The current possibilities of data networks
Pavelka, Jakub ; Vaněk, Jiří (advisor) ; Vladimír, Vladimír (referee)
The thesis is focused on mapping issues when creating data networks. Overview solved problems briefly introduces the history and classification networks. Continues characteristics of active and passive parts of the network where it connects certification, ending a general guide for network architects, which can be used to understand the theory of progress in the design and implementation of data networks with regard to its functionality and reliability. This section explaining how the proposal looks like a LAN, which is one of the most widespread types of networks, and most standards it is just related. The practical part is focused on the demonstration of a possible case design, including its economic parameters. The various alternatives are worked out with regard to the choice of materials offered different levels of quality and possible types of treatment for the future. The alternatives are as follows economically analyzed and evaluated.

Topological and Attribute Revision of Digital Maps
Dubec, Marek ; Sedláček, Svatopluk (referee) ; Ježek, Jiří (advisor)
The topic of this bachelor’s work is the attribute and topological revision of a digital map. In the work it have described geodetic software’s for attribute and topological revision of a digital information’s, with detailed described each function in each geodetic software. It’ll be created sample drawing of topological errors for testing each software. In the work are summary and evaluation results of the all tests

Computational analysis of column for horizontal boring centre
Fargač, Michal ; Vosynek, Petr (referee) ; Hadaš, Zdeněk (advisor)
The theoretical study of this thesis deals with different approaches that can be used to optimize the topology of various structures. Main attributes and principles which they are based on of individual methods are discussed. The first point of the practical part is to design the model for computational analysis of stand and other machining centre parts based on real machine TOS FU. Afterwards, the model is analyzed to determine the dynamic characteristic of the machine. Subsequently, several changes of the stand design are performed in order to improve the dynamic behavior. Eventually, new stand kernel is designed which aims to enhance these dynamic characteristic. This model is analyzed again and the results are compared with the original form of the machining centre.

Comparison of switching LED drivers
Káňa, Vojtěch ; Šotner, Roman (referee) ; Frýza, Tomáš (advisor)
This bachelor thesis describes switching LED drivers and their features. Is chosen and compared five integrated circuit, that one of them will be included in two different topologies. Especially in Buck-Boost and SEPIC configuration. Their characteristics and features will be simulated and designed in suitable software. Made equipment will be tested and compared their achievements properties. For a both of these drivers is required specified conditions as constant output current, input and output voltage.

Bluetooth Vibrating Ringer
Dočekal, David ; Dušek, Martin (referee) ; Povalač, Aleš (advisor)
This thesis is focused on the implementation of Bluetooth communication between a mobile phone and an external device. The first chapter focuses on Bluetooth technology in general. It describes the interface, device classes according to RF power, Bluetooth versions, security and pairing options. The second chapter of the Bachelor’s thesis deals with the Bluetooth module called HC-05. It describes the basic features and practical, module usage. It also shows the concept of the Bluetooth unit and describes the adjusting of certain parameters of the HC-05 module using the AT commands. The third chapter summarizes the deign and implementation of the device. Software and firmware development is overviewed in the fourth chapter. The testing and measurement results of the complete device are presented in the last part of this thesis.

Modelling Power Line Communication using Network Simulator-3
Pánek, Jiří ; Endrle, Pavel (referee) ; Mlýnek, Petr (advisor)
The semestral thesis deals with power line communication and its simulation in Network Simulator-3. The first part includes a general description of PLC, summarizes its division and the relevant standards. The next part describes graphical user interface, its options and several simulation topologies. The third part is a description of each simulated examples in NS-3 and proposal for their extension. It also includes analysis of the types of interference in PLC and partial extension.
