Assessment of the water flow in the Vltava river basin
Černý, David ; Duchan, David (referee) ; Uhmannová, Hana (advisor)
The bachelor´s thesis includes the assessment of the current state of the channel Drnový potok as well as the objects in the solved section from river km 5,972 to river km 7,021. The 1D mathematical model HEC-RAS version 4.1.0 is used for the calculation of the course of level and for the assessment of the channel capacity, including the objects connected to it. The work also deals with the ideological proposal of near natural flood protection measures in the municipality of the village Luby on the design discharge Qn = Q20 = 51,80 m3/s.

Proposal of measures on Svratka river in the cadastral area of Svratka
Černý, David ; Vysloužilová, Lucie (referee) ; Uhmannová, Hana (advisor)
The diploma thesis focuses on the assessment of the current state of the Svratka watercourse and of the capacity of the existing objects on the course, which is partially modified in the solved locality and includes both – intravarian and extravarian areas of the town. Within hydrotechnical calculations, the 1D mathematical model HEC-RAS version 5.0.6 was used to determine the course of levels. The thesis focuses also on suitable design of flood protection measures on the river Svratka with protection for design flow Qn = Q20 = 28,6 m3 / s.

Detached house
Černý, Dávid ; Majsniar, Michal (referee) ; Kolář, Radim (advisor)
The subject of this bachelors thesis was to design a single-family house in Brno Mokrá Hora and process the study and the design documentation for this house. Part of it will serve as permanent housing for a 4 member family and the second part as a distribution point for an online shop with 2 employees. The walls will consist of sand-lime bricks with an additional contact thermal insulation system ETICS, the ceiling will be reinforced concrete constructions and the house will have a walkable flat green roof. Part of the documentation is also the modification design of the surrounding terrain and the design of the car park for 2 cars and 1 light commercial vehicle. An interesting design choice is the height level of the roof, which is situated in the same level as the local road. Design documentation was processed using the program AutoCAD, the study and the visualization using both ArchiCAD and Artlantis 5.

Ultrasound Simulation in Python
Černý, David ; Olšák, Ondřej (referee) ; Jaroš, Jiří (advisor)
k-Wave je MATLAB nástroj pro simulaci šíření zvukových vln. Cílem této práce je reimplementovat část nástroje k-Wave v jazyce Python se zaměřením na výpočetní výkon. Druhým cílem je formulace sady doporučení pro transformaci zdrojových kódu z jazyka MATLAB do jazyka Python, které by mohly přispět při dalším vývoji. Tato práce nejprve shrnuje klíčové funkce nástroje k-Wave, zkoumá technologie pro vysoce výkonné výpočty dostupné v jazyce Python a zdůrazňuje nejzásadnější aspekty transformace zdrojových kódů z jazyka MATLAB do jazyka Python. Druhá část práce se zabývá architekturou, testováním a měřením výkonu výsledné Python implementace. Výsledkem této práce je implementace trojrozměrné simulace šíření zvuku, která je kompatibilní s k-Wave. Nová implementace vylepšuje strukturu původního nástroje a poskytuje výkon srovnatelný s původním nástrojem, v určitých případech výkon původního balíku převyšuje.

Hotel "U Prehrady"
Černý, Dávid ; Nováková, Eva (referee) ; Kolář, Radim (advisor)
The subject of this diploma thesis was to process the study and the design documentation for a newly built hotel in Brno, in city district “Kníničky” near the artificial dam “Přehrada” in a rest area. The hotel will serve as temporary accommodation for up to 64 hotel guests in single, double and four bed rooms. The object also contains training rooms, offices, a meeting room, a café, a small grocery store and a restaurant with kitchen. Parking is possible in one of the two mass garages and there is an outdoor parking possibility in front of the hotel too. The building has a cast-in-place concrete frame with longitudinal beams and sway bracings. The external wall consists of aerated concrete bricks with contact thermal insulation system ETICS (insulation material mineral wool), the ceilings will be cast-in-place reinforced concrete ceilings and the roof flat green roof or flat roof with gravel on it above the 5th floor. The foundation construction consists of reinforced concrete foundation strips, which expand to foundation pads under the load-bearing columns and will be supported by piled foundations under the most exposed elements. As long as the hotel is situated into a fairly steep slope, the vertical alignment of some building parts is various so part of the project is the design of landscaping works. Design documentation was processed using the program AutoCAD 2017, the study and the visualization using both SketchUp 2015, LayOut 2015 and Lumion 5.

Difference between electronic signature standards before and after the introduction of eIDAS.
Černý, David ; Novotná, Jitka (advisor) ; Dvořák, Jan (referee)
The work compares the differences in the use of the Czech electronic signature before and after the implementation of the regulation of the European Parliament and Council, which introduced the European standard for electronic communication eIDAS (electronic IDentification, Authentication and trust Services). Based on the research from available sources, the theoretical part of the work describes the legislative regulation of both systems, their ways of functioning and examples of use. The practical part contains a qualitative study in the field of electronic signatures and a description of the implementation of the eIDAS regulation in the Czech Republic, including case studies.

Impact of total transaction fees on the price of Bitcoin and Ethereum
Černý, David ; Krištoufek, Ladislav (advisor) ; Hronec, Martin (referee)
The aim of this thesis is to explore the price dynamics of Bitcoin and Ethereum with special emphasis on the role of transaction fees, which can provide insight into network congestion and user behaviour, and may also reflect the future economic viability of these networks. Previous research has shown intertwin- ing relationships between variables and suggested possible endogeneity in a cryptoasset environment. For these purposes, a system of two simultaneous equations for transaction fees and price was developed and subsequently esti- mated using the 2SLS method. The analysis covers relationships from both long-term and short-term perspectives. It turns out that the price dynamics of both assets is determined by a diverse mix of fundamental, economic and spec- ulative factors, despite the narrative that the price of cryptoassets is primarily driven by speculative factors. Furthermore, in the context of the fee-price re- lationship, it turned out that the relationship is a priori that the price impacts the fees, however, at some intervals, the opposite relationship is also shown, which is rather an exception. An important contribution could be the finding of a stable positive effect of the total number of active addresses in Bitcoin on transaction fees, which might bring new insights to the...

Sentience as criterion of moral status
Milko, Michal ; Černý, David (advisor) ; Jirsa, Jakub (referee) ; Gluchman, Vasil (referee)
Abstract. This dissertation suggests that sentience represents a plausible criterion of moral status. Sentient beings capable of having pleasant or unpleasant experiences have an inherent interest in not suffering by virtue of this capacity, and humans as moral actors commonly assume that it is wrong to inflict pain without a good reason. The first part of the dissertation aims to uphold the following three theses: 1) Biological life represents a too broad criterion of moral status; 2) Rationality (reason, language, moral autonomy, ability to reciprocate) represents a too narrow criterion of moral status; 3) Sentience constitutes a plausible criterion of moral status. The text presents the ethical theories of Albert Schweitzer, René Descartes, Immanuel Kant and Peter Carruthers. It unfolds the argument from marginal cases and the critique of speciesism. It focuses on basic concepts of consciousness, the issue of subjective character of consciousness, and the problem of other minds. It also reviews the existing scientific evidence of sentience in mammals, birds, reptiles, amphibians, fish, cephalopods, and arthropods. The second part of the dissertation aims to present and evaluate normative theories that address the criterion of sentience. At the same time, it aims to defend the thesis that contractualism,...
