Ocular Effects of Gravity Inversion
JAMA: The Journal of the American Medical Association, 1985To the Editor.— Friberg and Weinreb 1 recently reported the occurrence of increased intraocular pressure with the head-down position, and suggested that patients with certain conditions, including glaucoma, should refrain from inversion altogether. Report of a Case.— We recently saw a 68-year-old athletic physician in excellent health who was first ...

Generalized compact gravity inversion
Geophysics, 1994Abstract Extending the compact gravity inversion technique by incorporating a priori information about the maximum compactness of the anomalous sources along several axes provides versatility. Thus, the method may also incorporate information about limits in the axes lengths or greater concentration of mass along one or more ...

Convergence of iterative gravity inversion
Geophysics, 1986Abstract Oldenburg (1974) presented an iterative inversion procedure based on (a rearrangement of) Parker's (1973) formula for rapid calculation of the gravity anomaly caused by an uneven layer; the algorithm proved effective in practice (Sprenke and Kanasewich, 1982). Nevertheless, Oldenburg stated that straightforward application of

On Gravity Inversion by No-Topography and Rigorous Isostatic Gravity Anomalies
Pure and Applied Geophysics, 2015We discuss some theoretical aspects and practical consequences of using traditional versus “new”/rigorous formulations of the Bouguer and isostatic gravity anomalies/disturbances. In principle, the differences between these two concepts are in the definition of the so-called secondary indirect topographic effect (SITE) on the gravity data.

Techniques in Doppler gravity inversion
Journal of Geophysical Research, 1974The types of Doppler gravity data available for local as opposed to planetwide geophysical modeling are reviewed. Those gravity fields that are determined dynamically in orbit determination programs yield a smoothed representation of the local gravity field that may be used for quantitative modeling.

Inversion Reconstruction of Gravity Potential Based on Gravity Gradients
Mathematical Geosciences, 2008A new method was developed for the inversion reconstruction of gravity potential. This method offers the possibility to determine the potential function and all of its important derivatives using the common inversion of gravity gradients and the first derivatives of potential. Gravity gradients can be originated from Torsion balance measurements, while

The inversion process for gravity interpretation has to treat the intrinsic ambiguities of the gravimetric data; for this reason, the possible investigated models need to be constrained in order to recover the uniqueness of the inversion process. In this work, a novel approach to gravimetric inversion is presented. Geometric information on the existing

Lithological Constrained Gravity Inversion. A Bayesian Approach
81st EAGE Conference and Exhibition 2019, 2019A new method for the gravity inversion is presented. It is based on a Bayesian approach and it allows to preserve sharp boundary between different lithologies.

3D STOCHASTIC GRAVITY INVERSION ON UNSTRUCTURED MESHES
Symposium on the Application of Geophysics to Engineering and Environmental Problems 2014, 2014The stochastic gravity inversion on unstructured meshes is presented. The unstructured meshes are used because they provide the flexibility required to closely approximate complicated geological structures. Sharp topographic relief and geological bodies of complex shapes are usually more accurately described by unstructured meshes rather than with ...
