The aim of the work is to create an application for a smart watch, which will allow you to measure races and trainings, or create localization data for this activity. The application is implemented for mobile devices with the Android and iOS operating systems. The Wear OS operating system is supported for smart watches. The thesis describes the theory of programming for mobile operating systems and programming for the operating system Wear OS. The practical part describes the design, implementation and testing. For the implementation of the mobile application as well as for the smart watch application I decided to choose Flutter framework and programming language Dart. The resulting application allow users to measure races and workouts.

This master’s thesis deals with architecture of the IMS network and analysis of the affects when loading the network. Architecture of IMS is a network of new generation. It convergates fixed and mobile networks and it enables quick installation of new multimedia services. The first chapter is focused on the description of the IMS architecture, its components and their function. The next chapter is devoted to the main protocols in the IMS system. It is mainly about signalization protocol SIP. The third chapter focuses on the queueing theory. For simulation of the IMS network, Open IMS Core enviroment was chosen, described in the fourth chapter. Next chapter is dedicated to the IMS Bench SIPp tool used for generating and testing the SIP protocol with focus on the IMS. The final chapter dedicates to the realization of an IMS network. The begining of this chapter deals with the description of individual conections generated by the IMS Bench SIPp tool. In the next part load tests focused on the created IMS network are created and analyzed in detail. The end of the chapter describes the implementation of the real finished call between devices and the Android operating system.

The aim of this Master's thesis is designing and developing Android application for automatic number plate recognition with external database lookup. In the introduction we discuss possibilities of number plate recognition in general. Android platform fundamentals, necessary developer tools and multi-platform image processing library OpenCV are described in the second section. In the third section different database types and synchronization methods are introduced. In the fourth section we describe basics of image processing and different algorithms necessary for recognition. Application requirements, involving scene and hardware requirements are defined in the fifth section. In the sixth section application development and algorithm implementation is described. In the seventh section we evalute the results of the detection. In the last section results are summarized and goals are set for further improvement.

The aim of the work is to design an application for mobile devices with the Android operating system. This application allows image capturing with a camera and image processing with the support of the OpenCV library. The purpose of this application is automatic value recognition of the analog electrometer. The text contains a description of the analog electrometers. The following is characteristic of Android operating system, and this part is directly connected to a draft of the application itself. Next part contains the image processing algorithms, testing and implementation into Android application.

The proposed master thesis deals with design and implementation of application for editing of raster graphics for Android operating system. First of all, an overview of available software is shown. Based upon this overview, requirements for implemented software are formulated. Required theoretical knowledge providing foundation for implemented functions is summarized in the next chapter. Further Android operating system is introduced with respect to its deployment and other specific characteristics, which have direct impact on application development. The following part describes implemented application from end user perspective. User interface is described here together with application features. The last chapter is focused on implementation of created software – separation to single modules and class responsibilities. Appendices contain examples of application usage.

The aim of this thesis is design and implementation of Android application which will serve as real-time translator from one language to another, including several world languages and Czech. The text obtained from image is translated and replaces the original one with keeping its visual look as much as possible. The reader gradually gets familiar with getting text from images, text translation, displaying text on mobile device and Android OS implementation. In conclusion, the experiments with multiple input images and comparison of existings applications have been done.

This thesis brings application for mobile devices placed in cars. It is used for drivers for enhancing orientation and driving clarity. It is based on communication between roadside units and devices in vehicle. Application offers graphical visualization of intersection states and traffic lights.   Created solution provides graphical visualization of traffic data designated for system Android.   Main benefit is for C2X developers who test correctness of information, which were inserted to physical devices near supported intersections.

This thesis addresses video streaming from smartphone to smartwatch. The main goal of the thesis is to find a way how to handle the limited hardware features of the watch and make video streaming as fast and smooth as possible. A part of this work is focused on implementation of client-server application, which streams video from Android device to Tizen smartwatch over Bluetooth channel.

Sedan den nya personuppgiftslagen, GDPR, trädde i kraft har större krav ställts på organisationer gällande hantering av personlig data. När processer inom en organisation ska digitaliseras, ställs högre krav på säkerheten av data. Ett bilföretag i Karlstad fick som krav från en av sina leverantörer att digitalisera sin provkörningsprocess, som tidigare var pappersbunden. Genom att automatisera processen och lagringen av data säkerställs det att detta hanteras korrekt. En lösning var att skapa en mobil applikation som skannar in körkort och sparar kunddata i en databas. Applikationen utvecklades för att uppfylla företagets krav samt de regelverk som GDPR innebär för digitala lösningar som hanterar känslig persondata. Applikationen skapades med hjälp av Xamarin i Visual Studio med fokus på Android applikationer. Data sparas i en molndatabas hos Microsoft Azure. I rapporten presenteras applikationens metoder och hur de samspelar för att ge den önskade funktionaliteten. I resultatet beskrivs också vilka krav som har uppfyllts. / Since the new General Data Protection Regulation (GDPR) came into force, greater demands have been placed on organizations regarding the handling of personal data. When digitalizing processes within an organization, higher demands are placed on data security. A car company in Karlstad was required by one of its suppliers to digitalize their test driving process, which was previously paper bound. By automating the process and storing the data, it is ensured that this is handled correctly. One solution was to create a mobile application that scans driving licenses and saves customer data in a database. The application was developed to meet the company’s requirements as well as the regulations that GDPR imposes on digital solutions that handle sensitive personal data. The application was created using Xamarin in Visual Studio focusing on Android applications. Data is stored in a cloud database at Microsoft Azure. The report presents the application’s methods and how they interact to provide the desired functionality. The result also describes what requirements have been met

The diploma thesis focuses on the issue of movement and interaction in virtual reality and then shows the design and concrete example of the application.
