Användandet av internet i mobiltelefonen har ökat drastiskt de senaste åren och detta fenomen innebär att människor har tillgång till internet i större utsträckning än förut. De svenska bankerna har tagit tillvara på denna trend genom att utveckla mobila bankapplikationer där de erbjuder sina kunder möjligheten att utföra bankärenden med hjälp av mobiltelefonen. Även om fördelarna med denna tillgång är många, finns det ändå vissa nackdelar. Den mest omtalade nackdelen gällande bankers mobilapplikationer är bristande säkerhet som kan medföra integritetsrisker. Utifrån personliga erfarenheter uppstod funderingar kring området användbarhet och säkerhet för bankers mobilapplikationer och dessa funderingar ligger till grund för vårt arbete. Syftet är att undersöka användbarhet och säkerhet för identifikationsmetoder samt användbarhet för hantering av transaktioner i internetbankers mobilapplikationer ur ett användarperspektiv. För att undersöka dessa områden går vi igenom och tar hjälp av teorier och tidigare forskning och dessutom tillämpar vi ett antal metoder. I slutsatsen har vi utifrån resultaten från vår studie sammanställt riktlinjer för hur en banks mobilapplikation bör utformas för att uppfylla användarnas behov och önskemål. / The use of mobile Internet has increased dramatically in recent years and this phenomenon means that people have access to the Internet to a greater extent than before. Swedish banks have been taking advantage of this trend by developing mobile banking applications where they offer their customers the ability to perform banking transactions using their mobile phone. Although the benefits of this increased access are many, there are still some drawbacks. The most talked about drawback regarding banks’ mobile applications is the lack of security that could lead to privacy risks. Based on personal experience, we had concerns about the area usability and security for mobile banking applications and these thoughts are the basis of our work. Our aim is to examine usability and security of identification methods and the usability of processing transactions in the mobile bank application from a user perspective. To explore these areas we will review and get support from theories and previous research and in addition, we apply a number of methods. In conclusion, we’ve compiled guidelines based on the results of our study of how a bank’s mobile application should be designed to meet user needs and preferences.

Nucleic acids are fundamental molecules of living organisms functioning essentially as the molecular information carriers of life. From how an organism is built to how it responds to external conditions, all of it, can be found in the form of nucleic acid sequences inside every single cell of every life form on earth. Therefore, accessing these sequences provides key information regarding the molecular identity and functional state of any living organism, this is very useful for areas like biomedicine, where accessing and understanding these molecular signatures is the key to develop strategies to understand, treat and diagnose diseases. Decades of research and technological advancements have led to the development of a number of molecular tools and engineering technologies that allow accessing the information contained in the nucleic acids. This thesis provides a general overview of the tools and technologies available for nucleic acid analysis, and proposes an illustrative concept on how molecular tools and emergent technologies can be combined in a modular fashion to design methods for addressing different biomedical questions. The studies included in this thesis, are focused on the particular use of the molecular tools named: padlock and selector probes, rolling circle amplification, and fluorescence detection of single molecules in combination with microfluidics and portable microscopy. By using this combination, it became possible to design and demonstrate novel approaches for integrated nucleic acid analysis, inexpensive digital quantification, mobile-phone based diagnostics and the description of viral infections. These studies represent a step forward towards the adoption of the selected group of tools and technologies, for the design and building of methods that can be used as powerful alternatives to conventional tools used in molecular diagnostics and virology. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 1: Manuscript.</p>

Anonymous Call Detail Records (CDR’s) from mobile phone towers provide a unique opportunity to aggregate individual location data to overall human mobility patterns. Flowminder uses this data to improve the welfare of low- and middle-income countries. The movement patterns are studied through key measurements of mobility. This thesis seeks to evaluate the estimates of key measurements obtained with mobile phone towers through simulation of continuous human movement on a linear network. Simulation is made with an agent based approach. Spatial point processes are used to distribute continuous start points of the agents on the linear network. The start point is then equipped with a mark, a path with an end point dependent on the start point. A path from the start point to the end point of an agent is modeled with a Markov Decision Process. The simulated human movement can then be captured with different types of mobile phone tower distributions realized from spatial point processes. The thesis will initially consider homogeneous Poisson and Simple Sequential Inhibition (SSI) processes on a plane and then introduce local clusters (heterogeneity) with Matérn Cluster and SSI processes. The goal of the thesis is to investigate the effects of change in mobile phone tower distribution and call frequency on the estimates of key measurements of mobility. The effects of call frequency are unclear and invite more detailed study. The results suggest that a decrease in the total number of towers generally worsens the estimates and that introducing local clusters also has a negative effect on the estimates. The presented methodology provides a flexible and new way to model continuous human movement along a linear network.

