Effect of compaction pressure to the electrochemical properties of the electrodes for Li-S accumulators
Jaššo, Kamil ; Tichý, Jiří (referee) ; Kazda, Tomáš (advisor)
The purpose of this diploma thesis is to describe the impact of compaction pressure on the electrochemical parameters of lithium-sulfur batteries. Theoretical part of this thesis contains briefly described terminology and general issues of batteries and their division. Every kind of battery is provided with a closer description of a specific battery type. A separate chapter is dedicated to lithium cells, mainly lithium-ion batteries. Considering various composition of lithium-ion batteries, this chapter deeply analyzes mostly used active materials of electrodes, used electrolytes and separators. Considering that the electrochemical principle of Li-S and Li-O batteries is different to Li-ion batteries, these accumulators of new generation are included in individual subhead. In the experimental part of this thesis are described methods used to measure electrochemical parameters of Li-S batteries. Next chapter contains description of preparing individual electrodes and their composition. Rest of the experimental part of my thesis is dedicated to the description of individual experiments and achieved results.

Blansko - a city barrier-free?
Cacková, Anna ; Tichý, Jan (referee) ; Pavlovský, Tomáš (advisor)
The content of the bachelor's thesis deals with the current state of specific sections using disabled people in the city of Blansko. The theoretical part of the thesis presents the city of Blansko, its surroundings and history. The next part is called barrier-free disabilities, where the individual categories of disabilities, the principles of movement and orientation, legislation in connection with disabled people, statistical data and elements of the barrier-free space are defined. The practical part expects the movement of blind people on selected routes. It evaluates the accessibility of buildings for blind people and opinions on other problem areas related to the movement of disabled people in selected sections.

An Analysis of Urban Amenities in Housing Estate Inner Courtyards in Bratislava
Demovičová, Tatiana ; Májek, Jan (referee) ; Tichý, Jan (advisor)
This bachelor thesis focuses on an analysis of urban amenities in inner courtyards of housing estates with a special focus on playgrounds. It includes a description of the history of housing estates in Bratislava and especially the Trávniky estate, which was further analysed. This estate is analysed from both a general perspective and urban composition. The theoretical part discusses the area of public amenities in general. The practical part includes a comprehensive analysis of selected courtyards with a focus on playgrounds and their user experience, amenities and security. Collected data were analysed and a simplified SWOT analysis created. For the most pressing issues, changes and possible improvements were proposed.

Effect of the pressure used in the manufacture of the electrodes on their final properties
Foltová, Anežka ; Tichý, Jiří (referee) ; Kazda, Tomáš (advisor)
The aim of this work is to describe final properties of the electrodes based on the amount of pressure used during its production. In the theoretical part of this work, secondary electrochemical accumulators are described, with the focus on Li-ion accumulators. In the main part of this work, the production of Li-ion accumulators, with usage of different pressures during its production is described. In the final part of this work, the examination of these created cells for the classification of the optimal production pressure is described.

MES/MOM Systems in the Industry 4.0 concept
Tichý, Jan ; Kaczmarczyk, Václav (referee) ; Pásek, Jan (advisor)
This diploma thesis "MES / MOM Systems in the Industry 4.0 concept" deals with the analysis, design and implementation of these systems. The first focus is on Industry 4.0 analysis, where are describe each part of Industry 4.0. Based on this knowledge, there were specified the changes in the MES / MOM systems. According to the changes and knowledge were designed and implemented the MES / MOM concept. The system communicates with the PLC using its own communicator and represents the data in the application environment. The application implements the Historian module and system modules. The PLC has an MS SQL protocol implemented so that the device can read and write data without the need to communicate with the parent system. This implementation is in line with Industry 4.0’s concept.

Photo Noise Reduction Using Deep Neural Networks
Tichý, Jonáš ; Juránek, Roman (referee) ; Španěl, Michal (advisor)
Obrazový šum je fundamentálním problémem v digitální fotografii. Cílem této práce je studium redukce šumu ve fotografiích pomocí hlubokých neuronových sítí. Dvě vybrané metody založené na hlubokých neuronových sítích, DnCNN a BRDNet, byly implementovány a jejich výkon byl změřen v několika experimentech. Kromě toho byl navržen a proveden experiment na uživatelích s cílem vyhodnotit vnímanou kvalitu obrazu širokou veřejností. Experimenty ukázaly, že zatímco obě metody dosahují výborných výsledků v metrikách, jako je PSNR a SSIM, vnímaná vizuální kvalita ne vždy koreluje s numerickými metrikami. Výsledky prezentované v této práci zdůrazňují důležitost vhodných trénovacích dat a metrik kvality obrazu v odšumování digitálních fotografií.

Chandigarh - Indian dream of the city
Spilková, Klára ; Tichý, Jan (referee) ; Pavlovský, Tomáš (advisor)
This Bachelor’s Thesis deals with the creation and development of the Indian city of Chandigarh, built on the green field. Its creation was necessitated by major political problems related to the establishment of India as a sovereign nation. The first part explains architectural and urban principles of the world-famous architect Le Corbusier, who was the author of the Master Plan of Chandigarh. Subsequently, the creation and development of Chandigarh is laid out, up to the present. The practical section compares Chandigarh with Amritsar, a traditional Indian city, followed by a study of the present state of selected city sectors, together with an analysis of the land use. The purpose of the Thesis is to present the problems of city construction on the green field, including an analysis of functionality. Given that there is as yet no Czech work dealing with the creation, development, and present state of Chandigarh in a similar extent, this work might be found useful.
