in this paper, a new fractional sub-equation method is proposed for finding exact solutions of fractional partial differential equations (fpdes) in the sense of modified riemann-liouville derivative. with the aid of symbolic computation, we choose the space-time fractional zakharov-kuznetsov-benjamin-bona-mahony (zkbbm) equation in mathematical physics with a source to illustrate the validity a...

Conceptual modelling methods such as ER (Chen, 1976), EER (Elmasri and Navathe, 1994; Gogolla, 1994), KISS (Kristen, 1994), NIAM (Nijssen and Halpin, 1989), OOSA (Embley, Kurtz, and Woodfield, 1992) and ORM (Halpin, 2001) have traditionally been developed with the aim of providing conceptual models of database structures. More recently, however, such modelling methods have shown their use for m...

In this paper a modification of He's variational iteration method (VIM) has been employed to solve Dung and Riccati equations. Sometimes, it is not easy or even impossible, to obtain the first few iterations of VIM, therefore, we suggest to approximate the integrand by using suitable expansions such as Taylor or Chebyshev expansions.
