Enhanced Automated Condition Assessment of Induction Motor Bearings: A Novel Approach Using Matrix Pencil Mean Frequency Signal Processing and Multilayer Perceptron Neural Networks

IET Electric Power Applications
Vibration signal analysis plays a vital role in the condition‐based preventive maintenance of induction motor by identifying early signs of motor issues, avoiding costly breakdowns and optimising the motor's maintenance schedule.

A fully parallel method for tridiagonal eigenvalue problem

International Journal of Mathematics and Mathematical Sciences, 1994
In this paper, a fully parallel method for finding all eigenvalues of a real matrix pencil (A,B) is given, where A and B are real symmetric tridiagonal and B is positive definite. The method is based on the homotopy continuation coupled with the strategy

Finding Zeros of Analytic Functions and Local Eigenvalue Analysis Using Contour Integral Method in Examples

Advances in Electrical and Electronic Engineering, 2017
A numerical method for computing zeros of analytic complex functions is presented. It relies on Cauchy's residue theorem and the method of Newton's identities, which translates the problem to finding zeros of a polynomial.

The Grammatical Structure of Scientific Revolutions

Theoria, EarlyView.
ABSTRACT In this article, I examine the structural parallels between Thomas Kuhn's philosophy of science and Ludwig Wittgenstein's later thought, focusing on the idea of grammatical frameworks. My central claim is that Kuhn's concept of paradigm and its later, more language‐centred forms in his philosophy can be read as a Wittgensteinian grammatical ...

Matrix Pencil for RFID Collision Recovery

IEEE Access
Collision recovery is considered one of the main potentials for improving bulk reading speed in the UHF radio identification (RFID) system. The collision occurs when two or more tags reply at the same time.

Transparent Boundary Conditions for Finite Element Method-Based Parabolic Equation [PDF]

Journal of Electromagnetic Engineering and Science
In this letter, we propose a novel transparent boundary condition (TBC) for finite element method-based parabolic equation (PE) analysis. Conventional PE analysis uses a Hamming window, etc., adding an extra region to suppress non-physical reflected ...

Musical signal spectrum analysis with the matrix pencil method [PDF]

The Journal of the Acoustical Society of America, 1994
The matrix pencil spectrum analysis method provides an interesting alternative to classical Fourier analysis. The method is based on the assumption that the signal can be represented as a sum of exponentially damped sinusoids whose parameters (frequency, damping factor, amplitude and phase) are estimated by a matrix-based algorithm.

Power and Loneliness: The Role of Cultural Values

International Journal of Psychology, Volume 61, Issue 5, October 2026.
ABSTRACT Loneliness–the subjective, unpleasant state of social disconnectedness–has long been recognised as a public health concern and is estimated to affect 16% of the global population. There is some evidence for the social benefits of power in protecting one from loneliness, but theories and evidence remain inconsistent.

Reproducibility and positioning sensitivity of CT beam width measurements using a pencil ionization chamber and radiopaque mask

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Purpose To evaluate the reproducibility and precision of CT beam width measurements using a pencil ionization chamber and radiopaque mask and to assess the robustness of the technique against clinically realistic setup errors in the superior‐inferior (SI) and anterior‐posterior (AP) directions. Methods Beam width was measured on a GE Discovery

Language Experience Shapes Creative Idea Generation

The Journal of Creative Behavior, Volume 60, Issue 3, September 2026.
ABSTRACT Bilinguals often outperform monolinguals on creative tasks, suggesting a positive link between bilingualism and creativity. However, the inconsistent definitions of both bilingualism and creativity have made it difficult to understand the precise factors driving the association.
