This thesis aims at providing new knowledge on the, otherwise poorly known, molecular-scale mechanisms that operate during hydration of cement phases and dissolution of their hydrates. In order to pursue this objective, a ...
Giusto, Thomas B. J. di (Data de defensa: 2024-01-24)
(English) In the realm of Computer-Aided Engineering applied to fast solid dynamics, the intricate mechanical behaviours exhibited by materials when subjected to strong dynamic forces, high speed impacts and complex ...
Giorgiani, Giorgio (Data de defensa: 2013-04-02)
This PhD thesis proposes a p-adaptive technique for the Hybridizable Discontinuous Galerkin method (HDG). The HDG method is a novel discontinuous Galerkin method (DG) with interesting characteristics. While retaining all ...
Chevalier, Guillaume G. (Data de defensa: 2013-06-21)
Occurrence of debris flows has received little attention in the Pyrenees, probably due to the small risk faced by most of the debris-flow prone sites in this mountain range. Nevertheless, the event of Biescas, which occurred ...
Estrella Toral, Soledad (Data de defensa: 2013-10-17)
Tradicionalmente la construcción de aliviaderos escalonados en presas de hormigón compactado con rodillo (HCR) se caracteriza por la presencia de muretes guías que imponen un ancho constante a lo largo del aliviadero y que ...
Sánchez Juny, Martí (Data de defensa: 2001-05-15)
Se presentarán en este trabajo los aspectos principales del estado del conocimiento existente sobre el comportamiento hidráulico de los aliviaderos escalonados. Se analizará: la caracterización del flujo que se observa en ...
Mocci, Alice (Data de defensa: 2021-07-22)
Piezoelectricity, the two-way coupling between electric polarization and strain is the basic mechanism behind most electromechanical transduction technologies. It is possible only in a limited number of materials, namely ...
