The Monte Carlo Stochastic Method for Price Simulation
MÜLLEROVÁ, Sindy
This bachelor thesis focuses on predicting gold prices using the Monte Carlo model and utilizes data obtained from Yahoo Finance. The data used for the simulation covers the period from 2000 to 2023. Based on this data, values for the next 3 years are simulated. The prediction model provides optimistic, neutral, and pessimistic scenarios of future price development, represented by the upper quartile, median, and lower quartile. The findings show that in the optimistic scenario (upper quartile), gold prices continue to rise, indicating a consistently strong market trend. In contrast, the pessimistic scenario (lower quartile) indicates only a slight decline in prices, suggesting price stability. The neutral scenario (median) shows a slightly rising trend, ensuring that the value of the initial investment is preserved. The analysis carried out in this paper assesses the profitability of gold investment mainly due to the positive and stable price trend and offers valuable insights for investment decision-making.

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 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.

Implementation of a Multipurpose Measurement System for (Sub)Terahertz Electron Spin Resonance Spectroscopy
Šedivý, Matúš ; Malik, Aamir Saeed (referee) ; Epel, Boris (referee) ; Vrba, Radimír (advisor)
Spektroskopie elektronové spinové rezonance (také nazývaná elektronová paramagnetická rezonance nebo jen EPR) zahrnuje metody, které zkoumají hmotu prostřednictvím nepárových elektronů. Jednou z progresivních metod EPR je rychlé skenování, které umožňuje pozorovat kinetiku chemických reakcí. Kromě toho nedávný vývoj vysokofrekvenčních součástkách rozšířil použití vysokofrekvenční EPR (HFEPR), které využívají sub-terahertzové až terahertzové vlny. Tato práce se zabývá propojením obou cest do HFEPR spektrometru s rychlým skenováním frekvencí (FRaScan), který byl nedávno vyvinut na CEITEC VUT. Na začátku je stručně uvedena základní teorie k EPR, následovaný přehledem přístrojového vybavení pro HFEPR. V praktické části je popsáno technické řešení spektrometru. Důraz je kladen na implementaci softwaru, pomocí kterého je spektrometr ovládán a měření jsou automatizována. Následně jsou ukázány příklady z měření pevných látek, konkrétně karbidu křemíku dopovaného vanadem (SiC:V), ftalocyaninu líthia (LiPc) a krystalu 1,3-bisdifenylen-2-fenylallylu (BDPA). Příklady demonstrují schopnosti spektrometru získat multifrekvenční vlnově spojitá EPR spektra a frekvenčně rozmítaná spektra v závislosti na teplotě a orientaci vzorku, a taky spektra pomocí rychlého skenování frekvencí

Computer modelling of the movement of agricultural machinery during field
FILIP, Martin
This dissertation deals with the problem of optimizing the number of hauling trailers and loaders in the handling, collection and transport of bales of fodder or straw from the land to the storage site in order to achieve the lowest possible consumption of human labour. The automated decision-making process allows the optimum number of removal trailers and loaders to be selected s that there is no unnecessary downtime for the handling equipment while waiting for the transport equipment or, conversely, no lost time for the removal trailers due to insufficient loader capacity. The basic function of the optimization program is to process a Google Maps image of a real plot of land, detect its boundaries and, on the basis of estimates of forage or straw yields, estimate the approximate distribution of predefined bale sizes and determine the centroids, i.e. the locations where the hauler should be positioned when loading.The centroid is also the point from which the shortest travel distances for the loader are obtained. The centroids are assigned successively to the packages with the lowest distance until the group is full. This is the condition where the number of bales in the group corresponds to the transport capacity of the conveyor. Another function of the optimization algorithm is to schedule the travel routes in the centroid and based on the input value of the average speed of the loader, the time required for the travel of this machine is calculated. To the total working time of the loader is added the time required for driving from the storage area of the machine to the plot, as well as the time required for driving from the point of entry to the working area to the centroid, and the driving time from the processed centroid to the other centroids, including the driving time from the harvested areas back to the place where the loader will be parked. In addition, the value of the time required to lift all bales in the centroids and place them on the conveyor and the downtime of the manipulator are added to the loader's travel time to obtain the loader's total time. The working time of the removal trains is calculated from the distance of the route (multiplied by the average speed of these machines) from the storage location of the machines to the centroid, the loading time and the time required to travel to the storage location of the bales, including the time required to remove the bales from the removal trains. The time of the loaders and the removal trains is evaluated simultaneously, in synchronisation, and it is calculated whether there are any lost times, which are added successively to the working times. The optimization program sequentially calculates the different variants for (n) loaders, (n) transfer sets, evaluates which variant consumes the least time and is therefore optimal in terms of the lowest time consumption.
