The Swedish do-it-yourself (DIY) market has expanded in recent years and is today a SEK90 billion market. Competition is fierce, however, and the DIY retail chains compete over market share with extensive marketing campaigns. Advances in computer technology have made it possible to acquire and compile huge quantities of point of sale data. However, due to a lack of economic theories and statistical methods, this data cannot be effectively utilized and the effects of the campaigns are not measured in any detail. In this study a new method was used to examine the effects of marketing campaigns in the DIY consumer market.

This study investigated how banner ads, depending on its quality and placement,can capture a user's attention while searching for editorial content in an online newspaper. Furthermore, the user's search strategy was also studied to see whether it varied depending on the placement of an ad. An experiment was conducted where 20 subjects searched for articles in a Swedish online newspaper while their eye ovement was recorded with a headmounted eye?tracker. In each search task the online newspaper contained either a low quality ad or a high quality ad.

Most often when developing a new system there is a need get a functioning testtool up and running. Including time, cost and resources the solution isn?t always obvious, developing your own or buy one ?of the shelf?. The purpose of this thesis is to study how a general testtool for executing functional tests should be designed to be reusable, be based on recognized knowledge and be able to fast and simple be customized for different types of systems. Key functions from the litterature is presented and used in the design of a testtool prototype.

Målet med denna rapport är att ta reda på hur lång en attackanimation i ett spel kan vara innan spelaren blir frustrerad över att den tar lång tid. Forskningen inom dataspelsutveckling är fortfarande begränsad, men det finns mycket att hämta från området Human-Computer Interaction. Undersökningen genomfördes på 22 personer med spelvana. De fick spela en av två versioner av ett fightingspel som utvecklats speciellt för undersökningen, sedan fick de svara på en enkät om hur de upplevde spelet och attackerna. Deras knapptryckningar under spelandet loggades.

The conception of exhaustion was first used in the end of 1960 and was then used in a psychological context directed towards the working life. Eventually was the conception devided into two main categories: mental and somatic symtoms. Today research of exhaustion is mainly aiming towards recovering and returning to working life.This work sets out to analyse the importance and effects of social networks such as family, friends and professional relations in helping people who suffer from exhaustion to recover. The study is based on interviews with eith people who have suffered from exhaustion but today are recovered. To my aid I have used tree different questions: What part have the social network of family and friends ment to the recovery? What part has the professional relationships with doctors, therapists and curators ment to the recovery? How have you changed your life in order to maintain balance?The interviews pointed out the importance of the social relationships as support, feedback and understanding that the process takes time.

Microproduction, also called distributed generation, is something that has become more and more popular in the electric grid. Microproduction can however lead to unacceptable performance if several units are installed in the same low voltage network. It is therefore good to know a limit where the performance of the low voltage network becomes unacceptable based on given parameters. This limit is usually called hosting capacity.In this report the hosting capacity with respect to voltage and current have been studied in three low voltage networks which are located in Falu Elnäts concession area. This has been done by simulations in a GIS-program where critical times of the grid have been simulated.

The theses discuss information seeking with a focus on Google and social networks. Students attending the librarian program in Lund have been examined by means of two methods; diaries and information horizons, where they had to solve a specific assignment. The information horizon as a method contributes to getting a structural perspective on the information search process instead of viewing information search as a procedure. Information horizons use social network analysis.The aim of the theses is to investigate the importance of the social network in information search, with a particular focus on Google as a search tool. Our hypothesis is that Google acts as a compensator to the social network when the students search for information and in the educational program.The research indicates that there is no direct correlation between usage of the social network and usage of Google.

BCI (Brain Computer Interface) för användning i spel har börjat dyka upp på konsument-marknaden. Dessa använder ofta EEG för att mäta spelarnas avslappningsnivåer och den spelare som lyckas nå högsta meditativa tillstånd samlar poäng. I detta arbete undersöks huruvida det går att använda BCI för mer direkt kontroll av en specifik spelmekanik i kombination med konventionella spelkontroller. För undersökningen har två versioner av ett spel skapats med avsikten att mäta skillnaden i hjärnaktiviteten hos spelare som bara spelar, jämfört med spelare som aktivt försöker åstadkomma ett specifikt sinnestillstånd för att direkt kontrollera en funktion i spelet. På grund av studiens begränsade omfattning kunde inga definitiva slutsatser dras men det finns indikationer på att MindWave, som var utrustningen som användes i denna studie, inte är lämplig som direkt kontrollmetod tillsammans med andra kontroller.

