We present and analyze a minimalist model for the vertical transport of people in tall building by elevators. focus on start-of-day operation which arrive at ground floor fixed rate. When an elevator arrives floor, passengers enter until capacity is reached, then they are transported to their destination floors. determine distribution times that each person waits arrives, number waiting elevato...

We introduce a novel group elevator scheduler based on an explicit decision-theoretic calculation for the expectation of any polynomial function of passengers’ waiting times, marginalized over sources of uncertainty in the system state. The same framework can be used to identify risky assignments that have low expected costs but may cause some individuals to be ”stranded” with excessive waits f...

The ability for an autonomous robot to track and identify multiple humans and understand their intentions is crucial for socialized human-robot interactions in dynamic environments (Michalowski and Simmons 2006). Take CoBot (Rosenthal, Biswas, and Veloso 2010) trying to enter an elevator as an example. When the elevator door opens, suppose there are multiple humans occupied, CoBot needs to trac...

Accurate control of grip force during object manipulation is necessary to prevent the object from slipping, especially to compensate for the action of gravitational and inertial forces resulting from hand/object motion. The goal of the current study was to assess whether the control of grip force was influenced by visually induced self-motion (i.e., vection), which would normally be accompanied...

In this paper; a hybrid model of a multiple elevator system is proposed, consisting of a color-timed transition Petri net (CTTPN) model and a set of control rules implemented via the so-called control places in the CTTPN model. The Petri net model is a highly modulized structure, whose constituent modules can be classiJed into four types: Call Management Module, Louding/Unloading Module, Basic ...

Nowadays, the increasing use of group elevator control systems owing to increasing building heights makes the development of high-performance algorithms necessary in terms of time and energy saving. Although there are many studies in the literature about this topic, they are still not effective enough because they are not able to evaluate all features of system. In this paper, a new approach of...

The number of elevator facilities with laboratories to test shelled corn for aflatoxin on site is increasing. The inherent difficulty in accurately determining the true aflatoxin concentration of a lot of corn may have serious implications. Deviations from the true value are of even greater significance at busy locations where a high throughput is desired. This study was instituted to measure (...

OBJECTIVE If bowels and other structures are in the pathway of high-intensity focused ultrasound (HIFU) beam during magnetic resonance image-guided HIFU (MRgFUS) therapy, filling to the bladder and the rectum and then emptying the bladder (i.e., the BRB technique) is used to avoid them. A modified BRB technique might be useful method to using a uterine elevator method or by inducing uterus down...

BACKGROUND The zygoma is the most prominent portion of the face. Almost all simple zygomatic arch fractures are treated in a closed fashion with a Dingman elevator. However, the open approach should be considered for unstable zygomatic arch fractures. The coronal approach for a zygomatic arch fracture has complications. In this study, we introduce our method to reduce a special type of unstable...
