The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

Shaping visual stories - content in exhibitions is an essay on how content has been shaped in the two exhibitions "Memento mori" and "Hästen - tyglad, piskad, älskad". The study focuses on how exhibitions can be defined through their content as well as how the exhibitors'different intentions towards the exhibition affect the working process as well as the result. This is put in relation to theoretical models and discussions on ideals in the field of exhibition and what impels these to find an answer to the question: What makes an exhibition?.

The purpose of this essay is to investigate the subject field of male vegans and masculinities through empirical method interviews and narrative analysis. The starting-point for this essay is animal ethics, feminist ethic vegetarianism and theories that suggest that eating meat is one part of the social construction of masculinities. The problem formulation is such as follows:How do male vegans construct masculinity? In an attempt to answer such a question there are three problem formulations:What do male vegans think about the connection between manhood and eating meat?How do male vegans relate to the norms in society?What do male vegans think of stereotype conceptions about vegans?I will come to the conclusion that male vegans think that eating meat, as well as drinking beer, is one part of the social construction of masculinities. Male vegans are aware of norms in the surroundings and the strong attachment of meat normativity in the western culture.

The purpose of this study is to analyze picture books from a gender perspective. The books are found in a book box that the libraries send out to preschools. This study is based on the following questions:How are boys and girls portrayed in picture books?Do the picture books encourage or discourage the principles of equality found in the Curriculum for the Pre-School and the equality work conducted in the preschools?I performed a qualitative text and picture analysis of 12 picture books. I used Maria Nikolajeva and Kajsa Wahlströms schedule of typical masculine and feminine qualities and activities when analysing the picture books.

This essay aims to determine how Muslims are produced in the public domain in Swedishcontemporary time. My study is based on three different materials; Hot mot demokrati ochvärdegrund ? en lägesbild från Malmö investigating Islamist radicalism and extremism inRosengård, articles on Omar Mustafa and his resignation from the Social Democratic Partyand Gun Holmertz article Islamismen får allt större fäste i Hjällbo and the following debate.The method used is discourse analysis as the purpose of the study is to examine howMuslims are produced within the prevailing discourse. Theoretical points have beenPostcolonial theory, Orientalism, Islamophobia and ?us? and ?them?.The results of the study confirm the results of earlier studies, namely that Muslims are not produced in a beneficial way.

The way man divides his thoughts and sorts them into different boxes, is a cognitive activity which works alike for every person. We split peoplesexterior attributes and characteristic qualities into stereotypes or prejudicemind patterns and treat them along those.This study examines through a qualitative method what twelve respondents (six women and six men) between the ages 16-21, think about ?intense? conceptions, which may show stereotype or prejudice ways of thinking. There spondents have been chosen regardless ethnic or economic background andare all enrolled in an upper secondary school located centrally in a Swedish big city.The purpose is to find out if there are any differences between how some young men and some young women spontaneously think in stereotypical orprejudice patterns. The result is interpreted on the basis of the social cognitive perspective and from out of theories about how people create schemes andprototypes to separate individuals and groups from each other.This study suggests that men more easily express their stereotypes and prejudice, while women more often seem to be careful with their stereotypes and prejudice, and end up redefining them.

For centuries Islam and Muslims have been subject to islamophobic attitudes in the west. The purpose with this study was to see into the making of open and closed attitudes against Islam and Muslims from a conflict in southern Thailand, and also to so see if Muslims are portrayed as more violent than the Buddhist groups in the conflict. The aim of the study is also to see if Muslims fall into a violent stereotype. This was studied by looking at five Swedish newspapers coverage of the conflict, during a given time. To be able to look into this, two theories will be used, the first one is the Runnymede Trust theory, which is about open and closed attitudes against Islam and Muslims.

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

SUMMARY The purpose of this study was to explore how nurses in the emergency department experience and cope with stress in their workplace. The study had a qualitative, descriptive approach and was based on nine individual, semi-structured interviews. They were then processed using content analysis. The content analysis of interviews resulted in two categories, "the nurse's experience of stress," "the nurses coping with stress." Together, the categories highlighted how nurses experienced stress during and after their shifts. The study showed clearly that all nurses experienced and coped with stress in their daily work activities..The authors noticed that stressful time for the nurses were repeated at each session and were similar in character.

Audiological rehabilitation is a complex process and can involve medical, educational, psychological, social and technical proceedings. The audiologist's part in this process is essential. The purpose of the study was twofold: to describe the audiologist's working process and to explore patient records written by audiologists according to structure, content and comprehensiveness. Method. Out of rules and regulations, code of ethics and literature concerning audiological rehabilitation from the audiologist's point of view, a model for the audiologist's working process was developed.

The increasing oil prices during the last years have made it profitable to use cereal grains as a fuel. When compared with wood, cereals contain higher amounts of Cl, S and ash. The Cl and S content makes the gases from cereal combustion more corrosive than gases from wood combustion. The goal of this master thesis was to find out the variation of Cl, S and ash content for oat grain grown under different conditions. Oats was chosen because in Sweden it's considered as the cereal with the best fuel qualities.

Today there is a large consensus about the importance of Swedish schools providingconditions enabling students to develop the ability to manage and learn through information technologies (IT). The goal of this study was to describe and examine how national education goals for the use of IT transformed into municipal IT-strategies for the school. A content analysis was conducted of thirty-eight municipal IT-strategies collected from Swedish municipal websites on the Internet. The content in the municipal IT-strategies was compared with the content in both the Swedish education act and the national curriculum. The results showed that the content in the Swedish education act and the national curriculum in fact was translated into municipal IT strategies, but that the range of strategies concerning technology, pedagogy and content in relation to IT was broad.

I och med införandet av BIM-metodiken inom byggbranschen, har flera frågor fötts kring reformationen av arbetsmetodiken inom projekteringsprocessen. En av dessa är frågan om content; grafik - och informationsinnehållet i en BIM-modell.  Rapportens syfte har varit att, via analys av befintliga contenthanteringstrategier, frambringa rekommendationer för utformande av konsekventa arbetsmetodiker inom Revit-projekt. Mål- sättningen har varit att rekommendationerna skall bidra till förstärkning och vidareutveckling av ett företags hantering av Revit-content.  Arbetet inleddes med en serie intervjuer på arkitektföretaget Tengboms Stockholmskontor. Intervjuerna utfördes med representanter för olika Revit-baserade projekt. Av dessa valdes fyra projekt ut till mer detaljerade fallstudier, där syftet var att kartlägga vilka strategier Tengbom tillämpat i sina Revit-projekt. Parallellt med intervjuerna, utfördes en litteraturstudie där information om befintliga contenthanteringsstrategier inom övriga företag och organisationer, kunde förvärvas och analyseras. Resultatet av fallstudierna på Tengbom jämfördes med de teorier som framkommit via litteraturstudien.

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.
