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 develop a new business model for district heating and cooling firms which can contribute to a stabilization of the Swedish national energy system. The business model is developed for a district heating and cooling firm and is exemplified with Fortum Heat. The theoretical investigation around the topic creates a rigid base for following qualitative empirical studies. Osterwalder?s canvas for business model generation is used together with a Casual Loop Diagram to identify a number of business opportunities which stabilizes the national energy system.

The purpose of this study is to facilitate sustainable building by the use of BIM. The goal is to determine which aspects of sustainable building, which can be analyzed mainly with BIM tools, but also other aids.The study is based on literature studies and interviews. The literature review examines aspects important for sustainable building by studying environmental certification systems applicable in Sweden, as well as the BIM tools available on the market to analyze these aspects. The literature also includes the concepts of BIM and sustainability in order to provide a clearer view of its meaning. The interviews have brought the study's overall understanding of the industry and guidance on the subject.The results are presented in a table, where the aspects relevant to sustainable building are listed.

During the latter half of the 18th century, when concrete started seeing general use in modern cities, the use of different methods to give the concrete a finished surface texture saw use. One of these was using different methods of mechanically altering the surface using a slew of cutting and crushing techniques with mallet and chisel. This was done in order to hide the often dull and gray look of concrete, and allude to other more expensive and luxurious stones. The work would possibly have been done by experienced stonemasons, using much of the same techniques and tools they would have used while working natural stones. Or did they? This essay explores, through the use of traditional handcrafts and tools, the claim that the working of concrete surfaces can be done with the same tools and skillset as the working of natural stone.

REINERTSEN AS performs expansion and buckling analyses of pipelines using ANSYS, afinite element modelling and analysis tool. In an expansion analysis the pipeline is modelledwith thin?walled pipe elements called PIPE20 which allows plastic deformation. However, ina recent analysis the results retrieved from the PIPE20 element were incorrect for strainsabout 1 percent. One main issue was that the PIPE20 element overestimated the strains.The purpose with this Master Thesis was to become familiar with the theories and analysismethods used in pipeline design.

AbstractThe importance of good construction planning affects the final costs of the production and the timing of the project. Planning for building projects has been studied with the aim of identifying how three week planning appears in the construction industry today.A case study has been conducted in Navisworks Simulate to assess whether the software is suitable to connect the task schedule with the BIM model to create a 4D model. 4D models are used for performing 4D construction simulation to visualize the project. In order to use the benefits of the model, investment in equipment and software is required. This means higher costs for the companies.

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

An airline company that operates with its fleet needs to ensure that maintenance of a following and certain standard will be implemented. In this project we have sorted and divided the various working procedures of Malmö Aviation into Work Packs. These procedures are mandatory and must therefore be implemented in order to keep the aircraft airworthy at any time. Our task was to optimize and sort these working procedures by zone, panels, access and down time. We have created a maintenance program which Malmö Aviation can use and we have sorted their working procedures in B and C- Checks.Maintenance procedures that did not fit into our Work Packs have been gathered and sent back to Malmö Aviation for further inspection.This project has required a lot of extra reading in manuals and we have had a great insight into the complexity of a technical organization such as Malmö Aviation..

The goal of this paper is to provide a model for a sustainable electricity system to an island, in the Pacific Ocean near the equator.The method which has been used is to model supply and demand of electricity in the computer program Stella, through the creation of a dynamic system that balances them against each other. The result from the model will then be used to calculate the electricity price per kWh for the island.The result of the work is that electricity from solar energy is comparable with electricity produced from oil, if the oil pays for all its external costs, and the potential for pumped hydro storage plants is located. It also requires that consumers of electricity can be their own producers to avoid the expenditure of tax and reducing the cost of distribution. But since oil is a finite resource and has had a rising cost in recent years, while solar energy has had a declining cost, perhaps this will be a more competitive solution in the future.

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.

This study includes several purposes which are to describe the concept of working environment, explain who is responsible for its functioning and how the working environment should look like. Other purposes the study have is to investigate how the working environment is in both Swedish and the two investigated companies construction sites and to share some operators proposing measures for the shortcomings and problems that exist in the construction sector working environment. To achieve these purposes was a qualitative study made with unstructured observations, interviews and survey where three construction sites were observed. The result shows that the concept of the working environment cover many aspects and is essentially about the environment we live in and experience in our work and this environment can be both an indoor as an outdoor environment. In this work, the concept is divided into four areas; it is the physical, the ergonomic, the psychosocial and the chemical.

A mobile testing application using Unity was developed to analyse what impact button sizes and button layouts has on the accuracy of touch as well as the time to finish a labyrinth. This was tested on a Nexus 4 phone. 28 users navigated a small object through a labyrinth in which they collect keys to open the door to the exit. Each participant did the test 6 times with different combinations of button size and button layout each time, done in a random order. Hits, misses, completion time, order of button size and order of button layout was collected and then visualized using R.

The last decades the increased computerisation at the places of work has led to new physical loads in the working life and new demands on the working environment. The widespread usage of computers in the working life has led to more sedentary work and less daily movement.The purpose of the thesis is to develop a new product to a concept that in a low intensive and healthy promotional way will activate the body. The product will make a combination of healthy promotion activity and work during office hours possible and primary aims to those with a sedentary office work, which leads to that the body don´t get to be activated in the extent needed.Information has been gathered from studies already made in this area, interviews plus a study and an experiment. From the gathered information concepts and functional solutions has been generated and evaluated to result in a product concept.The thesis has resulted in a concept that consists of a work place unit where the user walks on a treadmill and works at the same time.A general conclusion which can be drawn is that the majority of persons that tested to walk and simultaneously work with a computor on the treadmill found this way of working attractive. Many were positively surprised and said that they would use such an physically activating work place implement if it was available at their place of work..

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

I have with this thesis sought to understand how chick lit could be useful in the classroom in the teaching of Swedish B-course in high school. Based on the model of critical literacy I am arguing that this genre would help to meet the objectives of the policy documents which, among other things, are to critically examine and analyze various types of texts.I have found that some of these texts could be used for analyzing and critically examine the ideological dimensions of texts and cultural heritage by the model of critical literacy, and also as a counterweight to the more traditional teaching of the canonical literature as a literary historical stuff that students should learn. I have also wanted to create a basis for discussions about literature in the classroom based on the chick lit genre. To do this I have, based on three themes and questions from the model of critical literacy, tried to focus on issues that might emerge from the ideological analysis and critical review. The model aims to deconstruct norms of society, and in the work of chick lit, I wanted to show how you could deconstruct norms around gender..
