Research ArticleOpen accessIn the abstractESTIMATIONS OF TOTAL MASS AND ENERGY OF THE OBSERVABLE UNIVERSEDimitar ValevThe recent astronomical observations indicate that the expanding universe is homogeneous, isotropic and asymptotically flat. The Euclidean geometry of the universe enables to determine the total gravitational and kinetic energy of the universe by Newtonian gravity in a flat space. By means of dimensional analysis, we have found the mass of the observable universe close to the Hoyle-Carvalho formula M∼c3/(GH). … …Physics International, Vol. 5, Issue 1 · 21 Mar 2014 · 17,715 accessesView PDFCite
Research ArticleOpen accessIn the abstractMODELING THE UNIVERSE AS A QUANTUM WELLMichael Harney, Julie SealBy modeling the Universe as a quantum well for standing waves and solving Schrodinger’s equation for a particle trapped in this well, the solutions for the allowable rest-energies of all particles in the Universe are obtained, from the mass of the photon up to the mass of the Universe. The quantum numbers that predict the allowable rest-energies of all particles … …Physics International, Vol. 5, Issue 1 · 19 Mar 2014 · 8,245 accessesView PDFCite
Research ArticleOpen accessIn the abstractNon-Singular Thermodynamic GravityPharis E. WilliamsNewton formed his laws of motion, but still had to assume a law of gravity in order to determine the motions of bodies interacting through gravitational forces. Newton gave a prescription of how to find the dynamics produced by gravity. Einstein sought to determine the motions of gravity without using a force. Rather, he sought a system of equations by … …Space Science International, Vol. 1, Issue 2 · 23 Dec 2013 · 7,657 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE THEORY OF METARELATIVITY: BEYOND ALBERT EINSTEIN’S RELATIVITYAbdo Abou JaoudeThe theory of metarelativity is a system of equations written to take into consideration additional effects in the universe and about the matter inside it. The study begins with Albert Einstein’s theory of special relativity and it develops a system of equations which lead us to further explanations and to a new physics paradigm. Like special relativity which was created … …Physics International, Vol. 4, Issue 2 · 4 Sep 2013 · 7,743 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Bounded Expanding Carmelian White Hole Universe Without Dark MatterJohn Gideon HartnettThe solution of Einstein’s field equations in Cosmological General Relativity (CGR), where the Galaxy is at or cosmologically near the center of a finite yet bounded spherically symmetrical isotropic gravitational field, is identical with the unbounded solution. I show that this leads to the conclusion that the Universe may be viewed as a finite expanding white hole. The fact that … …Physics International, Vol. 3, Issue 2 · 7 May 2013 · 6,941 accessesView PDFCite
Research ArticleOpen accessIn the abstractManaging Process Hazards in Lab-Scale Pilot Plant for Safe OperationHanida Abdul Aziz, Azmi Mohd Shariff, Mohd Rafizie RoslanIn spite of the OSHA Laboratory and Hazards Communication Standards, incidents which result in injuries and property loss continue to occur in the research and teaching locations. Application of Process Hazard Analysis (PHA) of OSHA Process Safety Management (PSM) to laboratory pilot plant operations has the potential to further reduce risk associated with this location. However, a major challenge is … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 26 May 2012 · 9,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractReal Time Implementation of NARMA-L2 Control of a Single Link ManipulatorS.S. Mokri, H. Husain, W. Martono, A. ShafieNonlinearities and parametric uncertainties are unavoidable problems faced in controlling robot manipulator. A single link manipulator driven by a permanent magnet brushed dc motor is a nonlinear dynamics due to effects of gravitational force, mass of the payload, posture of the manipulator and viscous friction coefficient. Furthermore, uncertainties arise because of changes of the rotor resistance with temperature and random … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,762 accessesView PDFCite

In a special expression of electrostatics, we describe Informative Intensity, Informative Response Intensity and Informative Flux in terms of electric field intensity, electric field force and electric field flux respectively. In a special expression of quantum mechanics, we originally propose a concept of Probability … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 6,873 accessesView PDFCite

From the solution it has been shown that the domain walls have repulsive gravitational fields. …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 6,237 accessesView PDFCite
Research ArticleOpen accessIn the abstractLarge Eddy Simulation of an Ammonia JetM. Salinas-Vazquez, A. Espinosa, E. Barrios, W. VicenteA compressible jet flow of ammonia was studied through a series of Large Eddy Simulations. Simulations were focused in the zone where the inertial effects are much bigger than the gravitational ones. The ammonia jet is discharged into an air medium and the gases are treated as a two non-reactive ideal gas mixture. Different simulations were performed, going from the … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,743 accessesView PDFCite
