Dagens grafikkort är uppbyggda av kraftfulla multiprocessorer som gör dom ypperliga för att hantera parallelliserbara problem som skulle ta lång tid att utföra på en vanlig processor, så som exempelvis level-of-detail eller raytracing.Denna rapport presenterar en parallelliserbar level-of-detail algoritm för terränghöjdkartor samt implementerar denna för användning på grafikkort användande Nvidias CUDA API. Algoritmen delar upp den totala höjdkartan i sektioner som ytterligare delas upp i mindre block som beräknas parallellt på grafikkortet. Algoritmen räknar ut vertexpositioner, normaler och texturkoordinater för vardera block och skickar datan till applikationen som skapar vertex och indexbuffertar och renderar sektionerna. Implementationens prestanda och förmåga att reducera trianglar analyseras med två olika sorters culling-metoder; en metod som gallrar trianglar på sektionsnivå och en metod som gallrar på blocknivå.Resultaten visar att det är mycket fördelaktigt att låta grafikkortet hantera level-of-detail beräkningar på detta vis även om minneskopiering över grafikkortsbussen är ett problem, då det tar upp ungefär åttiofem procent av den totala tiden för att hantera en sektion. Beräkningarna i sig tar väldigt lite tid och det finns gott om utrymme för utveckling för att uppnå en så bra fördelningen av trianglar över terrängområdet som möjligt..

This essay is about the Northern Ireland Conflict and the Belfast Agreement. Its focus is on the development in Northern Ireland politics after the implementationof the Agreement which was ratified in a referendum. The essay is a case studywhich analyzes the progress towards an Assembly Government and powersharingbetween the unionists and the nationalists/republicans. The development is analyzed with Robert D. Putnam's theory of Two-Level Games? The essay first analyzes the changes in the unionist society where the opinion towards the agreement has been negative which depends on the concessions made by the unionist.

AbstractReading books to children is often an integral part in preschool activities. The purpose of thisstudy is to investigate how educators think about the educational function of literature inpreschool activities. I have in my study used qualitative interviews with active educators andobservations to answer my questions about why the educator reads to the children, how theeducator thinks about the choice of literature and if the literature can contribute to thechildrens development and if so, how. The knowledge- and research background presentsliterature and previous research done on the subject. The results of my study shows that theeducators have many thoughts about the importance of literature in preschool.

In today?s technological society, there are increasingly less physical demands on the locomotor system. However, despite that notion strength and function in the hand?s complex biomechanical system are in fact both needed to cope with daily life. The grip function is a main function in the hand and is used in many examples of scientific research, for instance when assessing physical health and predicting the probabilities of premature mortality.

This essay examines middle school students? understanding of a text read aloud to them in English and the connection between the degree of listening comprehension and the expected increase of vocabulary throughout middle school. The same listening comprehension test was carried out in grades 4, 5 and 6 in a middle school in order to survey differences in English listening comprehension in regard to the ability to reproduce the content of an oral text. The result shows that there was a progression from level to level when it comes to comprehension and the number of words reproduced and that this progression was most noticeable between grades 4 and 5..

RFID har sedan 80-talet vuxit fram inom industri- och transport-branschen som ett sätt att under-lätta spårning av tillgångar och övervakning av informationsflöden genom logistikkedjan. Tek-nologin har idag många olika applikationsområden och används inom en mängd olika verksam-heter. Item-level Tagging (ILT) är ett sätt att utnyttja tekniken genom att märka enskilda varor för att på så sätt ge dem unika identiteter, vilket erbjuder enorm potential inom detaljhandel. Givet potentialen med tekniken vill vi med vår studie undersöka vilka förutsättningar som kommer att krävas för en ökad användning av ILT och RFID inom detaljhandeln. Detta mål uppnås genom att undersöka de barriärer som tidigare har hindrat en ökad användning samt hur dessa barriärer uppfattas i dagsläget.

The connection between rune stones and churches is a known phenomenon. Unfortunately, very little is known about the previous function of the church sites, and consequently very little is known about what the connection between rune stones and churches means. The purpose of this study is to examine the rune stones connected to churches in the administrative province of Jönköping, in an effort to ascertain their purpose, symbolism and function. The aim is to find out if the rune stones connected to churches were primarily or secondarily placed on the site where the church was later built, and why some rune stones were built into the churches. Further, the inscriptions and iconography of rune stones have been analysed, and also their relation to their immediate surroundings.

The aim of this study was to examine if transformational leadership, transactional leadership, gender, educational level, income and age predict work motivation, referring to Herzberg?s motivation-hygiene theory. According to past research the factors above increase work motivation. The study was brought about with a survey based on the Multi Factor Leadership Questionnaire (MLQ-5X), Herzberg?s motivation-hygiene theory and demographic items.

The aim of this Masters thesis is, with an exploratory stand, to examine the thoughts regarding gender perspective at childrens library service that are expressed from childrens librarians as well as the staff in administrative management. The purpose of the study is to generate ideas for further research and discussion regarding a gender perspective on the childrens library service. A total of eight interviews have been carried out. Three persons at the administrative level and five childrens librarians were interviewed. We also have examined if a gender perspective is expressed in the control documents, from international level to a local level, which the libraries could use when developing and planning their work.

Within the political science literature that deals with the implementation process a central part has long been what is sometimes called the implementation deficit. This means that the effect of a policy decision doesn´t turn out as it was originally intended. The often used explanation is that the policy decisions moves through many levels during its implementation where different actors can change or alter the decision in various degrees. This phenomenon has gradually become more and more attended within the legislative process in the European Union and has been addressed in numerous studies. The purpose of this paper is to examine the implementation of The Habitats Directive, as its embodied in regulatory documents, in the Swedish multi-level system.

The county of Dalarna is at present carrying through a process of digitalization where traditional x-ray film is being replaced with digital detectors. Earlier used methods for dose optimization turned out not being sufficient. This report presents a method to harmonize dose levels between x- ray sites equipped with Fujifilm imaging plate systems. An exposure index, S, related to the dose level of the examination is computed to every x-ray image. S turned out to be inversely proportional to the detector dose used at the examination.

It is mainly high levels of androstenone and skatole in adipose tissue that is the reason behind boar-taint, which is an unpleasant odor and taste from the meat of adult male boars. The purpose of this literature study is to provide an overview of current knowledge about the physioloical functioning of androstenone. There are several studies showing androstenone´s function as a pheromone, and that it is an important part of communication and mating behavior between pigs. Androstenone is produced in the testes of the boar and transported via the bloodstream to the salivary glands where it is excreted with the saliva. Sows sense the pheromone, not via the vomeronasal organ as previously considered, but via the olfactory mucosa.
