The energy sector of modern time is currently faced with several challenges. These are both production oriented and environmental oriented in nature. The energy of the future is intended to support an increasing demand while at the same time reduce its environmental affection. This stresses a development towards production methods of renewable energy. Among the existing methods, biogas is presented as an attractive alternative.

This essay is written in order to expose the construction of collective identity in textbooks for Swedish as a second language. To help visualize the process that shapes and categorize sub-jects based on a relational identity formation I assume mostly from Ernesto Laclau and Chan-tal Mouffe's discourse analysis theory frame. The paper called it as discourse theory. There are two textbooks in Swedish as a second language to be studied. Based on the textual materi-al found in the textbooks I perform a discourse analysis involving mainly focus on relational identity construction.

AbstractThis report describes our ten week long thesis work which is the last task in our education in mechanical engineering at Linköpings University. The project has been performed at Siemens Industrial Turbomachinery AB?s service department. The company which is located in Finspång produces, sells and provides service for steam and gas turbines around the world.The purpose of this project is to help Siemens develop their maintenance programs for two of the auxiliary systems which are a part of the complete steam turbine system. These are lube and control oil systems.The project is restricted to two of Siemens maintenance products, No Stop Check (NSC) and the annual Safety Inspection (SI).

How does IT-consultants reason in their consulting process regarding the development of a clients IT-based internal recruitment system? The purpose with this paper is to investigate how an IT-consultant is reasoning in a consulting process and investigate whether consultants are using established models and methods in their work. We have chosen to work with a qualitative examination to attain our purpose. In our work gathering the empirical facts we have been working with a case study, an observation and a simulation exercise. The combination of these has made it possible to carry out the paper and produce the most correct data possible. Conclusion: We state that IT-consultants do not use any theory-based methods, they use process methods created by themselves and their company.

Projects to equip every student and teacher with a laptop, with the intention to improve academic results, have rapidly spread through the country. New technology, new contents and new ways of learning have changed the learning envi-ronment. The school library, being a part of this environ-ment, faces the same changes and challenges.The purpose of this thesis is to study how the school library is being affected when a One-to-One project is carried out in a learning environment. The research questions concern how the school library is viewed within the organization and also how the change affects both the school library and the school librarian.The empirical material of the thesis includes five qualitative interviews carried out on location, at a single selected school. The interviews are followed by a study of relevant documents, all produced within the organization.To understand the organization in which the school library operates, as well as the school library itself, I chose to divide the theoretical approach in two: Christensen?s et al.

So called honour based violence is a present problem in Sweden. Although recently there has been a steadily growing political and academic awareness around so called honour based violence, there are still problems in the face to face meeting with the victims. This dissertation contributes to the understanding of these victims. The empirical material is based on five young women's stories about growing up in a context of 'honour' and their experiences from breaking up from this context.  My ambition is letting these stories be heard and told as to lead to an increasing understanding of how these women experience themselves and their surrounding society. The purpose of this dissertation is to illustrate how young women interpret their self in the light of a separation from their families.

Title: Co-operative, prevent or complement? - An essay on the relationships between control systems. Authors: Kim Eriksson and Victoria KarlssonPurpose: The essay aims to describe the relations between control systems and how they related to each other, based on an operationalization of the control systems. Research question: What are the control systems relations to each other? With regards whether control systems co-operative, prevents and/or complement each other.Theoretical framework: The essays theoretical framework is based on Malmi and Browns (2008) description of five different control systems and control mechanisms associated with each control system.   Research methodology: The method was based on three different data collection methods. These methods were observations, documentation, and semi-structured interviews.Conclusions: It is concluded that the control systems has comprehensive relations. Control systems have more, than one, relation to each other..

The purpose of this thesis is to examine how semantic relations in a document collection can be visualized with a Kohonen self-organizing map. It can be seen as a map of the information space which can be used to support information retrieval. The study makes a comparison of the possible differences between a map that is based on morphologically unprocessed text and a map where the text has been lemmatized. The text that is being processed is the definitions of all the existing instances in WordNet of a random selection of indexing terms from the Times-collection. The purpose is to see if morphological processing somehow can show different semantic connections between term instances based on their definitions.

