We present a physically-based animation method for simulating the diffusion of water pollutant in this paper. Our method allows animating the dynamic evolution of biological pollutants (e.g., water hyacinth, algae) on largescale water surface effectively. To enable the simulation of such a phenomenon in large scale virtual environment, we simplify the problem by considering the water pollutants...

Concrete-epoxy interface can be found in many strengthened or retrofitted structures, especially in Hong Kong where concrete structures are the majority. In practice, epoxy is usually used in repairing concrete structures because of its excellent adhesion, chemical and heat resistance, good mechanical properties and electrical insulating properties. The bond between concrete and epoxy has been ...

The present investigation deals  with the reflection and transmission phenomenon due to incident plane longitudinal wave at a plane interface between inviscid fluid half-space and a thermoelastic diffusion solid half-space with dual-phase-lag heat transfer (DPLT) and dual-phase-lag diffusion (DPLD) models. The theory of thermoelasticity with dual-phase-lag heat transfer developed by Roychoudhar...

In this article, we study superconvergence properties of immersed finite element methods for the one dimensional elliptic interface problem. Due to low global regularity of the solution, classical superconvergence phenomenon for finite element methods disappears unless the discontinuity of the coefficient is resolved by partition. We show that immersed finite element solutions inherit all desir...

After designing and constructing a coalescence cell, drop/interface coalescence phenomenon was studied in the absence and presence of single surfactant.Two surface active agents of sodium dodecyl sulfate and 1-decanol were used. Distilled water was used as dispersed phase. Toluene, n-heptane and aqueous 60% (v/v) of glycerol were selected as continuous phases, separately. It was found that ...

A fully instrumented ring-on-ring galling test has been developed based on the ASTM G196 principle. Torque records allow computation of coefficient friction and other tribological parameters to capture wear behavior interface. Contact electrical resistance is also recorded helping detect onset in contact. solid lubricant anti-galling solution OCTG connections involving a coated versus steel int...

due to the positive and negative impacts and implications of new technologies (internet and satellite), as a new phenomenon in human society this study examines the role of new communication technologies, especially in a family torn apart by divorce phenomenon (legally and emotionally) in iranian families and especially this city has done. a survey of all families living in this city, which in ...

Zinc coating is formed by the heterogeneous assembly of the Γ, Γ1, δ, ζ and η phases whose mechanical properties greatly differ from each other. Thermal strains resulting from large differences between thermal expansion coefficients are partially relaxed by the formation of a crack network. In order to model this phenomenon, initial hardness, thermal expansion coefficient αi and toughness (KIC)...
