This thesis examines the ongoing European political debate on the links between livestock production and climate change. In the end of 2006 the UN Food and Agriculture Organization (FAO) released their report Livestock?s long shadow, showing that livestock production represents some 18 % of the total global greenhouse gas emissions. The purpose of this paper is to explore the European Commission?s position and response to this question since the release of the report.Using Arne Naess? argumentation analysis, statements made by the Commission will be systematically organized and broken apart.

The goal of this Master thesis has on the one hand been to create a simulation environment for robots, where not only the simulations in this work can be performed, but also similar robot simulations, and on the other hand to study regulators that can increase the possibilities of rejecting disturbances on an industrial robot. The robot model used has three degrees of freedom, corresponding to the three main links on ABB:s IRB7600. The simulation environment is created using Matlab, Simulink, and Robotics Toolbox. It is constructed in a general way and can be used for simulations of other robot objects created in Robotics Toolbox. A gain scheduling is added to the LQ-regulator, where the feedback matrix is varied depending on the arm position in the workspace.

The aim of this thesis is to study how the recent introduction of video games in Swedish public libraries compares to past introductions of other medias, namely music records, sequential art, manga (Japanese comics), and films on video. In what ways does the introduction of video games differ from the other examples of introductions and in what ways are they alike? In what manner have the medias been introduced? How does the librarians views on video games differ from their views on other medias? The purpose of doing this is that by investigating how new medias have been evaluated in the past, we might gain an understanding of how the introduction of video games links into that tradition. Theoretically, this thesis is grounded in Sanna Talja?s theory of the interpretative repertoires of the music library.

This thesis aims at examining to what extent a few, algorithmically very easily extractable document features can be used to classify electronic documents according to genre. A set of experiments is therefore carried out, using only 11 such simple features in an attempt to classify 84 documents belonging to electronic academic journals into three manually identified genres: table of contents, article, and review. The 11 features are also divided into three sets, containing metrics of words and sentences; punctuation marks; and URL links, respectively. The performance when using these sets of features is then measured with regard to classification accuracy, using a k-NN classifier, four different values of k (1, 3, 5, 7), and both leave-one-out and 10-fold cross-validation. Best results are achieved when using all three feature sets (i.e.

The purpose of this paper is to examine whether, and if so, how tourism effect the construction of a new city district with a stadium in focus. The study is based on a case study of Swedbank Arena and Arenastaden as nearby area. There has been an interest from the writers to study Swedbank Arena and Arenastaden, as it is a current subject, and both of them are under construction, which means that it was possible to see how the process works from the ground up. It has been shown that Swedbank Arena is built up in an entirely new district in which there will be new infrastructure that is tailored to the stadium and the crowd it?s expected to attract.

This thesis describes and examines a new line of business, CleanTech. CleanTech comprises a wide range of different types of companies and is not yet well defined. In this thesis only the Swedish market is considered, and a variety of players on the market are included to give the most extensive picture of the current situation. Recent research shows that a gap has arisen between governmental financing and private equity-investments in CleanTech-companies. This gap occurs mainly in companies in expansive phases and causes problems both for the companies and for the line of business as a whole. To investigate this gap the Swedish CleanTech-business is described in terms of earlier and existing financing, age and size of the companies and their turnover and profit.

?Facebook has become as natural as having a phone? The use of social media in three libraries in the Umeå region ? an evaluationSocial media has come to be an integral part of people?s everyday life, as well as the business world in terms of communication and marketing. More and more libraries also embark in the use of social media, and the purpose of this study is to evaluate the use of social media in three libraries in the Umeå region. The libraries all use Facebook as their current, primary social media. Thus this study focuses partly on the analysis of the content on each library?s Facebook page, and partly on the experiences of the responsible librarians. The evaluation is based on a mix of existing tools in evaluating social media that are relevant in a library context.

This thesis evaluates and compares the retrieval effectiveness of the two search engines Google Scholar and Scirus, which both specialises in indexing scholarly material on the web as well as journal articles. Thirty search queries are used and the first twenty retrieved documents for each query are examined for topical relevance and scholarly content. The search queries are based on legitimate information needs taken from a scientific questionbox on the web. Queries are expressed with advanced search operators and are the same for both search engines. Precise relevance criteria are set up and a binary scale is used when judging.

