Realtime Detection of PMU Bad Data and Sequential Bad Data Classifications in Cyber-Physical Testbed
IEEE Access, 2023 Modern Smart Grids incorporate physical power grids and cyber systems, creating a cyber-physical system. phasor measurement units (PMUs) transmit time synchronized measurement data from physical grid to the cyber system.

Bearing Fault Diagnosis Method Based on Improved Singular Value Decomposition Package
Sensors, 2023 The singular value decomposition package (SVDP) is often used for signal decomposition and feature extraction. At present, the general SVDP has insufficient feature extraction ability due to the two-row structure of the Hankel matrix, which leads to mode

Enhanced Root-MUSIC Algorithm Based on Matrix Reconstruction for Frequency Estimation
Sensors, 2023 In recent years, frequency-modulated continuous wave (FMCW) radar has been widely used in automatic driving, settlement monitoring and other fields. The range accuracy is determined by the estimation of the signal beat frequency.

Matrix representations of Toeplitz-plus-Hankel matrix inverses
Linear Algebra and its Applications, 1989 Some matrix representations for the inverses of Toeplitz-plus-Hankel \((T+H)\) matrices are given as well as for \(T+H\)-Bézoutians introduced before by the authors. This representation is given as sum of products of triangular \(T+H\)-matrices. The conditions for these inverses are determined by some columns and rows of the inverse matrix or by ...

A New Approach to k-Jacobsthal Lucas Sequences
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2021 In this study, 〖CS〗_(k,n) of S_(k,n) Catalan transformation of 𝑘−Jacobsthal-Lucas sequences is defined. S_(k,n) Catalan transformation of 𝑘−Jacobsthal-Lucas S_(k,n) sequences is obtained.In addition the transformation of CS_(k,n) is written as the ...

Designing Wire Mazes for Replicating Natural Echoes to Study Bat Biosonar Function
Advanced Intelligent Systems, EarlyView.A validated framework combining efficient physical modeling (multiple scattering model) and deep learning is presented to guide wire‐maze design for bat biosonar studies. This approach rapidly generates large datasets to test acoustic distinguishability among wire arrangements.

Characterizations of matrix-valued asymmetric truncated Hankel operators
Banach Journal of Mathematical Analysis, 2023 In this paper we introduce the class of matrix valued asymmetric truncated Hankel operators. By using characterizations of matrix valued asymmetric truncated Toeplitz operators, we characterize matrix valued asymmetric truncated Hankel operators in the case when two involved inner matrices are J-symmetric.
