To render outdoor scenes with lots of vegetation in real time is a big challenge. This problem has important applications in the areas of visualization and simulation. Some progress has been made the last years, but a previously unsolved difficulty has been to combine high rendering quality with abundant variation in scenes. I present a method to mathematically generate and render vegetation in real time, with implementation in the scene graph Gizmo3D. The most important quality of the method is its ability to render scenes with many unique specimens with very low aliasing.

Background: Each year approximately 30 000 people suffer from stroke in Sweden, often with substantial mental and physical consequences. Those who suffered from stroke handled the situation by mourning what they had lost and by accepting their changed body and life situation. For those who provide care for people who has suffered a stroke help and support was required. The caring science perspective was based upon caring and suffering. Aim: The purpose of this study was to describe family caregivers? experiences of caring for persons who had suffered a stroke.

AbstractThe employer is obliged to initiate negotiations with the union organization to which the employer is bound by a collective agreement. This applies both to decisions which imply a substantial change in workplace operations or employment conditions of the individual employee. In case law this obligation has been very extensive through all cases that have been up in the Swedish Labor court. Due to this fact the employer?s duty to negotiate has been interpreted very broadly.

The purpose of this study is to get an understanding about how municipalities in Sweden integrate climate-change into the social planning; especially the risk of flooding. To get a good picture of the planning process, background about the following are given; flooding, social planning and protective measures that can be taken against flooding. Three municipalities in the south of Sweden is studied; Halmstad, Vellinge and Kristianstad. They have in their work progressed differently and Kristianstad is the municipality that already has taken measures to protect themselves against flooding. The other two have only started to plan for the future threat.

The purpose of this study is to determine whether or not there has been a change in the use of democratic values in textbooks in social science for classes 4-6. The focus lies on democratic values from two different theoretical perspectives, Dahl?s theory of democracy and Habermas deliberative democracy. The method used is a text analysis based on a model made by Lennart Hellspong. The material we?ve analysed consists of four textbooks in social science from different decades, with a range from 1981 until today.

Grid codes are becoming more demanding on power generating units due to the factthat the complexity of the power grid is increasing. The penetration of wind powerhas grown over the last years and it is clear that wind farms need to be addressedwith the same type of grid codes as conventional generation units. There is howeveran undeniable difference between the technology in conventional synchronousgeneration units, and the asynchronous generation units in wind farms.This thesis has reviewed the current grid code in Sweden and compared it to the newcode proposed by ENTSO-E, ?the Requirements for Generators?, in the aspect ofwind farms with an installed power of 30 MW or more. The comparison has beencomplemented by an analysis of how wind farms of two different technologies(Doubly fed induction generators and full power converters) can meet therequirements and technical proposals have been given on how to be able to meetcompliance with the new grid codes.The Requirements for Generators contains many non-exhaustive and optionalrequirements, because of this it has been difficult to, at this stage, exactly point outthe technical impact on the grid connection of future wind farms in Sweden.

Syfte: Syftet med vår uppsats är att ta reda på hur Landstinget Blekinge arbetar med den generationsväxling som pågår och det svaga intresset hos den yngre generationen samt hur det faktiska arbetet med att vara en attraktiv arbetsgivare ser ut, både inom och utanför organisationen, för att undvika en brist på arbetskraft. Vidare vill vi även undersöka om den bild teorier framställer av den nya generationen skiljer sig mot uppfattningen som chefer inom Landstinget Blekinges har. Syftet är också att se hur väl Landstinget Blekinge arbetar med att bli en attraktiv arbetsgivare i jämförelse med SKL:s bild och därmed bidra till ökad medvetenhet kring arbetet med generationsväxlingen samt de utmaningar och svårigheter som kan finnas i samband med den. Metod: Undersökningen är baserad på en kvalitativ, abduktiv metod och semistrukturerade intervjuer med tre personalchefer, en förvaltningschef samt kommunikationsdirektören inom Landstinget Blekinge. Resultat: Våra resultat visar att Landstinget Blekinge har en skriftlig varumärkesstrategi för vad som behöver göras.

