We analyze the effects of spacetime topology and angular velocity rotating frame on dynamics a relativistic vector boson oscillator (VBO). To determine these energy VBO we solve corresponding equation in 2+1 dimensional cosmic string-induced background. obtain an exact spectrum, which depends deficit parameter show that each level cannot be same couples with spin VBO. Furthermore, have obtained...

We show that one may pass from bulk to boundary thermodynamic quantities for rotating AdS black holes in arbitrary dimensions so that if the bulk quantities satisfy the first law of thermodynamics then so do the boundary CFT quantities. This corrects recent claims that boundary CFT quantities satisfying the first law may only be obtained using bulk quantities measured with respect to a certain ...

Shallow water inertio-gravity Poincaré waves in a rotating frame satisfy the Klein–Gordon equation, originally derived for relativistic, spinless quantum particles. Here, we compare these two superficially unrelated phenomena, suggesting reason them sharing same equation. We discuss their energy conservation laws and equivalency between non-relativistic limit of yielding Schrödinger near-inerti...

Ostrovsky’s equation with time- and space-dependent forcing is studied. This model for long waves in a rotating fluid non-constant depth (topography). A classification of Lie point symmetries low-order conservation laws presented. Generalized travelling wave solutions are obtained through symmetry reduction. These exhibit profile that stationary moving reference frame whose speed can be constan...

Astronauts and vestibular patients face analogous challenges to orientation function due to adaptive exogenous (weightlessness-induced) or endogenous (pathology-induced) alterations in the processing of acceleration stimuli. Given some neurovestibular similarities between these challenges, both affected groups may benefit from shared research approaches and adaptation measurement/improvement st...

Since the last Amaldi meeting in 1997 we have learned that the r-modes of rapidly rotating neutron stars are unstable to gravitational radiation reaction in astrophysically realistic conditions. Newborn neutron stars rotating more rapidly than about 100 Hz may spin down to that frequency during up to one year after the supernova that gives them birth, emitting gravitational waves which might be...

In this paper, an analytical solution for computing the plastic & linear plastic stresses and critical angular velocity in a FGM hollow & solid rotating disk is developed. It has been assumed that the modulus of elasticity and yield strength were varying through thickness of the FGM material according to a power law relationship. The Poisson's ratio were considered constant throughout the thick...

The standard inertial Navier–Stokes equations consisting of the conservation for mass, momentum and energy are often used to investigate motion a compressible fluid around an object that is in arbitrary motion. non-inertial form can be accurately capture acceleration effects arise from unsteady source terms equation have been extensively documented. In this paper, Eulerian approach deriving app...
