Temperature controller of microwave reactor
Pokorný, Ondřej ; Chomát, Luděk (referee) ; Pivoňka, Petr (advisor)
Simple low-cost temperature feedback control loop was created, using personal computer as control and data acquisition element. It controlled the temperature inside mircowave pressure reactor. Medium in reactor tank (volume about 600 ml) was calorified by 1,8 kW magnetron, which power was driven by PSD controller. The PC- process interface was made by USB data acquisition modul UD128A8D. The utility program was written. It implemented PSD controller and data acquisition function. Furhtermore it implemented interface which enabled user to set the technological curve (time-temperature relation). The protocol of experiment was automatically stored to Micosoft Excel file before the program’s termination.

Detection of Anomalies in Pedestrian Walking
Pokorný, Ondřej ; Orság, Filip (referee) ; Goldmann, Tomáš (advisor)
The goal of this work was to create a system that would be able to detect anomalies in pedestrian walking. As the core of my application, I have used OpenPose, which is an application for detecting human skeletons. Then I used a bidirectional LSTM neural network to detect anomalies in video sequences. This architecture was chosen during the experiment because it outperformed other solutions. I trained my model to detect three types of anomalies. The output of my application is a video with marked sequences of anomalies. The whole system is implemented in Python.

Upgrading of Jindřichov na Moravě and Branná Railway Stations
Kubina, Jiří ; Pokorný, Ondřej (referee) ; Svoboda, Richard (advisor)
The master thesis "Upgrading of Jindřichov na Moravě and Branná Railway Stations" deals with designing new platforms that are suitable for people with reduced mobility in accordance with applicable laws and standards. Platforms with the platform edge height of 550 millimetres above the top of rail were designed. The speed limit was increased from the original 40 km/h up to 50 km/h. Moreover, the thesis design reconstruction of railway superstructure and railway substructure and deal with the drainage system.

Line in the Drawing and Painting
Pokorný, Ondřej ; Pfeiffer, Jan (advisor) ; Vačkář, Adam (referee)
The bachelor's thesis deals with the topic of line, especially in figurative art, as a concept and gradually focuses mainly on its subdivision within fine art and its specific use in the work of selected artists, especially from the 19th century to the present. Within the framework of the division of types of line, it explores these different perspectives, which it shows through representative examples. It also describes a new way of dividing the line according to the object depicted. Selected authors are briefly described, and the principles of their different and often innovative approaches to the use of line are further explored. As part of the practical part, I describe my own way of working with line using selected artworks. I also explain here the principles and connections of my work to the geometric tendency more generally. These works are here divided into thematic series, which are justified in terms of motivation, sources of inspiration, etc. The didactic part then builds on the previous chapters and presents two themes for the application of line in art education with a total of four art tasks. Some of the art tasks were developed by the pupil in the home environment. KEYWORDS Line, drawing, painting, geometrization, figurative art

Desing and implementation of the LCC converter application for emulation validating of the integrated LLC converters
Pokorný, Ondřej ; Levek, Vladimír (referee) ; Prokop, Roman (advisor)
This bachelor’s thesis deals with the design of an LLC converter, which will be used for the verification of prototypes of integrated circuit designs, as well as its applications. First, we address why we chose the LLC converter specifically for this application. We continue by analysing the specific type of converter and describe its function. The main point of this thesis is the numerical design with input parameters, which concludes with a simulation which verifies the calculated values. The product of the thesis is the design of the final wiring diagram of the LLC converter and the test board (module) and their realisation on PCB. The thesis concludes with a verification of the whole construction using a test board in a practical measurement. The work includes the author’s own design of a transformer, as well as a discussion on the problematics of the usage of magnetic circuits for LLC converters.

History of Indonesian Spice Trade
Hrnčířová, Zuzana ; Pokorný, Ondřej (advisor) ; Petrů, Tomáš (referee)
The aim of this work is to summarize all the important points in the history of Indonesian spice trade led by Europeans. In the introduction is geographical definition, as well as a general description of the various kinds of spices exported from Indonesia. Following a major part devoted to the history of the trade with this commodity, from early Portuguese business contacts to the Dutch Golden Age spice trade. Then the focuse are the Dutch, who consequently held a leadership role in trading. The conclusion of the work summarizes the reasons of the decline in demand for spices in the 19th century and thus concludes the period of prosperity and profit from the sale of this trading article.

The issue of abortions in Indonesia
Horčičková, Jana ; Pokorný, Ondřej (advisor) ; Petrů, Tomáš (referee)
Jana Horčičková, Problematika potratů v Indonésii Abstract: This thesis identifies and defines the basic framework of termination of pregnancy with a focus on attitude towards abortion in the Indonesian society. In the introduction is mentioned general background of this issue from the perspective of Indonesian multi-religious society, which has historically evolved from the animist cults through thecolonial regime toa democratic organization of the state.Further, there are other topics on the current status of abortion in Indonesia, a description of the valid legislative framework and public attitudes to issues related to induced abortion. The aim is to provide acomprehensive overview of the current aspects of pregnancy termination and indicate possible trends of development with an emphasis on the modernization of society as well as the impact of new medical technologies, including prevention possibilities.
