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 ...
Application of Entropy and Fractal Dimension Analyses to the Pattern Recognition of Contaminated Fish Responses in Aquaculture
(MDPI, 2014-11)
The objective of the work was to develop a non-invasive methodology for image acquisition, processing and nonlinear trajectory analysis of the collective fish response to a stochastic event. Object detection and motion ...
Shannon Entropy in a European Seabass (Dicentrarchus labrax) System during the Initial Recovery Period after a Short-Term Exposure to Methylmercury
(MDPI, 2016-05)
Methylmercury (MeHg) is an environmental contaminant of increasing relevance as a seafood safety hazard that affects the health and welfare of fish. Non-invasive, on-line methodologies to monitor and evaluate the behavior ...
Enhanced Flexibility and Reusability through State Machine-Based Architectures for Multisensor Intelligent Robotics
(MDPI, 2017-05-31)
This paper presents a state machine-based architecture, which enhances the flexibility and reusability of industrial robots, more concretely dual-arm multisensor robots. The proposed architecture, in addition to allowing ...
Automatic Analysis of Archimedes’ Spiral for Characterization of Genetic Essential Tremor Based on Shannon’s Entropy and Fractal Dimension
(MDPI, 2018-07)
Among neural disorders related to movement, essential tremor has the highest prevalence; in fact, it is twenty times more common than Parkinson's disease. The drawing of the Archimedes' spiral is the gold standard test to ...
Discrete Cosine Transform for the Analysis of Essential Tremor
(Frontiers Media, 2019-01-17)
Essential tremor (ET) is the most common movement disorder. In fact, its prevalence is about 20 times higher than that of Parkinson's disease. In addition, studies have shown that a high percentage of cases, between 50 and ...
On the Selection of Non-Invasive Methods Based on Speech Analysis Oriented to Automatic Alzheimer Disease Diagnosis
(MDPI, 2013-05)
The work presented here is part of a larger study to identify novel technologies and biomarkers for early Alzheimer disease (AD) detection and it focuses on evaluating the suitability of a new approach for early AD diagnosis ...