This thesis approaches the problem of estimating the arm angles of an industrial robot with flexibilities in joints and links. Due to cost-cutting efforts in the industrial robots industry, weaker components and more cost-effective structures have been introduced which in turn has led to problems with flexibilities, nonlinearities and friction. In order to handle these challenging dynamic problems and achieve high accuracy this study introduces state observers to estimate the tool position.The observers use measurements of the motor angles and an accelerometer and the different evaluated observers are based on an Extended Kalman Filter and a deterministic variant. They have been evaluated in experiments on an industrial robot with two degrees of freedom. The experimental verification shows that the state estimates can be highly accurate for medium frequency motions, ranging from 3-30Hz.

African swine fever, ASF, was first described 1921, in Kenya. The virus has thereafter spread through many African countries as well as in Europe, Asia, South- and Central America. The virus is spread via three different cycles, of which one is sylvatic and includes warthogs and soft ticks. The other two are between domestic pigs and the one most common one is caused by humans, who not always realize the seriousness of precautions. The infection manifests as hemorrhagic fever, but can also be more or less unnoticed. The aim of this study was to use molecular tools to detect and partly genetically characterize ASFV both in soft ticks and in serum from domestic pigs in Uganda. Comparing viruses detected in ticks with those detected in domestic pigs I also wanted to investigate possible links between the sylvatic and domestic cycle.

The relational database model was defined in the 1970?s and is the dominating database type today.  The main difference between data from a relational database and a hierarchical data structure is that the relational database stores records in tables. The records have no particular order, but can include links in terms of relationships with other records. A hierarchical structure organizes data in the form of a tree structure  and  can for an example be found in organizational structures in which different levels involves different responsibilities. If the data stored in a relational database is to be presented in a hierarchically, a conversion of the data structure is required. The intention of this paper is to describe how such a conversion can be performed.  To investigate the conversion methods, case studies has been conducted on the basis of a specific organization?s hierarchical structure.

In the Real Estate market there are a large number of commercial properties with offices. As acompany or business you are faced with many decisions when choosing your office space.This bachelor thesis examines the concept of architectural quality with focus on beauty and itsvalue for office tenants. The ambition is to find out if beauty is a decisive factor in theselection of office and if there is a willingness to pay for it.The selected question is studied in a case study of Garnisonen where tenants, a propertyowner and an architect are interviewed, all with connection to the examination object.Garnisonen is well suited as a case study because it is Stockholm's largest office complexwith buildings from three different architectural eras. Tenants in the survey represent allarchitectural styles and have different industry affiliation.As a theoretical framework a literature study is presented where the importance of beauty forthe individual, the built environment and society are treated, and also how the office can beused for branding purposes. The interviewees? views of beauty and their opinions on beauty atwork in Garnisonen are presented in the results.

The purpose of this thesis is to examine the performance of different types of queries in the AltaVista query-based search engine. Thirty information needs have been collected from an ask-a-question service on the World Wide Web, which means that they are based on real users information needs. This is done to avoid partiality in the study. The author has invented different types of queries for each and every one of the information needs in accordance with the search syntax available for AltaVista. The types used are Boolean expressions, queries including proximity operators, phrases and queries directed towards a specific field.

The purpose of this master thesis was to study the water system for mechanically cleaned water at Skärblacka mill, in order to find and evaluate possibilities of using energy more efficiently. The thesis also includes an evaluation of the software tool ?Pumpanalys?Skärblacka mill produces pulp and paper. The large amount of water required is cleaned mechanically through filters and called mechanically cleaned water (MR0). The MR0 water is pumped out to the factory by four crude water pumps.

Previous research has established coaches' important role in developing elite athletes (Durand, Bush, Thomson & Salmela 1996). Athlete enhancement and assisting athletes achieve ?peak performance? has been a major objective for elite coaches as well as sports scientists (Williams & Kendall, 2007) Despite this common goal, research also question whether sports scientists and the research they pursue really effects coaches knowledge and constitute a foundation for today and tomorrows athletic performances (Bishop 2008).  This study examined elite coaches? needs and use of sport science research as well as the interaction between elite coaches and sport scientists. Following interviews of ten elite coaches, content analysis revealed that sport science is both a formal and informal resource of knowledge for coaches. Development of athletes is seen as the main objective of research retrieval and personal and/or direct contact with the sport scientist is considered to be the best way to assemble.
