Single railway electrification system design
Svoboda, Ondřej ; Radil, Lukáš (referee) ; Pelc, Jiří (referee) ; Drápela, Jiří (advisor)
The main topic of the thesis is the design of single-track electrification of a direct current system of 3 kV and an alternating current system of 5 kV 50 Hz and then economically evaluate it over a period of 30 years. The work deals with basic traction systems and also deals with the calculation of main parameters of electric trains. The thesis describes in detail the procedure for the design of the electrification of the track and a partial introduction to the simulation programs that were used for energy calculations.
Analysis of ZED stereocamera in outdoor environment
Svoboda, Ondřej ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
The Master thesis is focused on analyzing stereo camera ZED in the outdoor environment. There is compared ZEDfu visual odometry with commonly used methods like GPS or wheel odometry. Moreover, the thesis includes analyses of SLAM in the changeable outdoor environment, too. The simultaneous mapping and localization in RTAB-Map were processed separately with SIFT and BRISK descriptors. The aim of this master thesis is to analyze the behaviour ZED camera in the outdoor environment for future implementation in mobile robotics.
Network Protocols Semiautomatic Diagnostics
Svoboda, Ondřej ; Ryšavý, Ondřej (referee) ; Holkovič, Martin (advisor)
This thesis is about semiautomatic network protocol diagnostics and creating protocol description from eavesdropped communication. Several network eavesdropping techniques  and some common programs for network analysis are introduced. Well-known network protocols are described, with focus on their communication messages. Some already existing methods for creating models from examples are mentioned and their characteristics defined. Next we design architecture of developed tool and some methods, that create protocol description. After that we explain implementation of this tool and finally the tool is tested and experimented with.
American foreign policy and Colombian peace process
Svoboda, Ondřej ; Raška, Francis (advisor) ; Kozák, Kryštof (referee)
This study analyzes American foreign policy with respect to Colombia since the beginning of the new millennium. The main pillar of this policy is a strategy called Plan Colombia. While the original reasoning behind Plan Colombia was to enforce better antinarcotic strategy to avoid cocaine distribution to the United States, by the time it morphed into a state-building effort. My main interest in this study is to answer the question whether Plan Colombia was successful and if so then whether it was a prerequisite for launching peace negotiations with the FARC and achieving durable peace. This study has several parts. At first, I shed a light into a situation in Colombia at the beginning of the new millennium and explain the motivation behind Plan Colombia. Next, I summarize the historical perspective and describe the most important events leading to the breakthrough which was the signing of the peace treaty with FARC. In the following section, I look more deeply into data about money transfers and I also analyze important socio-political indicators. In the conclusion, I explain why Plan Colombia was in my view a successful policy. I also discuss upon what was the success dependent.
Application of fluorescence staining for the "Scratch Wound Healing Assay" experiment
Zumberg, Inna ; Svoboda, Ondřej (referee) ; Baiazitova, Larisa (advisor)
This bachelor’s thesis studies the cell culture of 3T3 cell line (mouse embryonic fibroblast cells) and cell migration. The Scratch Wound Healing Assay was used for the study of cell migration. The basic principles of experimenting, its advantages and disadvantages, as well as the practical use of this method in scientific research were presented on specific examples. Practical part of the bachelor’s thesis describes the experiment in the cell laboratory including cell culture of 3T3 cell line. The proposed experiment was tested with a sufficient number of repetitions. The statistical processing of microscopic images was performed in the MATLAB programming environment.
Transfection of somatic cells using magnetic nanoparticles and their post-transfection localization
Pošustová, Veronika ; Skopalík, Josef (referee) ; Svoboda, Ondřej (advisor)
This bachelor thesis is focused on an experiment based on magnetic particles SPIO for transfection of 3T3 cells. Nanoparticle surface was modified with PEI and Chitosan to optimize this method. The transfection experiment was performed twelve times, then the scanned data was processed and statistically analyzed in Matlab R2016a to determine the transfection efficiency. The theoretical part is focused on magnetic nanoparticles and their application in medicine, on transfection and in last part on a transfection of cells using magnetic nanoparticles.
Investing on Atypical Market by Using the Business Intelligence tools
Svoboda, Ondřej ; Teršl, Michal (referee) ; Kříž, Jiří (advisor)
This thesis deals with summarization, processing, transformation and interpretation of large amounts of betting odds data. The goal of this thesis is to find out whether it is possible to invest in sports betting odds market without any previous knowledge about sport, using only mathematical skills and business intelligence tools.
Electrophysiological characterization of Kir2.1 membrane channel
Měsíčková, Klára ; Baiazitova, Larisa (referee) ; Svoboda, Ondřej (advisor)
The topic of this thesis is electrophysiological characterization of Kir2.1 membrane channel. Inward rectifier potassium channel Kir2.1 is located in muscular, heart and nerve cells and its dysfunction causes various diseases. Practical part of this stage is focused on cultivation of the HEK293T cell line that is used to transfection of the plasmid Kir2.1 and subsequent measurement of the ionic current through the electrophysiological method patch-clamp in whole-cell mode.
Measurements and usage of cross sections of various (n,chi n) threshold reactions
Chudoba, Petr ; Vrzalová, Jitka ; Svoboda, Ondřej ; Krása, Antonín ; Kugler, Andrej ; Majerle, Mitja ; Suchopár, Martin ; Wagner, Vladimír
Current trend in nuclear reactor physics is a transition from technologies using thermal neutrons to technologies utilizing fast neutrons. Unfortunately focus was put mainly on the thermal neutrons for a long time and lead to very good knowledge about this low energy region, but very scarce coverage of the high energy region. This means that there is a gap in the knowledge of excitation functions for higher energies. This gap spreads from 20 MeV up to 1 GeV and higher. This is exactly the energy region needed for description of advanced nuclear systems such as accelerator driven systems (ADS). Our group from Nuclear Physics Institute (NPI) of the CAS is a member of an international collaboration Energy & Transmutation of Radioactive Waste (E&T RAW). This collaboration focuses on ADS for many years. In order to measure neutron field within ADS models it is necessary to know excitation functions of reactions used to monitor the neutron field. In many cases there are almost no experimental data for suitable reactions. Worse and quite common case is that there are no data at all. Therefore we are also focusing on measurements of these data in order to fill the databases as well as to allow further improvements of codes for nuclear data calculations.
