The shorter queue polling model
We consider a two-queue polling model in which customers upon arrival join the shorter of two queues. Customers arrive according to a Poisson process and the service times in both queues are independent and identically distributed random variables having the exponential distribution. The two-dimensional process of the numbers of customers at the queue where the server is and at the other queue is a two-dimensional Markov process. We derive its equilibrium distribution using two methodologies: the compensation approach and a reduction to a boundary value problem
Laparoscopic cholecystectomy and appendicectomy in situs inversus totalis: A case report and review of literature
Situs nversus totalis is a rare condition which presents difficulty in clinical diagnosis as well as laparoscopic surgery for cholelithiasis. The mirror image anatomy makes the laparoscopic intervention difficult even for an experienced surgeon. Presenting here is a case report and review of literature
