Transmission of accurate time and stable frequency through the optical network
Girt, Lukáš ; Horváth, Tomáš (referee) ; Vojtěch, Josef (advisor)
Diploma thesis focuses on the theoretical analysis of precise time and stable frequency transfer. It describes what time and frequency is, their properites and options of their generation. Next part deals with different possibilities of time and frequency transfer especially using fiber optics. In the practical part equipment for analysing effects of temperature changes on precise time transfer is puted into operation. Arduino platform is used for monitoring temperature changes on fiber. For testing of frequency stability in variable temperature conditions of environmental chamber device is created using highly coherent laser.

Peltier element based tankless heater/cooler
Girt, Lukáš ; Hanák, Pavel (referee) ; Kuparowitz, Tomáš (advisor)
Barchelor thesis focuses on the design of tankless heating and cooling using Peltier elements. The theoretical part deals with conventional cooling capabilities, principles and options of using Peltier elements and considerate issues of design for use in the food industry. In the practical part, author focuses on the design and construction of mechanical parts, design and construction of processor controled power source. Final device is compared to the alternative commercial product and possibilities of real usage are considered.
