Adaptive Clustering and Optimization With Hardware-in-the-Loop Validation for Enhanced Overcurrent Relay Protection in Power Distribution Networks

IEEE Access
This study presents an adaptive clustering and optimization approach to enhance overcurrent relay (OCR) protection in power distribution networks. Network topologies were initially clustered into four groups based on total operating times using both K ...

Anatomists' experience and perspectives on the international transfer of human remains for the purpose of education

Anatomical Sciences Education, EarlyView.
Abstract Anecdotally, educational institutions without access to human remains may choose to import these from other countries; however, there is currently no published information illuminating the existence of this trade. This study therefore aimed to document the nature of international transfer of human remains for education, and explore anatomists'
