A closed-form expression of effective permittivity with spherically symmetric function for honeycomb structure

open access: yesMaterials Research Express, 2021
A novel closed-form expression for predicting the equivalent electromagnetic parameters of the honeycomb structure is proposed. It is obtained by approximating the correlation terms in the derivation of the strong fluctuation theory with the integral of ...

THE USAGE AND UNDERSTANDING OF ANGLICISMS BY BOSNIAN EFL USERS [PDF]

open access: yesHuman Research in Rehabilitation, 2023
This study aimed to explore the use of nominal and verbal Anglicisms by Bosnian high school students, the students’ familiarity with these Anglicisms and their attitudes towards them and it also aimed to see whether these factors vary with respect to ...

Equivalent forms for a poset to be modular poset

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2021
The notion of modular and distributive posets which generalize the corresponding notions from the lattice theory are introduced by J. Larmerova and J. Rachnek. Later some extended results of uniquely complemented lattice are derived to uniquely complemented posets. Now, in this paper, some equivalent conditions for a poset to be modular poset are given.

Lyapunov Equivalent Representation Form of Forced, Damped, Nonlinear, Two Degree-of-Freedom Systems

open access: yesApplied Sciences, 2018
The aim of this paper focuses on finding equivalent representation forms of forced, damped, two degree-of-freedom, nonlinear systems in the sense of Lyapunov by using a nonlinear transformation approach that provides decoupled, forced, damped, nonlinear ...

Topological equivalence of real binary forms [PDF]

open access: yesProceedings of the American Mathematical Society, 1991
Necessary and sufficient conditions are given for two real binary homogeneous polynomials to be equivalent under a continuous change of variables, and for the forms to be equivalent under a continuous change of variables that is differentiable (or that is real-analytic) away from the origin.

Estimation of Form Drag Caused by Rigid Vegetation Based on Equivalent Roughness

open access: yesIEEE Access, 2019
The flow structure over vegetation in ecological channel is rather complex and the resistance caused by vegetation is affected by many factors, such as discharge, flow depth, vegetation density and patch arrangement types, etc.

The English and Chinese language versions of the Short Form 12-item Health Survey are equivalent

open access: yesHealth and Quality of Life Outcomes, 2021
Background The Short Form 12-item Health Survey (SF-12v2) was originally developed in English, but it is also available in Hong Kong (HK) Chinese. While both language versions had their measurement properties well assessed in their respective populations,

A new Hilbert-type integral inequality and the equivalent form

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
We give a new Hilbert-type integral inequality with the best constant factor by estimating the weight function. And the equivalent form is considered.

On a reverse Mulholland’s inequality in the whole plane

open access: yesJournal of Inequalities and Applications, 2018
By introducing multi-parameters, applying the weight coefficients and Hermite–Hadamard’s inequality, we give a reverse of the extended Mulholland inequality in the whole plane with the best possible constant factor.
