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.

Det här arbetet är en utvärdering om huruvida det finns problem som kan få en prestandavinst då man använder en Field-Programmable Gate Array (FPGA) som hjälpprocessor till en mikroprocessor i jämförelse men att enbart använda en mikro-processor. För att avgöra detta implementerades algoritmen gaussfiltrering dels på en mikroprocessor med språket C och dels för en FPGA med hårdvarubeskrivningsspråket Very-High-Speed Integrated Circuits Hardware Description Language (VHDL). Simuleringar gjordes för dessa två implementationer och resultatet visade att det var möjligt att få en prestandaökning på 25 gånger för denna speciella algoritm..

This paper was part of the ongoing cooperation between the Swedish Civil Aviation Authority and the Department of Psychology at Lund University. The purpose of this study was to develop a self-report measure regarding human factors, for the air traffic controllers to fill out before they start their working shift. This in order to aid the team leaders in their judgment regarding the air traffic controller's ability to perform at the right safety level. The self-report measure would also serve as an aid for the air traffic controllers who have a responsibility regarding their own performance. If successful this self-report measure would make it easier for the air traffic controllers to be alert regarding certain factors that can have a large impact on their performance.

The main purpose of our paper is to reconstruct the intervention logic of the Swedish government's proposal to introduce a tax deduction for homework help. Furthermore, we also intend to outline the perceived impacts of this tax deduction in the municipality of Linköping. Our material consists of the government bill regarding the tax deduction, the parliamentary debate which preceded it as well as interviews with key people in the municipality of Linköping. In our study and in the light of Matthew Clarke?s theory of neo-liberalism within education policy, we also ask ourselves if the intervention logic behind the tax deduction and its perceived effects can be seen as a manifestation of neo-liberalism.

A new code for corporate governance was introduced for major companies in Sweden in July 2005. This act is to some degree a follower to the Sarbanes-Oxley Act that was introduced in the U.S.A. after the Enron scandal. The purpose of this thesis is to evaluate the effect on the controller in response to the introduction of this new act. Three controllers in major Swedish companies was interviewed and asked if and how they had been affected by this new act.

AbstractSAAB has for a long time used user controlled pilot models in ARES. ARES is a simulation tool used in the desktop environment for simulations and calculations of the JAS 39 Gripen fighter and other aircraft. ARES stands for ?Aircraft Rigid body Engineering Simulation?. To work with these pilot models has been both time-consuming and inefficient.

SEM AB utvecklar och tillverkar tändstyrenheter för förbränningsmotorer, bland annat naturgas- och biogasmotorer. Tändstyrenheterna styr själva tändförloppet när de får en triggsignal från motorstyrsystemet (ECU). På grund av att enheterna används tillsammans med flera olika motorstyrsystem måste de anpassas for olika signaltyper och cylinderantal. Anpassningar av både mjukvaran och hårdvaran måste göras och detta kräver tid och resurser för utvecklarna på SEM.Syftet med detta arbete är att utveckla ett ingångsinterface till tändstyrenheterna som möjliggör att de kan anpassas på ett enklare sätt. För att minimera antalet komponenter i tändstyrenheterna ska även funktioner som realiseras med diskreta komponenter, om möjligt, integreras i ingångsinterfacet.En lämplig programmerbar krets för detta ändamål har valts.

This thesis researches the value creation process in Internet based subscription services in accordance with service dominant logic. The aim of the paper is to identify the characteristics of these services and to envisage the future of Internet based subscription services. The authors have utilized a qualitative method in their research which consists of personal interviews as well as a focus group. The main theoretical subjects that are discussed are value creation, customer participation and service dominant logic. The paper analyses the empirical findings by matching them with the theoretical framework.

Abstract: The purpose of this study is to examine how the Swedish policy of neutrality has changed between the years 1990-2008. The research method used for this essay has been comparative case study, which strives to answer four research questions. Two of these questions are: Which specific occurrences have been fundamental in changing the Swedish policy of neutrality? How have the Swedish policy of neutrality and the policy of non-alignment changed between the years 1990-2008? The theoretical frame work of this study consists of Europeanization as a comprehensive theoretical perspective. In order to explain the Swedish act regarding the policy of neutrality, Logic of Consequences and Logic of appropriateness are used.

Some researchers claim that we are witnessing the advancement of becoming a network society, and in spite of the different problems associated with the network form of organization, many cities still choose to engage in different types of networks. On account of that the aim of the study is to examine which expectations Swedish member cities of the network Eurotowns might have, and if their actions in the initial period of engagement in Eurotowns mainly could be explained by ?Logic of Consequentiality? or ?Logic of Appropriateness?.A qualitative research method was used and a major part of the empirical material consists of the information given by the interviewees.Regarding the expectations Swedish member cities have on Eurotowns, the result showed that five main areas could be identified mutual resource exchange, activities, breadth, security and meeting place. The results also showed that the actions of Swedish member cities may vary between ?Logic of Consequentiality?, ?Logic of Appropriateness? or a combination of the both logics.Furthermore the study also provides empirical evidence supporting the previously theoretical criticism expressed regarding the central assumption that the strategic actions of an actor can be regarded as a direct consequence of the mutual resource dependency..

I dagens platsannonser frågas det ofta efter controllers, men få vet egentligen vad yrket innebär eftersom rollen skiljer sig från arbetsplats till arbetsplats. Vi ville studera detta diffusa begrepp för att få en större klarhet i vad titeln innebär och vilka arbetsuppgifter som är karakteristiska controlleruppgifter. Syftet med uppsatsen är att beskriva vilka arbetsuppgifter som har störst betydelse i olika organisationer. Utifrån tidigare forskning har vi skapat en modell som visar en uppdelning mellan olika organisationsformer och vilken/vilka av controllerns funktioner som blir extra betonad i de olika.Vi har gjort en undersökning omfattande 30 telefonintervjuer med controllers eller personer med motsvarande arbetsuppgifter. Intervjuerna har utgått från en intervjuguide med både öppna och slutna frågor.

This study aims to map out the degree of mediatization present in the communication between Swedishpublic service journalists and politicians in the 2014 election campaign. In doing so we chose to look at thepresence of media logic in their communication with each other. Specifically, we have used the pre-electioninterviews with the party leaders from Sweden?s two biggest parties. Furthermore, we have chosen to focuson Sveriges Radio, the Swedish public service radio company.Sveriges Radio concists of four different radio channels, of which we have chosen to focus on the channelsP1 and P3, the first having a somewhat more ?serious? profile, focused on producing quality news and otherjournalistic products, while P3 is leaning towards a younger audience and describes its own work as ?soft,humorous and important radio?, mixed with music and other forms of entertainment.
