The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.

This essay deals with the same task that utilitarians have tried to solve for a long time, what is happiness? In the eighteenth-century utilitarians suggested that happiness should be the base for social political decisions. But the lack of definition disposed so that GDP became the measurement of happiness, which proved to be wrong when the unhappiness continued to increase. More than two hundred years later scientists came up with a new definition of happiness and new ways to measure it. And during the last decade economists have taken the discussion to a higher level.So once again we?re dealing with the same old issue, if happiness ought to be the base of social political decisions.

This thesis studied which factors affect political participation among people with physical disabilities in Sweden.? The aim of the study was to test how Civic Voluntarism Model should explain the low political participation among people with physical disabilities in Sweden, through deep interviews.? Following research questions has been studied in the thesis:? How can the Civic Voluntarism Model, based on the time, communicative skills and economic resources, explain the low political participation of people with physical disabilities in Sweden??Which other factors, linked to accessibility, discrimination and legislation, are needed to further explain and understand the barriers to political engagement and participation for people with physical disabilities?? Results about treatment, clearer legislation, economic possibilities and inclusion was central. It became important to considered that where is differences in which capabilities where are to political participation. The CVM could partly explain the low political participation among people with physical disabilities. It needs to be complete with external factors; accessibility, discrimination and legalization, to make more inclusive explanations.? .

The purpose of this Masters thesis is to examine how young womens sexuality is described in Swedish youth novels. The analysis is based upon eight books of which four were published during the period from 1970 to 1975 and four books were published during 2000 to 2005. The theoretical framework is based on a gender theoretical perspective where Yvonne Hirdmans theories about a gender system and Ylva Elwin-Nowaks and Heléne Thomssons ideas about gender construction are crucial. Also Anthony Giddens theories about sexuality in the late modern society are used, where the plastic sexuality and the pure relationship are central ideas. The method is based upon textual analysis, and a model of analysis is constructed with its basis in the theoretical attempt.

Då mängden information bara ökar, så ökar även behovet att ha åtkomst till informationen lättillgängligt. Detta skapar då ett behov för ett gränssnitt som kan söka bland informationen. I detta arbete har det undersökts om en implementation av Vector Space Model ger mera relevanta resultat jämfört mot en enklare implementation som inte baseras på Vector Space Model. Sökningen utförs i en relationsdatabas med ett inverterat index, databasen fylls med data ifrån internetforumet Stack Overflow. Genom att bygga en sökmotor som returnerade två olika resultatlistor för varje sökning så fick tio användare testa och utvärdera resultatens relevans.

This study is intended to identify which factors that influence the success of initiatives in Customer Relationship Management, usually abbreviated as CRM. In the course of this study we have been in contact with forty-two companies operating in Sweden within eleven different sectors in order to find out how they operate regarding CRM initiatives, particularly initiatives within marketing and promotions. Against the data collected during the study it was concluded that the companies working with CRM believed that the CRM initiatives resulted in higher profitability and created more loyal customers. At the same time it was evident that the companies had different views on CRM as a method and its benefits. The majority of the companies could not present any tangible results from CRM-initiatives. It was also revealed that decisions regarding CRM initiatives were based on subjective assessments and without theoretical foundation.

The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.

The aim of this project was to develop a numerical model simulating the global transport of air pollution. The model currently used by SMHI, the Swedish Meteorological and Hydrological Institute, was intended to perform such simulations at regional scales. However, the usage of a grid based on longitudes and latitudes makes this model work poorly in global simulations. The problem with this grid is that the nodes are concentrated near the North and South Poles. Due to this characteristic, the Courant, Friedrich and Lewy-condition for numerical stability puts a sharp bound on the timestep length.

Recently, the IASB and the FASB initiated a joint project to determine which companies that could be defined as investment entities and thus subject to an exception from IFRS 10 Consolidated Financial Statements. The first draft, ED/2011/4 Investment Entities, was published in 2011 and included six criteria that a company must meet in order to be classified as an investment entity. Based on academic theory, the fact that the IASB and the FASB published a joint proposal is interesting for several reasons. Traditional accounting theory tends to distinguish between two different approaches in standard setting: principles- and rules-based. The IASB is considered to have a principles-based approach, while the FASB is considered to have a rules-based approach.

Trust is a concept used throughout our daily lives. We give trust to friends, colleagues and strangers. We also give trust to the technical artifacts we use in our everyday lives. We must also rely on the services we use to work the way we expect them to. There is plenty of research on trust in e-commerce and online banking on website based platforms.

Vad krävs för att en person ska anses som ?skäligen misstänkt? och hur påverkar det polisers och åklagares arbete? I följande rapport har vi gjort en granskning av begreppet ?skälig misstanke?, vad det innebär, hur bedömningar av omständigheter runt detta begrepp görs och vilka beslut om tvångsmedel som kan tas därefter. Vi har utgått från litteratur, lagtext samt JO´s avgöranden. För att få en bild av huruvida avsaknaden av en definition av begreppet upplevs som ett problem hos polis och åklagare har vi även hållit några kortare intervjuer. Trots avsaknaden av en klar definition på begreppet uppfattas detta inte som ett problem enligt de vi intervjuat.

The aim of this Masters thesis is to, through user studies, analyse whether Carol C. Kuhlthaus information search model is applicable in a Swedish school. Furthermore, the guidance that the students may receive from the teacher and/or school librarian is analysed. Answers are sought to the following questions: · How do the students perceive their information seeking? · How do the librarian and/or teacher support the students during their information seeking process? The study is based on a qualitative method of approach, through interviews with four informants: a librarian, a teacher and two pupils.

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.

This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.

Business Process Modelling Notation (BPMN) is a way to graphically draw a diagram of a business process. A BPMN diagram consists of several so-called flow objects. These are interconnected in the graph through sequence  flows. BPMN models are merely graphical representations of business process and there is a need to simulate these diagrams for different purposes. The simulation that now is available for BPMN is that the model is evaluated by checking if it is correct.
