Deep Reinforcement Learning‐Based Control for Real‐Time Hybrid Simulation of Civil Structures

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Real‐time Hybrid Simulation (RTHS) is a cyber‐physical technique that studies the dynamic behavior of a system by combining physical and numerical components that are coupled through a boundary condition enforcer. In structural engineering, the numerical components are subjected to environmental loads that become dynamic displacements of the ...

Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

open access: yesSmall, EarlyView.
Vanadium coordination engineering induces symmetry breaking in bismuth selenites by transforming symmetry‐compensated VO6/VO5F units into directionally aligned VO5 polyhedra. The resulting non‐antiparallel vanadyl arrangement eliminates dipole cancellation and stabilizes a polar noncentrosymmetric framework with nonlinear optical activity.

Automated Identification of Thermal Transitions in Conjugated Material Thin Films Using In Situ Optical Spectroscopy

open access: yesSmall Methods, EarlyView.
This study demonstrates the effectiveness of in situ UV−vis coupled with automated data analysis, namely, ATLAS, for fast and reliable identification of multiple thermal transition in conjugated polymer thin films. This ATLAS method will significantly accelerate the understanding of the phase behavior of D‐A polymers with important implications for ...

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

open access: yessteel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Classification of Broadband Oscillations Using Wavelet Convolution and Multi‐Channel Attention Network

open access: yesEnergy Internet, EarlyView.
ABSTRACT Accurate identification of broadband oscillation types is a prerequisite for implementing appropriate control strategies. The strongly nonlinear, nonstationary and multi‐modal characteristics of broadband oscillation signals impose higher demands on identification methods. Practical applications face challenges such as coupling effects between

Recognition of Spatiotemporal Feature Images of Zero‐Sequence Voltage for Single‐Phase High‐Impedance Ground Faults Under Complex Conditions

open access: yesHigh Voltage, EarlyView.
ABSTRACT Diagnosing high‐impedance ground faults (HIGFs) in distribution networks is extremely challenging because high transition resistance significantly reduces electrical signal strength and unpredictable initial fault phase angles coupled with asymmetric voltage disturbances often lead to misclassification.
