Physically constrained XGBoost model for pseudo-spectral acceleration prediction

This study develops a physics-constrained ground motion model (GMM) for predicting pseudo-spectral acceleration (PSA) across 17 structural periods (0.02–4 s). Leveraging 900 seismic events from Japan’s KiK-net network, the research explicitly incorporating sensor depth and direct...

Robust Half‐Metallicity and High Curie Temperature in Inverse‐Heusler Ti 2 Co 1− x Ni x In Alloys: A First‐Principles Study

A first‐principles investigation of inverse‐Heusler Ti 2 Co 1− x Ni x In alloys ( x = 0, 0.25, 0.50, 0.75, and 1) is performed to examine the robustness of half‐metallicity under Co → Ni substitution. Spin‐polarized calculations show that the ferromagnetic XA‐type configuration i...

Linking water quality index structure to seasonal contaminant dynamics and predictive stability in a semi-arid aquifer in the F'kirina Plain of North-eastern Algeria

Groundwater quality in semi-arid aquifers is strongly controlled by inter-seasonal/interannual hydroclimatic dynamics, which regulate hydrochemical evolution and contaminant mobilization. However, the extent to which the mathematical architecture of water quality indices (WQIs) i...

Vibration Analysis of 2D Porous Functionally Graded Beams With Inclined Cracks Under Thermo‐Hygro‐Mechanical Coupling

ABSTRACT This work provides an in‐depth investigation into wave propagation in functionally graded material (FGM) beams subjected to coupled thermo‐hygro‐mechanical loading. The proposed model explicitly accounts for the presence of cracks, material porosity, axial pre‐stress, an...

Enhanced Control of 1.5 MW DFIG Generators in MRWT Systems Using GA‐Based PI‐ST‐SMC: Comparative Assessment With ST‐SMC

ABSTRACT This paper proposes a novel genetic algorithm‐based proportional–integral super‐twisting sliding mode control (GA‐PI‐ST‐SMC) strategy for the rotor‐side converter of a 1.5 MW doubly‐fed induction generator (DFIG) operating in marine renewable wind turbine (MRWT) systems....

Optimal Frequency Control in Isolated Microgrids Integrating Renewable Energy and PHEVs Using a Modified Ziegler–Nichols-Based Multistage PID Controller

Maintaining frequency stability in islanded microgrids (MGs) has become increasingly challenging due to the growing penetration of renewable energy sources, particularly photovoltaic systems, wind turbine generators (WTGs), and plug-in hybrid electric vehicles (PHEVs). The interm...
