Influences of the load centre of gravity on heavy vehicle acceleration
(Inderscience Enterprises Ltd, 2001-01-01)
The aim of this paper is to analyse the influence of the load centre of gravity on heavy vehicle acceleration. This analysis is done through a method in which a vehicle centre of gravity map is used. A model for the driving ...
Study of salt structures from gravity and seismic data in Santos Basin, Brazil
(Inst Geophysics Unam, 2016-07-01)
Seismic is one of the main methods used for the identification of structures and stratigraphic studies in sedimentary basins. In the Santos Basin, numerous 2D and 3D seismic surveys are being conducted in order to get a ...
Kerr geometry in f(T) gravity
(Springer, 2015-02)
Null tetrads are shown to be a valuable tool in teleparallel theories of modified gravity. We use them to prove that Kerr geometry remains a solution for a wide family of theories of gravity.
Spherically symmetric static spacetimes in vacuum f(T) gravity
(American Physical Society, 2011-10)
We show that Schwarzschild geometry remains as a vacuum solution for those four-dimensional f ( T ) gravitational theories behaving as ultraviolet deformations of general relativity. In the gentler context of three-dimensional ...
Differential geometry, Palatini gravity and reduction
(American Institute Of Physics, 2014-01)
The present article deals with a formulation of the so called (vacuum) Palatini gravity as a general variational principle. In order to accomplish this goal, some geometrical tools related to the geometry of the bundle of ...
A novel teleparallel dark energy model
(2016-02-01)
Although equivalent to general relativity, teleparallel gravity (TG) is conceptually speaking a completely different theory. In this theory, the gravitational field is described by torsion, not by curvature. By working in ...
Basement structures over Rio Grande Rise from gravity inversion
(2017-04-01)
The basement depth in the Rio Grande Rise (RGR), South Atlantic, is estimated from combining gravity data obtained from satellite altimetry, marine surveys, bathymetry, sediment thickness and crustal thickness information. ...
Gravity anomalies over extinct spreading centres: A new evidence of an aborted ridge in the South Atlantic Ocean
(2019-01-01)
An aborted ridge has been suggested in the Vema region, South Atlantic Ocean, and we investigate it in terms of residual gravity anomalies and half spreading rate. Gravity signature over extinct spreading centres displays ...
Variação da massa específica da madeira de Eucalyptus grandis aos 8 anos de idade em função de diferentes níveis de produtividade
(1998-12-01)
It were analyzed Eucalyptus grandis trees of 8 years old in the forest group of Duraflora S/A, with different annual increments based on volume, to the related studies of specific gravity values based on productivity ...
Structure of neutron stars in R-squared gravity
(Springer, 2013-03)
The effects implied for the structure of compact objects by the modification of General Relativity produced by the generalization of the Lagrangian density to the form R plus alpha R-squared, where R is the Ricci curvature ...
