Business Process Modelling Notation (BPMN) is a way to graphically draw a diagram of a business process. A BPMN diagram consists of several so-called flow objects. These are interconnected in the graph through sequence  flows. BPMN models are merely graphical representations of business process and there is a need to simulate these diagrams for different purposes. The simulation that now is available for BPMN is that the model is evaluated by checking if it is correct.

This is a bachelor thesis that studies and discuss the question: How can we develop our individual narrative technique with sound design in a Swedish drama production? We have done research and empirical studies. We have analyzed movies to get an idea how we use the sound design in Swedish drama productions today. We have produced a movie that gives sound the biggest part. Key words: Swedish drama production, narrative technique, sound design .

The Goal with this Master of Science thesis is to expand the possible turbine efficiencymeasurements on an exhaust turbocharger. It was done as a part of the CICERO competencecentre. To feed the turbine with air a special flow rig has been used. Instead of loading theturbine by just restricting the compressor flow a docking system for an electrical dynamometer isdesigned to use the dynamometer as an additional loading source. By using an electricaldynamometer as loading device for the turbine, measurements are not depending on compressorperformance.A large part of the work consists in designing accessories for the dynamometer.

This project is a learning CD-ROM production aimed at first-time parents. It is using both sound and images, moving as well as non-moving. The purpose of the production is to be an interesting alternative to traditional books. We have been looking at similar productions like drivers license educational CD-ROMs and encyclopedias for inspiration and ideas on how to proceed. In order to give the content some dynamics, we've also added the element of 3D-animated sequences.

Att införa lean principer inom sjukvården är ett relativt nytt område. Landstinget i Gävleborg och Gävle sjukhus är intresserade av att korta ner sina vårdköer med hjälp av logistiska metoder och lean production principer. Detta på grund av att vårdköerna på bland annat urologmottagningen på Gävle sjukhus bara växer. Lean production är ett koncept som ursprungligen härstammar från bilindustrin i Japan och innebär att man strävar efter att göra mer med mindre. På svenska kan lean production översättas till resurssnål produktion och arbetet med lean innefattar principer som kunden i fokus, teamarbete och ständiga förbättringar.Syftet med examensarbetet är att ta fram en arbetsmodell för införande av lean principer inom sjukvården, då vårdköerna idag är långa och någon form av förändring är nödvändig.

The demand for biogas as vehicle fuel has risen sharply and there is a great need for increased production. A possible addition of vehicle gas can be produced by upgrading landfill gas which is formed by degradation of organic waste. This thesis investigates the potential of producing vehicle fuel from landfill gas in the region of Biogas Öst.In 2008, an amount of 32 million Nm3 landfill gas was extracted in the region. This level can be maintained for another ten years if the efficiency of gas extraction is improved. The annual production will decrease with time since landfills aren?t allowed to receive more organic waste.

This thesis calculates and compares the values of improved environmental quality due to future possible investment alternatives in biogas production facilities at Käppalaförbundets Reningsverk (Käppala Sewage Treatment Works) in an attempt to determine which alternative yields the highest such value. Käppala faces three investment alternatives for the usage of biogas. The alternatives are production of vehicle fuel, district heating and thirdly, heat and power production. Estimates of the value of environmental change are calculated for each of the three investment alternatives, and these estimates are then compared. The environmental change in question is the change in discharge levels of carbon dioxide (CO2), nitrogen oxides (NOx), sulphur dioxide (SO2) and particle matter.

When the storm Gudrun hit Sweden on the 8th and 9th of January, many recreational forests in southern Sweden blew down. For this reason there is a demand for new regeneration methods as to how these storm-felled areas should be regenerated and with what species. In this study the forest is divided into three areas: production, recreation/production and recreation. The first area is a forest with production as main goal and these kinds of forests are located a bit from the city. The second type ? recreation/production forest ? has two equal goals: production and recreation, and is located close to the city.

The Internet provides the common user with a variety of both traditional and non-traditional news sources, and a vast range of possibilities to contribute to the flow of information. By their participation in the production of information ordinary citizens can sometimes function as non-traditional news sources them selves and reach a potentially unlimited audience. The interactive nature of the Internet blurs the line between producers and consumers, and challenges traditional definitions of what counts as "news" as well as who qualifies as a "journalist". The main purpose of this thesis is to examine the potential consequences of this decentralization regarding the information behaviour of newspaper journalists and their perception of their professional role. The study consists of qualitative interviews with six journalists, employed by four of the leading Swedish newspapers, and a review of earlier research in the field.

The ISO standard ISO/IEC 17799/SS-627799-2 is a guidance for organizations to realize their information security goals. In spite of this standard, studies show flaws regarding information security in organizations. In particular flaws regarding overall view, knowledge and clear roles and responsibilities have been observed. The ISIT (Information Security Integrated Three level) model and its guidelines, developed in this thesis, help organizations to identify the required processes and procedures as well as the logical process flow. The thesis is based on theoretical studies and a case study within a multinational company.

Syftet med detta arbete är att undersöka hur dynamisk svårighetsjustering påverkar hur spelare värderar ett spels svårighet, presterar under en spelsession och huruvida de kan upptäcka ett system för sådan justering samt identifiera hur det fungerar.  Arbetet vilar främst på Robin Hunickes arbete kring dynamisk svårighetsjustering men vidrör även koncept som svårighet, flow och olika typer av svårighetsjustering. För att undersöka huruvida system för dynamisk svårighetsjustering påverkar spelande har ett plattformsspel utvecklats och speltestats i två versioner av en handfull respondenter, en version som justerar svårigheten i spelet dynamiskt och en som balanserats för hand. Resultatet från dessa speltester ger inga direkta stöd för att dynamisk svårighetsjustering får spelare att prestera bättre och tyder på att spelare vid en första spelomgång har svårt att identifiera system för dynamisk svårighetsjustering. Resultatet visar dock även på att mer undersökningar kan behövas på ämnet i framtiden..

Käppala wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic wastes such as restaurant waste and waste from water works. To decide the potential of both methane and biogas production from different substrates batch laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant waste.The batch laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

This master thesis is performed at Scania Axles and Gearboxes, a production plant located in Södertälje. Within the plant axles, gearboxes as well as central gears are assembled from components to finished products. All production is conducted on production lines, with a pre-determined rate, which is supplied with components by the material handling department. Since the production quantity and the mix of product variants produced on the production line is customer order-based, the number and type of components needed for production as well as appropriate staffing within the material handling department is difficult to predict. Scania is currently using a number of different resource planning tools for each material handling-department within Axles and Gearboxes to visualize the workload within the departments.

An old and well known problem in sawmilling is to determine which dimensions /products those are most profitable to produce. Existing optimization models maximize the value of the log. In other words, based upon the market prices of the dimensions the models calculate the best way to split the log. Yet there is a great uncertainty if the most well paid dimensions really are the most profitable to produce. The costs of the process from lumber to sawn products are hard to determine and are therefore often left out from the optimization process. In this study the economic contribution of different dimensions/products are analysed.

This project aims to investigate whether algae can be used for biodiesel production in Italy. Algaes are a good option since they are fast growing and do not occupy arable land. The aspects that have been considered are growing, harvesting, which algae strain that is most suitable, extraction of oil, the production of biodiesel and where in Italy this could be possible due to climate. Cost? and energy calculations have been made to investigate if biodiesel produced from algae would be profitable. During the production of biodiesel there are several residues obtained. When the oil has been extracted from the algae, biogas is produced from the residual biomass by anaerobic digestion and then the electricity that can be produced is supplied to the production of biodiesel.
