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.

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

The thesis deals with three document retrieval models based on logic: the Boolean model,the fuzzy model and the Van Rijsbergen model.In Chapter 1, the author presents the purpose of the thesis. This is to give the logical foundationof the models, to describe them and to examine them critically. In Chapter 2, some importantnotions in document retrieval are presented. Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.

AbstractThe main aim of this study was to investigate if four humour styles, affiliative, self-enhancing, aggressive, and self-defeating humour can be related to all five dimensions of the Big Five Factor Model of personality and study if gender has any influence on those relation-ships. A survey questionnaire was distributed among 72 individuals from Kalmar County, in the South-east of Sweden. There were 42 women and 30 men. A humour test questionnaire, Humour Scale Questionnaire (HSQ), with 32 items was used and the Big Five Factor test with 40 items was used for personality test. The results showed that men have a more aggressive humour than women and that the older we get the less affiliative and self-enhancing humour we have.

The aim of this thesis is to examine how librarians are workingwith the selection and purchase of feature films in Swedish publiclibraries. I was interested in examining the underlying reasonsbehind the selections. I chose to focus on how librarians areworking and reason about the library´s film collection.The purpose of my study is to answer the following questions:? How are librarians working with selection and purchase offeature films in the public library?? What factors motivate librarians´ selection of featurefilms?? What do librarians reason about the public library filmcollection?To answer these questions I performed interviews with sevenlibrarians in five different public libraries. The results of theinterviews have been analyzed on the basis of the theories andtheoretical model of Sanna Talja.

Studies have shown that politicians are significantly more likely to become victims of violent crime than other citizens in Sweden. In fact increasing political rank and engagement are directly proportionate to increased risk for violence. Threat towards politicians is not only dangerous to the individuals involved but also to the democratic system as a whole.Political scientists the world over have done a lot of research on democracy, but I have been unable to find a single method or theory that examines how violence, threat and harassment affect political leaders and democratic systems.The aim of this study is to expand the existing model made by Tommy Möller, professor in political science. In his model he presents 11 factors that affect political leaders ability to act. My aim is to develop his model by adding a 12 th factor ?violence, threat and harassment?.

The purpose of this essay is to try to understand the relationship between the structures of modern working life and the development of burnout. By using the method of qualitative interviews we wanted to see if the Effort-Reward Imbalance Model could be applied to the data we had collected. Two questions have been highlighted in our research:        ? Is it possible to establish a relationship between the structures of modern working life and the development of burnout among the subjects interviewed?  ? Is it possible to explain the development of burnout among our interviewed subjects through the Effort-Reward Imbalance Model?    Our theoretical frames are the general theories of the modern society and the modern working life as developed by Anthony Giddens, Ulrich Beck and Zygmunt Bauman. We have also used Johannes Siegrist?s medical-sociological Effort-Reward Imbalance Model (ERI-Model).

The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.

This study analyzes 66 Swedish actively managed mutual funds investing in the Swedish stock market during the period 2005-2014. The purpose is through pooled data regressions analyze the relationship between both the mutual fund?s annual fee and risk-adjusted return to the fund?s characteristics. The characteristics of the study are the size of the fund's assets, age, if the fund is bank managed or not, Tracking Error, and standard deviation of return.By using the performance measures of CAPM, Fama and French 3-factor model, and Carhart?s 4-factor model monthly risk-adjusted returns are created for all funds over the period.

According to TCO (The Swedish Confederation for Professional Employees) the worst threat to the Swedish welfare is that so many people because of bad health and unemployment are not a part of the labour force. If Sweden could make the number of people with health and unemployment problems half the size as today, the GDP would increase with more than five percent. In real money this means 110 billion Swedish kronor a year. According to SCB (Statistics Sweden) the difference between women?s and men?s absence owing to illness should be investigated more closely in order to get at better understanding of the problem.

We have chosen to focus on the meaning of long-term income support dependency regarding health, goal setting and motivation for the recipient of economical aid. We have chosen to use semi structurized interviews to achieve our goal of reaching the clients experience of long-term income support dependency. The study consists of interviews of six clients whose answers have been analyzed through appliance of Kielhofner´s Model of human occupation, Scheff´s Shame in self and society.   Our results show regarding, 1) the factor health that long-term income support dependency may elevate the risk of illness and less experienced options of possibilities to act. 2) regarding the factor goal setting, that goals may be inefficiently used during social work with long-term income support dependent clients and may result in a disorganized relationship between client and social worker in the sense of making the parties pull in opposite direction. 3) regarding the factor motivation, that long-term income support dependency and the living with the emotion of shame elevates the risk of maintaining a negative image of oneself that limits the willpower to assimilate new knowledge and/or skills.
