A Detection Method for Conveyor Belt Damage with Small Size and Low Contrast by HAN Yajie, HAO Xiaoli, NIU Baoning, XUE Jindong

“…[Purposes] An improved YOLOv4 detection model is proposed to solve the problems of missing detection and false detection when the existing models detect objects with small size and low contrast with the background. [Methods] In order to solve the problem of small size, first, the DDS unit is designed to replace the Res unit in the backbone network. …”

Simulated uterine contractions: Graph theory and connectivity-based analysis of EHG signals by Kamil Bader Eldine, Noujoud Nader, Mohamad Khalil, Catherine Marque

“…Preterm labor represents the prominent cause of mortality and morbidity, highlighting the important need for improved preterm contraction prediction and management. One promising approach to resolving this challenge is to analyze the electrohysterographic (EHG) signal, which records the electrical activity regulating uterine contractions. …”
