Terminal for testing of data communication of public transport vehicles
Fiala, Michal ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
This term paper deals with subject of wireless communication of city rail transport cars. In this paper are described individual modules for transmission and receiving of data containing communication between city rail transport cars and measures of siding switches. Then there are discussed possibilities of design of system for testing functionality of transmitting and receiving modules and the system is consequently designed. There are also described communication principles and protocol used for wireless communication and MODBUS protocol used for communication over RS-485 serial line. In the end was the system manufactured, completed and equipped with necessary software.

Microprocessor controlled inverter for motors
Fiala, Michal ; Červinka, Dalibor (referee) ; Knobloch, Jan (advisor)
This diploma thesis deals with design of universal converter used for motor control by microcontroller. The first part contains concept, functional overview of the device and its parts. The next part deals with mechanical design and construction of the converter and dimensioning of power, control and measurement circuits. The following part describes control algoritm used for three-phase motor and its testing using simulation. The final chapter of the thesis describes PCB mounting and testing of the device and control algoritm on real motor.

Automatic design of synchronous machines
Fiala, Michal ; Mach, Martin (referee) ; Cipín, Radoslav (advisor)
This bachelor thesis deals with problematic of design of synchronous machines. First part is dedicated to descript function and structure of a synchronous machine. The next part describes an algorithm of design of wound rotor and permanent magnets synchronous machines. Based on the described method, the program for automated design of these types of synchronous machines was created in the programming environment Matlab. At the end of the thesis, there are described the results that were achieved within the work.

Mineral wool and binding agent interaction and behavior study
Fiala, Michal ; Šoukal, František (referee) ; Ptáček, Petr (advisor)
Diploma's thesis describes resolution of cause technological problems in mineral wool manufacturig in company Saint-Gobain Orsil. Main attention is paid to thermal and volatile process in mineral wool from filtration chamber and common commercial sales. Samples of mineral wool were characterizated by thermal analysis (simultaneous TG-DTA), effluent gas analysis (EGA), infrared spectroscopy (FT-IR), electron microscopy (SEM) and X-ray diffraction (XRD). Thermal analysis experiments was used to check thermal volatile processes. Technological problem of burning is linked with rise of isocyanic acid.

Analog display with microcontroller
Fiala, Michal ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
The bachelor thesis deals with subject of voltage measurement. In this project are briefly described basic types of measurement instruments and their principles. In the part dedicated to digital meters are described principles and function of A/D converters. Then are described parameters of components used in design of desired measurement instrument and their connection to electric circuit. Last part is dedicated to software of the instrument, control of its parts and processing of measured data.

Capital Market Anomalies
FIALA, Michal
This work describes a total of three theories by which capital market price movements can be explained, as well as capital market anomalies. Empirical research is focused on the analysis of temporal anomalies, namely the day-of-the-week effect and the month-of-year effect. These effects were analysed on three indexes, namely the NASDAQ Composite Index, Euronext 100 Index and SSE Composite Index. These effects are tested first using the statistical testing method and then more closely using the linear regression method.

nalysis of Indebtedness of Students
FIALA, Michal
This work pursues the matter of indebtedness of young people. It focuses mainly on analysing the answers given by the young people in a survey which was conducted between students. Based on the results given by the survey we estimate indicators such as an income, expenditure and how many youngsters already have an experience with loans. The answers from the survey are also used for descriptive statistics or evaluation of hypothesis. For this the chi-square test is used. From this test we are able to say whether the men are more likely to be in debt or not or if there is some connection between the loans and the education. The aim is also to compare the supply of loans for the young people which are offered either by the banks or the non-bank institutions. The information for the comparison is based on the internet sources.

Case Study of Physiotherapy Treatment of a Patient after Hemorrhagic Stroke with Left-Sided Hemiparesis.
Fiala, Michal ; Opatrná Novotná, Irena (advisor) ; Zimermanová, Helena (referee)
Title: Case study of the physiotherapy treatment of a pacient after hemorrhagic stroke with left-sided hemiparesis. Objectives: The aim of the bachelor thesis is to summarize a theoretical information about stroke and to process the case report of the pacient after hemorrhagic stroke with left - sided hemiparesis. Summary: The bachelor thesis is about hemorrhagic stroke and contains two parts. The theoretical part deals with the informations about stroke. The second special part is about a case study of the physiotherapy care of the pacient after hemorrhagic stroke with left - sided hemiparesis, which I worked with during the clinical practise in Fakultní nemocnice Královské Vinohrady in the term from 24.1.2022 to 3.2. 2022. Keywords: Stroke, hemorrhagic stroke, left-sided hemiparesis, rehabilitation after the hemorrhagic stroke, physiotherapy procedures and methods.
