High order finite volume schemes on unstructured grids using Moving Least Squares reconstruction. Application to shallow water dynamics
(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 ...
A general numerical model for grounding analysis in layered soils
(Elsevier, 2002)
[Abstract] Safety of persons, protection and equipment and continuity of power supply are the main objectives of the grounding system of a large electrical installation. For its accurate design, it is essential to determine ...
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 ...

A generalized statement for advective-diffusive phenomena. Finite element model and applications
(John Wiley and Sons, 2000)
[Abstract] Solving convective-diffusive transport problems is a frequent task in engineering, especially in
convection dominated situations. Moreover, the standard statement for the transport problem leads to
the result ...
Boundary element formulation for the analysis of transferred potentials in electrical installations
(Elsevier, 2004)

(IEEE Power Engineering Society, 2003)
[Abstract] In this work we present a numerical formulation for the analysis of a common problem in electrical engineering
practice, that is, the existence of transferred earth potentials
in a grounding installation [1]. ...
Computer analysis of earthing systems in horizontally or vertically layered soils
(Elsevier, 2001)
[Abstract] The main objectives of grounding systems are to guarantee the personal safety, the equipment protection and the continuity of the power supply. To attain these goals, the potential distribution on the earth ...
A boundary element formulation for the substation grounding design
(Elsevier, 1999)
[Abstract] A Boundary Element approach for the numerical computation of substation grounding systems is presented. In this general formulation, several widespread intuitive methods (such as Average Potential
Method) can ...
