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 paper investigates the relation between stock performance and owner share retention in Swedish public equity listings during 2009 to 2013. The listings during the period are studied and divided into binary groups of "exits" and "non-exits", which are used in a statistical regression model to determine if there is a significant difference in average stock performance. The study finds that stocks of exit-companies on average significantly underperformed stocks of non-exit-companies during 2009 to 2013. Nevertheless, due to the limited number of observations available and the unusual market conditions, caution is required in interpreting these results..

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.

Today?s market for companies doing statistical surveys is a market consisting of mostly standardized methods where differentiating your company from the competitors is hard. Simultaneously both the society at large and technology in specific is under constant development and everything needs to be done at a faster pace with better precision. One of the companies on the market mentioned above is Tradewell Group AB. During 2008/2009 Tradewell has developed a new method for doing statistical surveys. The method named by Tradewell is called Cellphone Survey System, CSS and include using existing technology in a, for this market, unknown way.

The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.

This paper is written as an examination paper at the University of Jönköping. The subject is chosen by Peab Sweden in Jönköping with whom further cooperation has been hold. The aim is to compare building methods and building materials in Sweden, Finland and Germany for further inspiration for Peab?s own market.BackgroundThe development of the construction industry develops new materials and methods to the market which has been forced by shorter construction times and the environment aspect. To pursue the development, further knowledge exchange should exist between the countries.

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.

Manne Bouveng, CEO of Optimel AB had an idea for a new kind of storage cabinet that could be adapted especially for townhouse owners. I came in contact with Manne by a familiar friend for us; we met and decided that it would suit as my thesis.What was needed to be done was a market research that would possibly show that there was a need for a new kind of storage cabinet on the market. Because of this we continued to work on the basic idea. We came up with a solution where we developed a box that resembles Optimels known mailbox Biggi Rondo, the storage cabinet is a new solution of a storage cabinet, adapted after a market that need of a lot of new space. The solution is based on a simple construction which sits an inside hang-off device which can attach tool hooks, tool holders and shelves and so on.The purpose of the assignment was to develop a new type of storage cabinet with some kind of solution to attach tools and other garden related stuff. With this we have succeeded and the concept meets the requirements we set ourselves at the beginning of the project..

The number of LBOs in Sweden has increased during the last years and the current market trend is positive. MostLBOs involves private companies, but a few concerns public corporations on the national share market. In this thesis we will examine the conditions of a LBO of Cloetta Fazer AB. The purpose is to study existing conditions of Cloetta Fazer AB and to examine pros and cons with the deal. Based upon information presented in the frame of reference and in the empirical part, two cash flow valuations have been carried out.

In the beginning of the 1860s, an important railway was built between Malmö and Stockholm. The railway became one of the most important projects that would influence the entire southern Sweden. The railway line was located to areas outside the ordinary routes and a number of communities were built up along its way.Älmhult was one of the communities that was built up due to the railway. In the beginning there were only a few farms and a station, but a community developed and the village grew. In 1901 the village became a small market town, which was an important event.

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.

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.
