A problem of propagation of strong plane and converging shock wave is studied in a mixture of a gas and small solid particles. It is assumed that the solid particles are continuously distributed in the gas. Jump conditions ...

In this paper, the axi-symmetric peristaltic transport of a viscous incompressible visco-elastic fluid has been investigated through a circular tube whose cross section changes along the length. The wall motion is governed ...

The article presents a mathematical model of nonlinear reaction diffusion equation with fractional time derivative α (0 < α< 1) in the form of a rapidly convergent series with easily computable components. Fractional ...

The aim of present paper is to obtain the approximate analytical solution of time fractional Harry Dym equation by using homotopy perturbation method (HPM). The beauty of the paper is error analysis which shows that our ...

In this paper, the solution of the one dimensional moving boundary problem with periodic boundary conditions is obtained with the help of variational iterational method. By using initial and boundary values, the explicit ...

The investigation is to explore the transportation of a viscoelastic fluid with fractional Burgers' model by peristalsis through a channel under the influence of wall slip condition. This analysis has been carried out under ...

The Bianchi Type-I Universe filled with dark energy from a wet dark fluid has been considered. A new equation of state for the dark energy component of the Universe has been used. It is modeled on the equation of state p ...

The effect of dispersal of ferroelectric ceramic materials Ba0.70Sr0.30TiO3 (Tc ≈ 30°C) and Ba0.88Sr0.12TiO3 (Tc ≈ 90°C) on the ionic conductivity of an ion conducting polymer electrolyte (PEO:NH4I) is reported. The addition ...

Multiple objective programming problems with the concept of weak minima are extended to multiple objective variational problems. A number of weak, strong, and converse duality theorems are given under a variety of generalized ...

In a recent work, cited in the Introduction, a concept of generalized pseudoconvexity was used to obtain optimality results in nonlinear programming. In the present work we give sufficient optimality conditions, in the ...
