Research Paper Heat and Mass Transfer
Free convective heat and mass transfer of magnetic bio-convective flow caused by a rotating cone and plate in the presence of nonlinear thermal radiation and cross diffusion

M. Gnaneswara Reddy; Sandeep N

Volume 7, Issue 1 , August 2017, Pages 1-21


  This article explores the heat and mass transfer behaviour of magnetohydrodynamic free convective flow past a permeable vertical rotating cone and a plate filled with gyrotactic microorganisms in the presence of nonlinear thermal radiation, thermo diffusion and diffusion thermo effects. We presented ...  Read More

Research Paper Control
Optimizing control motion of a human arm With PSO-PID controller

Mohammad Hossein Bayati Chaleshtari; Elahe Norouzi; Habib Ahmadi

Volume 7, Issue 1 , August 2017, Pages 23-34


  Functional electrical stimulation (FES) is the most commonly used system for restoring function after spinal cord injury (SCI). In this study, we used a model consists of a joint, two links with one degree of freedom, and two muscles as flexor and extensor of the joint, which simulated in MATLAB using ...  Read More
