Modern vibrodiagnostics of machines and evaluation of datasets by neural networks
Koníček, Tomáš ; Holoubek, Tomáš (referee) ; Hammer, Miloš (advisor)
This Master‘s thesis focuses on technical diagnostics with an emphasis on vibrodiagnostics of machines and equipment. The aim is to carry out research on vibration monitoring using modern on-line systems and to investigate the possibilities of processing the acquired data files using neural networks. Vibration monitoring from Siemens SIPLUS CMS is analyzed, including a description of individual hardware and software components. The work also focuses on machine diagnostics using a real model equipped with the SIPLUS CMS system in cooperation with the SIMATIC S7-1200 programmable automaton. The obtained data will be transferred via the FTP protocol for further processing in the Matlab program. Neural network models will be designed and used, which will be trained on the measured data. Convolutional neural network model will be used. The results will be evaluated and a conclusion will be drawn.
Automation tasks for education
Kouba, Martin ; Holoubek, Tomáš (referee) ; Dosoudilová, Monika (advisor)
This bachelor's thesis focuses on the creation of educational tasks of Automation. The thesis includes three main types of control: logical control, continuous control, and discrete control. Each type of control is described in a separate chapter with the basic theory, which is subsequently applied to sample examples including the solution process. For practice purposes, unsolved examples with solution results are provided at the end of each chapter
Cryo Tubes 2D Codes Scanner
Anděl, František ; Holoubek, Tomáš (referee) ; Matoušek, Radomil (advisor)
This bachelor’s thesis concerns the design and construction of a prototype two-dimensional code scanner placed at the bottom of cryotubes, which are stored in a cryogenic rack in the SBS (Society for Biomolecular Sciences) format. The theoretical section discusses the design and use of cryotubes, storage systems, and marking methods. It also describes the existing scanning methods, anti-fogging solutions, optical sensors, electromechanical elements and gears, microcontrollers, and single-board computers. The practical part of this thesis is devoted to the design of the mechanical structure and production of a prototype using 3D printing. This is followed by testing the functionality of the solution for collecting code images of sufficient quality and designing a solution for transferring the code image to the computer.

PetNetSim Library Computation Performace Optimization
Dražka, Vojtěch ; Holoubek, Tomáš (referee) ; Dobrovský, Ladislav (advisor)
The aim of the thesis was to optimize the computation speed of the PetNetSim library, which is currently implemented in Python. The purpose of the thesis was to approach the optimization from a broader perspective and try to speed up Python using various techniques. The thesis explores the solutions available in the form of alternative interpreters, extending modules, trans-compilation methods and the possibility of developing the computational core as a module written in the system language. The practical part describes efforts to implement these methods and their comparison. Furthermore, the multiprocessing method is implemented and the procedure for developing the computational core as an extending module is outlined.
