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.

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.

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.

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..

Syfte: Vi ämnar med uppsatsen att undersöka om det råder en skillnad i avkastning mellan portföljer indelade efter kriterier som kännetecknar värde samt tillväxtaktier. Studien genomförs specifikt på svenska marknaden och portföljernas avkastning skall utvärderas utifrån en årlig buy and hold strategi.

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.

The purpose of this study is to give us a deeper understanding about street workers importance for youths. We also wanted to investigate this from a gender perspective, both considering the street workers but also the youths. The focus for this study is on both the street workers and the youths. The study is based on a qualitative approach. We were going to study people and their behaviors.

This study aims to evaluate the value relevance of Piotroski?s (2000) nine fundamental signals. In order to do this, the signals are tested on the OMX Nordic Exchange Stockholm between the years 2003 and 2009. The hypotheses of the study are whether the signals are value relevant and if the value relevance has changed. To test this, a Chi-square test and a regression are used.

I have with this thesis sought to understand how chick lit could be useful in the classroom in the teaching of Swedish B-course in high school. Based on the model of critical literacy I am arguing that this genre would help to meet the objectives of the policy documents which, among other things, are to critically examine and analyze various types of texts.I have found that some of these texts could be used for analyzing and critically examine the ideological dimensions of texts and cultural heritage by the model of critical literacy, and also as a counterweight to the more traditional teaching of the canonical literature as a literary historical stuff that students should learn. I have also wanted to create a basis for discussions about literature in the classroom based on the chick lit genre. To do this I have, based on three themes and questions from the model of critical literacy, tried to focus on issues that might emerge from the ideological analysis and critical review. The model aims to deconstruct norms of society, and in the work of chick lit, I wanted to show how you could deconstruct norms around gender..

The purpose of this essay is to identify the costs of illness in different organizations, and compare the calculated result with the actual result in their annual reports.We collected information thru interviews with the personnel manager in the selected organizations, and used the annual reports to add necessary information.When we applied our model, we found that the selected organizations, in some cases, have a cost of illnes which is up to seven times higher than shown in their annual reports. It?s, in general, the costs that aren?t related to the salary (additional costs), which are much higher than shown.The absence of a model that calculates the costs of illnes can result in wrongful decisions. If a model would be applied in an organization, it should increase the awearness of the actual costs of illnes, which can lead to better decisions througout the whole organization.This report is written in Swedish..

In order to facilitate trade between EU members, the European Committee has created regulations that will govern supervision of organic products. Every regulatory agency shall, according to the European Committees regulations, carry out a risk classification of each organic producer they regulate. This study for The National Food Administration compares regulation of Swedish organic products with other countries, and aims to produce a simplified model based on risk that can be the beginning of the risk classification model that Sweden in the current situation don?t have. The thesis is based on three questions: 1) What criteria should we use for assigning organic food producers? 2) How do selected European countries and frontrunners rate organic producers and what can Sweden learn from them? 3) How might a national classification model of organic production look in order to ensure an equivalent level of regulation and prevent competition among private inspection bodies? A review of information gathered from the different countries gave differing results.
