Minidarpa robot - navigation system design
Kuna, Zdeněk ; Žalud, Luděk (referee) ; Kopečný, Lukáš (advisor)
This bachelor’s work is devided into two parts. The first part is theoretical, because it includes the principles of satellite navigation and the metodies of giving precision to position.The second part is aplication part and it describes the navigation subsystem of hardware and software equipment. The result of this bachelor’s work was made a navigation subsystem for robot, designed communication and implemented navigation algorithm into the robot.

Nonlinearity in the course of acqusition date in optical coherence tomography
Kadla, Jan ; Kolář, Radim (referee) ; Kuna, Zdeněk (advisor)
This bachelor thesis builds on my semestral work, thus provides a description of the problem of optical coherence tomography imaging system in terms of a brief historical development, structural parts and modifications. Previous work is supplemented by a more detailed description of data acquisition and especially signal processing. I present examples of the clinical and research application of this technology, and try to objectively refer to its advantages and disadvantages. Chapter dedicated to the description of a practical measurement explains selected data collection procedure and clarifies their following processing. At the end of the work are summarized the results achieved, including the considerations of potential errors during the measurement.

QRS detection in ECG signals
Kuna, Zdeněk ; Vítek, Martin (referee) ; Kozumplík, Jiří (advisor)
This project considers methods of construction QRS detectors. It focus in detection complexes of QRS single leads and space speed, which are calculated from three orthogonal leads. In theory was refer to various methods, which lead to design detector. It were designed two algoritms (constant and adaptive detecting threshold), which were implemented into detector and the signal was preprocessed by Hilbert transformation. Toward algoritms were completed by modification, which improved detection effectivity. Function of algoritms were tested in all signals of CSE (V2,V5,aVF).

Measure of EKG signals and design of software QRS detection
Handl, Marek ; Kolář, Radim (referee) ; Kuna, Zdeněk (advisor)
This work deals with the ECG signal detector and the implementation of the QRS complex. The paper briefly describes the anatomy of the heart, the emergence and spread of potentials that are evoked activity myocard. It follows introduction to the methods reading of ECG signals and the possibility of automatic classification of rhythm. The thesis also describes some of QRS detection algorithms and database PhysioNet, which includes a library of physiological signals. Finally are given the possibility of a computer system Biopac which is used for measuring biological signals. The second part focuses on the design of an algorithm of QRS complex detection and classification of the basic rhythm in the Matlab environment. The detector is tested on both test data, and the signals measured Biopac system. The work is also very effective optimization of the detector.

Myoelectric prosthetic device of human arm
Lutz, Jan ; Kozumplík, Jiří (referee) ; Kuna, Zdeněk (advisor)
This project treats of using electromyograph as a control standard for prosthetic replacement of human arm. The work is mainly focused on surface signals. Reader is briefed by creation and transmission of the signal. The work takes account of the transmission of the signal for surface electrodes and the differences between the ideal and the real connection. Another point of the thesis is the design of basic system model for simulation of the robotic arm movement, which depends on the measured signal. In the practical part there is the realization of the artificial limb movement. It starts with the roboric arm construction and continues with the communication between computer and the robotic arm. First part of practical testing ends with creating of an user interface, which is capable of control all robotic arm movements. The interface is combined with a computer model in Matlab robotic toolbox. The model is able to move in sync with the real robot. The final part is devoted to practical measurement with Biopac instruments. The obtained signal is modified to be used as controller for the robotic arm. Author's aim is to adjust this movement to be most similar to real movement.
