Fluid–structure interaction analysis of eccentricity and leaflet rigidity on thrombosis biomarkers in bioprosthetic aortic valve replacements
(John Wiley & sons, 2022-09-15)
Article
Open AccessThis work intends to study the effect of aortic annulus eccentricity and leaflet rigidity on the performance, thrombogenic risk and calcification risk in bioprosthetic aortic valve replacements (BAVRs). To address these ... -
The geometry of Hermitian self-orthogonal codes
(Springer, 2021-12-20)
Article
Restricted access - publisher's policyWe prove that if n>k2 then a k-dimensional linear code of length n over Fq2 has a truncation which is linearly equivalent to a Hermitian self-orthogonal linear code. In the contrary case we prove that truncations of linear ... -
Two-dimensional Riemann problem for rigid representations on an elliptic curve
(2017-04-01)
Article
Open AccessWe consider a generalization of Riemann–Hilbert problem on elliptic curves. For a given elliptic curve and irreducible representation of free group with two generators we construct explicitly a semistable vector bundle of ... -
An appropriate index to assess the global cancellation level of the harmonic currents consumed by a set of single-phase uncontrolled rectifiers and a set of fluorescent lamps
(2022-06-13)
Article
Open AccessAn in-depth study of harmonic current reduction in European commercial buildings due to the harmonic cancellation effect when a set of single-phase uncontrolled rectifiers and a set of fluorescent lamps are connected at ... -
Methodology for obtaining simplified models for the long-term energy management of renewable assets under a high degree of uncertainty
(Elsevier, 2022-11)
Article
Open AccessThis paper addresses the attainment of a methodology aimed at obtaining simplified models embedding the regulatory constraints imposed by the country-specific remuneration mechanisms in the energy management system of long ... -
Determining when a truncated generalised Reed-Solomon code is Hermitian self-orthogonal
(Institute of Electrical and Electronics Engineers (IEEE), 2022-02-09)
Article
Open AccessWe prove that there is a Hermitian self-orthogonal k -dimensional truncated generalised Reed-Solomon code of length n¿q2 over Fq2 if and only if there is a polynomial g¿Fq2 of degree at most (q-k)q-1 such that g+gq has ... -
An inextensible model for the robotic manipulation of textiles
(2022-01-01)
Article
Open AccessWe introduce a new isometric strain model for the study of the dynamics of cloth garments in a moderate stress environment, such as robotic manipulation in the neighborhood of humans. This model treats textiles as surfaces ... -
A K-contact Lagrangian formulation for nonconservative field theories
(2021-06-01)
Article
Restricted access - publisher's policyDynamical systems with dissipative behaviour can be described in terms of contact manifolds and a modified version of Hamilton's equations. Dissipation terms can also be added to field equations, as showed in a recent paper ... -
Skinner–Rusk formalism for k-contact systems
(2022-02-01)
Article
Open AccessIn previous papers, a geometric framework has been developed to describe non-conservative field theories as a kind of modified Lagrangian and Hamiltonian field theories. This approach is that of k-contact Hamiltonian ... -
Limiting probabilities of first order properties of random sparse graphs and hypergraphs
(2021-08-18)
Article
Open AccessLet Gn be the binomial random graph G(n, p = c/n) in the sparse regime, which as is well-known undergoes a phase transition at c = 1. Lynch (Random Structures Algorithms, 1992) showed that for every first order sentence ... -
Probabilities of first-order sentences on sparse random relational structures: An application to definability on random CNF formulas
(Oxford University Press, 2021-03-01)
Article
Open AccessWe extend the convergence law for sparse random graphs proven by Lynch to arbitrary relational languages. We consider a finite relational vocabulary s and a first-order theory T for s composed of symmetry and anti-reflexivity ... -
R-LWE-Based distributed key generation and threshold decryption
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-02-25)
Article
Open AccessEver since the appearance of quantum computers, prime factoring and discrete logarithm based cryptography has been put in question, giving birth to the so called post-quantum cryptography. The most prominent field in ...
