Methodology of identification of revisions and inspections of technical equipment for a manufacturing company based on the requirements of ISO 45001
Valenta, Jakub ; Jandová, Kristýna (referee) ; Bača, Petr (advisor)
This work deals with the issue of inspections and revisions of technical equipment according to safe operation standards on the basis of OSH and FP requirements. In the introduction, these fields of work safety and fire protection are described, which will be used in later parts of the work. Subsequently, the term „technical equipment“ and subcategories of this issue are defined, with each of the subcategories being specifically approached. As a result, the thesis describes why it is necessary to regularly inspect the technical equipment, while the individual types of inspections are subsequently defined. This is accompanied by the distribution of the person’s rights to carry out individual inspections and the distribution of responsibility for the inspections carried out. The acquired knowledge is then used to create a model of the process of regulation of inspections and revisions and to create an overview of periodic inspections and revisions of technical equipment for a manufacturing company. This model and review of inspections are then considered the output of this bachelor’s thesis.
Application for Real-Time Dual-Channel Analysis of Electroacoustic System

Master’s thesis contains the theory for realization of the researched software. Besides other, it describes Fourier transform, frequency response function, coherence, impulse response and group delay. Real life application of the software is discussed. Software is invented in the MatLab environment. Further, thesis provides testing of the software and shows its commented outcomes.
Preparation of laboratory exercise for school subject Ecology in Manufacturing
Balcárková, Lucie ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
The thesis deals with the design of laboratory task on selected topics and brings together theoretical knowledge needed to understand the principle and function of the proposed system. The theoretical design is elaborated from the point of view of physical principles, physical feasibility, electronic difficulty, user service, correctness of the system, and its economic aspect. Furthermore, the practical implementation of the chosen task is disscussed in detail, based on the collected theoretical knowledge, a comparison of the available options and the results of the measurements made.
Electrochemical Properties of Lithium-Ion battery under Elevated Temperature
Kulíková, Barbora ; Chladil, Ladislav (referee) ; Bača, Petr (advisor)
This Master’s thesis deals with a monitoring of the temperature influence on Li-ion batteries, literature search of this topic and proposal of experiments. First chapter contains the theory of evolution and fundamentals of the Li-ion batteries. Planned experiments with flow charts and block diagrams are described in the second chapter. The work station is explained along with a description of the execution of the experiments in the third chapter. The experiments are analyzed and results explained in the last chapter.
Monitoring of temperature influence on properties of lead-acid accumulators
Musil, Petr ; Křivík, Petr (referee) ; Bača, Petr (advisor)
This thesis deals with lead-acid battery, its parameters and temperature behaviour of this electro-chemical source of power. In the theory section, types of batteries are presented, followed by their primary parameters and electro-chemical reactions, which take part in battery cells. This section also contains information about charging stages, detailed description of each battery part, used materials, construction of the battery and degradation processes caused by battery operation. The practictal section of this thesis offers a measurement scheme for automated measuring workstation. Furthermore, the practical section presents results of measurements on parameters of chosen lead-acid battery types, it also contains long-term deep battery cycling and measurements under elevated temperatures. Detailed comparison of measurements results and datasheet values is included. Conclusion sums up parameters of chosen lead-acid battery types and their feasibility for further usage in power backuping.
Observation of lead electrode surface by atomic force microscope AFM
Bouška, Marek ; Máca, Josef (referee) ; Bača, Petr (advisor)
This master's thesis is focused on in situ observation of the negative electrode of the lead acid accumulator using atomic force microscopy AFM. Discussed topics are lead acid accumulator, atomic force microscopy, cyclic voltammetry and current knowledge of the in situ observation of the lead acid accumulator using AFM. The main task of this project is assembling the experimental cells, make in situ observation of the negative electrode surface of the lead acid accumulator. In the end evaluate if this method is suitable for the lead acid battery observation.
Determination of emissions and harmful particles of exhaust gases of CNG, petrol and diesel vehicles
Rozsíval, Adam ; Libich, Jiří (referee) ; Bača, Petr (advisor)
The thesis deals with an analyses of emission and harmful particles of exhaust fumes of automobiles with an environmental impact. More precisely, it describes the basic characteristics of current fuel types and emission produced by internal combustion engines. Next, it deals with the measures and possibilities of decreasing car traffic emission with respect to environmental impact. It also describes the current European standards for emission and the systems of the cars that are able to decrease emission. The work also deals with the measuring of emission and the methods that are used. According to the measuring methods, the analysis of exhalation is done and it is based on the data of the real car fleet. Values of the emission analyses are compared. The financial aspect is a part of the analyses.
Preparation of a laboratory assignment for the Ecology of production subject
Dovčík, František ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
The thesis deals with the quality of water in general as well as from the perspective of water pollution, wastewater and its treatment within the context of electrotechnical production. The thesis is based on the laboratory task in the practical part, which has been included in the Ecology of Production class. The laboratory task tests the selected indicators of water quality using titration and rapid tests. The thesis is based on the wastewater operation of a company producing PCB.
Determination of CO2 exhaust emissions for CNG, petrol and diesel vehicles
Chytil, Ivo ; Libich, Jiří (referee) ; Bača, Petr (advisor)
The thesis deals with the topic of Carbon dioxide emissions that are created by Petrol, Diesel and CNG vehicles. In the first part of the thesis, the results of theoretical calculations are compared with the values of the manufacturer of the specific vehicle. In the second part, a specific method has been selected for calculations with real data from transport. The savings of CO2 produced by the specific vehicle are expressed in percentage – depending on the fuel used. The operating expenses from the real data are calculated and compared with hybrid and electric vehicles. In the final part of the thesis, the ratio of fleet type vehicles to the financial/ecological aspect was proposed.
Waste heat recovery from technological processes
Bednařík, Jakub ; Bača, Petr (referee) ; Vaněk, Jiří (advisor)
Master thesis deals with the utilization of waste heat from Nova Mosilana company. Theoretical part of this work is focused on the waste heat description (heat, heat quantity, heat temperature/quality, composition of waste stream) in which a considerable energy potential is hidden. The other parts describe waste heat technology, especially heat pumps, Organic Rankine Cycle (ORC) and system absorption cooling. Some of the technologies described in the theoretical part are used in the design of the more efficient existing waste heat utilization, especifically power and cold production.
