The analysis of dynamic effects in the frog region of railway turnout
Balash, Arsen ; Pazdera, Luboš (referee) ; Smutný, Jaroslav (advisor)
This thesis is focused on measurement and analysis of dynamic effects on railway turnouts. Two same-type turnouts with different fastening elasticity were chosen. My attention was focused mainly on the crossing part of the turnout, where the highest dynamic impacts occur. The point of the thesis is comparison of the crossing part of turnouts in term of dynamic behaviour and assessment of influence of soft rail pads on spread of dynamic energy through the construction. A part of the thesis is choice of methodology of the measurement and proposal of convenient mathematical apparatus for analysing of the dynamic effects on crossings.

Technology of Online Voting Systems
Kováč, Michal ; Sedláček, Pavel (referee) ; Froehling, Kenneth (advisor)
Tato práce pojednává o konceptu volení online. Krátce popisuje jaké další volební metody se v demokratických zemí používají. Detailně popisuje země které používají online volení (celostátně a částečně) a take země, které pilotovali nebo zkoušeli používat online volby a také z jakého důvodu přestali. V posledních dvou částech se práce zabývá pozitivy a negativy které online volební systémy mohou představovat, včetně analýzy volebních dat z Estonska.

Upgrading of Viskafors Railway Station
Blaňková, Monika ; Melecký, Martin (referee) ; Svoboda, Richard (advisor)
The main aim of the diploma thesis is reconstruction of Viskafors railway station and its adjacent track at KM146+ 800 - 145+ 700 so as to satisfy the current traffic and at the same time the legislation is met. The tracks geometry and turnouts in the station was solved according to Swedish and Czech standards and conventions. As part of the reconstruction, the connection of the service track was resolved from the north side.

Design of junction point Jistebník
Talapka, Filip ; Janoušek, Jan (referee) ; Plášek, Otto (advisor)
The aim of this bachelor thesis is to design a rail connection between the corridor track Přerov – Ostrava and a high-speed track Přerov – Ostrava near the village Jistebník. The flyover interconnections are designed in all four directions for a maximum speed of 160 km / h. The proposal is divided into two basic variants – the minimization of land occupation and the minimization of engineering objects.

Controller for the Model Railway Based on FITKit
Kandrik, Ján ; Kotásek, Zdeněk (referee) ; Straka, Martin (advisor)
This work discusses a controller for model railroad derived from a state-of-art railway interlocking system, electronic signalbox. Work of interlocking and model railroad signalling issues are described among the design and implementation parts of such system. Also analyses creation of parts for the controller using FITkit, a microcontroller educational platform.

Speed Increasing for Track Section Křenovice - Nezamyslice
Bombera, Jan ; Kroupa, Jan (referee) ; Svoboda, Richard (advisor)
Bachelor´s thesis deals with the possibility of increasing the line speed at Křenovice – Nezamyslice track number 315A. Speed increasing is tested in two steps – with current track geometry parameters and with changing some of the track geometry parameters, but always in order to meet regulatory and normative limit values. The new speed is determined for conventional vehicles and for vehicles that are able to take advantage of cant deficiency I > 100 mm. Speed limits in locations of railway crossings, signals position, etc., are taken into account for speed increasing. In some cases are proposed measures to change these objects.

Upgrading of Praha Liběň Locomotive Servicing Depot
Ondra, Michal ; Burda, Petr (referee) ; Svoboda, Richard (advisor)
The topic of my thesis is to study the complex reconstruction of the locomotive servicing depot Praha Liben. The locomotive depot is both operational maintenance and repair trains. The section reconstruction begins in turnout number 1, the whole area locomotive depot will be reconstructed. The main task is to propose an exchange of stepped old construction turnout for turnout new one in the whole area of the depot. The total number of changed points is 27. Depot demolition tasks in order to extend the track number 10 on the minimum usable effective length of 105 meters is the other task. Establishment of two dead-end tracks number 15 and 17 will be extend to an effective length of 105 metres. Retaining wall with PU componentsis designed along track 17. The next task is to solve the drainage area. The area will be drained interconnected system drains into the sewer and trench walls.
