Classification with Use of Neural Networks in the Keras Environment
Pyšík, Michal ; Burgetová, Ivana (referee) ; Bartík, Vladimír (advisor)
Tato práce zkoumá problematiku klasifikace pomocí umělých neuronových sítí s využitím knihovny Keras, poskytující vysokoúrovňové rozhraní pro práci s umělými neuronovými sítěmi v programovacím jazyce Python. Cílem práce je prozkoumat rozsáhlé možnosti této knihovny v oblasti klasifikace a porovnat různé typy a topologie umělých neuronových sítí formou experimentů na vybraných datasetech, což je doplněno jednoduchou experimentální aplikací sloužící především jako rozhraní pro tyto experimenty.

Allelopathy of aquatic plants and its possible application to control cyanobacterial blooms
Kolářová, Anna ; Jandová, Kateřina (advisor) ; Kučerová, Andrea (referee)
The excessive growth of phytoplankton and the development of water bloom leading to the damage to aquatic ecosystems are becoming a more and more frequent problem. There are many methods to control the water bloom from which mainly those that use interactions of living organisms have been developing lately, with the utilisation of aquatic plant allelopathy being one of them. Allelopathy is a type of relationship between two organisms when one of them influences the other by secreting allelopathically active compounds in the environment. However, the effect of these secondary metabolites depends on many biotic and abiotic factors, which also has consequences for their potential use to control the water bloom. Although the results of many studies suggest that allelopathy can affect the community of phytoplankton, its role in aquatic ecosystems is still unclear. This thesis summarizes the knowledge about the occurrence of allelopathy among aquatic organisms, the modes of action of allelochemicals and the impacts of the key factors influencing the allelopathic effect. At the same time, it evaluates the prospects of using the allelopathy of aquatic plants to control water bloom and reviews experimental approaches to studying allelopathic interactions.

Investigation of recycling possibilities of discarded photovoltaic solar panels
Šperlich, Antonín
This work aims to find an economically effective and industrially feasible method of how to recycle discarded photovoltaic solar panels. Performed experiments determined the exact composition of photovoltaic solar panels and the advantages and disadvantages of the treatment mentioned in the literature. Results will be used for a full-scale industrial unit design for solar photovoltaic panels recycling.\n

The importance of empiricism in the work of Jan Evangelista Purkyně
Buřičová, Karolína Tamara ; Strnadová, Lucie (advisor) ; Arndt, Tomáš (referee)
The diploma thesis on the topic of The importance of empiricism in the work of Jan Evangelista Purkyně describes his approach to medicine, experiments designed by him and the study of the physiology of the human body through the senses. At the beginning of my work, I briefly describe the historical context and Purkyně's concept of subjective observation. His philosophical ideas about the soul and psychological knowledge are also described here. The main part of the work contains a detailed description of Purkyně's experiments in the field of experimental pharmacology, visual phenomena but also on hearing and dizziness. Based on these experiments, Purkyně then contributed to new discoveries key to medicine as we know it now.

Application for Outlier Detection
Siladi, František ; Bartík, Vladimír (referee) ; Burgetová, Ivana (advisor)
The goal of this work is to investigate methods for outlier detection and to create an application which is able to correctly identify these values using individual methods or combinations of outlier detection methods. Another goal of the application is to clearly display the results of outlier detection and then visualize them in 2D or 3D space. The work also includes experiments on selected data sets, which are adapted to outlier detection and on automatically generated sets. The application and experiments were created in Python and Qt for Python was used to create the graphical user interface.

Inter-subject relations between chemistry and geology in natural sciences
Kálalová, Anna ; Čtrnáctová, Hana (advisor) ; Teplý, Pavel (referee)
Thesis is fixed on inter-subjects relations between chemistry and geology in context of science education. Thesis concern subject matter defined in curricula for grammar schools, which is devoted inorganic chemistry, mineralogy and petrology. Next there is lucid compile inclusion these themes to school curricula in other grammar schools. Thesis emphasizes mainly to practical works in teaching mentioned subjects i.e. experiments. There are compile topics for chemical and physical experiments, which are useful for demonstration inter- subject relations between these subjects and geology. Worksheets with creative solutions were made for these experiments; there are component of enclosure of this thesis.

Ways for self development of teaching strategy
Pešinová, Karolína ; Jirotková, Darina (advisor) ; Hejný, Milan (referee)
Ways for self development of teaching strategy Abstract: The aim of this thesis is to analyse the diagnostic tools designed by M. Hejny and his team. These tools focus on teaching styles in education, observing the personal development of a mathematics intern teacher. The study materials i have obtained during my practice are used to describe and analyse the teacher's educational style, with the use of twenty defining parameters. My thesis is based on Gabriela Hlavata's master thesis, a teacher who describes her own shift from transmissible to constructive teaching in mathematics classes. Hlavata depicts this shift clearly, hence the reason I have decided to describe it with a set of parameters measuring the intern teacher's educational style. The subsequent aim is to trace my own evolution in teaching mathematics. Practice and materials gained in my graduation, together with the twenty educational parameters as outlined in my thesis, will serve to analyse and describe my own educational style. In choosing this topic, I am trying to answer the following question; whether the observation of a teacher's educational style will impact on the delivery and quality of mathematics lessons? Furthermore, is improvement possible, or have I reached the capacity of my own teaching ability? Additionally this thesis...

Educational use of geological park Czech Paradise in teaching upper primary school biology
Zrůstová, Klára ; Teodoridis, Vasilis (advisor) ; Skýbová, Jana (referee)
The presented diploma thesis has an educational character and tries to find a way how to teach geology more attractive at primary schools. It includes authorial proposals for field trip routes and school experiments that can be implemented in lessons or within other educational school activity during school year. The field trips are built to be carried out in the geological park of Bohemian Paradise because of its natural wealth giving many possibilities to be used in teaching geology and other related fields of natural sciences. The experiments are designed to be realized during school lessons, therefore they are meant to be as little as possible time consuming and also the necessary material is supposed to be easily available. A theoretical part of the diploma thesis contains a summary of available natural datasets about the geological park of Bohemian Paradise, a review of the educational principles for organising of the field trips, creating worksheets, experiments and games in teaching process. The principles of creating concept maps are also included. An integral part of the thesis is authorial research with students and teachers via questionnaire survey proving that experiments and field trips are an indispensable component of teaching process and appropriate motivational tools at primary...
