In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.

Journalists and communication managers are becoming more professional and to reach out to its stakeholders in society today, organizations must work strategically with communication, to enter the news.

This study investigates the use of the social network Facebook among 67 Swedish libraries; 27 academic libraries and 40 public libraries. Data is collected through an analysis of the libraries? Facebook pages and through an email survey. To analyze the data, a series of statistical analyses were performed.The results indicate that the public libraries more actively posted Facebook updates than the academic libraries and that the libraries that had a policy for use of Facebook/social media more actively posted updates than those libraries that did not have such policy. The libraries use Facebook mainly to post links and photos and to announce events, provide book recommendations, and to emphasize special occasions.

The aim of this master ´s thesis is to understand why there are difficulties in finding joint methods and standards in the field of image indexing. The main focus for interpreting these issues is on Sara Shatford ´s article Analyzing the Subject of a Picture: A Theoretical Approach. In the article Shatford discusses a theoretical basis for identifying and classifying the subject in a picture. In doing so she uses concepts taken from The Philosophy of Art, Meaning in Language and Visual Perception. With the aid of S.R.

The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.

The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

This Masters thesis is concerned with the complex planning process of setting up a citizen bureau in a public library. The aim is to find out how citizen bureaux are designed and to suggest a simplified model of strategic planning. The planning process is studied from a business perspective in the library context, and this perspective is also used to study citizen bureaux and their written plans elsewhere. A combination of qualitative methods are used: observations, focus group discussions and interviews. Observations in the public library showed a great need for an environmental analysis as well as structure to the planning process.

The following theories has been used to reach the objective: the journalism task, news values, the liberty of press and speach, media ethical rules and discursive discrimination. The study has used a critical discourse method formed by Teun a. van Dijk to analyse the material, mainly through macro- and microstructures.

 Performance appraisals- a study of the performance appraisals significance as a tool for development in the public sector.Anders Larsson and Åsalill OlssonPerformance appraisals have been given a central role in leading businesses in the public sector and are seen as a tool to create development opportunities and achieve better results. This has resulted that performance appraisal in many organizations takes up capacity and time. This was the starting point of our interest to study whether the time spent on performance appraisals effectively pays for itself in the organization, in other words whether the effects expected actually are achieved. The paper examines first line managers` views on staff appraisal purposes and effects of a function within the Landstinget. The survey design, methodology and transaction are of qualitative and quantitative method with three different sources: literature review of previous research, interviews with first line managers in Landstinget Västmanland and the results from an employee satisfaction survey conducted on behalf of Landstinget Västmanland.
