Abstract In this paper, mixed formulations are presented in the framework of isogeometric Reissner–Mindlin plates and shells with aim alleviating membrane shear locking. The based on Hellinger-Reissner functional use stress resultants as additional unknowns, which have to be interpolated appropriate approximation spaces. unknowns can eliminated by static condensation. analysis condensation is p...

introduction: the purpose of this study was to evaluate the sealing ability of 3 obturation techniques in oval-shaped canals by bacterial leakage assessment. methods: sixty mandibular incisors with oval canals were selected after providing buccolingual and mesiodistal radiographs. the teeth were sectioned at a 10 mm distance from the apex. after instrumentation, the teeth were divided into 3 gr...

We study gaugino condensation in the context of superstring effective theories using the linear multiplet formulation for the dilaton superfield. Including nonperturbative corrections to the Kähler potential for the dilaton may naturally achieve dilaton stabilization, with supersymmetry breaking and gaugino condensation; these three issues are interrelated in a very simple way. In a toy model w...

The method for the evaluation of the distribution of carbon nanotube sizes from the static adsorption measurements and computer simulation of nitrogen at 77 K is developed. We obtain the condensation/evaporation pressure as a function of pore size of a cylindrical carbon tube using Gauge Cell Monte Carlo Simulation (Gauge Cell MC). To obtain the analytical form of the relationships mentioned ab...

We propose a new approach for the simulation of conjugate heat exchangers. First, we introduce a dimensionality-reduced mathematical model for conjugate (fluid-solid) heat transfer: in the fluid channels, we consider a mixed-mean temperature defined on one-dimensional filaments; in the solid we consider a detailed partial differential equation conduction representation. We then propose a Petrov...

The role of latent heating from individual cloud processes associated with one part of a springtime extratropical cyclone, the warm front, is assessed using highresolution modelling. Condensation and cloud droplet nucleation are the largest sources of latent heat along the frontal surface and together produce rates of horizontal frontogenesis that are of the same order of magnitude as the defor...

Motivated by the ghost condensate model, we study the Randall-Sundrum (RS) brane-world with an arbitrary function of the higher derivative kinetic terms, P(X), where X = −(∂φ)2. The five-dimensional Einstein equations reduce to two equations of motion with a constraint between P(X) and the five-dimensional cosmological constant on the brane. For a static extra dimension, P(X) has solutions of t...

We are studying the efficient solution of system linear equations stemming from mass conserving stress-yielding (MCS) discretization Stokes equations. perform static condensation to arrive at a for pressure and velocity unknowns. An auxiliary space preconditioner positive definite block makes use scalable solvers conforming Finite Element spaces low order is analyzed with emphasis placed on rob...
