Dynamics and critical behavior of the q model

The investigation of critical behavior and dynamics of the q model was presented. The q model was introduced through its application to stress flow through granular matter at rest. The critical point of the q model was analyzed by imagination that a uniform load had been applied to the top of the granular medium and evolution with fluctuations depth was studied in the distribution of load. It was found that evolution of load showed scaling behaviour. The circumstances under which quantum network models could be mapped onto the classical q model were also discussed.