Präsenzbewertung im Kommunikationsraum der Telefonie ist ein zunehmend wichtiges Gebiet der Forschung. Ziel der Dissertation ist es, sich dem natürlichen Kommunikationsraum der verbalen und nonverbalen Kommunikation anzunähern. Im Kommunikationsraum Telefonie existieren noch keine Verfahren, die unterschiedliche Dringlichkeiten von Anrufen wiedergeben. Momentan ist die Signalart ausschließlich davon abhängig, wie der Angerufene sein Mobiltelefon eingestellt hat. In der Arbeit wurde ein Verfahren entwickelt, das unmittelbar vor der Signalisierung eines Anrufes die Signalart abhängig vom Kontext des Angerufenen individuell ermittelt und automatisch einstellt. Dabei werden Algorithmen aus dem Bereich der KI verwendet. Mit Hilfe von Lernalgorithmen werden die Ergebnisse der Präsenzbewertung kontinuierlich verbessert. Im Rahmen eines Experimentes konnten Präzisionen bei sechs verschiedenen Signalarten von bis zu 73 % erreicht werden. Dieses Verfahren ermöglicht eine deutliche Annäherung an den natürlichen Kommunikationsraum.

This master thesis is dedicated to comparison of classical book and electronic book reader and it examines the advantages and disadvantages of both formats for recipients. In this work the importance of the printing press for society will be described and also the reactions which were induced by its invention. Following chapters will be dedicated to the book itself. Most importatntly what "makes the book being the book" and what are its strength and weeknesses and why it is still popular. As a contrast to this phenomenon the massive increase in popularity of electronic book - especially e-readers in pocket readers, on the internet and in the smartphones which become potential competition for books. The goal of this work is to compare the printed version which is represented by paper book and electronic version which is represented by e- books. Comparison will be based on the description of the specifics of both information tools from technological aspect as well as from the different text perception and the enjoyment from the reading itself. At the end there is an attempt to predicate the possible development in the future - is book culture facing a crisis or will it hold its position in following years?

Introduktion – Millennials, är den första generation som har växt med teknologi nära tillhands. För dem har mobilen fått bli en integrerad del av deras liv, vilket har påverkat hur dem som konsumenter interagerar med en butik och dess miljö. På många sätt har mobilen blivit en distraktion för dem när de är i butiken, men på vissa sätt så kan den också vara en hjälp för dem, speciellt i komplexa köp. Detaljhandlare har däremot fram tills nu sett mobilen som ett problem då den leder till att konsumenten ignorerar det som finns i butiken, men eftersom mobilen har betydande roll i konsumenternas liv bör de istället byta fokus. De måste istället hitta sätt att dra nytta av mobilanvändningen, både för deras egen fördel och förkonsumenternas. Syfte och metod – Studiens syfte var därmed att få en djupare förståelse för hur detaljhandlare kan hitta värde i mobilanvändandet för millennials i komplexa köp. Vidare, syftade den till att kunna ge teoretiska bidrag kring konsumentens värdeskapande, genom att sammanfläta mobilanvändandet med butiksmiljön. Studien gjordes som en kvalitativ fallstudie på IKEA genom användningen av två metoder. 47 respondenter tillfrågades att göra tre uppgifter på köksavdelning medans de bar eye trackingglasögon som filmade vad de gjorde. Efter det, fick de göra en komplimenterande semistrukturerad intervju, och alla data analyserades sedan med hjälp av en tematisk analys. Resultat och slutsatser – Resultatet visar att millennials använder sin mobil för att hjälpa dem navigera sig i butiken, hitta information, och viktigast, för att ta foton på information och inspiration. Däremot, även ifall konsumenten ser mobilen som ett värdefullt verktyg, visar också resultatet att trots det fortfarande är viktigt med personlig service i komplexa köp. Till sist, finns det också indikationer på att serviceerbjudande i butiken måste anpassas för att återge mer tydlig och relevant information, samt att skyltarna behöver skapa interaktioner mellan konsumenterna och mobilen, till exempel genom användningen av QR-koder. Teoretiskt, bidrar denna studie både genom att ge ytterligare stöd till tidigare studier och genom att bidra med nya insikter kring värdeskapande i serviceerbjudandet. / Introduction – The digital native generation, millennials, is the first generation to grow up with technology close at hand. For them the mobile phone is an integrated part of their lives, which has an impact on how they as consumers interact with the retail environment. In many ways the mobile phone can be a distraction for them in store, but in some ways, it can also be a help for them, especially in high involvement purchases. Retailers has up until now found the mobile phone to be a problem since it can make the consumers ignore the retail landscape. However, since the prominent role the mobile phone has in the consumers life, there need to be a switch in focus, and retailers needs to utilise it, both for their own and the consumers benefit. Purpose and methodology - The aim of this study was therefore to get a deeper understanding of how retailers can find value in mobile phone use for the millennial consumer in high involvement purchases. In addition, it aimed to make theoretical contributions to consumer value creation, by incorporating the mobile phone usage into the retail environment. The study was done using a qualitative multiple research method in a single case study on IKEA. 47 millennials respondents were asked to perform three tasks in the kitchen department while wearing eye tracking glasses to record their actions. Thereafter, a complementary semistructured interview was performed, and the data was later analysed using thematic analysis. Result and conclusion – The results show that the millennial consumers use their mobile phone to help them navigate the store, find information, but most importantly to take photos for information and inspirational purposes. However, even though many consumers found the mobile phone as a valuable tool, in high involvement purchases personalised service is still highly valued. Finally, the result indicated the services cape needs to be adapted with clearer and more relevant information as well as signs to create interactions with the consumer and the mobile phones such as QR codes. Theoretically, this study both supports the results from previous studies as well as contributes with new insights to the theoretical field of value in service.
