Research ArticleOpen accessIn the keywordsMachine Motion Equations at the Internal Combustion Heat EnginesFlorian Ion T. PetrescuThis paper presents an algorithm for setting the dynamic parameters of the classic main mechanism of the internal combustion engines. One presents the dynamic, original, machine motion equations. The equation of motion of the machine that generates angular speed of the shaft (which varies with position and rotation speed) is deduced by conservation kinetic energy of the machine. An additional … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 21 Apr 2015 · 9,387 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhysical and Geometrical Effects on the Vibratory Pattern of a Pipe Carrying Fluid FlowDahmane Mouloud, Samir Zahaf, Mawhoub Soubih et al.In this research, the first natural frequencies and critical velocities of a fluid flow-conveying pipe are obtained with finite element method. By discretizing the structure wall and fluid flow, starting from beam type with two degrees of freedom per node. We determine the equation of motion from the fluid-structure coupling using Lagrange energy principle. Parameters frequencies and critical velocity of … …Current Research in Bioinformatics, Vol. 9, Issue 1 · 22 Oct 2020 · 11,396 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOscillatory Dynamical Switching System of Bulk FerroelectricsM. N.A. Halif, S. Daud, Junaidah OsmanThis study gives a detailed account of calculation of the bulk ferroelectric (FE) oscillatory dynamical system switching to first and second-order phase transition, respectively. All the formalism is delineated in the framework of Landau free-energy expansion and Landau-Khalatnikov (LK) equation of motion where the effect of external energy may affray FE atoms similar to the spring damped oscillatory system. Here … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,677 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPresenting a New Equation that Accurately Determines the Size of a Moving Elementary ParticleFlorian Ion Tiberiu PetrescuThe paper briefly presents a new Eq. (9). The role of Eq. (9) is to accurately determine the size of a moving elementary particle, depending on its velocity (or particle energy). Although Eq. (9) has a general character, it can be applied to any elementary particle in motion to determine the size of that particle, in the study, it was … …American Journal of Applied Sciences, Vol. 19, Issue 1 · 24 Nov 2022 · 6,475 accessesView PDF Cite
