Visualization of Particle In Cell Simulations

A numerical simulation case involving space plasma and the evolution of instabilities that generates very fast electrons, i.e. approximately at half of the speed of light, is used as a test bed for scientific visualisation techniques. A visualisation system was developed to provide interactive real-time animation and visualisation of the simulation results. The work focuses on two themes and the integration of them. The first theme is the storage and management of the large data sets produced.

Läsa, läsa, läsa ? skriva, skriva, skriva

The period of church awakening in Sweden during the first half of the nineteenth century, has had a great influence on the Swedish society. During that time certain persons are to be noticed. Peter Fjellstedt and Peter Wieselgren, priests in the Swedish Church, are among those who were of special importance. But even the British preacher George Scott and later the Swedish layman Carl-Olof Rosenius became aware of the importance of networking. They all felt a call from God to preach a message of redemption and restoration.

"TV-spel är inga konstigheter!": En enkätundersökning om tv-spel på folkbiblioteken

The aim of this bachelor thesis is to investigate the lending of video games at the public libraries in Sweden. The thesis focused around a web survey, which was sent out to all public library directors, as its research material. The results were compared with those found in a master thesis by Olle Berg and Thomas Nyström from 2008. This was done to gain a better understanding of why the libraries provided video games. The other results of the survey were analyzed with a quantitative method.The results indicate that half of the responding libraries provide video games for borrowing.

Samspelet mellan naturbaserade arbetssätt och specialpedagogik: En kritisk studie

AbstractThis essay aims to problematize and illuminate the connection between special-education and nature-based activities. With a theoretical ground that is based upon a sociocultural perspective I consider the information from the field. Through a qualitative and critical perspective I performed individual interviews with five pupils from the sixth school-year in the Swedish elementary-school. I also performed Focus-group interviews with two educators and three teachers in the same school-form. By a Hermeneutical working-method I have found out that the informants in my survey have a common experience that activities performed in nature has a positive effect on learning.

Fel i produktionen : En studie om uppkomna fel i två anläggningsprojekt

AbstractThe purpose of this study was to identify problems that may occur in the execution of a civil engineering project and suggest measures to reduce the risk of errors. The study was conducted in cooperation with a civil engineering company in the Gothenburg area. During two weeks in February 2012, a field study took place on two construction sites where disruption and problems that took more than 15 minutes to correct were noted. During the field study we identified 39 such occurrences in the projects and then these were classified into different categories according to their cause.The two largest categories were "Design" and "Planning", which accounted for half of the errors that were discovered.In the study results were evaluated to decide whether it was possible to detect discrepancies at an earlier stage. The cost to fix an error in the design stage may be significantly less than to correct the problem in production.According to the evaluation, 55% of the errors could have been detected earlier if there was a greater degree of observation for such issues by everyone involved in the project.

Beräkning av energianvändning i svenska småhus

An energy calculation model for Swedish houses   that is fast, flexible and user-friendly has been developed within the   framework of this thesis.  The model   also provides a set of actions which may be investigated in the model based   on savings and payback period. Energy use in a house depends on the technical   conditions, such as building envelope and heating systems, which outdoor   climate the house is exposed to and who lives in the house. Energy use for a   house can be divided into heating, hot water and household electricity. There   are several methods to calculate the energy use of a house. This report   summarizes the methods that may be suitable for a fast and user-friendly   calculation model.

Utveckling av 2D bildanalysmetodik för mätning av  järnmalmsråkulors storlek och form

År 2009 antog IMO en ny resolution som innebär att ett nytt instrument gradvis kommer införas som obligatorisk standardutrustning på fartygsbryggan. Detta system förkortas BNWAS vilket står för Bridge Navigational Watch Alarm System och är kortfattat ett dödmansalarm som syftar till att varna vid otillräcklig aktivitet på bryggan. Detta system har funnits en tid men blir nu obligatoriskt ombord. Detta påverkar arbetssituationen och arbetsmiljön för vakthavande styrmän. Denna studie syftar till att undersöka vad styrmän som arbetar med systemet har för uppfattning och åsikter om systemet.

