In this note we study some properties of an new inverse Weibull cumulative function
proposed by Afify, Shawky and Nassar [1]. More precisely, we prove estimates for the” …

In this article we study the Hausdorff approximation of the Haar scaling function by sigmoidal
scaling functions. We prove upper and lower estimates for the value of the Hausdorff …

Following the ideas given in [2] in this paper we define a hypothetical piecewise smooth
generalized sigmoidal model Q (q1 (t), q2 (t)) using the generalized logistic model. We will …

One of the main tasks of modern education is to form in students the knowledge and
competencies applicable in different fields, to increase their interest in learning, to form and …

Some new facts about a simple one-parameter unit distribution, called the unit-Rayleigh
