Under de senaste åren har en ny trend inom spelindustrin uppstått då en stor del av spelen har gåtttillbaka till de tvådimensionella miljöerna som var vanligare i tv-spelens barndom, detta tack vareatt mobiltelefoner och deras spel har tagit allt större plats på marknaden och de är oftatvådimensionella på grund av sin begränsade hårdvara. De tvådimensionella spelen har enligttradition inte haft någon dynamisk ljussättning, utan de har bestått utav färdig grafik medförutbestämda intensiteter vilket gör att spelen kan se platta ut.Men inom andra områden av spelindustrin, framförallt tredimensionella spel, har utvecklingen avdynamiska ljussättningsmetoder kommit långt. Problemet med dessa metoder är att de kräverobjektens normaler, vilka normalt inte finns tillgängligt i tvådimensionella bilder.Idag är mobiltelefonerna kraftfulla och klarar av mycket tyngre beräkningar än vad de gjorde förbara några år sedan. Därför undersökte vi möjligheten att implementera dynamisk ljussättning i etttvådimensionellt spel på androidbaserade mobiltelefoner. För att genomföra detta krävdes också attvi undersökte metoder för att generera normaler för tvådimensionell grafik.För att ett fullständigt spel skulle kunna skapas så implementerades också saker somkollisionshantering, artificiell intelligens och procedurell generering av banor..

The aim of the Master?s Thesis work is to study and develop algorithms for autonomous travel of a UGV (Unmanned Ground Vehicle). A vehicle for the mounting of sensors has been constructed in order to perform the work. Since the UGV is to be used outdoor in urban areas, GPS can be used. To improve precision and robustness, inertial navigation is used in addition to GPS, since GPS reception is likely to be diminished in such areas.

In this paper, the legal situation regarding freedom of expression versus the duty of loyalty is investigated, this in a context where an employee makes critical statements about his employer through social media.The duty of loyalty is a part of all employment relationships and it follows implicit from the contract regardless of whether it is specified in it or not. This duty means that an employee is required to put the employer's interests before his own and avoid all situations that end up in collision of the duties. The employee may no t either act in such a way that is intended to harm the employer. This means that the employee must be even off duty careful not to appear disloyal to the employer. This may lead to that a status update on Facebook, even when made on the employee's free time, can be regarded as disloyal conduct, with the dismissal or disciplinary action as a result.Case law states that the point of departure regarding criticizing the employer must be that the employee has an extensive such a possibility to that, without that being considered as disloyal conduct.

AbstractIn Sweden all persons under the age of 18 are considered children. The age when it is possible to be held responsible for a criminal act, and therefor convicted in court, is 15. Society?s and, perhaps first and foremost, the authority?s attitude towards juvenile crime is that they should not be equal adults in the process within criminal law. Because children are considered essential for the society of tomorrow, it is important to pay extra attention to crimes committed by juveniles.

Med fler än en miljon omkomna i trafikolyckor världen över varje år är trafiksäkerhet ett ständigt aktuellt område. Studier på deprimerade patienter har visat att negativ sinnesstämning medför försämrad körförmåga. Dessa effekter är i hög grad outforskade och det är därför viktigt att undersöka om de förekommer även vid en mildare grad av nedstämdhet, så kallad dysfori, vilket i så fall skulle innebära att negativ sinnesstämning i likhet med trötthet och alkoholpåverkan utgör en allvarlig trafikfara. För att bättre förstå hur sinnesstämning påverkar körförmåga är det dock också relevant att undersöka om dysfori kan bidra till riskkompensation, det fenomen som inträffar när människor kompenserar för säkerhetsförändringar genom ett förändrat riskbeteende. I denna uppsats beskrivs en del av en körsimulatorstudie kring dysfori och bilkörning, där syftet var att undersöka om dysfori kan vara en orsak till riskkompensation.

Productivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) was studied on 12 sites in coastal areas of northern Sweden. On each site, sample plots were placed in adjacent Norway spruce and Scots pine stands with similar ages in between. Basal area, tree height, Site Index, volume production, simulated maximum mean annual increment (MAImax) and tree vitality were compared for the two species. Average basal area at the time of measurement was 30.4% larger for Scots pine stands than for Norway spruce stands. The difference between the two species in basal area increment during the last 10 years was related to stand age.

