The costs often exceed onehundred percent of the annual salary for the otherwise vacant position. In addition to thedirect costs of employee turnover troubles, things such as work confusion, loss oforganizational memory along with strategic skills can arise. The employee turnover rateof Trygg-Hansa?s outbound department in Växjö is too high according to the officemanager.Purpose: Understand the causes of high employee turnover in a Swedish insurancecompany.Methodology: This thesis consists of an ethnographic study of a Swedish insurancecompany.

The actual project presents the development of a testing rig for a steam engine. A short overviewabout the development of steam engines is presented, until arriving to the development of thepresent engine, which will require to be tested in different ways.The testing rig studied on this project (based on a Lanchester engine) will be used to testdifferent materials and layouts for the group Piston-Cylinder.The engine is a high performance steam power engine, which is going to have a highpower/dimensions ratio, what will lead to require high performance components and materials.An introduction to the testing rig is presented, and the entire design project is done in order toreplace the disappeared documentation of the current testing rig, built on the 1970?s. Also somemodifications done in the original testing rig are presented, as well as some detected problemsand their possible solutions..

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.

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..

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..

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".

Behovet av att analysera volatilt minne från Macintosh-datorer med OS X har blivit allt mer betydelsefull på grund av att deras datorer blivit allt populärare och att volatil minnesanalysering blivit en allt viktigare del i en IT-forensikers arbete. Anledningen till att volatil minnesanalysering blivit allt viktigare är för att det går att finna viktig information som inte finns lagrad permanent på datorns interna hårddisk. Problemet som låg till grunden för det här examensarbetet var att det uppenbart fanns brist på undersökningsmetoder av det volatila minnet för Mac-datorer med OS X.Syftet med detta arbete var därför att undersöka möjligheten att utvinna information från ett volatilt minne från en Mac-dator med OS X genom att kartlägga och bedöma olika undersökningsmetoder. För att göra denna undersökning har litteraturstudier, informella intervjuer, egna kunskaper och praktiska försök genomförts.Slutsatsen blev att möjligheten att utvinna information från det volatila minnet från en Mac-dator med OS X är relativt begränsad. Det största problemet är själva dumpningen av minnet.

During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

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.

Abstract Squares, these public rooms have always fascinated me. I find them interesting because of their variety in shapes, functions, design etc. Stortorget in Lund is one of Sweden?s oldest squares, this essay is dedicated to this particular square. Of all the possible ways that you could approach Stortorget in Lund I have decided to do it from an urban design point of view.

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.

The location on the river delta of Klarälven, adjacent to lake Vänern, makes Karlstad one of the Swedish cities where a significant flood risk is present. The city has several major floods in its memory which has caused great material damage and economic losses, the latest of which occurred in the winter of year 2000/2001. The purpose of the study is to examine how the approach to flood risk has changed in the municipality of Karlstad since the 1950s, and how this change has affected the current situation regarding the city's vulnerability to flooding. To investigate this, a document analysis was conducted, where key documents in the media and from the municipality of Karlstad was studied. Furthermore, an interview study was conducted with respondents who currently are employed or previously have been employed in the municipality of Karlstad, who in various ways work with issues of flood risk. The result of the study shows that several changes have taken place since the 1950s in terms of the municipality's approach to flood risk, which for instance has led to preventative measures being taken to a greater extent than previously in the physical planning.
