Semilinear elliptic problems near resonance with a nonprincipal eigenvalue
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
We consider the Dirichlet problem for the equation -Delta u = lambda u +/- (x, u) + h(x) in a bounded domain, where f has a sublinear growth and h is an element of L-2. We find suitable conditions on f and It in order to ...
New contributions to the determination of resonance frequencies of rectangular microstrip antennas by neural networks
(2008-12-01)
This paper uses artificial neural networks (ANN) to compute the resonance frequencies of rectangular microstrip antennas (MSA), used in mobile communications. Perceptron Multi-layers (PML) networks were used, with the ...

Shifted equivalent sources and FFT acceleration for periodic scattering problems, including Wood anomalies
(Academic Press Inc Elsevier Science, 2019-02)
This paper introduces a fast algorithm, applicable throughout the electromagnetic spectrum, for the numerical solution of problems of scattering by periodic surfaces in twodimensional space. The proposed algorithm remains ...
Caustics of the restricted three-body problem
(Edp Sciences S A, 1998-03-01)
Trajectories of the planar, circular, restricted three-body problem are given in the configuration space through the caustics associated to the invariant tori of quasi-periodic orbits. It is shown that the caustics of ...
