Rotational time dilation and angular contraction are discussed in comparison with the time deletion and length contraction of special relativity. The related issues of clock paradox and simultaneity are explored in rotational scenario. The non Euclidian nature of a relativistic rotation is analyzed in both θ t and θ r subspace. It has been shown that the constancy of the speed of light is intri...

Converging psychophysical and electrophysiological evidence suggests that first-order (luminance-defined) complex motion types i.e., radial and rotational motion, are processed by specialized extrastriate motion mechanisms. We ask whether radial and rotational second-order (texture-defined) motion patterns are processed in a similar manner. The motion sensitivity to translating, radiating and r...

Using an example of the galaxy, an attempt is made to explain the flat rotational curves of galaxies by means of the Ampere force. This is the first attempt of fitting the rotational curve without both non-baryonic dark matter and modifications to gravity. Using acceptable models for the galactic magnetic field and plausible physical parameters, we find that the flat rotational curves can be ob...

BACKGROUND Genetically manipulated animals like mice or rabbits play an important role in the exploration of human cardiovascular diseases. It is therefore important to identify animal models that closely mimic physiological and pathological human cardiac function. METHODS In-vivo phase contrast cardiovascular magnetic resonance (CMR) was used to measure regional three-directional left ventri...

A novel multiresolution block motion estimation algorithm for video coding is proposed in this paper. The algorithm estimates motion vectors in a coarse-tone scheme, using the wreath product transform (WPT). All of its sub-band coeecients are used to predict the motion vectors, generating an estimate close to that obtained from the standard exhaustive search method. The multiplication free char...
