Structural analysis of part of electrical machine
Fodor, Viktor ; Hájek, Vítězslav (referee) ; Janda, Marcel (advisor)
This thesis discusses the optical diagnostics of electrical motor parts using a 3D scanner. It describes the construction of electrical induction motors, their heat losses, cooling and refrigeration systems that may be used by such motors. It approaches the possibilities of heat recording and briefly explains the 3D scanner’s principal. It also introduces the simulation program ANSYS which uses the finite element method. This thesis shows the post processing of the digitalized object and the simulations and compares the simulation and measurement results. The final part is devoted to the analysis of the obtained results.

Noise measurement of electric machines
Fodor, Viktor ; Vítek, Ondřej (referee) ; Janda, Marcel (advisor)
This work discusses the problem of generating noise in electrical rotating machines, engines. First we explain what noise and sound is, its characteristics, its distribution in machines. Then we discuss the possible sources of noise in electrical motors and the possible reduction of noise. To verify the theory mentioned in this work, we will execute a noise measuring on an induction engine. Further we realize a measurement of the operating curve of the machine. Finally, we describe various measurements.

Animation services in the Czech Republic
Fodor, Viktor ; Jenčková, Jiřina (advisor) ; Kalábová, Markéta (referee)
The diploma thesis deals with animation services as the important complementary service of tourism industry. The introductory part theoretically specifies the term animation and determines its history. It also explains main elements that affect animation. Furthermore, it clarifies the profession of animator and activity of animation team. The next part of the thesis analyses the functioning of animation services of the holders of the tourism offer in the Czech Republic, particularly in hotels, water parks, swimming pools and spas. The final part of the thesis summarizes suggestions that could improve the level of animation services in this country.
