  • System identification of a class of Wiener systems with hysteretic nonlinearities 

    radouane, Abdelhadi; Giri, Fouad; Ikhouane, Fayçal; Ahmed-Ali, Tarek; Chaoui, Fatima Zahra; Brouri, Adil (2017-03-01)
    Article
    Accés restringit per política de l'editorial
    Existing works on Wiener system identification have essentially been focused on the case where the output nonlinearity is memoryless. When memory nonlinearities have been considered, the focus has been restricted to backlash ...
  • Detection and classification of structural changes using artificial immune systems and fuzzy clustering 

    Anaya, Maribel; Tibaduiza Burgos, Diego Alexander; Pozo Montero, Francesc (2017-01-01)
    Article
    Accés restringit per política de l'editorial
    Among all the elements that are integrated into a structural health monitoring (SHM) system, methods or strategies for damage detection and classification are nowadays playing a key role in enhancing the operational ...
  • Temperature robust PCA based stress monitoring approach 

    Quiroga, Jabid; Quiroga, John; Mujica Delgado, Luis Eduardo; Villamizar Mejía, Rodolfo; Ruiz Ordóñez, Magda (2016-09-30)
    Article
    Accés obert
    In this paper, a guided wave temperature robust PCA-based stress monitoring methodology is proposed. It is based on the analysis of the longitudinal guided wave propagating along the path under stress. Slight changes in ...
  • Flow estimation in a steel pipe using guided waves 

    Quiroga, John; Quiroga, Jabid; Mujica Delgado, Luis Eduardo; Villamizar Mejía, Rodolfo; Ruiz Ordóñez, Magda (2016-09-30)
    Article
    Accés obert
    In this investigation, a flow rate estimation guided wave based scheme in pipes is proposed. The effect of the fluid over the propagation of longitudinal waves has been experimentally studied by using several laminar ...
  • A velocity based active vibration control of hysteretic systems 

    Pujol Vázquez, Gisela; Acho Zuppa, Leonardo; Pozo Montero, Francesc; Rodriguez, Arturo; Vidal Seguí, Yolanda (2011-01)
    Article
    Accés obert
    Hysteresis is a property of systems that do not instantly follow the forces applied to them, but react slowly, or do not return completely to their original state. A velocity based active vibration control, along with a ...
  • Integrated design of hybrid interstory-interbuilding multi-actuation schemes for vibration control of adjacent buildings under seismic excitations 

    Palacios Quiñonero, Francisco; Rubió Massegú, Josep; Rossell Garriga, Josep Maria; Karimi, Hamid Reza (Multidisciplinary Digital Publishing Institute, 2017-03-25)
    Article
    Accés obert
    The design of vibration control systems for the seismic protection of closely adjacent buildings is a complex and challenging problem. In this paper, we consider distributed multi-actuation schemes that combine interbuilding ...
  • Evaluation of piezodiagnostics approach for leaks detection in a pipe loop 

    Camacho-Navarro, Jhonatan; Ruiz Ordóñez, Magda; Villamizar Mejía, Rodolfo; Mujica Delgado, Luis Eduardo; Pérez, Oscar (2016-09-30)
    Article
    Accés obert
    Pipe leaks detection has a great economic, environmental and safety impact. Although several methods have been developed to solve the leak detection problem, some drawbacks such as continuous monitoring and robustness ...
