Physical Review D, 1992
We describe a new approach to quantum gravity, based on a kind of mean-field approximation. The action, which we choose to be quadratic in curvature and torsion, is made polynomial by replacing the inverse vierbein by its mean value. This action is used to compute the effective action for the vierbein and hence its vacuum expectation value.

In 1917, Einstein postulated that mass should be produced by the interaction with the gravitational field and, later on, introduced the cosmological constant for a model of cosmological finite space. This was then followed by the Brans Dicke's (1961) scalar-tensor theory and the idea that the mass of the elementary particles is produced by their ...

Ninian Field Concrete Gravity Platform
SPE European Petroleum Conference, 1978Abstract The Ninian Central Platform was built at Loch Kishorn by Howard-Doris for Chevron (UK) Ltd. The paper discusses the design process together with the construction methods. Special emphasis is given to the maximum flexibility of the construction stages to optimise the overall construction ...

Physical Review D, 1986
We propose a Yang-Mills field theory of gravity based on a unitary phase gauge invariance of the Lagrangian where the gauge transformations are those of the SU(2)\ifmmode\times\else\texttimes\fi{}U(1) symmetry of the two spinors. In a classical limit this microscopic theory results in Einstein's metrical theory of gravity, where we restrict ourselves ...

A concept for an operable software system for the processing of a high-accuracy, high-resolution spherical harmonic model of the Earth’s gravity field from GOCE observables (satellite gravity gradiometry (SGG), satellite-to-satellite tracking in high-low mode (hl-SST)) is presented. The software architecture and the data flow are briefly described, and

Airborne Gravity Field Determination
2010Airborne measurement of gravity has long been a goal for geodesy and geophysics, both to serve geodetic needs (such as geoid determination) and in order to provide efficient and economic mapping of gravity anomalies for geophysical exploration. Although airborne gravimetry has been attempted since the 1960s (LaCoste 1967), it is only in the 1990s, with
