Train transport
Netolický, Jan ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This bachelor thesis deals with train transport. Train transport has been with us for many years and is constantly evolving. Many years have passed since the early days when rail vehicles were only used for transporting materials in mines, and today's rail vehicles serve as one of the main means of transport all over the world. The congestion of road transport is contributing to the use and development of train transport and thus to the increased speed and comfort that the carriers are trying to offer us. For this reason, the trains have been divided according to different criteria and the distance of their journey. Freight trains have also been included. Because of the constant increase in speed, more space has been given to high-speed trains, which have been divided into individual high-speed families. This overview of the trains gives us an indication of the direction of future development. As the Czech Republic has an extensive rail network, the paper includes an assessment of future developments in terms of speed increases, electrification and freight transport. As a result of the thesis, a breakdown and overview of current trainsets is presented, from which trends in this sector have been drawn. The thesis also concludes with a critical assessment of future developments in the Czech Republic.

Human Activity Recognition Using Smartphone
Novák, Andrej ; Červenák, Rastislav (referee) ; Burget, Radim (advisor)
The increase of mobile smartphones continues to grow and with it the demand for automation and use of the most offered aspects of the phone, whether in medicine (health care and surveillance) or in user applications (automatic recognition of position, etc.). As part of this work has been created the designs and implementation of the system for the recognition of human activity on the basis of data processing from sensors of smartphones, along with the determination of the optimal parameters, recovery success rate and comparison of individual evaluation. Other benefits include a draft format and displaying numerous training set consisting of real contributions and their manual evaluation. In addition to the main benefits, the software tool was created to allow the validation of the elements of the training set and acquisition of features from this set and software, that is able with the help of deep learning to train models and then test them.

Study of dynamic effect on a bridge structure with moving loads
Zavřelová, Michaela ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The goal of the master thesis is a dynamic parametric study on the dynamic effects of high-speed train using the HSLM-A load model on a railway bridge. The calculation model is processed, in RFEM 5.29.01 with RF-MOVE module and prerelease versions RFEM 6 and RSTAB 9, as a 2D member in the XZ plane. Furthermore, static load cases and load models LM 71 and HSLM-A are created. The HSLM-A load model is processed for universal trains A1-A10, which each cross the railway bridge at a total of 15 speeds ranging from 120 km/h to 400 km/h. A detailed parametric study of the dependence of the maximum deformation and acceleration in the Z direction on the speeds of each train set is performed. Modal and time history analysis is used in the parametric study. Part of the work is to determine the resonance region.
