Statistical moments of power spectrum: a fast tool for the classification of seismic events recorded on volcanoes [PDF]

open access: yesAdvances in Geosciences, 2020
Spectral analysis has been applied to almost thousand seismic events recorded at Vesuvius volcano (Naples, southern Italy) in 2018 with the aim to test a new tool for a fast event classification. We computed two spectral parameters, central frequency and

Distributed control of the Laplacian spectral moments of a network [PDF]

open access: yesProceedings of the 2010 American Control Conference, 2010
It is well-known that the eigenvalue spectrum of the Laplacian matrix of a network contains valuable information about the network structure and the behavior of many dynamical processes run on it. In this paper, we propose a fully decentralized algorithm that iteratively modifies the structure of a network of agents in order to control the moments of ...

Reconciling the FOPT and CIPT Predictions for τ Hadronic Spectral Function Moments [PDF]

open access: yesEPJ Web of Conferences, 2022
Recently it has been clarified by Hoang and Regner that the longstanding discrepancy between the CIPT and FOPT expansion approaches in αs determinations from the τ hadronic spectral function moments has been caused by an inconsistency of CIPT with the ...

Classifying Oromo fricatives with machine learning

open access: yesEstudios de Fonética Experimental
Using machine learning, this study investigates how segment duration, spectral moments, and DCT coefficients help differentiating singleton from geminate in Oromo fricatives.

Towards a Spectral Method of Moments using Computer Aided Design [PDF]

open access: yesAdvances in Radio Science, 2019
We present first numerical examples of how the framework of isogeometric boundary element methods, in the context of electromagnetism also known as method of moments, can be used to achieve higher accuracies by elevation of the degree of basis functions.

Faster spectral density calculation using energy moments

open access: yes, 2022
Accurate predictions of inclusive scattering cross sections in the linear response regime require efficient and controllable methods to calculate the spectral density in a strongly-correlated many-body system.

Selected Acoustic Features of the Welsh Lateral Fricative /ɫ/

open access: yesResearch in Language
The Welsh language exhibits a number of features uncommon from a cross-linguistic point of view, one of which is a relatively large number of fricative phonemes.

Dialect Classification From a Single Sonorant Sound Using Deep Neural Networks

open access: yesFrontiers in Communication, 2019
During spoken communication, the fine acoustic properties of human speech can reveal vital sociolinguistic and linguistic information about speakers and thus, these properties can function as reliable identification markers of speakers' identity. One key
