Transfer Learning‐Based Data‐Fusion Model Framework for State of Health Estimation of Power Battery Packs

Battery Energy, Volume 4, Issue 6, November 2025.
To handle nonlinearity and feature coupling, a data‐driven aging model is proposed, employing dual Gaussian Process Regressions and transfer learning to enhance model efficiency and accuracy. Adaptive filtering refines the model by integrating aging features and output capacity, resulting in a closed‐loop data fusion framework for SOH estimation ...

Amplifier‐Based Programmable Metasurface for Bidirectional Full Polarization Enhancement

Small Structures, Volume 6, Issue 11, November 2025.
An amplifier‐based programmable metasurface is proposed to enhance bidirectional propagation of various polarized electromagnetic waves. The metasurface incorporates patch scatterers, reconfigurable phase shifters, and negative resistors to manipulate wave direction and improve wireless communication coverage. The Class‐E reflection amplifier minimizes

Enhanced Lithium‐Ion Battery Parameter Estimation and SOC Prediction via Variable Forgetting Factor Bi‐Loop Recursive Least Squares

Energy Science &Engineering, Volume 13, Issue 10, Page 4933-4943, October 2025.
ABSTRACT The reliability of parameter accuracy in lithium‐ion battery models plays a crucial role in the efficiency of state‐of‐charge (SOC) estimation methods that employ model‐based strategies. To address the limitations of traditional recursive least squares (RLS) algorithms in tracking dynamic battery characteristics, This paper introduces a bi ...

Hybrid of Thevenin and Norton Equivalent Circuits Analogous to a Source Equivalence Theorem in Electromagnetics

Celal Bayar Üniversitesi Fen Bilimleri Dergisi, 2020
According to the conventional perception among engineers, once a circuit is reduced to its Thevenin or Norton equivalent, the voltage and current may be determined only at the load, but not in the remaining parts. The other voltages and currents that exist in the remaining parts of circuit should be determined by returning to the original circuit ...

An Improved Equivalent Circuit for Electric Field Sensors in Geophysical Exploration

Geophysical Prospecting, Volume 73, Issue 8, October 2025.
ABSTRACT In electromagnetic measurements, electric field sensors consist of two halves, with remote electrodes of negative and positive polarity coupled through wires and low pass filters to the differential inputs of an analogue‐to‐digital converter; the electrical ground of the analogue‐to‐digital converter is connected to the ground through a ...

Metallicities of Young Open Clusters I: NGC 7160 and NGC 2232

, 2010
We present a moderate-resolution spectroscopic analysis of the 10-25 Myr clusters NGC 7160 and NGC 2232, using observations obtained with the WIYN 3.5-m telescope. Both NGC 7160 and NGC 2232 are found to have super-solar metallicities, with a mean [Fe/H]
