Electronic control of servomechanism for drive-simulator
Valouch, Martin ; Šebesta, Jiří (referee) ; Fedra, Zbyněk (advisor)
The aim of this bachelor´s thesis was construct electronic driving unit of positioning servomechanism in driving simulator. As controlling unit was chosen 8-bit microcontroller ATmega16 produced by ATMEL® and for scan actual angle of displacement the seat magnetic rotation encoder AS5040 produced by Austriamicrosystems®. For construction of bridge circuit were chosen MOS transistors. This transistors are excited by two Power MOSFET Drivers. Their job is convert output signal TTL logic from microcontroller to voltage in needed norm for transistors circuit closing. Data from PC in drive simulator can be transfer by serial interface RS485 or RS232.

Wireless interface for digitally-controlled applications
Valouch, Martin ; Rumánek,, Jaroslav (referee) ; Brančík, Lubomír (advisor)
The thesis aim is in practical realization of wireless interface, which is created by infrared relay in motorcycle Simson. Infrared relay is used for speed measuring. This work describes the realization of digital controlling by microcontrollers. Digital controlling can easily improve and upgrade functions for better driving comfort. It’s possible by getting information about condition of selected motorcycle parts. This information can be engine temperature, battery charge, total distance and etc.

Monitoring raných sukcesních stádií na plochách po velkoplošném rozpadu bučin
Valouch, Martin
This thessis deals with assessment of the actual state of an herb layer and regeneration in nature preservations Coufavá and Slunná. Both of nature preservations were affected large-scale wind disturbances. The survey was conducted in June and July 2013. There were totally performed 384 phytosocenological releves (162 in nature preserve Coufavá and 222 in nature preserve Slunná). Research was carried out on a regular grid 15 × 15 meters. There were 254 juvenile trees which were founded in nature preserve Coufavá and also 1891 juvenile trees were founded in nature preserve Slunná. In both of preservations browse didn't rise up 10 % from all regeneration. Most abundant tree species in nature preserve Coufavá were Fagus sylvatica. In nature preserve Slunná were most abundant Tilia sp. Strong clonal species dominated in disturbed desktop non-wood undergrowth in both of studied areas. In closed stand dominated typical forest species. Impatiens parviflora has abundant occurrence in both of biotopes. For both nature preserves was estimated future development and propose of solutions. Result of work should serve as a basis for optimizing the management plan for the said reservation.
