Robotiserad produktionsanpassad magnetmontering för vågkraftverk
This thesis work includes studies and simulation how magnetization of the translator in a linear generator for wave power can be automated. The translator is the moving component in the generator that is "dressed" with permanent magnets. The translator is magnetized with rectangle-shaped permanent magnets that are today's strongest permanent magnet type of neodymium-iron-boron (NdFeB).Eight equivalent metal sheets are mounted around the translator. The plates have milled tracks where 106 permanent magnets per sheet are mounted. Today the assembling of the magnets is done by hand, which is a very tedious and time-consuming work. This project presents investigations about the automation of the translator magnetization theoretically and simulation results are preformed in ABB's robot simulation software RobotStudio. Even robot-held tool was designed that enables the robot to be able to magnetize the translator in a simple manner. The investment cost is roughly 1.5 million SEK. With an economic life-time of five years, the investment costs are estimated to 24000 SEK / month. According to the calculations, this project is very motivated to implement, as it provides savings up to 17 000 SEK per translator which is 10.2 million SEK assuming that the robot cell is operating at full speed the whole year.According to this thesis work the result is a 4x9 meter cell with two industrial robots of the type ABB IRB6650S.The cycle time to magnetize one translator was calculated to about 10 hours.This prototype of project can possibly be implemented in a full-scale production line and performed according to the calculations and simulations presented in the report. Further work is suggested to improve the tool.Lyssna .
I en värld av uppköp och fusioner : En studie av personalens upplevelser av integrationsprocessen vid ett företagsuppköp
Problem Are there any abnormal changes in the parent company's share price at the news of a spin?off.ObjectiveThe main purpose of the study is to investigate how the news of a spin-off affects the parent company's share price. In other words if the news of the Spin-off gives an abnormal return on the Stockholm Stock Exchange during the specific period of 1998?2008. In addressing this, the paper will also investigate the following sub sections: are there any differences in the abnormal returns in various sectors and what the reasons to perform a spin?off in the Swedish market are.MethodAn event study in which market data is used to measure specific events? impact on the value of the company and on the effects on the stock market.
ADS och Matlab för optimering av pre-distortion av effektförstärkare
This master?s thesis deals with integrating simulations using Agilents Electronic Design Automation tool ADS with customized Matlab scripts, for solving complex analog and digital radio architectures. In particular, it addresses predistortion, realized in the digital domain, of power amplifiers, modeled in the analog domain. The former is implemented in Matlab while the latter is implemented in ADS. Two versions of integrating the two systems have been tested: 1) Iterative approach on sample basis and 2) Scheduled batch solution by matrix inversion.
Modell och analysverktyg för beräkningav frekvensförlopp
The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.
Kulturevenemang på folkbibliotek
This thesis examines art exhibitions, literature events and music events in public libraries in Sweden. The aim is to study which event occurs most in the libraries in Sweden. I also examine who takes responsibility for the events, who the libraries engage, how much the events cost, and how often the libraries have the events. I also study Swedish cultural politics in purpose to see if the libraries follow the aims and directions decided by the Swedish government. One aim of the Swedish culture politic is to give every citizen in Sweden the same possibility to experience culture, no matter where they live.

Har en kortinnehavare skadeståndsansvar vid obehörigt användande av kontokort?
The purpose of this essay is to elucidate if there is a liability to damages for cardholders, in case of unauthorized use of bankcards, in the event a liability for payment, according to 34 § the Swedish Law concerning Consumer Credits, should not be established between card issuer and cardholder. The purpose is also to elucidate if card issuing companies, in the event a liability for payment is established between card issuer and cardholder, have any possibility to get a larger sum than is allowed by 34 § the Swedish Law concerning Consumer Credits, by demanding damages from the cardholder. Finally there is a judgement of how a court could do if it wanted to hold a cardholder liable to damages because of unauthorized use of bankcards..
Event i relation - vilka komponenter bör ingå i en bra relation mellan kund och eventföretag?
Vid köp av en upplevelse får du enbart en tjänst, med ett löfte omett mervärde. Att köpa en upplevelse är ofta förknippat med enviss osäkerhet och ett risktagande från kundens sida då man intemed säkerhet vet vad man köpt förrän efter arrangemanget ärgenomfört. I eventbranschen hittar vi denna typ av problematikoch därför har vi valt att fokusera på eventföretag och desskunder. Syftet med detta arbete är att undersöka vadföretagskunden värdesätter och förväntar sig i en relation medeventföretag. Vi har utgått ifrån frågeställningarna: Vadvärdesätter och förväntar sig företagskunden i utvecklandet av enrelation med ett eventföretag? Vad värdesätter och förväntar sigföretagskunden i en befintlig relation med eventföretaget?Påverkas eventföretagets relationsmarknadsföring av kundensförväntningar och i så fall hur?.
