Veseli Nad Moravou Station Reconstruction
Klar, Vít ; Sobotka, Lukáš (referee) ; Říha, Tomáš (advisor)
The subject of the Master's thesis is to design the redevelopment of the Veseli nad Moravou railway station. This renovation will include renewal of both, railway superstructure and substructure, including drainage system and new platform construcion proposal in order to meet current legislation regarding access of persons with reduced mibility and orientation skills. This thesis also deals with design of the track geometry compoments and geometry of set of switches at both heads of the railway station to fulfill the maximum train velocity demands at certain tracks. Last but not least, the rail track scheme of the station has been simplified.

Audio speaker system with baffle made from alternative materials
Hüttl, Ondřej ; Schimmel, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This thesis firstly consists of an analysis and a description of materials suitable for construction of loudspeaker enclosures and a design of the loudspeaker system with the enclosure made of a synthetic stone. Electro – acoustics drivers have been described with a focus to a frequency range, a principle and a construction for an explanation of their function. Drivers based on electrodynamic principle have been described closely. An analysis of materials used for the loudspeaker enclosure production has been done and tradicional and alternative materials have been described as well. Specific modulus, density and stiffness have been taken as an objective evaluative criterion. An evaluation indicates appropriate properties of plastic, aluminum and stone based materials. The function and kinds of loudspeaker enclosures have been described. The function, properties and design of a vented box loudspeaker system have been described closely. The last part of this thesis is individual design of a two-way vented box loudspeaker system with the enclosure made of synthetic stone. A simulation of a driver behavior built in the enclosure and compensation circuits and crossovers design and simulation have been done. The enclosure has been designed with high stress to minimize negative effect of the enclosure to the final sound quality.
