Psi_B-energy operator and cross-power spectral density [PDF]
, 2014 In this paper we consider the hermitian extension of the cross-Psi_B-energy operator that we will denote by Psi_H. In addition, cross energy terms are formalized through multivariate signals representation.

REACTOR NOISE ANALYSIS FOR A GRAPHITE-MODERATED AND -REFLECTED CORE IN KUCA [PDF]
EPJ Web of Conferences, 2021 In graphite-reflected thermal reactors, even a detector placed far from fuel region may detect a certain degree of the correlation amplitude. This is because mean free path of neutrons in graphite is longer than that in water or polyethylene.

Power Spectral Density Error Analysis of Spectral Subtraction Type of Speech Enhancement Methods
EURASIP Journal on Advances in Signal Processing, 2007 A theoretical framework for analysis of speech enhancement algorithms is introduced for performance assessment of spectral subtraction type of methods. The quality of the enhanced speech is related to physical quantities of the speech and noise (such ...
