Cosmic acceleration is explained quantitatively, as an apparent effect due to gravitational energy differences that arise in the decoupling of bound systems from the global expansion of the universe. “Dark energy” is a misidentification of those aspects of gravitational energy which by virtue of the equivalence principle cannot be localised, namely gradients in the energy due to the expansion o...

The acceleration of charged particles in the presence of a magnetic field and gravitational waves is under consideration. It is shown that the weak gravitational waves can cause the acceleration of low energy particles under appropriate conditions. Such conditions may be satisfied close to the source of the gravitational waves if the magnetized plasma is in a turbulent state.

A novel method for measuring human gait posture using wearable sensor units is proposed. The sensor units consist of a tri-axial acceleration sensor and three gyro sensors aligned on three axes. The acceleration and angular velocity during walking were measured with seven sensor units worn on the abdomen and the lower limb segments (both thighs, shanks and feet). The three-dimensional positions...

Discussion of different types of osculating orbital elements for motion of real dust particle under the action of electromagnetic radiation in the central gravitational field is presented. It is shown that physically correct access is based on gravitational acceleration as the only radial acceleration – " radiation pressure " is not included in the radial acceleration.

Gravitational Thomas Precession ( GTP ) is the name given to Thomas Precession when the acceleration is caused by a gravitational force field. The contribution of the GTP to the the anomalous perihelion advance of the orbit of Mercury is here estimated at ̇̃ ωGTP = 21 · 49 [ 1 + ( ~ L · ~ S ) L ] arcsec/century ,where ~ L and ~ S respectively represents the orbital angular momentum and the spin a...
