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.

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.

Implementation of local DNA structures analysis tool
Kaura, Patrik ; Trenz, Oldřich (referee) ; Šťastný, Jiří (advisor)
This diploma thesis is focused on the description and implementation of the API wrapper application, which works on top of computational core ibp bioinformatics. The first half of the thesis is focused on the summary of basic knowledge in the field of DNA research, as well as the specification of the problem and description of selected technologies. The other half deals with the actual implementation, distribution, and evaluation of application applicability on specific DNA sequences.

Preparation and realization of the railway viaduct in Ostrov nad Oslavou
Šťastný, Jiří ; Doubek, Rostislav (referee) ; Kantová, Radka (advisor)
This Diploma thesis deals with the preparation of the realization of the railway viaduct in Ostrov nad Oslavou. Realization of major technological stages is addressed in building technological study. Technological processes of each sub-job phases are supplemented by technical regulations, the design of the main building machines and mechanisms, inspection and test plan, schedule of occupational health and safety, time and financial plan construction, construction budget, a plan for securing material resources. I also worked out the technical report of the building sites facilities including drawings needed. I also worked out design rehabilitation of the substructure of the railway viaduct, which is consist of technical regulations for remediation work and drawings.

Network element project by means of neural network
Pokorný, Petr ; Krček, Petr (referee) ; Šťastný, Jiří (advisor)
The diploma thesis deal with a priority network switch whose model was made in programming environment Matlab - Simulink. Problem of optimal switching is solved by Hopfield’s artificial neural network. Produce of the diploma thesis is a model of packet switch and time-severity comparison of optimalization problem solved with or without artificial neural network. The thesis was developed in research project MSM 0021630529 Intelligent Systems in Automation.
