conclusions using the simulation as a decision making tool helps us to decide how we can reduce outpatient's waiting time. comparison of outputs of this scenario and the based- case scenario in simulation model shows that combining physician's work time changing with patient's admission time changing (scenario 9) would reduce patient waiting time about 73.09%. due to dynamic and complex nature ...

This work presents a simulation approach to the design and economic evaluation of fuel oil hydrotreating processes for the control of SO2 and NOx emission in an Iranian steam power plant. The percent of fuel oil desulphurization was estimated from the SO2 emissions standards for power plants. Based on two different scenarios according to (I) European and (II) Iranian standards, the design and s...

Please refer to the paper, “Darwin’s World Simulation in C#: An Interpreter” from the January/February, 2010 issue of JOT. This paper focuses on the GUI aspects of the implementation. The two remaining classes are World (the model of the Darwin world) and the GUI class WorldUI. The World classs communicates to the WorldUI class, the observer class, by firing events. This model/view separation p...

Ptolemy is a flexible and extensible platform for simulations, rapid prototyping, and other software systems. It is our third generation software environment, building on our experience with Blosim, a signal processing simulation system, and Gabriel, a prototyping environment for real-time signal processing. Unlike its predecessors, Ptolemy does not enforce a single simulation or execution mode...

the karkheh dam reservoir with a capacity of more than 5 billion cubic meter is the largest dam in iran with both agricultural and drinking usages. its hydrodynamics and water quality were modeled and simulated to analyze the total maximum daily load (tmdl) of total dissolved solids (tds). the simulation was supported with measurements of temperature and tds measurements during two years. a lat...

This paper investigates the robust decentralized nonlinear control of power flow in a power system using a new configuration of UPFC. This structure comprises two shunt converters and one series capacitor called as hybrid power flow controller (HPFC). A controller is designed via control Lyapunov function (CLF) and adaptive observer to surmount the problems of stability such as tracking desired...

The manufacturing operations often involve multistage processes where the process capability of each stage is affected by the process capability of its precedent processes. This property is known as the cascade property. The purpose of this paper is to estimate the process capability of the second stage of two-stage process while the cascade property impact is removed using residuals analysis. ...
