We present a constraint programming formulation for the elevator trip origin-destination matrix estimation problem, and propose different approaches to solve the problem. An elevator trip consists of successive stops in one direction of travel with passengers inside the elevator. It can be defined as a directed network, where the nodes correspond to the stops on the trip, and the arcs to the po...

PURPOSE To describe the clinical manifestations of subtypes of double elevator palsy and to report the outcomes of surgery in these patients. METHODS This retrospective study was conducted on hospital records of patients with double elevator palsy at Labbafinejad Medical Center over a ten-year period from 1994 to 2004. Patients were classified into three subgroups of primary elevator muscle p...

Elevator is an important transport medium in multi-storage building. With the development of better architecture technology, buildings are raising in height. Hence an elevator becomes an important medium of vertical transportation. There are several advantages of an elevator in the modern world. Hence more importance is given to the design of an elevator control system, which is easy for the ma...

Abstract The elevator brake is an important part to ensure the safe operation of elevator, and its performance directly determines safety whole machine. This paper describes a test scheme principle, makes reliability through device for brake, recording suction release voltage, response time, surface temperature delay time mechanical parts on both sides after specific number action. analysis cha...

The goal of this project was to design the vision system onboard a PR2 robot tasked with navigating between floors in the ICICS X-Wing at UBC. The vision task includes the detection and localization of elevator buttons that must be pressed in order to ride the elevator to a desired floor. The system is implemented in ROS, the Robotic Operating System from Willow Garage, and executed on the PR2....

Elevator traffic demand forecasting is the essential prerequisite for effectively implementing elevator group control system (EGCS). Considering that there exists lots of abnomal information in elevator traffic caused by subjectivity and occasionality in human behaviour and that observing traffic information continuously is costly and difficult, an improved grey forecasting based method using m...

Background and study aims: Endoscopic retrograde cholangiopancreatography-related infections are of increasing global concern due to the emergence of multidrug-resistant bacteria such as carbapenem-resistant enterobacteriaceae (CRE), with bacterial biofilm production postulated as one cause of persistent infection from such virulent organisms. Because N-acetylcysteine (NAC) has been shown to po...

Neuromuscular changes were studied by electromyography in rhesus monkeys which adapted to nasal obstruction for 2 years and then in the succeeding year recovered to nasal respiration. Obstructing the nasal passage with silicone plugs induced specific behavioral responses which remained for the duration of nasal obstruction and were lost within 8 days after removal of the plugs. Animals demonstr...

We present a constraint programming formulation for the elevator trip origin-destination matrix estimation problem using a lexicographic bi-criteria optimization method where least squares minimization is applied to the measured counts and the minimum information or the maximum entropy approach to the whole matrix. An elevator trip consists of successive stops in one direction of travel with pa...

With the advancement of intelligent computerised buildings in recent years, there has been strong demands for intelligent elevator control with more sophistication and diverse functions. The design criteria of an intelligent elevator control system would include optimising the movement of a group of elevators with respect to time, energy, load, etc. In this paper, a new elevator group superviso...
