This article uses the Yang transform decomposition method and homotopy perturbation to study seventh-order time-fractional Sawada–Kotera–Ito equation. The fractional derivative is taken into account in Caputo sense. We used with Adomian process procedure on problem obtain solution. looked at a single case contrasted it actual result validate methodologies. These techniques create recurrence rel...

There have been several recent works on developing moving mesh methods for solving phase-field equations. However, it is observed that some of these moving mesh solutions are essentially different with the solutions on very fine fixed meshes. One of the purposes of this work is to understand the reason for the differences. We carried out numerical sensitivity studies systematically in this pape...

The relativistic shock layer problem was numerically analyzed by using two relativistic Boltzmannkinetic equations. One is Marle model, and the other is Anderson-Witting model. As with Marle model, the temperature of the gain term was determined from its relation with the dynamic pressure in the framework of 14-moments theory. From numerical results of the relativistic shock layer problem, beha...

The current national standard for strength grading in Spain is based on a visual classification, which, softwood species with small cross-sections (with thickness equa tol or less than 70 mm), establishes two different grades (ME-1 and ME-2). These are assigned to the classes C24 C18, respectively, maritime radiata pines, C27 C18 Scots pine, according European EN-1912:2012. production of engine...

In this paper, we study the linear stability of elliptic rhombus solutions, which are Keplerian homographic solution with central configurations in classical planar four-body problems. Using $\omega$-Maslov index theory and trace formula, prove instability solutions if shape parameter $u$ eccentricity orbit $e$ satisfy $(u,e) \in (1/\sqrt{3}, u_2)\times [0, \hat{f}(\frac{27}{4})^{-1/2})\cup (u_...
