in the present paper, an analysis was carried out to investigate effects of radiation on a free convection flow bounded by a vertical surface embedded in a porous medium with constant suction velocity. it was under the influence of uniform magnetic field in the presence of a homogenous chemical reaction and viscous dissipation with constant heat and mass flux. the non-dimensional governing equa...

Simulation of free surface flow and sudden wave profile are recognized as the most challenging problem in computational hydraulics. Several Eulerian/Lagrangian approaches and models can be implemented for simulating such phenomena in which the smoothed particle hydrodynamics method (SPH) is categorized as a proper candidate. The incompressible SPH (ISPH) method hires a precise incompressible hy...

This paper proposes a "non-contact virtual clay modeling interface." We developed a prototype of a three-dimensional modeling system that allows the designer to deform the "virtual clay" by his or her hand movements. In our proposing method, the user's hand movement is observed using multiple cameras to estimate its position and orientation. The virtual clay is modeled by Catmull-Clark subdivis...
