Simulation and optimization model of reservoir system in Svitava river basin
Šejnoha, Michal ; Marton, Daniel (referee) ; Menšík, Pavel (advisor)
The bachelor´s thesis is focused on the construction of a simulation and optimization model selected water management system. Both models are created with program SOMVS. The simulation model is based on the choice improved outflow from reservoir searching of boundaries Assurance classes. The simulation model simulates the flow of water through the system. Not finding the optimal solution using optimization methods. In the optimization model is used optimization method of differential evolution. The optimization model seeks maximized value of the objective function for water withdrawal from selected profile.

Numerical Analysis of Influence of Electromagnetic Fields on Small Airplanes
Řezníček, Zdeněk ; Hazdra,, Pavel (referee) ; Karban,, Pavel (referee) ; Raida, Zbyněk (advisor)
This thesis deals with numerical analyses of electromagnetic fields on small aircraft with composite parts as an innovative way for assessment of their inherent protection against electromagnetic effects of outside environment in all development stages. It is concentrated for procedures of creation of geometrically and materially complex models for simulating calculations in the time as well as frequency domains, execution of the simulations itself and comparisons of results between the internal electromagnetic calculations and executed experimental tests. Achieved results were verified on a simplified reference model of aircraft's fuselage and two aircraft prototypes VUT100 and EV-55 of the company Evektor, spol. s r. o.

Simulation and analysis of the block cipher mode with statistical self-synchronization
Kopčan, Marek ; Zezula, Radek (referee) ; Burda, Karel (advisor)
There is a enormous rise in importance of cryptography. In age of hi-technologies, where information are the most valuable asset, is need to protect this value. But we need to transport information between us and keep information confidental. In this case we use special modes of block cipher because of defect in communication canal. Not all modes are able to deal with this problem. For this purpose, there are special modes. This work deal with self-synchronization modes of block cipher. It is protection of tranfered information in communication canal against different types of defects. We will exam two self-synchronization modes - OCFB (Optimized Cipher FeedBack) and SCFB (Statistical Cipher FeedBack). Both have their advantages and disadvantages. The goal of this work is to provide analyse of both modes and to create simulation model. This model should help with further research of self-synchronization modes.

Jurák, Petr ; Staněk, Miroslav (referee) ; Polák, Ladislav (advisor)
This diploma thesis deals with the analysis of the IEEE 802.11ah wireless communication system. For such a purpose, an appropriate simulation model in program environment MATLAB is created. The first part of thesis focuses on the IEEE 802.11 standard. Basic blocks of the transmitter and receiver are described. Attention is also devoted on the brief description of considered transmission channels. The second part contains the description of the proposed and realized simulation model in MATLAB. Individual blocks of the simulation model are described in details. Finally, the obtained simulation results are evaluated and discussed.

Simulation model of reservoir system in Dyje river basin
Buršík, Lukáš ; Kozel, Tomáš (referee) ; Menšík, Pavel (advisor)
This Bachelor’s Thesis is focused on creating a simulation model of the reservoir system in Dyje river basin. The reservoir system consists of four reservoirs: Jevišovice and Výrovice on the Jevišovka River, Vranov and Znojmo on the Dyje River. The HEC-ResSim program was chosen to create the simulation model. The simulation model is aimed at reservoir storage function and the calculation works with the daily step. Real data of individual reservoirs and real flow series of three measuring profiles are used. The first part of work deals with simulation models and reservoir functions in general. Then the used program is described in a greater detail. The second part deals with selected system of reservoirs, watercourses and measuring profiles. There can be found a description of creating the model itself in the selected program in the third part. The description is complemented by selected examples of physical data and management rules. The last fourth part is devoted to a summary of the results, which are again accompanied by selected examples.

Design of Water Supply Facilities with the Support of Simulation Software
Pešout, Jakub ; Tauš, Miloslav (referee) ; Kučera, Tomáš (advisor)
The subject of the thesis is the design of water supply facilities with the support of a simulation software. The document is a summary of representative software tools that are used to design water supply sites directly or serve as supportive programs. A short summary of the origin, primary focus, availability and market price of each tool is listed in the survey. Furthermore the individual programs are divided into four groups. The section conveys the software's ability to deal with any of the following issues: - Water quality - Hydraulic analysis and simulation of hydraulic working - Design of water network - Creation of simulation models Subsequently, three chosen programs are subjected to exemplary tests, demonstrating some of the capabilities. The first program is Watpro, on which a design of a water treatment plant is drafted and a subsequent search for the sufficient dose of chemical additives is executed. The second program Epanet 2.0 calculates a model test of a water leak from a pipeline. The result is then compared with the outcome of equation calculation. The last program is Watdis, with which the same example of pipeline leakage is calculated and subsequently compared to the Epanet 2.0 result. The work's aim is to provide an overview of the seventeen selected programs and supply the information to potential users from the ranks of designers and students.
