The homogenized energy framework quantifying ferroelectric and ferromagnetic hysteresis is increasingly used for comprehensive material characterization and model-based control design. For operating regimes in which thermal relaxation mechanisms and stress-dependencies are negligible, existing algorithms are sufficiently efficient to permit device optimization and the potential for real-time co...

— Using the two-scale convergence method we study the homogenized behaviour of the warping and the torsion problems, in a two-dimensional domain with a quasi-periodic perforation, as we II as the relationship between the two homogenized problems. The Neumann problem is also analized.

A two day meeting hosted by the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC) was held in May 2006 in Entebbe, Uganda to review the laboratory performance of virologic molecular methods, particularly the Roche Amplicor DNA PCR version 1.5 assay, in the diagnosis of HIV-1 infection in infants. The meeting was attended by approximately 60 participan...

Recently, consumers have become more concerned with foods contain natural ingredients in terms of health and economic. Hence, in this study the effect of concentrate of smoked and sun dried raisin at 3 levels (1, 3 and 5%) as a natural humectant to improve the quality and shelf life of flat bread were investigated. Results showed that addition of smoked and sun dried raisin improved quality and...

When the wavelength is much larger than the typical scale of the microstructure in a material, it is possible to de£ne effective or homogenized material coef£cients. Two numerical methods for the determination of the homogenized, coef£cients are compared. Numerical examples, where extreme properties of the effective material are achieved in the two dimensional case, are presented.

In this study, a 3-dimensional (3D) implementation of representative volume element homogenization using bond-based peridynamic formulation is presented. Periodic boundary condition established by coupling the displacements of periodic point pairs. Homogenized (effective) material properties are obtained based on displacement gradient tensor. The current approach is val...

background and objectives: nasal polyposis is a diseases resulting from complex pathogenetic mechanisms. some studies showed that tgfβ1 had significant role in this pathogenesis. in this study, we investigated the roe of cytokines and mediators in polyp development. material and methods: in this case- control study, healthy nasal mucosal samples were obtained from 24 people undergoing septoplas...

The simulation of optical resonance filters based on quarter-wave shifted waveguide gratings is described. Wavelet-based numerical homogenization is applied to the filters, and the properties of the homogenized operators and their solutions are investigated. A method is proposed for replicating periodical sub-structures in the homogenized operators, making it possible to model very large struct...
