Carbon Capture Storage/Utilization
Šuráň, Michal ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
The bachelor thesis deals with the issue of CCS and CCU. The main objective is a research of capture, transport, storage and utilization of carbon dioxide, specifically technologies associated with the combustion of fossil and biomass resources. The first part describes fuel transformations and subsequent separation technologies. The second part explains the transport of CO2. The third and fourth chapters refer to methods of storing and using carbon dioxide. The last section focuses on the issue of CO2 capture using biomass resources.

Engineering solutions for mitigation of climate change - methods applicable at the source of greenhouse gases
Remeková, Valentína ; Jedelský, Jan (referee) ; Lízal, František (advisor)
This work aimed to produce a research study on the topic of engineering solutions designed to mitigate climate change and which are applicable at the source of greenhouse gases. The first part outlines the fundamental matters of climate change. The second part focuses on technologies CCS (Carbon capture and storage) which capture and sequester carbon dioxide and possible options for separating CO2 from flue gases. The third chapter describes technologies CCU (Carbon capture and utilization) that use captured carbon as a product for further use. The future of these technologies and other abatement methods are addressed in the following section. The financial aspects of solutions for climate change mitigation are discussed in chapter five. The last part summarizes the main advantages, disadvantages, findings, and limitations of research.

Assessment of CCS and CCU methods
Kroupa, Zdeněk ; Škorpík, Jiří (referee) ; Baláš, Marek (advisor)
The thesis focuses on CCS and CCU technologies, which could find application in industry and other sectors in the future. These technologies are used to reduce CO2 emissions, mainly from point sources. This thesis provides a comprehensive overview and division of CCS and CCU technologies and points out negative effects of its installation. Part of the work is also a comparison of individual steps of technology, both from an energetic and financial point of view. The aim is to show a wide range of influences on the final price and a significant discrepancy in the results of some scientific works. At the same time, in some parts, you can find a detailed description of individual parts of the technology.

Methods and prospects of CCS from emissions of energy sources in ČR
Pulkrábek, Jan ; Hovorka, Jan (referee) ; Přibil, Rudolf (advisor)
With increasing frequency of problems caused by global climate change, the scientific community trying to find possible solutions to reduce greenhouse gas emissions into the atmosphere. One of the possible solutions of this problem is considered the system of separation, transportation and long-term storage of C02, called CCS - Carbon Capture and Storage. This work is a literature review issues of CCS in order to determine the possible use of CCS in the Czech republic. There is a basic system description of CCS, the possible environmental risks associated with it, and finall summarize of the prospects of deployment CCS technology in Czech republic.

Automatic Text Recognition for Robots
Hartman, Zdeněk ; Materna, Zdeněk (referee) ; Španěl, Michal (advisor)
This bachelor thesis describe module design for text detection and recognition for use in robotic systems. To detect charters is used Stroke Width transform, which is applied on the input edge image. In the output image after Stroke Width transform are found connected components. For letter grouping into a words is used Hough transform, which is applied on the created binary image. This image contains points, which corresponding positions of found connected components. To recognize signs in detected areas is used Tesseract library. Before recognition detected areas are extracted and rotated into a horizontal position. This proposed detector can detect even rotated text. Accuracy of detection of the text is 75% above the test set "informační tabule".

Possibilities of connecting the Asterisk softswitch to the 4th generation PBX
Halamík, Zdeněk ; Krajsa, Ondřej (referee) ; Šilhavý, Pavel (advisor)
This master’s thesis dissertate the possibilities of the linkage between Asterisk softswitch and the 4th generation private branch exchange. This should create a new generation’s network, so-called NGN, by the convergence of existing telecommunication networks with an IP computer network. This master’s thesis is divided into several chapters. In introduction is described the evolution of the private branch exchanges as well as the principles of the voice digitizing, codecs and signaling commonly used in both TDM and VoIP networks. The main aim of this project is the configuration of Asterisk software exchange for connection with PBX Alcatel 4400 as well as public phone network PSTN. Another goal of this master’s thesis was the configuration of Alcatel PBX and diagnostics of CCS and CAS signaling on E1 interface. In conclusion there are summarized advantages of NGN networks and their utilization in the future.

Dissolution of silicates for carbon dioxide mineral storage
Křečková, Magdaléna ; Havlica, Jaromír (referee) ; Ptáček, Petr (advisor)
The degradability of wollastonite, montmorillonite and talc in an aqueous solution of acetic acid at different temperatures is main object of this study. Mineral carbonation, i.e. the reaction of calcium and magnesium presented in these three silicates, is a novel and promising approach to carbon dioxide capture and long-term storage. The kinetic of wollastonite, montmorillonite and talc dissolution is studied due to assessment of their efficiency for CCS technologies. The dissolution kinetic is discovered with using measured time dependence of Ca2+ and Mg2+ leached ions concentration.
