Use of CPWL approximations in the design of a numerical nonlinear regulator
(Institute of Electrical and Electronics Engineers, 2000-06)
This paper presents the state regulation problem for nonlinear plants with initial conditions in a given bounded region, proposed originally by Kreisselmeier and Birkholzer (1994). An efficient computer implementable ...
Numerical approximation of equations involving minimal/maximal operators by successive solution of obstacle problems
(Elsevier Science, 2018-11)
Let Ω⊂R2 be a polygonal domain, and let Li, i=1,2, be two elliptic operators of the form Liu(x):=−div(Aix∇u(x))+cixu(x)−fix.Motivated by the results in Blanc et al. (2016), we propose a numerical iterative method to compute ...
The numerical solution of the Dirichlet problem for the Helmholtz equation

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 ...
A comparison of approximations to percentiles of the noncentral chi2-distributionA comparison of approximations to percentiles of the noncentral chi2-distribution

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 ...
