A note on the weighted harmonic-geometric-arithmetic means inequalities [PDF]

Mathematical Inequalities & Applications, 2012
In this note, we derive non trivial sharp bounds related to the weighted harmonic-geometric-arithmetic means inequalities, when two out of the three terms are known. As application, we give an explicit bound for the trace of the inverse of a symmetric positive definite matrix and an inequality related to the coefficients of polynomials with positive ...

Not all voxels are created equal: Reducing estimation bias in regional NODDI metrics using tissue-weighted means

NeuroImage, 2021
Neurite orientation dispersion and density imaging (NODDI) estimates microstructural properties of brain tissue relating to the organisation and processing capacity of neurites, which are essential elements for neuronal communication.

Ecological Potential Evaluation for the Irrigated Agriculture Using the Current Models and the New Model of EMOLUP for the Firozabad County [PDF]

پژوهش‌های آبخیزداری, 2022
The process of assessing the ecological potential of the land, or measuring the potential of the land, is an important step before implementation. The Firoozabad Township is located in the Province of Fars. Irrigated farming provides the major income for

On weighted quasi-arithmetic means which are convex [PDF]

Mathematical Inequalities & Applications, 2019
Summary: We study convexity in the class of weighted quasi-arithmetic means. It turns out that their convexity depends only on the generator, neither on weights, nor on the number of variables. Connections between the convexity of a mean and the convexity of its increasing generators are considered.

An Aggregation Metric Based on Partitioning and Consensus for Asymmetric Distributions in Likert Scale Responses

Mathematics, 2022
A questionnaire is a basic tool for collecting information in survey research. Often, these questions are measured using a Likert scale. With multiple items on the same broad object, these codes could be summed or averaged to give an indication of each ...

Refining and reversing the weighted arithmetic–geometric mean inequality involving convex functionals and application for the functional entropy

Journal of Inequalities and Applications, 2020
In this paper, we present some refinements and reverses for some inequalities involving the weighted arithmetic mean and the weighted geometric mean of two convex functionals. Inequalities involving the Heinz functional mean are also obtained.

On Kedlaya-type inequalities for weighted means

Journal of Inequalities and Applications, 2018
In 2016 we proved that for every symmetric, repetition invariant and Jensen concave mean M $\mathscr{M}$ the Kedlaya-type inequality A(x1,M(x1,x2),…,M(x1,…,xn))≤M(x1,A(x1,x2),…,A(x1,…,xn)) $$ \mathscr{A} \bigl(x_{1},\mathscr{M}(x_{1},x_{2}), \ldots ...
