In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

I have with this thesis sought to understand how chick lit could be useful in the classroom in the teaching of Swedish B-course in high school. Based on the model of critical literacy I am arguing that this genre would help to meet the objectives of the policy documents which, among other things, are to critically examine and analyze various types of texts.I have found that some of these texts could be used for analyzing and critically examine the ideological dimensions of texts and cultural heritage by the model of critical literacy, and also as a counterweight to the more traditional teaching of the canonical literature as a literary historical stuff that students should learn. I have also wanted to create a basis for discussions about literature in the classroom based on the chick lit genre. To do this I have, based on three themes and questions from the model of critical literacy, tried to focus on issues that might emerge from the ideological analysis and critical review. The model aims to deconstruct norms of society, and in the work of chick lit, I wanted to show how you could deconstruct norms around gender..

Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

This thesis explores different ways of navigation in virtual environments. It also investigates how virtual environments can support human memory. Tests are done using a self made virtual model of Orkanen Library, Malmö högskolas school library. Among the different navigation tests that were done, a visual guidance in form of a line on the ground leading to the goal is showed superior when navigating a virtual environment but that people prefer legible landmarks instead. Tests were also done which show that a 3D-model of a real location supports context based memory.

The concept of leadership development plays an important role within the modern organization. As a result of the increasing interest in developing leadership competencies, investments in leadership development programs are becoming a common part of business strategies. However, the return on those investments is seldom evaluated. The reason for this is considered to be the complexity created by the many factors that influence leadership but have no relation to the program. This is a case study based on interviews with participants from a one-year leadership development program that was carried out at AB Previa.

The term "Project" have become a growing work model that exist in almost all bransches. A project is a work effort made over a finite period of time with a start and a finish to create a unique product, service, or result. Science shows that time limitation has an impact on humans to perform under pressure, which challanges the contributor to deliver. This report contains an examination about project management, both coming from scientific results and an external business. The point of this study is to bring ideas of improvement, which can make the work method more effective in this company..

The purpose of this thesis is to construct a marketing model to be used both theoretically and practically when working with marketing in Swedish public libraries. This objective is achieved by first making a literature review of the written works on the marketing of libraries, and then studying the marketing activities at the public library in Bollebygd, Sweden. The theory is based on the marketing mix model the 7 ps, which serves as a framework for the presentation of the empirical result and the analysis. One of the questions posed in the beginning of the paper is how the library has worked with marketing over the past ten years. Through a combination of methods observation, textual studies and interviews the marketing activities employed at Bollebygds library are noted.

Elektronisk handel är en av de starkaste trenderna inom IT-området just nu. För företag som är snabba på att tillgodogöra sig och bemästra tekniken öppnas nya dörrar mot nya marknader. Det är viktigt att företagen förstår att elektronisk handel inte bara är datorer, programvaror och nätverk utan att det handlar mer om affärs- och organisationsutveckling.Detta examensarbete behandlar ämnet elektronisk handel mellan företag, business-to-business.Syftet med denna rapport är att belysa hur långt de medelstora tillverkande företagen i Sverige kommit i processen att införa elektronisk handel.Undersökningen, som bedrevs för att erhålla svar på problemformuleringen, genomfördes med hjälp av intervjuer via telefon och personliga besök samt utskick av enkäter till företag.Resultatet som undersökningen genererat är att intresset för elektronisk handel är väldigt stort inom den utvalda kategorin, svenska medelstora tillverkande företag. Även om det är ett stort antal företag som hittills inte har infört elektronisk handel så var majoriteten av de undersökta företagen intresserade av ett införande..

This study aims to measure the effect of accounting conservatism and to identify thebusiness activities causing firms to undervalue owners? equity. To estimateaccounting conservatism, we have followed the hypothesis that no firm over time cangenerate a return greater than its cost of equity, i.e. CAPM. Thus, if a firm in factgenerates an excess return over time, we assume that the excess return is an estimateof accounting conservatism within that firm.The hypothesis originates from the corporate valuation model ?Economic ValueAdded®? which tries to adjust for accounting bias.

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

Procedural Content Generation innebär att spelinnehåll genereras automatiskt för att dels minska arbetsbelastningen hos designers men också för att öka variationen i spel. Ett användningsområde för detta är rumsbaserad bangenerering där banor byggs upp av fördefinierade rum. Målet med det här arbetet var att implementera och jämföra tre olika algoritmer som kan åstadkomma detta; Binary Space Partitioning, Shortest path och en evolutionär algoritm. De kriterier som algoritmerna utvärderades på var tidseffektivitet, variation och möjligheten att nå alla rum. Resultatet visade att Binary Space Partitioning och Shortest path var de två algoritmer som var bäst lämpade att användas i ett spel där genereringen ska ske under körtiden.

The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.

This thesis work contains a litterature study about electrical motors in general and how PWM-patterns for brushless DC-motors can be made. A suitable method has been implemented as a simulation model in VHDL. A simulation model of a brushless DC-motor which describes the phasecurrents, torque and angular velocity has also been made. The motor model made simulations easier for the complete PWM-system. The design was synthesised and tested with a prototypeboard including a SPARTAN II FPGA.

Managing credit risk might be the single most important business area for any commercial bank. The assessment of "good" and "bad" corporate clients is a important task for a creditor. A bad debtor is a corporate client with hardships in meeting the continous claims (interest payments) that a creditor requires. One way of evaluating or separating a "bad" client from a "good" client is to assess the propensity for the client to file for bankruptcy. This thesis examines 226 firms in the Swedsh market in the quest of predicting corporate bankruptcy.
