The aim of this Master's thesis is to understand public library users' perceptions of librarians' attitudes to users and professional knowledge. The purpose was also to investigate the relative importance to the user of pleasant or a knowledgeable librarian. As a theoretical framework we use theory from business economy where the experience of the user is in focus. Answers were sought to the following questions: How do users perceive librarians attitudes to users? How do users perceive librarians professional knowledge? How do users want to be treated by public librarians? What kind of knowledge should public librarians have, according to users? We interviewed twelve students in university education that are users of public libraries.

Purpose/Aim: This essay explores the framing and representation of pensioners in Swedish press during the period of 2002-2008. The aim was to investigate what meaning news give elderly people on the manifest level, and also what meaning the media texts construct on the latent level.Material/Method: For this paper I have investigated framing of pensioners using quantitative analysis of 100 news articles, followed by a qualitative hermeneutic analysis applied on the most frequent frames discovered in the quantitative study.Main results: Four frames were identified concerning pensioners: crime victims, heroes in daily dues, economically advantaged and economically disadvantaged. The dualistic result in the economy frame was investigated in the qualitative research. The study revealed that pensioners as a group may have good economic standards, although there are individual differences. Three stereotypes were discovered in the articles: ?kind granny?, ?fragile and miserable? and ?look what I can do?..

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

The aim with this paper is to study Karl Popper?s view on realism and relativism. Further aim is to see whether those ideas have been consistent over the years. The paper argues that Popper since his first interest in philosophy has taken a realistic and antirelativistic attitude. Only his arguments for this position have been developed to meet his critics.Common sense speaks for realism but can neither be proven nor refuted.

In this study we examine how much latency is required in an RTS-game (Real-Time Strategy) before the player quits the game. In the study latency is simulated in the games Age of Mythology and Starcraft: Brood War with the program WANem, and then the testplayers are asked ?Do you want to quit because of latency??. This data is then gathered and compiled into graphs to show the results. These results show that the limit for when players want to quit differs between the two games and that there are two factors that play into this.

The main purpose of this thesis has been to identify and discuss problems connected with the preservation of newspapers in Sweden. Another purpose was to see if the preservation of newspapers has been influenced by the fact that preservation studies in general concerns printed monographs and digital materials. This qualitative study is partly based upon interviews with four librarians experienced in working with newspapers and preservation. The thesis deals with cultural heritage in general and on a more specific level with newspapers where the following questions are dealt with: Why preserve? Who preserves? How to preserve? and What is preserved? Strategies used for preserving newspapers such as paper, microfilming and digitization are described as well as legal deposit, the Swedish microfilming programme and TIDEN, a digitization project of newspapers.

The purpose of this report is to collect, compile and complement the scientific and experience based knowledge concerning high pressure fire fighting today. The goal is to produce a decision data for the Rescue Service concerning the use of high pressure systems for fire fighting. Focus is on hose reel high pressure systems but other systems are discussed too. The report begins by describing the technical properties of the different systems. Then the fire fighting properties are evaluated, including manoeuvrability and safety for users.

The municipality of Olofström is intensifying the co-operation with Sölvesborg and Karlshamn, the two other municipalities in the west of Blekinge. They co-operate in two local federations and for the moment negotiations are going on about a third local federation in continuation school, but the municipalities do not agree. The aim of this thesis is to examine why Olofström co-operate with Sölvesborg and Karlshamn, if there are any problems and where the limit of this co-operation is. The method in the thesis is qualitative interviews with local politicians and officials and an actor-structure-perspective is used. The result shows that Olofström is a municipality where the population is decreasing, and it has lost state subsidy during the last decade.

The forest is characterized by many different values such as those related to forest productivity which are of a big importance for Swedish economy. History has proved that forest resources had helped the country in the transition from the agricultural to the industrial society. Today Swedish forest industry is among the strongest in Europe and significantly contributing to the Swedish export. The industry provides many direct and indirect job opportunities and is one of the biggest employers in the industry sector. It is also worth to notice that the forest can also generate an additional income for the owners, even if the forestry isn?t their primary income source.

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

As trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the mass of a heavy duty vehicle in real time has been a difficult challenge for the truck manufacturers. With the processing power for electronic control units in trucks steadily increasing, more advanced algorithms for calculating the mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..

The society of spreading useful knowledge started to sell its magazine Reading for the People (RFP) in 1834. The idea with the society was to, through the magazine that contained useful knowledge, enlighten the Swedish peasantry. RFP contained articles about agricultural and economy for example.My goal with this essay is to investigate how the use of foreign articles in RFP changed over time. I?m also going to present a field and language categorization of the foreign articles and study the articles from Benjamin Franklin and Charles Dickens and investigate what kind of articles they wrote.

Syftet med denna studie är att beskriva och analysera sju kommuners soliditetsutveckling under 2006 till 2010 samt analysera om ett samband finns mellan låg soliditet och genuin sårbarhet. I uppsatsen används en blandning av kvantitativ och kvalitativ metod för att få en djupare förståelse kring kommuners soliditet och dess soliditetsutveckling. Insamlad sekundärdata kommer från böcker, artiklar, uppsatser och lagar. Primärdata samlades in vid en intervju samt genom sju kommuners årsredovisningar.Ett lågt antal invånare i en kommun behöver inte resultera i en låg soliditet. En befolkningsminskning behöver inte leda till en minskad soliditet.

The study was a quantitative cross-sectional study which aimed at investigating college students? eating habits in relation to the Swedish food agency dietary recommendations. The likely factors associated with eating habits and attitudes towards dietary recommendations were also investigated. Non probability sampling method was used giving rise to convinient study sample of 51 individuals (41 women and 11 men) ages 19 to 37. The participants were part of four different types of educations, Care and health, Economy, Engineering, computering and societal planning and Culture and media.
