Comparison of Plain Line Tamping Methods
Bombera, Jan ; Hartmann, Miroslav (referee) ; Svoboda, Richard (advisor)
The diploma´s thesis deals with evaluation of adjusted track tamping technology and its comparison with currently used technology. This is based on track geometry parameters measuring and its vertical movement on the test section, which was created on double track Břeclav – Přerov near Rohatec station. On this test section one line was tamped with the currently used method within regular maintenance work and the second line was tamped with the adjusted technology. The technology modification is based on application of increased number of tamping tines squeezing strokes, which results in a creation of bigger and more compacted sleeper bed. The point of this thesis is to verify, that the speed of the track geometry parameters degradation is smaller in case of adjusted technology use. Thanks to that it would be possible to extend the maintenance cycles in case of compliance with track parameters maintenance limits and traffic safety.

Measurement of the fans characteristic
Coufalík, Martin ; Štětina, Josef (referee) ; Katolický, Jaroslav (advisor)
This bachelor thesis discusses a fan characteristics and their measurement. The aim of this thesis is to compare the results of measurements, which were done in certified laboratory with results of measurements done in alternative measuring stands. In first part of the thesis are described the basic types of fans and inclusion fans in turbo–machines. Furthermore, the thesis deals with a particular fan, which is part of the combustion system of condensing boiler. This fan is also the object of measurement in practical measurements, which were measured as a part of this thesis. This practical part of the thesis includes also analysis of test track, the measurement procedure and all calculations according to ISO ČSN 5801. At first were carried out measurement in certified laboratory and then in three different measuring stands. In conclusion were these results compared with optimal results.

Effect of options measurement profile in the hydromeasuring process
Jurčová, Michaela ; Žoužela, Michal (referee) ; Zubík, Pavel (advisor)
This bachelor thesis is focused at effect of options measurement profile in the hydromeasuring process. When based on processing of acquired data sample we can determine proper relative distanc measurement profile behind outfall pipe. Determination of proper profile is based on condition that measurement error must be less than 5%. Measurements were assessed at testing track at institute of water structures. Outcome is graph of dependence of percent deviation of determined flow to relative distance behind outfall pipe and relative filling height.
