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.

Background: Acquisitions are a well-known method for increasing company size and strength on the market. But to reach the targets set, more than just a positive economic calculation is required. An atmosphere that supports the company's integration is needed, for which it is of great importance for management to understand the underlying sets of values that exist in the organisation, and to take into consideration the way they might become an obstacle or a tool for a successful integration. Purpose: The purpose of this thesis is to explain and understand how cultural change occurs and how it affects the employee, as a smaller company is bought and integrated into a larger organisation. Procedure: The analysis is based on theories on organisational culture and organisational change.

This degree project investigates how elk, roe deer, red deer and fallow deer can affect an estate in Östergötland. The inventories performed within this project, were completed on an estate in Selesjö, northern Östergötland. This property is used to demonstrate wildlife management. The methods used in this study were originally developed for areas larger than individual properties. Three inventories were completed in the study. These included the recording of the number of droppings and the amount of eaten pasturage, as well as the level of damage on young trees.

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

Law and regulations regulate the auditors? independence. An auditor should not only be independent in general, but independence in fact and independence in appearance. However, the regulations do not specifically describe how to act independence. It is the concerns of the auditor were he puts his limit for the independence.

The aim of this study was to investigate how selected municipalities? use social media, with a focus on how they are working to increase the dialogue between municipalities? and residents. To answer the purpose of the study three questions has been formulated: how do the communicators use social media in their daily work? What opportunities and challenges are the municipalities? experiencing with Facebook? How do they work with Facebook to increase dialogue with citizens?The theories that has been used in this study is Cutlip?s and Grunig?s public relations theories, Shannon and weavers communication model, Cutlip?s and Heath?s theory of issue management and Jenkins theory of convergence culture. The method that has been used in this study is qualitative semi-structured interviews and the analysis is done with a thematic text analysis.

The purpose of this thesis was to analyse, model and finally generate dynamic vehicular motions in a train. The objective with the analysis was to find important motions for a realistic train experience. The motions from the analysis were then weighted against possibilities for generation in a motion platform.A dynamic motion model was created to model the selected motions. The model was implemented in a simulation environment, more specifically MATLAB/Simulink. The simulation environment was used to simulate the model and to generate outputs to control a motion platform.

AbstractThe purpose and vision for the municipality of Torsby are to connect with a younger population in the municipality by the year of 2012.This study is a qualitative survey of the target group ?the young ones? within the municipality of Torsby, which is the population between 17?35 years old.Because of the size and the different intrests between the individuals in this group it has been divided into three smaller groups.? High school students, 17-19 years old.? Returning seasonal workers, 20-26 years old.? People who has moved to Torsby and are now living in the municipality, 27-35 years old.The results of the study show that all the respondents believes that with the right communication channels a positive and strong communication between the municipality and the target groups can be reached. The message and the significance of the message are as important as the communication channels and all the target groups together would like to see a wider range of leisure pursuits that will suit the respective target group.The analysis and the results also show that the communication with the target groups should come about in different ways to be successful, both when it comes to fundemental reasons and choices of communication channels.The two youngest target groups has an adjacent and a similar need of well-founded and entertaining communication and information to rach a long-term result.The older group needs communication that will give them opportunity to reflect and concider the message, which means that the municipality of Torsby needs to adjust both the message and the communication channel for a quicker respons. This target group is also in need of further studies so the municipality of Torsby succesfully can plan a more detailed communication, this because the target group is a less homogeneous group than the two other target groups..

Predicting corporate failure is an increasingly important topic in the world of economics today. This paper, with the help of the credit ranking company Syna AB, aims to investigate a few different statistic strategies to do just that. This task is accomplished by using a data material of 250 000 Swedish companies divided into two subsamples. The first sample is used to develop the model and the second as a validation sample. The model developing sample holds 160 000 companies divided into five different subgroups based on size and age.

I have done a follow up study of the restoration of two rivers, Röälven and Grundan, in order to evaluate the effects of the restoration on the endemic population of trout. Both rivers have been used for timber floating during many years throughout the 20th century, and because of this, had all obstacles such as rocks and wood parts removed. In 2004-2005 both rivers were restored, and rocks and wood were put back into the rivers. Spawning grounds were created and boulder dams were constructed to promote the streaming water. The result showed that the trout population of both rivers increased after the restoration, but also that the trout population of Röälven increased more than that of Grundan.

This study aims to investigate the domestic and work organization at the mansions located in the south of Västmanlands county years 1705-1849. The study takes into account the manors' size, ownership, owners' status and social changes. The study includes both large manors with noble owners and smaller manors with bourgeois owners.  The study examines how the households were formed, how they changed over time and how thet may have links to the Manor's ownership and size. The organization of labour is studied on the basis of how it changed over time and what it may have links to the owners ' status and the manors size. The focus is to answer how the connection was between household size, its composition, organization of labour and the owner?s status in the society.  Also if a difference can be seen between the strategies of the noble owners compared to the bourgeois owners..

The stakeholders for requirements elicitation need to be identified at an early stage and their knowledge is the basis for what is to become a requirements specification. Just because a stakeholder holds a lot of expertise and knowledge it does not mean that the stakeholder can communicate the knowledge in a clear way. Validation of knowledge means that knowledge is valued and recognized in a structured way. People and organizations can evolve by exchanging knowledge, experience and skills.  The purpose of this study is to increase the understanding of knowledge management between requirement elicitation and external stakeholders.

This project consists of an adaptation, trial and evaluation of a model for practicing. Based on prior research I created a model aiming mainly to raise a musician?s self- awareness around the different parameters a performance consists of. An additional wish was for it to simultaneously assist the musician in monitoring his or her progress. With video recording and self-evaluation as the two main parts I tried the model by using it over a period of three months.
