An invariant based transversely-isotropic constitutive model for unidirectional fibre reinforced composites considering the matrix viscous effects
(2019-11)
Article
Accés obertFibres Reinforced Polymers (FRPs) are found in several applications in aeronautics, space and in the automotive industry. These applications are exposed to loading conditions, including impact, which results in a complex ... -
An invasive and a noninvasive approach for the automatic differentiation of obstructive and central hypopneas
(2010-04-15)
Article
Accés obertThe automatic differentiation of obstructive and central respiratory events is a major challenge in the diagnosis of sleep-disordered breathing. Esophageal pressure (Pes) measurement is the gold-standard method to ... -

An inverse approach for the mechanical characterisation of vascular tissues via a generalised rule of mixtures
(Gordon and Breach Science Publishers, 2012-12)
Article
Accés restringit per política de l'editorialMechanical factors such as stresses and strains play a major role in the growth and remodelling of soft biological tissues. The main constituents of tissue undergo different processes reacting to mechanical stimulus. ... -
An inverse Jacobian algorithm for Picard curves
(Springer, 2021-06-01)
Article
Accés obertWe study the inverse Jacobian problem for the case of Picard curves over C. More precisely, we elaborate on an algorithm that, given a small period matrix O¿C3×3 corresponding to a principally polarized abelian threefold ... -
