The Linearly Independent Non Orthogonal yet Energy Preserving (LINOEP) vectors [PDF]

open access: yes, 2014
It is well known that, in any inner product space, a set of linearly independent (LI) vectors can be transformed to a set of orthogonal vectors, spanning the same space, by the Gram-Schmidt Orthogonalization Method (GSOM).

The Measurement and Elimination of Mode Splitting: From the Perspective of the Partly Ensemble Empirical Mode Decomposition

open access: yesComplexity, 2018
The problems of mode mixing, mode splitting, and pseudocomponents caused by intermittence or white noise signals during empirical mode decomposition (EMD) are difficult to resolve. The partly ensemble EMD (PEEMD) method is introduced first. The PEEMD method can eliminate mode mixing via the permutation entropy (PE) of the intrinsic mode functions (IMFs)

Denoising in Biomedical signals using Ensemble Empirical Mode Decomposition

open access: yesIOSR Journal of Electronics and Communication Engineering, 2014
In this paper a novel Ensemble Empirical Mode decomposition (EEMD) and adaptive filtering is proposed to filter out Gaussian noise and contact noise contained in raw biomedical signals. Real Biomedical signals from the MIT-BIH database are used to validate the performance of the proposed method.

Ensemble All Time-Scale Decomposition Method and Its Application in Bevel Gear Fault Diagnosis

open access: yesSensors
All time-scale decomposition (ATD) is a non-parametric adaptive signal decomposition method, which relies on zero-crossing points and extreme points to jointly construct the baseline, achieving the suppression of modal mixing caused by the proximity of ...

Occipital and left temporal instantaneous amplitude and frequency oscillations correlated with access and phenomenal consciousness [PDF]

open access: yes
Given the hard problem of consciousness (Chalmers, 1995) there are no brain electrophysiological correlates of the subjective experience (the felt quality of redness or the redness of red, the experience of dark and light, the quality of depth in a ...
