Una formulación numérica general para el cálculo y diseño de tomas de tierra en grandes instalaciones eléctricas 

Colominas, Ignasi; Navarrina, F.; Casteleiro, Manuel (Universitat Politècnica de Catalunya, 1997)
[Resumen] La puesta a tierra de una instalación eléctrica es imprescindible para garantizar su seguridad cuando tienen lugar situaciones de fallo. Para su correcto análisis y diseño se requiere la determinación de una ...

Una formulación numérica sin malla basada en los métodos SPH con ponderación de Galerkin 

Cueto-Felgueroso Landeira, Luis; Colominas, Ignasi; Mosqueira Martínez, Gonzalo; Navarrina, F.; Casteleiro, Manuel (Universitat Politècnica de Catalunya, 2005)
[Resumen] En este artículo se propone una formulación numérica sin malla de tipo Galerkin basada en el método de partículas SPH con aproximación de mínimos cuadrados móviles y su aplicación a problemas de mecánica de fluidos ...

High order finite volume schemes on unstructured grids using Moving Least Squares reconstruction. Application to shallow water dynamics 

Cueto-Felgueroso Landeira, Luis; Colominas, Ignasi; Navarrina, F.; Casteleiro, Manuel (John Wiley and Sons, 2005)
[Abstract] This paper introduces the use of Moving Least Squares (MLS) approximations for the development of high-order finite volume discretizations on unstructured grids. The field variables and their succesive derivatives ...

Why do computer methods for grounding analysis produce anomalous results? 

Navarrina, F.; Colominas, Ignasi; Casteleiro, Manuel (IEEE Power Engineering Society, 2003)
[Abstract] Grounding systems are designed to guarantee personal security, protection of equipments and continuity of power supply. Hence, engineers must compute the equivalent resistance of the system and the potential ...

Topology optimization of structures: a minimum weight approach with stress constraints 

Navarrina, F.; Muíños Pantín, Iago; Colominas, Ignasi; Casteleiro, Manuel (Elsevier, 2004)
Sizing and shape structural optimization problems are normally stated in terms of a minimum weight approach with constraints that limit the maximum allowable stresses and displacements. However, topology structural ...

High Order Shape Design Sensitivity: A Unified Approach 

Navarrina, F.; López Fontán, Santiago; Colominas, Ignasi; Bendito Pérez, Enrique; Casteleiro, Manuel (Elsevier, 2000)
[Abstract] Three basic analytical approaches have been proposed for the calculation of sen- sitivity derivatives in shape optimization problems. The first approach is based on differentiation of the discretized equations ...

On the Galerkin formulation of the smoothed particle hydrodynamics method 

Cueto-Felgueroso Landeira, Luis; Colominas, Ignasi; Mosqueira Martínez, Gonzalo; Navarrina, F.; Casteleiro, Manuel (John Wiley and Sons, 2004)
[Abstract] In this paper, we propose a Galerkin-based smoothed particle hydrodynamics (SPH) formulation with moving least-squares meshless approximation, applied to free surface flows. The Galerkin scheme provides a clear ...

Resolution of the flow in clarifiers by using a stabilized finite element method 

Vellando, Pablo; Puertas, Jerónimo; Colominas, Ignasi (John Wiley and Sons, 2004)
[Abstract] The description of the flow that takes place in clarifiers and other wastewater treatment basins may be a powerful tool to attain an optimum design of these structures, in order to make the most of the wastewater ...

SUPG stabilized finite element resolution of the Navier-Stokes equations: application to water treatment engineering 

Vellando, Pablo; Puertas, Jerónimo; Colominas, Ignasi (Elsevier, 2002)
[Abstract] In this paper an analysis of the viscous incompressible flow has been carried out, from the very definition of the governing equations, up to the resolution of some practical problems, passing through the ...

O sector da construción en Galicia: responsabilidade social empresarial e resultados financeiros 

Vilar Fernández, Juan Manuel; Fe, Jaime; Vasallo Rapela, Alejandro M. (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 ...
