This master thesis investigates the possibilities of using GPS-information from trains to create a model of a railway system, register the routes of the the trains and predict how the trains will travel in the railway system.The thesis work was done at Icomera AB which is a company that specializes in internet connected vehicle solutions.We describe how the GPS-information is sent from the trains in the form of samples and investigate limitations and possibilities with the available information. About three million samples from 83 SJ-trains were analysed and the samples were filtered with the intent of removing erroneous information. We here found that about 30 % of the samples from the trains were unreliable.A solution for how the samples from the trains can be used to create a model of the railway system traveled by the trains is presented. We use a large set of historical samples and use cluster nodes and Hermite curves to generate a graph that represent the railway system with stations, nodes and the railway itself. A fully automatic solution is not presented since it did not fit into the time frame of the thesis; instead we created a simple tool which can be used to manually finish the model of the railway system.Furthermore, we describe how the railway system and the samples from the train can be used to register the routes the trains travel.

In the autumn of 2012 a debate started in Swedish media about racial stereotypes and content in children's literature. Some voices wanted to weed out titles such as Tintin i Kongo (Tintin in the Congo) and the character Lilla hjärtat from Liten Skär och alla Brokiga (Little Pink & Brokiga), while others claimed that it was against our freedom of speech. In this essay I intend to interview librarians to find out if and how the debate has affected their work with purchase and weeding. I will also analyze their purchase policy to find out if it mentions racism and how the policies are applied in practice. As theory I'm using Strömbergs theory regarding three aspects of racism and Klassons theory about three different kinds of librarian roles.

Scania is among the leading companies in the heavy vehicle industry. Scania also assemble engines for their trucks and buses, as well as to external marine and industrial applications. Wrongly assembled parts leads to quality problems, which makes it important to secure that the assembly is correct. To do this Design For Assembly (DFA) is used to describe how parts should become easier to assemble. Scania?s production unit for engine assembly has had a working method for DFA in the shape of a checklist, which is not used.

AbstractThe ability to read and write is a very important skill in today?s information based society. Most of us learn how to read and write, but not everyone is blessed to do this without struggle. Dyslexia is a very common learning disability and therefore I found it interesting to study how teachers teach students with dyslexia.By studying the literature and by interviewing teachers, I found that dyslexia is a very complex disability. The teachers have to adapt their way of teaching in a way that a student with dyslexia can participate.

The purpose of this study is to understand school counselors knowledge and work with cyber bullying among students. Our study is based on the result from eight qualitative semi-structured interviews. These interviews were conducted with school counselors working at elementary and high school in the state of Kronoberg, Sweden. Our theoretical base is human services organizations, street level bureaucrats and acting space. Our study shows that school counselors have adopted cyber bullying in various ways which has an impact on their knowledge and systematical work regarding this question.

The purpose of this master thesis has been to find different solutions to the design of a headlamp with a cluster of three or possibly four high power LEDs (Light Emitting Diodes). During the work, two different problems have been considered; how to design a lens in order to shape the light beam in a desirable way, and how to design a cooling system which will lower the temperature of the LEDs as efficiently as possible, still taking into account the geometry set by the optical solution as well as other given geometries. The results presented in this thesis are partly the outcome of a literature study, but derive mainly from a number of tests and measurements made on two test rigs and one concept prototype..

The first browser war took place during the second half the 1990s, and Internet Explorer cameout as the winner over Netscape Navigator. Today a new browser war is being fought withmany competitors and the future is uncertain. The purpose of the thesis is to find out how theweb browser market has developed since the start of the previous conflict, and we ask ourselveshow it will continue to develop in the future. This is accomplished with, among otherthings, interviews, tests and already existing statistics. The thesis' conclusions shows that theweb browser market has developed in a positive way from several perspectives, both for theusers as well as for the web developers.

Denna litteraturstudie gjordes i syfte att belysa vad som har betydelse för att ett lärande ska främjas i skolan med diskussioner och samtal i fokus. Genom att studera tidigare forskning angående dialog i klassrummet syftade denna studie till att besvara konversationens betydelse för elevers lärande. I denna systematiska litteraturstudie kopplades ett sociokulturellt perspektiv in för att undersöka vad som har betydelse för att samtal ska vara till hjälp för elevers lärande. I resultatet kom flera olika faktorer fram som var främjande för elevers lärande i samtal och diskussioner. Betydelsen av deliberativa samtal visades vara olika efter de studier som undersöktes, där betydelsen visades vara antingen positiv eller resultatlös.

