Control charts are widely applied in industrial practice to maintain manufacturing processes in desired operating conditions. Design of control charts aims at finding the best parameters for the operation of chart. In recent years, it has been revealed that the control charts operating with VSI (variable sampling interval) schemes give better performance than with FSI (fixed sampling interval) ...

An Archival Repository reliably stores digital objects for long periods of time (decades or centuries). The archival nature of the system requires new techniques for storing, indexing, and replicating digital objects. In this paper we discuss the specialized indexing needs of a write-once archive. We also present a reliability algorithm for effectively replicating sets of related objects. We de...
