This paper presents a new function expansion method for finding traveling wave solutions of a nonlinear equations and calls it the ( G′ G ) -expansion method, given by Wang et al recently. As an application of this new method, we study the well-known Sawada-Kotera-Kadomtsev-Petviashivili equation and Bogoyavlensky-Konoplechenko equation. With two new expansions, general types of soliton solutio...

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...

In this paper, a new (2 + 1)-dimensional nonlinear evolution equation is investigated. This called the Kadomtsev–Petviashvili–Sawada–Kotera–Ramani equation, which can be seen as two-dimensional extension of Korteweg–de Vries–Sawada–Kotera–Ramani equation. By means Hirota’s bilinear operator and binary Bell polynomials, form Bäcklund transformation are obtained. Furthermore, by application Hopf-...

Scaling similarity solutions of three integrable PDEs, namely the Sawada-Kotera, fifth order KdV and Kaup-Kupershmidt equations, are considered. It is shown that the resulting ODEs may be written as non-autonomous Hamiltonian equations, which are time-dependent generalizations of the well-known integrable Hénon-Heiles systems. The (time-dependent) Hamiltonians are given by logarithmic derivativ...

Large discrepancy of the p-wave phase shift data δ1(ν) of the π-π scattering from those of the dispersion calculation is pointed out. In order to determine which is correct, the pion form factor Fπ(ν), which is the second source of information of the phase shift δ1(ν), is used. It is found that the phase shift obtained from the dispersion is not compatible with the data of the pion form factor....

To the Editor: A proposed method of determining nonspecific binding parameters for a receptor binding radioli­ gand is to measure the pharmacokinetics of a ste­ reoisomer whose affinity for receptor is lower (Wagner, 1986). We have investigated a specific ex­ ample to gain a better understanding of when the parameters derived from the stereoisomer may rea­ sonably be used to estimate the nonspe...

This paper proposes a method for estimating the direction of arrival (DOA) of multiple source signals for an underdetermined situation, where the number of sources N exceeds the number of sensors M (M < N). Some DOA estimation methods have already been proposed for underdetermined cases. However, since most of them restrict their microphone array arrangements, their DOA estimation ability is li...
