Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

This essay is reading the Swedish author Stig Larssons debut Autisterna [The Autists] (1979) in the light of Gérard Genettes narratology and the time philosophy of Gilles Deleuze. The focus of the essay is time and how it is seemingly dissolved. The essay maps out a chronology of the non-chronological novel and from there discusses the breaking up of the empirical time. The essay uses Deleuze to explore the time-image of the novel to see how it is built up in the text for example by literary anyspace-whatevers. Hence the title, Anytime-whatever.

Idrottsanläggningen Enavallen i centrala Enköping ska flyttas och ytan ska bebyggas med bostäder. Det geografiska läget och det faktum att området delvis gränsar till Enköpingsån, vars roll i staden Enköpings kommun har som ambition att utveckla, gör Enavallen till ett intressant område att studera. Området ligger dessutom nära befintliga villaområden, en prisbelönt park samt strax intill den centrala rutnätsstad som centrum utgör. Området studerades med analysverktyget Space Syntax för att ge en tydligare bild över de befintliga gångstråk som finns i staden. Analyserna visade att Enavallens potential begränsades av det faktum att ån spärrar av hela norra delen av området. Dessutom är idrottsplatsen, som upptar den största delen av ytan på Enavallen, till stora delar inte utformad för genomströmmande gångtrafik. En förutsättning för exploateringen av Enavallen är att antalet bostäder i området styrs av att försäljningen av bostäderna ska finansiera den nya idrottsplatsen som ska byggas på en närliggande plats.

Sweden has a long tradition of collecting documents by way of a process of legal deposit of copies. Its aim is to ensure the availability of material for research, cultural preservation and citizens? right to free information. New forms of publications, made possible by technical advances, are not accommodated in the traditional deposit submission criteria. Certain information accordingly risks being lost.

Uppsatsens syfte är att, med hjälp av postkolonial teori belysa matens roll i några personers migration till Sverige. Nio stycken informanter har berättat om sina erfarenheter och minnen av hemlandets mat och maten i Sverige och på olika sätt diskuterat sin personliga och kollektiva utveckling ur ett matperspektiv. Resultatet visar att mat spelar en viktig roll för gemenskaps- och tillhörighetskänslan i sociala situationer samt att informanterna ibland upplever att de hamnar mellan två kulturella gemenskaper, ett slags ?third space? med möjlighet att föra dessa närmare varandra med hjälp av hybridisering. Mat blir då ett konkret sätt att både se och upptäcka den utvecklingen men också någonting att bygga nya gemenskaper runt..

Täby galoppfällt kommer att genomgå en förvandling som innebär att ca 4000 nya bostäder kommer att tillföras under en 15 års period. Täby kom-mun tillsammans med byggherrarna JM/Skanska och Viggbyholms fastig-hets AB driver projektet med målet om en sammanhållen, hållbar park i stad. I snitt flyttar svensken 11 gånger under sin livstid. Detta innebär att de som flyttar in i startskedet av utbyggnaden med stor sannolikhet kommer att hinna flytta ut innan hela stadsdelen är färdigt utbyggd. Att stadsdelens ut-byggnad sker på ett sådant sätt att målen om en hållbar och sammanhållen stad inte bara uppfylls i och med projektets färdigställande ut även bäddas in som en röd tråd under hela byggtiden är alltså mycket viktig.

Tyr ? A historical and comparative study of configurations and formations connected to the Old Norse god Tyr. Klas af Edholm This thesis has two aims. One is a discussion of the history of the study of Old Norse religion and related aspects, centered on how general tendencies within the area of research have affected the interpretations of the god *T?waz/Tyr.

The topic of interest is why Swedish unemployment after OPEC - 1 remained exceptionally low, compared to the OECD average. The object of study is the evolution of welfare institutions, like the Rehn ? Meidner model, after WWII, and the aim is to explore why the institution of solidaristic wage bargaining collapsed coming the nineties. Deployed theoretical perspectives are how domestic institutions determine a country's adaptation to alterations of the international economic system. However, equally important are how policy objectives, like full employment, becomes institutionalized and therefore guides the actions undertaken.

