Robust detection of systolic peaks in PPG signal
Gálík, Pavel ; Smital, Lukáš (referee) ; Němcová, Andrea (advisor)
This bachelor thesis deals with systolic peak detection and their usage within the PPG signal. PPG signal is widely used by portable devices like smartwatch which contributes to monitoring of vital functions during the day. The theoretical part describes heart morphology and ECG signal development which is related to PPG. Furthermore, the PPG signal is described together with its usage and recording methods. Other part describes chosen methods for systolic peak detection. The practical aim of this bachelor’s thesis is to record data and to create own PPG signal database. ECG signal has been recorded as a referential value. The algorithm for systolic peak detection has been developed and tested. In conclusion achieved results are discussed with findings of different authors.
Comparison of spirometric instruments' precision
Chmelíková, Lucie ; Janoušek, Oto (referee) ; Slávik, Vladimír (advisor)
This thesis deals with pulmonary testing with emphasis to spirometry. In the first part is introduced and described pulmonary system and its attributes. There is a clear and complete list of pulmonary characteristics and parameters. It contains integrated summary of principles that are used for pulmonary measurement devices. First part is followed by description of created virtual device using LabVIEW programming. Simple meter of lung volumes can easily create spirometric curve and automatically evaluate desired values of volume. Program is further enhanced with optional archiving of measured spirometric curve. The last part of this thesis uses statistic testing for deciding of validity or invalidity of hypothesis. By statistic testing of hypothesis we are gaining and expanding basic knowledge about spirometric devices.
