This thesis work has been performed at the department of diagnosis and dependability at Volvo Car Company, Torslanda. The background of this project is based on interest in ascertaining how different factors possibly can affect a diagnosis method, which has been developed to find leaks in the fuel tank and evaporation system. According to the OBD II requirements leaks with an orifice diameter larger or equal to 0,5 mm, must be detected. The idea of the diagnosis method is to create an over pressure in the system with an air-pump. The current through the pump is measured and correlates to the power consumed by the pump.

Studien avser att undersöka om det finns någon skillnad mellan män och kvinnors arbetstillfredsställelse definierat som aspekter av arbetssituationen enligt Hackman och Oldhams (1976, 1980 i Arnold et al., 1998) Job Characteristics Model, och om det finns några skillnader i ålder vad gäller arbetstillfredsställelse utifrån JCM. Det var en explorativ undersökning eftersom mycket av tidigare forskning har fått varierande resultat, och vi ville se vad vi skulle få för resultat. Metoden som har använts är kvantitativ och syftet har undersökts med hjälp av en enkät. Som teoretisk bakgrund användes Hackman & Oldhams ?Job Characteristics Model? (JCM) (1976, 1980) och den användes även vid utformningen av enkäten.

The purpose of this thesis is to examine and analyze the characteristics of the management control system private equity firms use to manage their portfolio companies. The thesis takes a share holder value perspective, and it is assumed that the goal of the management control system is to increase the shareholder value in the portfolio company. In a qualitative study two private equity firms and two portfolio companies, one for each private equity firm, were studied in detail. In total, nine in debt interviews were completed. The results from this study suggest that the characteristics of the control system are dependent on the surrounding context; the focus on shareholder value and the specific characteristics of the private equity industry shape the characteristics of the management control system.

Flooding events are no longer rare, floods occur all over the world. Accordingly, it is vital for the society and different authorities to work with flood mapping. To meet the goal of Uppsala kommun to map the risks of floods in Uppsala län, a map of the different areas around Funboån which are inside the area of risk for flooding have been developed.In the work, cross sections and the water flow have been measured. Moreover, an echo-sounding have been carried out in Funboån to map the bottom topography. From the bottom map and laser scanned data covering the study area, a terrain model was created.

The purpose of this study was to examine how the genrebased instruction applied in multicultural classrooms. My observations were carried out in three different classrooms, whit the educators constantly working on language development off the students. Two observations were carried out in Swedish, with a teacher of Swedish as a second language and the Swedish-teacher working with students together. In these two lessons in Swedish, I took away from Pauline Gibbons model, while the third lesson in civics I assumed from Eija Kuyumcu genre model. Both models are based on the Australian research around the genrebased teaching.

Denna studie syftar till att undersöka huruvida arbetsmotivationen skiljer sig mellan generation Y och tidigare generationer i den svenska IT-branschen. Studien vilar på en teoretisk grund bestående av tre välkända teorier inom arbetsmotivation; Herzbergs tvåfaktorteori, Self-Determination Theory samt Job Characteristics Model. För att kunna besvara studiens forskningsfråga ?Hur kan belöningssystem utformas för att ta hänsyn till fler anställda från generation Y i den svenska IT-branschen?? genomfördes en semistrukturerad intervju med en HR-chef samt en enkätundersökning bland anställda på IT-företaget Evry. Resultatet av studien visar att det finns vissa skillnader i arbetsmotivationen mellan generation Y och tidigare generationer vilket kan motivera till förändringar i hur man arbetar med belöningar när en allt större del av arbetskraften utgörs av generation Y. En viktig skillnad som framkom är att medarbetare från generation Y uppskattar feedback mer än äldre medarbetare, oavsett varifrån i organisationen feedbacken kommer ifrån. Studien fann även att monetära belöningar kan ha en stark negativ inverkan på arbetsmotivationen, men att de under vissa omständigheter kan vara positiva och ibland även nödvändiga.

The cost of capital for traded companies is basically assessed on information from thefinancial market. Small and non-traded companies are lack of this necessary financialmarket information in order to determine an appropriate equity risk premium and tocompute the cost of capital.In the absence of financial information necessary for an external investor, it is difficult toevaluate a non-traded company with the Capital Asset Pricing model (CAPM), which isbased on the financial market information. It measures only the systematic risk, which isthe contribution of one share to the market risk of a portfolio. It is therefore important tofind models that reflect the small and non-traded companies? real business value and theirunique characteristics.

The aim of this thesis is to examine the characteristics of film cataloguing, and to compare general as in library use and specific as in archival use cataloguing rules. Most rules, both in archives and libraries, use the book as a point of reference. This is somewhat unfortunate on account of the great difference between books and films. The method used is studies of literature and qualitative interviews with three persons whose professional duties include cataloguing of films. The sets of rules which are studied are Katalogiseringsregler för svenska bibliotek KRS and The FIAF Cataloguing Rules for Film Archives.

The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

AbstractTitle: The Swedish real estate companies choices of valuation within investment properties and its further effects on the qualitative characteristics of accounting.-A study of the Swedish real estate companies listed and non - listed on the stock market, after the application of the international rule board.Background and Problem: From January 2005, all companies, listed on a stock market within the European Union, are required to prepare their consolidated accounts using common set of International Accounting Standards, IAS/IFRS. In Sweden, this opportunity has also been given to non-listed companies, to voluntary implement these rules in their consolidated accounts. One difference between Swedish accounting rules and contemporary International rules, deals with the accounting treatment of investment properties, which foremost affects the real estate market?s accounts. In contrast to the Swedish Financial Accounting Standards Council?s recommendation RR 24, the new standard, IAS 40, permits a choice between different accounting alternatives.

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

In this master thesis a robot arm belonging to an automatic milking machine from DeLaval is investigated. The robot arm is controlled by a pneumatic cylinder and a valve. The goal of the master thesis is to investigate instability problems and to find out if it is possible to solve them by using gain scheduling. Gain scheduling is a type of controller where the parameters of the controller are changed during operation, for example depending on the working point. First a nonlinear mathematical model of the system was made.

A growing number of cities and municipalities in Sweden begin to work with city models in 3D. For the most part the models are used for visualizations of ongoing planning processes, but also for the analysis of noise, shadow studies and environmental disaster simulations.Gothenburg continues to develop the use of 3D maps in municipal operations and is demanding a way to create building elements (walls), which generates in 3D buildings, from roof constructions that are mapped from the primary map. A method has been investigated in the present study. The results are then presented as a 3D model of buildings, along with a terrain map that will facilitate the localization of the area. The created 3D buildings are then compared with roof-data from the primary map to see how well they harmonize with each other.

Context: During the 21st century several alarming reports have been published that deals with the depletion and pollutant of the earth by human interference. The earth is an ending resource and so are the mountains and bedrocks which are continuously mined in order to harvest its minerals. The idea behind Urban Mining is to (re)invent processes enabling further purpose for materials both from old deposits and new products providing secondary raw materials and energy. This thesis aims to investigate the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between product-/service systems, economic growth and environmental stewardship in the context of Urban Mining as an approach. With the innovation of processes, technology, business- planning and creation in focus.Objective: How to future proof a business model for Urban Mining by the usage of business model design.Method: This thesis will be conducted using a case study approach, meaning that it will incorporate qualitative, exploratory and descriptive characteristics - aiming towards enabling both applied and fundamental research.Results: The result evaluates the business model element differences between traditional C&D industry and Urban Mining industry.
