Laser for material processing possesses a number of advantages which mean that it has been and will be an important component for a wide range of industries' future development. Cutting materials processing is the dominant use of laser technology and has revolutionized the manufacturing industry. The aim of this thesis is to describe the principles of metal cutting by laser, how laser cutting is applied in practice and to identify how Swedish companies are using laser cutting. For the theoretical and technical description of laser cutting literature studies are the primary source of information. The empirical basis for the mapping of the Swedish industry for laser cutting is grounded on a survey; this includes Swedish companies that use laser cutting in their production.

Banverket Trafik has a responsibility to make sure that the companies who traffic the Swedish railroad have the correct information about the status of the railroad. One of Banverket Trafiks information systems (Opera) presents the train?s actual position on a map and provides the user with physical information about the trains. Due to increasing demands on the information systems, Banverket Trafik needs to update the present system architecture in order to manage the increasing demands on map graphics and map functions. This paper analysis the information system Opera on the basis of theory and support of methods and discuss problems and demands for Opera.

How can the relationship between serious leisure and information activities be described?The theoretical framework consists of the sociologist Robert A Stebbins? theory about serious leisure. The study is based on a qualitative methodology.

The aim of this Master?s thesis is to study the information needs of the homeless. The main focus is to investigate what kind of information needs that are to be found among the homeless and also how information is exchanged and shared by the group. Another aspect of our study includes the sources that are used to fulfil these information needs. The homeless use of the library, as one of these sources, is also examined.

This study focuses on trying to understand the attitudes of people born in the 1940?s concerning their view on social media. This 1940?s group has been growing on the social networks such as Facebook, but their usage is not active. Therefore, the purpose of this report is to understand in what way they are affected by the using of these platforms.

Question:"Does the market possess perfect information as the efficient market hypothesis says?""Is there any significant relationship between the abnormal stock return on the ex ? day and the dividend?" Purpose: The purpose of this study is to enlighten and find understanding about stock return versus dividend on the ex ? day and try to figure out if abnormal returns occur on the portfolio during dividends.Methodology:The study was based in a quantitative nature and was derived with an event study and a hypothesis testing. The authors investigated the thirty most traded shares on the Stockholm stock exchange during a period of five years (2005 ? 2009). They were analyzed during a total of nine days; the estimation window was set to sixty days.

The ordinary phone of today is not the same as it was 10 years ago. We still use them tomake phone calls and to send text messages, but the ordinary phone of today has muchmore uses, it is essentially a computer. To put into context to 10 years ago, it is a verypowerful computer, capable of processing wide array of information and presenting it tothe user. Nearly every single device today has a wireless connection, which makes everyuser connectable and able to use online services and internet at any time and place.This gives the user the possibility to integrate his or hers everyday actions with socialmedia and different search functions. Being able to search the internet for persons,restaurants, public transportation and a lot more is very useful to most.

Adolescence is a turbulent time in life and gives rise to new information needs for young people. Information needs related to school subjects have been relatively well researched but few studies have focused on information needs and use related to life concerns. The purpose of this Master's thesis is to examine the information needs of a number of teenage girls in relation to their life concerns and how they meet these needs. The sample consists of twenty-one girls aged thirteen and fourteen. The research is based on literature studies and qualitative interviews combined with a questionnaire.

This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.

In this study, I have examined the previous Social Democratic government?s communication with the voters, focusing on its promises during election campaigns, and the presentation of achieved results. The theories used are the mandate- and sanction theory; the first focuses on voters comparing manifestos to find the most agreeable, whilst the latter concentrates on voters evaluation the work of the previous government, to either discharge or support it. For the sanction theory to work, voters must have the necessary information to evaluate the government in progress. The question is; did the previous government provide the voters with such information?This has been done through scrutinizing the Social Democrats? election manifestos that was used between 1994 and 2006, to examine what the party promised to achieve in economics and the labor market.

The aim of this Masters thesis is to describe the information behaviour of six adults with dyslexia with focus on how they handle information problems. The data consists of literature and interviews with six persons with dyslexia. The theoretical framework used in this study is Anders Hektors theory about human information behaviour as well as concepts and theories from the library and information science field. Ten information activities are used to describe the informants information behaviour. Answers are sought to the following questions: · How do the informants describe their backgrounds and their reading- and writing disabilities? · What problems do the informants meet in the context of information in their everyday lives with reference to ten particular information activities? · How do the informants solve these problems? The study showed that the main problems for the informants appeared to be difficulties with reading and spelling, problems with the appearance of the information, lack of time and stress while reading and writing as well as problems with lack of awareness about dyslexia.

The aim of this master thesis was to examine the European Commission's information resources from a user perspective in order to clarify the needs and circumstances of the search of EU-information among students at Örebro University. 41 students participated in a survey, and four of them was interviewed. On the basis of Pendelton- and Chatmans theories of information behaviour in small worlds, it were assumed that the students' education and citizenship in the European Union affected their needs and the search of EU information.The study showed that the students needs for EU-related information has increased, with the current education, but also been linked to earlier educations. The students Citizens need were mainly associated with elections such as the EMU-election, but also in some cases to a need of the general knowledge.A review of the European Commission's information resources were made with an emphasis on European Documentation Centre, EDC. The survey showed that most students used the EDC and the EU-databases that was made available by the European Commission through the EDC and the university library but were not aware that they used EDC.The survey also showed that students made use of familiar sources and resources when they searched the EU-information, such as the library's regular database list, the library catalogue and search engine on the internet are not requested of other resources.

The purpose of this essay is to examine how girls groups, particularly in school, can help girls with feelings of stress and pressure they can experience in their everyday life. We also want to examine how girls groups can be used, and explain why they should be held in school and not only in other organizations. The information we?ve gathered comes from books and websites that cover the subject. In addition to this, we?ve also handed out surveys and implemented interviews with both younger girls with girls groups experience, a teacher and a youth recreation leader. The theoretical aspect of this essay stems from two different theories: Labeling theory and Strain theory.
