a shortcut procedure as quick, easy-to use method for design and simulation of multicomponent batch distillation is used to predict the operating condition of recovering xylene from solvent in an existing batch distillation column in benzol refinery. the procedure can be used to investigate the effect of the operating parameters on the operation of column for three possible modes of batch disti...

In a structured system graphically represented, the satisfaction of structural properties depends on graphical conditions. Among these conditions, we choose to study one of the most commonly used conditions, the so-called connectivity condition. The validity of this condition depends on the validity of some edges in the system graphical representation. The corresponding edges reflect the operat...

In this paper, we study robustness properties of transportation networks with respect to its pre-disturbance equilibrium operating condition and the agents’ response to the disturbance. We perform the analysis within a dynamical system framework over a directed acyclic graph between a single origin-destination pair. The dynamical system is composed of ordinary differential equations (ODEs), one...

A new design on the electrostatic discharge (ESD) protection scheme for CMOS IC operating in power-down-mode condition is proposed. By adding a VDD_ESD bus line and diodes, the new proposed ESD protection scheme can block the leakage current from I/O pin to VDD power line to avoid malfunction during power-down-mode operating condition. During normal circuit operating condition, the new proposed...

Induction machines play a important role in industry and there is a demand for their reliable and safe operation. Different failures occurs in induction machines gives excessive down times and generate large losses in term, and this motivates the condition monitoring of induction motors. The condition monitoring includes taking measurements on three phase induction motor when it is operating in...

Sammanfattning For every operating condition of an internal combustion engine there exists an optimal spark timing, called maximum brake torque (MBT), which maximises the output torque and the efficiency of the engine. Traditionally MBT timing is implemented as an open-loop control where the ignition timing is found by using a combination of static lookup tables and sensor information. With a d...
