Fault Detection, Classification and Localization in Power Transmission Lines Using ANN

Zbornik radova
Abstract Power transmission line is key equipment in secure and reliable power flow in each power system. To arise reliability and security of overhead power lines, different types of failures should be simulated to minimize their impact and to detect and resolve them as quickly as possible. The objective of this paper is to provide an accurate

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.
