Seismic Performance of Rail-Counterweight System of Elevator in Buildings
Elevators serve a critical function in essential facilities such as hospitals and need to remain operational during and after earthquakes. However, they are still known to malfunction during earthquakes even after several design and sensing improvements required by the current code have been …

From Grain Elevator to Creamery: Reconnecting to the Working Landscape in Silvana, Washington
… proposes the conversion of an obsolete grain elevator in the agricultural community of Silvana, Washington, into a small-scale artisan creamery. As the grain elevator is located directly in the working landscape where the cows are raised and the milk is produced, a strong connection between …

Design and Control of A Ropeless Elevator with Linear Switched Reluctance Motor Drive Actuation Systems
… transportation applications such as a linear elevator. A one-tenth scaled prototype elevator focused on a home elevator with LSRMs is designed and extensive experimental correlation is presented for the first time. The proposed LSRM has twin stators and a set of translator poles without …

Modelling and Prediction of the Effects of Dynamic Responses of Tall Buildings on an Elevator System
… on a high rise building often influence all elevator components and affect the ride quality of the elevator car. The lateral and longitudinal vibrations of the suspension and compensating ropes can occur and the lateral and longitudinal vibrations at the elevator car may take place. The ropes …

The No.5 terminal grain elevator in the Port of Montreal : monument in a shifting landscape
The No. 5 terminal elevator in the port of Montreal is the last of a group of colossal machines for moving and storing grain that once lined the waterfront in front of Old Montreal. The terminal elevators of the port of Montreal were the culmination-point of the national infrastructures of grain …

The Steep Climb to Low Earth Orbit: A History of the Space Elevator Community's Battle Against the Rocket Paradigm
This thesis examines the growth of the space elevator community in America from 1975 to 2010. It argues that the continued practical failures of the space elevator, a proposed technology for efficiently transporting payloads and people into space without conventional propulsion sources, resulted …

A Wireless Call Button Network Design
Traditional call button networks that control elevator systems utilize a wired connection for communication. The communication cables are run through the elevator shaft from one call button to another and finally to the controller on the roof. Installing this wired link is highly time consuming. In …

Limit Cycle PIO Analysis With Simultaneously Acting Multiple Asymmetric Saturation
… including stick position limiting, elevator deflection limiting, and elevator rate limiting. These analyses involve the use of dual input describing functions which enable the prediction of frequency, amplitude, and mean point of oscillation.

The impacts of grain subterminals on rural highways
… each production zone in an impact region to each elevator, allocates the flows among truck-types, computes the annual trips, gross vehicle weights and axle weights, and assigns the truck trips to the highway network. A set of highway models was also formulated which computes the equivalent single …

Elevators and escalators: the study of an innovative approach to teaching fingerboard geography to heterogeneous string classes
… Instruction involved the use of the terms elevators and escalators to teach chromatic finger patterns on one string and between all strings. The participants (N=57) in the study were beginning string students enrolled in three middle school classes in Austin, Texas. Students were divided …

Hi-Low : new semi public space in the high-rise
… four units, connected by weird mirror-surrounded elevators and emergency stairs. Small and narrow corridors cannot really offer any proper space for social interaction. Let's talk more about the inside of an apartment housing complex. First of all, even though there is trash in front of the …

The directional stability and control of an airplane during the landing roll
… influence can be reduced by using the elevator, or the horizontal tail, to keep the nosewheel lightly loaded during the landing roll. Because of the inherent instability of a tricycle landing gear, some type of control is needed to keep the aircraft on the runway during the landing …
