The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

AbstractTitle: The war in Afghanistan ? a necessary evil? (Kriget i Afghanistan ? ett nödvändigt ont? En kritisk diskursanalys av New York Times ställningstagande till och framing av kriget i Afghanistan)Number of pages: 41 (41 including enclosures)Authors: Jenny Häggmark, Madeleine JanssonTutor: Christian ChristensenCourse: Media and Communication Studies CPeriod: Fall term 2011University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/aim: Our main goal with this paper is to examine and describe how The New York Times have framed the war in Afghanistan in their editorials, and how their position on the war is reflected in the editorials. We are also interested in finding out if their position on the war has changed during the ten years of war. Are the New York Times editorials characterized by peace or war journalism?Material/Method: To fulfill our aim with this paper we are going to use a qualitative method of content analyzes, the critical discourse analysis, when we analyze the editorials selected.

This essay deals with a picture-stone that was found in a pre Christian grave during the archaeological excavations of the Viking Age harbour and trading place at Fröjel parish, Gotland, in 1999. The stone is at least 100 years older then the male grave in which it was found. The picture-stone can be dated to  late 8th century or early 9th century, and the grave is probably from the late 10th century. One of the main questions in this essay is why the people of that time re-used an older picture-stone in a younger burial. I believe that the stone was reused as a grave-gift.

This thesis is a qualitative study of a new law that was applied in December 2010. The law is called Lagen om etableringsinsatser fo?r vissa nyanla?nda invandrare, and is meant to help newly arrived immigrants that come to Sweden to establish themselves in the Swedish society. The aim of the study is to see what discourses the Swedish government produces as a result of this new law. Interesting for the study is to see what happens in the implementation stage at a local level, in this case in the municipality of O?rnsko?ldsvik.Theoretically and methodologically I emanate from critical discourse theory and institutional theory.

The actual project presents the development of a testing rig for a steam engine. A short overviewabout the development of steam engines is presented, until arriving to the development of thepresent engine, which will require to be tested in different ways.The testing rig studied on this project (based on a Lanchester engine) will be used to testdifferent materials and layouts for the group Piston-Cylinder.The engine is a high performance steam power engine, which is going to have a highpower/dimensions ratio, what will lead to require high performance components and materials.An introduction to the testing rig is presented, and the entire design project is done in order toreplace the disappeared documentation of the current testing rig, built on the 1970?s. Also somemodifications done in the original testing rig are presented, as well as some detected problemsand their possible solutions..

Vi har valt att göra vår C-uppsats i relation till en begränsad verksamhet; en fritidsverksamhet i Västra Götalandsregionen. Vårt syfte med studien är att undersöka hur pedagogerna gör kön i interaktion med barnen, i de observerade situationerna. Våra frågeställningar är ?Vilka samband kan vi se i observationerna mellan pedagogernas interagerande med barnen och barnens positionering och kön?? och ?Hur svarar barnen på pedagogernas interagerande i förhållande till barnets kön och intagen position??. Vi har använt oss av videoobservationer som metod och filmat samlingar och mellanmål, då vi var intresserade av att studera pedagogernas interagerande med barnen utifrån barnens intagna positioner och kön.

Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.

The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.

Today equal representation between the genders in parliament is something to be desired. One way to reach the goal of equal representation is by using quotas. The purpose of the study is to research the lack of equality in elected institutions by using a perspective on qoutas.  The study also seeks to find answers to if using quotas is a good method according to gender studies. A text analysis is being used to find reasonable solutions to the study´s presented complivations.  By analyzing different texts about quotas some of the more common arguments in the discussion about using quotas in parliaments were highlighted. Some of the more frequent arguments to implement quotas are that it would be more just but also that women and men may have different interests, experiences and therefore equal representation would be a question of resources.

The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.

AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.

Wireless communication is becoming more common, a relatively new technology within the area is Bluetooth Low Energy. It?s been developed to be energy efficient and in regard to compatibility. Alongside the growth of wireless technology, scientists and companies are looking for new areas of use. One of these is localization, which means to determine the position of a moving device with the use of stationary devices, an example of this would be GPS.This report means to evaluate indoor localization using Bluetooth Low Energy and was made for Combitech AB in Jönköping.
