Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

In the expansion rate of the national as well as the international market, the importance of trademark has been given a central matter. The definition of what can be considered a trademark has been widened. Today?s trademark law defines a trademark as something that can be graphically reproduced. Trademarks can there for contain names, words, numbers, letters or the shape of the goods itself or the packaging.

The purpose of this report is to create and develop a model that streamlines and helps the innovationprocess of an idea owner and also in the development of ideas.This model should be able to apply for workshops and in innovation advice or business devlopment. I used the qualitative method in my essay just to get a maximum clear data collection, where the seven respondents were included in the interviews. However, much of the information retrieved from the theory books and research/science articles, in order to answer the research/Sceince question in the best possible way.

För att kunna nå politiskt uppsatta nationella klimatmål för 2050 krävs en ökad användning av järnväg. Samtidigt belastas järnvägen mer och mer eftersom varor och människor reser mer och längre. Denna tendens och politikens ökade fokus på järnväg medför att järnvägen troligen kommer få en ökad betydelse inom stadsutveckling och eventuellt även ta mer mark i anspråk. Parallellt finns i Sverige en tendens till yteffektivisering där städer omvandlar ledig mark och övergivna tomter i en önskan att motverka urban sprawl. Problemet är att det kring järnväg skapas ytor som är svåra att använda.

With this master thesis we wanted to find out in which way the concept of public service is connected to different perspectives, ideals, visions of the future and forms of organizations. The purpose with our thesis was to do an analysis of different concepts regarding to public service. To the analysis of concepts we used Swedish newspapers and analysed the issue of public service that had been discussed in articles written during the last five years. From this material and other papers about public service we developed a model of public service ideals. We wanted to find out what the different perspectives thought about the Swedish television and their commission.

A distributed hydrological rainfall-runoff model has been developed using a GIS integrated with a dynamic programming module (PCRaster). The model has been developed within the framework of the EU-project TWINBAS at IVL Swedish Environmental Research Institute, and is intended for use in WATSHMAN ? a tool for watershed management developed at IVL. The model simulates runoff from a catchment based on daily mean values of temperature and precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model.

Arbetets syfte är att undersöka hur man kan planera och utforma en hållbar dagvattenhantering på förorenad mark utifrån området Kopparlunden i Västerås. I Kopparlunden planeras en utveckling till en blandad stadsdel präglad av hållbara lösningar där dagvattenhantering blir en betydande del. Hållbar dagvattenhantering är en viktig del i klimatanpassningen av stadsmiljön men också för att minska föroreningsbelastningen på sjöar och vattendrag. Öppna dagvattenlösningar använder naturens principer för att fördröja och rena dagvattnet så nära källan som möjligt, ofta genom infiltration. Genomtänkta och platsanpassade öppna lösningar kan skapa mervärden i stadsmiljön, till exempel biologiska, estetiska och upplevelsemässiga.

Aim The purpose of this research is to study the need and the importance of marks in secondary school. The reason is to find out the students' perception of how they are motivated. Furthermore, how students experience the assessment and grading in physical education.What attitudes do students have towards the mark in the subject physical education in 6th and 9th grade, also how does SOC affect their attitudes towards marks?What kind of motivational significance do marks in physical education have in 6th and 9th grade based on their SOC?How do the students experience the assessment in grading in 6th and 9th grade based on their SOC?Method The data was collected with a quantitative approach. The sample consisted of four classes from 6th grade and five classes from 9th grade; all from two different schools in the county of Stockholm.

This essay examines how the meaning of an absurd play may be affected by how the reader understands the text. To address this problem I have turned to Wolfgang Isers theory of reception. Primarily I have taken on that the creation of meaning comes about when the reader fills in blanks in the text. I have also used Martin Esslins work on the theater of the absurd. I have mainly studied his research on Harold Pinter.

The purpose of this thesis is to examine whether the concept of permanent establishment, as defined in Article 5 of the OECD Model Tax Convention on Income and Capital, is applicable to electronic commerce and if so whether the current definition is able to appropriately deal with the challenges of electronic commerce.In 2003, the OECD added a new section to the Commentary on the Model Tax Convention on Article 5. The new section is a clarification on the application of the permanent establishment definition in electronic commerce.The current definition of permanent establishment in the Model Tax Convention relies on the physical presence of a foreign corporation as the threshold for source taxation. While the current definition, prima facie, might be applicable on electronic commerce, the highly mobile nature of electronic commerce might affect the current revenue distribution equilibrium between states..

Det finns idag en påtaglig bostadsbrist i Stockholmsområdet och detta samtidigt som regionen förväntas få en kraftig inflyttning de kommande tjugo åren. Krav finns på kommunerna att friställa byggbar mark för ny bostadsbebyggelse. Detta arbete konkritiserar problemet genom en fallstudie av gammal industrimark som snart kommer att friställas för bostads- och verksamhetsbebyggelse. Fallstudien görs på Bergs oljehamn i Nacka kommun. Under det senaste decenniet har nyexploatering av hamnmark skett nationellt i Sverige liktväl som regionalt i Stockholmsregionen.

Rising energy prices and higher energy demands have led to an increased focus on energy efficiency, in particular in the real estate business, where high potential for energy savings exists. Within the next few years, buildings that were constructed in the sixties and seventies will be in need of renovation. One of the challenges of these renovations will be to improve energy efficiency. A real estate company that is facing this challenge is Uppsalahem AB, based in the city of Uppsala, Sweden. This study focused on analyzing energy efficiency measures when renovating old buildings.

In this essay dog as a compatible model were put against human. The major histocompatibility complex (MHC) genes were compared between dogs, human, cat and mouse. To evaluate dog as a model and study similarities and differences was the aim with this review. Dog as a model contributes to understand mechanisms behind autoimmune diseases and showed clearly histological similarities between human and dogs concerning the skin disease mucous membrane pemphigoid (MMP)/cicatricial pemphgioid (CP). Further genetic evidence motivated the choice of using dog as a comprehensive model when the MHC-complex correlated with hypothyroiditis in Doberman dog as it does in human. Physiological similarities with low levels of thyroid hormones (T3 and T4) together with high level of thyroid releasing hormone (TSH) were found in the same way as in human.

Den svenska Försvarsmakten brukar fråga sig om den är tillräckligt interoperabel för att kunna delta i internationella insatser. En minst lika berättigad fråga borde vara om den är tillräckligt interoperabel, mellan sina försvarsgrenar, för att kunna genomföra självständiga operationer utifrån teorin om gemensam krigföring. Den bristande förmågan till gemensam krigföring i försvarsmakter generellt och för Sveriges Försvarsmakt specifikt utgör uppsatsens grundläggande problem. Genom att anpassa och skapa ett analysverktyg utifrån Codners och Sjöbloms interoperabilitetsteori har Försvarsmaktens dokument analyserats för att belysa eventuella svagheter kopplat till gemensam krigföring och nationell interoperabilitet mellan mark- och flygstridskrafterna. Undersökningen visar på svagheter kopplat till den anpassade interoperabilitetsteorin och Försvarsmaktens styrande dokument.
