Design, development and realization of vibration measurement on riding metro wheel with and without add-on damper
Pešek, Luděk ; Vaněk, František ; Vaněk, Petr ; Cibulka, Jan
The aim of this research was design, developement and realization of vibration measurement (acceleration) of the riding metro wheel with and without add-on damper. The radiotelemetric method with four measurement channels was used for the operational measurement of vibration and noise. The solution was devided into four steps a) design and devolopement, laboratory tests and production of modified radiotelemtric equipment for measurement on the tram wheel; b) installation of the sensors and radiotelemetric equipment; c) realization of vibration operational measurement; d) measured data processing. In the report there is described a methodology of measurement and dynamic analysis used for comparision of the wheel with and withoud add-on dampers. The different riding regimes and tracks, i.e. direct, bow , were analysed. The third octave spectra nd amplitude time-frequency characteristics of accelerations and acoustic pressure were evaluated from the digital recorded time signals.

Využití magnetorezistivních senzorů v dynamice strojů
Vaněk, František ; Cibulka, Jan ; Vaněk, Petr
Magnetoresistive sensors of rotation with analogue or digital outputs were introduced at Senzor 99 exhibition in Nurberg by Philips and Siemens. They proved their usefulness in diagnostics of machine parts vibrating due to rotation. The rotating part of a machine passing the sensor induces changes of the outer magnetic field and consequently the electrical resistance of the bridge is varied and then the corresponding output voltage measured. In the present contribution typical measurements taken from engineering practise and their analyses are presented.

Corporate culture of firm Hyundai
Vítková, Barbora ; Müllerová, Františka (advisor) ; Vaněk, Petr (referee)
The objective of this thesis is familiarization with firm Hyundai and approach of definite aspects, which had to be considered before the production plant was in Nošovice built. The aspects, which have to be considered and which I focused on in this thesis are, economic situation in Czech republic and Republic of Korea and also the cultural differences between Czech republic and Republic of Korea. The thesis is divided into three chapters and each of them contains theoretical part and practical example. The first chapter considers economic situation in Czech republic and also in Republic of Korea and their bilateral foreign trade. Second chapter is focused on czech and korean culture and shows differences and similarity of these cultures. Third chapter describes corporate culture of firm Hyundai. The work on the thesis was very interesting and enriching.

Lokalizace automobilových firem v České republice
Černovská, Stanislava ; Čadil, Jan (advisor) ; Vaněk, Petr (referee)
Práce se zabývá lokalizací automobilových firem v České republice. Hlavním cílem je zjistit lokalizační faktory nově příchozích firem automobilového průmyslu do České republiky. Práce se zaměřuje na historický vývoj lokalizačních teorií, ekonomické aspekty lokalizace, prostorovou analýzu (zejména na lokalizační kvocient a lokalizační křivku). Praktická část obsahuje charakteristiky dvou největších nově příchozích automobilových firem do České republiky, vyhodnocení dotazníkového šetření, výpočet lokalizačních kvocientů a sestavení lokalizační křivky.
