We search for analytical wave solutions of an electronically and biologically important model named as the Fitzhugh–Nagumo model with truncated m-fractional derivative, in which the expafunction and extended sinh-Gordon equation expansion(ESh GEE) schemes are utilized. The solutions obtained include dark, bright, dark-bright, periodic and other kinds of solitons. These analytical wave solutions are gained and verified with the use of mathematica software. These solutions do not exist in literature. Some of the solutions are demonstrated by 2D, 3D and contour graphs. This model is mostly used in circuit theory, transmission of nerve impulses, and population genetics. Finally, both the schemes are more applicable, reliable and significant to deal with the fractional nonlinear partial differential equations.

The aim of the present communication is to discuss the analytical solution for the unsteady flow of a third grade fluid which occupies the space y 〉 0 over an infinite porous plate. The flow is generated due to the motion of the plate in its own plane with an impulsive velocity V（t）. Translational symmetries in variables t and y are utilized to reduce the governing non-linear partial differential equation into an ordinary differential equation. The reduced problem is then solved using homotopy analysis method（HAm）. Graphs representing the solution are plotted and discussed and proper conclusions are drawn.

The behavior of a donor in the GaAs–GaAlAs quantum well wire represented by the morse potential is examined within the framework of the effective-mass approximation. The donor binding energies are numerically calculated for with and without the electric and magnetic fields in order to show their influence on the binding energies. moreover, how the donor binding energies change for the constant potential parameters(De, re, and a) as well as with the different values of the electric and magnetic field strengths is determined. It is found that the donor binding energy is highly dependent on the external electric and magnetic fields as well as parameters of the morse potential.

Dynamic operation and control of power system is being increasingly done with the help of phasor measurement unit(PmU) based wide area monitoring and control system. The data communication requirements for the PmU based applications are well addressed by IEEE C37.118.2 standard. However, IEC 61850 is now becoming a leading standard for power utility automation needs. A new part of IEC 61850, IEC 61850-90-5, specifying the IEEE C37.118.1 based synchrophasors data transfer according to IEC 61850, will lead to IEC 61850-90-5 based PmU communication networks. A novel IEC 61850-90-5 compliant communication model of PmU is proposed in this paper. We also present a comparative performance analysis of the PmU communication networks supporting the new synchrophasor standard for data transfer, i.e. IEC61850-90-5, and the existing standard, i.e. IEEE C37.118.2, for end to end(ETE) delay requirements for a modified IEEE 30 bus test system.
