A count invariant for Lambek calculus with additives and bracket modalities
(Springer-Verlag Berlin Heidelberg, 2013)
Text en actes de congrés
Accés restringit per política de l'editorialThe count invariance of van Benthem (1991) is that for a sequent to be a theorem of the Lambek calculus, for each atom, the number of positive occurrences equals the number of negative occurrences. (The same is true ... -
A coupled analysis of sloshing in floating structures by integrating moving particle semi-implicit (MPS) method with a time domain multibody dynamic analysis software
(CIMNE, 2013)
Text en actes de congrés
Accés obertSloshing effects inside partially filled tanks on LNG carriers and FPSOs motions cannot be ignored. It is necessary to analyze the floating structures motion with the sloshing behavior simultaneously to obtain more accurate ... -
A coupled and multi-scale fluid-structure interaction and mass transfer model for biofilm growth simulations
(CIMNE, 2013)
Text en actes de congrés
Accés obertThe formation and development of different biofilm structures is known to be influenced by nutrients availability and flow conditions. For this reason an approach which takes in account the effect of local structure ... -
A coupled damage-elastoplasticity approach for cemented soils
(Universitat Politècnica de Catalunya, 2019-06)
Projecte Final de Màster Oficial
Accés obertGranular materials may experiment a process of cementation either artificially, as, for example, in the case of cement treated earth, or resulting from natural processes as for instance carbonate or silicate deposition. ... -
A coupled discrete-element model of fluid-saturated rock and the results of studying of the impact of a fluid on the shear strength of a rock under combined compression and shear
(CIMNE, 2017)
Text en actes de congrés
Accés obertWithin a discrete-element model of a porous permeable elastic-plastic rock, filled with a fluid, we have studied the shear strength of a fractured interface zone (a shear band) between blocks of a geological medium subject ... -
A coupled Eulerian-PFEM model for the simulation of overtopping in rockfill dams
(Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2012)
Llibre

A coupled Eulerian-PFEM model for the simulation of overtopping in rockfill dams
(Universitat Politècnica de Catalunya, 2012-07-05)
Tesi
Accés obertRockfill dams are nowadays often preferred over concrete dams because of their economic advantages, their flexible design and thank to the great advance achieved in geosciences and geomechanics. Unfortunately their behavior ... -
A coupled fluid FEM-DEM technique for predicting blasting operations in tunnels
(2018-12)
Article
Accés obertWe present recent developments in the coupling of the finite element method (FEM) and the discrete element method (DEM) for the analysis of rock blasting operations in tunnels. The coupled FEM-DEM technique has been proven ... -

Text en actes de congrés
Accés obertAn efficient computational procedure is presented for the solution of coupled hydroelastic problems involving bodies of general thickness, floating over variable bathymetry regions. The problem is treated by the coupled ... -
A coupled model of mechanical behaviour and water retention for unsaturated soils with double porosity
(CIMNE, 2011)
Text en actes de congrés
Accés obertMany natural soils and engineering geomaterials, such as aggregated soils and compacted clay pallets, exhibit two levels of porosity corresponding to the inter- and intraaggregate pores within their hierarchical structure. ... -
