A fast robust numerical continuation solver to a two‐dimensional spectral estimation problem
IET Control Theory & Applications, 2022 This paper presents a fast algorithm to solve a spectral estimation problem for two‐dimensional random fields. The latter is formulated as a convex optimization problem with the Itakura‐Saito pseudodistance as the objective function subject to the ...

Moment-Based Spectral Analysis of Large-Scale Generalized Random Graphs
IEEE Access, 2017 This paper investigates the spectra of the adjacency matrix and Laplacian matrix for an artificial complex network model-the generalized random graph. We deduce explicit expressions for the first four asymptotic spectral moments of the adjacency matrix ...

A Comparative Study on Asperity Peak Modeling Methods
Chinese Journal of Mechanical Engineering, 2021 The peak identification scheme based method (three-point definition) and the spectral moments based method (spectral moment approach) are both widely used for asperity peak modeling in tribology.

Second-Order Moment Convergence Rates for Spectral Statistics of Random Matrices
Abstract and Applied Analysis, 2013 This paper considers the precise asymptotics of the spectral statistics of random matrices. Following the ideas of Gut and Spătaru (2000) and Liu and Lin (2006) on the precise asymptotics of i.i.d.

The Possibility of Measuring Nuclear Shapes by Using Spectral Lines of Muonic Ions
Atoms, 2018 We analytically calculated the shift of spectral lines of hydrogenlike ions for non-spherical nuclear shapes, such as the oblate or prolate ellipsoid of revolution.

Effects of sampling rate on automated fatigue recognition in surface EMG signals
Current Directions in Biomedical Engineering, 2015 This study investigated the effects different sampling rates may produce on the quality of muscle fatigue detection algorithms. sEMG signals were obtained from isometric contractions of the arm.
