In this work, the 3D geometry of patient specific aorta was utilized to carry out CFD studies on the effect of different valve opening (45°,62.5° and fully opening) on the hemodynamic properties. The result shows that the lower valve opening induced jet flow and hampered the flow on the additional carotid arteries. Besides, the leaflets were subjected to extreme stress values having disastrous consequences...
This paper investigates the different empirical propagation models for the next mobile generation known as the Long Term Evolution - Advanced (LTE-A) in the 2GHz band‥ The effects of the propagation models are analyzed in urban, suburban and rural environments by using Monte-Carlo statistical methodology. The Joint Task Group 5–6 (JTG5-6) propagation model is discussed in the paper along with the...
This paper describes the evaluation of the spreading factor inertia weight Particle Swarm Optimization (PSO) for the fuzzy logic control (FLC) of FES-assisted paraplegic indoor rowing exercise (FES-rowing). The FES-rowing is introduced as a total body exercise for rehabilitation of lower extremities through the application of functional electrical stimulation (FES). FLC is used to control the knee...
In a journal bearing application, viscosity is a key property of the lubricant that affects bearing performance. Viscosity of the lubricant controls the film thickness established during an operation. In the present work, an ultrasonic method has been used to measure the viscosity profile around an operating journal bearing. The reflection coefficient profile around the journal was established. A...
