Self-consistent solutions for low-frequency gravitational background radiation [PDF]

open access: yes, 1997
We study in a Brill-Hartle type of approximation the back-reaction of a superposition of linear gravitational waves in an Einstein-de Sitter background up to the second order in the small wave amplitudes $h_{ik}$.

On Extending the Automatic Test Markup Language (ATML) for Machine Learning [PDF]

open access: yesarXiv
This paper addresses the urgent need for messaging standards in the operational test and evaluation (T&E) of machine learning (ML) applications, particularly in edge ML applications embedded in systems like robots, satellites, and unmanned vehicles.

On the numbers $e^e, e^{e^2}$ and $e^{\pi^2}$. [PDF]

open access: yes, 1998
We give two measures of simultaneous approximation by algebraic numbers, the first one for the triple $( e, e^e, e^{e^2})$ and the second one for $(\pi, e, e^{\pi^2})$. We deduce from these measures two transcendence results which had been proved in the early 70's by W. D. Brownawell and the author.

A model for gravity-wave spectra observed by Doppler sounding systems [PDF]

open access: yes, 1986
A model for Mesosphere - Stratosphere - Troposphere (MST) radar spectra is developed following the formalism presented by Pinkel (1981). Expressions for the one-dimensional spectra of radial velocity versus frequency and versus radial wave number are ...
