Data inom den sociala spelmarknaden
The phenomenon of social gaming is essentially an IT-service that people worldwideuses on a daily basis. This particular market is also young and generates tremendousamounts of data, which, from a data managing perspective, makes it naturallyinteresting. Throughout this thesis the social gaming market is described from the datamanaging and different actors perspectives. This is done by using literature reviewing,interviews with companies and analysis based on that information. The thesis initiallypresents important and central terms as well as different techniques.
Effektivisering av klimatskärm : a?tga?rdsfo?rslag fo?r bostadsfo?reningen Stocken
This study explores Environmental Storytelling techniques and whether these can beused in combination with each other to lead a player through a game scene in aspecific pattern, affect the player?s narrative and exploratory view and explorewhether Self-paced Exploration can be combined with these techniques.It is a qualitative study conducted by six gaming sessions with accompanyinginterviews in which six people get to play one of three versions of the same gamescene. The only differences between the scenes are the different guidance techniquesused. The informants' movement patterns are identified and interviews recorded byaudio, as well as screen recording. The results shows that Environmental Storytellingtechniques can very well be used to control the player's exploration patterns, bothnarratively and navigation purposes and Self-paced Exploration can be utilized to agreater efficiency in combination with these..
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 .
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.
Strukturerad- kontra beteendeintervju : Skillnad i mängd och kvalitet på den information som erhålls vid anställningsintervjuer
According to Barclay (2001), behavioral interviews yield higher quality information, than other interview techniques. This study focused on whether the quality and quantity of information differ between structured interview and behavioral interviewing. Two headhunters held 16 job interviews with the two techniques, 9 behavioral interviews and 7 structured interviews. Both headhunters and candidates have evaluated the interviews quantitatively. Initial and concluding interviews have, as well, been held with the headhunters. No definitive answers were found in the quantitative analysis, but the qualitative results suggest that behavioral interviews give, because of the headhunters opinions, more and higher quality information.
Om du säger det så
This study explores the different effects on attitude and behaviour three frequently used advertising techniques have. The techniques compared are social influence and egoistic and altruistic benefit-appeals. The results showed that ads featuring social influence had statistically significant higher mean values regarding attitude towards the ad compared to both the other ads, and significantly higher mean values regarding brand attitude compared to the ad appealing to egoistic motivations. Though, all advertising effectiveness measures used in this study - that is, attitude and intention variables - indicated that social influence was more effective than the other advertising messages. Thus, in accord with earlier studies, it can be stated with confidence that social influence is an effective tool to use in marketing communications..
Könsroller och Härskartekniker i Twilight : (re)produktion av patriarkalgenusstrukturer genom smäktande kärlekshistoria?
This essay aims to describe and problematize gender roles and master suppression techniques in Stephenie Meyer?s Twilight Saga. This is done in order to enable me, in my future profession as a teacher, to start an emancipatory discussion in class where pupils can become conscious of different ways of reading the love story. I will use the following two research questions to fulfil the purpose: 1) investigate which gender roles that appears in the book?s main characters Bella and Edward and 2) which master suppression techniques that colours their relationship.To answer the questions gender theory and ideology-critics are used.
Förbi Tradition och Praktik
When I was fifteen I decided that I wanted to become a blacksmith. At the time of my decision I had been obsessed with fantasy for several years. I came to the conclusion that if I could not live in a fantasy world then at least I would make bits and pieces from it. That became the entry point of my fascination for material and techniques. I started with blacksmithing since it had an aura of magic or mystique in the material and in the making process.
Att lita till läsaren : Om impressionistiskt berättande i Stig Claessons författarskap med utgångspunkt i romanen Brev till en hembygdsgård
The objective of this paper ? Trusting the reader: On impressionistic narrating in Stig Claesson's writings with the novel Brev till en hembygdsgård as starting point ? is to examine narrative techniques used by the Swedish author Stig Claesson, specifically some which fall within the broad field known as literary impressionism: e.g. omission, repetition, juxtaposition, episodic narration and how access to the narrator?s as well as individual characters' consciousness is handled.The method used for the study will be that of illustrative comparison. The analysis will seek its theoretical grounds in the works by Gerard Genette and Jonathan Culler.
Vanliga helminter hos hund, katt och häst i Sverige : artbeskrivning och laboratoriediagnostik
This report includes common helminths, symtoms, routes of infection, diagnostic laboratory techniques and prophylactic methods to prevent infection. We have pointed out where there is a risk of zoonotic transmission and how to avoid contamination and infection. We have restricted the number of species to the most common helminths. Some of these helminths do not naturally occur in Sweden (yet) but are nevertheless of current interest when we travel across borders with our horses, dogs and cats.
The diagnostic part of our report tells about different techniques to find an occurance of helminths in samples of faeces, blood, urine or saliva from a horse, dog or cat. We also write about some recommendations on treating parasitic infections and the development of anthelmintic resistant helminths that originates from incorrect use of anthelmintic drugs

Modellering av rotationssystem
This master thesis was conducted during the spring of 2014 at Atlas Copco Rock Drills AB in Örebro. 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.

Kundlönsamhetsanalys som avbildande kalkyl och medskapande praktik: En fallstudie av Billerud
In recent years, customer profitability has become a focal point of academic discussions on business performance. However, researchers remain divided as to how evaluation of customers ought to be conducted, resulting in uncertainty of how accounting systems should be adapted to prevailing conditions. This paper aims to investigate the application of customer accounting techniques and the role they play in the organisational and commercial context in which they take place. In a case study of Billerud, a Swedish company providing materials and services for packaging solutions, the interplay between customer accounting techniques and customer relationship characteristics has been examined through the application of a theoretical framework developed by Lind and Strömsten. Particular emphasis has been put on deviations from the prescribed pattern of the framework.
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.
