Islanding Detection in Power Distribution Systems Using a Hybrid Machine Learning Approach

Vector: The Journal of Engineering, Volume 2027, Issue 1, January/December 2027.
This paper proposes a hybrid islanding detection approach that combines passive monitoring of multiple electrical parameters—such as negative sequence voltage, generator field voltage, and the rate of change of positive sequence impedance—with intelligent machine learning techniques.

Determination of the one‐electron reduced Wigner function for a molecular crystal

Acta Crystallographica Section A, Volume 82, Issue 6, Page 419-427, November 2026.
The first reconstruction of an experimental one‐particle reduced Wigner function for electrons in molecular crystals is reported. It relies on an ensemble N‐representable model jointly refined from the X‐ray diffraction and Compton scattering data.The Wigner function provides a complete phase‐space representation of a quantum state.

Physics‐Informed Multimodal Learning for Transformer‐Level Assessment of Nanocrystalline and Commercial Cores

Applied Research, Volume 5, Issue 5, October 2026.
MEPI combines magnetic flux‐density waveforms with nine operating and magnetic features through multimodal learning and Steinmetz‐informed residual refinement. It jointly predicts transformer efficiency, residual loss, and an Arrhenius‐informed relative thermal‐stress proxy.

RANCANG BANGUN FILTER PASIF UNTUK MEREDUKSI TOTAL HARMONIC DISTORTION (THD) AKIBAT PEMAKAIAN LAMPU HEMAT ENERGI (LHE) DAN LIGHT EMITTING DIODE (LED)

Lektrokom : Jurnal Ilmiah Teknik Elektro, 2021
This paper discusses the design of a passive filter system for energy saving in Energy Saving Lamps (LHE) and Light Emitting Diode (LED), but for LHE and LED lamps for current Total Harmonic Distortion (THDi) that do not meet the standard. To reduce the current THD, it can be done by installing a single tune passive filter.””In this paper, we discuss ...

Design of a Multi‐Complex Disturbance Generator Using Virtual Instrumentation for Power Quality Monitoring Research

Energy Science &Engineering, Volume 14, Issue 10, Page 4700-4721, October 2026.
A real‐time power quality disturbance generator is developed using virtual instrumentation based on LabVIEW and NI MyDAQ. The system generates IEEE‐standard PQ events with controllable noise and harmonics. Measurement uncertainty analysis confirms its reliability for realistic testing of Power Quality Disturbance detection and classification algorithms.
