  • 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 Cacalló, 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: ...
  • A wind turbine blade damage detection system based on data analysis: an academic xample on the use of histograms 

    Acho Zuppa, Leonardo; Buenestado Caballero, Pablo (2018)
    Conference report
    Restricted access - publisher's policy
    The main objective of this paper is to introduce an academic example on the use of histograms to develop a wind turbine blade fault (or damage) detection system. This approach merely uses data analysis obtained from a ...
  • An effective strategy of real-time vision-based control for a Stewart platform 

    Rossell Garriga, Josep Maria; Vicente Rodrigo, Jesús; Rubió Massegú, Josep; Barcons Xixons, Víctor (2018)
    Conference report
    Open Access
    A Stewart platform is a kind of parallel robot which can be used for a wide variety of technological and industrial applications. In this paper, a Stewart platform designed and assembled at the Universitat Polit`ecnica de ...
  • 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 ...

  • Damage and fault detection of structures using principal component analysis and hypothesis testing 

    Pozo Montero, Francesc; Vidal Seguí, Yolanda (Springer, 2017-12-13)
    Part of book or chapter of book
    Restricted access - publisher's policy
    This chapter illustrates the application of principal component analysis (PCA) plus statistical hypothesis testing to online damage detection in structures, and to fault detection of an advanced wind turbine benchmark under ...
  • Periodic points of a Landen transformation 

    Gasull Embid, Armengol; Llorens, Mireia; Mañosa Fernández, Víctor (2018-01-12)
    External research report
    Open Access
    We prove the existence of 3-periodic orbits in a dynamical system associated to a Landen transformation previously studied by Boros, Chamberland and Moll, disproving a conjecture on the dynamics of this planar map introduced ...
  • Parrondo's dynamic paradox for the stability of non-hyperbolic fixed points 

    Cima Mollet, Anna; Gasull Embid, Armengol; Mañosa Fernández, Víctor (2018-02)
    Article
    Restricted access - publisher's policy
    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 ...
