This work investigates three nonlinear equations that describe waves on the oceans which are the Kadomtsev Petviashvili-modified equal width(KP-MEW)equation,the coupled Drinfel’d-Sokolov-Wilson(DSW)equation,and the Benjamin-Ono(BO)equation using the modified(G′/G^(2))-expansion approach.The solutions of proposed equations by modified(G′/G^(2))-expansion approach can be trigonometric,hyperbolic,or rational solutions.As a result,some new exact solutions are obtained and plotted. 展开更多

The polycrystalline sample of complex tungsten-bronze type compound(Na_(2)Pb_(2)La_(2)W_(2)Ti_(4)Ta_(4)O_(30))was prepared by a high-temperature solid-state reaction technique.Room temperature preliminary structural study using X-ray diffraction(XRD)data exhibits the formation of a single-phase new compound.The SEM micrograph of the compound exhibits non uniform rectangular grains distributed throughout the sample surface.Detailed studies of dielectric parameters(εr,tanδ)as a function of temperature and frequency,and P-E hysteresis(spontaneous polarization)confirmed the existence of ferroelectricity in the material.Complex impedance spectroscopy analysis,carried out as a function of frequency at different temperatures,established a correlation between the microstructure and electrical properties of the material.The electrical relaxation process occurring in the material is temperature dependent.The activation energy found from the Arrhenius plot that the conduction process in the material is of mixed type.The nature of frequency dependence of ac conductivity suggests that the material obeys Jonscher’s universal power law. 展开更多
