Gravitational Thomas Precession ( GTP ) is the name given to Thomas Precession when the acceleration is caused by a gravitational force field. The GTP gives a negative contribution of 7 · 163 arcsec/century for the anomalous perihelion advance of Mercury’s orbit.This effect seems to be of some concern for the General Relativity. PACS: 04.80Cc ; 96.30Dz

We consider the generalized Störmer Problem that includes the electromagnetic and gravitational forces on a charged dust grain near a planet. For dust grains a typical charge to mass ratio is such that neither force can be neglected. Including the gravitational force gives rise to stable circular orbits that encircle that plane entirely above/below the equatorial plane. The effects of the diffe...

We review new constraints on the Yukawa-type corrections to Newtonian gravity obtained recently from gravitational experiments and from the measurements of the Casimir force. Special attention is paid to the constraints following from the most precise dynamic determination of the Casimir pressure between the two parallel plates by means of a micromechanical torsional oscillator. The possibility...

This paper describes a novel approach, called Force Field Simulation, to multi robot mapping that works under the constraints given in autonomous search and rescue robotics. Extremely poor prealignment, lack of landmarks, and minimal overlap between scans are the main challenges. The presented algorithm solves the alignment problem of such laser scans utilizing a gradient descent approach motiv...

We present a new algorithm to rapidly compute the two-point (2PCF), three-point (3PCF) and n-point (n-PCF) correlation functions in roughly O(N) time for N particles, instead of O(Nn) as required by brute force approaches. This technique exploits node-to-node correlations of a recursive bisectional binary tree. A balanced tree construction minimizes the depth of the tree and the worst case erro...

Dust growth by agglomeration due to a new mechanism of dust attraction is shown to compete in space plasmas with the standard accretion mechanism by neutral particles. We demonstrate that dust growth by accretion of neutrals and plasma particles is aided by a pressure force due to a shadowing effect first proposed (Bingham & Tsytovich 2001) to explain rapid growth of dust in laboratory discharg...

Gravity has been constant throughout the history of Earth. This simple fact masks the complexity of gravity as an evolutionary force. Gravity is a vector, i.e. a force that has magnitude and direction at each point in space. Gravitational loading is directional toward the center of the Earth. Gravitational loading acts on all masses at the Earth’s surface and defines the weight of each object. ...

Traditional Newtonian mechanics treats gravity as one of the forces contributing to the acceleration of a body in motion. Newtonian natural motion is defined relative to an abstract inertial space where gravity is non-existent and free body velocity motion remains constant unless modified by applied force. With this interpretation, gravitational force is an embedded characteristic whose effect ...
