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.

Music affects us humans. Marketing has long made use of music as a means to enable customers to identify with a brand, and thus increase sales. The Influence of music is obvious, but can you use this on students, and how effective is it to use in a classroom?I will answer the question: how does soft music provide reassurance/create a harmoniums learning environment at the beginning of a lesson?By observing how students react and behave to the playing of soft music. My aim is to create different strategies that teachers can effectively use to get students to ?jump in? to their lessons without wasting 5-15 minutes of class time.Professor Lennart Grosin conducts research into what is in Sweden called PESKO.

During spring 2012, six students at the Royal Institute of Technology in Stockholm carried out agroup project in the field of mechatronics as part of the thesis for the bachelor degree. The resultwas a robot with active balancing and the purpose of this report is to describe the development,manufacturing and problems that arose during the project. The finished robot has two wheelsmounted in line with each other, like a bicycle. Measurement data from an accelerometer and agyroscope are used together in a complementary filter for determining the angle from the verticalplane. For balancing, a PID controller was used to control the rotation of a reaction wheel, whenaccelerating causes a straightening torque.

Syftet med studien var att ta reda på om det går att predicera medarbetares organisationsengagemang utifrån organisationskommunikation, såväl mellan chef och medarbetare som medarbetare emellan. Detta gjordes genom att 118 medarbetare fick besvara en enkät bestående av delar från Communication Satisfaction Questionnaire (Downs & Adrian, 2004). Studiens huvudresultat visade att organisationskommunikation delvis kunde förklara variansen i organisationsengagemang. Resultaten diskuteras i termer av hur och varför organisationer som har en upplevd god organisationskommunikation, både mellan medarbetare och chefer och medarbetare emellan, skapar ett starkare organisationsengagemang hos sina medarbetare..

In connection with the property crises in many countries, caused by the financial crises, people are now more aware of the risks involved in poor property-investments. The unusually cold winters along with extreme prices of electricity in Sweden in recent years has also contributed to increased interest in energy-efficient buildings.The process of developing a modern family home in Kiruna, Sweden is presented the first part of this paper. The house has been designed to withstand very high stresses from snow, low energy consumption as well as a high standard of living comfort. Aspects of the house covered here involves everything from construction, heating and ventilation to sanitation. Each of these areas is presented based on their underlying, scientific methods or theories.

To identify the underlying forces behind a product hype is difficult and the findings often seem random and unclear. To create a better understanding behind the affecting mechanisms would consequently be a valuable addition to the surrounding research area. The purpose of this paper is to understand if there exist common denominators between different product hypes and in such a case, which these are and how they function. By conducting a case-study on four products which have enjoyed immense sale success on the Swedish market, the possible presence of structural resemblance will be analyzed. From the study we can conclude common denominators such as the presence of an underlying trend and an overbalance of indirect decision basis do exist.

Over the last decades there has been a steady increase in the representation of women on the political arena. Despite of this there are still fewer women in comparison to men in political organs particularly at the municipal level. It is therefore of great importance to examine which different factors that tend to effect the female representation at this level. Doctor of philosophy at Umeå University Jessika Wide presented in a study from 2000 that the share of women in the municipal councils tended to depend upon cultural, socio-economical and political factors. Other scholars also mean that women have specific interests and therefore are more represented in some areas.

The essay discusses how to look at a equality plan of a academic department experiences the, gender equality in general and how power is portrayed from a gender perspective in the academic department. Through the use of qualitative interviews and a short survey the results have shown that few of the staff members have knowledge about the equality plan and few are familiar with its contents. Furthermore results show that the academic department is run hierarchyilly and that both vertical and horizontal gender segregation exists.The climate at the academic department is characterized by the will to work with gender equality but so far there have only been few exercised or planned efforts to do so. The gap between theory and practise is wide, the will to be seen as an equal academic department concerning equality of men and women seems important. The conscious or unconscious strategy of covering up the real gender equality seems to be done by focusing on the numerical equality..

The competition for the beach promenade in Helsingborg was announced in 2001 and was arranged by the city of Helsingborg. My contribution to the competition represents the main part of my thesis in the Landscape Architecture Programme. The competition entry is based on the concept of crossing screens of vertical elements which connect the pattern and structure of the city to the beach and the water. The different materials and designs of the screens relate to the various characters of the different parts of the area and they form a sequence and uniting theme along the beach. In addition to the competition entry which was made in 2001, the thesis contains a second part, made in the spring of 2006. It consists of an Introduction with the competition programme and a description of the starting points, a part called Method where the process is described, and the Conclusion with reflections on the competition entry and the process where I also introduce and comment on some other projects which in different ways have are connected to my concept. .

Parallel imports often lead to lowered prices and is therefore regarded as good from a consumer's point of view. From a business'point of view this is not always the case. When do parallel imports occur? Is it possible to prevent parallel imports to protect an introduction of a product in another member state? The purpose of this thesis is to present situations where parallel imports occur and to see if it is compatible with competition law to prevent parallel imports. Furthermore I will analyse the future development after the group exemption of vertical restraints enters into force in June 2000.

This degree project was conducted in collaboration with Gremo AB located in Ätran.The aim of the project was to develop a solution to secure quality and to help assemblingthe locknut holding the vertical hinge on the harvesters and foresters from Gremo.At this time the nut is assembled manually by the aid of an overhead crane. The nut istightened differently from time to time, and there was no specified torque to which it istightened. Another present problem was the locking washer which sometimes getsdamaged during assembly, when this happens the procedure has to be started over fromthe beginning. The current assembly procedure is very time consuming and lengthy forthe employees.Our task was to design a machine that could tighten the nut to a specified torque with amargin of error of ± 3%. The assembly procedure will be held simple and the timerequired at a minimum.The project started by developing several principle solutions, the one solution that bestmatched our specifications were developed to a primary solution.Today we have started manufacturing and assembling our prototype.
