Among people living with HIV (PLHIV) on antiretroviral therapy (ART), it is important to determine how quality of life (QOL) may be improved and HIV-related stigma can lessened over time. This study assessed the effect peer support QOL internal during first year after initiating ART among a cohort PLHIV in north-eastern Vietnam. A sub-sample randomised controlled trial was implemented between October 2008 November 2010 Quang Ninh, In intervention group, participants (n = 119) received...
This paper presents a novel equilibrium formulation, that uses the cell-based smoothed method and conic programming, for limit shakedown analysis of structures. The virtual strains are computed using straining smoothing technique based on elements discretized mesh. Fictitious elastic stresses also determined within framework finite element (CS-FEM)-based Galerkin procedure, equations residual satisfied in an average sense at every cell. All constrains imposed only one point domains, instead...
This study proposes a pseudo-lower bound method for direct limit analysis of two-dimensional structures and safety evaluation based on isogeometric integrated through Bézier extraction. The key idea in this approach is that the stress field separated into two parts: fictitious elastic residual, then equilibrium conditions are recast by weak form. Being different from displacement which employs kinematic formulation, approximations satisfy automatically volumetric locking phenomena. Dealing...
This paper presents a numerical procedure for lower bound limit analysis of plane problems governed by von Mises yield criterion. The stress fields are calculated based on the Airy function which is approximated using moving least squares technique. With use Airy-based equilibrium mesh-free method, equations ensured to be automatically satisfied priori, and size resulting optimization problem reduced significantly. Various strain with arbitrary geometries boundary conditions examined...
This study introduces a novel numerical procedure for conducting shakedown analysis on structures subjected to cyclic loads. The determination of safety load multipliers is achieved through the integration edgebased smoothed finite element method (ESFEM) and conic programming. By applying smoothing technique, all constraints are satisfied in an average manner within domains, as opposed at numerous Gauss points Finite Element Method (FEM). approach results reduction problem size number...
