WPF is a newly introduced graphical system that is a part of Microsoft?s .NET Framework. This report will evaluate WPF and its features. A comparison is made mainly towards the previous version of .NET which is .NET 2.0. The work is partly theoretical and partly implementational.

Three-dimensional computer graphics enjoys a wide range of applications of which games and movies are only few examples. By incorporating three-dimensional computer graphics in to a simulator the simulator is able to provide the operator with visual feedback during a simulation. Simulators come in many different flavors where flight and radar simulators are two types in which three-dimensional rendering of large terrains constitutes a central component.Ericsson Microwave Systems (EMW) in Skövde is searching for an algorithm that (a) can handle terrain data that is larger than physical memory and (b) has an adjustable error metric that can be used to reduce terrain detail level if an increase in load on other critical parts of the system is observed. The aim of this paper is to identify and evaluate existing algorithms for terrain rendering in order to find those that meet EMW: s requirements. The objectives are to (i) perform a literature survey over existing algorithms, (ii) implement these algorithms and (iii) develop a test environment in which these algorithms can be evaluated form a performance perspective.The literature survey revealed that the algorithm developed by Lindstrom and Pascucci (2001) is the only algorithm of those examined that succeeded to fulfill the requirements without modifications or extra software.

Reading difficulties is the most common learning difficulty in the western world and it is common that people with reading disabilities also exhibit arithmetic difficulties. Different theories about the cause of the relationship exists, one theory describes the importance of good phonological ability in reading as well as in arithmetic, while another theory describes the importance of a reliable number system and that only a subgroup of students with reading disabilities also have difficulties with arithmetic. The purpose of this study is to investigate how students with reading difficulties (RD), without any known mathematical difficulties, perform on mathematical tasks relative to a control group. The study was theoretically grounded on the Triple code model (Dehaene, 1992), which is a model for numerical information processing that describes how various numerical and arithmetic tasks are processed through three distinct representation systems in the brain, a verbal and a visual representation system and a quantity system. Reading skills, phonological skills, arithmetic skills and number processing skills were examined in 61 students through a variety of tests.

Syftet med denna studie har varit att öka förståelsen för hur konflikter hanteras inom horisontella organisationer. Detta genom att studera hur Spotify upplever konflikters påverkan samt hur konflikter hanteras inom organisationen. Studien har utifrån en fenomenologisk ansats studerat konflikter och hantering av konflikter ur ett ledarskapsperspektiv. Datainsamlingsmetoden har varit semi-strukturerade intervjuer.I resultatet framkommer det att konflikter upplevs som positivt för individers och Spotifys utveckling då konflikter upplevs bidra till nytänkande och utveckling. Studien visar på att organisationer genom konstruktiv konflikthantering kan utvecklas.

AbstraktUndersökningens syfte är att undersöka vilka faktorer som motiverar anställda att stanna kvar på sin arbetsplats och se vilken roll trivsel och arbetsmotivation spelar i sammanhanget. I förlängningen vill vi undersöka hur företaget kan arbeta för att behålla sina anställda.Följande frågeställningar utgör studiens röda tråd: Vilka motiv uppger anställda som viktiga för att trivas på sin arbetsplats? Vilka faktorer skapar arbetsmotivation bland de anställda? Hur kan trivsel och arbetsmotivation tänkas påverka de anställda till att stanna kvar på arbetsplatsen?För att få svar på dessa frågor har åtta personer intervjuats på ett företag. Tillvägagångssättet är kvalitativt. Resultatet visar att: om respondenterna får utmanande arbetsuppgifter med variation ökar drivkraften till arbete; en avklarad arbetsuppgift ger även den tillfredsställelse; utveckling och ansvar spelar stor roll; kompetensutveckling och utbildning stärker individen i sin yrkesroll; flexibilitet och självbestämmande är viktiga faktorer för de anställdas trivsel och motivation; god stämning har avgörande betydelse för den anställdes fortsatta trivsel/vantrivsel; feedback är motivationsskapande men om det saknas inträder vantrivsel vilket kan få den anställde att söka sig bort..

Bakgrund: Motivation är något som finns hos alla människor, den kan bestå av både inre och yttre motivation. Inre motivation är något en människa får när hen gör något intressant och meningsfullt. En yttre motivation nås när något ges tillbaka efter den handling som utförts. Dagens sjuksköterskor möts av många hinder i form av hög arbetsbelastning, låga löner och stressiga miljöer vilket leder till att sjuksköterskor väljer att lämna vården. Å andra sidan väljer ändå en stor del sjuksköterskor att jobba kvar eftersom de fortfarande känner motivation.

This bachelor thesis is a study in the analysis of paintings with focus on the technical exami-nation within the framework of ATSR. ATSR is a methodology based on an interdisciplinary study with the aim of putting the object in its context.The study is based on questions concerning which information the object can give, how we access this information and how it can be put in a larger context. My thesis contains three major parts. First a short overview of methods of analysis used in this form of investigation is presented. This is followed by two case studies which exemplify the technical investigation.

