Centralized Airflow Control to Reduce Output Power Variation in a Complex OWC Ocean Energy Network
(Wiley-Hindawi, 2020-08-18)
A centralized airflow control scheme for a complex ocean energy network (OEN) is proposed in this paper to reduce the output power variation (OPV). The OEN is an integrated network of multiple oscillating water columns ...
On the Use of Entropy Issues to Evaluate and Control the Transients in Some Epidemic Models
(MDPI, 2020-05-09)
This paper studies the representation of a general epidemic model by means of a first-order differential equation with a time-varying log-normal type coefficient. Then the generalization of the first-order differential ...
Variable Speed Control In Wells Turbine-Based Oscillating Water Column Devices: Optimum Rotational Speed
(IOP Publishing LTD, 2018)
The effects of climate change and global warming reveal the need to find alternative sources of clean energy. In this sense, wave energy power plants, and in particular Oscillating Water Column (OWC) devices, offer a huge ...
Optimization of the Heating System Use in Aged Public Buildings via Model Predictive Control
(MDPI, 2016-03)
This work presents the implementation of a Model Predictive Control (MPC) scheme used to study the improvement of the thermal quality in aged residential buildings without any rehabilitation. The controller manages the ...
Complementary Power Control for Doubly Fed Induction Generator-Based Tidal Stream Turbine Generation Plants
(MDPI, 2017-07)
The latest forecasts on the upcoming effects of climate change are leading to a change in the worldwide power production model, with governments promoting clean and renewable energies, as is the case of tidal energy. ...
Performance of an Ocean Energy Conversion System with DFIG Sensorless Control
(Hindawi Publishing Corporation, 2013-05)
The 2009/28/EC Directive requires Member States of the European Union to adopt a National Action Plan for Renewable Energy. In this context, the Basque Energy Board, EVE, is committed to research activities such as the ...
A Study on COVID-19 Incidence in Europe through Two SEIR Epidemic Models Which Consider Mixed Contagions from Asymptomatic and Symptomatic Individuals
(MDPI, 2021-07-06)
The impact of the SARS-CoV-2 (COVID-19) on the world has been partially controlled through different measures of social isolation and prophylaxis. Two new SEIR (Susceptible-Exposed-Infected-Recovered) models are proposed ...
On the Properties of a Class of Impulsive Competition Beverton–Holt Equations
(MDPI, 2021-09-28)
This paper is devoted to a type of combined impulsive discrete Beverton–Holt equations in ecology when eventual discontinuities at sampling time instants are considered. Such discontinuities could be interpreted as impulses ...
Reliable Control Applications with Wireless Communication Technologies: Application to Robotic Systems
(MDPI, 2021-10-26)
The nature of wireless propagation may reduce the QoS of the applications, such that some packages can be delayed or lost. For this reason, the design of wireless control applications must be faced in a holistic way to ...
Scalable IoT Architecture for Monitoring IEQ Conditions in Public and Private Buildings
(MDPI, 2022-03-21)
This paper presents a scalable IoT architecture based on the edge–fog–cloud paradigm for monitoring the Indoor Environmental Quality (IEQ) parameters in public buildings. Nowadays, IEQ monitoring systems are becoming ...
