Short path optical wireless link design
Kovář, Ondřej ; Látal, Jan (referee) ; Diblík, Jan (advisor)
This diploma thesis is focused on design and prototyping of wireless optical link for an indoor usage. In the beginning of the thesis frequency spectrums of infrared, visible and ultraviolet light are described by its typical qualities such as values of attenuation or reflection capability. On the basis of this analysis, a proper wavelength has been chosen for usage at the engineered communication system. Next part is devoted to selection of suitable communication components on basis of its declared qualities. In the following chapter this qualities are in carefully measured and after that they are compared with values provided by its manufacturer. The following section is devoted to design schemes of transceiver modules. After completion of the design the manufacturing of PCB, mounting components and the analysis of their distribution was described. The last part of this thesis deals with testing of created prototype in terms of maximum transmission distances and operating frequencies. At the very end of this project, in one small section ways to improve system characteristics was discussed.

Laser diode driver
Pučálka, Jan ; Látal, Jan (referee) ; Diblík, Jan (advisor)
The thesis describes the function and an energizer fount design for a laser diode.The main aim was to be familiarized with the requirements for the laser diode construction and to realize the equipment which enables an intensive modulation of a radiated cluster accompanied with a dynamics at least 80% of a maximum radiated output. The introduction of the thesis is focused on the issue of the primary features and elementary ideas concerning the matter of the laser. Moreover the types, infiltration application and the essential laser diode wiring are defined.The conclusion of the thesis is concentrated on the energizer fount linkage for the laser diode.

Upgrading of Ostružná and Horní Lipová Railway Stations
Látal, Jan ; Bubníková, Dana (referee) ; Svoboda, Richard (advisor)
The result of this work will be design the reconstruction of the railway station Ostružná and Horní Lipová to fulfil the following conditions. It must be ensured smooth movement of persons with reduced mobility in the sense amended by Decree 398/2009 Coll., also endeavor will be made an extension length of the platforms and useful length of the tracks, edit directional and height parameters to the requirements of the current standards and the associated construction of a functional drainage. However, it is avoiding the extensive work to minimize investment.

Speed Increasing for Track Section Čejč - Hodonín
Látal, Jan ; Komárek, Jan (referee) ; Svoboda, Richard (advisor)
This bachelor´s thesis will examine the possibility of increasing the line speed in the track section Čejč - Hodonín. The proposed rate increase will be considered in two variants, the first version based on the retention of geometrical parameters of the current track, the second option will involve changes of the track geometry parameters. These changes, however, may not cause significant interference with the body lines. Both cases must also be seen in the speed limit in areas of railway crossings, railway branching, position lights, etc., or its possible proposed the change of this objects.

Reform of the Common Agricultural Policy of the EU and Agricultural Negotiations in the Framework of the World Trade Organization
Drbohlavová, Marta ; Urban, Luděk (advisor) ; Látal, Jan (referee)
The main topic of this diploma thesis is the recent reform of the Common Agricultural Policy of the European Union (CAP). The second topic is the agricultural negotiations in the framework of the World Trade Organization (WTO). Last but not least, the question of the influence of the negotiations in the WTO on the CAP reform is discussed. The first chapter concerns with the details of the process of the CAP reform and it also shows the main differences between the previous forms of the CAP and reformed one (e.g. the reforms to the intervention mechanism). Secondly, this chapter includes the description and the analysis of the fundamental key elements of the new CAP - the single farm payment (SFP), cross compliance, modulation and rural development. It is expected that the SFP brings visible and necessary changes in the financing of the CAP. The SFP decouples the payments and production. In the future farmers make decisions firmly according to the situation on the market. There is no more any incentive for the production. Full decoupling was an ideal presented by the European Commission. Member states, however, decide to maintain a proportion of direct aids to farmers in their existing form. It means hat in some sectors the idea of the full decoupling is not brought into being. The reform also emphasizes...
