability report gain accounting firms more than it gains the actual organisation. Other say that it is necessary in order to increase the credibility and the eligibility of the report, while it also has become a requirement from stakeholders.
Religion och vetenskap : En studie om tematiken religion och vetenskap samt dess gränsländer i gymnasieläromedel
The following essay aims to determine what textbooks and teaching media educators in the county of Västerbotten use when teaching the relation between religion and science. Based on educational science theory and through analyzes of factual texts, the teaching materials was examined to determine how much focus they put on the thematic of religion and science. The result shows how the different teaching materials affect this thematic differently. The main conclusion is therefore that students in Sweden could, depending on the teaching materials used in their education, be taught by different standards to reach the same requirements..
Att styra säkerhet med siffror : En essä om (att se) gränser
Work, especially that in complex, dynamic workplaces, often requires subtle, local judgment with regard to timing of subtasks, relevance, importance, prioritization and so forth. Still, people in Nuclear Industry seem to think safety results from people just following procedures. In the wake of failure it can be tempting to introduce new procedures and an even stricter "rule following culture". None, or at least very little, attention is given to tacit knowledge and individual skills. I am aiming to highlight the inadequacy of putting too much trust in formalization and that reporting and trending of events will contribute to increased learning, an increased nuclear safety and an efficient operational experience.
Kognitionsforskning i djurhållningen: grisars kognition och dess tillämpning vid slaktsvinshållning
Pigs are often mentioned as relatively intelligent animals when compared to other nonhuman species. Despite this knowledge, the vast majority of pigs are kept under conditions that lack opportunities to satisfy their cognitive needs. Therefore, a need to evaluate the present scientific studies about pig cognition was acknowledged, in order to evaluate to what extent the knowledge is applied in the husbandry of finishing pigs. If a considerable lack of application was determined, suggestions about how to use the obtained information to improve pig welfare were also to be made.
A synthesis of the present literature was made, and it could be concluded that a considerable amount of studies had been carried out in the present area. The pigs of today appear to have the same behavioural and cognitive needs as their ancestor, the wild boar.

Forensiska Undersökningar av Molntjänster
Användning av molntjänster har gjort forensiska undersökningar mer komplicerade. Däremot finns det goda förutsättningar om molnleverantörerna skapar tjänster för att få ut all information. Det skulle göra det enklare och mer tillförlitligt.Informationen som ska tas ut från molntjänsterna är svår att få ut på ett korrekt sätt. Undersökningen görs inte på en skrivskyddad kopia, utan i en miljö som riskerar att förändras. Det är då möjligt att ändringar görs under tiden datan hämtas ut, vilket inte alltid syns.
Portrayal of animal communication in wildlife documentary
Many people turn to documentaries for knowledge about animals, but do documentaries give us a truthful portrayal of animals and their behavior? This study looks at how the communication behavior of the portrayed animals is depicted in three episodes of The Life of Mammals. These episodes were observed after which the contents were compared to scientific literature on the same topics. The results show that quite little communication is actually shown in the episodes about plant predators and meat eaters and relatively much of it is shown in the episode named Social Climbers, involving primates. The matching literature suggests that based on the narrative and the accompanying footage, the viewer is getting a realistic picture, with the exception of a few questionable cases..
Varför Klass? Att studera ojämlikhet ur ett statsvetenskapligt perspektiv
This thesis contains a wider discussion on the analytical framework of classstudies in political science. The purpose is to put class into the light of a usefulmethodological and theoretical tool when it comes to studies on inequality and political,as well as scientific approaches and explanations to why people have awide range of differences in how they pursue their lives. It is my ambition to discusshow class relations can be theorized and explained within a given context, aswell as in society as a whole. I see the complexity of this field as a resource to enhancethe epistemological as well as the empirical discussions within the politicalscience scholars..
Bibliotekariers syn på Open access : Enkätundersökning bland bibliotek med inriktning teknik, naturvetenskap, medicin och farmaci
Open access to scientific literature on Internet is a concept which is supposed to change librarians' work. The aim of the thesis was to examine librarians' perception of Open access. A questionnaire survey was conducted among librarians at libraries with specialisation in technique, natural sciences, medicine and pharmacy in Sweden. Even though Open access can be regarded as an alarming for librarians' work, the results of the survey showed that the future of the librarians' profession can be positive if they flexibly adopt their work routines according to changes in publication forms and library users' needs..