Att vistas på gång- och cykelbanor kan vara en situation som upplevs som otrygg av de oskyddade trafikanterna som delar på detta utrymme. Samexistens och hänsyn till medtrafikanter är av vikt för att minska konflikter och skador som uppstår i denna miljö.En anledning till konflikter mellan fotgängare och cyklister är den höga hastigheten som cyklister kan färdas i. Denna hastighet skapar otrygghet bland fotgängare samt hos de cyklister som färdas i ett långsammare tempo. Otryggheten, beteende hos de båda trafikantgrupperna samt hastigheten leder i vissa fall till konflikter med kollisioner och personskador som följd. Att separera gång- och cykeltrafiken minskar till viss del konflikterna mellan dessa två grupper, men konflikten mellan cyklister som färdas fort och de cyklister som färdas långsamt kvarstår samt att otryggheten till viss del kvarstår hos fotgängarna, speciellt i de fall separeringen enbart skett med färgmarkering.

The VAT Directive (2006/112/EC) does not regulate Member States? opportunities to intervene against tax evasion. The European Court of Justice has clarified the situation in case C-255/02 Halifax. This case establish that the universal principle against the abuse of rights applies to VAT, which means that Member States have the opportunity to redefine transactions not involving a breach of law but nevertheless goes past what the legislature envisaged at the introduction of the provision.A debate has risen as to whether the principle against the abuse of rights is equally ap-plicable in Swedish domestic law on VAT. The administrative court of appeal in Go-thenburg, Case No.

Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.

Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils. The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after direct seeding and planting. The study also attempts to simulate growth until first thinning.

This essay is an introduction to the intentions and purposes of the british play writer Sarah Kane (1971-1999). Her own voice is presented both via quotations linked to her work and by an explanation of her connections to the surrealist poet and actor Antonin Artaud. The main focus is on Kane?s second play, Phaedra?s Love, first performed in 1996. The play is analyzed in co-relation to La volonté de savoir, the first volume in Michel Foucault?s trilogy Histoire de la sexualité.

In the Kolmården area, northeast of Norrköping in south-central Sweden, it was discovered that shoots of spruce Picea abies, plants to a seemingly large extent had been browsed by deer. The area inhabits a dense red deer population, alongside with moose and roe deer, and red deer is thus suspected to cause the damage. The main purposes of this study are, however, to estimate the extent of the shoot-damage and to investigate what factors that may affect the browsing of shoots. For each stand information was recorded about the age of the plants, area for the stand, height over the sea for the stand, site productivity, type of plants and stand-history. The study was done in three areas: Simonstorp, Stavsjö and Valinge. At Simonstorp and Stavsjö, respectively, 10 stands were chosen for study and on Valinge six stands. In each stand, 10 plots were sampled.

The effects of Reindeer mechanical damages on the planted regeneration of Pinus sylvestris and Pinus contorta. Semi-domesticated reindeer can damage young trees. In late winter reindeer rub their antlers against young trees. The aim of this study was to quantify those damages. This study covered planted objects from three different areas in northeastern Sweden.

Title: From inspectors to guides: how citizen journalism and participatory cultureaffect the professional identity of Swedish journalists (Swedish title: Från granskaretill guide: om medborgarjournalistikens och deltagarkulturens påverkan på svenskajournalisters professionella identitet).Number of pages: 44 (48 including enclosures).Authors: Towe Bengtsson and Matilda Källén.Tutor: Amelie Hössjer.Course: Media and Communication Studies C.Period: Fall 2011.University: Division of Media and Communication, Department of Informatics andMedia, Uppsala University.Purpose/Aim: The goal of this paper was to answer how citizen journalism andparticipatory journalism as well as an increasing range of information today haveaffected the professional identity and professional lives of journalists. In addition tothis, study how journalists today respond to these changes.Material/Method: The study is based on Deuze?s theories about journalistic ideals,Jenkins? theories about convergence culture, and on theories about professionalizationand de-professionalization based on Nygren, Wiik and Torstendahl?s theories. Thestudy is based on eight interviews with professional journalists, four employedjournalists and four freelance journalists. The results are analysed based on a broadtheoretical framework.Main results: The results of this survey show that the role of the professionaljournalist is extremely complex, with a strong ideological basis that fundamentallyinfluences the journalist's view of the profession and of him- or herself.
