ECG quality evaluation
Vencel, Michal ; Vítek, Martin (referee) ; Smital, Lukáš (advisor)
This seminar work deals with the topic of evaluating the quality of ECG signals. The introductory chapters explain the basic characteristics of ECG signals - measurement, the form of the measured signal, methods of analysis. The cardiac physiology and pathology is presented. The most common types of noise that occur in ECG signals are also mentioned. Further, the reader is acquainted with the importance of the issue of evaluating the quality of ECG signals. In the practical part of the work, two own methods for ECG quality evaluation are presented. First, a brief theoretical introduction to the techniques used in the creation of methoda is given, followed by a description of the principle of algorithms. In order to compare the functionality of the proposed methods, three more methods from other authors are presented. Their principle is briefly described. In the final chapter, all methods are subjected to functionality testing. The results are examined and all methods are compared with each other.

Vliv sklízecích ústrojí sklízecí mlátičky na sklizňové ztráty
Vencel, Michal
The diploma thesis is focused on the types of combine headers, their design and their using during harvest season. There is written about automatics systems of the combine headers, their importance and principle of operation. The field measurements were verified by a new methodology for measuring pre-harvesting losses and harvest losses of the headers and mainly measurements were compared harvest losses of the headers combines with the cross belts and headers with variable position of the knives bar.
