Minimization of the threshold voltage parameter of the co-doped ZnO doped liquid crystals by machine learning algorithms

open access: yesScientific Reports, 2023
This study aims to examine the influence of the co-doped semiconductor nanostructure (Al-Cu):ZnO on the electro-optical properties of the E7 coded pure nematic liquid crystal structures and minimize the threshold voltage of pure E7 liquid crystal.

Mixed-Gas Selectivity Based on Pure Gas Permeation Measurements: An Approximate Model

open access: yesMembranes, 2021
An approximate model based on friction-coefficient formalism is developed to predict the mixed-gas permeability and selectivity of polymeric membranes. More specifically, the model is a modification of Kedem’s approach to flux coupling.

Bounds for the minimum distance function

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021
Let I be a homogeneous ideal in a polynomial ring S. In this paper, we extend the study of the asymptotic behavior of the minimum distance function δI of I and give bounds for its stabilization point, rI, when I is an F -pure or a square-free monomial ...

Universal quantum computation with ideal Clifford gates and noisy ancillas (14 pages) [PDF]

open access: yes, 2004
We consider a model of quantum computation in which the set of elementary operations is limited to Clifford unitaries, the creation of the state |0>, and qubit measurement in the computational basis.

Supported Ionic Liquid Membranes and Ion-Jelly® Membranes with [BMIM][DCA]: Comparison of Its Performance for CO2 Separation

open access: yesMembranes, 2015
In this work, a supported ionic liquid membrane (SILM) was prepared by impregnating a PVDF membrane with 1-butyl-3-methylimidazolium dicyanamide ([BMIM][DCA]) ionic liquid.

Purity of the ideal of continuous functions with pseudocompact support

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
Let CΨ(X) be the ideal of functions with pseudocompact support and let kX be the set of all points in υX having compact neighborhoods. We show that CΨ(X) is pure if and only if βX−kX is a round subset of βX, CΨ(X) is a projective C(X)-module if and ...

Notes on Approximately Pure Submodules

open access: yesمجلة بغداد للعلوم, 2013
Let R be a commutative ring with identity 1 and M be a unitary left R-module. A submodule N of an R-module M is said to be approximately pure submodule of an R-module, if for each ideal I of R.

Limiting Performance of the Ejector Refrigeration Cycle with Pure Working Fluids

open access: yesEntropy, 2023
An ejector refrigeration system is a promising heat-driven refrigeration technology for energy consumption. The ideal cycle of an ejector refrigeration cycle (ERC) is a compound cycle with an inverse Carnot cycle driven by a Carnot cycle. The coefficient
