The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

With this study we aim to learn more about the process in creating an identity onFlashback Forum. We have observed four members of the forum to find what themesdefine thier way of making an identitity. Besides to our empirical material we foundearlier research that could support our study. The methods we used was qualitativesince we wanted to get a deep understandning for their behaviour. We found thattheese three themes were central: Language, Content and the feeling of beingAnonymous.

Mandometer® är ett medicinskt hjälpmedel som används för att normalisera ätbeteende hos personer med övervikt och ätstörningar. Mandometer® har utvecklats av Mando Group AB och används i behandling på Mandometer- och Mandoleankliniker i Sverige, USA och Australien. Det har nyligen skett en utveckling av Mandometer® från generation fyra till generation fem. Den nya versionen består av en tunnare våg och en mobilapplikation, istället för en våg och en bärbar dator. Det finns ingen tidigare studie kring den nya versionens användarvänlighet.

This qualitative study is done with the purpose of creating understanding for the theoretical democratic content in educational materials for Civic Education courses 1a1 and 1b during GY-11, so teachers create an intentional approach when using educational materials in their democratic education. This was motivated as important considering the reduction in obligatory Civic Education for the vocational programs. The study was conducted using a hermeneutic qualitative reading method where the educational materials, more specifically two series with one book for each course, was read with purpose of creating understanding for the democratic content according to ideal democratic models: deliberative democracy, participatory democracy and electoral democracy. A text voice analysis was also conducted using Bakhtins theory of dialogic and monologue text that contributed to the general result concerning the democratic content. The results show that the electoral democracy ideal is dominant in all educational materials, there is hence no striking difference between the democratic content in 1a1 and 1b educational materials.

Fondsparandet har länge varit den dominerande sparformen i Sverige. Totalt ägnar sig hela 74 procent av Sveriges befolkning åt aktivt fondsparande, och andelen blir högre vid pensionssparande. Tendensen är tydlig, svenskar ägnar sig allt mindre åt att själva äga aktier och har i stället överlåtit sparandet till banker och fondförvaltare. Storleken på en aktiefond har stor betydelse för vilken strategi en förvaltare väljer. Tidigare studier har funnit att det finns skillnader mellan förvaltad fondförmögenhet, avkastning och risktagande.

Purpose/Aim: The purpose of this thesis is to define and analyse how Swedish record companies work with digital musical content distributors. A more narrow aim is to show how the record companies and with the digital musical content distributors iTunes Music Store and Spotify create incentives for consumer?s to use legal digital music channels through the Internet. To further circle the core of the problem following questions have been asked: How does the record companies provide iTunes Music Store and Spotify with digital content and what is done by the record companies to retain control over the material? How do the record companies view digital musical sales and what incentives are given to consumers to buy music digitally? Finally, What position of power do iTunes Music Store and Spotify have on the digital content arena?Material/Method: The data collected for this thesis is retrieved through personal interviews with representatives from three of the four major record companies Universal Music, Warner Music and EMI and their Swedish branches.Main results: The consumer?s access to digital content through iTunes Music Store and Spotify is of the utmost importance and is a prerequisite.

Problem definition and purpose: A debated question in journalism today is if the mass media have the power to affect norms and values in the society. There are therefore many who believe that the media must works for democratic and equitable news coverage. Studies have shown that there are still many differences in how women and men are being portrayed in the Swedish media, even if Sweden is one of the most equal countries in the world. This inequality may affect the democracy and equality in the society negative.Previous studies have mainly been using gender as the only explanatory factor to explain the difference of coverage between men and women in the news content. The purpose of this study will therefore not only be to compare the coverage of the Green Partys two spokespersons, Åsa Romson and Gustav Fridolin, from a gender perspective but also to take in count other factors that could contribute to differences in the news coverage.Method and material: To find an answer to the purpose of this thesis a quantitative content analysis have been done on a total of 238 news articles in which Åsa Romson and/or Gustav Fridolin occur.Main results: The results of the content analysis show that Gustav Fridolin occurs more frequently in the news than Romson does, and that the articles he appears in is lager than the articles in which Romson appears.