Musikgenren punk är nu över 30 år gammal. Och syftet med denna uppsats är att se likheter och skillnader mellan ett par tidiga brittiska punklåtar och ett par tidiga svenska punklåtar. Och ta reda på vad som kännetecknade det musikaliska i musikgenren. Frågorna som ställs i uppsatsen är: Vad var det i det musikaliska som kännetecknade musikgenren? Och vilka musikaliska likheter och skillnader hade den tidiga brittiska punken och den tidiga Svenska punken?För att få svar på dessa frågor så har fyra stycken musikaliska verk analyserats: Sex Pistols ?Anarchy in the UK?, The Clash ?White riot?, Ebba Grön ?Ung & sänkt? och P.F.

Hotellbranschen har utvecklats till att fokuserar mer på att locka externa besökare utifrån, vilket förändrar dynamiken kring hur hotell ser på sig själva och dess omgivning. Denna uppsats syftar till att studerar hur hotellen använder sina publika utrymmen såsom lobby, bar och restaurang till att locka mer människor utifrån och vilka typer av rum som skapas. Uppsatsens empiriska material bygger på intervjuer med anställda på olika hotellkedjor i Stockholms län. Det teoretiska ramverket bygger främst på Ray Oldenburgs teori om den tredje platsen men även kring teorier om hotellens påverkan på städer, tjänstesamhällets utbredning och teorin om buzz. Resultatet av studien visar att hotellen har förutsättningar och möjligheter att fungera som mötesplatser som liknar den tredje platsen genom att de fått nya möjligheter genom att kombinera deras tillgång till ytor och ny teknik.

Preschool is an important social arena for children. This might be the first time that children find themselves in a larger social context and create their first peer-relations. The aim of this study was to examine children?s peer-relations with particular focus on the acts of social exclusion and inclusion, and how children use different strategies to exclude and include each other. Another aim was to investigate how both verbal and non-verbal communication is used in these processes.This study has an ethnographic approach, and the use of video observation as a method enabled us to capture the children?s everyday interactions at preschool.Our results show that children use a number of different strategies to exclude other children that seek access to an ongoing activity to protect the interactional space that they already share.

Det bör vara möjligt att skapa verktyg för att beskriva scenarion och med hjälp av tillgänglig mjukvara för visualisering kunna spela upp både verkliga och simulerad bilddata. Detta examensarbete beskriver hur några sådana verktyg tagits fram. Till förfogande fanns en stor mängd bilddata, insamlad på ett militärt övningsområde som dessutom finns representerad som en syntetisk omvärldsmodell. Insamlingen gjordes med en UAV (Unmanned Aerial Vehicle)- prototyp, som var utrustad med videokamera, IR-kamera och tröghetsnavigeringssystem. För att simulerad bilddata skulle få ett verklighetstroget intryck placerades markfordon ut i den syntetiska modellen på exakt samma position som under fältförsöken.

Sveriges Radio stores their data in large archives which makes it hard to retrieve specific information. The sheer size of the archives makes retrieving information about a specific event difficult and causes a big problem. To solve this problem a more consistent use of metadata is needed. This resulted in an investigation about metadata and keyword genera-tion.The appointed task was to automatically generate keywords from transcribed radio shows. This included an investigation of which systems and algorithms that can be used to generate keywords, based on previous works.

The purpose of this study is to investigate the proposed leasing standard's potential effects on stakeholders' financial key ratios and estimated bankruptcy risk via prediction models based on accounting ratios. This is achieved by adjusting the financial statements in accordance with the three most widely used ways of dealing with operating leases at date; capitalizing using a multiple, capitalizing through a present value method and to not adjust for them at all. Since the discounted method is said to reflect the proposed standard the closest, this version will be compared against the two other versions. The research is based on Nordic retail companies due to their high share of leases. The study shows that the unadjusted key ratios and estimated bankruptcy risks tend to be too low and would therefore deteriorate in combination with the new standard, when again the multiple method results in too weak key ratios and high estimated bankruptcy risk and would therefore tend to improve in combination with the new standard.

This report is about finding the cooperative elements in games and making a boardgame based on them. I tested different computer games and boardgames to try and get the cooperative elements and then I make a boardgame based on what I found.What I found during testing is that to be a fully cooperative game all players on the same team must win or lose together and one player should not be able to finish the game by herself. There are of course some things that can change this for example what kind of players are playing.My best advice is that you should decide that the game is fully cooperative from the beginning and build the game from that..
