The gravity gradient tensor (GGT) is deduced from products of second-order derivatives of the gravitational potential. A new method based on the invariants of the GGT has been proposed in this research to interpret gravity data due to sphere, infinite horizontal cylinder and semi-infinite vertical...

The height variation, due to varying distance from the attracting body, the earth, amounts to 0.3086 mGal m−1 when we are above the earth and to around 0.0848 mGal m−1 (we have seen this gradient already inSection II.B) when we are in the uppermost layer of the earth such as ...
As a direct consequence of the assumption that the beam cross-sections are rigid, in the above equations they are implicitly assumed to remain undeformed when the beam is either lengthened or shortened in the axial direction. Actually, due to the Poisson effect, any axial strain induces a trans...

This study proposes a method for thoroughly interpreting gravitational data stemming from diverse subsurface sources (vertical cylinder, horizontal cylinder, and sphere). This method hinges on applying global particle swarm optimization (GPSO) to the calculated total gradient (TG) of the gravity data....
Fluid motion within the Earth’s liquid outer core leads to internal mass redistribution. This occurs through the advection of density anomalies withi
Due to the space conditions, the free fall of Rubidium and Potassium isotopes will be compared with a maximum accelerational sensitivity of 5·10 − 16 m/s2 corresponding to an accuracy of the test of the Equivalence Principle of 1 part in 1016. Besides the primary scientific goal, ...
The use of classical control strategies such as the Proportional-Integral-Derivative (PID) controller has been a standard solution in industry due to its simplicity, low cost, and easy implementation. However, these controllers, although effective in certain scenarios, present significant limitations whe...
