There are many power electronic converters and motor drives connected together to form the electrical system of an elevator. In this paper, we have presented a modeling tool that has the advantages of utilizing capabilities of the PMSM software in detailed simulations of converters, motor drives, and electric machines. In addition, equivalent electrical models of Elevator drive system. This pap...

This Paper attempts to give some guidance on the question, of how best to approximate to an aircraft with an asymmetric elevator control for the purpose of flutter calculations. Two examples of asymmetric controls that are.common in practice are (1) the design case of a partitioned elevator each part having its own separate power unit and with one such unit having failed, and (2) the asymmetric...

In many past fires, not a few people used elevators for their evacuation, although they are told to escape by stairs in emergency. Also, it is expected that the number of people who have difficulty to use stairs in evacuation would become larger, since the proportion of aged people in the total population has been rapidly increasing recently and also accessibility of disabled people has been im...

Although numerous studies have reported the physiological strain associated with firefighting, cardiac responses during a large-scale fire operation have not been reported and cardiac responses have not been compared based on crew assignment. The aims of this study were (1) to characterize cardiac strain during simulated high-rise firefighting, and (2) to compare the cardiac strain associated w...

In this paper, we formulate the elevator dispatching problem as a stochastic bilevel optimization problem, where a group of elevators serves a set of transportation requests. In the upper level, the requests are assigned to the elevators. In the lower level, the route for each elevator is solved separately. The lower level problem predicts the optimal system state for a finite planning horizon ...

U radu su opisane konstrukcijske izvedbe dizala s protuutegom te i odstojnom užnicom. Dan je pregled osnovnih komponenti dizala, kao njihov princip rada njihova uloga u podizanju ljudi i/ili tereta. Izveden proračun za zadane ulazne vrijednosti: električni pogon, nosivost kabine - 750 kg (10 osoba), visina dizanja 15 m, broj stanica 6, brzina vožnje 1 m/s. Izvršeni proračuni pogonskog mehanizma...

In the paper I argue that "falling elevator" model once proposed by Dean Zimmerman to improve some drawbacks of Peter van Inwagen's account how a belief in Christian resurrection could be made compatible with materialist understanding human persons is not satisfactory. requires only survival, but also true death person, while falling elevator can merely provide us an material person able miracu...

JGP study suggests the anion exchanger AE1 operates via an elevator-like mechanism.
