This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

A carnival can not be stopped! A design pedagogical study of children and norms In Basel, the only Protestant carnival in Europe takes place. The carnival is called Fasnacht. For three days, there is a wild and uninhibited play with tradition, crossing borders and social criticism.The aim of this thesis is to expand the understanding of the concept of the carnival, and how to use it for an educational purpose. Three children from Basel have been involved in an workshop where they designed and talked about norms and power structures through the carnivalesque principle. The study is based on the questions: How can you use the carnival as a starting point for designing and talking about norms and power structures together with children? And; How can the design process support such a project? To spot this, I made arrangements for a design educational project.

In recent years, global organizations safeguarding financial stability has started to track commercial property markets. One of the reasons for this refers to the fact that commercial property constitutes a large share of bank lending. Simultaneously, bank exposures to commercial property are extensive and risky since collateral values are strongly correlated to borrowers cash flows. Since banks are viewed to play a key role for financial stability, studying the relationship is well motivated. To better understand how commercial property markets interact with financial stability, this paper develops an econometric model for studying the commercial rental market.

The deregulation during the last decade within the airline businesses have called upon a more fierce competition among airlines. This fact forces airlines to continuously focus on service development in order to offer attractive solutions to satisfy customers changing needs and stay competitive. This paper focuses on service development at Scandinavian Airlines. The aim of this case study is to examine the sources of information used in service development and new service development at Scandinavian Airlines. Further the aim is to examine whether information derived from customers can be shown to play a more important role in either service development or new service development.

Safety in the construction industry has become a question of top priority in recent years. Despite a massive investment of time, money and knowledge, the occur-rence of fatal accidents in Sweden alone is around one a month.The purpose of this study is therefore to improve the safety on the construction site. By an examination of the role of the safety agents and their cooperation with the construction workers and supervisors as well as examine how safety agents can improve safety on the construction site, which is the goal of the study.Four questions were formulated based on the purpose and the goal of the study.The methods used to answer the questions were a questionnaire survey, multiple interviews, a literature review and a document analysis.The report describes the safety agent?s role as a complex one with many different tasks. The role of the safety agents is regulated in the health and safety law, but it can sometimes be difficult to interpret and the agents can therefore interpret their role differently.

The purpose of this essay has been to describe and compare the personal qualities that the Swedish newspaper Dagens Nyheter (DN) tried to associate Barack Obama and John McCain with during the American presidential election campaign 2008. The main question to be answered is: What social and physical characters as well as what personal experiences, interest and resources did DN tried to emphasize regarding John McCain and Barack Obama during the American presidential election campaign 2008. The theoretical starting-point has been John B Thompson?s theory of the mediated publicity and John Corner´s theory of political persona and spheres of action. Various DN news texts, in all 38 articles, have been examined by content analysis from 25th of august to the 4th of November.

AbstractPolitical Science, level III thesisSpring semester 2010Author: Emelie AlfredssonSupervisor: Tomas Mitander"A Changed Leadership? - A study of the EU leadership from a institutional standpoint, related to multilateral environmental negotiations"The EU has for a relatively long time considered itself a leader in the environmental policy area as a whole as well as in multilateral environmental negotiations. This study attempts to classify and identify the European leadership with the purpose of relating it to the institutional framework of the Union.

Abstract Back ground: Home based care is a meaningful activity giving patients and their families a chance to live their lives as close to normal as possible. Advanced palliative care is today provided at home, although geography does play a role in shaping that care. A rural setting can mean that conditions for such care differ from those in urban areas.Purpose: To describe the experiences of district nurses in palliative home care settings in a rural community.Method: Semi structured interviews with seven district nurses. The interviews were recorded digitally and transcribed in a precise fashion. A method of qualitative analysis of the contents, inspired by Burnard, was used to analyze the material.Results: Palliative care places high demands on the competency and experience of district nurses.

The purpose of this study is to gain a better understanding about the police profession's impact on the singular individual, with a focus on roles, regions and emotions. The main question is to understand if and then so, how individuals outside of work will be affected of the profession and professional events. In order to answer this question I carried out six semi-structured in-depth interviews with police officers who worked at the main office in a police region in a midsize city in Sweden. To ensure reliability and allow readers to conduct their own assessments the quotations in this study are anonymous. The analysis of the collected material is based on selected parts of Goffman's theories about dramaturgical perspective as well as selected emotion theories.

The aim of this Master?s Thesis is to study readers and authors of Harry Potter fan fiction, in order to answer the question of why they read and write fan fiction about Harry Potter, and which factors determine what kind of fan fiction stories they read. The empirical material consists of three qualitative interviews with fan fiction readers and authors, and a textual analysis of four internet forums for discussions about Harry Potter and fan fiction. The theoretical background is based on reception theory and reader-response criticism. The results show, that commitment to, and interest in, the source material is an important reason as to why the participants of the study read and write Harry Potter fan fiction.

The aim of this study is to identify the dominating discourse in Swedish newspapers concerning perpetrators who committed sexual offence against children. The study is based on the idea that the media representation play a significant role to the public opinion and awareness of the perpetrators. The study is based upon a selection of 103 articles published between January 2003 and November 2013, taken from four of the biggest daily newspapers in Sweden; Aftonbladet, Dagens Nyheter, Expressen and Svenska Dagbladet. The methodological and theoretical approach in the study has been the one of discourse analysis through which one dominating discourse along with two subsidiary discourses could be identified. The discourse considered to be dominating is the one who presents the perpetrators through the discrepancy between the actions committed and the description of the perpetrator.

The purpose of this study is to find out how clergymen in the Church of Sweden understand their role as pastoral caregivers, in a context of a society that has changed quite a lot during the past decades. The study is based on interviews with four clergymen, two men and two women in the ages of 40-65 with experiences from congregations of different social and geographical kind. The interviews are analyzed in themes. When analyzing the interviews identity and role theory is used as a tool, but also the idea of a postmodern society and metaphors for the different kind of roles a pastoral caregiver can take during counseling.The clergymen meet a broad range of people in counseling, both those who regularly attend church activities and those who are complete strangers. They are all focusing on the needs of the confident.

This essay investigates the function of fictional space and thematics in Line Knutzon?s dramatic works.My main theoretical concept is thematic unity, factors that unite several plays by one author.I have found three major themes: the encounter, identity and childhood, which I study in five of Knutzon?s plays: The Splint In The Heart, The Latest Thing, First You?re Born, The Air Others Breathe and The Time Will Soon Come.I study three aspects of space: fictive space, where the play is set, the characters? inner space and exterior space, that which is outside fictive space: society. Fictive space is shown mainly via dialogue and context.It is evident that the themes, most clearly visible in the five chosen plays, are very important in Line Knutzon?s dramatic works. Most typical is the way she portrays childhood memories, in monologues showing that her characters exist in a ?hole?, in the void between childhood and adulthood.My investigation leads to the conclusion that Knutzon deals with existential matters: there is a kind of constant chaos, within her characters, expressed in actions and thoughts.

The aim of this case study was to investigate the role of leadership and interpersonal relations among staff during implementation of lean at a University Hospital in Sweden. The 15 respondents were leaders and staff members from different wards and clinics, who had started working according to lean principles. One of the methods used was explorative, low structured interviews. Other methods used for gathering information about the case was attending lectures about lean healthcare at the hospital, part-taking in the lean game and reading articles about lean and the implementation in both daily press and on the intranet of the hospital. The results showed that an open and accessible leader that coaches his/her staff and supports their work, helps the staff to develop a lean identity.
