    Structural health monitoring for offshore wind turbine foundations is paramount to the further development of offshore fixed wind farms. At present time there are a limited number of foundation designs, the jacket type ...
  • Persistence of periodic traveling waves and Abelian integrals 

    Gasull Embid, Armengol; Geyer, Anna; Mañosa Fernández, Víctor (2021-08)
    Article
    Open Access
    It is well known that the existence of traveling wave solutions (TWS) for many partial differential equations (PDE) is a consequence of the fact that an associated planar ordinary differential equation (ODE) has certain ...
  • Multidimensional data statistical processing of magnetic flow leakage signals from a Colombian gas pipeline 

    Mujica Delgado, Luis Eduardo; Ruiz Ordóñez, Magda; Villamizar Mejía, Rodolfo (2020-12-15)
    Article
    Open Access
    The hydrocarbon industry in Colombia is one of the principal pillars for the Colombian economy, representing around 5% of its gross domestic product. Since petroleum reserves have decreased, gas becomes one main alternative ...
  • Predictors of failure with high-flow nasal oxygen therapy in COVID-19 patients with acute respiratory failure: a multicenter observational study 

    Mellado Artigas, Ricard; Mujica Delgado, Luis Eduardo; Ruiz Ordóñez, Magda; Leonel Ferreyro, Bruno; Angriman, Federico; Arruti, Egoitz; Torres, Antoni; Barbeta, Enric; Villar, Jesús; Ferrando, Carlos (2021-03-05)
    Article
    Open Access
    Purpose: We aimed to describe the use of high-flow nasal oxygen (HFNO) in patients with COVID-19 acute respiratory failure and factors associated with a shift to invasive mechanical ventilation. Methods: This is a ...
  • On babuška's model for asymmetric hysteresis 

    Ikhouane, Fayçal (2021-04-01)
    Article
    Restricted access - publisher's policy
    Hysteresis is a complex phenomenon that occurs in many areas of science and engineering. To model hysteresis, scientists combine first laws of physics with fictitious equations to obtain phenomenological models that aim ...
  • A Hysteresis dynamic mathematical model approach to parametric estimation system 

    Ponce de León Puig, Nubia Ilia; Acho Zuppa, Leonardo; Rodellar Benedé, José (Hindawi, 2021-02-14)
    Article
    Open Access
    The main contribution of this paper is the proposal of a recent hysteresis dynamic model which is successfully employed within a posited signal modulator. The modulation of signals is a commonly required stage in many ...
  • Stability index of linear random dynamical systems 

    Cima Mollet, Anna; Gasull Embid, Armengol; Mañosa Fernández, Víctor (2021)
    Article
    Open Access
    Given a homogeneous linear discrete or continuous dynamical system, its stability index is given by the dimension of the stable manifold of the zero solution. In particular, for the n dimensional case, the zero solution ...
  • Wind turbine main bearing fault prognosis based solely on SCADA data 

    Encalada-Dávila, Ángel; Puruncajas Maza, Bryan; Tutivén Gálvez, Christian; Vidal Seguí, Yolanda (Multidisciplinary Digital Publishing Institute (MDPI), 2021-03-23)
    Article
    Open Access
    As stated by the European Academy of Wind Energy (EAWE), the wind industry has identified main bearing failures as a critical issue in terms of increasing wind turbine reliability and availability. This is owing to major ...

  • Wind turbine fault detection using highly imbalanced real SCADA data 

    Velandia Cardenas, Cristian; Vidal Seguí, Yolanda; Pozo Montero, Francesc (2021-03-20)
    Article
    Open Access
    Wind power is cleaner and less expensive compared to other alternative sources, and it has therefore become one of the most important energy sources worldwide. However, challenges related to the operation and maintenance ...
  • A deep learning approach for segmentation of red blood cell images and malaria detection 

    Delgado Ortet, Maria; Molina Borrás, Ángel; Alférez Baquero, Edwin Santiago; Rodellar Benedé, José; Merino González, Anna (2020-06-13)
    Article
    Open Access
    Malaria is an endemic life-threating disease caused by the unicellular protozoan parasites of the genus Plasmodium. Confirming the presence of parasites early in all malaria cases ensures species-specific antimalarial ...
  • Atypical lymphoid cells circulating in blood in COVID-19 infection: morphology, immunophenotype and prognosis value 

    Merino González, Anna; Vlagea, Alexandru; Molina Borrás, Ángel; Egri, Natalia; Laguna Moreno, Javier; Barrera Llanga, Kevin Iván; Boldú Nebot, Laura; Acevedo Lipes, Andrea; Díaz Pavón, Mar; Sibina Buron, Francesc; Bascón, Francisca; Sibila Vidal, Oriol; Juan Otero, Manel; Rodellar Benedé, José (2020-01-01)
