The cosmography known as the Padé polynomials has been widely used in the reconstruction of luminosity distance, and the orders of Padé polynomials influence the reconstructed result derived from Padé ...

Abstract: This article proposes an expression for the calculation of the ground-return impedance of underground cables based on a Padé approximation of Sunde's integral equation. The accuracy of the ...

Abstract: This letter presents a higher order finite-difference (FD) and Padé approximations method for the three-dimensional (3-D) parabolic equation (PE) to predict radio-wave propagation. This ...

@sergio-dorado reported an issue over email that I will add below. When attempting to linearize certain blocks (e.g. the delay=Modelica.Blocks.Nonlinear.FixedDelay model), any Modelica tool should ...

In some models the accuracy of the sigmoid and tanh functions can be reduced without a loss of accuracy in the training process. Switching to an approximation can reduce training times significantly ...

The luminosity distance in the standard cosmology as given by ΛCDM and, consequently, the distance modulus for supernovae can be defined by the Padé approximant. A comparison with a known analytical ...

Partial differential equations describing dynamics of diffusional processes, when coupled with other differential equations, are difficult to simulate and analyze. To overcome such difficulties of ...
