Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

This thesis was developed as an assignment from Ludosity Interactive where the goal was to develop a copy of the Xbox Live Indie Games-marketplace from the Xbox 360. Ludosity Interactive had a necessity to easily test a game's attractiveness to potential customers using testing people from outside the company in a simulated Xbox Live Indie Games test environment; excluding this developed system there is no other way to do such an analysis without actually releasing the game on the Xbox Live Indie Games marketplace and then analyze the resulting sales from the product.The finished system had to be similar to the original system to the degree that a user could see past the interface itself and use the system just as he/she would have used the real marketplace. It also had to be easy to change and add games to the system so that Ludosity Interactive easily could show the games and the data that they deemed interesting for their tests. The final product was developed using C#, XNA and XML together with an Agileinspired development method in combination with Pivotal Tracker. This report describes how this product was developed..

Reklamspel är ett verktyg inom reklambranschen, en bransch som undergått stor förändring under senare års digitala utveckling. Denna förändring uppmanar ständigt till bredare kunskap och högre förståelse hos både skapare och användare.Syftet med uppsatsen var att påbörja ett ramverk för skapandet av ?bra? reklamspel. För det krävdes att ordet ?bra? definierades och kunde förstås så att även diskussionen kring spel och reklam förbättrades.Det material som uppsatsen grundats i kommer från en två månader lång praktik där ett reklamspel producerades och från det designdokument som digitalbyrån North Kingdom lämnade efter sitt reklamspel, The Coke Zero Game.Med kvalitativa metoder samlades resultat in och jämfördes mot en teoretiskgrund byggd på kunskap inom marknadsföring, interaktions- och speldesign, användbarhet och uttryck ofta använda i spelsammanhang.

The phenomenona MMORPG-games ? a qualitative study on MMORPG-games effects on the players lifeThe aim of this study was to shed lights on what it is that makes some people play MMORPG-games, get a insight in how a gamers social network can look like and how the game can change the players everyday life. To acchieve this aim the authors carried out four individual interwievs with MMORPG-players. These interwieves was hermeneutic interpreted with the socialantropology networkstheory, roletheory, social identitytheory and the entirety was interpreted with the concept: ?the late modern society?.The conclusions that was found were that the games helps the players to handle their everyday life and has a condition for the players to produce relationships with other players.

This study has been carried out in cooperation with Unilever and partly with the EC founded project, Smartdoc IST-2000-28137. In areas of statistics and image processing, both the amount of data and the dimensions are increasing rapidly and an interactive visualization tool that lets the user perform real-time analysis can save valuable time. Real-time cropping and drill-down considerably facilitate the analysis process and yield more accurate decisions. In the Smartdoc project, there has been a request for a component used for smart filtering in multidimensional data sets. As the Smartdoc project aims to develop smart, interactive components to be used on low-end systems, the implementation of the self-organizing map algorithm proposes which dimensions to visualize.

Detta examensarbete har handlar om att ta fram kvalitetssäkringsrutiner för induktiva värmebehandlingsmetoder mot det nya mätlabbet i samband att kvalitetssäkra produktionen av drivaxlar på Volvo Component Division. Uppgiften betyder att visa hur kvalitetssäkringen av både processen och tillverkningen ska ske genom att förebygga att fel uppstår. Huvudsaken är inte hur problemet blir löst, istället kommer koncentration lagts på metoden. Det övergripande syftet med examensarbetet är att försöka hjälpa personalen i företaget komma fram till förslag och konkreta resultat i form av kvalitetssäkringsrutiner för att förbättra både produktionen och den befintliga produktutvecklingsprocessen.Främsta målet är att bygga upp en fungerande kvalitetssäkring av induktiv värmebehandling inom Component Division genom att ta fram kvalitetssäkringsrutiner som stödjer metoden. Dessa rutiner skall bygga på önskemål från kunden, detta framför allt i form av beställningsblanketter, instruktioner och checklistor. Volvo Construction Equipment AB Component Division Eskilstuna arbetar idag med en kontinuerlig process- och produktförbättring med avseende på att förebygga eventuella kvalitetsbristerna. Meningen är att man i samband med den nya utbyggnaden av fabriken, nya maskiner och ny utrustning också ska bygga ett nytt materiallabb där materialprovbitar skall kunna skickas in av operatören/teknikern för olika kvalitetsundersökningar.I dagsläget har man börjat producera drivaxlar enligt den nya flödesgruppen vars förutsättning är att artiklarna skall tillverkas från råämne till monteringsklara detaljer.

