The nonlinear vibration and dispersive wave systems with cross-kink and solitary wave solutions

Abstract

This paper investigates the cross-kink and solitary wave solutions to the nonlinear vibration and dispersive wave systems. The solutions include periodic, cross-kink and solitary wave solutions. The bilinear form is considered in terms of Hirota derivatives. Accordingly, we utilize the Cole–Hopf algorithm to get the exact solutions of the [Formula: see text]-dimensional modified dispersive water-wave system. The analytical treatment of cross-kink, solitary wave solutions is studied and plotted in three forms of two, density and three-D plots. A nonlinear vibration system will be investigated. Employing appropriate mathematical assumptions, the novel kinds of the cross-kink and solitary wave solutions are derived and constructed in view of the combination of kink, periodic and soliton for cross-kink and also a combination of two kinks in terms of exponential functions for solitary of the governing equation. To achieve this, the illustrative example of the [Formula: see text]-D modified dispersive water-wave system is furnished to exhibit the feasibility and reliability of the procedure utilized in this research. The trajectory solutions of the traveling waves are presented explicitly and graphically. The effect of the free parameters on the behavior of designed figures of a few obtained solutions for two nonlinear rational exact cases was also considered. By comparing the suggested technique with the other existing schemes, the results present that the execution of this technique is concise, simple and straightforward.

A device for detecting current asymmetry in a three-phase alternating current system

“…When the currents 𝐼𝐼 1 , 𝐼𝐼 2 , and 𝐼𝐼 3 3 are equal to each other, then their magnetic fluxes Ф 1 , Ф 2 , and Ф 3 are equal, and the difference magnetic fluxes are zero, i.e.∆Ф 12 = 0 and∆Ф 23 = 0. Therefore, the EMF of 𝐸𝐸 𝑜𝑜𝑜𝑜𝑜𝑜12 and 𝐸𝐸 𝑜𝑜𝑜𝑜𝑜𝑜23 at the ends of the output windings 9 are also zero [15,16].…”

Research primary processing of live of silk cocoons in a solar installation

“…In all the leading silk-growing countries of the world, including in our republic, conveyor cocoon dryers are used for soaking cocoons, which process cocoons with hot air. Coconut dryers of the SK-150K type installed in our republic, 85-90 kg of diesel fuel and 70-75 kW of electric energy are consumed to lure 1 ton of live cocoons [8][9][10].…”
