    Rainwater harvesting might help to achieve self-sufficiency, but it must comply with health standards. We studied the runoff quantity and quality harvested from seven urban surfaces in a university campus in Barcelona ...
  • Unified formulation of a family of iterative solvers for power systems analysis 

    Borzacchiello, Domenico; Chinesta, Francisco; Malik, Muhammad H.; García Blanco, Raquel; Díez, Pedro (2016-11)
    Article
    Accés restringit per política de l'editorial
    This paper illustrates the construction of a new class of iterative solvers for power flow calculations based on the method of Alternating Search Directions. This method is fit to the particular algebraic structure of the ...
  • Erosion caused by propeller jets in a low energy harbour basin 

    Mujal Colilles, Anna; Gironella Cobos, Xavier; Sánchez-Arcilla Conejo, Agustín; Puig i Polo, Càrol; García León, Manuel (2017-01)
    Article
    Accés restringit per política de l'editorial
    Field data of a harbour basin are compared with analytical formulations for predicting maximum scouring depth due to propeller jets. Spatial data analysis of seven-year biannual bathymetries quantifies the evolution of the ...
  • Fully coupled thermo-hydro-mechanical double-porosity formulation for unsaturated soils 

    Sánchez, Marcelo; Gens Solé, Antonio; Victoria Villar, María; Olivella Pastallé, Sebastià (2016-12)
    Article
    Accés obert
    This work presents a fully coupled formulation developed to handle engineering problems in unsaturated (and saturated) soils that present two dominant void levels. The proposed framework assumes the presence of two porous ...
  • Numerical analysis of suction embedded plate anchors in structured clay 

    Charlton, T. S.; Rouainia, M.; Gens Solé, Antonio (2016-12)
    Article
    Accés restringit per política de l'editorial
    As offshore energy developments move towards deeper water, moored floating production facilities are increasingly preferred to fixed structures. Anchoring systems are therefore of great interest to engineers working on ...
  • Velocity-based formulations for standard and quasi-incompressible hypoelastic-plastic solids 

    Franci, Alessandro; Oñate Ibáñez de Navarra, Eugenio; Carbonell Puigbó, Josep Maria (John Wiley & Sons, 2016-09)
    Article
    Accés restringit per política de l'editorial
    We present three velocity-based updated Lagrangian formulations for standard and quasi-incompressible hypoelastic-plastic solids. Three low-order finite elements are derived and tested for non-linear solid mechanics problems. ...
  • Steam curing influence on fly ash high-performance recycled concrete 

    Gonzàlez Corominas, Andreu; Etxeberria Larrañaga, Miren; Galindo, Anna (2016-11)
    Article
    Accés restringit per política de l'editorial
    High-performance concrete (HPC) mixtures were produced using 100% coarse recycled concrete aggregates (RCAs) from three different qualities. The concretes were produced using two binders: portland cement and portland cement ...
  • A numerical investigation of the incremental behavior of crushable granular soils 

    Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; Calvetti, Francesco; Gens Solé, Antonio (2016-09)
    Article
    Accés restringit per política de l'editorial
    The mechanical behavior of granular materials is characterized by strong nonlinearity and irreversibility. These properties have been differently described by a variety of constitutive models. To test any constitutive ...
  • Shock capturing techniques for hp-adaptive finite elements 

    Hierro Fabregat, Alba; Badia, Santiago; Kus, Pavel (2016-09)
    Article
    Accés restringit per política de l'editorial
    The aim of this work is to propose an hp-adaptive algorithm for discontinuous Galerkin methods that is capable to detect the discontinuities and sharp layers and avoid the spurious oscillation of the solution around them. ...
  • Assessment of inlet efficiency through a 3D simulation: numerical and experimental comparison 

    Gómez Valentín, Manuel; Recasens, Joan; Russo, Beniamino; Martínez Gomariz, Eduardo (2016-10-01)
    Article
    Accés obert
    Inlet efficiency is a requirement for characterizing the flow transfers between surface and sewer flow during rain events. The dual drainage approach is based on the joint analysis of both upper and lower drainage levels, ...