Mobile telecom and the Internet are converging, which opens new possibilities for market actors to create business through the mobile handset. At the same time market experts are predicting that mobile operator?s existing dominance in the telecom market will in the future decline as new technology such as VoIP and services will erode the operator?s traditional revenue model. This implies that mobile operators will need to rethink their dominant business logic to create new value for their customers. Mobile operators are aiming to expand their existing revenue model through advertising in the mobile handset and are searching to create new business models that evolve advertising sales.

Efter fyra månader som ljudpraktikant på det svenska spelföretaget Starbreeze i Uppsala, var det dags att ta steget vidare i ytterligare fyra månader. Från ljuddesign till scriptning, idéer och tankar, samt en inblick i hur scriptning fungerar. Detta arbete handlar om framtagandet av en ljuddesign-prototyp åt ett externt företags framtida spelprojekt. En utveckling som från början var tänkt att öka kunskaperna om scriptning, och att skapa ett sammanhängande spelscenario, men som sedan utvecklades till att leda mycket längre. Förklaring: Ljuddesign = Ljudläggning av någon form, i detta fall spel. Scriptning = Enklare programmering, kan vara saker som händer eller saker man kan göra i spelet Nyckelord: Soundvolume 2.0, Starbreeze, ljuddesign, spel, sounddesign, 3D.

Problem: Our opinion is that it is important to consider about usability in system development. In this thesis we will focus on usability in point-of-sale systems. The point-of-sale system we base this thesis on is Extenda Retail. Our case study is performed on Ica Kvantum in Bromölla, which implemented Extenda Retail about two years ago. Purpose: The purpose of this thesis is to figure out what important factors there are to consider, in usability aspects, when developing point-of-sale systems, with focus on the cashier. We also wish to find out the cashiers opinions about the Extenda Retail system. Method: The information gathered for this thesis consists of literature and interviews.

The essay's aim is to explain how responsibility distribution between private and public bodies, primarily within three important service areas, can be visualised in light of the fact that they have experienced different forms of readjustment. We have chosen to study this by looking at the restoration work taking place after the hurricane Gudrun swept across southern Sweden on January 8-9, 2005; and we have chosen to concentrate on the service areas of electricity- and telephone supply, and public transport. The responsibility distribution has been depicted by carrying out qualitative interviews with employees within both private and public bodies included in the restoration work. The conclusion produced is that there were obscurities in the formal responsibility distribution between private and public actors taking place in conjunction with the hurricane restoration work.In a deeper analysis, the result can be explained by a ?several hands? problem arising since the number of actors has increased as the public sphere has adopted leadership forms influenced by the private business sector.

This thesis describes a system for dealing with free surface fluid simulations, and the components needed in order to construct such a system. It builds upon recent research, but in a computer graphics context the amount of available literature is limited and difficult to implement. Because of this, the text aims at providing a solid foundation of the mathematics needed, at explaining in greater detail the steps needed to solve the problem, and lastly at improving some aspects of the animation process as it has been described in earlier works. The aim of the system itself is to provide visually plausible renditions of animated fluids in three dimensions in a manner that allows it to be usable in a visual effects production context. The novel features described include a generalized interaction layer providing greater control to artists, a new way of dealing with moving objects that interact with the fluid and a method for adding source and drain capabilities..

In this paper we have studied how young adults read news on the internet. The purpose was to seehow the consumers of news were irritated by the adverts on news sites depending on whichplatform they used, a computer or an portable reading device of the brand Apple iPad. Observationsand surveys were conducted on ten people. The news sites we used for this study were www.SvD.seand www.expressen.se. The result show that a majority experienced that their news consumptionwere irritated by advertising, mostly on Expressen's news site because it wasn't perceived asforeseeable..
