Även om de flesta av oss i dagsläget vet att våra mobila enheter kan tappa sina nätverksanslutningar lite då och då har det mer eller mindre blivit en självklarhet att i alla lägen ändå kunna använda våra favoritapplikationer som vanligt. Denna rapport syftade till att hitta en lösning på problemet med nätverksberoende applikationer genom att implementera ett offline-läge som kringgick detta beroende i GreatRate, en iOS-applikation för kundundersökningar i butik. Med hjälp av en databas för att mellanlagra data under tillfällen då en duglig nätverksanslutning inte fanns tillgänglig samt synkronisering av nämnda data när anslutningen åter blivit funktionell förväntades problemet kringgås. Resultatet blev som väntat en applikation som gav användaren en förhöjd användarupplevelse helt oberoende av nätverksanslutningens status. Några av slutsatserna som drogs var dock att flera olika lösningar finns för detta problem och att problemet högst troligt har olika utseenden för olika applikationer.

This work deals with the development of cross-platform mobile applications and compares cross-platform development frameworks. First the mobile devices market is defined and its dominant platforms are described. The main objective is to compare the frameworks with defined criteria. The theoretical part analyzes the mobile market and defines the different types of mobile devices. Further, describes the various mobile platforms, including its architecture and de-velopment environment. Subsequently, the approaches to cross-platform development are described with their individual frameworks. In the practical part the selected frameworks are compared to defined criteria and subse-quently evaluated.

This thesis is focused on the technology of mobile devices. In the first part I analyse the technical parameters of the mobile device in detail, I mention each parameter and its importance, pitfalls and benefits. The second part is focused on mobile operating systems, especially iOS, Android and Windows Phone. The operating systems are analysed from the perspective of technological complexity, which builds on the analysis of the technology of mobile devices. The third part consists of future prediction. I describe hypothetical future development for both of previous parts of my survey. Approximate future development is mentioned in each chapter of of both first and second parts. The main benefit(contribution) of this work is the compact view on the issue of the technology of mobile devices. It helps reader to make a complex overview of the evolution and possibilities on the current mobile devices market.

This report aims to solve a problem for the   waxers in the Swedish National Cross-country Ski Team, which hereafter will   be referred to as the national team. The problem in hand is that currently,   the national team lacks a system for book-keeping of ski pairs and ski tests.   Also, the project intends to provide a tool for predicting the best ski pairs   in given conditions. The report describes cross-country skis and factors that   affect the performance of these skis. Moreover, this report presents the   testing procedure of the national team. The project provides a solution to   the problem in hand by developing a web service based on Django and Django   REST Framework and an iOS application to handle the user interaction. The app   was tested and approved by the waxers of the national team. To predict the   best performing skis in given conditions, the three Machine Learning   algorithms Support Vector Machine (SVM), Decision Tree, and Artificial Neural   Network (ANN) is implemented and evaluated. Experimental results indicate   that the ANN algorithm has better accuracy than the Decision Tree, and that   the SVM algorithms and that the SVM was performing slightly worse than the   other two, when applied on test data which is artificially generated based on   the experience of the national team. All three Machine Learning algorithms   perform better in terms of mean accuracy which is significantly higher   compared to the accuracy of a baseline algorithm. The report suggests that   the accuracy of the ANN algorithm is high enough to be useful for the   national team.

This thesis deals with development of multiplatform mobile applications. Part of the thesis is the design and implementation of a mobile application to facilitate the orientation of people in a large university environment. The application is designed for Android and iOS mobile operating systems and is implemented in the Ionic development environment. The application provides basic information about individual buildings of the university, displays buildings on the map and allows the user to navigate these buildings.

The aim of this thesis was to create two applications for people with learning difficulties. The first, i-CT Framwork, is also an executable application to be used with the target group mentioned above. As an executable application, i-CT Framework operates as a central tool for managing users, applications, and user restrictions. Development of Gesture Translator application presented another aim of the thesis: this application can translate sign language gestures for people with learning difficulties. Both applications are functioning on Android as well as iOS operating systems.

This thesis deals with the selection of an information system for Webnode, which offers on-line services to its customers. The company wants to expand its services and wants to give customers the ability to manage their websites through a mobile application. The thesis deals with the selection of an information system for creating a mobile application. The first chapter of the thesis explains the theoretical starting points that we will use in the practical part. The following chapter introduces the company and its vision, mission, and marketing mix and offers detailed analysis of the company, using a variety of methods. The third chapter deals with problem solving, information system selection and its implementation. At the end of the thesis, the benefits of the solution are summarized.

The diploma thesis deals with the universal mobile client-server application of Android and iOS devices solved in the native environment of the given operating systems. The work explores approaches to solving the problem in both environments. The application solution will display, store and process a variety of data sent to the server in a unified form as well as customize the look given the conditions addressed conditions and equipment. The aim of the thesis is to show and compare the native potential of the mobile device as well as to design a unified application of frequently asked issues - to view and access a large amount of stored data to the user.

Rephotography has been a popular research topic in the photography field for a long time. The purpose of rephotography itself is to repeatedly take photographs of the same scene at a different time. As a result, the sequence of rephotographs with the reference, often historical, the picture provides a compelling visualization of the evolution of the subject or capture its changes in time. However, the act of rephotography is difficult for the rephotographers as they have to cope with the ambiguous motions in six degrees of freedom and with the changes of the subject itself or its surrounding environment.        This thesis aims to create a mobile application that would help its users to capture a rephotograph more accurately and allow them to share the scenes amongst other users. The designed application uses available on-device sensors to navigate the user to the location and guide the user during the rephotography process to capture a precise rephotograph. Furthermore, the application contains user interface elements designed explicitly for rephotography. Moreover, the work describes topics about user interface design, iOS application development, and designing and deploying backend API for the mobile application.

This thesis concerns the development of a mobile application for the Apple iPhone plat- form for hot-air balloon pilots. The main functionality is to create up-to-date map of wind strength and direction for each flight level and navigation tools. Accompanying functions include pilot logbook management, flight recording and recall. A crucial aspect of this appli- cation is the GUI design, which meets the conditions in which the application will be used. The application will also be evaluated in test conditions during an actual balloon flight.
