1. 1. Multitaper analysis of HRV power and its stress-related correlation to respiration frequency

   University essay from Lunds universitet/Matematisk statistik

   Author : Zite He; [2018]
   Keywords : Multitaper multiple windows ; Heart rate variability HRV ; Spectrum anal- ysis; Integrated pulse frequency modulation IPFM ; High frequency band HF ; Thomson multitaper TH MW ; Peak-matched multitaper PM MW ; Correlation.; Mathematics and Statistics;

   Abstract : In this Master thesis, different multitaper methods are implemented to estimate the spectra of respiratory signals and HRV data, and further to estimate the correlation between the respiratory center frequency and the narrow-banded high frequency band of HRV power. The methods are applied first on ARMA-process data, then on the integrated pulse frequency modulation (IPFM) data simulations, where the evaluation is performed by calculating the bias and standard deviation of the narrow-banded HRV power and its correlation with respiratory frequency.

3. 2. Time Frequency Analysis of EEG Measured When Performing the Flanker Task

   University essay from Lunds universitet/Matematisk statistik

   Author : Johan Brynolfsson; [2012]
   Keywords : Time Frequency analysis; Locally Stationary processes; Multitaper; EEG; Mathematics and Statistics;

   Abstract : This thesis handles time frequency analysis of EEG signals measured on participants performing the so-called flanker task. The analysis is done mainly using multitapering techniques on the quadratic class. Using multiple orthonormal windows when estimating the spectra of a process, one lowers the variance of estimate.
