Impact de la transformée de Keystone sur la détection de cibles radar

Ait Taleb, Abigael Taylor, Valentine Wasik, Yassin El Hillali

La transformée de Keystone (KT) est une méthode utilisée pour corriger la migration distance des cibles en mouvement sans connaissance a priori de leur vitesse. Cette méthode repose sur une transformation temporelle via l'interpolation de la compression d'impulsions dans le domaine…

The art and science of translucent color organic solar cells

Baozhong Deng, Yi Li, Zhouyi Lu, Kaiwen Zheng, Tao Xu, Shenghao Wang, Xiaoshu Luo, Bruno Grandidier, Jianhua Zhang, Furong Zhu

The artistic and scientific perspectives of the translucent color organic solar cells (OSCs), made with the emerging narrowband nonfullerene acceptors are explored. The translucent color OSCs, comprising a Fabry–Pérot microcavity optical coupling layer, have a power conversion efficiency of &gt…

Deep Reinforcement Learning for Joint Time and Power Management in SWIPT-EH CIoT

Nadia Abdolkhani, Nada Abdel Khalek, Walaa Hamouda, Iyad Dayoub

This letter presents a novel deep reinforcement learning (DRL) approach for joint time allocation and power control in a cognitive Internet of Things (CIoT) system with simultaneous wireless information and power transfer (SWIPT). The CIoT transmitter autonomously manages energy harvesting (EH) and…
