Real-time algorithms for the bilevel double-deck elevator dispatching problem
Double-deck elevators consist of two elevator cars attached together and, thus, save building core space. In the destination control system (DCS), passengers register their destination floors in the elevator lobbies.

Modal and Dynamic Analysis of a Tether for a Nonequatorial Space Elevator
To study the fundamental dynamics of the nonequatorial space elevator, a universal modeling strategy is presented, which applies to any anchored latitude. The equations of motion are established on the basis of the lumped mass model of the tether coupled
