An algorithm is presented for transit passenger OD estimation. The algorithm, like some other existing OD estimation techniques, generates estimates based upon passenger boarding and alighting counts at each stop along the route. The algorithm is distinct in that it does not only estimate an OD matrix for the vehicle trip from which the boarding and alighting counts were taken. Rather, it furth...

Future 4D aircraft trajectories demand comprehensive consideration of environmental, economic, and operational constraints, as well as reliable prediction of all aircraft-related processes. Mutual interdependencies between airports result in system-wide, far-reaching effects in the air traffic network (reactionary delays). To comply with airline/airport challenges over the day of operations, a ...

The main goal of this paper is to document the nature of boarding schools and empirically analyze the difference of nutrition intake and malnutrition status between boarding and non-boarding students in western rural China. By using two data sets about boarding schools and boarding students in Shaanxi Province, a representative province in western rural China, this paper finds that dormitory an...

The problem of finding an optimal back-to-front airplane boarding policy is explored, using a mathematical model that is related to the 1+1 polynuclear growth model with concave boundary conditions and to causal sets in gravity. We study all airplane configurations and boarding group sizes. Optimal boarding policies for various airplane configurations are presented. Detailed calculations are pr...

Time is crucial in the airlines industry. Among all factors contributing to an aircraft turnaround time; passenger boarding delays is the most challenging one. Airlines do not have control over the behavior of passengers; thus, focusing their effort on reducing passenger boarding time through implementing efficient boarding strategies. In this work, we attempt to use cellular Discrete-Event Sys...

Objective. The boarding of patients in Emergency Department (ED) hallways when no inpatient beds are available is a major cause of ED crowding. One solution is to board admitted patients in an inpatient rather than ED hallway. We surveyed patients to determine their preference and correlated their responses to real-time National Emergency Department Overcrowding Score (NEDOCS). Methods. This wa...

Sufism is always seen for having more emphasis on the salvation hereafter. It also has become a spiritual force in human souls to adapt changing times. However, ulama pesantren Riyad al-Jannah Islamic Traditional Boarding School, Pacet, Mojokerto understand it differently as they see sufism and entrepreneurship which focuses economic betterment can join hand.

A hospital Emergency Department’s (ED’s) wait times can be driven by high occupancy in its downstream InPatient hospital (IP). ED patients not admitted to the IP due to high IP occupancy or transfer delays are termed to be 'boarding' in the ED. ED boarding causes a decrease in ED service capacity, longer ED wait times, increased fractions of patients that leave without treatment, and increased ...

background: the employees of welfare centers, due to the special conditions of their work, may be exposed to excessive occupational stress and workload . thus, the aim of this study was to determine the effect of workload and occupational stress on the general health of female employees of public welfare centers.   materials and methods: this was a correlational research on 63 female employees ...
