On the numerical analysis based on successive approximations for power flow problems in AC distribution systems
(Cartagena de Indias, 2020-10)
This paper proposes a new power flow formulation for alternating-current distribution networks for radial and mesh topologies. This formulation corresponds to a successive approximation based on a modification of the ...
Numerical approximation of the Ginzburg-Landau equation with memory effects in the dynamics of phase transitions
(Elsevier B.V., 2008-09-01)
We consider the out-of-equilibrium time evolution of a nonconserved order parameter using the Ginzburg-Landau equation including memory effects. Memory effects are expected to play important role on the nonequilibrium ...

Derivación numérica. Método de diferencias divididas finitas
(2015-06-30)
The numerical derivation is a numerical analysis technique to calculate an approximation to the derivative of a function of a point using the values and properties of it. Basically, in a solution of finite differences, ...
Simple estimation of linear 1+1 D long wave run-up
(Oxford University Press, 2017-05)
An analytical solution is derived concerning the linear run-up for any given initial wave generated over a sloping bathymetry. Due to the simplicity of the linear formulation, complex transformations are unnecessary, hence ...
Alternative method using recursive convolution for electromagnetic transient analysis in balanced overhead transmission lines
(Inst Engineering Technology-iet, 2020-09-01)
This study proposes an alternative method to calculate the transient responses of multi-conductor overhead transmission lines based on ABCD representation, recursive convolutions and numerical method for rational approximation ...
A higher-order ray approximation applied to orographic gravity waves: Gaussian beam approximation
(Amer Meteorological Soc, 2011-01)
Ray techniques are a promising tool for developing orographic gravity wave drag schemes. However, the modeling of the propagation of orographic waves using standard ray theory in realistic background wind conditions usually ...