In a sustainable society the use of renewable energy and recycling of materials is of high importance. Wastewater treatment plants use large amounts of energy in the processing of wastewater. This study seeks to evaluate wastewater as an energy resource and to examine treatment plants potential to become sustainable energy producers. The study is based upon the internal processes of Himmerfja?rdsverket.

Syfte:Att undersöka hur den yngre generationen (19-29 år) upplever att bankerna arbetar med marknadsföring gentemot dem. Vidare är vårt syfte att undersöka hur den yngre generationen upplever deras relation till bankväsendet, och vad de anser är viktigt i valet av bank.Forskningsfråga:Hur upplever den yngre generationen att bankväsendet arbetar med relationsmarknadsföring gentemot dem?Hur beskriver den yngre generationen sin relation till bankväsendet?Vad anser den yngre generationen är viktigt i valet av bank?Metod:Att utifrån ett deduktivt vetenskapligt synsätt genomföra en enkätundersökning på en population som representerar en yngre generation samt att genom observation klarlägga och analysera bankväsendets användning av sociala medier, webbsidor och kundbemötande.Slutsats:Bankväsendet ägnar sig inte åt ett relationsmarknadsföringsarbete som den yngre generationen upplever som tillfredsställande och tillräcklig. Undersökningen visar att den yngre generationen beskriver sin relation till bankväsendet som relativt avlägsen. Den yngre generationen är också relativt eniga om att det allra viktigaste vid bankval är att känslan av förtroende för personalen och upplevelsen av att banken kan se människan som en enskild individ. .

ABSTRACT Within migration and globalization the concept of ethnic identity, religious identity and belonging have come to play a significant role in both immigrants? lives and as well in social context. Sweden, as a multicultural society has been dealing with different ethnic groups of immigrants and the way these minority groups perceive themselves to be and how they are perceived by others in the society has also come to be of high importance. By migrating people also change their position. They often occupy inferior positions in the society when they settle down in the new country.

This study?s aim was to explore how the social media Twitter is used by Swedish political leaders and how they manage the relationship between having both private and public conversations in a new public sphere, the social sphere. In Sweden, studies in this area are yet to grow. We achieved our aim by responding to our three questions at the issue: What kind of content is published in each of the politicians Twitter stream? Are the politicians private or public persons on Twitter? Are the politicians using Twitters interactive functions? We conducted our analysis by performing a quantitative content analysis.

Uppsatsens huvudsakliga syfte är att utforska och kartlägga begreppet gamification. Syftet operationaliseras i tre frågeställningar. Vad finns det för likheter respektive skillnader i synen på Gamification mellan ett antal yrkesverksamma inom Gamification? Hur ser yrkesverksamma med olika bakgrunder inom psykologi, pedagogik och marknadsföring på framtiden för Gamification och dess användningsområde? Vilka för- och nackdelar kan finnas med Gamification? Uppsatsen teoretiska utgångspunkter omfattar de psykologiska krafterna bakom spel som flow och motivation, teorier om det praktiska användandet av gamification och teorier om Generation Y. För att samla empiri har kvalitativ metod använts i form av semistrukturerade explorativa intervjuer där yrkesverksamma inom gamification har intervjuats.

Title: Identity management on Facebook: a qualitative study in approaches to personal identity between two different age groups on the most public stage of our time (Identitetshantering på Facebook: En kvalitativ studie om förhållningssättet till den egna identiteten hos två olika åldersgrupper på vår tids mest offentliga scen).Number of pages: 43.Author: Isabelle Kåge.Tutor: Amelie Hössjer.Course: Media and Communication Studies C.Period: Fall Semester 2010.University: Division of Media and Communication, Department of Information Science, Uppsala University.Purpose/Aim: To identify differences in attitudes towards and management of personal identity onFacebook within two different age groups.Material/Method: Personal interviews, literature, electronic sources, Internet sources.Main results: Those in the younger age group present themselves differently depending on the person or persons with whom they are communicating. Those in the older age group however, present themselves in a more consequent matter based upon the visibility their actions have to all their friends on Facebook as a whole. The definitions of certain elements on Facebook, such as what constitutes private information or anexcess of photo-tags, differ between the two age groups. Comments and feedback differ in importance and effect between the two age groups. Those in the younger age group are more likely to modify their attitudes towards their identities based upon the functions of Facebook.
