The open mobile phone platform
Malinčík, Ondrej ; Šteffan, Pavel (referee) ; Macháň, Ladislav (advisor)
The aim of this work is construction of mobile phone which can be build using com- ponents that are widely available. The concept allows control of mobile communication in GSM network on AT commands level. Energy saving is emphasised and alternative power source using solar cell is examined. Manufacturing data and docummentation is available for user.

Communication of a Measuring Device with a Computer – Laboratory Experiments
Cigánek, Jan ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
This project deals with the programme for automated measurement. Project describes main theory advices and possibilities of building programme with language C++. It shows complication in communication of PC with measurement devices and it describes programme commands. This work includes programme, solution, structure with examples of the algorithm and source code. The designed control programme has been applied for automated measurement of frequency characteristics of low-pass and high-pass filters with the analogue multiplier AD 633 using the programmable DC power supply Agilent E3631A, the digital multimeter Agilent 34411A or digital storage oscilloscope Tektronix TDS 1012 and generator Agilent 33220A.

Design and making of low-frequency power amplifier in class AB
Dušek, Martin ; Kratochvíl, Tomáš (referee) ; Brančík, Lubomír (advisor)
In this bachelor thesis I am occupied with low frequency amplifiers, theirs important parameters, classes and with integrations end-level. Next I am occupied with miscellaneous types of preamplifiers and additional circuits. There are simulated schemes of corrective preamplifier, protections scheme and high power amplifier in PSpice software in this thesis. These schemes and next additional modules are connected with DPS. This thesis contains result of measurement and photo functional sample.

Mobile application for remote server management
Kolář, Jakub ; Pecinovský, Rudolf (advisor) ; Rais, Aziz (referee)
Thesis deals with remote servers specifically those for the Minecraft. These servers are divided into groups. The work examines the possibility of remote access to these servers on network protocols level, which are described briefly, and also at the level of the game itself. Describes the game options that can be influenced via remote management. Then analyzes the applications that are intended for this remote access, and identifies problems associated with them. Based on the issues that implied from this analysis, application that solves these problems is designed. The first chapter contains a brief description of the network protocols that can be used to remotely manage servers for the Minecraft and identifies the most appropriate protocol. The next chapter describes the Minecraft, and specifically those of its regions which can be influenced via remote management. The next chapter analyzes the applications that can be used to remotely manage Minecraft servers and based on the problems that this analysis identifies, an application that solves these problems is designed. The designed application is then implemented. The last part contains user documentation of created application.
