This thesis aims to improve the user's orientation in terrain using his smartphone and augmented reality. By combining these two elements and cost-free OpenStreetMap database of geographic data, is possible to show nearby map features from the maps or show additional information about nearby objects. The resulting technology is used in implemented iOS application called Water Radar. This application displays nearby water streams (or other water objects) relative to the GPS position of the user. The application also uses Google Elevation API, in order to enable displayed water streams to follow the landscape.

This thesis is focused on Augementied reality in mobile applications. The aim of the thesis is to create mobile application that provides its users with the view of the past of selected buildings. At the beginning of the thesis, the reader is presented with various methods and technologies for working with augmented reality. Based on the theorie obtained in first chapters, a mobile application was designed and implemented. The final mobile application allows its users to view historical buildings.

The thesis deals with the development of mobile applications, current mobile operating systems and focuses on iOS programming. It also describes the main function of SAP ERP system, SAP ME system and their integration with SAP MII. It also mentions the way to communicate with SAP MII using web services. Finally, there is an analysis of mobile application requirements, implementation and testing. That application will collect and display KPI from work centers and, in the event of a decrease of any KPI, generate notifications for selected people.

Target of this thesis is creation of mobile application enabling easy sharing of user's location in a group. Thesis includes analysis of needs of users, GUI and options of including new members of a group. Application is available for both major mobile platforms, iOS and Android. For that reason it was developed with tool Flutter providing multiplatform applications development. Necessary part of the application is web server written in language PHP and framework Yii2.

The growing trend in the share of mobile application use results in higher user expectations for applications. Much more emphasis is placed on both the appearance and ease of use of the applications themselves. This work examines this issue, analyses the market and then uses its findings. From these findings, a proposal for a new application is created, which will be used to promote the newly established company. The work also includes economic and non-economic aspects associated with the development of the application.

This thesis deals with the design and implementation of mobile application, which will be designed for iOS and Android operating systems by using tools for mobile application development. For implementation was chosen tool Xamarin, which is is adapted for software development of hybrid mobile application

The thesis deals with design and implementation of prototype of mobile application for Android and iOS operating systems. Framework React Native was chosen for realization because it allows multiplatform development. Application focuses on data visualization from sales of handmade products on Fler web portal.

Tématem této diplomové práce (dále jen DP) je návrh rozsáhlých podnikových sítí podle doporučení stanovených společností Cisco. Dále je realizována simulace navržené topologie prostřednictvím programů s otevřeným zdrojovým kódem a dohled nad sítí prostřednictvím programu Nagios. Úvodní část obsahuje stručné seznámení se základním rozdělením sítě do jednotlivých funkčních bloků. Druhá část se zabývá popisem jednotlivých funkčních bloků a jejich rolí v rámci celé síťové topologie. Bloky jsou dále rozděleny na jednotlivá zařízení a jsou popsány služby, které tato zařízení musí poskytovat. Třetí část DP se snaží zmapovat základní požadavky na služby, které jsou kladeny na dnešní síťové infrastruktury. Hlavní důraz je kladen na dostupnost všech nabízených služeb sítě. Jsou vyjmenovány jednotlivé protokoly druhé až třetí vrstvy OSI modelu, které zabezpečují stálou dostupnost sítě v případě selhání aktivních prvků. Čtvrtá část DP se věnuje popisu návrhu síťové topologie WAN. Pátá část obsahuje popis bezpečnostních rizik, která ohrožují dostupnost sítě, tak i popis útoků, které mají za cíl krádež identity uživatele. V šesté části DP jsou popsány programové nástroje pro zprávu sítí (Nagios, Cisco Security Device Manager) a programy, které simulují Cisco přepínače, směrovače (Dynamips & Dynagen, GNS3) a Cisco PIX firewall (PEMU). Sedmá kapitola se zabývá konkrétním návrhem rozsáhlé sítě s použitím principů, které byly zmíněny v předcházejících kapitolách. Navržená infrastruktura je dále realizována pomocí simulačních programů a tato virtuální síť dovoluje demonstrovat nastavení a chování všech popsaných protokolů a zařízení. V závěrečném shrnutí je nejdůležitější poznatek, že návrh a konfigurace rozsáhlé sítě a její realizace ve virtuálním prostředí je funkční a použitelná pro pokusné účely i pro studijní účely.

The main aim of the master thesis was to create an application for backbone network configuration management. The priority of the application was to be effective and easy to take. Program has to be able to communicate with network devices by remote control and to download and upload configuration files. The program has enable also availability verification for remote control. For this purpose the ICMP protocol was used. The remote control is provided by telnet protocol and the protocol TFTP has been chosen for file tranfers providing. The application is a multithreading application based on the Java programming language. The Java graphic library Swing was used for GUI creation. The application supports file versioning, the configuration of the program can be saved as a text file, which can be easy changed by user. The program and its features are described in the second part of this thesis. The first part deals with theoretical facts about the IP networks and remote control of the Cisco backbone network devices.

The aim of this master’s thesis is design and implementation local chat system for mobile devices and smartphones. System contains main server, witch covers communication with application for smartphones and web server, witch covers communications with browsers and presentation application, witch goal is to presenting chat to area. Smartphone ap- plication is crated for Android, iOS, Windows Mobile and Symbian operating systems. Wifi network is used for communication and message sending and signal coverage area defines local chat. Messages are shown dynamically and it’s possible send them as user status to Facebook social network.
