Beskrivning av systemfunktioner i kärnkraftverk med hjälp av objektorienterat modelleringsverktyg
In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants.
Attityder till certifieringssystemen FSC och PEFC i skogsbranschen
Different groups in the forestry sector were likely to have different views regarding the responsibility for an environmentally sustainable forestry and the benefits of certification and this study aimed to examine the attitudes that existed in the forestry sector to the certification schemes FSC and PEFC. In the study a survey and a questionnaire were sent out to different groups. The investigation was made with respect to three groups: forest owners, forest contractors and employees working with the certification schemes on a daily basis at the forest company Södra. The groups agreed that the owner of the forest had the main responsibility for an environmentally sustainable forestry. The study revealed that all three groups highly valued the environmental aspect of certification.

Theequipment is made to be used for research on eyemovements. In the second part, a computermodel of a part of the balance organ in the inner-ear is developed. The work has been done atthe Bernadotte laboratory at S:t Erik Eye Hospital.The equipment the control system is made for is a so-called rotationchair.
Metodik för optisk mätning av sprickbildning i dragen betong på mesonivå
This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.
Lärares arbetsmotivation och arbetstillfredsställelse - Skiljer sig upplevelsen beroende på organisationsform och kön?
Studiens syfte var att undersöka om det förelåg några skillnader i upplevelsen av arbetsmotivation och arbetstillfredsställelse bland lärare avseende organisationsform och kön samt om det fanns en interaktion mellan organisationsform och kön avseende arbetsmotivation och arbetstillfredsställelse. Totalt deltog 84 respondenter i undersökningen. Mätinstrumenten som användes var Minnesota Satisfaction Questionnaire och Basic Need Satisfaction at work scale. Resultatet visade att det inte förelåg några signifikanta skillnader i arbetsmotivation beroende på organisationsform och kön. Vidare visade resultatet att det fanns signifikanta skillnader i yttre, inre och generell arbetstillfredsställelse beroende på organisationsform, där privatanställda var mer tillfredsställda i jämförelse med offentligt anställda.
Kostnadsallokering genom ABC-kalkylering – en empirisk studie av OMX
As IT service departments in organisations are becoming more complex and customised, the indirect costs are increasing in relation to the total costs. The difficulty of fully estimating and identifying the spread of the cost in the IT service department is increasing. As a result, firms tend to budget the business unit as a total cost rather than as a spread of defined costs. In order to deal with this challenge an ABC calculation will be applied. The Time Driven ABC model will be conducted in OMX´s Servicedesk unit within the IT services.
Genrebaserad undervisning : att stötta flerspråkiga elever i deras språkutveckling
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.

Simulering av vindkraftverk och närliggande elnät vid Risholmen i Göteborg i SimPowerSystems
With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.
Kvalitetssäkring och processtyrningav ytstruktur på lackerat objekt
To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..
Den öländska älgstammens förvaltning : en granskning av förvaltningsplanerna och jaktens upplägg
To Swedes in general and, to hunters in particular, there is a great interest for moose (Alces alces), witch is Sweden?s largest deer species. In the province of Öland (Sweden?s second largest island) the local people show a great interest for the moose existence, both for consumptive (hunting) and non-consumptive use (tourism). This became apparent in 2002 when the moose hunters on Öland voluntary agreed to temporarily postpone the moose hunt on the island.
Justifying high price with Total Cost of Ownership awerness - possible or not on the Asian market?
Purpose: The aim with the report is to investigate if the South East Asian customer on the food processing market base their investments on Total Cost of Ownership and if so, which are the cost drivers considered most vital. Moreover, do these cost-drivers diverge from the perception FP Ltd has, and if so, can a Total Cost of Ownership-model help to achieve a mutual understanding? Methodology: First a descriptive approach will be taken, identifying FP Ltd?s employers? perception on how to meet the customer. This will later be compared to our empirical findings of the actual customer behaviour in Thailand and Vietnam. Thorough analyse of the gap between the two parts will give us the outcome whether or not FP Ltd will have any use of presenting a quantitative model justifying their higher price.
Att placera företagsinkubation i en Community of Practice - En studie om lärandemiljön i företagsinkubatorer
The role of small businesses is fundamentally important for the economic development in countries. Within this context, business incubation is used as an entrepreneurship development instrument to promote and support new firms in the early stage of their existence. However, research in the field tends to disregard the perspectives of incubatee entrepreneurs. The performed investigation is based on interviews with entrepreneurs from two different business incubators at Swedish universities. This study uses a Situated Learning Theory (SLT) as a theoretical framework, to examine the entrepreneur's experience of the learning environment in a business incubator.

Värdedrivare i buyout-investeringar av noterade private equity-bolag - En empirisk studie av 15 svenska buyout-investeringar 1998-2012
Sweden is a world leader in listed private equity and ranked fifth in the world in market capitalization. The sector is attracting increasing interest from the investment community. However, the private equity industry in Sweden has historically poor reputation and is criticized for creating value through high leverage, multiple riding and severe cuts. This study analyzes value creation drivers in buyouts from the perspective of the private equity firm using a dataset of 15 realized buyouts by private equity firms listed on NASDAQ OMX Nordic Stockholm. The methodology used separates the value contribution of leverage on the private equity firm's return from internal operational improvements and external variations in transaction multiples.
