Low-Memory and Interactive-Rate Animation of Water-Column Based Flows

Simultaneous Ash and Sulphur Removal from Bitumen Using Column Flotation Technique: Experiments, RSM Modeling and Optimization

An efficient method was employed for the ash and pyrite sulphur removal from bitumen using column flotation process. The bitumen samples containing 9.6% sulphur (6.81% in the pyrite sulphur form) and 26.4% ash were successfully showed up to 75.20% of pyrite sulphur (e.g.; 51.66% of total sulphur) and 70.81% of ash removal. The Box-Behnken Design (BBD) was employed to design the experiments, to ...

Interactive-Rate Animation Generation by Parallel Progressive Ray-Tracing on Distributed-Memory Machines

DYNAMICAL SIMULATION OF UNDERWATER SOUND PROPAGATION IN THE HORMOZ STRAIT

Providing an illustration of sound propagation in the Hormoz Strait ,this paper is about acoustic wave propagation in shallow water for a harmonic point source with low frequency, less than 1000 and solution of a homogenous Helmholtz equation using parabolic equation. C++ programming is used to solve Helmholtz equation [9] and MATLAB software is used to illustrate figures and animate them [6], ...

Numerical Simulation of Granular Column Collapses with Pressure-Dependent Viscoplastic Model using the Smoothed Particle Hydrodynamic Method

This paper presents a numerical analysis of granular column collapse phenomenon using a two-dimensional smoothed particle hydrodynamics model and a local constitutive law proposed by Jop et al. This constitutive law, which is based on the viscoplastic behaviour of dense granular material flows, is characterized by an apparent viscosity depending both on the local strain rate and the local press...

The Study of Education Based on Animation in Patient’s Performance under Hemodialysis in Emergency Evacuation Selected Hospitals of Aja

Introduction: A disaster evacuation program is one of the most important parts of hospital crisis management. The following study was carried out to determine the effects of animation-based teaching on hemodialysis patients’ performance in an emergency evacuation. Material and Method: In this quasi-experimental study, two out of four AJA Hospitals in Tehran that had hemodialysis wards, were sel...
