Comparison of heart activity sensing devices
Babicová, Martina ; Smital, Lukáš (referee) ; Smíšek, Radovan (advisor)
The goal of this work is comparison of heart activity sensing devices. However, an ECG record cannot be evaluated with the presence of muscle interference. Removing this noise is one of the needs for device success. The theoretical part represents electrophysiology of the heart, electrocardiography, various interferences types, theoretical basis for recording of biosignals including used devices and methods signal quality estimation. The practical part is SNR (signal-to-noise ratio) calculation. The Wavelet filter and Wiener filter-based wavelet domain are used to separate the useful and noise component.

Comparison Of Heart Activity Sensing Devices
Babicová, Martina
The goal of this work is comparison of heart activity sensing devices. ECG record cannot be evaluated in the presence of large amounts of muscle noise. Removing this noise is one of the needs for devices success. The discrete wavelet transform is used to separate the useful and noise component. The result is an estimate of SNR for four devices: CorScience, Faros, BiosignalPlux, CardioSignal and a comparison between them. Quality measurement and evaluation indicates that Faros device is the most reliable.

Long-term sustainability of state debt financing and the impact on development activities of the Czech government
Babičová, Martina ; Maaytová, Alena (advisor) ; Klazar, Stanislav (referee)
The aim of the thesis called: Long-term sustainability of state debt financing and the impact on development activities of the Czech government, is to evaluate the long-term sustainability. To achieve this aim the analysis of the development of the Czech state debt and identification of factors working for the deepening of fiscal imbalance was conducted. The work also explores the relationship between state debt and state budget expenditures on development activities of the government. Spending on research, development and innovation were chosen to identify that relationship. On the basis of the analysis there are suggested possible changes in fiscal policy which could contribute to improving the current situation and rebalance.
