Study of the ecology of electric vehicle
Varhaník, Jiří ; Jandová, Kristýna (referee) ; Jaššo, Kamil (advisor)
The first chapter of this bachelor's thesis describes the history of electric cars, their origin, success and decline at the time. The following chapter deals with the clarification of the carbon footprint with regard to the connection to other chapters in the field of ecology of passenger cars. The main goal of this thesis was to study the issues related to the ecology of passenger cars with a focus on electric vehicles in the Czech Republic. The~ecology of vehicles covers all periods of the car's life-cycle, starting with the production, following with utilization, final disposal and recycling of the vehicle. Another goal was to select and describe a suitable methodology for calculating the environmental impact of these vehicles. In the practical part, the relations and calculation methodologies were determined, data sources for individual parameters of these relations were obtained and the calculations were performed. The last part was about processing the obtained data into equations, tables and graphs.
The influence of environmental conditions of the recycling of solar modules
Langer, Filip ; Vaněk, Jiří (referee) ; Jandová, Kristýna (advisor)
This thesis is focused on experiments, goal of which is to separate protective glass apart from thin layer solar panel. This could lead to less expensive and more efficient recycling. We try to achieve the separation of the glass by thawing ethylene vinyl acetate layer, which serves as insulant and bonding material. Experiments are concluded in high temperature dryer and high temperature vacuum oven on samples of thin layer solar panel, which is for the purposes of experiments cut into same pieces by water jet cutting machine. The initiatory experiments in dryer and oven are to determine value of ethylene vinyl acetate thaw point in tested samples of panel. The thaw point is determined to be 340 °C. When exposed to this temperature, the ethylene vinyl acetate thaws enough for glass to be able to be extracted with minimal physical strength. The process is accompanied by fire destruction of tedlar layer and creation of exhaust gases. Following experiments in vacuum and nitrogen environment are to test their influence on thawing process. Exposing sample to temperature of 340 °C in vacuum led to no new results. Exposing sample to temperature of 340 °C in nitrogen environment prevented fire and achieved same level of thawing of ethylene vinyl acetate while creating less exhaust gases. Even though the fire was prevented, tedlar layer was still destroyed by the high temperature. Furthermore, particles of evaporated ethylene vinyl acetate condensed on surface of module in form of dust. Following experiments studied absorption of panel and influence of accessible solvents on thawing process. It was determined that panel is able to absorb approximately 2 % of acetone, 0,4 % of isopropyl alcohol and 0,11 % of distilled water in its own weight. Experiments with modules soaked in these solvents proved no new results in thawing process. By observing samples of ethylene vinyl acetate taken from module, thawed out of module after experiment in vacuum oven and dust condensed on surface of module after experiment in nitrogen environment, it was proven that the condensed dust is indeed ethylene vinyl acetate.
Preparation of diagnostic laboratory for accreditation
Chroustovská, Kateřina ; Polsterová, Helena (referee) ; Jandová, Kristýna (advisor)
This diploma thesis deals with the topic of accreditation of a diagnostic laboratory. It analyses theoretical knowledge in the field of accreditation, accreditation agency and its history. It contains a list and sample of documents required for accreditation and a description of the process. Part of the work is also a description of the requirements arising from the standard ČSN EN ISO / IEC 17025. The work briefly introduces the company whose laboratory is to be accredited. The following are the technologies the company uses and wants to accredit. The main part of this diploma thesis is the Quality manual, which was created with all needed attachments. This Quality manual is the most significant document, which is necessary for the process of accreditation.
Characterization of the perovskit photovoltaic cells
Kaliyev, Alexey ; Jandová, Kristýna (referee) ; Novák, Vítězslav (advisor)
The work is focused on problems of perovskite photovoltaic cells. The theoretical part describes the properties of perovskite structure, its composition and use in solar cells. There is also a brief information on silicon-based solar cells, which is followed by a comparison of the two systems. The measurement methods, which this stated and described here are used to understand problematics photovoltaic, determination of efficiency, stability and durability of the solar cell. In the practical part will focus on the application of these methods, discussion and evaluation of results.
Design of key performance metrics
Kmeť, Lenka ; Jandová, Kristýna (referee) ; Bača, Petr (advisor)
This document deals with process approach and it´s use in measuring companies performance. It presents an overview of individual approaches, from traditional containing only financial indicators to modern ones using non-financial indicators and incorporating into the measurement the areas related to customers employees and more. The work also mentions the Quality Management System contained in ISO 9001: 2015 and it´s approach to performance measurement. The chapter about metrics covers performance measures, in particular key performance indicators, their purpose, properties and distribution. Here are also presented the procedures for their determination and the pitfalls to be taken into consideration in their selection and use. Next chapters are devoted to the compilation of a metric system of specific companies.
Long-term influence of low-flammable electrolytes on negative electrodes
Valoušek, Michal ; Jandová, Kristýna (referee) ; Máca, Josef (advisor)
The thesis deals with the influence of low-flammable electrolytes on negative electrodes. The thesis describes materials used in lithium-ion batteries and functions of individual components. There is also a description of conductometry and electron microscopy, which is used in the practical part, ie during measurement. All findings are summarized at the end of the thesis.
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.
Energy yields per one hectare of land in the South Moravian Region
Plášek, Tomáš ; Bayer, Robert (referee) ; Jandová, Kristýna (advisor)
This bachelor thesis compares methods of producing elektricity in biogas plant, in thermal power plants by burning biomass, in solar power plants and compares it with production of energy of fuel cells and the energy from biofuels, like biodiesel and bioethanol. It compares the energy yields of different energy production methods and evaluates their advantages and disadvantages. It compares the energy content of these fuels by model vehicle range.
