Energy of gravitational radiation in plane-symmetric space-times [PDF]
, 2008 Gravitational radiation in plane-symmetric space-times can be encoded in a complex potential, satisfying a non-linear wave equation. An effective energy tensor for the radiation is given, taking a scalar-field form in terms of the potential, entering the

Improved equation to describe the induction motor currents during nearby three‐phase short‐circuits
IET Electric Power Applications, 2023 This article shows an improved equation to describe the induction motor currents during a three‐phase short‐circuit near to motor terminals. The proposed equation considers three details which are not in the equation shown in the IEEE Std.

Radiative Transfer Limits of Two-Frequency Wigner Distribution for Random Parabolic Waves [PDF]
, 2006 The present note establishes the self-averaging, radiative transfer limit for the two-frequency Wigner distribution for classical waves in random media. Depending on the ratio of the wavelength to the correlation length the limiting equation is either a ...

Nonlinear Schrödinger equation and frequency saturation [PDF]
Analysis & PDE, 2012 We propose an approach that permits to avoid instability phenomena for the nonlinear Schrodinger equations. We show that by approximating the solution in a suitable way, relying on a frequency cut-off, global well-posedness is obtained in any Sobolev space with nonnegative regularity.
