EditorialOpen accessIn the abstractRETRACTED: Existence and Non-Existence of Super Mean Labeling on Star GraphsG. Uma Maheswari, Suzan Jabbar Obaiys, G. Margaret Joan Jebarani et al.This article has been retracted after careful consideration and internal assessment following a formal investigation into allegations of plagiarism. After careful review, it was found that substantial portions of the article—including theorems, definitions, diagrams, and proofs—were reproduced with minimal modification from previously published works without appropriate citation or acknowledgment. The reused content includes, but is not limited to, material from … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 13 Nov 2020 · 6,147 accessesView PDFCite
Research ArticleOpen accessIn the abstractExplosion of the Science Modification of Newtonian Dynamics Via Mach’s Inertia Principle and Generalization in Gravitational Quantum Bound Systems and Finite Range of the Gravity-Carriers, Consistent Merely On the Bosons and the FermionsMohsen LutephyNewtonian gravity is modified here via Mach's inertia principle (inertia fully governed by universe) and it is generalized to gravitationally quantum bound systems, resulting scale invariant fully relational dynamics (mere ordering upon actual objects), answering to rotation curves and velocity dispersions of the galaxies and clusters (large scale quantum bound systems), successful in all dimensions and scales from particle to … …Physics International, Vol. 11, Issue 1 · 10 Aug 2020 · 7,782 accessesView PDFCite
Research ArticleOpen accessIn the abstractFree Particle Spin SpeedNicolae Petrescu, Florian Ion Tiberiu PetrescuThe electron and the proton are stable particles, compounds of the atoms, which in turn are the macroscopic scale components. A heated metal plate becomes the source of a cloud of electrons, which by an acceleration in an electromagnetic field becomes an electron beam. Protons are obtained by ionized hydrogen atoms; as the mass of the electron is negligibly small … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 5 Jul 2019 · 7,775 accessesView PDFCite
Research ArticleOpen accessIn the abstractElementary Structure of Matter can be Studied with New Quantum ComputersNicolae Petrescu, Florian Ion Tiberiu PetrescuMuch has been talked about quantum computers. Today they are working on difficult simulations, so we can already congratulate the college of researchers at the Oak Ridge National Laboratory as the world's first to successfully simulate an atomic nucleus using a quantum computer. The results that were published in the physical examination letters demonstrate the huge capacity of quantum systems … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 25 Jun 2018 · 7,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Elite Pool-Based Big Bang-Big Crunch Metaheuristic for Data ClusteringIbrahim Al-Marashdeh, Ghaith M. Jaradat, Masri Ayob et al.This paper delves into the capacity of enhanced Big Bang-Big Crunch (EBB-BC) metaheuristic to handle data clustering problems. BB-BC is a product of an evolution theory of the universe in physics and astronomy. Two main phases of BB-BC are big bang and big crunch. The big bang phase involves a creation of a population of random initial solutions, while in … …Journal of Computer Science, Vol. 14, Issue 12 · 19 Jun 2018 · 7,879 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Development Design of Low Current Measurement with Noise Reduction for High-Resolution SystemNdalla Essengue Gloire, Wembe Tafo Evariste, Djamet Yimga Arnaud et al.The treatment of inoperable cancers in the therapy terminal in Lanzhou-China, which is located at the Institute of Modern Physics (IMP), permits to work on the actual front-end readout. The availability of detailed noise spectral density characteristics for the OPA amplifier helps to develop the noise error analysis for high-resolution. This work focused on the noise model of the detector-preamplifier, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 18 May 2018 · 8,424 accessesView PDFCite
Research ArticleOpen accessIn the abstractTriton for Nuclear FusionRaffaella Aversa, Relly Victoria Petrescu, Antonio Apicella et al.In the nuclear fusion process that is permanently produced in the stars (suns) there is a thermonuclear reaction that uses as the main raw material the very first isotope of hydrogen, namely the Protium. This process is possible due to the huge temperatures and the unimaginably high pressures existing inside a star. At very high temperatures and pressures, matter begins … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 16 Dec 2017 · 8,917 accessesView PDFCite
Research ArticleOpen accessIn the abstractHysteresis, resonant oscillations and bifurcation mode of a system modeled by a forced modified Van der Pol-Duffing oscillatorJean Bio Chabi Orou, Clément Hodévèwan Miwadinou, Laurent Amoussou Hinvi, Adjimon Vincent MonwanouNonlinear oscillations and its applications in physics, chemistry, engineering, biophysics, communications are studied with some analytical, numerical and experimental methods. In the present paper, hysteresis, resonant oscillations and bifurcation mode of a system modeled by a forced modified Van der Pol-Duffing oscillator are considered. The plasma oscillations are considered and are described by a nonlinear differential equation. By using the … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 23 Oct 2017 · 7,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation Model for Feasibility Studies on Bioremediation of Uranium Mill Tailings using Hyper Accumulator Chrysopogon zizanioidesH. Shanmugasundaram, Sathesh Kumar Annamalai, Kantha Deivi Arunachalam et al.Contamination of environment by uranium is expected in places where mining of uranium ore and processing, nuclear testing and reactor operations when the control measures are not effective. The daughter radionuclides of the ores, chemical additives and residual uranium are the maincomponents of processed waste from uranium industries. The bioremediation of contaminated areas using plant species or group of the … …American Journal of Environmental Sciences, Vol. 12, Issue 6 · 11 Dec 2016 · 8,872 accessesView PDFCite