In this work we?ve been focusing on how to adjust educational computer games in order to make them suited for the educational context of upper secondary school. Our opinion and entrance to the study is that the related developers of the subject, in some ways, have failed to successfully combine and find the balance between the entertaining and pedagogical aspects in the games. Our main questions is which aspects in the games game developers need to take in consideration to satisfy the pupils, but also what qualities that is needed for them to function in their educational context. In order to do that we had to investigate the people of the target groups own perspective on what technological and social aspects in the computer games they assess as important.

The essay?s main focus has been to investigate and analyze the political actions behind the 2015?s grade compromise; an agreement to introduce grades from the fourth year in primary school. Through a game-theory analysis, mainly based in Leif Lewin?s and Jörgen Herman's research on rationality in politics, this study examined the grade debate  during a fifteen year period. The primary task has thereby been to explain the grade compromise through game-theory.

The purpose of this work is to find out if the suctionvalve to the salivaejector for dental equipment in a simple way can be improved or if a new design is needed. The result of the examination of the suctionvalve shows that the friction between the piston and the seal is high and that this causes the valve in a few cases sheaves. The study concluded that only small changes in material or detail, improve the component..

In December 22, 2010, the hockey clubs AIK and Djurgården played against each other in front of an audience of more than 11 000 people in Ericsson Globe Arena, Stockholm. Although it was one of the biggest games of the year, afterwards no one was talking about the actual game on the ice. The reason; several times during the game, hooligans from both sides started big quarrels and the hockey dome felt more like a war scene than a place for a hockey game. From a branding point of view, and along with similar incidents from the past, the night in December did not create a good situation for AIK and their image.  Therefore, in this essay I want to investigate how AIK communicated through the crisis. I also want to evaluate whether their communication was good or bad from the perspective of different crisis communication theories.The essay?s research questions are:How did media describe the crisis and AIK´s part in it?What effect did AIK´s previous history of similar problem have on the ongoing crisis?How did AIK communicate through the crisis?How was AIK´s image affected by the crisis?What did AIK do well/what could AIK have done better?To be able to answer these questions, several news articles from the sports paper ?Hockeyexpressen? has been analyzed as well as a text from AIK itself.

In this study, we have explored a new area called ?gamification? ? a word and concept that was first introduced on the Internet autumn 2010. Gamification concerns integrating game design, with emphasis on game mechanics and game dynamics, into non-gaming contexts ? such as marketing. At its basic definition, it concerns the process of transforming all kinds of activities into games.

This is a qualitative study that explores how bilingual children develop their language through play. The study is based on observations and interviews conducted in a preschool located in a multicultural area of Stockholm.The purpose of using two qualitative methods; observations and interviews, was to get a bigger picture of the study area. The results of the study, illustrated through observations and interviews that I have conducted, shows that the game has great role for bilingual children's language development. Furthermore, the results show that the informants are aware of the importance of play for bilingual children's language development especially when they are talking about investing in the promotion of children's language by using different methods and materials in their pre activity for various games and activities.One of my conclusions is that bilingual children learn the language during both free play and structured play especially when educators are present and aware of the activities that they perform. It is also important to see children as individuals to cover all the needs of children at different activities.

American football is a well-known sport in America. In addition to the design and rules of the game and the surface it is played on, there are also other differences that are not directly visible. One difference noted in this study is how the teams in the game provide players. Each team has a board of directors together with the team's leadership and they will determine which players are most suitable for the team. These players are recruited to the team after graduating from a U.S.
