This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.

The project was intended to produce a brush simulation plugin to the image processing program GIMP which would use a 6DOF drawing tablet for user input.Too ambitious goals coupled with compability issues between the resources used resulted in that no meaningful software was produced. Experience was however obtained, and this paper is intended to give an overview of relevant concepts for- and the process ofcreating a brush simulation..

The tick-borne disease bovine anaplasmosis is primarily caused by Anaplasma marginale. A variety of wild animals act as reservoirs for A. marginale, but the understanding of their role in the epidemiology of A. marginale is yet poor. This cross-sectional study was conducted to establish if proximity of wildlife affect the prevalence of bovine anaplasmosis in cattle.

This is the end report of my final exam at Medieteknik. It covers the planning, work process and review of a Flash based web application that I set out to do. The goal was to create a user friendly, interactive e-shop with embedded functionality for playing music, displaying rich media content and researching possible payment solutions, to enable buying music files online. The project involved creating the user interface, the programmatic functionality of a Flash client (an SWF file). Also, setting up an Apache HTTP Server and establishing a working ?bridge? between the Flash client and the web server with Flash Remoting components and AMFPHP.

This thesis was made possible by the company Verendus system AB, which is the leading developer of dealership management systems in the caravan and camper market. The goal of the thesis was to create a statistics module for a new producer system envisioned by Verendus. The new system is aimed at manufacturers and importers of caravans and campers, with the goal of enabling its users to create more effective production lines. By providing statistical data to mentioned users they will be able to predict market trends and customize their production lines accordingly. Today such software does not exist which leads Verendus to think that its arrival would lead to a success on the market.Before the development and design of the producer system began, a new agile method had to be developed, MAM (Minimum Agile Method).

This Master thesis focuses on change conditions and change ambitions in Swedish public libraries. I have chosen to focus on three libraries that participated in a much-debated developmental project sponsored by the Swedish Arts Council almost twenty years ago. The aim of the project was to enhance service-quality, increase user-influence over media acquisition and library routines, and to redefine the concept of quality in the library context. I have made comparisons of the conditions and change ambitions between the project period 1991-1994 and present day 2009. To do this I have analyzed the evaluations of the above-mentioned project and the developmental plans that every municipality in Sweden is required to write according the library-law of 2004.

Litorapid Media AB is a printer and prepresscompany, located on Hisingen, Gothenburg. Litorapid is a relatively large company, and is therefore in great need of convenient contacts with becoming and present customers. Seeing that they work with the most rescent technique in the branch of printing, it is important that they market themselves in a modern way. The purpose with this project became, for that reason, to create a more contemporary home page for the company to catch new customers, as well as aninteractive presentation of the company to create a more personal contact with customers they alreay have. The home page was created in the programme Macromedia Dreamweaver 4, and its design is based on previouly distributed brochures.

Globally, coastal ecosystems like mangrove forests, sea grass meadows and salt marshes are well known for their ability to capture and store atmospheric carbon effectively. In Sweden, there is still limited knowledge about local coastal ecosystems with similar functions, with alder swamp forests being an interesting example. Therefore, this study aimed to increase knowledge of the factors that can contribute to the potential carbon sequestering ability of alder swamps. Vegetation data and sediment samples were collected from a total of 37 sampling plots across four alder swamps in Bohusl?n on the Swedish west coast.

This thesis deals with an iterative user-centered IT-development project in a bank setting. The aim is to present a solution for deployment of future Internet banking for small businesses. The project features a design of IT-related concepts and ideas with a strong emphasis on scenario-based design and the usage of patterns as a documentation tool.The project plan featured an iterative framework and was carried out by a group of designers in collaboration with a reference group representing the future users of the system. This group consisted of company managers and bank employees, all from the small town of Åtvidaberg in Sweden.The method used in the development process was Scrum. A total of three sprints were completed with user meetings at the end of every sprint.

A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.

Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.

The purpose of this master?s thesis is to investigate how librarians approach to the multicultural collection development and which methods they use in providing library materials in minority languages. The questions to be answered are: which methods the libraries use when purchasing library materials in minority languages, how the respondents experience that the minority user groups needs are met in the library and how the multicultural competence of the staff is used in the libraries. For this purpose the qualitative interviews with 6 librarians in Gothenburg are conducted, mainly from the libraries in the immigrant-dense parts of the city, while the study being concentrated on 6 language groups of library users. The study?s theoretical framework is based on theories of multiculturalism, culture, identity and bilingualism.

Most of the city of Uppsala rests on postglacial clay with a varying content of sulphur. The sulphur occurs naturally in the clay in reduced form as sulphide and the clay is for that reason usually called ?sulphide clay?. Excavation during construction activities gives rise to large amounts of excavation material, of which the sulphide clay is a considerable part.When the clay is exposed to air and water, an oxidation of the sulphides occurs which may produce an acid leachate and the mobilisation of heavy metals bound in the clay or underlying material. The aim of the work has been to improve our understanding of the behaviour of sulphide clays and produce a basis for risk assessment in the future handling of excavation material with high sulphide content.

The thesis is about exploring possibilities for developing a standardised system solution for micro businesses, this since most of the micro business lack proper system solutions, a contributing factor of this is price and also incompatibility between the solution and the business itself. The system solutions we will refer to are solutions which task is to cover the most important needs that a micro business might have on their system. The main goal with this research is to see if this is possible, and if so, how the developers should think to take it further. We chose to do this by identifying the most significant of needs a micro business has when it comes to this type of system solution.In this thesis we will present three needs which were evaluated and brought forth through the analyses of various interviews and observations we had done during the study. The interviews took place at respective company with their employees and consisted both closed and open questions with our main focus on the open questions because we wanted to obtain as much information from the respondents as possible from several viewpoints.

For many years, the construction industry in Sweden has not developed much of an integral approach for design across disciplines. The sector?s impact on society, economics and environment is huge. To make the interactions within the construction industry more efficient, a relatively new concept called BIM (Building Information Modeling) has been introduced. The idea with BIM is that the different actors of the construction industry will work through intelligent CAD software, with common file formats and more cooperation between different actors during the various steps of the building and construction process.The technical consultancy company WSP Sweden is working actively to implement BIM within the frame of its activities.
