Conditional symmetries and the canonical quantization of constrained minisuperspace actions: The Schwarzschild case
(2013)A conditional symmetry is defined, in the phase space of a quadratic in velocities constrained action, as a simultaneous. conformal symmetry of the supermetric and the superpotential. Iris proven that such a symmetry ... 
Effect of channel width on the primary instability of inclined film flow
(2010)A procedure is developed to detect the onset of interfacial instability in inclined film flows (with estimated accuracy better than 5%) and is used to show that the finite width of experimental channels stabilizes the ... 
Energy Distribution of a Regular Black Hole Solution in EinsteinNonlinear Electrodynamics
(2015)A study about the energy momentum of a new fourdimensional spherically symmetric, static and charged, regular black hole solution developed in the context of general relativity coupled to nonlinear electrodynamics is ... 
Energy distribution of the EinsteinKleinGordon system for a static spherically symmetric spacetime in (2+1) dimensions
(2006)We use Moller's energymomentum complex in order to explicitly compute the energy and momentum density distributions for an exact solution of Einstein's field equations with a negative cosmological constant, minimally ... 
Falling film flow along steep twodimensional topography: The effect of inertia
(2008)Steady film flow along a vertical wall with isolated step changes is studied numerically for Reynolds numbers Re similar to O(10(3)10(2)) and capillary numbers Ca similar to O(10(2)10(1)). The lengthscale of free surface ... 
Minisuperspace canonical quantization of the ReissnerNordstrom black hole via conditional symmetries
(2014)We use the conditional symmetry approach to study the r evolution of a minisuperspace spherically symmetric model both at the classical and the quantum level. After integration of the coordinates t, theta and phi in the ... 
A new method for the characterization of electrically conducting liquid bridges
(2000)An electrical conductance technique is employed in investigating the behavior of constant volume liquid bridges when their length is altered. The liquid bridges are edgepinned between two vertical, identical rods with a ...
