Äldre och den nya världen : En kvalitativ innehållsanalys av medieanvändande hos den äldre generationen
AbstractTitle: The old generation and the New World - A qualitative content analysis of media usage of the older generationKeywords:Digital natives, digital immigrants, diffusion of innovation, content analysisThis study has its focus on how the older generation looks at today's media society and the use of today's media. Through a method of qualitative content analysis based on questionnaires, the aim is to examine what the older generation thinks about today's media, how they use them, and whether there are differences in groups according to age and previous work.The study selected theories bases on Marc Prenskys idea of ??digital natives, digital immigrants and Everett M Rogers book on "Diffusion of Innovation". These theories take up the difference on digital natives and digital immigrants and the spread of new technological ideas takes place through communication over different channels in time among causes people in a social system.The result of the study shows that many older people are good at making use of today's media, but also that many may feel alienation of today's media society. Development has proceeded rapidly in recent years and for the older generation it's sometimes hard to keep up.The conclusion of the study is that the older generation may need more help to discover how today's media can facilitate everyday life and enrich it with more communication despite the fact that it takes place through a screen..

Detektering av sprickor i vägytor med hjälp av Datorseende
This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.
Klädbutikens möjligheter att stärka sitt varumärke och sin image : med koppling till människans sinnen
I denna uppsats har vi tydligt urskiljt olika inslag och delar som är viktiga att ta hänsyn till vad gäller att stärka klädbutikers varumärke och image. Genom dem så har vi utvecklat en egen modell som förklarar hur en klädbutik kan bygga upp och stärka sitt varumärke och sin image. Vi har delat upp modellen i två steg, det första steget tar upp de delar och inslag som är fundamentala och den andra delen är en påbyggnadsdel, om klädesbutiken vill förstärka sitt varumärke och sin image ytterligare. Det första steget innefattar hur inslag och aktiviteter från de två sinnena, ljud och syn påverkar klädbutiken. I denna del speglas dessutom vilken roll personalens attityder och bemötande har för kundens upplevelse av butiken.
Cross-language information retrieval : en studie av lingvistiska problem och utvecklade översättningsmetoder för lösningar angående informationsåtervinning över språkliga gränser
Syftet med denna uppsats är att undersöka problem samt lösningar i relation till informationsåtervinning över språkliga gränser. Metoden som har använts i uppsatsen är studier av forskningsmaterial inom lingvistik samt främst den relativt nya forskningsdisciplinen Cross-Language Information Retrieval (CLIR). I uppsatsen hävdas att världens alla olikartade språk i dagsläget måste betraktas som ett angeläget problem för informationsvetenskapen, ty språkliga skillnader utgör ännu ett stort hinder för den internationella informationsåtervinning som tekniska framsteg, uppkomsten av Internet, digitala bibliotek, globalisering, samt stora politiska förändringar i ett flertal länder runtom i världen under de senaste åren tekniskt och teoretiskt sett har möjliggjort. I uppsatsens första del redogörs för några universellt erkända lingvistiska skillnader mellan olika språk ? i detta fall främst med exempel från europeiska språk ? och vanliga problem som dessa kan bidra till angående översättningar från ett språk till ett annat.

En studie av evalueringar av webbaserade söktjänsters återvinningseffektivitet
The aim of this thesis is to describe and critically investigate eight different evaluations of the retrieval effectiveness of webbased search engines. The questions to be answered in this investigation are: - What kind of relevance judgements have been used? - Which criteria have been used when judging the relevance of a document? - Which measures have been used? - How many queries have been used? - How were the queries constructed? - What document cut-off value has been used? - Has hypothes testing been applied? - What kind of webbased search engines have been included in the evaluations? The study showed that although the evaluations investigate the same phenomena, they are very different from each other in certain aspects. Generally the study showed that precision is the preferred measure in comparison to recall in the chosen evaluation even though all the included evaluations have constructed unique formulas for calculating precision. Some attempts to measure relative recall have been performed but they all suffer from different defects.

Spegel, spegel på väggen där, säg mig vem Team Sportia är : En marknadsanalys av Team Sportia Uppsala
Team Sportia Uppsala misstänker att de saknar en röd tråd i sin marknadskommunikation. Syftet med arbetet är att undersöka hur väl Team Sportia Uppsalas kundklubbsmedlemmars uppfattning om företagets image överensstämmer med identiteten företaget vill förmedla, med fokus på produktutbudet. Med hjälp av en personlig intervju med Fredrik Söderlund, vice VD Team Sportia Uppsala, en telefonundersökning av butikens kundklubbsmedlemmar samt en observation av butiken har identiteten samt imagen analyserats. Resultatet visar att företaget är inkonsekventa i förmedlingen av sin identitet och det har förekommit visst brus, vilket leder till att kundernas image inte överensstämmer helt med företagets identitet..
