Non-filtering applications with current and voltage conveyors
Horáček, Lukáš ; Herencsár, Norbert (referee) ; Mišurec, Jiří (advisor)
This thesis is focused on using non-filtering applications with voltage and electric current conveyors. Conveyors may be used both for filtering and for non-filtering applications. They are basic elements of many modern electric circuits and operational amplifiers. First of all, I had described what the conveyor in general is, its historical development, which types of them we can meet with and its availability in integrated circuits. Then I focused on circuits which are subject of this thesis. Namely they are: functional transducer, rectifier and integrator. These circuits were analyzed and simulated by computer software. After this I designed their realization and performed experimental measurement.

Comparison of HomePlug broadband systems and DS2 technology PLC
Horáček, Lukáš ; Zeman, Václav (referee) ; Mišurec, Jiří (advisor)
This thesis comparing broadband systems HomePlug and DS2 PLC technology (Power Line Communications). PLC is a technology for transmitting data over electrical power distribution network. The theoretical part consists of describing a system for broadband data communication over high-tension lines, the selection criteria, a description of DS2 and HomePlug (variants of chips, version, network architecture, elements). There are also described modulation techniques, interference, standards, standard ISO 50065 and access methods. The practical part consists of laboratory measurements with both systems. For the testing were used DS2 modems from the company Defidev and HomePlug modems from AirLive. These are then compared according to selected criteria.

Proposal to improve the marketing communication of the company
Horáček, Lukáš ; Paďourová, Tereza (referee) ; Havíř, David (advisor)
This bachelor thesis deals with the topic of marketing communication in the concrete company called Truhlářství Augusta. In the first part I focus on the theoretical basis and introduction into marketing issues. These information are essential for subchapters of the thesis. The analytical part contains analysis of marketing and communication mix. The next part brings concrete proposals to improve the current situation. Based on that, I present opportunities to increase brand awareness in the Internet environment, especially through social media and company website, the possibility of using free space for advertising, recruitment campaign in the social media environment, proposals for promotional materials, local sponsorship opportunities and the use of fairs. The final part contains an estimate of the cost of the relevant proposals and their overall evaluation.
