the aim of this paper is to study the high order difference scheme for the solution of a fractional partial differential equation (pde) in the electroanalytical chemistry. the space fractional derivative is described in the riemann-liouville sense. in the proposed scheme we discretize the space derivative with a fourth-order compact scheme and use the grunwald- letnikov discretization of the ri...

A novel large input range source-follower based bi-quad filter cell is proposed offering an additional degree of freedom to the position of the poles and zeros. Simulation results of a 4th order fully differential elliptical filter in a 0.13μm CMOS technology confirm a power consumption of 160μA @ 1.2V, an IIP3 of 6.3 dBm and a steepness of 177 db/decade.

Some methods for the convergence acceleration of the Møller-Plesset perturbation series for the correlation energy are discussed. The order-by-order summation is less effective than the Feenberg series. The latter is obtained by renormalizing the unperturbed Hamilton operator by a constant factor that is optimized for the third order energy. In the fifth order case, the Feenberg series can be i...

In this article we recall a remarkable result stated as "For fixed ?, 0 < ? 1, the set of all bounded statistically convergent sequences order is closed linear subspace m (m real endowed with sup norm)" by Bhunia et al. (Acta Math. Hungar. 130 (1-2) (2012), 153-161) and to develop objective perception demonstrate that may not form in other sequence spaces. Also determine two different spaces...
