Design of Modernization of Polička Railway Station
Zvejška, Ivo ; Burda, Petr (referee) ; Plášek, Otto (advisor)
The goal of the diploma thesis is a design of the reconstruction of the Polička railway station in aim to fulfil the requirements for the movement of people with reduced mobility. It was necessary to design platforms with a height of the platform edge 550 mm above rail level. It was also required to increase the design speed in main tracks as well as to reconstruct conections of sidings. There was also included the design of reconstruction of drainage system of railway tracks.

The load bearing structure of multi-storey reinforced concrete builidng
Burda, Patrik ; Švaříčková, Ivana (referee) ; Šimůnek, Petr (advisor)
The diploma thesis is focused on design on loadbearing reinforced concrete structure of multi-storey apartment building with shops and offices on the ground floor and underground garage. The thesis consists of the analysis and design of ceiling slabs above underground floor, supporting columns and the beam under the underground floor ceiling slab. Calculation 3D model was created to determine internal forces. All structures are designed according to EC2, ČSN EN 1992-1-1. The thesis includes elaboration of static calculation, shape drawings, drawings of reinforcement of solved structures. The rest of the project part are not analysed.

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.

Preparation of Ag/Co/Ag Trilayers
Burda, Pavel ; Kolíbal, Miroslav (referee) ; Čechal, Jan (advisor)
The Bachelor's thesis is aimed to the preparation of silver and cobalt ultrathin films. The films are formed on modified surfaces of crystalline silicon substrates (SiO2/Si(111), Si(111) ?H, Si(111) 7×7) and amorphous SiO2 in a form of a quartz glass. Thin films are grown using an effusion cell for Molecular Beam Epitaxy (MBE). Surface modified surfaces are covered subsequently by a silver, cobalt and silver thin layer. The individual film thickness is 6 nm. Consequently the samples are studied by the X-ray Photoelectron Spectroscopy (XPS) and the Atomic Force Microscopy (AFM). The morphology of thin films and growth modes are compared among the substrates. Growth modes change with the surface modification type. Complete trilayer system Ag/Co/Ag was prepared on SiO2/Si(111) and Si(111) 7×7. Such system can be employed in plasmonics in order to allow the control of surface plasmon polariton properties by an external magnetic field.

Design of Optimization of Track Section Branná - Ostružná in km 12,677 - 15,3
Veselý, Miroslav ; Burda, Petr (referee) ; Plášek, Otto (advisor)
The objective of my thesis is to propose a given section of line optimization of geometrical parameters of tracks, and also to increase the line speed. Another task is to design a suitable structure of the railway bed due to the speed category of track and traffic load, and propose a suitable design sleeper base. In addition to design a type of construction at level crossings, the crossings without AD then add necessary view triangles.

Inteligent battery charger controled by microcontroler
Burda, Petr ; Magát, Martin (referee) ; Pavlík, Michal (advisor)
Universal, smart battery charger NI-Cd, NI-MH, Li-Ion a Li-Pol batteries with adjustable voltage incremental rotary position sensor in the range of 0 -25 V and currnet up to 1 A load.The charger is controlled by microcontroller ATMEGA32 – 16PU Atmel and provides thermal protection and management of the chrging voltage depending on the temperature inside the battery pack or battery cells. Setting is made througth LCD screen to be displayed in addition to the set temperature, charging voltage and battery current. To save the profile is used EEPROM memory, which is contained in the microcontroller.
