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.

In order to respond to a more complex community planning with increased cooperation and public participation, a common language and a common model to be used as a base for the communication process is needed. The thesis behind this dissertation for a master's degree is that a virtual 3D planning portal would respond to this need. Why and how are explained and described through studies of communication- and perception theory as well as technology and recent research. The introduction concludes that a broad participation and a transparence towards underlying information are important foundations for the coming work with the model. The first four chapters of the theory part show the benefits of using natural signs in our mixed cultural society, instead of the more arbitrary symbols. Using visual landscapes for storing information is motivated by the flexibility of our visual memory and its ability to understand complex connections.

AbstractObstacles or opportunities? ? A study of the experience of collaboration of social welfare secretaries and school staff.The purpose of this study is to illustrate the importance of the work with children and youth through the joint efforts between different authorities. The study deals with the collaboration between the social services and schools in the Ludvika municipality. The objective of the study is to investigate how teaching personnel and headmasters in compulsory schools and the social welfare secretaries in Ludvika, experience the collaboration, and how this works. On the basis of the objective, we have formulated some relevant questions; To what degree are schools aware of the model of collaboration, which is the basis for collaboration within the municipality, and are there any differences in awareness between different categories of employees? Other questions deal with differences in how the social services and schools experience the collaboration, discrepancies between different schools in this regard and if the respondents? experience any obstacles and/or opportunities by the collaboration.Collaboration is, and has been, a pressing issue for a long time in the public debate.

Competence Portals are software tools that are intended to make it easier for persons that have had no previous contact to find and contact each other. The portals can address areas ranging from finding an expert within an organisation to the marketing of the competence of a region or a research centre to other organisations. The purpose of the thesis is to examine the necessity of Competence Portals in research-intensive organisations. Important characteristics of the information in such portals have been identified and used as a basis for recommendations regarding how Competence Portals could be designed. Furthermore, the thesis focuses on the task of finding a source of knowledge within an organisation.

Abstract This degree project examines how much carbon dioxide that emits during the construction phase of a road project. This is to make it possible to compare how the amount of carbon dioxide differentiates between traditional road construction and Swepave construction, which is PEAB?s alternative way to design roads. To make the comparison a calculation tool has been produced. To compare the amount of carbon dioxide emissions a reference project was needed.

As IT service departments in organisations are becoming more complex and customised, the indirect costs are increasing in relation to the total costs. The difficulty of fully estimating and identifying the spread of the cost in the IT service department is increasing. As a result, firms tend to budget the business unit as a total cost rather than as a spread of defined costs. In order to deal with this challenge an ABC calculation will be applied. The Time Driven ABC model will be conducted in OMX´s Servicedesk unit within the IT services.

The concepts of environmental scanning and Business Intelligence have gained increased interest over the last years in a number of different organisational contexts. The research in this field has mainly been dealing with methods and issues regarding organisation but the aim of environmental scanning, the forming of new perspectives, has been largely ignored. The purpose of this thesis is to study how Swedish joint-stock banks put environmental scanning and Business Intelligence into practice. First a literature study is made to create a background and to explain the different conceptions. Then I describe the different functions of the different services in Swedish joint-stock banks.

As the companies of today are good at protecting themselves against external threats, but are having problems with internal threats, we focused on how information can be protected from ending up in the wrong hands. First and foremost to protect information from employees who might steal it and sell it to another company. Since the security investments needed are connected to the financial costs of implementing them we have tried to create a balance between the investments needed and the cost of implementing them. The different kinds of protection needed are first and foremost protection to make data less accessable, passwords and traceability. While it is hard for us to estimate the amount of money a company lose by the hour when the production stands still, we have not been able to use any of the excising models to calculate the profit of installing countermeasures.

An information system is something that evolves over time to enhance the company that is using it. The technology for building an information system is also evolving. New methods and new programming languages make system development easier. As new technology breaks ground and the demands of a company?s information system grow, the company will sooner or later get to a point where a change in the base of the system is necessary.

The purpose of this study was to examine how the genrebased instruction applied in multicultural classrooms. My observations were carried out in three different classrooms, whit the educators constantly working on language development off the students. Two observations were carried out in Swedish, with a teacher of Swedish as a second language and the Swedish-teacher working with students together. In these two lessons in Swedish, I took away from Pauline Gibbons model, while the third lesson in civics I assumed from Eija Kuyumcu genre model. Both models are based on the Australian research around the genrebased teaching.

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

In today's producing companies, there is a high demand on early integrated productdevelopment. One way to facilitate communication between departments and collaborationbetween people and thereby enable early sharing of product information within the companyis to use PLM, Product Lifecycle Management.The CAD environment at Scania is at the moment being upgraded from Catia v4 to Catiav5. In this stage it is important that also the interacting computer systems in Scania?s PLMenvironment are adjusted and in the future join the development. Scania has an idea of howthese systems will be developed as the transition from Catia v4 to Catia v5 is being carriedout.

The role of small businesses is fundamentally important for the economic development in countries. Within this context, business incubation is used as an entrepreneurship development instrument to promote and support new firms in the early stage of their existence. However, research in the field tends to disregard the perspectives of incubatee entrepreneurs. The performed investigation is based on interviews with entrepreneurs from two different business incubators at Swedish universities. This study uses a Situated Learning Theory (SLT) as a theoretical framework, to examine the entrepreneur's experience of the learning environment in a business incubator.