This thesis work is intended to analyze whether the municipalities has a need for the new technology of mobile mapping.Mobile mapping consists of the technologies of laser scanning, photographing and positioning of streets and roads in city environment and in the countryside. When these technologies are operating together a georeferenced three-dimensional image model is created, which has specific coordinates that states its position on the surface of the earth. Thanks to the laser scanning process even measuring can be performed in this model.The municipal sector consists of many different departments which use visual spatial information. These departments are an interesting target group for this system. Specific departments within the municipal sector, which we considered were the most suitable, have been selected.

Due to political decisions regarding the Swedish school, public and independent schools booth face the need topromote themselves in the quest for new pupils. This study aims to, from a communications perspective, examine how four selected upper secondary schools address their target audience; the pupils?to?be, on their homepages. Additionally, I intend to investigate whether, and if so, how, said addressing can be connected to the different target groups applying to the schools in question.The questions asked in this study regard the way in which the selected schools describe themselves on their homepage; how do they use the textual and visual content to address their audience, and can there be disagreement between the meaning of the text and that of the image? To answer these questions, I use a theoretical base made out of visual communication and semiotic as well as rhetorical analyses.The methodological procedure is a qualitative approach on the matter, allowing me to understand the ?what? of the content on the homepages, as well as the ?how? it?s being communicated.

The problem of separating a non-rectangular foreground image from a background image is a classical problem in image processing and analysis, known as matting or keying. A common example is a film frame where an actor is extracted from the background to later be placed on a different background. Compositing of these objects against a new background is one of the most common operations in the creation of visual effects. When the original background is of non-constant color the matting becomes an under determined problem, for which a unique solution cannot be found. This thesis describes a framework for computing mattes from images with backgrounds of non-constant color, using Bayesian statistics.

The Youth Outcome Questionnaire 2.0 Self Report (Y-OQ 2.0 SR) has been implemented in residential treatment centre in the Municipality of Örebro as a result of the strive for a more evidence-based working approach within social work. This study aims to examine how personnel and adolescents describe the treatment/counseling and support and the application of the Y-OQ 2.0 SR in the units. The questions cover the values the personnel and adolescents ascribe to the application of the Y-OQ 2.0 SR, if the result from Y-OQ 2.0 SR is congruent with how the adolescents have been affected during the placement, which obstacles and/or possibilities emerge in the management of the instrument and if there are any indications that the Y-OQ 2.0 SR is advantageous or disadvantageous in the treatment process. The study has a qualitative approach; four interviews were carried out with adolescents and five with personnel. The result shows that structure is an important component in attaining a change in behaviour.

The mistakes and failures on the roof are noticed during inspection of the construction, many of the commentaries are recurring. A contractor should only need to get a commentary once and then learn from the mistake. It has in this study been brought to light that the solution is not to tell the contractors to "stop slattern", it is more complicated than that. Today, the biggest problems are found in leadership, communication, feedback of experience and that the entrepreneurs take too little responsibility.To minimize the amount of commentaries all contractors need to work with a clearer leadership where the leader is both respected and appreciated. The leader must in an effective way be able to convey all the information to all employees.

The purpose of the project was to make a system that could extract data from a mobile eye tracker and make it comparable with data from visual stimuli. The produced system was programmed in Java and provided all the necessary parts that were required to achieve the purpose. This provides a foundation for further research to determine whether the eye tracker is sufficiently accurate to diagnose Parkinson?s disease..

Traditionellt är medarbetarsamtalet till sin form ett organiserat och planerat samtal mellan chef och medarbetare, oftast i syfte att kartlägga behov, krav, verksamhetsmål och förståelse hos medarbetaren. Sedan 1980-talet har det forskats mycket om medarbetarsamtal i Sverige, oftast med utgångspunkt i medarbetarens upplevelse. Vi menar därmed att det saknas ett perspektiv, nämligen det på chefen och dennes utveckling av sitt ledarskap. Vi har därför valt att analysera medarbetarsamtalet som en förutsättning för ledarskapsutveckling. Eftersom det inte finns mycket forskning om denna omvända syn på medarbetarsamtalet, har vi valt att med ett explorativt förhållningssätt genomföra en kvalitativ intervjustudie med fem chefer som i sitt arbete utför medarbetarsamtal.

Denna uppsats handlar om modeföretags online visual merchandising ur ett konsumentperspektiv. Vi har undersökt vad konsumenter anser vara viktiga aspekter ur perspektiven miljö, navigering och produktpresentation för att de ska finna en e-handelssida attraktiv. Tidigare forskning visar att för en kund ska genomföra ett lyckat köp på ett modeföretags e-handelssida krävs det att den virtuella miljön är väl utformad. Dock fann vi ett gap i tidigare forskningen där teorierna inte var prövade utifrån ett konsumentperspektiv. Målet var därför att skapa en modell, som tog hänsyn till konsumentens åsikter, och som modeföretagen kan ha användning för vid utformning av sin virtuella miljö.
