On New Means with Interesting Practical Applications: Generalized Power Means
Mathematics, 2021 Means of positive numbers appear in many applications and have been a traditional matter of study. In this work, we focus on defining a new mean of two positive values with some properties which are essential in applications, ranging from subdivision and

Using Permutations for Hierarchical Clustering of Time Series
Entropy, 2019 Two distances based on permutations are considered to measure the similarity of two time series according to their strength of dependency. The distance measures are used together with different linkages to get hierarchical clustering methods of time ...

Reducing Chaos and Bifurcations in Newton-Type Methods
Abstract and Applied Analysis, 2013 We study the dynamics of some Newton-type iterative methods when they are applied of polynomials degrees two and three. The methods are free of high-order derivatives which are the main limitation of the classical high-order iterative schemes.

Journal of Inequalities and Applications, 2019 In this paper we study the curvature term for the Lagrange and PPH (Amat et al. in Found. Comput. Math. 6:193–225, 2006 and Ortiz and Trillo in Preprint, arXiv:1811.10566, 2018) reconstruction operators in uniform and nonuniform meshes.

Collocation Methods for High-Order Well-Balanced Methods for Systems of Balance Laws
Mathematics, 2021 In some previous works, two of the authors introduced a technique to design high-order numerical methods for one-dimensional balance laws that preserve all their stationary solutions. The basis of these methods is a well-balanced reconstruction operator.

Parameters and fractional factors in different settings
Journal of Inequalities and Applications, 2019 In computer networks, the feasibility of data transmission can be measured in terms of fractional factor model, and specifically the framework of fractional critical deleted graph can express the setting when certain sites and channels are unavailable at
