Pharmacokinetic modelling in Positron Emission Tomography
Čaňková, Lenka ; Jiřík, Radovan (referee) ; Mézl, Martin (advisor)
This bachelor thesis deals with pharmacokinetic compartmental modelling in positron emission tomography. It includes a description of the basic pharmacokinetic variables and models. Models for selected radiopharmaceuticals are theoretically developed. Simulations of different organs in the Simulink environment have been performed for the radiopharmaceutical 18F-FDG. A brain slice model for the radiopharmaceutical [11C]-PS13 was created. Estimation of constants and optimization of models based on real data was performed. Subsequently, graphs of radiopharmaceutical concentrations as a function of time were plotted and described.

Low Earth orbit trajectory prediction using a machine learning approach
Janda, Přemek ; Vlk, Jan (referee) ; Novák, Jiří (advisor)
Přesné orbitální predikce orbit satelitů na nízé oběžné dráze Země jsou nezbytné pro každodení provádění operací, tak aby se předešlo jejich srážkám. Tato práce se zaměřuje na analýzu histrorických dat trajektorií, tvořených z klacických dráhových elementů. S využitím strojového učení, data jsou sdružena, zpracována a na závěr užita pro predikci dráhy orbity. Nejlepších výsledků předpovědí bylo dosaženo s neuronovou sítí s doulodobou a krátkodobou pamětí (LSTM).

Sequence Diagram Generation from Object-Oriented Petri Nets
Bláha, Jiří ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
The goal of this bachelor's thesis is to design and create an application that graphically represents the communication between objects during a simulation of object oriented Petri nets (OOPN) as sequence diagrams. Input to the application is the definition of OOPN classes written in PNtalk. A simulation server, implemented in SmallTalk, is used for OOPN model simulation. This thesis describes server commanding and corresponding data retrieving as well as its transformation to a form suitable for sequence diagram generation and drawing. The implemented solution allows users to save the final sequence diagram as a PNG, SVG or XML file for further result sharing and processing. The application simplifies working with the simulation server, which otherwise doesn't incorporate any form of human-readable output and, therefore, it allows users to quickly and easily determine the order of events inside the simulated model.

Design of a reference luminaire
Cikryt, Adam ; Baxant, Petr (referee) ; Škoda, Jan (advisor)
The master's thesis deals with the design and manufacturing of a reference luminaire for use in lighting laboratories. In the design of the luminaire, simulations in Ansys Speos are used to assess the luminaire's lighting properties. The designed luminaire is manufactured using 3D printing and assembled. The light technical properties of the luminaire are determined by measurements in lighting laboratories.

An simulation of the robot in webots and ROS
Musílek, Miloš ; Lázna, Tomáš (referee) ; Burian, František (advisor)
This work deals with the creation of a simulated manipulator with six degrees of freedom. The thesis describes simulation tools webots and Gazebo and the ROS system. The practical part deals with the creation of a simulation with a robot model and a simple environment. Subsequently, the simulated robot is coupled with the ROS system to create a controller that mimics real manipulators. The result is shown by moving an object using a set of instructions.

Simulation of Perfusometric Data
Hývlová, Denisa ; Mézl, Martin (referee) ; Jiřík, Radovan (advisor)
This diploma thesis focused on the simulation of perfusion MRI data. The introduction describes standard perfusion imaging methods, DCE and DSC, and the quantitative analysis of perfusion. In the following section, simulation of the perfusion MRI data and the structure of the provided simulation software are described. This software was reworked, and new methods and parameters were implemented. The key product of this work is a simulation study of focused ultrasound-induced blood-brain barrier opening, comparing the pharmacokinetic models used in this application and the accuracy of their permeability estimates. The results of the simulation study were compared with real-dataset results.

Design of a photovoltaic power plant on an industrial building to reduce energy consumption
Pospíšil, Filip ; Vaněk, Jiří (referee) ; Jandová, Kristýna (advisor)
The master thesis addressed the issue of reducing energy demand. The aim was to design a photovoltaic power plant for an industrial building, which will reduce this energy consumption. During the work, several simulations of different proposed photovoltaic systems were created and compared with each other, and the most suitable design was selected based on the input aspects. The theoretical background of the thesis has been used, which is described in the first two chapters. The thesis is supplemented by the calculation of the energy performance of the building, the project documentation of the chosen design and the analysis of the possibilities of how the surplus energy produced by the photovoltaic power plant can be utilised. Subsequently, an evaluation and conclusion are made.

Testbed for Simulation of MCU Application using RTL Environment
Ohnút, Petr ; Burian, František (referee) ; Arm, Jakub (advisor)
The thesis is focused on creating a test framework for easy simulation and configuration of mcu applications. The framework also provides basic processing of simulation output data, such as measuring UART or SPI communication speed, checking the expected instruction with the currently executed one, counting the executed individual instructions during the simulation, etc. Test scenarios are designed to simulate the implemented functionalities of the framework. Finally, the results of each test scenario are discussed.

Control and visualisation of a virtual production line
Viater, Dominik ; Jirgl, Miroslav (referee) ; Štohl, Radek (advisor)
This thesis focuses on the control of a virtual production line using FACTORY I/O and PLC. The introduction of the thesis is devoted to the description of the FACTORY I/O program and its scene editing and part manipulation capabilities. It then discusses the design and implementation of a virtual production line, for which PLC control software and HMI panel visualization were developed. The aim of the thesis is to provide a tool to better understand and control PLCs through virtual production lines.

Optimization of electrostatic simulation by utilization of distribution equations with emphasis on design of capacitance sensors of inhomogeneity distance
Mancl, V. ; Beneš, P.
This paper deals with the problem of optimizing the simulation of electrostatic fields with a focus on electrode setup simulations for capacitive sensor design. Several simulations were performed in Ansys electronics desktop software in Maxwell 2D and 3D module. The simulations were carried out on a sensor model with parallel plates, between which the movable inhomogeneity was placed. In the simulation, the inhomogeneity was modeled as an solid object. The proposed optimization consisted in replacing the inhomogeneity as an object by the equation of permittivity distribution in the space between the plates of the capacitor. The obtained dependences of the capacitance on the position of the inhomogeneity of the two models were compared together. Also the time required to complete the simulation was discussed. In addition to evaluating the advantages and disadvantages of the two modelling approaches, the paper describes a method for simulating a continuous gradient distribution of inhomogeneity permittivity.