En effektiv och populär grafisk effekt för realtidsgrafik är Screen-Space Ambient Occlusion(SSAO). Teknikens nackdel är brusiga artefakter som kan dämpas med blur filtrering. Detta arbete studerar upplevelsen av defekterna i SSAO med en användarstudie. Arbetet implementerar en renderare som renderar bildrutor från kameraåkningar och ett visningsprogram som används i experimentgenomförandet. Renderade bilder utan och med aktiv blur-filtrering visas för försökspersoner som får beskriva om de ser skillnader mellan bilderna och välja vilken bild de föredrar.

The purpose of warning labels used by governments is to decrease consumption. In Sweden, the mandatory warning labels are designed according to statutory guidelines, and not according to research on attention-grabbing graphic elements. This results in a belief that the attention toward the warning labels is poor. An extensive experiment underlies this study, which has the purpose of providing insights to the effects that warnings, warning design, and warning content has on attention, attitudes and behavior in print ads. The study shows that, even though the standard design and content has lost much of its potential to communicate the warning, it gains more attention compared to a warning label with new design and content.

This master thesis was conducted at Motala Wire Works Ltd (MWW) in Motala during the autumn and winter of 2007-2008. The thesis named ?Future layout of Motala Wire Works? focuses on making a better planed layout for the factory, which also take in to consideration future changes.Motala Wire Work produces wire mesh products of varying sorts for the white goods industry. The factory was started by Electrolux during the 1950?s.

The subject for our bachelor thesis is how sugar is portrayed in Aftonbladet. By analyzing newspapers from 1995 and 2013 we wanted to research if the portrayal of sugar has changed during the years. We have noticed that there is a trend of being healthy and fit today. ?Strong is the new skinny? is a quote we can see in social media and on blogs today.

Many enterprises have shortcomings in the transfer of information between different departments. Furthermore, routines for maintaining knowledge in order to be able to use this experience in the future are often lacking. Time and resources spent on improving these systems and procedures can provide significant benefits in terms of saved time and reduced costs in the later stages of a project. The benefit of this is not only a greater clarity and a reduced risk of misunderstandings, but also the preservation of knowledge that would otherwise be lost.The aim of this study has been to examine the process of information transfer and the transfer of knowledge between the calculus department and production manager in projects at Erlandsson Bygg i Öst AB. An additional aim was suggestions for improvements in the calculation handover and at the end of a project, where it was possible.The study was primarily conducted through literature studies and interviews.

Boulognerskogen is a park in the central of Skövde that have had a health resort, paths for strolling, outdoor-bath, outdoor-sport areas and events. During the 1970:th there was a lack of interest for the park and very few visited it. By a motion from a resident in Skövde wich proposes that a city playground will be build in Boulognerskogen gave me an opportunity to investigate how the potential of the park can be used to create a funny and nice place to visit for children in company with adults. By a program that contains the main goals and design program for a city playground in Boulognerskogen, I wanted to present a proposal that could meet childrens needs to play and to use the conditions of the place to create places to play in, and where children in company with adults could be together. To reach this, I wanted to try different methods that could lead to a proposal that was well supported by children and adults, and wich was possible to use by the local authority in their further actions. The methods that I used was therefor an important part of the work. I have choosen to define the concept "city playground" as a greater playground situated in the center of the town that are suitable for outings and as a meetingplace, with a varation in playground attractions and promote children and adults to be together, aiming at younger children in the ages of 1-10 years in company with adults, but should also give space to activities of other groups.

During an investigation of animal welfare in animal production, the focus has for a long time been focused on the absence of stress, suffering and injuries, and positive emotions have not been prioritized. However, in recent years that has been drastically changed. The public interest have increased for buying animal products from animals that have had a decent life, which have led to that play, exploratory behavior and other positive behaviours has come to play a significant role in welfare assessment. The welfare of cattle is difficult to assess since there is currently no ancestors to study, it is thus difficult to determine which behaviors can be regarded as natural and thus positively related, acordingly the welfare of cattle have been forgotten and research on positive emotions of cattle have not been prioritized. The aim of this study was to observe which behavior growing cattle performe, and if there was any differences of which kind of behavior that was observed, if the cattle is keept on slatted floor or on a deep straw bedding. Furthermore, antoher purpose was to investigate if the observed behaviours indicate a positive, negative or natural welfare, and if it is possible to use the observed behaviours in a welfare assessment.
