Emotion Recognition from Analysis of a Person’s Speech
Knutelský, Martin ; Shakil, Sadia (referee) ; Malik, Aamir Saeed (advisor)
Táto práca sa zaoberá analýzou rozpoznávania emócií z ľudskej reči. Jej cieľom je navrhnúť a implementovať systém, ktorý je schopný automaticky klasifikovať emočný stav z rečových nahrávok. Riešenie je založené na neurónovej sieti typu Audio Spectrogram Transformer (AST), odvodenej z neurónovej siete Vision Transformer, ktorej vstupom je mel spektrogram. Implementácia riešenia pozostáva z dvoch častí. Prvá časť sa zaoberá extrakciou mel spektrogramu zo vstupnej nahrávky reči, zatiaľ čo v druhej časti predtrénovaný AST model počíta odozvu, ktorej výstupom sú pravdepodobnosti pre uvažované emočné triedy. Tréning a vyhodnotenie implementácie bolo uskutočnené na troch dátových sadách: RAVDESS, Emo-DB a EMOVO. Získané výsledky vo forme neváženej presnosti sú 84.5 % pre RAVDESS, 91.6 % pre Emo-DB a 73.8 % pre EMOVO. Počas tréningu modelu bolo zaznamenávané emitované množstvo CO2 na základe spotrebovanej energie grafickým procesorom. Hlavným výstupom tejto práce je využitie neurónovej siete vychádzajúcej z architektúry typu Transformer, určenej pôvodone pre obrazové úlohy, na rozpoznávanie emócií z ľudskej reči. Ďalším výstupom je hodnota uhlíkovej stopy tréningu neurónovej siete, vyjadrená ako hmotnosť vylúčeného CO2, ktorá dosiahla hodnotu 1058.37 gramov.

ICT and climate change: Are information and communication technologies the problem or the answer?
Abrarova, Alsu ; Rujbrová, Šárka (referee) ; Šedrlová, Magdalena (advisor)
The role of Information and Communication Technology (ICT) in addressing climate change is controversial. This thesis aims to identify if ICT is the cause or solution to climate change by analyzing its negative and positive environmental impacts. To begin with, the carbon and energy footprints of the main ICT components will be presented, as well as ways of minimizing the negative impacts. Furthermore, the potential of ICT to reduce carbon emissions in other sectors will be analyzed. Literature related to the latest technologies, climate change, and reports from companies whose main goal is a sustainable future were reviewed. The findings of this study show that ICT has both negative and positive environmental impacts. However, it has a major potential to tackle climate change by reducing the carbon footprint and increasing energy efficiency in other sectors, which outweighs ICT’s negative impacts. It is done with the aid of new technologies, such as 5G, Internet of Things (IoT), and Artificial Intelligence (AI). Moreover, it is important to highlight the importance of further studies and collaboration of government, businesses, and consumers towards environmentally friendly ICT and a sustainable future with reduced climate change.

Determination of the carbon footprint of different waste treatment techniques
Suchomel, Ondřej ; Linda, Jakub (referee) ; Köbölová, Klaudia (advisor)
This bachelor’s thesis focuses on the issue of waste treatment, waste management and carbon footprint. The aim of this thesis is to understand the complexity of these industries and propose a plan for the city of Brno based on the research done. The first theoretical part explains the benefits of circular economy and waste analysis in Czech Republic. The ensuing part describes the process of carbon footprint calculation and presents its advantages and disadvantages of carbon footprint. The two following theoretical sections discuss the methods and possibilities of waste treatment by conventional and modern methods. Last part of this thesis is a computational design and offers a waste processing proposal for the city of Brno. This thesis predominantly addresses the advantages and disadvantages of composting and anaerobic digestion for biowaste processing. A practical use of these technologies has been proposed based on the calculations.

WtE plant carbon footprint
Staňková, Lucie ; Brummer, Vladimír (referee) ; Krišpín, Jan (advisor)
The value of the carbon footprint of the WtE plant is necessary for reducing emitted greenhouse gases. In this paper, research on carbon footprint assessment is conducted, while the principles for calculating the carbon footprint according to EN 15978 standard for the sustainability of construction works through the whole life cycle are applied. This methodology is enriched with the technological unit's carbon footprint, including processes The proposed computational model is applied to determine the carbon footprint of the WtE plant Evecont. The main contribution to the carbon footprint of the WtE plant is the use phase due to carbon dioxide in the flue gas. A substantial carbon footprint reduction can be achieved by incorporating technology to capture carbon dioxide from the flue gas (CCS technology). The results achieved for the WtE plant are compared against landfill and heat from the central heat supply system. This work provides a tool that can be applied to other process industry units, allowing the carbon footprint to be calculated in detail and benchmarks to be established for the comparison of new projects.

Carbon Dioxide in Science Education (Study Aids for Grammar School)
Kristlová, Lucie ; Šulcová, Renata (advisor) ; Urbanová, Klára (referee)
Charles University in Prague - Faculty of Science Department of Teaching and Didactics of Chemistry Albertov 3, 128 40 Praha 2, Czech Republic CARBON DIOXIDE IN SCIENCE EDUCATION (STUDY AIDS FOR GRAMMAR SCHOOL) Bc. Lucie Kristlová lucie.kristlova@gmail.com In this thesis the principles of Framework Educational Programme and method IBSE alias Inquiry Based Science Education were summarized. The results of international research PISA 2006 were evaluated. In 2006 the focus was on scientific literacy. In the theoretical part the study supporting documents on the theme Carbon Dioxide were worked up. The documents would serve teachers of Chemistry and Biology mainly at the grammar schools. Methodically processed materials were created such as presentation, worksheet and subject matter of chemical experiments with the inclusion of the author solutions. The worksheet was verified by pupils at grammar school.

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 carbon footprint of households in South Bohemia
VOŠTOVÁ, Marie
The thesis deals with carbon footprint of households in South Bohemia, namely greenhouse gas emissions associated with the ordinary activities of each of us. The main objective of this thesis is to calculate the carbon footprint of households in the South Bohemia Region. The partial aim is then to assess which of the monitored components has the largest share of the total carbon footprint. These components are heating, electricity, cars, public transport, flying and food. Another partial objective is to compare the results in sociodemographic groups, which are residence, gender, education, age and income per person. The theoretical part explains the concepts such as global warming, sustainable development, ecological footprint, carbon footprint, and three already realized research on carbon footprint. The practical part describes the data acquisition, GILDED project, which was the inspiration for this thesis and method for calculating the carbon footprint. The main part consists of evaluating the calculated results, not overall carbon footprint, but also comparisons within categories of residence, gender, education, age, and income per person. The thesis finishes with the summary, which summarizes the most important results.
