This paper describes the application of reinforcement learning (RL) to the di cult real world problem of elevator dispatching. The elevator domain poses a combination of challenges not seen in most RL research to date. Elevator systems operate in continuous state spaces and in continuous time as discrete event dynamic systems. Their states are not fully observable and they are nonstationary due...

Cohen, D., and R. G. Wanner (Division of Safety, NIH, Bethesda, MD 20205). The case of the intoxicated cells—an epldemlologic note. Am J Epidemiol 1981;113:250-3. An episode is described In which tissue culture In a laboratory could have become Intoxicated due to the reclrculation of toxic exhaust fumes extruded from the roof of a research Institution. A route of entry was found whereby a porti...

The paper introduces a genetic algorithms based elevator group control system utilising new approaches to multiobjective optimisation in a dynamically changing process control environment. The problem of controlling a group of elevators as well as the basic principles of the existing single-objective genetic elevator group control method are described. The foundations of the developed multi-obj...

Blood samples submitted to the Civil Aeromedical Institute (CAMI) from aviation accident fatalities are analyzed for carbon monoxide (CO), as carboxyhemoglobin (COHb), and hydrogen cyanide, as cyanide (CN(-)). These analyses are performed to establish possible exposure of victims to smoke from in-flight/post-crash fires or to CO from faulty exhaust/heating systems. The presence of both gases in...

In this research paper an attempt has been made to integrate the programmable logic controller (PLC) with elevator for developing its control system. Thus, this paper describes the application of programmable logic controller for elevator control system. The PLC used for this project is GE FANUC with six inputs and four outputs. The programming language used is ladder diagram.

OBJECTIVE To compare the risk of accidents in patients with uncontrolled seizures, in seizure-free patients, and in patients with chronic headache. METHOD This was a prospective longitudinal case-controlled study with interviews. A semi-structured questionnaire was used in the epilepsy and headache outpatient clinics of the Hospital das Clínicas of UNICAMP. RESULTS Group I was composed of 4...

Introduction: Nearly half of occupational accidents in Iran occur in construction sites. Therefore, modeling of occupational accidents in these sites is one of the solutions to design safety strategies to reduce occupational accidents in the field of construction. This study was designed and conducted with the aim of modeling the cause-consequence of accidents in construction sites. Material a...

purpose: to evaluate the clinical manifestations and surgical results in patients with double elevator palsy operated at labbafinejad eye center from 1993 to 2004. methods: the study was conduct on hospital records of 20 patients with double elevator palsy. patients were classified in three groups including primary elevator muscle palsy (9 subjects), primary supranuclear palsy with secondary in...

AIMS To assess seasonal, weekday, and public holiday effects on alcohol-related road accidents and drinking diaries among young Swiss men. METHODS Federal road accident data (35,485 accidents) from Switzerland and drinking diary data from a large cohort of young Swiss men (11,930 subjects) were analysed for temporal effects by calendar week, weekday and public holiday (Christmas, New Years, N...