Shock absorber units play a key role in establishing the driving dynamics and performance of automobiles. Öhlins Racing has manufactured high-tech automotive shock absorbers for over 30 years. Öhlins Racing?s advanced technology has contributed to over 200 world championships in automobile racing. Öhlin?s manufacturing process has long utilized automated fluid filling equipment during the final shock absorber unit assembly stage. The filling process consists of vacuum pumping the shock absorber unit and subsequent transfer of fluid. Vacuum pumping is necessary to remove residual air from the shock absorber unit prior to initiating the liquid filling stage. The presence of undesirable gases drastically compromises the performance of a shock absorber. The filling degree, defined as the final ratio of air to oil, is determined by the specific filling protocol as well as the specific equipment utilized.The current investigation aims to develop a viable technique to accurately determine residual air content in shock absorber units. If the filling degree can be appropriately quantified for a specific manufacturing process, then the air/oil ratio may be quantitatively related to shock absorber performance. The utilized measurement method must be completely integrated into the manufacturing process to guarantee shock absorber performance specifications according to the manufacturer?s standards. By utilizing the measurement method developed in this work, the manufacturing process, manufacturing equipment and product specifications can all be tailored to provide improved filling conditions.The developed measurement method provides accurate quantification of the filling degree under a wide range of processing conditions. The method establishes the relative quantity of air in the shock absorber unit by performing in-situ compressibility tests. The fill ratio can be controlled and varied by manipulating the vacuum pressure exerted during the filling process. Performance tests, however, indicate no correlation between filling degree and unit performance..

The essay is about how teenagers around 18 years of age in a small town in Sweden talk about gender, body and sexuality. The study is based on two focus group interviews with five boys and four girls. We have then thematized and analyzed the material with queer theory.The results show how young people see heterosexuality as something 'natural' and gender as biologically determined. The teenagers are critical towards anything that deviates from the traditional nuclear family consisting of mother, father and children. Norms are created in their speech as some of them acts as so called "border guards" for these norms.

The essay is about the Nobel Library's investments in fiction, the change of certain linguisticareas since 1904 and the purchase policy of the Library. The paper contains an introductoryhistorical chapter, where I describe the history of the Swedish Academy, the life and willof Alfred Nobel and in conclusion a description of the Nobel library of the Swedish Academy.When writing this essay I have used a combined qualitative and quantitative method, meaningthat I have interviewed the librarians of the Nobel Library, studied the purchase catalogues,and kept statistics over the books.in different linguistic areas purchased since 1904 onwardwith an emphasize on years ending with "4". The outcome of this survey is that the purchaseof books within the different speech areas doesn't vary as much as first expected, and thatthere rises and falls within all the linguistic areas which could be further explored..

There are different ways of developing a second language. The purpose of this qualitative study is to investigate whether and possibly how music, focused on singing, can improve the development of Swedish as a second language. Through interviews with three vocal teachers, from three different schools in Sweden, and observations of one of the vocal teachers, information about how they work and think about the subject has been collected. The vocal teachers teach groups of second language learners by singing songs made especially for second language learning. The vocal teachers consider singing beneficial in the development of the pronunciation and improvement of the prosody, which affects the students? capacity to sound like a native Swedish speaker.

Den här uppsatsen är ett försök till att analysera ny digital och digitaliserad litteratur med hjälp utav medieteorier och intervjuer med lokala aktörer i det litterära produktionsfältet, först och främst förläggare. Jag har två mål med min avhandling: att ge en överblick över hur dagens digitala landskap ser ut och hur vi, både som kulturkonsumenter och -producenter kan förhålla oss till dessa nya medier när de är så pass abstrakta som de är idag..

The aim of the following paper has been to test the democratic peace theory through applying it on the conflict between Russia and Georgia in 2008.  This to either falsify the theory or come to the conclusion that the states? democracy was not satisfactory in regards to the definition of liberal democracy. The questions asked are: Was Russia and Georgia democratic states? Is democracy a protection from war? And which aspects of the liberal democratic theory, if any, were not satisfactory in either of the countries? The results show that the democratic peace theory is valid in this case and that neither one of the states were democratic.

Företag har idag ett allt större behov av att utmärka sig på marknaden, nödvändigt för att göra detta måste företagen bygga upp en identitet. Vi kommer att fokusera på de visuella aspekterna av identiteten och därmed rikta in oss på företagens ?ansikte?, logotypen. En logotyp kan bland annat bestå av ett namn, en symbol eller en bild. Den här uppsatsen handlar om logotyper med abstrakta symboler.
