  • Causal canonical decomposition of hysteresis systems 

    Ikhouane, Fayçal (2020-10-01)
    Article
    Restricted access - publisher's policy
    Hysteresis is a special type of behavior found in many areas including magnetism, mechanics, bi-ology, economics, etc. One of the characteristics of hysteresis systems is that they are approximatelyrate independent for ...
  • Damage diagnosis for offshore wind turbine foundations based on the fractal dimension 

    Hoxha, Ervin; Vidal Seguí, Yolanda; Pozo Montero, Francesc (2020-10-05)
    Article
    Open Access
    Cost-competitiveness of offshore wind depends heavily in its capacity to switch preventive maintenance to condition-based maintenance. That is, to monitor the actual condition of the wind turbine (WT) to decide when and ...
  • Structural health monitoring and condition monitoring applications: sensing, distributed communication and processing 

    Pozo Montero, Francesc; Tibaduiza Burgos, Diego Alexander; Torres Arredondo, Miguel Ángel; Varón, Margarita; Ceron-Muñoz, Hernán Darío (SAGE PUBLICATIONS INC, 2020-09-29)
    Article
    Open Access
    Structural health monitoring (SHM) is a wide area of engineering that focuses on the verification of the state or health of structures in order to ensure proper perfor- mance using nondestructive tests, involving sensors ...
  • Relevancia de la onicodistrofia en pacientes con alteración venosa crónica

    Open Access
    Objetivo: El propósito fue evaluar la relación entre onicodistrofia y la alteración venosa crónica. Material y métodos: Se realizó un estudio observacional y transversal con 83 pacientes entre 40 y 84 años afectados de ...
  • Adaptive self-recurrent wavelet neural network and sliding mode controller/observer for a slider crank mechanism 

    Azar, Ahmad T.; Serrano, Fernando E.; Rossell Garriga, Josep Maria; Vaidyanathan, Sundarapandian; Zhu, Quanmin (InderScience Publishers, 2020-10-03)
    Article
    Restricted access - publisher's policy
    In this paper, a novel control strategy based on an adaptive Self-Recurrent Wavelet Neural Network (SRWNN) and a sliding mode controller/observer for a slider crank mechanism is proposed. The aim is to reduce the tracking ...
  • Temperature prediction model in the main ventilation system of an underground mine 

    Bascompta Massanes, Marc; Rossell Garriga, Josep Maria; Sanmiquel Pera, Lluís; Anticoi Sudzuki, Hernán Francisco (Multidisciplinary Digital Publishing Institute, 2020-10-16)
    Article
    Open Access
    A model to forecast the underground temperature in a mine ventilation circuit was developed on the basis of a case study and actual data describing temperature, airflow, and drift length collected over several years. A ...
  • Vibration-Response-Only Structural Health Monitoring for Offshore Wind Turbine Jacket Foundations via Convolutional Neural Networks 

    Puruncajas Maza, Bryan; Vidal Seguí, Yolanda; Tutivén Gálvez, Christian (Multidisciplinary Digital Publishing Institute (MDPI), 2020-06)
    Article
    Open Access
    This work deals with structural health monitoring for jacket-type foundations of offshore wind turbines. In particular, a vibration-response-only methodology is proposed based on accelerometer data and deep convolutional ...
  • A novel iterative linear matrix inequality design procedure for passive inter-substructure vibration control 

    Rubió Massegú, Josep; Palacios Quiñonero, Francisco; Rossell Garriga, Josep Maria; Karimi, Hamid Reza (Multidisciplinary Digital Publishing Institute, 2020-08-24)
    Article
    Open Access
    In vibration control of compound structures, inter-substructure damper (ISSD) systems exploit the out-of-phase response of different substructures to dissipate the kinetic vibrational energy by means of inter-substructure ...
  • Low-cost, open-source mechanical ventilator with pulmonary monitoring for COVID-19 patients 

    Acho Zuppa, Leonardo; Vargas, Alessandro N.; Pujol Vázquez, Gisela (MDPI AG, 2020-09-12)
    Article
    Open Access
    This paper shows the construction of a low-cost, open-source mechanical ventilator. The motivation for constructing this kind of ventilator comes from the worldwide shortage of mechanical ventilators for treating COVID-19 ...
  • Nonlinear feature extraction through manifold learning in an electronic tongue classification task 

    Leon-Medina, Jersson Xavier; Anaya Vejar, Maribel; Pozo Montero, Francesc; Tibaduiza Burgos, Diego Alexander (Multidisciplinary Digital Publishing Institute (MDPI), 2020-08-27)
    Article
    Open Access
    A nonlinear feature extraction-based approach using manifold learning algorithms is developed in order to improve the classification accuracy in an electronic tongue sensor array. The developed signal processing methodology ...
  • A dynamic Parrondo's paradox for continuous seasonal systems 

    Cima Mollet, Anna; Gasull Embid, Armengol; Mañosa Fernández, Víctor (2020-04-29)
    Article
    Restricted access - publisher's policy
    We show that planar continuous alternating systems, which can be used to model systems with seasonality, can exhibit a type of Parrondo’s dynamic paradox, in which the stability of an equilibrium, common to all seasons is ...
  • Low-speed bearing fault diagnosis based on permutation and spectral entropy measures 

    Sandoval, Diego; Leturiondo, Urko; Pozo Montero, Francesc; Vidal Seguí, Yolanda (2020-07-06)
    Article
    Open Access
    Despite its influence on wind energy service life, condition-based maintenance is still challenging to perform. For offshore wind farms, which are placed in harsh and remote environments, damage detection is critically ...
