Risk analysis of siphon pipes
Outratová, Markéta ; Svoboda, Miroslav (referee) ; Ručka, Jan (advisor)
The master’s thesis discusses siphon pipes that are used to collect groundwater. The goal of work is to define the most frequent undesired events that may appear on siphon pipes, and verifying the individual springs. The work is addressed in accordance with the metodology of risk analysis WaterRisk. The content of the work is a summary of the hydraulic of siphon pipes and their use in practice, hazard identification, defining the most frequent undesired events and consequences on siphon pipes, and their verification in the spring in a particular case study.

The Third Track in Track Section Blansko - Rájec-Jestřebí
Šíp, Radek ; Hoza, Miroslav (referee) ; Svoboda, Richard (advisor)
The task of the thesis is to propose the third track in track section Blansko - Rájec-Jestřebí and increasing line speed with maximum use of existing track body and grounds of SŽDC, s.o. Next is the design of the reconstruction of all engineering objects (bridges, runoffs, railway crossings and platforms). Additioning of the third track will cause extensive structural modifications at railway stations Blansko and Rájec-Jestřebí. Within the building will be verified construction of new railway stop Spešov.

Direct digital frequency synthesizer
Svoboda, Josef ; Šebesta, Jiří (referee) ; Kasal, Miroslav (advisor)
Direct Digital Frequency Synthesis (DDFS) is a method of producing an analog waveform, usually a sine wave, by generating a time varying signal in digital form a then performing a digital to analog conversion. Because operations within a DDFS device are primarily digital, it can offer fast switching between output frequencies, fine frequency resolution and operation over a broad spectrum of frequencies.

Hydraulically driven screens
Svoboda, Jan ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis contains a short summary and overview of different types of screens. The thesis further deals with a design of hydraulically driven screens. Both analytical calculations and finite element method were used in the course of solution finding. The proposed of solution was created in 3D program Autodesk Inventor Proffesional 2013. Manufacturing of selected parts were also created in the same program.

Apartment building Lanškroun
Pecháček, Miroslav ; Svoboda, David (referee) ; Čupr, Karel (advisor)
The subject of the bachelor's thesis is the design of an apartment building in Lanškroun. It is a town in the district of Ústí nad orlicí in the Pardubice Region. The building has three floors above ground and one underground floor. In the basement there is a utility room, cellar and storage space. In the above-ground part of the building there are a total of 6 residential units of various sizes from 1+kk to 4+kk. On the second and third floors there is a balcony and on the third floor there is a covered terrace. The structural load-bearing system is made of ceramic blocks with ceramic ceilings, the stair construction is made of reinforced concrete monolithic and is connected to the ceilings. The building has an elevator.

Web Information System Design Proposal
Svoboda, Ondřej ; Koutný, Miroslav (referee) ; Dydowicz, Petr (advisor)
This bachelor’s thesis deals with evaluation and design of a website, where will also be designed information website system (further IS). It will have a form of a calendar and it should help the firm to better time planning, organization of work, guidance of employees and echo checking of information. In IS there will be modules for evidence of workers, customers, orders, services, costs and particular jobs. IS design will be like that so there is an opportunity to add extending modules.

Railway Tracks Possessions
Gelová, Zuzana ; Hoza, Miroslav (referee) ; Svoboda, Richard (advisor)
The Bachelor thesis deals with the costs quantification analysis of a particular track possession according to the New methodology. This thesis focuses to quantify costs of replacement transport, to analyse the influence of the track possession to surroundings and to analyse other factors. The first chapter describes the area of railway transport, in particular the concepts and laws concerning to railway track possessions. The second chapter describes the current situation, we learn about the regulations and procedures for the implementation of track possession according to SŽDC. The third chapter consists of goals of my thesis. The fourth chapter describes the principle of functioning of the New methodology. The fifth chapter consists of calculations and quantification of all alternatives of our track possession. The last chapter evaluates the cost results of all alternatives of our track possession. Summarized findings are used to define a better alternative of possession.

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.

Railway Platforms Construction
Smítková, Pavlína ; Hoza, Miroslav (referee) ; Svoboda, Richard (advisor)
This work is focused on comparison of platforms constructions used in railway network SŽDC, ŽSR, eventually other neighboring countries. The aim is to compare the platforms in terms of complexity construction, maintenance, structural stability, material demands, costs, possibiliti of track maintainance, possibility of out-of-gauge loads pass (necessary adjustments platforms), access for persons with reduced mobility and orientation. There are drawings of different type sof platform cross sections in this bachelors thesis. The aim is to recommend the most appropriate design or platform position with respekt to the above requirements.
