An improved YOLOv9-based method for identifying insulator temperature anomalies

Journal of Engineering and Applied Science
Abnormal heating of transmission-line insulators is often an early indicator of impending faults. Timely and accurate identification of overheated regions in infrared imagery is therefore critical for the safe operation of power grids.

Impact of High-Frequency Voltage Distortion Emitted by Large Photovoltaic Power Plant on Medium Voltage Cable Systems [PDF]

, 2021
Switching processes of voltage source converters can emit significant high-frequency distortions of frequencies between 5 to 20 kHz. Furthermore, the distortions can partly propagate from the place of their origin into a medium voltage system via ...

Development and Implementation of a Disease‐Targeted Storybook as a Clinical Tool for Children With Acute Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Although significant progress has been made in childhood leukemia survival, healthcare providers, and caregivers often face challenges in explaining this disease to patients. Disease‐targeted storybooks have been proposed as a tool to facilitate the understanding of diagnoses and treatment.