Primärenergianvändning av passivhus i Sverige : Med fokus på Kvarteret Trettondagen

The building sector accounted for around a fourth of the total energy usage in Sweden in year 2010 (Energimyndigheten, 2012). Therefore it has become very interesting to achieve a lower energy usage in residential buildings. One way to achieve that is to build so called passive houses. By being very well insulated and have low leakage through the walls, they can reduce the energy usage for heating with a substantial amount. The first passive house was built during the 90?s in Germany; and in Sweden the first passive house was built in Gothenburg 2001.

Vad har hänt sedan sexköpslagen trädde i kraft? - En kvalitativ undersökning om attityder till prostitution och samhällets insatser för kvinnor som vill lämna prostitutionen

Since 1999 Sweden have a law that criminalises the person who buys sexual services instead of criminalising the one who is selling, which in most cases is a woman. Seven years has passed since this law took place and in this study we aim to investigate what kind of help the society offer women in Malmö, Sweden, who wishes to step out of prostitution. Our aim with this study is also to look at the attitudes among citizens towards the new law and prostitution. The research is qualitative and all the six persons we interviewed has knowledge about the problems the women are facing when they want to step out of prostitution. To explane and analyse the answers we are using the theory of empowerment, labelling theory, the theory of gender socialisation and Jürgen Habermas theory of the lifeworld.The most significant outcome of this study shows a positive result in regard of the laws effectiveness in diminishing street-prostitution to half of what i t was before the law was put into practice.

Utvecklingssamtal - utifrån elevens perspektiv

My aim with this diploma work is to find out if the students consider development deliberations as a good forum in order to promote their knowledge development or not. I have also examined if the development deliberation is experienced as giving for the pupil or not, what I have been studying from the pupil's perspectives.MethodI have implemented three qualitative interviews with three students from class nine in a compulsory education that lies in Botkyrka municipality. There, I have also an implemented questionnaire survey with two half classes from same class.Materials To my study I have linked literature where research aims himself in on how teachers have worked with development deliberations in the school.Results Students that I have interviewed does consider development deliberations as a knowledgep romoting forum, but most as a forum for clear about study results. The students in the survey consider development deliberations as giving only when the result turns out to bee good.Importance for teachers As each development deliberation is unique, you can not come to a certain implication that all deliberations are experienced in the same way as the result shows. But that can last stakeholder for the teacher is to see how one development deliberation can to be experienced of several students.

Nedbrytning av vägar: Jämförelse mellan axlar med singel- respektive tvillingmontage

When designing roads it?s important to knowwhat loads will bedriven on it. The axles on heavy vehicles can either have super single tires ordual tires which, according to studies, damage the roads differently. The SwedishTransport Administration is developing an understanding for the character ofthese different kinds of axle and tire types on the loads induced on Swedishroads. In this thesis a field study was conducted to determine the distributionbetween axles with super single tires and axles with dual tires on heavy vehicles.A highway, a country road and a national road were investigated during thestudy.

Det borgerliga blocket i medievalrörelsen 2006 : en kvantitativ studie av kvällspressens valbevakning

Purpose/Aim: The purpose of this essay is to examine the ways two Swedish tabloid newspapers portray and describe the non-Socialist parties during the Swedish election of 2006.Material/Method: We have been studying 388 articles about the non-Socialist parties, derived from the two largest tabloid newspapers in Sweden, Aftonbladet and Expressen, during the month before the election. The method for the study is quantitative content analysis.Main results: The main conclusions drawn from this study are that Aftonbladet had twice as much written material about the non-Socialist parties, despite the fact that the paper is traditionally Socialist, while Expressen had consistently larger headlines. Both tabloids function to a higher degree as political actors than arenas for politics. The results are in accordance with earlier research, which shows that the degree of attention the non-Socialist parties acquired as a whole in the 2006 election, is remarkable. More than half of the articles in both tabloids portrayed the non-Socialist parties as a single political actor.