This essay is a study that takes interest in technical and technological change essential to philosophy of science. What is shown is the importance of an active attitude towards this change, by the articulation of the question: Does technical development lead to new ontological questions for science? - and by the answer that such questions do appear.It is clear that passive assumptions in this matter might prohibit science in the proceeding search for truth.By examples of ways in which technical development helps and challenges science, it is concluded that scrutiny of the relationship between technical development and ontological suppositions and hypotheses within science is well motivated..

Metod/Method: Semistrukturerade intervjuer har genomförts med kommunchefen, personalchefen, fyra medarbetare och en facklig representant i Sala kommun. Materialet från intervjuerna analyserades sedan bland annat med hjälp av två av Morgans organisationsmetaforer, Kotters 8 steg, agil projektledning och Derbys tidigare forskning inom området./ Semi-structured interviews have been conducted with the local head of government, the human resource manager, four employees and a union member in Sala kommun. The material from the interviews was then analyzed with help from Morgans organizational metaphors, Kotters 8 step, agile project management and Derbys earlier research on the area. Slutsatser/Results: En organisationsförändring enligt agil projektledning innebar att de teoretiska rekommendationerna för hur en organisationsförändring ska genomföras följdes. Att personalen gjordes delaktig i förändringen gjorde att motståndet mot organisationsförändringen kunde minimeras vilket var den största fördelen. De nackdelar som fanns med en agil projektledning vid organisationsförändringen var i princip obefintliga i jämförelse med fördelarna./ Organizational change according to agile project management made sure that the presented theoretical recommendations on how to succeed with organizational change were followed.

This report describes a comparative study of the change in grading system in the year of 1995 and the coming year of 2012. The objective is to analyze and compare the political debate from two Swedish parties, the Social democrats and the Moderates, from a number of the parties political periodicals. Futher the objective is to show, from the periodicals debate, what approach to knowledge the parties are presenting. The theoretical base of this study is rooted in the political background of grading system and in literature defining different theories about knowledge and approach to knowledge. The investigation is qualitative and the main research method is text analysis.The conclusions is that the parties overall stood their ground and kept their opinions throughout the two debates and the change in grade systems.

This paper is a study of some of the mathematics textbooks that were used in Swedish public schools from 1842 to the present. During this period several revisions of the curriculum took place and led to a change of contents in the various books. The first part is a description of the books chosen and highlights from each are given and compared with the corresponding curriculum. Also social and political change and the role of men and women can be studied in the examples presented. A comparison between similar topics and how they were accounted for in the older versus the newer books follows suite.

The essay investigates juvenile offenders experiences of the sanction ?ungdomstjänst? and how it may change attitudes towards committing criminal acts. The essay introduces qualitative interviews with four juvenile offenders, which have all executed ?ungdomstjänst?. The juveniles experiences of features that can be a part of the attitude change have been analyzed with a model of the motivation process, called ?Fyra F?, and four elements of persuading, which can affect an attitude change.

The EU has for a long time had a special relationship with its former colonies in Africa Caribbean and the Pacific, called the ACP?countries. This relationship is about to change radically with the new partnership agreement signed in June 2000 in Cotonou. This essay aims to study the EU ?ACP Partnership Agreement from the perspectives of two different theories: The liberalist, free-trade policy theory and the nationalist/regionalist, protectionist theory.

This study has been executed at the Public Employment Office, an institution that has beensubject for much debate during the last couple of years.

This study examines one of the Public Employment Offices that are included in apilot project that aims to improve and develop work methods with the objective to become amore service minded organization. From this starting point we have investigated which effect thisorganizational change has had on the employee within this organization and within the pilotproject. In addition we investigate whether attitudes of the unemployed has an effect on thestaff´s work situation.

Den Allmänna Förklaringen om mänskliga rättigheter fastställer att alla människor är födda fria och med lika värde och rättigheter, oavsett ras, hudfärg eller annan åtskillnad. Den fastställer även att de har rätt till bland annat liv, frihet och personlig säkerhet. De rättigheter som hanteras i denna förklaring kan delas upp i två kategorier: medborgerliga och politiska rättigheter samt ekonomiska, sociala och kulturella rättigheter. Många omnämner dem även som två ?generationer?, vilka vuxit fram utifrån olika revolutioner där människor har kämpat för sina rättigheter.
