A method for enumerating sets of concurrent events handles single-shot events and recurring events. A processor receives a message sent to a user operating a client device, analyzes the message in light of previously identified patterns and scores assigned to scanned messages, determines a future message that should be received by the client device based on the received message, and transmits an item of information based on the determined future message. Data stored on the VoIP terminal device is assessable via a standard interface for facilitating data access only after the VoIP terminal device has been successfully logged into the private network. Statistics are aggregated across the testing population and presented not just as data, but with recommended actions backed up by analysis. Further, a method for depositing a deposition material layer on a substrate using an edge exclusion mask is described. The first adsorptive separation zone delivers a raffinate stream to a raffinate distillation zone and an extract stream to an extract distillation zone.
