Eigenvalue problems, spectral parameter power series, and modern applications
(John Wiley and Sons, 2015)
A Comparison of Segmentation Procedures and Analysis of the Evolution of Spectral Parameters
(Proceedings of the Sixteenth (2007) International Offshore and Polar Engineering Conference, 2014)
Risk assessment of diabetes mellitus by chaotic globals to heart rate variability via six power spectra
(2017-09-01)
Background: The priniciple objective here is to analyze cardiovascular dynamics in diabetic subjects by actions related to heart rate variability (HRV). The correlation of chaotic globals is vital to evaluate the probability ...
Nonstationary multi-output gaussian processes via harmonizable spectral mixtures
(Universidad de Chile, 2021)
In several disciplines, Gaussian Processes (GPs)\cite{williams2006gaussian} are the gold standard for modelling time series or functions in general, especially in cases where modelling uncertainty is required. The extension ...
A new monitoring and characterization system of partial discharges based on the analysis of the spectral power
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2015-06-01)
Partial Discharges (PD) are one of the possible causes for unexpected faults in power systems equipment, so that its measure is an essential tool for high-voltage electrical equipment maintenance. In order to characterize ...
Tests for Non-Cointegration based on the Frequency Domain
(Universidade Federal de Minas GeraisUFMG, 2014-10-24)
This thesis proposes to study the fractional cointegration in the frequency domain. Here is investigated the restrictions that the absence or the presence of cointegration imposes on the determinant of the spectral density ...
