  • Fault detection algorithm for wind turbines’ pitch actuator systems 

    Pujol Vázquez, Gisela; Acho Zuppa, Leonardo; Gibergans Bàguena, José (2020-06-04)
    Article
    Open Access
    A fault detection innovation to wind turbines’ pitch actuators is an important subject to guarantee the efficiency wind energy conversion and long lifetime operation of these rotatory machines. Therefore, a recent and ...
  • An Adaptive Predictive control scheme with dynamic Hysteresis Modulation applied to a DC-DC buck converter 

    Ponce de León Puig, Nubia Ilia; Bozalakov, Dimitar; Acho Zuppa, Leonardo; Vandevelde, Lieven; Rodellar Benedé, José (2020-05-18)
    Article
    Restricted access - publisher's policy
    This article proposes a recent Adaptive Predictive (AP) control technique applied to a DC-DC buck converter. This converter topology has a wide range of applications in the current electronic and electrical systems that ...
  • Structural health monitoring for jacket-type offshore wind turbines: experimental proof of concept 

    Vidal Seguí, Yolanda; Aquino, Gabriela; Pozo Montero, Francesc; Gutiérrez Arias, José Elegio Moisés (Multidisciplinary Digital Publishing Institute (MDPI), 2020)
    Article
    Open Access
    Structural health monitoring for offshore wind turbines is imperative. Offshore wind energy is progressively attained at greater water depths, beyond 30 m, where jacket foundations are presently the best solution to cope ...
  • PCA based stress monitoring of cylindrical specimens using PZTs and guidedwaves 

    Quiroga Méndez, Jabid; Mujica Delgado, Luis Eduardo; Villamizar Mejía, Rodolfo; Ruiz Ordóñez, Magda; Camacho Navarro, Jhonatan (Multidisciplinary Digital Publishing Institute (MDPI), 2017-12)
    Article
    Open Access
    Since mechanical stress in structures affects issues such as strength, expected operational life and dimensional stability, a continuous stress monitoring scheme is necessary for a complete integrity assessment. Consequently, ...
  • Analysis of occupational accidents in underground and surface mining in Spain using data-mining techniques 

    Sanmiquel Pera, Lluís; Bascompta Massanes, Marc; Rossell Garriga, Josep Maria; Anticoi Sudzuki, Hernán Francisco; Guasch Cascallo, Eduard (2018-03-07)
    Article
    Open Access
    An analysis of occupational accidents in the mining sector was conducted using the data from the Spanish Ministry of Employment and Social Safety between 2005 and 2015, and data-mining techniques were applied. Data was ...
  • Characterization and automatic screening of reactive and abnormal neoplastic B lymphoid cells from peripheral blood 

    Alférez Baquero, Edwin Santiago; Merino González, Anna; Bigorra López, Laura; Rodellar Benedé, José (2016-04)
    Article
    Open Access
    The objective was to advance in the automatic, image-based, characterization and recognition of a heterogeneous set of lymphoid cells from peripheral blood, including normal, reactive, and five groups of abnormal lymphocytes: ...
  • Wind turbine fault detection and classification by means of image texture analysis 

    Ruiz Ordóñez, Magda; Mujica Delgado, Luis Eduardo; Alférez Baquero, Edwin Santiago; Acho Zuppa, Leonardo; Tutivén Gálvez, Christian; Vidal Seguí, Yolanda; Rodellar Benedé, José; Pozo Montero, Francesc (2018-07)
    Article
    Open Access
    The future of the wind energy industry passes through the use of larger and more flexible wind turbines in remote locations, which are increasingly offshore to benefit stronger and more uniform wind conditions. The cost ...
  • Design of distributed multi-actuator systems with incomplete state information for vibration control of large structures 

    Palacios Quiñonero, Francisco; Rubió Massegú, Josep; Rossell Garriga, Josep Maria; Rodellar Benedé, José (Multidisciplinary Digital Publishing Institute, 2018-02)
    Article
    Open Access
    In this paper, we investigate the design and performance of static feedback controllers with partial-state information for the seismic protection of tall buildings equipped with incomplete multi-actuation systems. The ...
  • Is it better to use gate opening as control variable than discharge to control irrigation canals? 

    Horváth, Klaudia; Galvis Restrepo, Eduard; Gómez Valentín, Manuel; Rodellar Benedé, José (2015-03)
    Article
    Open Access
    Centralized model predictive controllers are common in water systems. The control action variable can be the discharge, and the subsystems (canal pools) are modeled separately. This paper focuses on short canal pools where ...
  • Analysis and synthesis of control systems over wireless digital channels 

    Reza Karimi, Hamid; Niu, Yugang; Rossell Garriga, Josep Maria; Yang, Fuwen (2017-06-01)
    Article
    Open Access
  • Parrondo's dynamic paradox for the stability of non-hyperbolic fixed points 

    Cima Mollet, Anna; Gasull Embid, Armengol; Mañosa Fernández, Víctor (2018-02)
    Article
    Open Access
    We show that for periodic non-autonomous discrete dynamical systems, even when a common fixed point for each of the autonomous associated dynamical systems is repeller, this fixed point can became a local attractor for ...
  • Image segmentation based on statistical confidence intervals 

    Buenestado Caballero, Pablo; Acho Zuppa, Leonardo (2018-01-11)
    Article
    Open Access
    Image segmentation is defined as a partition realized to an image into homogeneous regions to modify it into something that is more meaningful and softer to examine. Although several segmentation approaches have been ...
