Induction motors, often referred to as the workhorse of the industry, play an important role in production today. Therefore, it's important to diagnose any faulty induction motor prior to failure to avoid costly and time consuming production stops.This thesis compares methods for diagnosing induction motors in operation, MCSA, Park's vector approach and the standard method used by Swedish industries today. By simulating broken rotor bars and short-circuit in one of the windings, each method is tested and the results are compared using matlab.The results need further verification due to uncertainties of the condition of the test motor, even though the experiment gives a hint of the different advantages of each method. A combination of the methods should be able to tell if the motor needs further examination..

Background: It has been shown that companies that lived under protected conditions for a long time have had difficulties to adapt to major changes. With that in mind an even more extensive low-cost competition in the Swedish grocery market will make a threat for the traditional grocery stores' long-term survival. The question then becomes, which strategies will be successful and lead to higher customer loyalty.Problem: Are the traditional grocery stores using strategies that can compete in addition to pricing and will those strategies lead to long-term survival?Objective: Is to analyse and evaluate two traditional grocery stores' strategies and to examine whether these are consistent with customer demand.Approach: First we have created a more fundamental understanding of the situation in the Swedish grocery market. Then we have implemented two interviews in each grocery store.

Background: The parent has a natural presence in today?s child health care and hospital treatment. The transition from home to a care institution has an impact on the parent. Previous research shows that over time the conditions and the parent?s role in child and youth health care have changed extensively.

GPGPU is a collective term for research involving general computation on graphics cards. A modern graphics card typically provides more than ten times the computational power of an ordinary PC processor. This is a result of the high demands for speed and image quality in computer games.This thesis investigates the possibility of exploiting this computational power for image processing purposes. Three well known methods where implemented on a graphics card: FFT (Fast Fourier Transform), KLT (Kanade Lucas Tomasi point tracking) and the generation of scale pyramids. All algorithms where successfully implemented and they are tree to ten times faster than correspondning optimized CPU implementation..

The swedish law of contract is fundamental within several civil law areas, among others labour law. The labour law contains more explicit legislation specificly adapted to the relation between employers and employees. Sometimes the labour law needs to rely on more general regulations, such as the law of contract. When the situation contains a specific contract relation dilemma it is logical to use the law of contract, when for example the law of employee protection does not reach an acceptabel solution.Transfer of undertaking is a situation were the employee protection is disregarded. The Euro directive 2001/23/EG prescribes, by its implemented rules in the law of employee protection, that rights and duties, such as employement agreements, passes on to the earner of the business.

I have always been told that form follows function. But does it have to be that way? I decided to see it  from another angle.Kinesics is a term form non verbal komunication. In my thesis project I have been working with body language in furniture.  I believe that furniture, just like us, has an expression and a character. We often tend to desccribe furniture with the same words as we describe people, for example: "A relaxed chair" or "a cocky table".

The amount of mergers and acquisitions between international and Swedish actors increased due to the Swedish entry in the European Union. In many cases, conflicts between manage-ment and employees made visible the cultural differences between nations and organisations. As a result of these conflicts many companies experience difficulties in operating on the Swedish market and in some cases they have even been forced to leave it.The starting point of this study is analysing how the management at a foreign company in Sweden, that has undergone a merger, has been affected in the meeting with the Swedish business culture. The analyse has got three different perspectives as a base; management, market knowledge and culture.This study is accomplished on the basis of a deductive approach. It is a case study where the empirical foundation derives from five interviews.

Each year, Heterobasidion spp. is a major cause of economic losses to forestry in the northernhemisphere, including Sweden. New results indicate that pre?commercial thinnings could be at riskfor Heterobasidion spp. infections.

Over the course of the past the agricultural sector has been characterized by radical market changes. Changing market conditions have forced owners of agricultural and forestry businesses to make further investments. This increase in investments has led to a greater need for external capital, which has increased the relationship between banks and owners of agricultural and forestry businesses. The financial sector is characterized by strong rivalry, which forces banks to create strategic positions in the financial market. Since agricultural and forestry businesses are generally seen as secure customers by banks, due to high property and land values, the competition between banks with agricultural and forestry businesses as customers has amplified.

The aim of this work was to find out what potential contaminants from roads, residential area and businesses within Svedens industrial area that can affect groundwater quality and quantity. Data collection was from SGU, VISS, internal material from Gävleborg county Administrative Board and Gävle municipality archive. GIS software ArcGIS was used to create the map images in the work. The studied area is located approximately ten kilometers west of Gävle city and consists of the esker Valboåsen, which is a glacifluvial deposit that in its central parts consist of coarse material that is overlaid by sand, clay and silt. North of esker Valboåsen there are the river Gavleån which has an inflow to the groundwater in the esker. This inflow represents the largest part of the groundwater recharge.

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

The aim of the present paper was to see why a recommended course of action is not always followed in the way it is supposed to. The paper deals with a new method (SFA-metoden) used by The Social Insurance Agency in working with sick-listed people. Aspects that are elaborated on are local effects of the method at its introduction, case managers work conditions, and control of the implementation of the method. Two different methods of investigation have been employed. On the one hand, previous reports on the method have been analysed, and, on the other hand, two focus groups interviews, one consisting of case managers´ working with the method, and one constituted by their supervisors have been carried out.The results have been analysed in accordance with, on the one hand, the theory of street level bureaucrats and, on the other hand, certain concepts applied in the new institutionalism.

The aim of this diploma work was to obtain a review of the appeal process in Sweden under the Planning and Building Act and the possibilities of appeal in the planning and building permit process. The work was intended to identify potential problems surrounding the appeal process and possible efficiency measures. The goal was to form a report that provides a satisfactory overview of the appeal process in theory and practical application as well as provide relevant concrete proposals on how the appeal process can be streamlined.Background and facts surrounding the work were taken from different types of literature and through several interviews with representatives in government, industry and politicians.The main problems related to the appeal process are in the long processing times and the high number of appeals. There is a great interest to streamline the appeals process and the government is going to launch studies in which possible future actions will be investigated.It is possible to appeal for up to two instances before you need a so called ?leave to appeal? in order for your complaint to be passed on to the next instance.

Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.

Lumilos is a work investigating the possibilities to use light and color in an interactive design context. I have explored different light sources and compared them to each other and given a short description of the history of light and how it has been developed during the industrialization in the western world. I have also investigated what is currently done in the field and summarized that with examples in the categories passive-, colored-, material- and interactive light. The conclusion is that working with interactive color and light is a hard task. There are many different angles to take into account such as personal likings and earlier experiences that is uncontrollable by the designer. Yet there are many possibilities and light is a material that is moldable in many forms. I have put the knowledge about light and color into practice and developed an interactive light wall that is visualizing energy consumption with the use of different colors of light and animations.
