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.

The aim of this paper is to examine the capacity for ethical reasoning of Swedish certi-fied auditors in the five largest accounting firms in Stockholm, and also how ethics courses affect the auditors' ability to ethically statement. To calculate the auditors ability to ethical statement, questionnaire has been used. The questionnaire is based on a psychological instrument, the so-called Defining Issues Test. At the beginning of the questionnaire some questions are asked about the ethics courses. From the questionnaire a calculation was made of an average index called p-score (Principled score).

The swedish national board of housing, Building and Planning,recommends that all stakeholders in the construction industryperform a moisture control design to make sure that the buildingachieves good moisture resistance. Since June 1, 2006 there are nospecific requirements or quantitative values for air leakage.Although the swedish national board of housing does presentrequirement that the building envelope must be sealed so that theclient?s requirements for specific energy consumption and installedelectric power for heating purposes are met. Despite this, studiesfrom SP shows that few buildings meet the client?s requirements inspecific energy, which increases the risk of occurrence ofcondensation-related moisture damage.This study aims to evaluate curtain walls connections from airsecurity and moisture safety.

The ability for companies to anticipate the future and stay in the forefront of the competition is essential for successful business. The tool of Environmental Scanning is basics in the process of developing prescriptive strategies as well as vital in evolving emergent strategies. The complexity lies in gathering relevant information and transforming the information into adequate data, which can be utilised by management to optimise strategies. The purpose of this study is to scrutinise how successfully operating Swedish manufacturing companies, listed on the Stockholm Stock Exchange?s ?Large Cap?-list, organise their Environmental Scanning actions and how this affects the development of strategies. Prior research on the subject has been used as foundation to presenting relevant theories.

The purpose of this thesis is to examine whether institutional ownership has an influence on CEO compensation in companies where the institutions have invested. In order to fulfil the purpose of the thesis a quantitative study was carried out within the Swedish corporate context where we have studied Swedish institutional investors and companies quoted on the Stockholm Stock Exchange. Our period of study was the financial year of 2007.The empirical questions at issue is; Was there a connection between Swedish institutional ownership and the size of the CEO compensation, and, does Swedish institutional ownership lead to a certain type of CEO compensation in terms of structure?Our results did not suggest that an increased institutional ownership neither leads to a certain type of salary level nor a certain kind of salary structure. These results contradict earlier American research, which has been done within this area and has previously shown a secured connection.The reasons for our results may be many and it is difficult to state any concrete conclusions to why we received differing results.

With increasing traffic congestion problems in bigger cities, it is becoming more and more important to provide the traveller with correct information about all transport alternatives. When doing that, the traveller gets the opportunity to make the best decision based on the current traffic situation. Instead of traditional travel planners, where public and private transport modes are presented separately, the co-modal travel planner offers a combination. In order to make the comparison correct and fair, the travel times have to be estimated realistically and on equal basis. This master thesis focuses on how to estimate travel times in the city of Stockholm for journeys by cars, public transport, bicycles and also for walking.An investigation of the available data on maps and travel times shows where the currently used methods are lacking.

The energy in laundry rooms, in form heated air, can be utilized with a heat exchanger. A concept and an early prototype of the heat exchanger have already been developed to show that the theory works. This report describes the continued development and construction of the product.A field study was made in order to investigate the environmental usage and establish the product design. The most common washing machine was used as a calculation model, and calculations were also made to estimate the amount of energy in the air. A previous analysis of the existing prototype is also presented in this report, to show the products potential capacity.

With gas prices persistently rising, electric and hybrid vehicles are getting more and more common and in recent years several new electric cars have evolved on the market. Although the energy consumption and low emissions are a huge benefit of the electric cars, they inevitably suffer from high prices, short range and time consuming recharging periods. To be able to withstand the competition it is important that electric vehicles not only can withstand general were and tare, but also the harsh conditions that ordinary cars is exposed to in daily usage. The purpose of this project is to develop a test methodology which replicate situations that could appear in daily usage of electric or hybrid cars and to understand the problems related to usage of electric cars in winter conditions. This paper also discusses the major differences between hybrid cars and electric cars.

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

Länsförsäkringar in Värmland, Sweden, had during the year 2003 a total level of 6.1 percent of people on the sick-list, which was higher than average in the business (4,5%) and for salaried employees in the private sector (3,3%). The average age of those put on sick-list was 47 years, whish is four years higher than the average for the whole LF-group. The cost for the total amount of people being on sick-list at LF-company (6,1%) was estimated to 1 500 kkr, according to a calculation model coming from Försäkringskassan. For every percent the sick level could be reduced, the company would save 239 kkr. To map out the state of health of each and every collaborator in LF, the company offered all employees to make a health profile at the company's health service, Clarahälsan AB.

This report is an inventory of the street lighting in half of the residential estates owned by Karlstad Bostads AB, a public housing company. The inventory was made to reduce the environmental impact of the street lighting. From the inventory an estimation of the total installed power and the energy consumption was made. The total estimated power of the street lighting was 125 kW and the energy consumption was 500 000 kWh/year with an estimated running time of 4 000 h/year. The dominating source of light was 125 W discharge mercury lamps.

Syftet med denna uppsats är att granska effekterna av regional integration på FDI hos de länder som blev medlemmar i EU 2004 samt 2007. Utifrån teori gällande sambandet mellan regional integration och FDI, analyseras empirisk data över stock och flöden av FDI till de nya medlemsländerna i syfte att utreda förekomsten av investeringsalstring och/eller investeringsomfördelning inom denna integration av typen öst-väst där det råder stora skillnader i inkomstnivå mellan medlemsländerna. Analysen visar att FDI till de nya medlemsländerna, både från andra medlemsländer och tredje land, har ökat till följd av ländernas medlemskap i EU. Mätt i absolutvärde kan det konstateras att FDI från andra medlemsländer är avsevärt mycket större än FDI från tredje land. Vidare har de nya medlemsländerna upplevt investeringsalstring och investeringsomfördelning från andra medlemsländer samt investeringsomfördelning där FDI från EU15 flyttar från tredje land till de nya medlemsländerna.

The aim of this Master?s thesis is to examine how librarians in two Swedish public libraries view the subject of face-front marketing and literary hierarchy. The questions posed in this thesis are: How do two public libraries in Sweden market fictional literature? Which literature does get marketed? How do the librarians view fictional literature? How do the librarians view marketing? and Does Herbert Gans? literary scale work to examine the marketing of fictional literature in two Swedish public libraries? The theoretical starting-points are Niels Ole Pors? thoughts on stock development, Philip Kotler?s thoughts on the responsible non-profit organisation and Herbert Gans? thoughts on taste-publics and taste-cultures. The empirical material was gathered through qualitative interviews with library staff in two public libraries in the south of Sweden, and by reading a sample of the fictional literature exposed in these libraries.

Syftet med denna litteraturstudie var att ta reda på vilka olika typer av tandskydd som finns, hur vanligt användandet av tandskydd är inom idrott och vad det är som gör att vissa avstår från att använda tandskydd. För att få svar på detta gjordes en sammanställning av tidigare vetenskapliga artiklar. Det finns tre olika typer av tandskydd. Typ I, stock-type, finns i olika storlekar och kan köpas i handeln. Typ II, boil-and-bite, finns också att köpa ute i handeln och idrottaren formar till tandskyddet själv i munnen. Typ III är ett specialgjort tandskydd som tillverkas hos tandläkaren.
