Plastic optical fibres and their application in practice
Bubela, Ondřej ; Tejkal, Vladimír (referee) ; Šporik, Jan (advisor)
The intention of this essay is familiarize readers with polymer optical fibers knowed as POF. Listing the losses factors (attenuation, dispersion) and transmition properties (bandwidth, index profiles). Describes production POF (suitable materials and methods), connecting with detachable and not detachable joints. Discuss and compares diference between GOF and POF. By measuring demostrates the complexity of compilation POF and GOF physical layers. Define the facts affecting transmission parameters. Trying to inform about economical possibilities.

Vibration and noise of electric vehicles
Winter, Josef ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This bachelor thesis deals with problematics with noises and vibrations else known as Noise, Vibration and Harshness (NVH) at electric vehicles type Battery Electric Vehicle. The attention is drawn to the powertrain system because the powertrain system was electrified. The goal of this thesis is to present sources of noise and vibrations and to show examples of experiments that are done on the vehicles to improve driving comfort of driver and passangers. In the end the measurement and analysis of noises and vibrations were done at electric vehicle by Hyundai from Institute of Automotive Engineering.
