This report describes an investigation of the indoor climate in two different workspaces. Since we a big part of our lives are staying indoors in artificial environments, and more particularly in our workplaces, we think it would be interesting to do this investigation. The technical solutions for air treatment systems began with simple natural systems without fans and where the thermal rise of the air applied. In modern time is technical air treating systems used to take care of the fresh air supply. This type of units can supply filtered air with the right temperature to the building. Well-functioning ventilation is essential to bring clean fresh air to the room and effectively remove impurities without sound- or draught problems. The indoor climate is relevant for the output capacity.

A large amount of our time is spent indoors in an artificial climate. To make the experience pleasant there are requirements on the ventilation and the heating system. At the present time the most common form of heating is a radiator system complemented with a ventilation system. A ceiling heating system with combined heating and ventilation can replace the two separated systems. The benefit with a ceiling heating solution is that it saves space since the radiator system is no longer needed.

Background and Problem: The lack of auditor independence is discussed being oneof the reasons to scandals such as Enron and HQ. A pricing strategy that has beendebated impairing auditor independence is low balling. To win a new client in atender process, audit firms supposedly offer an audit fee below cost and then increasethe fee the following years to recover the initial loss. The auditors? future financialinterest in the company due to the initial loss is by some believed to impair auditorindependence, which makes low balling in Sweden a relevant phenomenon to study.Aim of study: This thesis aims to explain if low balling exists on the Swedish auditmarket and if the size of companies affects the results of low balling.Methodology: To achieve the purpose of this thesis, a statistical study wasconducted.

This report describes a project carried out in cooperation with Klippan Safety AB. The purpose of this project has been to develop a product that facilitates the living area in a truck cabin for the customers. To be able to develop, in a structured way, that kind of product, the project has been based on different product development theories. The project contained of following parts: marketing research, product generation, product evaluation and prototyping. After information from the marketing research and discussions with the company, the decision was made that the task was going to consist an improvement of the existing product referred to as 'the comfort module'.

This study investigates the effects that commercial computer games have on young individuals social comfort and learning progress. As a systematic study of literature, scholarly articles have been analysed in order to illuminate the positive as well as negative effects on social comfort and learning progress that may come with playing computer games. The social effects have mainly been discussed with role-playing games, such as World of Warcraft, as starting point, while the learning effects have been coupled with strategy games, such as Civilization IV. The study does not simply declare how these games can be good for these factors, but also in what respect computer games may prevent the development of young individuals socials skills and learning progress. The study showed that in spite of perpetual prejudices against computer games in the technological age, computer games might actually be good to use as a tool in order to authorize the development of young individuals regarding learning and social aspects.

The purpose of this thesis is to investigate the price effect on the initial day of trading of IPOs and the price effect on the announcement day of SEOs on Stockholm Stock Exchange. A second purpose it to conduct studies on which factors influencing the price effects and if these factors can be explained by the same fundamental ideas. Theories regarding capital structure and the pricing of IPOs and SEOs are covered. The capital structure theories involve; Miller and Modigliani's cost of captial theory, Static Tradeoff Model and the Pecking Order. The Efficient Market Hypothesis is presented and previous theories are investigated.

Together with Attends in Aneby a thesis of 15 ECTS (credits) have been undertaken. The assignment was to develop a new incontinence product for single use. Users of the product value comfort, flexibility, softness, comfort and a discreet product. Users are for individuals with incontinence problems that usually receive the products via prescription. The product must also have an attractive price and good quality from the purchase / originator's perspective.Currently there are two models that Attends supplies, which the project intends to develop, (Slips / Briefs and Pull On's).

This paper is an event study on Initial Public Offering?s return behavior after the dot com bubble. Cumulative Abnormal Returns are used to measure the performance against a market index. The results suggest that the market correctly prices IPOs in the long run thus upholding the Market Efficiency hypothesis. Moreover, value weighted CARs show that large IPOs are more likely to outperform smaller IPOs, however in the long run there is an unpredictable pattern.

Upon marketing the system in Europe and the USA cost savings generated from reduced work force have been prevailing. Since the cost of labour is much lower in the Asia Pacific region other factors have to be stressed. The parameters of flexibility and quality assurance may however cover any initial investment in a production system. Our purpose is to value flexibility and quality in a manufacturing context, applied to DAS, in order to use it in investment calculations. In order to make an adequate estimation of different companies, due to problems associated with acquiring correct figures, the Key Success Factors needs to be examined so that the gathering of numbers can be conducted with more focus.

Purpose: The purpose of this study is to highlight what is perceived as- and what is not perceived as- supportive and comforting, by the sick child in palliative care, and by its family. Method: Systematic literature review in which only scientific articles from the years 2001-2010 have been included. Analysis: A method inspired by qualitative content analysis was used. Results: The analysis revealed five categories of what the sick child and its family experienced as supportive and comforting - and what was perceived negatively - in the context of palliative care for children. The results showed that it was very important to have competent, dedicated and compassionate staff that not only care for the child but also see to the whole family.

This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

The purpose of this thesis is to achieve a greater understanding of how the social workers at the family unit in one of Stockholm municipalities comprehend the work environment at the workplace. Our aim is also to find out how the work environment can affect the health of the social workers in the form of their wellbeing and comfort at the workplace. In order to answer our purpose we conducted interviews of all social workers at the family unit in one of Stockholm municipalities that describe how they experience the work-environment in the workplace and how it influences their health.  We have analyzed the interview material in a thematic analysis based on three theoretical perspectives; SOC, claim ? control - support and Human relations. We have also coupled the interview material to the background chapter in this thesis that describes how a good working environment should be structured.  The chosen method characterizes an abductive process.

Who would not like a profit of more then 95 % in a day? Investors in Sweden had thatopportunity, if they had bought a certain stock on the primary market and sold it on the firsttradable day at the Stock Exchange. Most of that profit fell into the hands of institutionalinvestors. The reason for this extraordinary profit was the underpricing of that specific stockduring its initial public offering (IPO).Our report aims to analyze the relationship between offer price, underpricing and theownership structure of stocks. Our investigation is based on all IPO?s on the Stockholm stockexchange during the years between 2000 and 2005.

Laboratory work is a big part of chemistry education in high school. During our student training placement we have noticed that the laboratory work is not fully utilized to develop students´ chemistry knowledge. This problem made us want to investigate how the laboratory work in chemistry could be set, to become more meaningful for students. We introduced two preparation methods, and examined the outcome of students learning experiences and their acquisition of chemistry knowledge. This was examined both through surveys and observation.

A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.
