Autonomous cell "Ice cube feeder" for Industry 4.0 testbed
Mařas, Michael ; Kaczmarczyk, Václav (referee) ; Sýkora, Tomáš (advisor)
The bachelor's thesis deals with the description of the proposal and implementation of autonomous cells called Ice cube feeder. Gradually, we will learn how the implementation of autonomous cells in terms of design, electrical and programming. The concept represents the ideas of Industry 4.0. The entire production process follows the ANSI/ISA-S88 batch control standard, which describes the batch control process.

Autonomous liquid storage with cooling system
Boch, Jan ; Kaczmarczyk, Václav (referee) ; Husák, Michal (advisor)
This bachelor thesis deals with the design of an autonomous liquid storage cell with a cooling system. The cell is part of a larger project called the Self-Acting Barman. The cell follows the basic principles of Industry 4.0 and is also an example of a batch process according to the ANSI / ISA-S88 standard. At the beginning, the theoretical part describes important ideas and principles related to this project. The next chapter then discusses the construction design of the cell and its physical implementation. Parts were modeled in the Siemens NX program and subsequently these parts were created using 3D printing technology. In the next chapter the individual instrumentation used in the cell is described. In the last two chapters, the electrical connection of the whole cell and the software of the cell are then discussed. The cell wiring diagram is created in the E-Plan program and the cell software was created in the Siemens TIA Portal program.

Design and implementation of software for transportation entities of the Industry 4.0 testbed.
Sýkora, Tomáš ; Lázna, Tomáš (referee) ; Kaczmarczyk, Václav (advisor)
This diploma thesis deals with construction and software of transport entities for testbed Industry 4.0. The aim of the thesis is to create a transport network for moving a glass with a drink between individual cells on a production table. A four-axis Epson SCARA manipulator is used to transport the glass and a conveyor with carriages is designed to serving the finished drinks. The first part deals with the description of used components and their electrical connections. The second part describes the program solution of robotic manipulator and programmable logic controller. The final part is devoted to the description of problems arising during implementation.

Security and Performance Testbed for Simulation of Proof-of-Stake Protocols
Hud, Jakub ; Perešíni, Martin (referee) ; Homoliak, Ivan (advisor)
Tato práce se zabývá testováním výkonu a bezpečnosti konsensus protokolů typu Proof-of-Stake (PoS). Na teoretické úrovni porovnává protokoly ProPos, Algorand, Hedera, Ouroboros a Tezos z pohledu výkonu, možností útoků a obraně proti těmto útokům. Součástí práce je implementace simulačního frameworku v Omnet++ 5.4.1 pro provádění simulačních experimentů s protokoly ProPos, Algorand a Hedera. Simulace se zabývají zejména výkonem těchto protokolů. Na základě zjištěných výsledků jsou navržena určitá vylepšení.

BLDC motor control under load
Macháček, Jan ; Otava, Lukáš (referee) ; Pohl, Lukáš (advisor)
The bachelor thesis is focused on sensor control of BLDC motors by FOC (Field Oriented Control) method. In the first part of the thesis is the BLDC motor powered by ESC (electronic speed controller) by ST Microelectronics. In the second part is used own maked ESC. Both ESCs encompasses STM32F303 microcontroller specially fitted for BLDC motor control. In this thesis is used BLDC motor with twenty-two poles with inbuild magnetic rotary encoder. In the next part is described testbed for motor reaction torque testing during breaking in realation to connected load and load charakteristice is measured and listed. Reaction torque of motor is measured by sensor of mechanical stress. Furthermore is described function of active supply bus limiter.

Automatic testbed for opponent sensors of minisumo robots
Radvanský, Martin ; Kopečný, Lukáš (referee) ; Lázna, Tomáš (advisor)
Aim of this bachelor thesis is the design and creation of an automated testbed for measuring changes in the detection characteristics of IR sensors under the influence of external light interference. The measurement is performed in the simulation of daylight, artificial lighting and IR interference. Part of this work is the creation of a decision system for evaluating sensors depending on their properties, for use in minisumo competitions.

Security and Performance Testbed for Simulation of Proof-of-Stake Protocols
Kotráš, Jan ; Hellebrandt, Lukáš (referee) ; Malinka, Kamil (advisor)
Tato diplomová práce se zabývá technologii blockchain se zaměřením na konsenzus protokoly, zvláště protokoly typu proof-of-stake. V této práci naleznete popis těchto protokolů následovaný popisem konsenzu v technologii blockchain. Prvotní kapitoly detailněji popisují a porovnávají jednotlivé proof-of-stake protokoly na základě teoretických znalostí. Druhá část práce se zaobírá návrhem a implementací testbedu, který je následně použitý pro praktické porovnání proof-of-stake protokolů. V závěrečné částí práce je diskutováno nad zjištěnými výsledky pozorováním testbedu a zjištěnými vlatnostmi protokolů. Na tomto základě práce ve svém konci naznačuje další směřování consesus protokolů, ba jejich případné zlepšení, a zvláště proof-of-stake typu protokolů.

Identifying Anomalies in Industrial Networks: A Proposed Testbed for Experimental Evaluation
Kuchar, Karel ; Blazek, Petr
Not only because of the convergence of InformationTechnology (IT) and Operational Technology (OT) networks, thepass-through network environment needs to be monitored andadequate security implemented. Due to the occurrence of differenttypes of anomalies and their inconsistency in the literature,three main types of anomalies have been identified in this paperand a testbed has been proposed to serve for further experimentaltesting. This testbed was created using an anemometer and inthe current state using an accelerometer. From the results sofar, a correlation between the normal condition and the inducedoperational anomaly can be observed.
