We investigated the effect of visual and vestibular body-tilt cues on the subjective visual vertical (SVV) in six human observers at roll tilts of 0, 60, and 120 degrees . Subjects adjusted a small luminous test line parallel to the perceived direction of gravity, in the presence of a large peripheral visual frame line. These settings, referred to as the frame SVV, were compared with the SVV in...

We give an elementary derivation of the Montgomery phase formula for the motion of an Euler top, using only basic facts about the Euler equation and parallel transport on the 2-sphere (whose holonomy is seen to be responsible for the geometric phase). We also give an approximate geometric interpretation of the geometric phase for motions starting close to an unstable equilibrium point. Introduc...

Abstract A process specific to the dynamics of heavy impurities in turbulent tokamak plasmas is found and analyzed. We show that parallel stochastic acceleration strongly coupled perpendicular transport generates a radial pinch velocity. The interaction produced with hidden drifts, quasi-coherent component motion consists pair average velocities opposite directions. breaks this symmetry yields ...

Simulation-based experiment of complex systems is a time consuming-job. Parallel and distributed simulation is one of the methods to reduce the simulation time. To simulate and analyze the system with this method, it is required to design a suitable experimental frame. Therefore, this paper proposes a MapReduce based experimental frame for the parallel and distributed simulation. Because Hadoop...
