Utvärdering av en ny typ av lagerinbyggnad för traktionsmotorer
The thesis evaluates a new kind of bearing arrangement in a traction motor that ABB hasdeveloped. Since the arrangement is designed in a new and innovative way it needs to beevaluated to see if it is safe to use. In today?s traction motors, bearings with a big internalclearance (C4-clearance) are used. The basic idea of the new arrangement is to reduce the fitsbetween the bearing and shaft/house.
Minimalytor och Björlings problem
This paper gives an introduction to the theory of minimal surfaces. It is in- tended for undergraduate students with some basic knowledge of differential geometry and complex analysis.After defining the concept of minimal surface and giving a brief histo- rical survey, we look at some well-known minimal surfaces and a few of their characteristic properties. The connection between minimal surfaces and harmonic functions is discussed and the Weierstrass-Enneper represen- tation formulas are introduced. We also present Bjo?rling?s problem and give some examples. .
Idéer om samhälle och individ : Abortdebatten under 1960- och 1970-tal med inriktning på realpolitik och ideologi
Julia Rolandsdotter, Idéer om samhälle och individ: Abortdebatten under 1960- och 1970-tal med inriktning på realpolitik och ideologi, Uppsala Universitet: Institutionen för idé- och lärdomshistoria, C-uppsats, HT 2013.This essay aims to investigate and scrutinize the debate surrounding abortion during the years of 1964 and 1974 respectively. By analyzing elements of different opinions in the debate from daily press, a wide range of aspects concerning the issues of free abortion have been distinguishable. This analysis shows that the abortion debate was, to a high degree, a question of Realpolitik and ideology whereas the differences over time have been visible rather than the differences between parties of varying opinion. By applying the theories of Ian Hacking concerning the effects of categorization, ideas surrounding people and society among others, have been highlighted in the debate. In 1964 we see ideas about the woman as motherly or a victim and the society as defective or exposed among other factors.
Godshantering av flygunderhållsartiklar - En värdeflödesanalys ur ett förbättringsperspektiv
Saab Component Maintenance in Linköping, Sweden, offers maintenance, repair andoverhaul (MRO) services for civilian and military aircraft components. Lately, thedepartment has struggled with slow throughput rates, despite various counteractingattempts. Studies show, that large parts of the delays derive from the logisticsdepartment where goods arrive and dispatch. Therefore, Saab wants to carry out anextensive analysis of the department in order to further investigate what is causing itsslow throughput rates.The thesis begins with extensive mapping over Component Maintenances whole valuestream to find out how departments interact with each other and which roleindividual departments have in the total supply chain. Out of 13 000 different partnumbers, components were divided into five product families.
Fri rörlighet för varor på den inre marknaden och principen om ömsesidigt erkännande
The aim of this thesis is to identify some of the obstacles to trade, that occurs on the common market, and to analyse the errors that still occurs in the national authorities application of the principle of mutual recognition. Is the principle of mutual recognition sufficient for the creation of a common market, or is there a need for additional measures to cope with the obstacles to trade that still exists on the common market? The problems related to the incorrect procedures of the national authorities and the fact that undertakings prefer to bring their products in to line with the rules of every single member state must be solved, if the principle of mutual recognition is to become trustworthy. On some areas, harmonisation ought to be chosen above the principle of mutual recognition, but in other cases an increased administrative collaboration, mandatory training for the national authorities or information campaigns intended mainly for undertakings could be the answer. The possibility to help undertakings to sue member states for damages should also be investigated.
Att existera i ögonblicket -Töj, en textil sittmöbel
This project started with an exploration of geometric shapes and textile materials. It resulted in a chair made out of textile bands with different elasticity. The surface for sitting is flat when the chair is not used, and changes in the moment you sit down and gets a new shape. A piece of furniture that adapts to each individual. The chair emphasizes the important relationship between human and product as the person using it becomes a part of the chair for a moment..
