Optimization of foundry technology for the production of piston from Al alloy
Poláček, Adam ; Pernica, Vítězslav (referee) ; Krutiš, Vladimír (advisor)
The aim of work is to optimize the casting solidification technology to reduce or completely eliminate defects. The literary part of the work deals with materials, production technology and defects in the pistons of internal combustion engines and compressors. In the design part of the work, an analysis of the occurring defects is performed. X-ray examination and the cut of the piston are conducted to investigate the causes of their formation. Subsequently, the simulation of the current production technology is carried out and technological modifications to the cooling process are proposed. These modifications are verified through simulation and in the conclusion are compared in terms of their effectiveness in reducing the occurrence of defects.

Optical network design
Polaček, Adam ; Tomašov, Adrián (referee) ; Horváth, Tomáš (advisor)
This bachelor thesis deals with the design of a technological optical network for the area of Hradec Králové, for the company ČEZD Distribuce. The theoretical part of the thesis describes the current network design and discusses network protocols. The practical part of the thesis describes the passive part and the logical part of the network. An important part of the thesis, is the fiber scheme and configuration design for router and switch. In the last part of the thesis, simulation in GNS-3 program is shown.
