An Arbitrary Lagrangian-Eulerian SPH-MLS Method for the Computation of Compressible Viscous Flows
(Elsevier, 2022)[Abstract] In this work we present a high-accurate discretization to solve the compressible Navier-Stokes equations using an Arbitrary Lagrangian-Eulerian meshless method (SPH-MLS), which can be seen as a general formulation ... -
Krein’s theorem in the context of topological abelian groups
(MDPI, 2022)[Abstract:] A topological abelian group G is said to have the quasi-convex compactness property (briefly, qcp) if the quasi-convex hull of every compact subset of G is again compact. In this paper we prove that there exist ... -
Topological Groups of Lipschitz Functions and Graev Metrics
(Elsevier, 2022)[Abstract] We study the properties of the free abelian topological group Ad(X) on a metric space (X,d) endowed with the topology generated by the Graev extension dˆ of a given metric d on X. We find that the group of ... -
On Local Quasi-Convexity as a Three-Space Property in Topological Abelian Groups
(Elsevier, 2021)[Abstract] Let X be a topological abelian group and H a subgroup of X. We find conditions under which local quasi-convexity of both H and results in the same property for X. This is true for instance if H is precompact, ... -
Numerical Analysis and Safety Design of Grounding Systems in Underground Compact Substations
(Elsevier, 2022)[Abstract] This paper presents a mathematical and numerical formulation to design and analyze grounding systems in underground electrical substations. The developed approach is based on the well known Maxwell’s Equations. ...
