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.

A growing interest for the climate and the environment has led to an increased interest forenvironmentally friendly and renewable energy sources, such as biogas. Planning new biogasplants requires a decision basis including facts about approximate amounts of biogas possibleto produce at the plant. The purpose of this thesis is to develop a model that calculates theapproximate biogas and digestate production from a planned or existing biogas plant.Developing the model required a literature review and studies of calculations concerningbiogas and digestate production performed by WSP Sweden AB. As a complement to themodel development, facts about substrates for biogas production were compiled through aliterature review. In addition the methane potential from selected materials was determined bybatch experiments.

This report describes a study aimed at uncovering flaws and finding potential improvements from when the modelling tool EAAT is used in conjunction with the modelling language CySeMoL. The study was performed by developing a framework and applying it on CySeMoL and EAAT in real life context networks.The framework was developed in order to increase the number of flaws uncovered as well as gather potential improvements to both EAAT and CySeMoL. The basis of the framework is a modified version of the Quality in use model from ISO/IEC 25010:2011 standard. Upon the characteristics and sub characteristics of this modified model different values for measuring usability where attached. The purpose of these values is to measure usability from the perspectives of both creating and interpreting models.

Organisationer och personer runt om i världen blir alltmer beroende av olika former av IT-stöd. För att effektivisera arbetet skaffa sig organisationen nya system eller försöker förbättra det redan befintligt systemet. En användare kan reagera på olika sätt vid införandet av ett nytt system beroende på olika faktorer hos systemet eller personen. Jag studerade ett komplett Care-system som används inom äldreomsorgen. Ett Care-system kan bestå av en webbapplikation inklusive digitala och mobila verktyg.

The Swedish public inquiries and most of the political science advocate reforms in the spirit of participatory democracy to strengthen the democracy. Although it is striking how limited and narrow the scientific documentation is in analysing the effects of participatory democratic reforms. Still, many of the local governments in Sweden are reshaping their organisations according to the participatory democracy model. Is it a trend and a symbolic action or a veritable action of good-will of the politicians?The paper argues that the idea of participatory democracy has become popular and widely spread.

In 2010, SAS received the "On time performance service" award by Flightstats. This award was an affirmation of long-term work, both in projects and as an ongoing process, which the company sought to systematically improve punctuality on its flights. The extent to which SAS followed the values and the underlying theories of the cornerstone model for total quality management was the main issue in this essay. Whether there are conditions for the company to get even further by working in other ways was also investigated. In addition, the importance of punctuality in relation to customer satisfaction was discussed.

Purpose: To investigate if Altman´s Z´-score model, which calculates financial distress, can be applied on companies established in Sweden and if the financial crisis in 2008 made previously healthy companies go bankrupt.Methodology: Quantitative studies with a positivistic foundation. Empirical data will be collected in order to examine if there is generalizability among the studied objects. Conclusions will be made by comparing the empirical data with the theoretical foundation. Financial distress in firms will be measured.Theoretical perspectives: Altman´s Z´-score model, designed to predict financial distress in private firms.Empirical foundation: A selection of 93 private firms that have gone bankrupt in the years 2008, 2009 or 2010. The firms selected all have a turnover that exceeds 20 million SEK.

Mass distribution with techniques as multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.

In recent years, Information Technology (IT) has gained more importance in workinglife. More and more organisations has shown an interest about how technology can beused to manage the competence of the employees, and how IT can contribute to thedevelopment of the organisation. In order to achieve this, there is a need for suitabletools to support this process. Even though the implementation of competencemanagement systems (CMS) is a highly up to date question for many organisations,there is a lack of scientific reserach concering this area. This study will contribute tothe research area by examining how CMS is used by employees in daily working life.The manager and the employees in a healthcare organisation in Sweden were observedduring appraisals in order to observe how they used the CMS to evaluate competence.The appraisals were considered a suitable place for studing CMS in use within anorganisation.By using theoretical perspecitves such as the Sociomateriality and Situated Learning,the study can contribute to the knowledge of the entanglement between technologyand working practice.

This degree project has been carried out by Carolina Rapp and Jenny Tauson, students at Innovation and Design Engineer program at the Faculty of Technology and science at Karlstad University.
