Localisation of discrete change in a transformer winding: a network-function-loci approach

, 2011
An entirely different approach for localisation of winding deformation based on terminal measurements is presented. Within the context of this study, winding deformation means, a discrete and specific change externally imposed at a particular position on

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

A novel approach for on-line deformation diagnostics of transformer windings

, 2010
This paper discusses an elegantly simple on-line approach for deformation diagnostics of transformer winding. The Current Deviation Coefficient (CDC) derived from terminal current measurements at a selected high frequency (HF) is found to be an effective

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

Advanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Experimental and numerical investigation of the winding process of superconducting coils made of multi-strand Rutherford-type Nb3Sn cable

, 2018
The High Luminosity-LHC (HL-LHC) project and the Future Circular Collider study (FCC) require higher magnetic fields than provided by the magnets presently installed in the Large Hadron Collider (LHC).

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

Advanced Engineering Materials, EarlyView.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.
