  • Towards a standard typology of endogenous landslide seismic sources 

    Provost, Floriane; Malet, Jean-Philippe; Hibert, Clément; Abanco Martínez de Arenzana, Claudia; Hurlimann Ziegler, Marcel (European Geosciences Union (EGU), 2018-10)
    Article
    Accés obert
    The objective of this work is to propose a standard classification of seismic signals generated by gravitational processes and detected at close distances (<1 km). We review the studies where seismic instruments have been ...
  • Computational design of locally resonant acoustic metamaterials 

    Roca Cazorla, David; Yago Llamas, Daniel; Cante Terán, Juan Carlos; Lloberas Valls, Oriol; Oliver Olivella, Xavier (2019-03)
    Article
    Accés restringit per política de l'editorial
    The so-called Locally Resonant Acoustic Metamaterials (LRAM) are considered for the design of specifically engineered devices capable of stopping waves from propagating in certain frequency regions (bandgaps), this making ...
  • Multi-temporal analysis of morphologic changes applying geomatic techniques: 70 years of torrential activity in the Rebaixader catchment (Central pyrenees) 

    Núñez Andrés, María Amparo; Buill Pozuelo, Felipe; Hurlimann Ziegler, Marcel; Abanco Martínez de Arenzana, Claudia (2019-01)
    Article
    Accés obert
    The monitoring of morphologic changes in high-mountain environments is an important, but complex task. Terrestrial as well as airborne laser scanning (TLS and ALS) and digital photogrammetry (DP) using Unnamed Aerial Vehicle ...
  • Balances: a new perspective for microbiome analysis 

    Rivera Pinto, J.; Egozcue Rubí, Juan José; Pawlowsky Glahn, Vera; Paredes, Raul; Noguera Julian, Marc; Calle, M. L. (2018-07)
    Article
    Accés obert
    High-throughput sequencing technologies have revolutionized microbiome research by allowing the relative quantification of microbiome composition and function in different environments. In this work we focus on the ...
  • Incidental potable water reuse in a Catalonian basin: living downstream 

    Mujeriego Sahuquillo, Rafael; Gullón Santos, Martín; Lobato, S. (2017-09)
    Article
    Accés obert
    A preliminary assessment of incidental potable water reuse (IPR) in the Llobregat River basin has been conducted by estimating the dilution factor of treated effluent discharges upstream of six river flow measurement ...
  • Análisis no lineal de tanques criogénicos bajo cargas térmicas 

    Oliver Olivella, Xavier; Oñate Ibáñez de Navarra, Eugenio; Peraire Guitart, Jaume; Chueca Castedo, Rosa Mariana (1985-04)
    Article

  • Dynamic elastic properties of brick masonry constituents 

    Makoond, Nirvan Chandra; Pelà, Luca; Molins i Borrell, Climent (Elsevier, 2019-02)
    Article
    Accés restringit per política de l'editorial
    When subjected to dynamic loading, materials can exhibit a mechanical behaviour quite different from its static counterpart. The evaluation of dynamic properties is thus very useful in the assessment of existing masonry ...
  • Mixed aggregated finite element methods for the unfitted discretization of the Stokes problem 

    Badia, Santiago; Martín Huertas, Alberto Francisco; Verdugo Rojano, Francesc (2018-12-18)
    Article
    Accés obert
    In this work, we consider unfitted finite element methods for the numerical approximation of the Stokes problem. It is well-known that these kinds of methods lead to arbitrarily ill-conditioned systems and poorly approximated ...
  • Contribution of externally bonded FRP shear reinforcement to the shear strength of RC beams 

    Oller Ibars, Eva; Pujol Sánchez, Mireia; Marí Bernat, Antonio Ricardo (Elsevier, 2019-05)
    Article
    Accés restringit per política de l'editorial
    An experimental program of T-beams strengthened in shear by CFRP sheets has been developed with two longitudinal reinforcement ratios and different externally bonded CFRP shear strengthening amounts in a discontinuous or ...
  • Numerical simulation of the undrained stability of slopes in anisotropic fine-grained soils 

    Conesa, Sergi; Mánica Malcom, Miguel Ángel; Gens Solé, Antonio; Huang, Y. (2019-01)
    Article
    Accés restringit per política de l'editorial
    The undrained stability of slopes in anisotropic fine-grained soils is studied in this paper using the finite element method (FEM). A constitutive model is presented, able to account for the observed variation of undrained ...
  • Morphodynamics of a width-variable gravel bed stream: new insights on pool-riffle formation from physical experiments 

    Chartrand, Shawn M.; Jellinek, A. Mark; Hassan, Marwan A.; Ferrer Boix, Carles (American Geophysical Union (AGU), 2018-11)
    Article
    Accés restringit per política de l'editorial
    Field observations, experiments, and numerical simulations suggest that pool-riffles along gravel bed mountain streams develop due to downstream variations of channel width. Where channels narrow, pools are observed, and ...
  • Grading evolution and critical state in a discrete numerical model of Fontainebleau sand 

    Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; O'Sullivan, Catherine; Gens Solé, Antonio; Liu, T. (Thomas Telford, 2019-01)
    Article
    Accés restringit per política de l'editorial
    Granular materials reach critical states upon shearing. The position and shape of a critical state line (CSL) in the compression plane are important for constitutive models, interpretation of in situ tests and liquefaction ...
