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...

A Theoretical Analysis of the Frequency Response in p-i-n Photodiodes that Use InGaAs/InP Materials

Nesrine Bakalem, Abdelkader Aissat, Samuel Dupont, Faouzi Saidi, Mohamed Houcine Dhaou, Jean Pierre Vilcot

This investigation is centered on the analysis of frequency response characteristics of a p-i-n photodiode using InxGa$_{1-x}$As/InP. The InGaAs/InP can be developed under three conditions: compression, tensile strain, and lattice matching. Initially, we performed calculations on strain, bandgap...

Hopping motion of a particle along a substrate driven by a surface acoustic wave

Marina Terzi, Vladislav Aleshin, Jules Ghesquiere

Manipulation of small objects (particles) lying on vibrating or acoustically excited substrates is of interest for a number of applications such as micro-positioning or acoustic cleaning of surfaces. The objective is to provide a stable directed motion of a particle along a surface supporting a...

Closed-form solutions for wave propagation in hexagonal diatomic non-local lattices

F. Ongaro, P.H. Beoletto, F. Bosia, M. Miniaci, N.M. Pugno

Periodic mass–spring lattices are commonly used to investigate the propagation of waves in elastic systems, including wave localisation and topological protection in phononic crystals and metamaterials. Recent studies have shown that introducing non-neighbouring (i.e., beyond nearest neighbour)...

Boron-doped carbon nanowalls as effective electrodes for non-enzymatic electrochemical glucose detection: A novel bimodal EC-SALDI-MS approach

Ioana Silvia Hosu, M. Sobaszek, M. Ficek, R. Bogdanowicz, Yannick Coffinier

For the first time, boron-doped carbon nanowalls (B-CNWs) have been used as effective working electrodes for non-enzymatic electrochemical glucose detection. To achieve optimal response time and sensitivity, we activated B-CNWs by polarising them at 1.1 V in NaOH for 60 min. We established a robust...
