The combination of graphene and nickel oxide nanoparticles yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. In cyclic voltammetry studies, in the presence of epinephrine, nickel oxide / graphene  composite modified electrode shows a significantly higher current response for epinephrine oxidation. Based on differenti...

In 1986 S. Sattolo introduced a simple algorithm for uniform random generation of cyclic permutations on a fixed number of symbols. Recently, H. Prodinger analysed two important random variables associated with the algorithm, and found their mean and variance. H. Mahmoud extended Prodinger’s analysis by finding limit laws for the same two random variables.The present article, starting from the ...

We analyze the one dimensional Cucker–Smale (in short CS) model with a weak singular communication weight ψ(x)=|x|−β β∈(0,1). first establish global-in-time existence of measure-valued solutions to kinetic CS equation. For this, we use proper change variable reformulate particle as first-order system and provide uniform-in-time stability for that system. then extend this estimate By using estim...

The aim of the present work is to show that recent results authors on approximation distributions sums independent summands by infinitely divisible laws convex polyhedra can be shown via an alternative class approximating distributions. We will also generalize infinite-dimensional case.
