A Two-time-scale Phenomenon in a Fragmentation-coagulation Process
Consider two urns, A and B, where initially A contains a large number n of balls and B is empty. At each step, with equal probability, either we pick a ball at random in A and place it in B, or vice-versa (provided of course that A, or B, is not empty). The number of balls in B after n steps is of order n√, and this number remains essentially the same after n√ further steps. Observe that each b...
متن کاملOn time dynamics of coagulation-fragmentation processes
We establish a characterization of coagulation-fragmentation processes, such that the induced birth and death processes depicting the total number of groups at time t ≥ 0 are time homogeneous. Based on this, we provide a characterization of mean-field Gibbs coagulationfragmentation models, which extends the one derived by Hendriks et al. As a byproduct of our results, the class of solvable mode...
متن کاملMonitoring Lognormal Reliability Data in a Two-Stage Process Using Accelerated Failure Time Model
The reliability data is getting used to monitor and improve the quality of products or services. Nowadays, most of products or services are the results of processes with dependent stages referred to as multi-stage process. In these processes, the quality characteristics are affected by the quality characteristics in the previous stages, called as cascade property. In some cases, it is not possi...
