A New Data Processing Approach for the SHPB Test Based on PSO-TWER

open access: yesApplied Sciences
This study addresses the challenge of accurately determining the arrival time of stress wave signals in SHPB test data processing. To eliminate human error, we introduce the time-window energy ratio method and evaluate six filters for noise reduction ...

Hyperbolic Tangent - Based Adaptive Inertia Weight Particle Swarm Optimization

open access: yesJurnal Nasional Teknik Elektro, 2023
This paper presents a study on using adaptive inertia weight (AIW) in particle swarm optimization (PSO) for solving optimization problems. An AIW function based on the hyperbolic tangent function was proposed, with the function parameters adaptively ...

Drude Weight, Meissner Weight, Rotational Inertia of Bosonic Superfluids: How Are They Distinguished? [PDF]

open access: yesJournal of the Physical Society of Japan, 2014
The Drude weight, the quantity which distinguishes metals from insulators, is proportional to the second derivative of the ground state energy with respect to a flux at zero flux. The same expression also appears in the definition of the Meissner weight, the quantity which indicates superconductivity, as well as in the definition of non-classical ...

Sensor Deployment Method Based on Faiw-DPSO in DASNs

open access: yesIEEE Access, 2020
Distributed Active Sensing Networks (DASNs) is a new sensing paradigm, where active and passive sensors are distributed in a field, and collaboratively detect the objects. The detectability is the most important property of DASNs. “Exposure”

The weighted Inertia-Energy-Dissipation principle

open access: yesMathematical Models and Methods in Applied Sciences
The Weighted Inertia-Energy-Dissipation (WIDE) principle is a global variational approach to nonlinear evolution equations of parabolic and hyperbolic type. The minimization of the parameter-dependent WIDE functional on trajectories delivers an elliptic-in-time regularization.

Prediction model of insulator contamination degree based on adaptive mutation particle swarm optimisation and general regression neural network

open access: yesThe Journal of Engineering, 2019
The contaminants accumulated on the surface of transmission line insulator mainly come from the suspended particles in the air. Therefore, it is necessary to consider meteorological factors and environmental factors in the prediction of insulator ...

Effect of Inertia Weight w on PSO-SA Algorithm

open access: yesInternational Journal of Online and Biomedical Engineering (iJOE), 2013
Since particle swarm algorithm was proposed, because of its easy to understand and implement, the algorithm has been rapid development. However, the algorithm is easy to convergence, and the simulated annealing algorithm has strong local search ability, which can make the search process to avoid falling into local optimal solution.

Inertias of Laplacian matrices of weighted signed graphs [PDF]

open access: yesSpecial Matrices, 2019
Abstract We study the sets of inertias achieved by Laplacian matrices of weighted signed graphs. First we characterize signed graphs with a unique Laplacian inertia. Then we show that there is a sufficiently small perturbation of the nonzero weights on the edges of any connected weighted signed graph so that all eigenvalues of its ...
