[EN] Here, some aspects in the interpretation of the solutions
of a PEC infinite circular cylinder with the Theory of Characteristic
Modes are presented. First, natural resonances and characteristic mode
resonances (CMRs) ...
In this paper, we present a conceptual-numerical model that can be deduced from a calibrated finite difference groundwater-flow model, which provides a parsimonious approach to simulate and analyze hydraulic heads and ...

[EN] In this article, a parallel structured divide-and-conquer (PSDC) eigensolver is proposed for symmetric tridiagonal matrices based on ScaLAPACK and a parallel structured matrix multiplication algorithm, called PSMMA. ...
García Ariza, Alexis Paolo; Rubio Arjona, Lorenzo(Institute of Electrical and Electronics Engineers (IEEE), 2011-10)
Under realistic propagation conditions in multiple-input-multiple-output (MIMO) wireless channels, some experimental (measured) full-spatial-correlation (FSC) MIMO channel matrices may not be positive definite, especially ...
[EN] When linearity can be assumed (linear response of heads to stresses), stream-aquifer flow exchange can be simulated as the drainage of a number of independent linear reservoirs. This conceptual model, which can be ...

[EN] Electro-optic phase modulators driven by a single radio-frequency tone ¿ can be described at the quantum level as scattering devices where input single-mode radiation undergoes energy changes in multiples of h¿. In ...
Robles-Ruiz, Ruben; Sala, Antonio; Bernal Reza, Miguel Ángel; Gonzalez-German, Ivan Temoatzin(Institute of Electrical and Electronics Engineers, 2017-08)
[EN] Given a nonlinear system, the sector-nonlinearity methodology provides a systematic way of transforming it in an equivalent Takagi-Sugeno (T-S) model. However, such transformation is not unique: conservatism of ...
