Improved geometric parameterisation techniques for continuation power flow
(Inst Engineering Technology-iet, 2010-12-01)
This study presents efficient geometric parameterisation techniques for the continuation power flow. The Jacobian matrix singularity is eliminated by the addition of the line equations which pass through the points in the ...
An Ultraweak Formulation Of The Kirchhoff-Love Plate Bending Model And Dpg Approximation
(2019)
We develop and analyze an ultraweak variational formulation for a variant of the Kirchhoff-Love plate bending model. Based on this formulation, we introduce a discretization of the discontinuous Petrov-Galerkin type with ...
Alternative parameterization for assessing branch outages by a continuation method
(2004-12-01)
This paper proposes and tests new parameters, namely the voltage magnitudes, phase angles and the total power losses, for evaluating the effects of branch outages. The approach can be used as a verification tool after a ...
Isogeometric boundary element methods for three dimensional static fracture and fatigue crack growth
(Elsevier, 2017)
We present a novel numerical method to simulate crack growth in 3D, directly from the Computer-Aided Design (CAD)
geometry of the component, without any mesh generation. The method is an isogeometric boundary element ...
Surface diffusion of graphs: Variational formulation, error analysis, and simulation
(Society for Industrial and Applied Mathematics, 2004-12)
Surface diffusion is a (fourth-order highly nonlinear) geometric driven motion of a surface with normal velocity proportional to the surface Laplacian of mean curvature. We present a novel variational formulation for graphs ...

EVALUATION OF NUMERICAL METHODS APPLIED IN THE ANALYSIS OF THE TRANSIENT FLOW OF PIPELINE SYSTEMS
(Amer Soc Mechanical Engineers, 2013-01-01)
Brazilian subsea exploration is increasing specially after the post salt petroleum field discovery. Several challenges have been imposed for the production of those fields. In this scenery, the transport of oil and gas ...
