Nonuniformly weighted Schwarz smoothers for spectral element multigrid

open access: yes, 2016
A hybrid Schwarz/multigrid method for spectral element solvers to the Poisson equation in $\mathbb R^2$ is presented. It extends the additive Schwarz method studied by J. Lottes and P. Fischer (J. Sci. Comput.

A non-calculus approach to solving the utility maximization problem using the Cobb-Douglas and CES utility function

open access: yesCroatian Operational Research Review, 2015
This paper proposes a new original non-calculus method to solving the utility maximization problem using the Cobb-Douglas and the CES utility functions, and incorporating the weighted arithmetic-geometric-mean inequality (weighted AM-GM inequality) and ...

The Generalized Hybrid Averaging Operator and its Application in Decision Making // La media generalizada híbrida y su aplicación en la toma de decisiones [PDF]

open access: yesRevista de Métodos Cuantitativos para la Economía y la Empresa, 2010
We present the generalized hybrid averaging (GHA) operator. It is a new aggregation operator that generalizes the hybrid averaging (HA) operator by using the generalized mean. Thus, we are able to generalize a wide range of mean operators such as the HA,

Moyennes effectives de fonctions multiplicatives complexes

open access: yes, 2020
We establish effective mean-value estimates for a wide class of multiplicative arithmetic functions, thereby providing (essentially optimal) quantitative versions of Wirsing's classical estimates and extending those of Hal\'asz.

On a functional equation containing four weighted arithmetic means

open access: yesBanach Journal of Mathematical Analysis, 2008
The author offers a complete discussion and solution of the functional equation \[ f\big(\alpha x+(1-\alpha)y\big)+f\big(\beta x+(1-\beta)y\big) =f\big(\gamma x+(1-\gamma)y\big)+f\big(\delta x+(1-\delta)y\big), \] which holds for all \(x,y\in I\), where \(I\) is a non-void open real interval.

Logarithmic mean and weighted sum of geometric and anti-harmonic means

open access: yesJournal of Numerical Analysis and Approximation Theory, 2012
We consider the problem of finding the optimal values \(\alpha,\ \beta\in\mathbb{R}\) for which the inequality\[\alpha G(a,b)+(1-\alpha)C(a,b)

Additive inequalities for weighted harmonic and arithmetic operator means

open access: yesAnnales Universitatis Mariae Curie-Sklodowska, sectio A – Mathematica, 2019
In this paper we establish some new upper and lower bounds for the difference between the weighted arithmetic and harmonic operator means under various assumptions for the positive invertible operators A, B. Some applications when A, B are bounded above and below by positive constants are given as well.

Bilateral inequalities for means

open access: yesJournal of Numerical Analysis and Approximation Theory, 2013
Let \(\left(M_{1},M_{2},M_{3}\right) \) be three means in two variables chosen from \(H\), \(G\), \(L\), \(I\), \(A\), \(Q\), \(S\), \(C\) so that \[ M_{1}(a,b)

Standardization of Weightage Assigned to Different Segments of the Hand X-ray for Assessment of Bone Age by the Greulich–Pyle Method

open access: yesIndian Journal of Endocrinology and Metabolism
Introduction: Bone age (BA) assessment is important in evaluating disorders of growth and puberty; the Greulich and Pyle atlas method (GP) is most used. We aimed to determine the weightage to be attributed by raters to various segments of the hand x-ray,
