Reglerstrategi för fria ventiler : ? Utveckling av en fyrtakts förbränningsmodell för att prediktera optimala ventilinställningar
As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.
Utveckling av en Multi-Zonsmodell för NOx Bildning i Diesel Motorer
This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.
Riskkapitalets inverkan på operationella investeringar - En jämförande studie av svenska portföljföretag
This thesis seeks to explain the effect of private equity ownership on the amount of invest- ments made in a company. We use three capital expenditure based key ratios to determine if there is a tendency for private equity owned firms to invest more or less than comparable companies. Our dataset involve 27 Swedish buyout companies that were sold by a private equity fund between 2001 and 2009. Each buyout is assigned a peer group of two firms in similar size and in the same industry. Firstly, we compare the key ratios to determine potential differences in the level of investment.
Delad kunskap - dubbelt lärande. Kan användningen av e-post påverka organisatoriskt lärande?
Eftersom e-post är ett utbrett kommunikationsverktyg som inte sammankopplats med orga-nisatoriskt lärande i någon större utsträckning, anser vi det vara ett praktiskt och teoretiskt intressant ämnesområde. Syftet med uppsatsen är att visa om användningen av e-post kan kopplas till organisatoriskt lärande. Förutsatt att denna koppling kan göras undersöker vi hu-ruvida e-post bidrar till eller hämmar det organisatoriska lärandet och i så fall på vilket sätt detta görs. Undersökningen utgår från en litteraturgenomgång som beskriver kunskapsteori, lärande-teori och knowledge management. Vidare definieras e-postmediets egenskaper som kommu-nikationsverktyg.
The impact from pre-M&A resource allocation on the post-M&A performance
Background: When firms grow through acquisitions it is commonly debated whether the two entities ought to be better off as standalone companies rather than as a merged company. This thesis aims at discussing this issue of M&As advantages and disadvantages in terms of source of synergies from the perspective of resource allocation. Purpose: The purpose of this thesis is to describe and analyze to what extent pre-M&A differences (against similarities) in resource allocation and corporate culture between the acquiring and target firm have an impact on the post-M&A performance. Theoretical framework: Efficient market hypothesis, resource based view, strategic fit. Methodology: A longitudinal study is conducted on the EU market during 1992 to 2002 based on balance sheet and income statement data.

Fakturahantering företag till företag : En studie kring två olika tillvägagångssätt (Post&PDF)
Att fakturera är något som alla företag måste göra för att tjäna pengar. Fakturering kan ske på flera olika sätt och det finns olika åsikter vad som är att föredra bland företag när det handlar om hantering av fakturor. Teorin menar på att använda sig av elektroniska faktureringssätt är mer effektivt än fakturering via traditionell post. Syftet med denna forskning var att ta reda på varför företag i Sverige år 2015 väljer att skicka, mottaga och hantera fakturor med post när det finns alternativa metoder som PDF via mail och vad det är som gör att företag inte byter från det ena förhållningssättet till det andra..
Uigurerna - de Andra. En postkolonial studie av en muslimsk minoritet i Kina
In this thesis I have used post-colonial theory to analyze the Uyghurs, a Muslim minority group located in Xinjiang province in the Northwest of China, and their identity shaping process in relation to the dominating Han Chinese. I have analyzed the possibilities to use the power perspectives in post-colonial theory, especially Edward Said's Orientalism and the creation of the Other in a new context, where the main focus is on the Uyghurs through the eyes of Han Chinese. I have argued that Han Chinese, with colonial tendencies, have created two generalizing pictures of the Uyghurs; one romantic picture to use as an exotic tourist attraction and one threatening picture that portray Uyghurs as Islamic terrorists to win support in international politics. The thesis is a qualitative single case study with the aim of gaining a deeper understanding for the Uyghurs as well as examine possibilities of widening the analyze areas for post-colonialism. My conclusion is that the power perspectives in post-colonial theory are usable implements also for non-western contexts and in this case function as a way to understand the identity shaping process for the Uyghurs and their relation to Han Chinese..
Teknisk och ekonomisk analys av en bränslekonvertering vid SIA TallOils pelletsfabrik :
At SIA TallOil's pellets factory in Latvia wood shavings and saw dust are dried with flue gases from a gas burner. TallOil wants to replace the gas with a biofuel that is available at the pellet plant. The reason for this is the unstable gas market in Europe in combination with the fact that TallOil wants to improve its profile as supplier of renewable bio fuels. In this project the technical and economical possibilities for a fuel conversion to ether bark powder, wood shavings or wood powder have been investigated. These fuels should be burned in one of the following applications: TPS BioSwirl, VTS Multifuel burner or Saxlunds bio fuel combustion plant
Due to the fact that the fuel alternatives available are relatively common except for bark powder, the work has mainly been focused on bark powder.
En holistisk investeringsbank - En fallstudie av fördelarna med att vara involverad i hela M&A-processen
Studies have shown that mergers and acquisitions often fail and that a reason to this might be that investment banks do not take any responsibility for the post merger integration. Despite this there have been no studies of the potential benefits of an investment bank taking a holistic approach to the M&A-process and including post merger integration in its service. This study identifies a couple of investment banks that does this and calls them holistic investment banks. In M&A-theory a successful process is often described according to so called success factors that need to be fulfilled in order to achieve a successful result of the merger or acquisition. The business model and work approach of one holistic investment bank is analyzed in this case study on the base of seven success factors from established theories.

Evaluation of a behaviour protocol for use in recording the behaviour of horses following administration of methadone
There is a need for correct and adequate pain assessment in horses. Methadone is used in pain management in horses but the full pharmacokinetic picture of methadone is not yet known. The aim of this pilot study was to develop a behaviour protocol and suggest a reliable recording method for use in a larger research project with an aim to potentially correlate behaviours to concentration of methadone in blood. In this study two coldblooded trotters were given methadone intravenously with doses of 0.1 mg/kg for horse 1 and 0.2 mg/kg for horse 2. The horses were videotaped pre and post methadone administration.

Ett oväntat samarbete - Effekter av tematisk inkongruenta sponsorsamarbeten mellan bloggare och välkända varumärken
As a great deal of people spend more time with their cell phones and computers than with magazines and TV, markets have begun to explore marketing possibilities in digital media. A common form of marketing in digital media is sponsorship of the cyber stars of the Internet - the bloggers. Sponsorship of bloggers has proven to be a highly efficient method for brands to gain attention and positive attitudes, as bloggers are regarded as fashion icons as well as reliable friends. Another up-to-date marketing strategy that has proved successful in gaining consumer attention is the use of incongruent elements in ads. Incongruence challenges consumer expectations and thereby demands attention.
Emotikoner som affektivt hjälpmedel i samband med elektronisk post
Jag vill med denna uppsats undersöka vilket inflytande emotikoner har på läsare av elektronisk post meddelande. Totalt fanns det 39 deltagare som fick bedöma tonen i de fyra e-postmeddelanden varav två med emotikoner och två utan emotikoner. Hypotesen är att emotikoner kommer att generera en större afektiv respons hos den som läser e-postmeddelanden än vad meddelanden utan emotikoner gör. E-postmeddelanden innehållande emotikoner genererade inte större affektiv respons än de utan emotikoner..
