Java applications - theory and practice
Mareček, Miroslav ; Halbich, Čestmír (advisor) ; Radomír, Radomír (referee)
The aim of this thesis is to characterize the foundational aspects of the Java programming language and the development of applications with it. As an exemplary application on which to demonstrate the findings, we will use Nand2Tetris playground, a simple education application, some of which's aspects will be analyzed within the thesis. The aim of the Nand2Tetris Playground project will be to propose and implement a graphical user interface for the first part of the Nand2Tetris computer architecture course, created by Noam Nisan, Ph.D. and Simon Schocken, Ph.D. In this part of the course, the student is tasked with assemblig all the basic boolean logic gates and several other basic parts using only NAND gates. Software for this part already exists, but can be user unfriendly, especially for a student not well versed in computer science. This is why the GUI that will be proposed and implemented will make the course more accessible even to students not very proficient in the area.

OS Google Chrome - theory and practice
Plecháč, David ; Halbich, Čestmír (advisor) ; Tomáš, Tomáš (referee)
The thesis is focused on the characteristics of the key features of the operating system Google Chrome OS and on the evaluation of deployment of this operating system in practise. The theoretical part describes the purpose and philosophy of the commercial operating system Google Chrome OS and its relation with Chrome web browser. The connection with open-source projects Chromium and Chromium OS is explained. Details of application development and deployment options, in the form of virtualization and domain administration, are analysed. The practical part applies theoretical knowledge from the development of applications for Chrome OS to create thin client application for remote control of hardware sensor over the internet. This sensor is designed and built on the platform Arduino. The sensor measures the temperature and humidity of the ambient air and remote controls high-voltage switching relays. Communication over TCP/IP uses modern MQTT protocol, for which the server is configured with MQTT Broker Mosquitto.
The next section demonstrates the procedure for building a customized build of Chromium OS from the publicly provided Google source codes. Based on the evaluation of the acquired theoretical and practical knowledge, I assess the possibility of deploying the Chrome OS in private and commercial areas.
