چکیده
Using the equation of continuity and equations for the atomic flux we develop the finitedifference-scheme program DIMES-C to calculate concentration profiles and layer thickness’ in multiphase binary systems after diffusion annealing. In this way we can calculate problems with arbitrary initial concentration distributions, concentration dependent interdiffusion coefficients, and general phase diagram data. The capabilities of our calculation were introduced and demonstrated at the binary silver-zinc-system which shows a transition from linear to parabolic growth.

متن کاملCellular Automata Simulation of a Bistable Reaction-Diffusion System: Microscopic and Macroscopic Approaches
The Cellular Automata method has been used to simulate the pattern formation of the Schlögl model as a bistable Reaction-Diffusion System. Both microscopic and macroscopic Cellular Automata approaches have been considered and two different methods for obtaining the probabilities in the microscopic approach have been mentioned. The results show the tendency of the system towards the more sta...
متن کاملComparative study of computer simulation softwares
One of the methods for analyzing systems is simulation. Network simulation is a technique that models the behavior of the network by performing transaction calculations between different network entities and using mathematical formulas and taking observations from network products. A network simulator is a piece of software or hardware that predicts the behavior of a computer network without a ...
متن کاملOutput Consensus Control of Nonlinear Non-minimum Phase Multi-agent Systems Using Output Redefinition Method
This paper concerns the problem of output consensus in nonlinear non-minimum phase systems. The main contribution of the paper is to guarantee achieving consensus in the presence of unstable zero dynamics. To achieve this goal, an output redefinition method is proposed. The new outputs of agents are functions of original outputs and internal states and defined such that the dynamics of agents a...
