Enhancing active reconfigurable intelligent surface

open access: yesIntelligent and Converged Networks, 2022
A Reconfigurable Intelligent Surface (RIS) panel comprises many independent Reflective Elements (REs). One possible way to implement an RIS is to use a binary passive load impedance connected to an antenna element to achieve the modulation of reflected ...

High level Petri nets‐based proposal of an integrated intrusion detection and prevention mechanism in network controlled systems

open access: yesIET Communications, 2023
The authors’ work deals with modelling with coloured Petri nets (CPN) of network controlled systems (NCS) and exposes a proposal of a sensor fault detection and prevention mechanism. In NCS, the network must be viewed as part of the system and not just a

A novel scheme based on information theory and transfer learning for multi classes motor imagery decoding

open access: yesIET Signal Processing, 2023
The most important challenges of classifying Motor Imagery tasks based on the EEG signal are low signal‐to‐noise ratio, non‐stationarity, and the high subject dependence of the EEG signal.
