The elevator group control systems are the control systems that manage systematically, three or more elevators in order to efficiently transport the passengers. In the elevator group control system, the area-weight which determines the load biases of elevators is a control parameter closely related to the system performance. This correspondence proposes a fuzzy model based method to determine t...

This work aims at the design of a roped elevator prototype, which uses a linear induction motor (LIM) as a traction machine. It is also concerned with the development of a specific inverter to feed the linear motor that allows several ways to drive the elevator through a suitable choice of the RMS voltage levels, angular phase displacement and electrical frequency of the output voltage. The res...

Abstract. Accurate traffic data are the basis for group control of elevators and its performance evaluation by trace driven simulation. The present practice estimates a time series of inter-floor passenger traffic based on commonly available elevator sensor data. The method demands that the sensor data be transformed into sets of passenger input-output data which are consistent in the sense tha...

Purpose. Although stair use in workplaces can provide an accessible means of integrating physical activity into work routines, there is little information available on how building design influences stair use. Design. This cross-sectional study assessed the relationship between stair use and the design and location of stairs. Setting. Ten threeor four-story academic buildings on two university ...

We propose a method for tracking multiple pedestrians using a binary sensor network. In our proposed method, sensor nodes are composed of pairs of binary sensors and placed at specific points, referred to as gates, where pedestrians temporarily change their movement characteristics, such as doors, stairs, and elevators, to detect pedestrian arrival and departure events. Tracking pedestrians in ...

OBJECTIVE To assess the informational, educational and instrumental environments among Mexican healthcare settings for their potential to promote physical activity (PA). MATERIALS AND METHODS The Environmental Physical Activity Assessment Tool for Healthcare Settings (EPATHS) was developed to assess the PA environments of 40 clinics/hospitals representing the three Mexican healthcare systems ...

One of the major impediments in using computer simulation to model and optimize construction processes has been the fact that decision makers often do not have the training nor the time to check the validity of simulation models prepared by others and thus have little confidence in the results. Animation is an increasingly popular technique that can be used to verify, debug and validate simulat...
