ventricular fibrillation is the cause of the most sudden deaths. the recent findings have clearly proved the correlation between the slope of restitution curve with ventricular fibrillation. cellular automata is a powerful tool for simulating complex phenomena in a simple language. in this paper, a simple model is proposed for the simulation of the property of restitution in a single cardiac ce...

To enhance agility and quick responding to customers' demand, manufacturing processes are rearrenged according to different systems. The efficient execution of a manufacturing system depends on various factors. Among them, cell design and human issue are the pivotal ones. The proposed model designs cellular manufacturing systems using three objective functions from three different perspectives,...

The biodegradation kinetics of 4-chlorophenol (4-CP) and phenol microbial growth Pseudomonas putida (P. putida) cells were estimated in batch biofilm reactors. kinetic parameters on determined using the Haldane formula. maximum specific rate P. phenol, half-saturation constant self-inhibition 0.512 h−1, 78.38 mg/L 228.5 mg/L, respectively. yield (YP) was 0.618 mg phenol/mg cell. experimental re...

This paper presents the modeling and simulation of a proton exchange membrane fuel cell (PEMFC) generation system for off-grid and on-grid operation and configuration. A fuel cell DG system consists of a fuel cell power plant, a DC/DC converter and a DC/AC inverter. The dynamic model for fuel cell array and its power electronic interfacing are presented also a multi-input single output (MISO) D...
