This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..

This study tests two financial valuation models empirically by valuing three stocks from three industries, with the purpose of studying how well valuation models work empirically and to make a forecast. The models which will be tested are residual income valuation and discounted cash flow. Nine stocks will be picked strategically from the Swedish stock market and additional analysis will follow in the analysis chapter.Based on analysis and valuation, the commodities industry has decent valuation as the healthcare industry is undervalued thanks to the high valuation of AZN. The energy industry has low value due to the capital intensive nature of the industry. When it comes to the models and their practical implementation, DCF has been the most problematic to apply empirically whereas RIV was better but it still shows extreme values, which teaches the student the clear difference between theory and empiri..

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.

Driveability analysis of terrain data offers an important technique for decision support for all kinds of movements in the terrain. The work described in this report uses a high resolution digital terrain model generated from the laser radar data and further processed by the Category Viewer program, and information from the Real Estate Map. Properties of features found in a filtering process are calculated and compared with a set of rules in a knowledge base to get a driveability cost. This cost is then visualized in a graphical user interface. An evaluation of what driveability is and what it is affected by is performed, and a general cost function is developed, which can be used even if not all relevant information is available.

AbstractThe purpose of project is to study the possibility for Borås Energy & Environment to build and run a commercial ethanol production facility in Borås. The project also studies the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with focus on two processes, svag-syra hydrolyse and enzymatic hydrolyse. The technology of the process is based of hydrolysation of biomass (hemicelluloses and cellulose) to sugar and extract it to ethanol. These two techniques will compare with each other to determine which of them that it?s more suitable for ethanol production.

The current planning philosophy is based on a political utopic modernism founded during the first part of the 20th century. The focus is, in planning a defined area, to maximize the internal efficiency and to create a competitivesociety. During the latter part of the former century globalization changed the context, thus creating the need for a new way of approaching physical planning. This paper shows that the historical and philosophicalmetaphor of flow can be applied to meet the demands in the global city. It also shows how the edge, as where interaction takes place, is an important part of the content that has to be defined.

In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.

Allt större och större andel företag väljer att presentera och förmedla varor och tjänster via e-handel. En viktig aspekt vid e-handel är att kunden känner förtroende för e-handelsapplikationen och företaget.

The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

The essential thing about breaks has been in relation to time, body, movement, force and room during my examination. Through conversations high-school students from two schools have taken part in this study. The examination is based on conversations with the students and has focused on students? experiences of breaks, and is also carried through by the method of phenomenology. The results of my studie show that students - during their breaks - experience a feeling of allways heading for something and also that time seem to exist in three levels: filled time, non-filled time and flow regarding of time.

Hyperthyroidism has become the most commonly diagnosed endocrine disorder in cats. The recommended treatment of choice in the literature is administration of radioactive iodine. This treatment has been available at a few veterinary clinics in Sweden since 1999. Forty-six cats treated with a standard dose (80 MBq) of radioactive iodine (131I) at the Swedish University of Agricultural Sciences in the period 2000-2004 were followed for a median of 13 months (range 3-42 months) by means of a retrospective cohort study design. Tables predicting time of survival after treatment were made. At final follow-up thirty-nine cats (85%) were euthyroid, six cats (13%) remained hyperthyroid and one cat (2%) was hypothyroid.

Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the utilization of low grade industrial waste heat. The study is based on the foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.
