A unified approach for high order sensitivity analysis
(Computational Mechanics Publications, 2001)
[Abstract] Many engineering problems require solving PDEs by means of numerical methods (type FEM/BEM) which sensivity analysis entails taking derivatives of functions defined through integration. In sizing optimization ...
A meshless numerical approach for the analysis of earthing systems in electrical installations
(Technische Universität München, 1999)
[Abstract] In the last three decades some numerical formulations have been developed for solving potential problems in electrical engineering applications. In the particular case of the grounding analysis area, in recent ...
Meshless methods applied to potential flow problems
(Elsevier, 2001)
[Abstract] In this paper we discuss some of the meshless approaches that have been recently proposed for solving boundary value problems. Several functional approximations and different integration schemes are studied. In ...
Petrov-Galerkin and Galerkin/Least Squares stabilized approaches for advectivediffusive transport problems
(Fundacja Zdrowia Publicznego "Vesalius", 2001)
[Abstract] The Finite Element method with a Galerkin type weighting is a straight-forward weighted residual method that has been sucessfuly used in many engineering applications, specially in Solid Mechanics. However, this ...
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 boundary element numerical approach for earthing grid computation
(Elsevier, 1999)
[Abstract] Analysis and design of substation earthing involves computing the equivalent resistance of grounding systems, as well as distribution of potentials on the earth
surface due to fault currents [1,2]. While very ...
Una formulación numérica sin malla basada en los métodos SPH con ponderación de Galerkin
(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 ...
Una formulación numérica general para el cálculo y diseño de tomas de tierra en grandes instalaciones eléctricas
(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 ...
A 2D numerical model using finite volume method for sediment transport in rivers
(2002)
[Abstract] The study of rivers as ecosystems has many fields of research, like the resolution and comprehension
of flow and sediment transport phenomena. In this communication a 2D numerical model using the
Finite Volume ...
