A Two-Stage Model Queueing with No Waiting Line between Channels [PDF]

open access: yesMathematical Problems in Engineering, 2013
We consider a new queuing model with sequential two stations (stages), single server at each station, where no queue is allowed at station 2 and with no restriction at station 1. There is a FCFS service discipline in which the input stream is Poisson having rate . The service time of any customer at server () is exponential with parameter .

Scaling and data collapse for the mean exit time of asset prices [PDF]

open access: yes, 2005
We study theoretical and empirical aspects of the mean exit time of financial time series. The theoretical modeling is done within the framework of continuous time random walk. We empirically verify that the mean exit time follows a quadratic scaling law
