    Abstract: We report on a simple study involving a single non-Brownian sphere settling under the influence of gravity in a quiescent viscous fluid housed in a finite square duct. Spheres are shown to achieve terminal velocity in a fraction of the time predicted by infinite fluid dynamics. Terminal velocities agree well with right cylinder equations for sphere... Show More

    Abstract: It is well known that the equations of conservation laws for energy, linear momentum, angular momentum, and mass are the equations of mechanics and physics of continuous media that describe material systems such as the thermodynamical, gas-dynamical and cosmological systems. And the field-theory equations, which are used for description of physical... Show More

    Abstract: Using the Adomian decomposition method (ADM), we present in this paper a numerical approximation of the solution of the nonlinear KDV equation. The principal task concerns essentially the computation of the Adomian polynomials for this type of equation and thereafter determining a significant criterion to ensure the conditions for convergence of th...

    Abstract: Pulse sources of electromagnetic radiation based on a low-inductive extended z-discharge are studded experi-mentally and numerically. Z-discharge is initiated by a high-voltage pulse generator through a long transmission line. It is shown that using a sliding avalanche discharge traveling wave, one can provide electrical breakdown of long discharge... Show More

    Abstract: First, by using cylindrically symmetric model, the quantum state for cyclic Universe is studied. It is shown that the ground state for oscillating cylindrical Universe is a maximally entangled with two-mode squeezed states on expanding and contracting Hilbert spaces of Universe. Next, the production cross section for each Universe state is obtained... Show More

    Abstract: The topology change in quantum gravity is modeled by a Ricci flow. In this approach we consider the Ricci flow as a statistical system. The metric in the Ricci flow enumerated by a parameter is a microscopical statistical state. The probability of every microscopical state is determined by this parameter. The Ricci flow starting from a static wor... Show More

    Abstract: A simple operating principle (similar to a combination of a pottery wheel and a catapult or, simply, the weapon used by David to slay Goliath) coupled with the success of some moderate engineering challenges may allow for the transmission of a carrier wave from Earth to Mars in less than one second!This paper also directly addresses the controversy...

    Abstract: In this paper, a novel all-optical NOR logic gate based on two dimension (2-D) photonic crystals (PC) is designed and simulated by a cascade of two all-optical switches. The new all-optical switch is composed of a nonlinear photonic crystal ring resonator (PCRR) and T-type waveguide. The PC structure has a square lattice of silicon rod with refract... Show More

    Abstract: We summarize first the highlights of the paper by Volovik, 2006 as to Vacuum energy and afterwards state that the non applicabillty of “Fjortoft theorem” for defining necessary conditions for instability solves certain problems raised by Volovik. The Myths and Realitites of Vacuum energies as stated by Volovik in particular state that there can be ... Show More

    Abstract: The purpose of the theory of concentration is to demonstrate how the photons of energy were concentrated into spherical materials because of the gravity that stabilizes them. In fact, it is the theory of concentration that elucidates perfectly the transition from infinitely small to infinitely great. It should be noted that its concepts are essenti... Show More
