The design Spice models OA with verification their accuracy
Kučera, Tomáš ; Drexler, Petr (referee) ; Roubal, Zdeněk (advisor)
This bachelor thesis describes the design macromodels of operational amplifiers on the 5th level. Macromodel is designed from the measured parameters of the integrated circuit and created first Boyleho model and later model of multiple pole/zero. The proposed circuits are created using the entire library program OrCAD PSpice. The created macromodel can enter certain common parameters and simulate the manufacturing tolerance and mark modeled to a limited extent, other types of OA. The measured parameters are compared with results of PSpice simulation program and verified the accuracy of the method used for the design macromodel. Models are also suitably modified to simulate the noise voltage.

Plan for drought and water scarcity
Bakota, Filip ; Coufal,, Marek (referee) ; Kučera, Tomáš (advisor)
The aim of the diploma thesis is to describe and prepare the pilot plan for drought and water scarcity for the selected locality, according to the prepared amendment of water law. Recent years have shown that drought will play a significant role in water supply in the future. Therefore, the need for tools to provide procedures and guidelines for individual administrations is more than important. The first part of the diploma thesis deals with issues of drought and water scarcity, climate change and prospects for the future. The next section describes a plan for drought and water scarcity. In the next parts of the diploma thesis, there are procedures that can mitigate or completely avoid the consequences of drought. From this informations, a pilot study of the plan for drought and water scarcity for the town of Počátky is being prepared in the next part.

Intelligent Editor for the AHLL Language
Kučera, Tomáš ; Rozman, Jaroslav (referee) ; Zbořil, František (advisor)
The subject of this bachelor's thesis is the design and implementation of an intelligent editor for the agent language AHLL. The reader is familiarized with the concept of agent systems and the WSageNt platform. Following is analysis and comparison of existing editors and integrated development environments. Presented will also be technologies ANTLR, RSyntaxTextArea and AutoComplete providing resources for effective implementation of some of the editor's key features. The resulting editor integrates existing AHLL to an ALLL compiler as well as the distributed system simulator T-Mass. Finally, we test the editor's ability to choose the best combination of compiler optimizations based on the target code's length.

Design and Operation of Water Disinfections Plants
Krupicová, Simona ; Rajnochová, Markéta (referee) ; Kučera, Tomáš (advisor)
In the first part of my bachelor thesis I deal with individual disinfectants used for hygienic supply of drinking water based on chlorine and without chlorine. Then I mention the operation without chlorine disinfectants. In the second part of this thesis I describe individual plants using various disinfection methods and at the end of the thesis I compare these methods and use it in practice.

Efficiency of Water Treatment Processes Using Activated Carbon
Hladíková, Lucie ; Kolesíková, Lucie (referee) ; Kučera, Tomáš (advisor)
The subject of the thesis is the issue of pesticides in the environment and the possibility of their removal through activated carbon. The thesis is divided into two parts, the search part and the practical part. The research part is focused on description of activated carbon. It also deals with the distribution of pesticides and their degradation in the environment. In the practical part, a laboratory experiment was carried out to determine the effectiveness of removing pesticides and metabolites from the test water on two types of activated carbon.

Using the tertiary degree for water treatment
Kovačíková, Kristýna ; Kučera, Tomáš (referee) ; Biela, Renata (advisor)
Bachelor thesis will deal with water treatment options with greater pollution, when it is necessary to include after the secondary degree even the tertiary degree. It will be create an overwiev of equipments, which are suitable under certain conditions as tertiary degree and will be worked out a study with using of this degree. As part of this work is to create an overview facilities that are suitable under certain conditions, such as tertiary degree and next a study of water treatment with the use of this degree. The study designed middle water treatment plant and two sedimentation tanks, four european and three active carbon filters.

Evaluation of the benefits of reconstruction at the water treatment plant
Zikudová, Markéta ; Nováková, Jana (referee) ; Kučera, Tomáš (advisor)
The subject of this bachelor thesis is a comparison and evaluation of the condition of the Nudvojovice water treatment plant before and after the reconstruction. The bachelor thesis gradually describes the basic concepts and general principles of treatment of raw water for drinking water. Specifically, the work describes the methods of raw water collection, technologies used in treatment plants, water quality indicators and types of water treatment plants. The work also describes in detail the Nudvojovice water treatment plant before reconstruction, which took place in 2018 and after. The work is mainly focused on the collection of raw water, changes in treatment technology and the quality of raw and treated water. The work also presents other than implemented solutions for drinking water treatment and then compares the status of the original and reconstructed water treatment plant in various respects.

Analysis of methods of measurement of fully-differential frequency filters
Kučera, Tomáš ; Kubánek, David (referee) ; Jeřábek, Jan (advisor)
This bachelor thesis focuses on measurements methods of differential frequency -selection filters with active elements in current mode. Firstly it describes differential frequency-selection filters in current mode and conversions from voltage to current mode. Next the thesis deals with measuring of particular voltage converters to differential current and back from differential current to voltage, which is an integral part for measurements of differential frequency-selection filters in current mode. For design of particular converters there was used program OrCAD there and subsequent simulation was executed in program PSpice.
