A piezoelectric injector was modeled, in this Master Thesis Project which was carried out at Scania CV AB in Södertälje, in GT-Fuel. GT-Fuel is simulation program from Gamma Technology.The simulation model for the piezo injector was divided into a hydro-mechanical system and an electrical system (Piezoelectric element). First the hydro-mechanic model was duplicated from Advance Continuous Simulation Language model (ACSL). The simulation results were then compared to the ACSL, to verify that the hydro-mechanical system was modeled correctly. The simulation results for the electrical model were also compared with a Simulink model.

Heat is distributed to the district heating customers through pipes with water as a heat carrier. The district heating system is complex. To decide what is leakages from the district heating net versus what is the water consumption of the plant, is difficult. Therefore, the purpose of this master thesis is to establish a model where the district heating net?s leakages but also the water consumption of the plant can be followed daily. The project is performed at Vattenfall´s district heating power plant in Uppsala. Information is gathered through discussions, drawings of the plant and guided tours of the plant.

Inledning: Strukturerade professionella riskbedömningar för våld, vilka inom polisen benämns som riskanalyser, är numera ett krav och en viktig del i det brottsförebyggande arbetet inom polisen i Sverige. Polisen använder i huvudsak tre checklistor för att bedöma risk: SARA: SV, SAM samt PATRIARK, vilka generellt upplevs som praktiskt användbara. Dock är det få polismyndigheter som arbetar aktivt och ändamålsenligt med dessa. Inom Polismyndigheten i Gävleborgs län arbetar personsäkerhetsenheten för att främja tillämpningen av riskanalyserna och vi önskar bidra till att utveckla detta arbete. Syfte: Utifrån polisers upplevelser undersöka förutsättningar för och begränsningar av de strukturerade riskanalysernas tillämpning inom Polismyndigheten i Gävleborgs län.

The purpose of this essay is to try to understand the relationship between the structures of modern working life and the development of burnout. By using the method of qualitative interviews we wanted to see if the Effort-Reward Imbalance Model could be applied to the data we had collected. Two questions have been highlighted in our research:        ? Is it possible to establish a relationship between the structures of modern working life and the development of burnout among the subjects interviewed?  ? Is it possible to explain the development of burnout among our interviewed subjects through the Effort-Reward Imbalance Model?    Our theoretical frames are the general theories of the modern society and the modern working life as developed by Anthony Giddens, Ulrich Beck and Zygmunt Bauman. We have also used Johannes Siegrist?s medical-sociological Effort-Reward Imbalance Model (ERI-Model).

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.

Syskonbädd, or ?Sibling?s bed? in English, is a short story or drama, written by Swedish author Stina Aronson and originally published in 1931 under the pen name Sara Sand. While the story did not attract wide attention for many years, it has recently been republished and performed on stage, as well as aired on the radio. The plot is centered on Harriet, a woman who starts to see the world with different eyes, in a less strict and organized way. Her new view is welcomed neither by her husband nor society, and the book starts with Harriet?s escape from a ?rest home?, where she has been placed by her husband in order for her to return to her old self.

Denna studie har som syfte att betrakta hur bisatsanvändning hos vuxna avancerade inlärare av svenska som andraspråk ser ut jämfört med inlärare med svenska som modersmål; detta med avseende på både frekvens och variation.För att besvara mina två frågeställningar angående först frekvens och sedan variation har jag valt att granska uppsatser skrivna av L2- och L1-komvuxstuderande som har gått de högskolebehörighetsgivande gymnasiekurserna Svenska som andraspråk B respektive Svenska B på Komvux. Uppsatserna är skrivna som en del i det nationella prov som inlärarna har deltagit i vid slutet av kursen.För att bevara reliabiliteten för denna undersökning har jag utgått ifrån en definition och indelning av bisatser som presenteras i Svenska akademiens grammatik, kallad SAG, och Svenska akademiens språklära, kallad SAS. Genom att söka de bisatser som inlärarna använder och sammanställa dem i jämförelsetabeller har jag lyckats med att kontrollera och jämföra de olika bisatsgrupper och bisatsinledare som L2- respektive L1-inlärare använder.Undersökningen visar att det finns skillnader i bisatsanvändningen mellan dessa två inlärargrupper men att skillnaderna inte är avsevärt stora. Jämfört med L1-texterna har bisatser i L2-texterna högre frekvens vilket kan bero på att L2-uppsatserna i genomsnitt är längre, 800 ord/text gentemot 700 ord/text. Däremot har bisatserna i L2-texterna mindre variation.

Examensarbetet har innefattat att utforma ett inredningsförslag till restaurangen Down Town i Eskilstuna. Förslaget har anpassats till den primära målgruppen studenter i åldersgruppen 18 ? 35, på Mälardalens högskola i Eskilstuna. Vår uppdragsgivare har en vision om att restaurangen i framtiden ska bli en naturlig mötesplats, där studenter till förmånliga priser kan äta lunch och umgås. Utifrån en enkätundersökning, intervju med uppdragsgivaren, resultatet av rums analysen, inspirationsresan och litteraturstudier har vi arbetat fram ett helhetskoncept anpassat till målgruppen..

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..

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.
