Effectiveness of activated carbon in removing pharmaceuticals from water
Kučera, Jakub ; Lukášová, Daniela (referee) ; Biela, Renata (advisor)
The bachelor thesis deals with micropollutants in drinking water sources, specifically pharmaceuticals and the possibilities of their removal from drinking water. The theoretical part describes the possible pathways for the supply of pharmaceuticals to water sources, the most common types of pharmaceuticals found in water sources and the options for their removal. The practical part of the bachelor thesis is devoted to the concentrations of pharmaceuticals in raw water taken for drinking purposes and comparison of the properties of original and new activated carbon in their removal. Finally, the removal efficiency of selected quality parameters is compared.

Optimization of DDoS Attack Mitigation based on Machine Learning
Banák, Filip ; Šišmiš, Lukáš (referee) ; Kučera, Jan (advisor)
Útoky DDoS, ktoré využívajú protokol TCP patria stále medzi tie najbežnejšie. Táto práca cieli zlepšiť úspešnosť detekcie DDoS útokov využitím informácií dostupných v TCP SYN správach. Odtlačky TCP SYN správ sú navrhnuté ako dodatočný zdroj dát pri počítaní charakteristík na vyhodnotie prítomnosti DDoS útoku. Kombinácia existujúceho systému na extrakciu a agregáciu charakteristík s existujúcim detektorom anomálií založeným na autokodéroch je zoptimalizovaná a rozšírená na využitie SYN odtlačkov. Experimentálne výsledky ukazujú obstojné zlepšenie detekcie DDoS útokov na relevantných dátových sadách. Detektor sa trénuje a testuje respektívne 16-krát a 95-krát rýchlejšie. Systém na extrakciu a agregáciu je 23-krát rýchlejší.

Prostředí pro testování algoritmů potlačení útoků DDoS
Patová, Pavlína ; Šišmiš, Lukáš (referee) ; Kučera, Jan (advisor)
The work is focused on creating a test environment for simulating DoS attacks. This environment is useful for verifying the vulnerability of networks and services against the phenomenon of DDoS attacks, therefore it will be used to test the tools and techniques developed to defend against DDoS attacks. The outputs of these experiments can then be used as recommendations for network administrators to help improve the refensibility of their systems. The resulting tool is implemented in Python using the PyTest module. We were able to implement many of today’s most common DoS attacks, such as floods and amplification attacks. It is thus possible to test services against these most serious DDoS threats. The resulting tool is easily extensible to other methodologies or attack types, so it can also be used for emerging DoS attacks in the future.

Design, Creation and Implementation of Software Applications in the Corporate Environment
Kučera, Ján ; Koch, Miloš (referee) ; Novák, Lukáš (advisor)
Aim of this thesis is to design and implement a backend for internal web application that will be responsible for the aggregation of statistics and visualization of given statistics. The outcome of this thesis will also be executable as a stand-alone script for specific data. Outputs of said web application are going to help upper management with decision-making in the area of online gambling games, especially their development, modification, and modernization. This thesis will evaluate design, implementation and economic value of the given web application for the company in comparison to alternatives.

Exotarium ZOO Brno
Kučera, Jiljí ; Wittmann, Maxmilian (referee) ; Šindlar, Jiljí (advisor)
The topic of the bachelor thesis is the design of a pavilion for the Australia - New Guinea exhibition in Brno Zoo. The building serves mainly as an exposition and home for exotic species of birds, small mammals and fish. The building should meet all the conditions of buildings for the public, working conditions for employees and animal welfare. The area under consideration is located in the premises of the Brno Zoo, in the northern part of the district of Bystrc. The construction site is located roughly in the middle of the zoo at the crossroads between the Tropical Pavilion and the African Village. The relatively sloping, irregular plot is accessible from the north and east sides by a campus road. The kangaroo enclosure is directly adjacent to the west side, while the bison and camel enclosures are located to the north, across the road. The resulting design consists of a two-storey building that follows the contour line of the site. It is a building composed of two regular masses of rectangular plan. The upper smaller mass is superimposed on the lower larger mass. The pavilion includes indoor and outdoor aviaries, terrariums, aquariums, staff facilities, animal facilities and food preparation. The facade of the Exotarium imitates the red rock typical of Australia. It is made up of an ETICS system to which a moulded polystyrene layer and a painted surface will be added. An extensive green roof with aviaries is proposed on the main building. The design includes a small plaza to provide shade for visitors. Two buildings are proposed within the square - refreshments and public toilets. The bachelor thesis is based on documents in the form of assignment, dwg drawing of the cadastral situation and architectural study from the course BGA036 - Architectural Atelier 5.

The MDSR Vegetation Filter
Kučera, Jakub
This paper deals with the software implementation of a vegetation filter using the MDSR algorithm and its subsequent testing on a variety of pre-selected point clouds. The results of each filtering algorithm were compared visually in sections with the results of other conventionally used filtering algorithms. Comparisons were also made by calculating the root mean square deviations of the results of the conventional algorithms from the TIN surface generated from the MDSR filter results.

The analysis of Cu-Sn-Sb ternary alloy
Kučera, Jan ; Doubrava, Marek (referee) ; Jan, Vít (advisor)
This bacholor thesis deals with substituting silver-based material, currently used for experimental semi-liquid extrusion. The proposed material is from the Cu-Sb-Sn system. The theoretical part of the work deals with soldering and phase diagrams. The experimental part is devoted to the analysis of three proposed alloys from the Cu-Sb-Sn system, their structural and mechanical properties. Thermal analyzes of the alloys were performed using differential scanning calorimetry (DSC), the microstructure using a light microscope and a scanning electron microscope, and a hardness tester was also used to determine the hardness. The results are summarized in the discussion.

Modeling of solar power station parameters in GIS
Kučera, Josef ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
The work deals with the modeling of the parameters of solar power plants and the issue of solar energy with its use in the photovoltaic power plants. It uses the geographic information system named ArcGIS. In the beginning of the work, there is the theory. This theory is necessary to understanding the function of the photovoltaic cells, from the beginning to the photovoltaic panels construction. There were analyzed the conditions of the location of the photovoltaic panels in the Czech Republic. Furthermore, the work approaches the ArcGIS and its 3D modeling possibilities. The part of the work deals with the proposal for the selection process of the most suitable location to the photovoltaic panels installing. The main part of the work is the visualization of the 3D models of the locations of interest.

Technology to remove nitrogen oxides (NOx) from flue gases for large combustion plants
Kučera, Jan ; Brummer, Vladimír (referee) ; Jecha, David (advisor)
This diploma thesis deals with selected abatement techniques of nitrogen oxides (NOx) developed for large combustion plants. The first part describes selected NOx, their properties and explains the formation during combustion. Furthermore, there is an analysis of current legal legislation regulating the issue of emission limits. The third part presents selected primary and secondary measures that are widely used. The emphasis is placed on the description of selective catalytic (SCR) and non-catalytic reduction (SNCR). Finally, the basic design of these technologies for model combustion equipment is performed. The consumption of reducing medium and the volume of the catalyst for the mentioned techniques are calculated here. The estimate of selected operating and investment costs is a part of the basic scheme.
