In this paper, the tanh and sine–cosine methods are used to construct exact periodic and soliton solutions of nonlinear evolution equations arising in mathematical physics. Many new families of exact travelling wave solutions of the generalized Hirota–Satsuma coupled KdV system, generalized-Zakharov equations and (2 + 1)-dimensional Broer–Kaup– Kupershmidt(More)
Due to the emergence of very high-data-rate wireless communications, the adaptation of traditional diversity systems is required so that some performance is sacrificed for complexity reduction. With this goal in mind, we investigate the performance of muti-antenna multi-relay system when the generalized selection combining (GSC) is used to select and(More)
Extended Jacobian elliptic function expansion method is employed to find the ex¬act traveling wave solutions involving parameters for nonlinear evolution equations. When these parameters are taken to be special values, the solitary wave solutions are derived from the exact traveling wave solutions. It is shown that extended Jacobian elliptic func¬tion(More)
The nonlinear propagation of small but finite amplitude dust-acoustic solitary waves (DAWs) in magnetized collision less dusty plasma has been investigated. The fluid model is a four component magnetized dusty plasma, consisting of positive and negative dust species, isothermal electrons and ions in the presence of an external magnetic field. A reductive(More)
