Partial Discharge Detection and Recognition in Random Matrix Theory Paradigm
IEEE Access, 2017 The detection and recognition of partial discharge (PD) is an important topic in insulation tests and diagnoses. Take advantage of the affluent results from random matrix theory (RMT), such as eigenvalue analysis, M-P law, the ring law, and so on, a ...

Inferential control with the aid of modified QPLS-based soft sensor for an industrial FCCU fractionator [PDF]
, 2010 A modified quadratic partial least squares (MQPLS) algorithm based on non-linear constrained programming is proposed, in which a sequential unconstrained minimisation technique is employed to calculate the outer input weights and the parameters of inner ...

Polar factorization of a matrix
, 1967 It is known that if A is a bounded linear operator with closed range on a Hilbert space then A can be factored as A=UH, with U a partial isometry and H non-negative and self adjoint.

Necessary conditions for reaction-diffusion system with delay preserving positivity
Electronic Journal of Qualitative Theory of Differential Equations, 2016 We consider the reaction--diffusion system with delay \begin{equation*} \left\{\begin{aligned} &\frac{\partial u}{\partial t}=A(t,x)\Delta u-\sum_{i=1}^{k}\gamma_{i}(t,x)\partial_{x_{i}}u +f(t,u_{t}) , &x\in \Omega; \\ &B(u)|_{\partial \Omega}=0.\\ \

A direct method to calculate characteristic forms
Partial Differential Equations in Applied Mathematics, 2022 We propose a method to obtain characteristic curves, Riemann variables, and characteristic forms for a partial differential system of hyperbolic waves and a first order quasi-linear partial differential equations. The method is based on a construction of

Regularized estimation of large-scale gene association networks using graphical Gaussian models [PDF]
, 2009 Graphical Gaussian models are popular tools for the estimation of (undirected) gene association networks from microarray data. A key issue when the number of variables greatly exceeds the number of samples is the estimation of the matrix of partial ...

Conditioning of Partial Nonuniform Fourier Matrices with Clustered Nodes
, 2021 © 2020 Society for Industrial and Applied Mathematics We prove sharp lower bounds for the smallest singular value of a partial Fourier matrix with arbitrary "off the grid" nodes (equivalently, a rectangular Vandermonde matrix with the nodes on the unit ...

Deep Learning-Based Channel Estimation Method for MIMO Systems in Spatially Correlated Channels
IEEE AccessThis paper proposes a deep learning-based channel estimation method for multiple-input multiple-output (MIMO) systems in spatially correlated channels. To reduce the pilot overhead of pilot symbol-assisted channel estimation, the proposed method utilizes
