Research Progress in Treeing Phenomena of Polypropylene Insulation Materials

High Voltage, EarlyView.
ABSTRACT Polypropylene (PP) is increasingly utilised in high‐voltage systems due to its superior electrical and thermal properties. However, electrical treeing poses a significant threat to its long‐term reliability, potentially leading to insulation failure.

Fractal Dimension and Vector Quantization

, 2004
We show that the performance of a vector quantizer for a self-similar data set is related to the intrinsic ("fractal") dimension of the data set.

Endurance of Epoxy Resin Cast Insulation With Interfacial Micro‐Crack Defect Under 50 Hz Sine and Kilohertz Square Voltages

High Voltage, EarlyView.
ABSTRACT Crack‐type defects are commonly found in epoxy composite cast insulation due to residual, thermal and external stresses. When combined with inverter‐type voltage stress, as in epoxy cast high‐frequency transformers (HFTs), the likelihood of insulation failure increases significantly. In this study, a method setting microcracks perpendicular to

Bridging the small‐angle X‐ray scattering–X‐ray diffraction gap in disordered layered materials: the CLADIFFMOD unified framework

Journal of Applied Crystallography, EarlyView.
A unified multi‐scale framework is proposed for the consistent analysis of small‐angle X‐ray scattering (SAXS) and X‐ray diffraction (XRD) in disordered clay minerals, combining morphology, stacking and turbostratic contributions within a single formalism.

Rapid loss, and slow recovery, of coral reef structural complexity resulting from a prolonged marine heatwave

Journal of Animal Ecology, EarlyView.
Using Structure‐from‐Motion photogrammetry in a longitudinal study, we show that although coral reef habitat complexity had declined significantly by the end of the most prolonged tropical marine heatwave on record, no further losses were detected and 3 years later the reef had begun to recover this critical ecosystem function.
