Gravitation as Anholonomy [PDF]

open access: yesGeneral Relativity and Gravitation, 2003
A gravitational field can be seen as the anholonomy of the tetrad fields. This is more explicit in the teleparallel approach, in which the gravitational field-strength is the torsion of the ensuing Weitzenboeck connection. In a tetrad frame, that torsion is just the anholonomy of that frame.

The cause of axial rotation of the scoliotic spine [PDF]

open access: yes, 1991
To explain the cause of axial rotation in a scoliotic vertebral column, the influence of the gravitation force on a spine with a C-scoliosis has been investigated by means of a mechanical model. In this model the gravitation force takes hold of the three-

Gravitational Lensing of Continuous Gravitational Waves [PDF]

open access: yesUniverse, 2021
Continuous gravitational waves are analogous to monochromatic light and could therefore be used to detect wave effects such as interference or diffraction. This would be possible with strongly lensed gravitational waves. This article reviews and summarises the theory of gravitational lensing in the context of gravitational waves in two different ...

On the invisibility and impact of Robert Hooke’s theory of gravitation

open access: yesOpen Philosophy, 2020
Robert Hooke’s theory of gravitation is a promising case study for probing the fruitfulness of Menachem Fisch’s insistence on the centrality of trading zone mediators for rational change in the history of science and mathematics.

Gravitation-based personalized recommendation algorithm

open access: yes工程科学学报, 2015
A recommendation algorithm is proposed by introducing the universal law of gravitation into a recommendation system. This new algorithm is named as the gravitation-based personalized recommendation (GBPR) algorithm.

Some applications of the Shapiro time delay [PDF]

open access: yesSerbian Astronomical Journal, 2023
Listening to echoes has long been a way to estimate distances, a technique whose backbone is the time delay. The gravitational field also creates a time delay, called Shapiro time delay, that helps us extract some information from the field and ...

Probing Yukawian gravitational potential by numerical simulations. I. Changing N-body codes [PDF]

open access: yes, 2009
In the weak field limit general relativity reduces, as is well known, to the Newtonian gravitation. Alternative theories of gravity, however, do not necessarily reduce to Newtonian gravitation; some of them, for example, reduce to Yukawa-like potentials ...

Gravitational waves at their own gravitational speed [PDF]

open access: yesInternational Journal of Modern Physics D, 2018
Gravitational waves propagate at the speed of light in general relativity, because of their special relativistic basis. However, light propagation is linked to the electromagnetic phenomena, with the permittivity and permeability constants as the determining factors.
