I detta projekt har vi fördjupat oss i en glidlagerkonstruktion som befinner sig i en skruvpress. Skruvpressen kompakterar en okänd massa som är sekretessbelagd. Robustus har ett förslag på överdimensionering av det nuvarande glidlagret. Målet med projektet var att analysera och optimera några glidlager i förhållande till det befintliga glidlagret samt att ta hänsyn till materialval och den miljö som lagret kommer att befinner sig i. Det som analyserna och optimeringen visade var att det befintliga glidlagret hade den bästa geometrin bland alla lösningar men inte det optimala materialet.

Stress is something that has increased in recent decades among adolescents. Several reports indicate that young people today are more stressed because of the many demands they wear. They should be good in school, achievement expectations, get an education or job, make choices and think about their future. The purpose of our essay is that we want to explore and gain an understanding of how young people in the third grade in high school looks to stress. To conduct this study, we used a qualitative approach, by doing interviews with 10 high school students attending third grade at Västerviks gymnasium. The result we got out of the interviews was that young people experience stress differently, depending on their different as individuals. We found that there are different causes of stress, such as school, media, friends, demands from various quarters and choosing education.The interviews showed that some kind of stress was possible to handle for the adolescents, for instance by making schedule. Some stress from society was, on the other hand, more difficult to avoid..

Det blir allt vanligare idag att de stora modehusen skapar barnkollektioner. Internationellt sätt har nästan varje stor designer redan gett sig in på barnklädesmarknaden. Jag valde dock att inte fokusera på den internationella marknaden utan undersöka hur den såg ut i Sverige med svenska modeföretag som hade olika positioner. Jag plockade ut ett antal märken som skiljde sig markant i målgrupp. Företagen jag har valt att ha med till studien är Acne, KappAhl och Polarn O.

This thesis work has been performed at the Division of Assembly Technology at Linköping University for a period of ten weeks. The work is part of the project ProFlexA, which is a research project in collaboration between Linköping University, Lund University, and industrial partners such as Combi Wear Parts and Smålands Stålgjuteri AB.The casting process creates random incurred burrs and defects, which must be removed during a cleaning process to make sure that the cast can be sold. Automation has long been sought for the cleaning of castings due to, among other things, poor working conditions for staff, but this has proved difficult to implement with today's technology. Automation has for some time been available for more capital strong companies with large annual volumes, but for smaller companies with small-and medium-sized volumes, automation has not been an option.The goal of ProFlexA is to develop an automated cleaning cell aimed at small-and medium-sized volumes.The goal of the thesis is to do a pre study at ProFlexA?s partners on cleaning of castings, and develop concepts for automated cleaning of castings.By recording the process and cycle times, the cleaning of castings has been documented as it works today, and on this basis, information and statistics has been compiled.

Every year more than 6000 thefts, to a value of 1.5 billion SEK, are reportedwithin the Swedish building trade. Plus all the indirect costs of having theconstruction site standing still.SafeTool is a newly started company that will try to prevent this problem witha modern technology solution.The key to SafeTool?s solution is RFID ? Radio Frequency Identification ? andthe solution looks like this;All tools are stored in a container on the construction site. Every tool isequipped with a RFID-tag that uniquely identifies the tool. With antennas in thecontainer it is possible to detect when a tool is leaving the container and whenit comes back.

The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.

We live in a society where we are not bound to one place. We are encouraged to be mobile and constantly moving between different locations. The life in a convent is a contrast to this; nuns live at a specific place they are bounded to by vows and can not leave. The sisters in the convent of St. Birgitta, Pax Mariae have promised to stay at the same place and live by the rules of the convent.

The purpose of this thesis is to outline an appropriate model in order for companies to successfully act and compete physically as wholesalers at the same time as acting on the virtual market by selling directly to the end consumer. The approach of this thesis is hermeneutical and abductive with elements of hypothetically deductive approach. Our research has a qualitative research strategy based on case studies and interviews as well as on secondary data. Interviews were conducted with the case company JaymJay Wear AB as well as with other companies, so called mini cases. The secondary data consists mainly of textbooks, web sites and journals.

The aim of this thesis is to explore the job satisfaction of librarians and try to nuance stereotypes, which the public has and which still exist in massmedia concerning librarians and their work. The study is qualitative and based mainly on semistructured interviews with ten libraries born between 1937s and 1973s of which eight are women and two men. Furthermore, I have divided them into two groups according to age in order to see if there are differencies between the older and the younger concerning job satisfaction. In addition, I have used participant observation to some extent. My assumption is that job satisfaction is effected both by individual factors and environmental factors at work.

The purpose of this study is to find out how Swedish Muslim girls use Facebook and its functions in constructing their Muslim identity on the platform. The study is based on a qualitative method which consists of nine interviews with Swedish Muslim girls between the ages 17-23 and who use Facebook daily.The study is based on the view of Facebook as a scene where individuals can perform for an audience. I have used Erving Coffman?s dramaturgical perspective that explains why individuals appear in an appropriate manner to achieve confirmation from their audience. I also used theories about identity construction, community and the theory about how individuals create a social presence online.

The aim with this study was to investigate the effects a change of manufacturing process would have on the mechanical properties of drill bits made of a WC/Co composite used for stone cutting. The method used today is sintering, where the material is heated in a conventional sintering oven. The other method was microwave sintering, where the material is heated by radiation in the microwave region. Also an investigation of the manufacturing cost were made.The main difference between the two heating methods is that the conventional way is a rather slow process and the microwave method is very fast. The material is also heated homogeniously in the method with mirowaves, aposed to the case with the conventional sintering where the material is heated from the outside in.This makes the material harder and more wear resistent.

Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.

Fashion creates reactions. It is a type of art form that constantly needs to be updated. This is the thrilling part about fashion, but it is also the part that can create unintentional reactions.In this essay I will examine two garments that have achieved a great amount of media coverage, both in Sweden and abroad. One of them is a jumpsuit from H&M that was criticized because of the resemblance to the uniform worn by the Peshmerga-soldiers in Kurdistan. The other garment is a children?s sweater launched by Zara.

The purpose of this study was to describe patients? experiences when living with a venous leg ulcer in physical, psychological and social perspectives. The articles used to describe this condition were found in the databases: PubMed and Cinahl. Ten articles were included in the result: five with a qualitative approach, two with a quantitative approach and three with both qualitative and quantitative approaches. The results were presented through three headings: physical, psychological and social.

Denna uppsats syftar till att kvalitativt undersöka hur kvinnor porträtteras i femutvalda avsnitt av The Hills (MTV), med fokus på deras beteende och uppträdande ifrågor som karriär, utseende och relationer till män. Detta undersöks med hjälp av ettanalysschema som har utformats utifrån Keith Selbys och Ron Cowderysanalysmodell för att studera television. Undersökningen vilar på en genusteoretisk grund och teorier som används är blandannat R.W. Connells hegemoniska maskulinitet, Yvonne Hirdmans genuskontrakt,Laura Mulveys ?the male gaze? och en vidare utveckling av Foucaults teori om ?thepanopticon?. Detta kompletteras med forskning av bland annat Rosalind Gill, AngelaMcRobbie och Hillevi Ganetz. I min analys framkommer att det förekommer väldigt få skildringar av kvinnor varsbeteende utmanar en traditionell syn på kvinnligt uppförande.
