O sector da construción en Galicia: responsabilidade social empresarial e resultados financeiros
(Universidade de Santiago de Compostela, 2019)
[Resumo] A Responsabilidade Social da Empresa (RSE), tamén denominada Responsabilidade Social Corporativa (RSC), formúlase como un factor estratéxico clave na xestión. O obxecto deste traballo é analizar as relacións ...
WENO Schemes on Unstructured Meshes Using a Relaxed a Posteriori MOOD Limiting Approach
(Elsevier, 2020)
[Abstract] In this paper a relaxed formulation of the a posteriori Multi-dimensional Optimal Order Detection (MOOD) limiting approach is introduced for weighted essentially non-oscillatory (WENO) finite volume schemes on ...
A Mathematical Model to Evaluate the Impact of the Maintenance Strategy on the Service Life of Flexible Pavements
(Hindawi, 2019)
[Abstract] The structural failure of a flexible pavement occurs when the accumulated fatigue damage produced by all the vehicles that have passed over each section exceeds a certain threshold. For this reason, the service ...
A very accurate Arbitrary Lagrangian–Eulerian meshless method for Computational Aeroacoustics
(Elsevier, 2018)
[Abstract:] In this work, we propose a new meshless approach based on a Galerkin discretization of a set of conservation equations on an Arbitrary Lagrangian–Eulerian framework. In particular, we solve the Linearized Euler ...
A Higher‑Order Chimera Method for Finite Volume Schemes
(Springer, 2018)
[Abstract:] In this work a higher-order accurate finite volume method for the resolution of the Euler/Navier–Stokes equations using Chimera grid techniques is presented. The formulation is based on the use of Moving Least ...
An a posteriori, efficient, high-spectral resolution hybrid finite-difference method for compressible flows
(Elsevier, 2018)
[Abstract:] A high-order hybrid method consisting of a high-accurate explicit finite-difference scheme and a Weighted Essentially Non-Oscillatory (WENO) scheme is proposed in this article. Following this premise, two ...
On g-barrelled groups and their permanence properties
(Elsevier, 2019)
[Abstract:] The g-barrelled groups constitute a vast class of abelian topological groups. It might be considered as a natural extension of the class of barrelled topological vector spaces. In this paper we prove that ...
On local cross sections in topological abelian groups
(Springer, 2018)
[Abstract:] We introduce the notion of local pseudo-homomorphism between two topological abelian groups. We prove that it is closely related with the widely studied notions of local cross sections and splitting extensions ...
A reduced-dissipation WENO scheme with automatic dissipation adjustment
(Elsevier, 2020)
[Abstract:] In this paper, we propose a novel modification to the WENO-family schemes to reduce its intrinsic dissipation. In this work, we focus on the WENO5 scheme, which is rewritten in terms of a central plus a dissipative ...
Numerical assessment of fan blades screen effect on fan/OGV interaction tonal noise
(Elsevier, 2020)
[Abstract:] This work deals with sound generation and transmission in a fan stage. The study is done on a subsonic Fan stage and interaction noise between the fan wakes and the Outlet Guide Vanes (OGV) is considered. For ...
