Damage Identification of Structures Using Second-Order Approximation of Neumann Series Expansion [PDF]
Journal of Rehabilitation in Civil Engineering, 2020 In this paper, a new method proposed for structural damage detection from limited number of sensors using extreme learning machine (ELM). One of the main challenges in structural damage identification problems is the limitation in the number of used ...

Effect of Important Physical and Geometrical Parameters on the Dynamic Response of Thick Composite Plates with Smart Attached Mass [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2019 In this research, the effect of different structural parameters on the dynamic behaviour of a thick plate with a smart attached mass, which is a mass embedded with the Shape Memory Alloy (SMA) fibers were investigated.

Sphaleron without shape mode and its oscillon
, 2023 We find that an oscillon can possess a characteristic double oscillation structure even though it results in a decay of a sphaleron which does not have any positive energy discrete vibrational mode (shape mode).

The Mechanism of Ultra-Low Frequency Oscillations With the Same Mode Shapes
IEEE Access, 2020 The ultra-low frequency oscillation (ULFO) problem reappears in China recently. Different from the classical low frequency oscillation (LFO), the generators in ULFO have the same mode shapes, namely oscillating in the same pace.

The shape of the fundamental sloshing mode in axisymmetric containers [PDF]
Journal of Engineering Mathematics, 2015 In the paper we numerically study positions of high spots (extrema) of the fundamental sloshing mode of liquid in an axisymmetric tank. Our approach is based on a linear model reducing the problem to appropriate Steklov eigenvalue problem. We propose a numerical scheme for calculating sloshing modes and a novel method of making images of oscillating ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...

Shaping Effects on Non-Ideal Ballooning Mode [PDF]
Plasma and Fusion Research, 2018 The dependence of shaping effects on the growth rate of collisionless and resistive ballooning mode (CBM/RBM) is numerically investigated. That of the drift ballooning modes (DCBM/DRBM) is also investigated by taking kinetic effects into account. Resistivity scans of linear growth rates of CBM/RBM and DCBM/DRBM in a circular geometry show that both ...
