Precise Positioning of Railway Primary System Using Gnss Technology in Operating Conditions
Bureš, Jiří ; Vystavěl, Ondřej
The paper deals with the analysis of the accuracy of the real-time GNSS measurement procedure used in railway operating conditions. The accuracy achieved in operating conditions is compared with the accuracy obtained on a calibration base using the same measurement procedure. The consistency between the accuracies of the primary system (satellite-determined) and the secondary system (terrestrially measured by the traverse method) is also discussed. The analysis includes the problem of residual inhomogeneities of the uniform transformation key when transformed to S-JTSK.

Railway track deformation measurement
Leischner, Ludvík ; Bureš, Jiří (referee) ; Švábenský, Otakar (advisor)
This bachelor thesis is about measuring deformations on railway bridge in Znojmo. The horizontal and vertical changes of railway track on the bridge and newly renovated bridge construction were measured by using two independent methods, namely 3D polar method and kinematic GNSS Stop & Go method. The assessment of the longitudinal shifts depending on atmospheric conditions especially the temperature changes is an essential goal of this work. Another key aim is the determination of precision of both independ-ent measuring methods.

Proposal of topology of piezoceramic composite sensor
Dostal, Vojtěch ; Ševeček, Oldřich (referee) ; Majer, Zdeněk (advisor)
This master thesis deals with design and numerical modelling of piezoceramic sensor, which is placed on a rail, in order to generate electrical energy, which can be used for wireless monitoring of railway traffic and to monitor the condition of the railway. The thesis is divided into three parts. Theoretically background of piezoelectric energy harvesting is described in first part, where some previous application of piezoelectric generator in railway area are shown. In the second part, parametric analysis of numerical model is performed, which directly leads to finding best location on a rail, where piezoelectric generator should be placed. For this analysis the homogenized model of MFC sensor was used. Results of the numerical model were then compared with the results of the conducted experiment. The third part presented own design of piezoceramic sensor, which is placed onto most suitable location on a rail. Results from numerical analysis shown eligibility of using piezoceramic sensor to monitor the railway traffic.

NorthEast segment of Hranice town bypass
Kelča, Petr ; Jakl, Tomáš (referee) ; Všetečka, Martin (advisor)
The aim of this diploma thesis is to elaborate a variant of the technical solution of the Northeast bypass road of the city Hranice and its subsequent comparison with other variant prepared by the company Linio Plan, s.r.o. The main task of the bypass road is the operation of the industrial zone, through which is achieved the relocation of a large part of the transit traffic from the city centre. The basic difference of compared variants is their location to the city, the solution developed by Linio Plan, s.r.o. passes through the industrial zone and the other variant passes outside this zone.

UIC codes detection and recognition
Zemčík, Tomáš ; Richter, Miloslav (referee) ; Janáková, Ilona (advisor)
Machine detection and reading of UIC identification codes on railway rolling stock allows for automation of some processes on the railway and makes running of the railway safer and more efficient. This thesis provides insight into the problem of machine text detection and reading. It further proposes and implements a solution to the problem of reading UIC codes in line camera scanned images.

Primary Architecture / Architecture is Coming
Ivkovičová, Natálie ; Eichlerová, Eva (referee) ; Ponešová, Barbora (advisor)
The aim of the work is to find a suitable way and solution of mediating architecture and its broad themes into the lives of the public. To design an ideal space and suitable conditions for the popularization not only of architecture, but also of related fields such as art, landscape architecture and construction, where all these disciplines will be connected. The main part of the design is to find a suitable way to "transfer" architecture from large cities and those in which it is taught to regional cities or villages. This way of presentation and sharing would be carried out by mobile pavilions, which would create mobile studios. The entire system will be coordinated and managed by the building, where these mobile pavilions will be merged and modularized. The building will create a "center of architecture", where all functions will be combined. This centre serves as a complementary function to the schools of architecture, civil engineering, fine arts and landscape architecture. Thus, there will be cooperation between students across all disciplines with a place for presentation and exhibition to the public.

Holesov Station Reconstruction
Ludvíková, Lilija ; Šmíd, Jaroslav (referee) ; Říha, Tomáš (advisor)
The master’s thesis deals with upgrading of the Holešov railway station. The goal is to design a solution suitable for the capacity for a current traffic and valid legislation. Required are two boarding edges in the length of 130 meters enabling access to persons with reduced mobility and orientation, adjustments or renovation of a station throat triggered by insertion of platforms, maximizing line speed and design of railway superstructure and substructure design including drainage.

Design of a contemporary city district in the environment of the historic city.
Landa, Karel ; Obrtlík,, Jan (referee) ; Májek, Jan (advisor)
The assignment of the diploma thesis was set to design new structure inside of historic city, which in the past went through major changes due to construction of main road leading through and dividing it to the 2 parts by creating a psychological barrier. This road was built mainly because of the construction of nuclear plant Dukovany to transit its part and component via this road. Simultaneously the thesis assignment was to design new bus station to replace existing one which is oversized from its completion and to incorporate this bus station to the life of the city. In my proposal I was creating the city structure by using principles set by historic structure of the city adapted to modern normative requirements while finding new genius loci of the area, which is in my proposal created by uncovering the Stařečka stream, which was hidden by construction of bus station. Next goal of the proposal was to improve possibility to walk faster through city by creating shortcuts and paths for the main and most important users of the city which are the people.

Preparation and realization of the railway viaduct in Ostrov nad Oslavou
Šťastný, Jiří ; Doubek, Rostislav (referee) ; Kantová, Radka (advisor)
This Diploma thesis deals with the preparation of the realization of the railway viaduct in Ostrov nad Oslavou. Realization of major technological stages is addressed in building technological study. Technological processes of each sub-job phases are supplemented by technical regulations, the design of the main building machines and mechanisms, inspection and test plan, schedule of occupational health and safety, time and financial plan construction, construction budget, a plan for securing material resources. I also worked out the technical report of the building sites facilities including drawings needed. I also worked out design rehabilitation of the substructure of the railway viaduct, which is consist of technical regulations for remediation work and drawings.
