A force decomposition (FD) method previously used for two-body interactions is extended to three-body interactions. Three modified force decomposition strategies, namely cyclic decomposition (CD), balanced cyclic decomposition (BD) and precise decomposition (PD) are proposed. They are based on the decomposition of the three-body force matrix and the precise estimation of triplets involved in ea...

Nonlinear evolution equations have a major role in various scientific and engineering fields, such as fluid mechanics, plasma physics, optical fibers, solid state physics, chemical kinematics, chemical physics and geochemistry. Nonlinear wave phenomena of dispersion, dissipation, diffusion, reaction and convection are very important in nonlinear wave equations. In recent years, quite a few meth...

in recent years, researchers have become interested in examining the effect of pettlep imagery on motor performance and how pettlep imagery can improve the performance. the aim of this study was to compare the effect of pettlep imagery and balance practice on dynamic balance in the elderly. participants were 42 male elderly in arak city. they were divided into 4 groups based on the scores of dy...

Problem statement: A homotopy method has proven to be reliable for computing all of the isolated solutions of a multivariate polynomial system. The multi-homogeneous Bézout number of a polynomial system is the number of paths that one has to trace in order to compute all of its isolated solutions. Each partition of the variables corresponds to a multi-homogeneous Bézout number. It is a crucial ...