Att skapa en konceptdesign av en webbplats för ett evenemang : Att ta fram en design av en webbplats med en grafisk identitet ur ett marknadsperspektiv
Internet and social media have opened up new possibilities for companies and organisations tocommunicate their brand. It only takes a few seconds to communicate the message of a website to theuser. This indicates the importance of having the intended message of the website communicated clearlyin order to give the user a correct impression of the company or the organisation. When it comes to theconcept design of a website, it?s important that all different parts is presented uniformly.

The purpose of the thesis was to develop a simulation model of the rotation system for a hydraulic rock drill. In the future, the model will be used to investigate the phenomena called ?jerky rotation?. In order to validate the simulation model a test bench was designed and tests were made.
En event study av reporäntans effekt på aktiemarknaden
Det är av intresse för aktörer på den finansiella marknaden att prognostisera aktiemarknadens reaktion på en ändring av reporäntan. Flera arbeten har de senaste årtiondena försökt påvisa ett samband främst på den amerikanska marknaden. Denna uppsats försöker sig i stället på att finna en korrelation mellan annonsering av reporänta såväl som förväntningar på reporänta och en onormal avkastning på den svenska aktiemarknaden. I arbetet används en event study på Affärsvärldens index under perioden 1997 till 2007. Perioden är vald så att det initiala trovärdighetsproblem för riksbankens inflationsmål som förelåg före 1997 inte ska påverka resultatet.
För Sverige i rymden : Fuglesang, föreställningar om rum och svenskhet
The senior essay examines the geographical imaginations, notions of Self and community that were mobilized in the media and by the government in conjunction with an event, namely, the space voyage of Christer Fuglesang ? the first Swedish astronaut in space on December ___ 2006. The study is a critical investigation of media discourses, representations of space, and geographical imaginations that were triggered by the event. The specific issues addressed by this study are (a) which representations of Sweden were mobilized in narrating the event? (b) In what ways has Fuglesang´s space voyage influenced the image of Sweden? (c) How was the event rallied vis-à-vis discourses of entrepreneurial culture and neoliberal growth by the government? (d) Which themes and clichés were mustered in the media dramaturgy of the event? (e) Which topics were excluded in media narratives and representation of the event? (f) Have familiar geographical imaginations, notions of Self and community been reconfigured? If so, how?The present study analyzes narratives of the event in the two largest newspapers in Sweden - Aftonbladet and Dagens Nyheter, as well the two biggest TV-channels ? Swedish Television and TV4.
Event Marketing : En alternativ väg till kund lojalitet
Marks do not only work as an acknowledge of the effort that has been made under a long period of time, but also as a receipt for eligibility to further studies. Within the political debate, marks have often caused a big discussion among the political parties. That is due to the obvious difference between the political parties on the left, and their counterparts on the right. However, there is one thing that they all have in common. Everyone of them have plans of measure within their political agenda, regarding the use of marks.The aim of this study has been to try to understand the way pupils think about marks.
Analys av instyrning och rolldynamik
When driving hard and cornering on a circuit good control of a car?s roll is desired, so the car reaches steady state quickly but yet in a controlled fashion. This control is mainly given by the combination of the cars springs, shock absorbers and anti-roll bars.The aim of this report is to investigate, analyze and measure a Porsche Boxster?s turn in behaviour and roll dynamics as well as with the aid of simulation results give suggestions for improvement of the previous mentioned combination.Two different simulations were made, one based on a simpler model that was based on an evolved version of the bicycle model in Matlab and one was more advanced model in the simulation software rFactor. Measurements of the real car was made using a GPS-based measurement system.
Valresultat och börskurser : En eventstudie om riksdagsvalens effekter på Stockholmsbörsen
Background:It is always fascinating to observe the events that affect the stock market, especially as the numbers of influencing factors are so many and various. Political elections are important events in society and affect the corporate environment in different ways depending on which political party that is in power. This brings up the question of whether political elections are important enough to affect the stock market; and it is this question we intend to analyse in this paper.Purpose:The purpose of this paper is to investigate whether political elections affect the stock market and to discuss the reasons for any possible affect that might be found.Procedure:An appropriate and thoroughly tested method to investigate if an event affects the stock market or not, is to do an event study. Subsequently we chose to do an event study on whether the Swedish general elections in 2002 and 2006 affected the Stockholm Stock Exchange. In order to give the analysis more depth we have also chosen to interview people with knowledge of the stock market.
