five-zone simulating moving bed (smb) system, designed for ternary separation, is a modified form of standard four-zone smb which is only effective in binary separation. it was reported in literature that the five-zone smb separates the extract-ii stream with a lower purity value than that of raffinate and extract-i streams. to address this issue, five zone smb was designed, using safety margin...

Application programmers increasingly prefer distributed stor-age systems with strong consistency and distributed transac-tions (e.g., Google’s Spanner) for their strong guarantees andease of use. Unfortunately, existing transactional storage sys-tems are expensive to use – in part because they require costlyreplication protocols, like Paxos, for fault tolerance. In thisp...

in advance longwall mining, the safety of mine network, production rate, and consequently, economic conditions of a mine are dependent on the stability conditions of gate roadways. the gate roadway stability is a function of two important factors: 1) characteristics of the excavation damaged zone (edz) above the gate roadway and 2) loading effect due to the caving zone (cz) above the longwall w...
