We extend Schoenberg’s family of polynomial splines with uniform knots to all fractional degrees α > −1. These splines, which involve linear combinations of the one-sided power functions x+ = max(0, x) α, are α-Hölder continuous for α > 0. We construct the corresponding B-splines by taking fractional finite differences and provide an explicit characterization in both time and frequency domains....

the complex-step derivative approximation is applied to compute numerical derivatives. in this study, we propose a new formula of fractional complex-step method utilizing jumarie definition. based on this method, we illustrated an approximate analytic solution for the fractional cauchy-euler equations. application in image denoising is imposed by introducing a new fractional mask depending on s...

This paper presents some new propositions related to the fractional order h-difference operators, for case of general quadratic forms and polynomial type, which allow proving stability systems, by means discrete Lyapunov direct method, using functions, functions any positive integer order, respectively. Some examples are given illustrate these results.

Phase locked loops for fractional frequency synthesis typically use Digital $\Delta \Sigma $ Modulators (DDSMs) as their divider controllers. Different types and configurations of DDSMs have been presented in the past which distinctiv...

A vector is dyadic if each of its entries a rational number, i.e., an integer multiple $\frac{1}{2^k}$ for some nonnegative $k$. We prove that every clean clutter with covering number at least two has fractional packing value two. This result best possible, there exist clutters three and no three. Examples include ideal clutters, binary without intersecting minor. Our proof constructive leads n...

let $g$ be a simple graph of order $n$‎. ‎we consider the‎ ‎independence polynomial and the domination polynomial of a graph‎ ‎$g$‎. ‎the value of a graph polynomial at a specific point can give‎ ‎sometimes a very surprising information about the structure of the‎ ‎graph‎. ‎in this paper we investigate independence and domination‎ ‎polynomial at $-1$ and $1$‎.
