High Impedance Faults (HIFs) are recurring events in electrical Distribution Systems (DSs) and occur by the contact between energized conductors high impedance surfaces. HIFs may pose hazards to living beings cause bushfires. However, HIF protection has not been completely solved due small fault current varying impedance, inhibiting traditional techniques from functioning correctly. In literature, researchers have mainly focused on detection techniques. Thus, development of Location Methods...
Quantitative assessment of the abdominal region from CT scans requires accurate delineation organs. Therefore, automatic image segmentation has been subject intensive research for past two decades. Recently, deep learning-based methods have resulted in state-of-the-art performance 3D segmentation. However, complex characterization organs with weak boundaries prevents learning Specifically, voxels on boundary are more vulnerable to misprediction due highly-varying intensities. This paper...
This study aims to ensure the observability of voltage sags in entire distribution system (DS) for any short‐circuit manifested by optimal allocation monitors focusing on power quality.

This letter exhibits the presence of High-Frequency (HF) current signatures arcing in Vegetation High Impedance Fault (VeHIF) events. Zero-crossing discontinuities are shown to have varying widths causing different levels HF noise bursts depending on how aggressively 50-Hz waveform gets distorted. The work has identified that temporal growth disturbances often occurs quicker than those linked third harmonic or entire Low-Frequency (LF) spectrum. In 59.2% a dataset 125 phase-to-earth...
Lung cancer is the leading cause of death and morbidity worldwide. Many studies have shown machine learning models to be effective in detecting lung nodules from chest X-ray images. However, these techniques yet embraced by medical community due several practical, ethical, regulatory constraints stemming "black-box" nature deep models. Additionally, most visible on X-rays are benign; therefore, narrow task computer vision-based nodule detection cannot equated automated detection. Addressing...
High-impedance faults are a challenging problem in power distribution systems.
