Heliyon, 2019 We develop the new Kumaraswamy Log-Logistic Weibull (KLLoGW) distribution by combining the Kumaraswamy and Log-logistic Weibull distributions. This new model is flexible for modelling lifetime data. Some statistical properties including quantile function,

Using theoretical-computational conflicts to enrich the concept name of derivative [PDF]
, 2003 Recent literature has pointed out pedagogical obstacles associated with the use of computational environments in the learning of mathematics. In this paper, we focus on the pedagogical role of the computer's inherent limitations in the development of ...

Solutions of nonlinear real world problems by a new analytical technique
Heliyon, 2018 Here a new analytical scheme is presented to solve nonlinear boundary value problems (BVPs) of higher order occurring in nonlinear phenomena. This method is called second alternative of Optimal Homotopy Asymptotic Method.

Pincherle's theorem in Reverse Mathematics and computability theory
, 2020 We study the logical and computational properties of basic theorems of uncountable mathematics, in particular Pincherle's theorem, published in 1882. This theorem states that a locally bounded function is bounded on certain domains, i.e. one of the first

Numerical investigation of bubbles coalescence in a shear flow with diffuse-interface model
Heliyon, 2018 In this article, we apply the diffuse-interface model [developed by Shah and Yuan (2011) [21]] for collision and coalescence of two bubbles in a linear shear flow.
