The purpose of this study is to establish whether or not there is a connection between a highincidence of computer gaming and English proficiency in Swedish 9th-graders. The study also takescomputer game genres into account, attempting to see if there is a link between frequent playing ofcertain genres and high English grades.According to this study, there is a clear correlation between the gaming habits of Swedish 9thgradersand the grades they receive in English, with a higher frequency of gaming corresponding toa higher grade. The study also suggests that the Strategy, MMO (Massively Multiplayer Online) andCRPG (Computer Role-Playing Game) genres have a higher representation amongst students withgood grades in English..

This Master?s Thesis deals with a special problem that may be of importance when planning a frequency hopping mobile communication network. In normal cases the Frequency Assignment Problem is solved, in order to plan the use of frequencies in a network. The special case discussed in this thesis occurs when the network operator requires that the frequencies must be arranged into groups. In this case the Frequency Assignment Problem must be solved with respect to the groups, i.e.

The purpose of this Masters thesis is to compare classification codes and feature headings of three different universal classification schemes SAB, UDC and DDC, when classifying archaeological literature. The aim is to determine whether a subject analysis of a title generates similar feature headings in the three systems, and to find positive and negative things about each system from an archaeological point of view. The comparison and the analysis of the 22 chosen archaeological monographs showed that the subject analysis of the titles didnt always generate similar feature headings. This could depend on several things, for example different interpretations of the subject analysis of a document, less knowledge about the system and/or the subject, or the fact that its not the same classifier that creates the codes. The study also showed that the different classification systems did treat the subject archaeology a bit differently, and that its difficult to say that one of them is better for classifying archaeological literature.

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..

Today's high oil prices and more stringent environmental requirements have led to that manufacturers of mobile construction equipment try to make their products more energy efficient. With this in mind a project about hybridization of hydraulic systems has been formed. The purpose of this project was to analyze the savings that can be achieved by hybridization of hydraulic systems. A reach stacker truck (Kalmar DRD450-80S4XS) were simulated in some load cases with conventional hydraulic systems and with three types of hybridized hydraulic systems. Different parts of the hydraulic systems were also analyzed separately.

There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

Open source is growing outside the boundaries of hackers, amateurs and software development, creating a humongous potential in many different areas and aspects of society. The intrinsic and extrinsic motivations that drives open source have been in the subject of much research recently, but how they affect each other when paid and unpaid contributors come together is still hidden in obscurity. In this study I investigate how intrinsic and extrinsic motivation correlates with each other and how those correlations affect paid and unpaid open source software contributors. The literature synthesis is based on of systematic reviews through searches in library databases, identification of articles by searching on the Internet and by reading relevant books. My results indicate that intrinsic and extrinsic motivations continuously affect each other and that paid contributors are more vulnerable since their extrinsic motivation in terms of money is reached only when many other motivations are fulfilled.

The aim of this thesis is to mediate to the reader an image of Chinese classification systems and in what way the methods of classification have progressed during time. The tradition of classification in China is very old and dates back more than two thousand years, but it wasnt until the downfall of the dynastic era in the beginning of the 20th century, that Chinese libraries and methods of classification were modernized. This thesis also identifies the development of Chinese librarianship which is of old age since Chinese literature stretches three thousand years back. The main question is in what way the values of three different philosophies are reflected in five classification systems compiled between 1953-1975. The three philosophies are Daoism, Confucianism and Maoism/Mao Zedong Thought.

The aim of this thesis is to describe and evaluate the usability of two Swedish systems, Sofie and Carlotta, which are used to organize and present data regarding museum objects on the web. This thesis also presents how objects are described and made accessible to the public in the two systems. To evaluate the usability, a heuristic method combined with Systematic Usability Evaluation has been used. The description and accessibility of object representations in the systems are evaluated using indexing and classification theories from the field of Library and Information Science. Additional theoretical background that has been used is how users search and browse information systems.

Today there is a shortage of skilled IT-technicians in Sweden. It is approximated that Swedish companies can hire 31 000 IT-technicians in 2015 and the need seems to increase in the coming years. One proposed solution to this problem is to make programming more desirable to youths. In this study we attempt to investigate the effects of an introductory course in computer science on youths? (16-17 years old) in a classroom setting.

Vårt mål är att förhöja deltagarnas upplevelse i levande rollspel (även kallat lajv). Idag finns det inga möjligheter att visualisera övernaturliga förmågor. I den här rapporten visar vi ett exempel på hur detta kan realiseras med hjälp av teknik. Vi har inriktat oss på att simulera alvers övernaturliga hörsel. Levande rollspel är mycket känsligt för störningar från ?världen utanför?, exempelvis modern teknik och språk.

In health care today at Uppsala County Council the daily work involves spending time at the computer. IT-systems were implemented to support and aid the care givers in their work. Around these systems there is a support organization to support the users in using the system. The aim of this thesis is to investigate this organization in terms of how well it works and how successful it is in helping the users. This has been done by investigating the flow of information trough the organization and by focusing at the role of IT-coordinators with responsibility for support, process development, education and statistics.

This thesis deals with classification of the subject field history of medicine. The two classification systems SAB and NLM are compared in order to find out which one is the most adequate to organize a small collection of history of medicine. SAB and NLM are the two most commonly used classification systems in medical libraries in Sweden today. NLM classification system specializes in medicine and SAB is a universal classification system. Our purpose with this study is to find out the pros and cons of each system, whether the systems treat the subject history of medicine in a satisfactory way and what kind of classification system that is better for this assignment, a specific one or a general one.

Usability studies are not a central field of research in library and information science. Although literature in library and information science treats the importance of usable user interfaces quite extensively, the literature does not significantly treat potential problems in measuring usability. The aim of this master thesis is to investigate, through a critical analysis, the methods used when conducting usability studies in library and information science. The critical analysis is based on potential problems in measuring usability identified through a literature review from the field of studies Human-Computer Interaction, the concept of usabilitys original domain. The material which is to be analysed, is chosen from one library and information science journal Journal of the American Society for Information Science and Technology.
