    This contribution examines the passenger forecasting performance of the SARIMA method applied to cruise activities in the main Spanish ports. In this port system, the cruise activity market is characterized by different ...

  • Modified unit cell approach for modelling geosynthetic-reinforced column-supported embankments 

    Yu, Yan; Bathurst, Richard; Puig Damians, Ivan (2016-06)
    Article
    Open Access
    Geosynthetic-reinforced and column-supported (GRCS) embankments have proven to be an effective construction technique for fills on soft foundations. The paper introduces a modified unit cell approach to model GRCS embankments ...

  • Error estimation for proper generalized decomposition solutions: a dual approach 

    Reis, Jonatha; Moitinho de Almeida Pereira, José Paulo; Díez, Pedro; Zlotnik, Sergio (2020-12-15)
    Article
    Restricted access - publisher's policy
    The Proper Generalized Decomposition is a well established reduced order method, used to efficiently obtain approximate solutions of multi-dimensional problems in a procedure that controls the effects of the "curse of ...

  • A constitutive model for the accumulated strain of unsaturated soil under high-cycle traffic loading 

    Cao, Zhigang; Chen, Jingyu; Alonso Pérez de Agreda, Eduardo; Ramon Tarragona, Anna; Cai, Yuanqiang; Gu, Chuan; Zhang, Qi (2021-05)
    Article
    Restricted access - publisher's policy
    The road base is normally situated above the water table and thus in unsaturated state. Experimental results show that the accumulated strains of the unsaturated road base aggregate under high-cycle traffic loads are ...

  • Size effect on the hydraulic behavior of fluid flow through a single rough-walled fracture 

    Zhong, Zhen; Wang, Lei; Song, Leibo; Gao, Chao; Hu, Yunjin; Gao, Huicai; Song, Fei; Rodríguez Dono, Alfonso; Lou, Rong (Elsevier, 2021-04)
    Article
    Restricted access - publisher's policy
    This study provides a numerical approach to evaluate the effect of sample sizes on fluid flow through a single rough-walled fracture. The rough-walled fracture was generated by using mathematical statistics. Its aperture ...

  • The failure of the Aznalcóllar tailings dam in SW Spain 

    Alonso Pérez de Agreda, Eduardo (2021-03)
    Article
    Restricted access - publisher's policy
    The Aznalcóllar dyke failed and released much of its stored, saturated pyritic tailings after a process of progressive failure in the foundation clay. 1.5 Mm3 of tailings and 5.5 Mm3 of acidic water were rapidly discharged ...

  • Self-propulsion of active colloids via ion release: theory and experiments 

    Corato, Marco de; Arqué, Xavier; Patiño, Tania; Arroyo Balaguer, Marino; Sanchez Ordoñez, Samuel; Pagonabarraga, Ignacio (American Institute of Physics (AIP), 2020-03-13)
    Article
    Open Access
    We study the self-propulsion of a charged colloidal particle that releases ionic species using theory and experiments. We relax the assumptions of thin Debye length and weak nonequilibrium effects assumed in classical ...

  • Assessment of the existing models to evaluate the shear strength contribution of externally bonded FRP shear reinforcements 

    Oller Ibars, Eva; Kotynia, Renata; Marí Bernat, Antonio Ricardo (2021-01)
    Article
    Restricted access - publisher's policy
    This paper presents an analysis of the performance of different existing formulations to quantify the FRP contribution to the shear strength of RC elements strengthened in shear by externally bonded FRP sheets. A large ...

  • Problema 168 

    Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Mitjana Riera, Margarida (Real Sociedad Matemática Española, 2010)
    Article
    Open Access

  • A time averaged steady state method for the Navier-Stokes equations 

    Zhao, Mengjie; Zorrilla Martínez, Rubén; Rossi, Riccardo; Wüchner, Roland (2021-02)
    Article
    Open Access
    This work derives an incompressible Variational Multiscales time-averaged Navier-Stokes formulation that aims at obtaining accurate steady state solutions. Rather than using the standard time instantaneous velocity and ...

  • Detection of damage using temporal variation in natural frequencies and principal component analysis 

    Caselles Magallón, Josep Oriol; Martín, Aleix; Clapes Boixader, Jaime (2020-11)
    Article
    Restricted access - publisher's policy
    Detection of structural damage is an important issue. Some techniques require knowledge of the undamaged state or in-depth knowledge of the construction materials used. The application of principal component analysis to ...

  • Extension of the ζ‐method for calculating deflections of two‐way slabs based on linear elastic finite element analysis 

    Tošić, Nikola; Pecic, Nenad; Poliotti, Mauro; Marí Bernat, Antonio Ricardo; Torres Llinàs, Lluís; Dragaš, Jelena (Wiley (John Wiley & Sons), 2021-02)
    Article
    Restricted access - publisher's policy
    Deflections are among the most complex aspects of reinforced concrete behavior. Furthermore, deflection control is increasingly a governing criterion in design, especially in the case of two‐way members such as flat slabs ...