Den bäcknära zonen vid små skogliga vattendrag i Värmland : generell beskrivning, förekomst av traktorspår samt kvicksilverhalter i körpåverkat ytvatten
Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

Gamification ? Spelelement och speldesign i arbetslivet
Syftet med studien är att bidra till kunskap och förståelse kring fenomenet gamification. Denna kartläggning bidrar till att klargöra för- och nackdelar, möjligheter och risker samt eventuella fallgropar med gamification. Om en organisation är medveten om dessa aspekter kring fenomenet minskar riskerna för att någonting ska gå fel, vilket potentiellt skulle kunna bli kostsamt.Studien vilar på en teoretisk referensram hämtad från såväl managmenent- som psykologiforskningen. Förväntansteorin, self determination theory, flow, McGregors Teori X och Y, principal-agentteorin är några av de teorier som används för analysen av gamification.Då det handlar om en kartläggning kring ett relativt nytt fenomen behandlas flera exempel på gamification hämtade från företag som verkar inom branschen. En intervju med speldesignern Henrik Englund finns också med, samt en fallstudie kring polismyndighetens omskrivna användning av spelelement.
Gamification: mot en definition : En kvalitativ studie och kartläggning av begreppet gamification och dess framtida implementering
Uppsatsens huvudsakliga syfte är att utforska och kartlägga begreppet gamification. Syftet operationaliseras i tre frågeställningar. Vad finns det för likheter respektive skillnader i synen på Gamification mellan ett antal yrkesverksamma inom Gamification? Hur ser yrkesverksamma med olika bakgrunder inom psykologi, pedagogik och marknadsföring på framtiden för Gamification och dess användningsområde? Vilka för- och nackdelar kan finnas med Gamification? Uppsatsen teoretiska utgångspunkter omfattar de psykologiska krafterna bakom spel som flow och motivation, teorier om det praktiska användandet av gamification och teorier om Generation Y. För att samla empiri har kvalitativ metod använts i form av semistrukturerade explorativa intervjuer där yrkesverksamma inom gamification har intervjuats.
Du sköna fria värld : En analys av globaliseringsdebatten utifrån ett makt- och hegemoniperspektiv
This essay aims to emphasize and clarify the positions that exist within the current globalization debate. The positions are the neo-liberal, the opponents, the pragmatists and the skeptics. The text presents and explains their ideological, moral and political positions and beliefs about the world, the nation state, the society and the individual; in light of Steven Lukes? and Antonio Gramsci's theories regarding the interaction and the relationship between power and hegemony. The methodological starting point is the ideology-critical analysis; in which their arguments in the current globalization debate is highlighted and categorized.
Melodibasens etablering och utveckling - reflektioner kring accordeon i undervisning
Title: The development of Free BassIn this work I will explain how the accordion with free bass was developed in Sweden. I will also describe how the people, teachers and musicians, did respond when it was introduced. In this study I investigate Swedish freebass teachers' reflections upon their educational issues. I want to look deeper at how they are reflecting over these two systems, and how they are using them in their daily work. By reading some accordion magazines from the era as a method, I did researching and then I analyzed the articles written about the subject.
Viljebegreppet och psykologin : En studie av psykologins framväxt som vetenskap i Sverige genom en analys av viljebegreppets betydelseförändring
The aim of this study is to elucidate the process in which psychology was separated from philosophy and established itself as a distinct academic discipline in Sweden. I argue that the concept of will, as well as the concepts of thinking and emotion, have a lot to tell us about the rise of academic psychology in Sweden. This is done through an analysis of psychology textbooks, encyclopaedia-articles and academic texts on the themes will and psychology, from around 1800 till 1950.Prior to the establishment of the first chair of psychology in Uppsala 1948, the discipline was above all a part of the philosophical discipline. For psychology to become a science of its own, it was crucial to obtain a position among the empirical sciences. It thus had to distance itself from philosophy, and in particular from metaphysics.

Urinsorterande toaletter : rensning av stopp samt uppsamling och attityder
It is important that the current urine separating systems are evaluated to allow improvements to be made and consequently increase their future propagation. In order to increase the knowledge about urine separating systems this study was made. It included, among other things, measurements of amounts of urine as well as of the composition of urine collected at Nytorgsgatan 4 in the city of Hallsberg. The study was increased after an inquiry that also included the district of Understenshöjden in the city of Stockholm. In the inquiry, the users were asked questions about odour, cleaning of toilets and occurrence of blockages in the urine water locks etc.
