Nonlinear dynamics of a position-dependent mass-driven Duffing-type oscillator
TL;DR: In this article, the authors examine some nontrivial consequences that emerge from interpreting a position-dependent mass (PDM)-driven Duffing oscillator in the presence of a quartic potential.

TL;DR: In this paper, the authors examine some nontrivial consequences that emerge from interpreting a position-dependent mass (PDM) driven Duffing oscillator in the presence of a quartic potential.
Journal ArticleDOI
New exact solutions of a generalized shallow water wave equation
TL;DR: In this article, an extended elliptic function method is proposed and applied to the generalized shallow water wave equation and the derived new solutions include rational, periodic, singular and solitary wave solutions.
Journal ArticleDOI
Effect of CeO2 on the sintering behaviour of zirconia–alumina composite
TL;DR: In this paper, a composite containing equimolar proportion of ZrO 2 and Al 2 O 3 having higher reactivity has been synthesized by the wet interaction of inorganic salts in aqueous phase.
Journal ArticleDOI
Reply to Comment on 'Nonlinear dynamics of a position-dependent mass-driven Duffing-type oscillator'
TL;DR: In this article, an extended Lagrange equation involving a non-conservative force term when the particle mass varies with position has been proposed, which yields precisely the form of Newton's equation expected for a particle possessing a position-dependent mass.
