Research ArticleOpen accessIn the abstractA First-Class Ticket to the Planet Mars, PleaseRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.The paper presents some aspects related to the current stage in the aerospace industry, referring to the current possibilities of moving in space. The main problem that has kept mankind for so many millennia has been the less speed of movement, but also the difficult exit into outer space. For a ship to be able to defeat gravitational forces and … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 4 · 1 Dec 2017 · 7,008 accessesView PDFCite
Research ArticleOpen accessIn the abstractDerivation of Potentially Important Masses for Physics and Astrophysics by Dimensional AnalysisDimitar ValevThe Hubble constant has been added in addition to the three fundamental constants (speed of light, gravitational constant and Planck constant) used by Max Planck, for derivation of the Planck mass by dimensional analysis. As a result, a general solution is found for the mass dimension expression m = γp m0, where m0 ≡ mp is the Planck mass, γ … …Physics International, Vol. 8, Issue 1 · 25 Oct 2017 · 9,141 accessesView PDFCite
Research ArticleOpen accessIn the abstractAirlanderRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.Man always dreamed of flying. The important thing is not that it succeeded but that it has evolved permanently, improving its flight. The main problem in aviation was also the safety of the flight. How to keeps in the air, even when serious problems arise. Generally, the porting was made with engines and wings. But such support can’t be very … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 2 · 5 Jul 2017 · 7,930 accessesView PDFCite
Research ArticleOpen accessIn the abstractMaximally Distant Codes Allocation Using Chemical Reaction Optimization and Ant Colony Optimization AlgorithmsTaisir Eldos, Waleed Nazih, Aws KananError correcting codes, also known as error controlling codes, are set of codes with redundancy that allows detecting errors. This is quite useful in transmitting data over a noisy channel or when retrieving data from a storage with possible physical defects. The idea is to use a set of code words that are maximally distant from each other, hence reducing … …Journal of Computer Science, Vol. 11, Issue 8 · 5 Nov 2015 · 7,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimations of Neutrino and Graviton Masses by a Phenomenological Mass Relation for Stable ParticlesDimitar T. ValevThe ratio between the proton and electron masses was shown to be close to the ratio between the shortest lifetimes of particles, decaying by the electromagnetic and strong interactions. The inherent property of each fundamental interaction is defined, namely the Minimal Lifetime of the Interaction (MLTI). The rest mass of the Lightest Free Massive Stable Particle (LFMSP), acted upon by … …Physics International, Vol. 6, Issue 2 · 25 Aug 2015 · 8,971 accessesView PDFCite
Research ArticleOpen accessIn the abstractEXTENDED MASS RELATION FOR SEVEN FUNDAMENTAL MASSES AND NEW EVIDENCE OF LARGE NUMBERS HYPOTHESISCurtis J. Forsythe, Dimitar T. ValevA previously derived mass relation has been extended to seven equidistant fundamental masses covering an extremely large mass range from ~10-69 to ~1053 kg. Six of these masses are successfully identified as mass of the observable universe, Eddington mass limit of the most massive stars, mass of hypothetical quantum “Gravity Atom” whose gravitational potential is equal to electrostatic potential e2/S, … …Physics International, Vol. 5, Issue 2 · 16 Jul 2014 · 8,274 accessesView PDFCite
Research ArticleOpen accessIn the abstractThree Fundamental Masses Derived by Dimensional AnalysisDimitar ValevThree new mass dimension quantities have been derived by dimensional analysis, in addition to the famous Planck mass mP ~10-8 kg. These masses have been derived by means of fundamental constants-the speed of light (c), the gravitational constant (G), the Plank constant (ħ) and the Hubble constant (H). The enormous mass m1 ~1053 kg practically coincides with the Hoyle-Carvalho formula … …Space Science International, Vol. 1, Issue 2 · 1 Apr 2014 · 10,439 accessesView PDFCite
Research ArticleOpen accessIn the abstractSTRINGENT LIMITS FOR THE MAGNETIC FIELD FROM EARLY UNIVERSE DYNAMOS IN RF2 COSMOLOGY WITH TORSIONL. C. Garcia de AndradeBamba et al. (2012) have obtained cosmological magnetic fields in teleparallel torsion theories of gravity that are not compatible with galactic dynamos. This result agrees with previous ones obtained by the author which shows Garcia de Andrade (1999) that anti-dynamo generalised theorem to torsion theories forbides such kind of dynamos to explain galactic magnetic fields of the order of µG. … …Physics International, Vol. 5, Issue 1 · 27 Mar 2014 · 7,857 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
