Konvertering från luft till vätskekylning av elektronik

A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

?Du kan göra skillnad i människors liv utan att ha en aning om det? : En kvalitativ studie om några socialsekreterares syn på suicidalitet

During 2010, 1446 people committed suicide in Sweden. Research shows that groups that are less favored in society have an increased risk of suicide. Social services often encounter groups of people that have a high risk of suicide, for instance welfare recipients or substance abusers. The purpose of this study was to shed light on how social workers talk about suicide and how this might affect interactions with suicidal clients. The study is based on qualitative interviews with five social workers in Stockholm.

Det förlovade folkhemmet? : en studie av svensk civilreligion speglat i socialdemokraternas retorik 1928 - 2008

The aim of this paper is to apply Robert N. Bellahs theory of civil religion, within a Swedish societal context. Bellahs theory was designed in, and influenced by American culture. Therefore, the ?translation? of Bellahs theory does not come without problems.

Mobbning - ett groupthink-fenomen? : En gruppsykologisk fördjupning av mobbning

The purpose of this essay was to examine and shed light on bullying as a groupprocess, a social phenomenon taking place in a school setting, to increase the understanding of the phenomenon. A theoretical overview of the litterature on bullying was made to investigate bullying and to give the reader a view of the researchfield. A total of 77 articles was studied. With the intention of studying bullying from a groupsychology perspective a metaanalysis was performed discussing groupphenomenon such as rolebehavior, responsibility, cohesiveness and norms in comparison to bullying episodes.Stemming from this analysis the question whether bullying can be view as a response to groupthink emerged. This question also constituted the secondary aim of this thesis.

?TRO OCH TVIVEL? En studie om kristen tro i ett en g?ng sekul?rt men numera postsekul?rt Sverige

This thesis explores how participants and leaders in ?Alpha?, an introductory course to the Christian faith, relate to and practice faith in Sweden. Sweden has often been viewed as a secular country where religion has been seen as irrational, outdated, and as something that belongs to the other but not to the self. Through the eyes of Swedish Christian practitioners, this study explores what kind of relationship my informants have to Christian faith and God while also exploring how living in a secular or post-secular context affects their way of believing and interpreting God and the stories written in the Bible. Furthermore, understanding of the Bible is viewed in the light of the concepts ?mythos? and ?logos? which highlights where Western explanatory models fail to explain and understand mythological stories.

Sveriges mest monumentala målning? : Mediala praktikers betydelse för formeringen av kulturarv. En undersökning av 1987 års debatt om Carl Larssons Midvinterblot

This essay examines the debate that arose in connection to the sale of Carl Larsson?s monumental painting Midvinterblot in 1987. My main purpose is to examine which meanings the debaters ascribed Midvinterblot and in which way the debate influenced the paintings significance as cultural heritage. I will therefore argue that the debate initiated a renegotitation of the paintings meaning as cultural heritage. In the debate the debaters emphasized the National Museum?s responsibility over cultural heritage, Midvinterblots aestethic, the paintings economic value and its national implications.

Fibulas vikingaby på Åland - En undersökning om hur man kan förbättra, utveckla och tillföra nya idéer till en nutida vikingaby

In this essay I try to look into how to bring a new concept to an already established Viking village and how to develop the existing one. This essay also sheds light on some negative sides that a Viking village can experience in their activity.I have interviewed responsible persons at three different Viking villages: Foteviken Museum and Viking Reserve, Fornföreningen Fibulas Viking village and VikingaTider. I have also examined different kinds of literature dealing with my chosen Viking villages.I came to the conclusion that I should have chosen an other Viking village than VikingaTider because a lot of VikingaTiders activity hasn´t really started yet. On the other hand it has been interesting to see how they are trying to start the activity and which their plans are. I could have chosen an other already established Viking village to get a more varied material.There are a lot of things that Fibula can do to improve, develop and bring new aspects to their concept.I have found both advantages and disadvantages with the different Viking villages activity and strategi.

Holografisk Video

Detta examensarbete utgår ifrån en artikel i vilken en metod för att skapa holografisk video beskrivs. Syftet med arbetet är att återskapa denna metod. Metoden bygger på projicering av hologram med hjälp av delar från en projektor, en laser och några linser.Först görs en litteraturstudie för att få förståelse över hur metoden fungerar. Här behandlas hur ögat ser djup och vilka olika typer av displayer det finns för att återge tredimensionella holografiska bilder. Vidare beskrivs skillnaden mellan optisk och datorgenererad holografi.

