Routing of two elevators

There are many approaches to model an elevator routing system. In this paper, I shortly describe some literature, wherein different manners to model the routing system are presented. A simulation approach, dynamic programming and polling systems are used to model the routing system. In the simulation approach zoning is often used. Zoning means that the floors are split into a number of zones, e...

Operating molecular elevators.

Inspired by the concept of multivalency in living systems, two mechanically interlocked molecules have been conceived that incorporate not once or twice but thrice the features of a pH-switchable [2]rotaxane with two orthogonal recognition sites for dibenzo[24]crown-8 (DB24C8), and 2,3-dinaphtho[24]crown-8 (DN24C8)-one a dialkylammonium ion (CH(2)NH(2)(+)CH(2)) and the other a bipyridinium dica...
