Gravity reference at the Argentinean–German Geodetic Observatory (AGGO) by co-location of superconducting and absolute gravity measurements
(Springer, 2020-11-25)
The Argentinean–German Geodetic Observatory (AGGO) is a fundamental geodetic observatory located close to the city of La Plata, Argentina. Two high-precision gravity meters are installed at AGGO: the superconducting ...
Estimation of optimal gravity wave parameters for climate models using data assimilation
(John Wiley & Sons Ltd, 2011-09)
There is a current need to constrain the parameters of gravity wave drag schemes in climate models using observational information instead of tuning them subjectively. In this work, an inverse technique is developed using ...
Lyra scalar-tensor theory: A scalar-tensor theory of gravity on Lyra manifold
(2021-06-15)
We present a scalar-tensor theory of gravity on a torsion-free and metric compatible Lyra manifold. This is obtained by generalizing the concept of physical reference frame by considering a scale function defined over the ...
Regional Model to Estimate Vertical Deformations Due to Loading Seasonal Changes
(Springer Verlag Berlín, 2016-01)
Surface mass transfer produces changes in the terrestrial geometric reference frame that are clearly detectable by GNSS techniques. These deformations are mainly observed in the vertical coordinate component and show ...
Cosmological wormholes in f(R) theories of gravity
(2016)
Motivated by recent proposals of possible wormhole existence in galactic halos, we analyze the cosmological evolution of wormhole solutions in modified f(R) gravity. We construct a dynamical wormhole that asymptotically ...
Estimativa da profundidade do embasamento na bacia potiguar usando inversão gravimétrica
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 2012-06-20)
The gravity inversion method is a mathematic process that can be used to
estimate the basement relief of a sedimentary basin. However, the inverse problem
in potential-field methods has neither a unique nor a stable solution, ...