The Green Evolution of the Car Industry

This Master Thesis covers the concept of Green Cars. The background to the research area is the high and rapidly growing number of cars, which together with other factors ad to the pollution of the environment. Under the Kyoto agreement the signing members agreed to lower the emissions of green house gases, further on the EU has a 3-pillar strategy on carbon dioxide and cars. Included in the EU strategy is a voluntary commitment from the car industry to reduce carbon dioxide emissions from new cars. The easiest way of lowering the emissions is by using alternative fuels and engines.

Den tunna röda linjen : identitet inom arkeologisk teori och metod

THE THIN RED LINE ? Identity in theory and method With this essay I want to explore some possibilities with the term identity within archaeology. Identity is a term best understood in the light of different scientific approaches. For instance the anthropological and historical angel combined with the quality of archaeology, as is the case in this essay. By combining these approaches, I create a (clarification) method of exploring traces of identity.By analysing two different graves from Scania, having a negligible number of artefacts from the Viking Age, and three graves from Bornholm, known for its large number of finds from this period, I test the ability of my method.

Elförbrukningen i svenska hushåll : En analys inom projektet ?Förbättrad energistatistik i bebyggelsen? för Energimyndigheten

Energimyndigheten har drivit ett projekt kallat ?Förbättrad energistatistik i bebyggelsen? för att få mer kunskap om energianvändningen i byggnader.  Denna rapport fokuserar på ?Mätning av hushållsel på apparatnivå? som var ett delprojekt.Diverse regressionsmodeller används i denna rapport för att undersöka sambandet mellan elanvändningen och de olika förklarande variablerna, som exempelvis hushållens bakgrundsvariabler, hushållstyp och geografiska läge, elförbrukningen av olika elapparater samt antalet elapparater.Datamaterialet innefattar 389 hushåll där de flesta är spridda runt om i Mälardalen. Ett fåtal mätningar gjordes på hushåll i Kiruna och Malmö.Slutsatsen vi kan dra från denna uppsats är att hushållens bakgrund, hustyp, geografiska läge och antal elapparater samt dessa apparaters typ har relevans för elförbrukningen i ett hushåll..

Portfolio som arbetsverktyg i förskola och skola - barns beskrivningar av sin portfolio

The study sheds light on pupils individual plans of development and portfolios from the perspective of children. It has an ethnographic standpoint. It was carried out on children and pupils in pre-school, pre-school class and third grade. By further investigating how children and pupils use their individual development plans and portfolios, in which settings and to whom they communicate them, this study is able to grasp the discourse that is created around the instrument itself. This study is also interested in and aims to find the theoretical frame, in essence, which envelops both the construction of childhood and children?s own activities within the limitations and opportunities that this structure offers.

Kvinnofridskränkning - ett stort samhällsproblem : En fallstudie av hur ett par kommuner i Kronobergs län hanterar kvinnovåldsproblematiken

Equal opportunity issues are considered to have a clear position in Swedish policy and the making of Swedish gender policy is considered a precursor. Though many experts and scientists have shed light on the fact that the issue of women assault has had a less stable development than other gender issues such as child care, the labour market etc. within the Swedish society, and that it does not attract the wide political support it needs. The purpose of this study is to demonstrate the Municipalities', in the county of Kronoberg, policy on the issue of women assault within their local policies of equality. In my thesis I have chosen a theoretical framework that is built on a dilemma of justice based on three different dimensions; the extent, content and influence of the local policies.

Kingdon´s Theory of the Agenda Setting Process, Discourse Theory and Institutional Theory the thesis seek to visualize the implications of structures, central actors and discourses on the reform processes.

Skeva begär : En queerstudie av Karin Boyes lyrik

This essay examines the way the recurring motifs in Karin Boye's poetry might be read as expressions of queer or subversive desire. The fact that the lyrical I is not gendered in the poems opens up for a queer reading. In adherence to Sara Ahmed's notion of desire lines and sexual orientation I discuss the spatial aspects of desire, and explore the positions and movements of the lyrical I in Boye's poetic landscape as deviations from the concept of the straight and marked path, into the queer and unknown.I trace desire in Boye's poetry mainly through the themes of nature and night, and the ways in which these phenomena deviate from the normative structures laid out by the poems. Usually the motifs of night (such as fog, shadows and darkness) are associated with the fading of the senses. The night obscures the vision of the lyrical I and wraps them in heavy silence, making them experience and desire in new ways. Through motifs related to nature Boye formulates a feminine, matriarchal myth.
