Seismic activity measurement using fiber optic sensors
Vaněk, Stanislav ; Horváth, Tomáš (referee) ; Vojtěch, Josef (advisor)
The aim of master's thesis is to get familiarized with the problems of measurement and analysis of seismic waves. Theoretical part deals with the description of seismic waves, especially their types, sources and properties. Attention was afterwards focused on the measurement systems of these waves, emphasis was placed on their principles and advantages. The practical part discusses methods of noise reduction and highlighting of significant events in measured data. At the end, individual methods are implemented into user-friendly graphical interface.

Semi-automatic computerized system for the segmentation of online handwriting
Gavenčiak, Michal ; Mekyska, Jiří (referee) ; Zvončák, Vojtěch (advisor)
The prevalence of developmental dysgraphia among school children is between 10-30%, yet in Czech Republic, there is no objective method to diagnose it or determine its severity. Past studies have shown the possibility of automatic diagnosis using digital data gathered using a digitizing tablet and a stylus. Data gathered within an ongoing study contain information on position, time stamp, tilt, pressure and azimuth of the stylus. These data are, however, unsuitable for further analysis due unspecified number of exercises contained in one SVC file. Within this thesis the data is analysed and a program, which is able to segment these data into units of exercises and display the processed data on the screen, is designed and implemented.

Trajectory Planning with Laser Proximity Scanner
Přecechtěl, Vít ; Burian, František (referee) ; Žalud, Luděk (advisor)
This thesis deals with a trajectory planning for a mobile robot using measured data obtained from proximity laser scanner, which is mounted on mobile robot. The document begins with brief explanation of the trajectory planning problem in an unknown environment. Thesis continues with description of proximity laser scanner, physical principles and its aplication in robotics. After that hardware and software resources used for implementation and testing algorithms are described. The most important hardware is proximity laser scanner SICK LMS111 and evaluation board STM32F4-Discovery with 32bit microcontroller ARM Cortex-M4F. Software SOPAS Engineering Tool provided by SICK company is used for setting LMS111 scanner. Microcontroller programming has been done in integrated development environment CooCox CoIDE. Last part of thesis describes the algorithms of data segmentation, planning the longest trajectory and planning wall following trajectory of mobile robot.

Evaluation of viability of cardiomyocytes
Kremličková, Lenka ; Čmiel, Vratislav (referee) ; Odstrčilík, Jan (advisor)
The aim of this diploma thesis is to get acquainted with the properties of image data and the principle of their capture. Literary research on methods of image segmentation in the area of cardiac tissue imaging and, last but not least, efforts to find methods for classification of dead cardiomyocytes and analysis of their viability. Dead cardiomyocytes were analyzed for their shape and similarity to the template created as a mean of dead cells. Another approach was the application of the method based on local binary characters and the computation of symptoms from a simple and associated histogram.
