A chaotic secure communication scheme based on duffing oscillators and frequency estimation
(2013)
Conference report
Open AccessThis work presents a new technique to securely transmit and retrieve a message signal via chaotic systems. In our system, a two-valued message signal modulates the frequency of a Duffing oscillator sinusoidal term. An ... -

A fault detection method for pitch actuators faults in wind turbines
(2015)
Conference report
Open AccessThe paper presents a model-based fault detection method for pitch actuators faults using the normalized gradient method to estimate the parameters of the pitch actuator. One major difficulty is that the input signal to the ... -
A long-short-term-memory neural network approach to early fault detection of wind turbines' main bearing based only on SCADA data.

A modified Chua chaotic oscillator and its application to secure communications
(2014)
Article
Open AccessIn this paper, a new modified Chua oscillator is introduced. The original Chua oscillator is well known for its simple implementation and mathemati- cal modeling. A modification of the oscillator is proposed in order to ... -
A review of prognostics and health management in wind turbine components
(2024-06-27)
Article
Open AccessWind turbines (WTs) play an essential role in renewable energy generation, and ensuring their reliable operation is essential for sustainable energy production and reduction of levelized cost of energy. In this context, ... -
A review of prognostics and health management techniques in wind energy
(2025-08)
Article
Open AccessThis review aims to provide a holistic understanding of prognostics and health management (PHM) techniques in wind energy, particularly in the estimation of remaining useful life (RUL) of wind turbine (WT) components. The ... -
A secure communication design based on the chaotic logistic map: an experimental realization using Arduino microcontrollers

A secure communication system based on a modified chaotic chua oscillator
(2014)
Conference lecture
Open AccessIn this paper we propose a new scheme for secure communications us- ing a modified Chua oscillator. A modification of the oscillator is proposed in order to facilitate the decryption. The communication system requires two ... -
A velocity based active vibration control of hysteretic systems
(2011-01)
Article
Open AccessHysteresis is a property of systems that do not instantly follow the forces applied to them, but react slowly, or do not return completely to their original state. A velocity based active vibration control, along with a ... -
A velocity based active vibration control of hysteretic systems
(2011)
Conference report
Open Access -
Acceleration-based fault-tolerant control design of offshore fixed wind turbines
(2016)
Article
Open AccessWind turbines (WTs) are basically controlled by varying the generator load torque (with the so-called torque control) and the blade pitch angles (with the so-called pitch control) based on measurement of the generator shaft ... -
Active control of hysteretic base-isolated structures via delayed signals
(2010)
Conference lecture

An experimental realization of a chaos-based secure communication using arduino microcontrollers
(2015-08-27)
Article
Open AccessSecurity and secrecy are some of the important concerns in the communications world. In the last years, several encryption techniques have been proposed in order to improve the secrecy of the information transmitted. ... -
Anomaly-based fault detection in wind turbine main bearings
(Copernicus Office, 2023-04-14)
Article
Open AccessRenewable energy is a clean and inexhaustible source of energy, so every year interest in the study and the search for improvements in production increases. Wind energy is one of the most used sources of energy, and therefore ... -
