Swimming analysis using a SwIMU measuring device
Láznička, Jakub ; Šťastný, Jan (referee) ; Bátorová, Michaela (advisor)
This bachelor thesis deals with the description of the inertial sensor for measuring swimmers.The work contains a description of the possibility of performing swimming performance analyzes. In the practical part, a pilot measurement was performed and a detailed manual was created containing a description of accessories, the measurement process and the methodology of subsequent evaluation. An external database in MS Excel was created to compare the evaluated measurements, used to sort data with the possibility of statistical processing.

Comparison of sensor and sensorless control of 3-phase BLDC motor
Drápal, Michal ; Šťastný, Jiří (referee) ; Roupec, Jan (advisor)
The diploma thesis is focused on comparison of sensored and sensorless control of 3phase BLDC motor. This diploma thesis was compiled with engineers from Honeywell, spol. s r. o. and NXP Semiconductors comapny. Theoretical part of the diploma thesis is describing princip of function BLDC motor and different methods of control. The testing of NXP sensored and sensorless application is done in the practical part. Regarding to the fact, that applications were provided by NXP, furthemore the diploma thesis additionally contains a state machine using sensorless application from NXP. Finally, the author is evaluating a cooperation with NXP company and he thinks about next possible cooperation.

Analysis of local DNA structures
Kratochvíl, Jaromír ; Trenz, Oldřich (referee) ; Šťastný, Jiří (advisor)
This diploma thesis is focused on the description and implementation of the user interface for the analysis of local DNA structures as a web application in the Vue.js framework. The local structure can be described as an alternative DNA structure which arises in a specific DNA sequence that occurs in important regions of the genome. The first part of the thesis is theoretical and examines the field of DNA research and a description of selected technologies. The second part deals with the implementation and testing of the user interface on specific DNA sequences.

Evaluation of targets in shooting range based on image data
Sujová, Sára ; Šťastný, Jiří (referee) ; Škrabánek, Pavel (advisor)
The thesis describes the design and implementation of a computer vision system for evaluating targets on the shooting range using image data. The program respects the restrictions based on safety measures established by the the shooting range manager and uses an uniform system of lighting and camera placement. The work consists of several parts. The first part is the creation of the dataset and its annotation. The second part is the creation of the program. The program includes a photo of the target, which is suitably edited and divided into sub-areas in the pre-processing phase. These sub-regions are then iteratively processed by the U-NET network, which produces segmentation maps that are subsequently combined into the resulting map. The positions of the detected shots are obtained from this map. In the last part of the program, a point evaluation of the shooting session is obtained.

The effect of operating position of the light source on the photometric parameters
Šťastný, Jakub ; Štěpánek, Jaroslav (referee) ; Škoda, Jan (advisor)
The theses discusses how operating position and ambient temperature affect electric light sources. For the purposes of this theses, the analysis of light radiation, the description and the principle of taking measurements of light quantities are included. The work also contains the principle of function, construction and parameters of light sources. For each light source a hypothesized impact of the operating position of the light source and the impact of ambient temperature variation on radiated luminous flux are stated. For selected light sources a measurement of the impact of the operating position on the sources’ photometric parameters was taken. The output measurement data are being compared to the theoretical hypotheses. The conclusion of the thesis describes suggested recommendations for the operation of light sources based on both theoretical and practical parts of the thesis.

Image processing within determination of topographic surface parameters
Boháč, Martin ; Ohlídal, Miloslav (referee) ; Šťastný, Jiří (advisor)
This work deal with determination topohraphic parameters of a randomly rough surface by the help of method of shearing interferometry. It is a optical method for determination surface roughness. The basic idea is based of on deformation interference strips which are made by interference of the same mutually translated monochrome luminous wavefronts. The wavefront is created after transit or reflection monochrome lights from the surface of a studied sample. The wavefronts creates picture with deformed interference strips , which carries information about character of the surface. This information can be profited by algorithms of image processing from the picture . The thesis was developed in research project MSM 0021630529 Intelligent Systems in Automation.

Finding guanine quadruplexes in DNA using decision trees
Kotrys, Kryštof ; Šťastný, Jiří (referee) ; Kaura, Patrik (advisor)
This bachelor’s thesis is focused on creating a functional decision tree model for detection of guanine quadruplexes in the DNA. The first part of the thesis summarizes theoretical knowledge in the fields of local DNA structures, computational prediction methods of guanine quadruplexes and decision trees. The second part describes the creation of a decision tree model, followed by a statistical comparison of the results with the G4Hunter algorithm.
