Precision of yule-walker methods for the arma spectral model
(2004-12-01)
In this work a new method is proposed of separated estimation for the ARMA spectral model based on the modified Yule-Walker equations and on the least squares method. The proposal of the new method consists of performing ...
Spectral phase estimation based on deep neural networks for single channel speech enhancement
Majority of speech processing algorithms operate only with the spectral magnitude, leaving spectral phase unstructured and unexplored. With recent advancement in deep neural networks (DNNs), the phase processing became ...
Classification of mental tasks using different spectral estimation methods
(IntechOpen, 2009)
In this chapter, parametric (Burg) and non parametric (standard and Welch) spectral methods were utilized in order to estimate the spectral content of EEG signals for different mental tasks. Two parameters were utilized ...
Uniform Spectral Estimates for Families of Schrödinger Operators with Magnetic Field of Constant Intensity and Applications
(Universidad de La Frontera. Departamento de Matemática y EstadísticaUniversidade Federal de Pernambuco. Departamento de Matemática, 2010)
Spectral properties of a magnetic quantum Hamiltonian on a strip
(IOS PRESS, 2008)
We consider a 2D Schrodinger operator H(0) with constant magnetic field, on a strip of finite width. The spectrum of H(0) is absolutely continuous, and contains a discrete set of thresholds. We perturb H(0) by an electric ...
Alteration of soil properties through a weathering sequence as evaluated by spectral reflectance
(1999-03-01)
In the study of physical, chemical, and mineralogical data related to the weathering of soils and the quantification of their properties, remote sensing constitutes an important technique that, in addition to conventional ...
