Milling spindle thermal model
 Chlapek, Ondřej ; Musil, Filip (referee) ; Hadraba, Petr (advisor)
The aim of this thesis is to create two thermal models (black box and grey box), which would allow to predict the development of the milling spindle temperature, based on measured operating data. The accuracy of both created models was determined by statistical methods, and the models were compared with each other.
Detailed record
Use of a thermoelectric generator for increasing heat recovery
 Laga, Ondřej ; Janák, Luděk (referee) ; Vlach, Radek (advisor)
This thesis deals with the problem of waste heat, namely, the exhaust gas which are not frequently used. Specifically, it is a design of thermoelectric generators set, power electronics for fan and heat exchanger proposal. The entire system uses the energy of the waste heat to increase the heating efficiency.

Design of temperature control of power electronic element of device for radio transmission
 Laga, Ondřej ; Kotrba, Vít (referee) ; Vlach, Radek (advisor)
This work deals with the problem of overheating power devices for radio transmission, namely transmitting vacuum tubes, which often reach a high temperature by the maximum operating of this. This is the design of temperature control for this device.
