Abstract: | The moment analysis is applied to perform large scale
simulations of the rice-pile model. We find that this model shows
different scaling behavior depending on the driving mechanism
used. With the noisy driving, the rice-pile model violates the
finite-size scaling hypothesis, whereas, with fixed driving,
it shows well defined avalanche exponents and displays good finite
size scaling behavior for the avalanche size and time duration
distributions. |
