Projektet avser att undersöka vilka fördelar ett mindre familjehus kan dra av ett kombinationssystem med bergvärme och en uteluftkonvektor vid byte till en mer effektiv bergvärmepump. Uteluftkonvektorn är ett komplement till det befintliga borrhålet som är underdimensionerat mot den nya bergvärmepumpen. Under sommarhalvåret drivs utekonvektorn för återhämtning av hålet. Vid de varmaste dagarna på året återladdas även borrhålet av utekonvektorn.I detta arbete undersöks hur den årliga värmefaktorn och temperaturen i borrhålet påverkas av en kombinationslösning jämfört med att endast använda energibrunnen. En analys gjordes på hur husets effektbehov varierar under ett år med hänsyn till svensk byggnorm under 1980-talet, då huset byggdes. Från denna information kunde de olika driftfallen undersökas och fastställas.

This study has been carried out in cooperation with Unilever and partly with the EC founded project, Smartdoc IST-2000-28137. In areas of statistics and image processing, both the amount of data and the dimensions are increasing rapidly and an interactive visualization tool that lets the user perform real-time analysis can save valuable time. Real-time cropping and drill-down considerably facilitate the analysis process and yield more accurate decisions. In the Smartdoc project, there has been a request for a component used for smart filtering in multidimensional data sets. As the Smartdoc project aims to develop smart, interactive components to be used on low-end systems, the implementation of the self-organizing map algorithm proposes which dimensions to visualize.

Denna undersökning syftar till att undersöka och utvärdera den agila projektmetodiken med inriktning på Scrum. Vattenfallsmetoden berörs även med avsikt att tjäna som kontrast till agil projektmetodik och Scrum. Att arbeta utefter en specifik projektmetod eller anamma ett agilt förhållningssätt kan bidra till att rätt produkt utvecklas och att undvika att projektet misslyckas. Undersökningen baseras på tre grundpelare; litteraturstudie, intervjuer och undersökning av befintliga studier. Dessa ligger till grund för de resultat som presenteras och diskuteras i uppsatsen med avsikt att kartlägga förekommande fenomen i projekt bedrivna efter en agil metod.

This master thesis is looking into the stories on the internet forum www.resedagboken.se. The stories of Swedish teenaged exchange students in the U.S. are studied and the main purpose is to see both what they are writing about and the reason for why they are spending their time writing down their experiences in a public forum.Even though most of the teenagers here are writing with a specific audience in mind, all the stories are free to anyone to take part of and this causes a difficult position for the teenagers who often seem to forget the public point of view when they are telling about their personal lives.The study is divided into two parts. The first one looks into the content of the stories and the other one focuses on the storytellers and their reasons for writing. The teenagers are writing both a lot about their everyday lives in their new environment, but also a lot of things to keep in touch with what their friends and family in Sweden are doing.

To have someone to talk to and exchange ideas with was also mentioned by the informants as a vital part of feeling support in their work. From the Antonovskys theory, a sense of coherence, and Goffmans views of the society, we also find that the larger part of our informants feel a high sense of coherence and that when they have to adjust to their different caretakers they play different roles..

Facial expressions are a part of our body language that helps us to clarify the verbal communication between humans. We use our facial expressions every day, both consciously and unconsciously, to express emotions and attitudes depending on the situation. The hypothesis of the study is: Given a facial expression, how well can Microsoft Kinect, as an input method, determine a person?s feelings with the two algorithms Naive Bayes and Sequential Minimal Optimization? The feelings are limited to happy, sad, surprised and disgusted. With the help of Kinect, a person?s facial data, both coordinates of the face and parameterized data, were saved and used for machine learning.

Some researchers claim that we are witnessing the advancement of becoming a network society, and in spite of the different problems associated with the network form of organization, many cities still choose to engage in different types of networks. On account of that the aim of the study is to examine which expectations Swedish member cities of the network Eurotowns might have, and if their actions in the initial period of engagement in Eurotowns mainly could be explained by ?Logic of Consequentiality? or ?Logic of Appropriateness?.A qualitative research method was used and a major part of the empirical material consists of the information given by the interviewees.Regarding the expectations Swedish member cities have on Eurotowns, the result showed that five main areas could be identified mutual resource exchange, activities, breadth, security and meeting place. The results also showed that the actions of Swedish member cities may vary between ?Logic of Consequentiality?, ?Logic of Appropriateness? or a combination of the both logics.Furthermore the study also provides empirical evidence supporting the previously theoretical criticism expressed regarding the central assumption that the strategic actions of an actor can be regarded as a direct consequence of the mutual resource dependency..

This study is about the potential advantages as an investment option in a portfolio. The study shows that the incorporation of bitcoins in a portfolio, even to a small degree, gives significant increases of both risk and return. The different studied portfolios sharpe ratio rises, which in turn shows that the risk reducing return increases when bitcoins is used as an investment option.This study is based on Virtual Currency, Tangible Return: Portfolio Diversification with Bitcoins by Brière, Oosterlinck and Szafarz. The authors of this study have compared their own results with the study mentioned and seen its similarities and differences. The study investigated a total of eleven different assets percentage return over 192 weeks ranging from July 2010 to March 2014.

This thesis explores some issues regarding estimations of the cost of capital on the Stockholm Stock Exchange through reverse engineering of the Residual Income Valuation model and through usage of the Capital Asset Pricing Model. Previous studies are in conflict of whether the risk premium changes considerably over time or not. Furthermore, the risk premium estimated by CAPM tends to be fairly stable. In this study, reverse engineering of the cost of capital implied by analysts? forecasts shows a significant difference in the risk premium over time.

Since January 1st 2005 all companies listed on a regulated stock exchange within the European Union are required to present their financial reports in accordance with International Financial Reporting Standards (IFRS). The intention of the introduction of IFRS is to achieve international harmonization of accounting rules in order to make financial reports more comparable between companies from different countries. The purpose of financial reports presented in accordance with IFRS is to provide information that is useful to the users of the information. The aim of this paper is to investigate whether the information regarding goodwill and the goodwill impairment test, presented in accordance with IFRS, in fact is useful to a specific group of accounting information users, namely equity analysts. An empirical study is conducted, based on interviews with seven Swedish equity analysts.

This paper seeks to investigate whether there is a positive relationship between bonus as a part of total executive compensation and lower accounting quality among Swedish companies. In this study, accounting quality is defined as the degree by which a company's earnings are subject to earnings management. To detect earnings management accrual-based modified Jones model is applied to companies listed on the Large-, Mid- and Small-Cap lists on the Stockholm stock exchange during 2011. We find a statistically significant positive relationship between bonus as a part of total executive compensation and lower accounting quality. Thus, in line with prior research, our results suggest that managers, interested in maximizing their bonus, will select income increasing accruals to manage earnings upwards.
