Multiplicity and oscillations in a model for catalyzed oxidation of carbon monoxide
(American Institute of Physics Publising LLC, 1994)
We extend a model proposed for explaining multiplicity and oscillations of concentrations and temperature in catalyzed oxidation of carbon monoxide; the importance of the dimension of the system and the closure approximation ...

A constant magnetocaloric response in FeMoCuB amorphous alloys with different FeB ratios
(AIP Publishing, 2007-05-04)
The magnetocaloric effect of Fe91−xMo8Cu1Bx (x = 15 , 17 , 20) amorphous alloys has been studied. The temperature of the peak of magnetic entropy change can be tuned by altering the Fe / B ratio in pk pk the alloy, without ...

Cellular automaton model for the simulation of laser dynamics
(American Physical Society, 2003)
The classical modeling approach for laser study relies on the differential equations. In this paper, a cellular automaton model is proposed as an alternative for the simulation of population dynamics. Even though the model ...
