Effect of CNT Content on Microstructure and Properties of CNTs/Refined-AZ61 Magnesium Matrix Composites

Nanomaterials, 2022
Carbon nanotubes (CNTs) reinforced magnesium matrix composites have great application potential in the transportation industry, but the low absolute strength is the main obstacle to its application.

Oscillatory Stability Assessment of Renewable Power Systems Based on Frequency-Domain Modal Analysis

Shanghai Jiaotong Daxue xuebao
The increasing penetration of the renewable energy has increased the risks of sub/super synchronous oscillations in power systems. Therefore, it is critical to accurately evaluate the oscillatory stability of renewable power systems ensuring the safe and

Asymptotics for Solutions of Harmonic Oscillator with Integral Perturbation

Моделирование и анализ информационных систем, 2017
We construct the asymptotics for solutions of a harmonic oscillator with integral perturbation when the independent variable tends to infinity. The specific feature of the considered integral perturbation is an oscillatory decreasing character of its ...

Signed distributions of real tensor eigenvectors of Gaussian tensor model via a four-fermi theory

Physics Letters B, 2023
Eigenvalue distributions are important dynamical quantities in matrix models, and it is a challenging problem to derive them in tensor models. In this paper, we consider real symmetric order-three tensors with Gaussian distributions as the simplest case,

The Normal Force Characteristic of a Novel Magnetorheological Elastomer Based on Butadiene Rubber Matrix Compounded with the Self-Fabricated Silly Putty

Advances in Materials Science and Engineering, 2021
In this paper, a novel magnetorheological elastomer (MRE) was prepared by dispersing carbonyl iron particles (CIPs) into a composite matrix compounded by butadiene rubber (BR) and self-fabricated Silly Putty.

GMRES for Oscillatory Matrix-Valued Differential Equations [PDF]

, 2010
We investigate the use of Krylov subspace methods to solve linear, oscillatory ODEs. When we apply a Krylov subspace method to a properly formulated equation, we retain the asymptotic accuracy of the asymptotic expansion whilst converging to the exact solution. We demonstrate the effectiveness of this method by computing error and Mathieu functions.

Oscillatory Maxwell-Cattaneo Ferroconvection in a Densely Packed Rotating Porous Medium Saturated with a Viscoelastic Magnetic Fluid

East European Journal of Physics
The combined effect of second sound and the viscoelasticity is examined using the classical stability analysis on the onset of rotating porous medium ferroconvection. Local thermal equilibrium is assumed between the solid matrix and fluid.

Tribologically induced nanolaminate in a cold-sprayed WC-reinforced Cu matrix composite: a key to high wear resistance

Materials & Design, 2019
A self-organized 2D nanolaminate with an average lamella thickness of ~22 nm was formed in the subsurface of a cold-sprayed WC-reinforced metal matrix composite (MMC) Cu-MoS2-WC during oscillatory sliding and it was responsible for the much more stable ...

Physiologically Relevant Fluid-Induced Oscillatory Shear Stress Stimulation of Mesenchymal Stem Cells Enhances the Engineered Valve Matrix Phenotype

Frontiers in Cardiovascular Medicine, 2020
Support of somatic growth is a fundamental requirement of tissue-engineered valves. However, efforts thus far have been unable to maintain this support long term.
