Implementation of the pending event set (PES) is often crucial to the execution speed of a simulation. Parallel access implementation of the PES is a possible means of gaining performance improvement in discrete event simulation. In this paper a comparative study of some sequential and parallel access implementations of the PES is presented, these include linked lists, the Calendar Queue, the L...

purpose: to investigate the levels of klotho and endothelin-1(et-1) in plasma and aqueous humor in patients with pseudoexfoliation syndrome (pes). methods: fifteen individuals with pes and 15 age-matched subjects without pes who were scheduled for cataract extraction participated in the study. samples of aqueous humor and peripheral blood were taken in the operating room just before cataract su...

an innovative method based on the membrane bioreactor (mbr) technology was developed as a potential remedy for the water shortage. mbrs attracted much attention in the field of wastewater treatment and reuse. it is reported from many researchers that membrane bioreactor technology is feasible and an efficient method for the treatment of wastewater. however, mbrs are faced to membrane fouling whic...
