Är det möjligt att förlita sig på att de smarta mobiler som utnyttjar operativsystem bestående av Android, iOS eller Windows Phone, håller informationen skyddad från spridning om enheten blir stulen eller förläggs? Det här arbetet innefattar undersökandet av medföljande krypteringar för skydd av filer och dess innehåll på ett antal smarta mobiler som kör något av operativsystemen Android, iOS eller Windows Phone.En undersökning där resultatet blev att samtliga testade system är tämligen säkra utifall rätt förutsättningar finns tillhands, samt att mest varaktigast krypteringsalgoritmer innehas av Windows Phone i form av algoritmerna HMACSHA1 och HMACSHA256..

The aim of our bachelor thesis was to study how the personnel incharge of the mobile websites at two University Libraries and thestudents at those Universities viewed the mobile websites, and iftheir views in any way differed.Our research questions were:Why have the examined Libraries chosen to offer mobilewebsites?How do the students at the examined Universities experience anduse respective mobile website?Are there differences between the staff?s intentions with themobile websites and how they are used and experienced by thestudents, and how could they be explained?Semistructured interviews were conducted with six staff membersresponsible for the mobile websites and eleven students that hadexperience in using these. The theoretical framework for thisthesis consists of Klasson?s three models for University Librarianspersonas, and the parts of Rogers theory about diffusion ofinnovations that concerns the attributes of innovations and thecommunication channels.The result of the study indicates that there are some differencesabout how the students use and experience the mobile websitesand the staffs intentions for them. The students required contentwhich the staff had discarded.

While the technological infrastructure that enables collaboration between municipalities, counties and private health care providers improves, so does the need for health-care providers to gain access to the right patient journal at the right time. For doctors, nurses and other health-care organization employees this goal is achieved by NPÖ, National Patient Summary. NPÖ effectively enables health-care records to be shared across organizational boundaries. This thesis is based on a demand by a mobile application that can give district nurses access to health-care records wherever they are.This thesis describes the development of a prototype of a mobile application aimed for NPÖ. This includes investigating a suitable mobile platform, investigating available card readers for reading electronic identification from SITHS cards and the ability to connect to external services such as NPÖ.

This study deals with teachers ideas about the physical environment of a mobile preschool and how it affects children?s learning. The essay describes how the preschool bus is decorated and how a normal day works in the mobile bus. The survey was based on the following questions:Are there disadvantages and advantages in terms of physical environment in the mobile preschool from an educator based perspective?What are the teacher?s thoughts about the impact on children?s learning in terms of the physical environment on the bus?Summary: To answer my questions I have participated in activities during the day and I have used the interviews to find out the teachers thoughts.

In today's society there is a significant focus on energy efficiency. Despite this, people leave lamps, televisions and computer screens etc. powered on unnecessarily. The goal of this project is to build a simple prototype for home automation where a user, via an application on a Mobile phone, can switch on and off the power of an electrical products in the home and as well as being able to check whether such products are switched on or off. The prototype will also collect data on power consumption for these electrical products.

The most common method for identifying merchandise in the commerce is by barcodes. Symbian OS is an advanced operating system aimed at cell phones and the most commonly used in smart phones. Opportunities to a full range of new services are given through barcode recognition in a Symbian OS based device. Therefore the purpose of this degree project was to create an application which would contribute to a future solution aimed at shopping where the cell phone constitutes a reader of items? identification numbers.

The use of mobile devices has during the last years expanded and on the market you can see a huge amount of applications. The development of mobile applications differs from traditional systems development since mobility infers that mobile applications can be used in different technological and social contexts. Although previous research has recognized that mobility can present mobile application developers with certain challenges, empirical studies of how problems arise and how they can be handled has thus far been limited. In this study we focused on the requirements engineering process from a development view with the purpose of finding challenges emerging in the development process. The study is based on a qualitative case study that employed semi-structured interviews with both project managers and system developers active in the requirements process.

This report describes the implementation of expense reporting in a mobile web application. Two different types of expenses could be reported: remuneration and time deviations. In addition to the creation of new expenses, existing expenses should be able to be edited or deleted. The implementation would be designed in such a way that it prevents the user from making data entry errors in an intuitive way.  The bachelor?s thesis was performed for Flex Datasystem AB in their mobile web application, Flex WebApp. Due to delimitations made during the project only functionality for the expense-type remuneration was implemented..

Purpose/Aim: In the information and communication technology society (ICT) we live in today it is easy to feel that we are constantly expected to be available. The daily contact with the Internet and the use of cell phones has changed our way to communicate. With this in mind in combination with the increased stress among young adults my aim is to investigate how young adults, aged 23-26 years, experience to be constantly connected and available through the Internet and the cell phone. What are their opinions, attitudes and feelings about what this entails in their lives?Material/Method: The essay is based on four focus group interviews with sixteen students from Uppsala University aged 23-26, two groups consisting of women and two groups consisting of men.

This assignment has been performed at location and commissioned by AttenditAB in Jönköping. The task has been to develop a client/server system to accessdata stored in SQL databases where the client application is developed to run onregular cellular telephones. The importance has been to develop as reliable mobilecommunication as possible. The functionality that is demanded upon the mobilecommunication is:? Secured for future versions? Interoperability? Data should not be bugged, modified or disappearunnoticed? Resource efficientWe have achieved these demands by developing our own protocol that is on top ofthe TCP protocol.

The use of mobile devices has increased dramatically in recent years and the development of newtechnologies has made it difficult for developers to know what screen size and device the visitor isusing. This has resulted in the fact that today there is a problem with the interface for web pages onmobile devices. They are not adapted to the flexibility required for the interfaces to be recognizedon various mobile devices. Instead of developing two separate web pages, where one is designed formobile devices and one for desktop and keep them both continously updated, responsive webdesign simplifies the work process. Responsive web design is a flexible and dynamic interface thatadapts to mobile device and screen sizes.

The usage of location in mobile applications is becoming more explored as a field, but the ability to implement location-specific data has often been limited and the applications mainly focusing on having information location liked. This thesis aims to explore how to make a mobile application that lets users share and take part of each other?s memories. As well as finding an appropriate balance between location based and location linked messaging..

Projektet som denna rapport beskriver hade som målsättning att utveckla två applikationer på beställning av företaget Teknikhuset Umeå. En av dessa applikationer skulle vara till Windows 8 plattformen och den andra till Windows Phone 8 plattformen. Applikationernas syfte var att ge användaren information om högtider från kyrkoåret med hjälp av information hämtad från Svenska Kyrkans kalender API (se Henrik Johanssons rapport).Denna rapport beskriver utformandet av användargrässnitten till dessa två plattformar. Syftet med rapporten är att undersöka hur utvecklaren kan bygga ett optimalt användargränssnitt för respektive plattform och samtidigt undersöka om det finns likheter i dessa två utvecklingsprocesser. Om likheter i utvecklingsprocessen observeras så kommer dessa dokumenteras för att i framtiden kunna effektivisera utvecklingsprocessen för applikationer avsedda för dessa två plattformar.
