Hybrid motorcycles represent opportunity in reducing fuel consumption and emissions of motorcycles, but also in increasing overall performance parameters while preserving the original propulsion unit. The thesis deals with the design solution of a hybrid motorcycle and its simulation in various operating modes. The model is compared to a conventional motorcycle model, and the differences between both concepts are observed. Simulations have shown higher acceleration and lower fuel consumption in the hybrid concept for most tests, except for highway traffic. The largest difference in fuel consumption of hybrid motorcycle was evident in urban traffic, where the use of a hybrid motorcycle proved to be suitable.

Paint shop Process Improvement through Predictive Simulation
Machačová, Simona ; Hromková, Ivana (referee) ; Videcká, Zdeňka (advisor)
This thesis focuses on the use of simulation to optimise processes in a paint shop. The aim of the thesis is to analyse the existing production processes and suggest improvements using simulation. In the analytical part of the thesis, the processes in the paint shop are described in detail and Petri nets are used to describe the logic of the processes in the paint shop. In the design part of the thesis, the problem and objectives are formulated, and the design of the simulation model is presented. The design describes the elements and methods used in the Plant Simulation software in which the model is created. Furthermore, different scenarios are simulated to optimize the painting process and the deposition areas. The simulation results are compared with the actual state of the paint shop. Finally, the results are discussed and recommendations are proposed to optimize the paint shop processes using simulation. This work presents new approaches to process optimization in industrial manufacturing.

Simulation of Spread of Infectious Diseases in Human Population
Křištof, Jiří ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The aim of this work is to develop an epidemiological model to simulate the spread of the infectious disease covid-19. The developed SVLIHDRS model builds on compartmental models and is implemented as a Markov chain with continuous time. For the implementation, the UPPAAL tool is used. By comparing the simulation outputs with the observed data, the Spearman coefficients are 0.8940 for infectious individuals and 0.9987 for deceased individuals, the mean bias errors are 12510.7285 and 316.2697, respectively. The results of this thesis are useful for making long-term predictions of the epidemic evolution of covid-19 infection.

Modelování chodicích robotů s pasivní dynamikou
Cvik, Dominik ; Hrabec, Jakub (referee) ; Grepl, Robert (advisor)
The presented bachelor's thesis deals with the creation of a model for a passive dynamic walking robot. The research part of the thesis describes the classification of two-dimensional robot designs with passive dynamics, along with a description of selected existing physical implementations of such designs. Equations of motion for the synthetic wheel design are derived analytically in the next chapter. These derived equations of motion are used to obtain initial values of variables, which will later be substituted in the simulation of the same model in Simscape Multibody. These obtained initial values are also substituted into the solution of the equations of motion. A comparison of the state variable time progressions obtained from the simulation and the analytical calculation shows a high agreement between these approaches, with only minor deviations, which are explained by the simplifying assumptions used in the analytical calculation.

Simulation of Spread of Infectious Diseases in Human Population
Vaňo, Michal ; Peringer, Petr (referee) ; Strnadel, Josef (advisor)
Epidémie predstavujú trvalú hrozbu pre život a ekonomiku krajín. Napriek ich ničivému potenciálu, ich dopad je možné zjemniť študovaním chorôb, ktoré tieto epidémie spôsobujúu, a predpoveďou ich dosahu. Modelovanie epidémií je kľúčové pre pochopenie šírenia infekčných chorôb a hodnotenie účinnosti zdravotných zásahov. Táto bakalárska práca najprv predstavuje a porovnáva kompartmentálne a multiagentné modely, dva primárne prístupy v oblasti epidemiologického modelovania. Zvoleným prístupom pre túto prácu je multiagentné modelovanie, ktoré bolo dôkladne analyzované a následne transformované na abstraktný model šírenia chorôb. Model je navrhnutý tak, aby bol spustiteľný na akomkoľvek slovenskom meste a poskytol všestranný nástroj na pochopenie dynamiky chorôb v rôznych lokalitách. Abstraktný model bol implementovaný v Pythone. Záverečná časť práce pozostáva z vykonania experimentov na analýzu rôznych scenárov a rôznych opatrení. Tieto experimenty prispievajú k hlbšiemu pochopeniu dynamiky šírenia chorôb a môžu byť zdrojom informácií pri tvorbe politiky v oblasti verejného zdravia. Práca ponúka prehľadnú štúdiu rôznych prístupov k modelovaniu a vyvíja všestranný model založený na agentoch, ktorý je možné rozšíriť podľa dostupných údajov.

Radar Interface and Its Interconnection to Air Traffic Control System Simulation
Buchníčková, Tereza ; Ondřej, Karel (referee) ; Smrž, Pavel (advisor)
This thesis aims to create an application for training new air traffic control officers. The system is implemented as a JavaScript web application using the JQuery and Leaflet libraries. The server part is written in Python using the BlueSky library for air traffic simulation. The thesis presents a theoretical background and discussed the design and implementation of the system. The result is an application that offers to display current air traffic, or where the user, in the role of air traffic control officer, can practice communication with a pilot on simulated air traffic. The application allows the recording of voice communication and, in cooperation with an automatic speech recognition system, converts this communication into text displayed on the screen. In addition to the support of the training of air traffic operators, this application also serves as a demonstration of the results of the research groups KnoT and Speech from the Faculty of Information Technology, Brno University of Technology.

Efficient Reduction of Finite Automata
Molnárová, Veronika ; Havlena, Vojtěch (referee) ; Lengál, Ondřej (advisor)
Konečný stavový automat je matematický model popisujúci stroj vykonávajúci výpočet na zadanom vstupe cez postupnosť stavov. Za posledné storočie si tento koncept našiel využitie v rôznych odvetviach informatiky od správania postáv vo videohrách po kompilátory. Pokým automat popisuje jeden jazyk, ten môže byť reprezentovaný nekonečným množstvom rôznych automatov. Keďže veľkosť týchto automatov sa líši, pre zaistenie čo najefektívnejšej práce chceme nájsť ten najmenší z nich. V tejto práci sa pozrieme na päť rôznych typov redukcie automatov. Najskôr sa budeme zaoberať troma známymi redukčnými algoritmami, menovite to bude minimalizácia deterministického automatu, redukcia pomocou relácie simuláciu a redukcia pomocou prevodu na kanonický reziduálny automat. Tieto redukcie boli implementované v jazyku C++ a otestované na skúšobnom vzorku automatov pre porovnanie výsledkov jednotlivých redukcií. Posledne sme sa pozreli na možnosť redukovať konečný stavový automat pomocou SAT a QBF solverov. Vytvorili sme množinu pravidiel pre každý solver pre tvorbu klauzule v konjunktnej normálnej forme, ktorá dokáže jednoznačne reprezentovať automat v Booleovej algebre. S využitím tohto faktu sme vytvorili nový spôsob redukcie nedeterministického automatu.

Simulation of Autonomous Mobile Robots
Janoušek, Radim ; Burian, František (referee) ; Lázna, Tomáš (advisor)
The goal of this work is to implement robotic algorithms for autonomous tasks. The thesis starts with an introduction to the ROS 2 framework, where the basic features of this framework are introduced. This is followed by a comparison of the most popular robotic simulators, including a more detailed description of the Gazebo simulator and the lesser known Webots simulator. The next chapter focuses on the reasons for choosing the Webots simulator for creating the simulated world and describes the process of creating the interior based on the template. The penultimate chapter discusses the creation of robotic platforms in the Webots simulator and the sensors used, including the simulated lidar. In this simulation, the lidar is created with a mock-up of the real device. In the last chapter, the drivers for controlling the robotic platforms are implemented and a package for ROS 2 is created.
