This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

There are many barriers and obstacles that need to be removed to make the urban environment more accessible for people with disabilities. There are currently no adequate tools for urban planners to assess and address these obstacles. Geographical Information Systems (GIS) provide powerful methods for the visualization and analysis of spatial data, including the kind of data important in studies of accessibility. This study suggests a method urban planners can use to identify accessibility obstacles and to propose future actions to fix them.A literature review was conducted to find out what has been done and what is new regarding the accessibility issues. Different methods were evaluated which in turn led to the construction of a multi-step analytical strategy.

This Master?s thesis explores three contemporary Swedish poets? ? Lars Mikael Raattamaa, Anna Hallberg and Johan Jönson ? understanding of their work as a political activity. By using Jonathan Culler?s theory on literary competence and literary conventions as a theoretical tool for an idea analysis, the three poets' arguments for or against certain literary techniques, and their ideas about readers and reading, are explored and discussed. In what ways are established literary methods questioned by the three poets? In what ways are established theories on readers and reading questioned? In what way can their poetic work be regarded as political? As a background, the debate about poetry in Swedish newspapers and literary magazines is presented, as well as the common focus on readers and reading in social sciences and in humanities and arts.

The aim of this study is to investigate ordinary readers' evaluation of quality in literature. The main issue is which criteria ordinary grown-up readers use when they are defining their likes and dislikes in literature. The analysis is based upon qualitative interviews with six readers, two men and four women, between 21 and 59 years of age. The study is hermeneutic. Since theoretical works concerning evaluation of literature among ordinary readers are sparse, the philosopher of arts and religion Hugo A.

Computational thinking was brought to the forefront in 2006 by Jeannette Wing. Computational thinking is a problem solving method that uses computer science techniques.The thesis is analyzing computational thinking and how it could be applied to graph theory. Characteristics and main fields from computational thinking is being analysed. This analysis is applied to graph theory to see the potential in developing a proposal for how an exercise can look for an introductory course in discrete data types. Only basic knowledge of graphs is required to perform the exercise.

This master thesis is about the production of the record ?Brutus? with the band ?Trilobit?. Trilobit consists of the three musicians, myself, Stina Hellberg Agback on pedal harp, Simon Sva?rd on guitar and Karl Jansson on drums.During the production, I have analyzed different aspects of my own musicality and also the role of the pedal harp in jazz. I have found techniques that have simplified chromatic movements on the pedal harp, and also techniques that has developed the rhythmical aspect of my improvisation.I have also looked into my process in improvising and composing and developed new aspects, many thanks to the close collaboration with Simon Sva?rd..

Even though the American author H.P. Lovecraft (1890-1937) has been praised as one of the most influential writers of horror literature in the 20th century, his style of writing has occasionally been criticized. Lovecraft was using a writing style based on strict scientific language, where the human condition and existence are irrelevant in the narrative. This includes less focus on character development and more on the importance of atmosphere and environments. I am presenting narratological analyzes of what is often considered to be three of Lovecraft?s ?greatest works?: ?The Call of Cthulhu?, At the Mountains of Madness, and ?The Shadow over Innsmouth.? These analyzes are used to highlight Lovecraft?s science-oriented language and narratological techniques, with the focus of studying what methods Lovecraft was using to give his works and his readers a sense of dread, hopelessness, and an alien atmosphere.

The objective of this thesis was to study how parents of adult drug addicts experience their contact with the social welfare office, what elements affected the parents degree of satisfaction with the contact with the social welfare office, and whether the contact meant any help for them. Six parents of adult drug addicts were interviewed..

The purpose of this study was to examine and illustrate whether employed social workers, working with supplementary benefits at a social service office, felt stressed. If so was the case, we wanted to investigate if this stress that they felt had any effect on their clients. This study was based on eight qualitative interviews, of which four was with social workers and four was with clients. For a better understanding of our results we used Karasek & Theorells demand-control-support model.The study reveals that the social workers do feel stressed, but they only do so in periods. They declare that they would like to have more time for their work assignments, the meetings with the clients in particulate.

The information flow of today is endless and the advances in information technology astounding. In today's information society it is of utmost importance not only to be able to find the right information but also to evaluate the information. The expression ?information literacy? is not a new one but it has never been as pertinent and essential as today. Information literacy is however not something which is easily and swiftly achieved.Swedish youth education is based on problem based learning in which the students are expected to research for material, evaluate their finds and use their skills to produce a good written or oral presentation.

My purpose with this study was partly to examine how some Swedish science teachers teach and their knowledge of the science curriculum, and how this affects their teaching. I also aimed to compare the Swedish and Irish science curriculum. The method I undertook to achieve this study was to carry out six interviews with science teachers in Sweden. I also completed a text analyse of both the Swedish & Irish science curriculum. The results of the interviews showed that the teachers think the curriculum is important but they do not always keep to it.

The adolescents noticed a change in them selves after their stay in Ungbo. The social workers were positive to Ungbo but they felt a need for others resembling activities in Kalmar..

This Master´s thesis examines the conceptual ideas of science fiction and science fiction fandom produced in the Swedish fanzine Science Fiction Forum (1960-) between the years 1960 and 1980. Science Fiction Forum was and still is a fanzine published by Skandinavisk Förening för Science Fiction (Scandinavian Science Fiction Club). Both the club and the fanzine are a part of the phenomenon called fandom.A fandom is a collective of people called fans who form a community by sharing a special interest in a special object. The fanzine is one of the many material products produced by fans within a certain fandom. Science Fiction Forum and Skandinavisk Förening för Science Fiction were founded in 1959 and are a part of swedish science fiction fandom, where the object of fandom is literary science fiction..The primary focus of this thesis is the meta discussion on science fiction and science fiction fandom in Science Fiction Forum.

Museums are a part of the cultural sector that over the last couple of years had to compete with the steadily growing consumption of spectacles. New techniques to attract and amaze the visitors have evolved. Living History Museums has developed a method to simulate past times by building up an environment with reconstructions. History is a non-definite science, there will never be an exact answer to how it really was, for example during the Middle Ages.This essay deals with the difference between reconstructions and authentic artefacts and how they build up an illusion of the past. In what sense does it matter if the artefacts are genuine or not? How do these museums deal with anachronistic phenomena from today's modern world in the historic environment? Additionally I discuss whether or not these reconstructions - of environment, buildings and personal characters - have any influence on the historic narrative given by the museum.
