The distance from a given position toward one or more destinations, exits, and way points is a more or less important input variable in most models of pedestrian dynamics. Except for the special case when there are no obstacles in a concave scenario – i.e. each position is visible from any other – the calculation of these distances is a nontrivial task. This isn’t that big a problem, as long as...

We consider a clinical trial with a survival outcome, in which subjects may switch in a non-randomised manner from their randomised treatment to control treatment during follow-up. We extend a method for binary outcomes, due to Sommer and Zeger, by viewing a survival outcome as a sequence of binary outcomes. This leads to a simple expression for the hazard ratio among non-switchers at each time...

The presence of moral hazard in the banking sector can have worrying results. This paper examines the role of government guarantees to banks in generating moral hazard in Iran. We test for moral hazard among bank creditors by determining whether protected banks received more funds from creditors than non-protected banks. Empirically, to determine the existence of moral hazard among bank manag...

Changes in demographics and the burgeoning costs of medical care are putting hospitals in all developed countries under increased pressure. This paper will demonstrate how simulation is contributing to satisfying stakeholders demands for increased efficiency and rates of return as well as improving the potential for geriatric patients reconvalescence and reducing the number of ‘corridor beds’. ...

There has not been a significant decline in fatalities, injuries and illnesses in the construction industry despite rigorous efforts of safety professionals and strong governmental enforcement of safety laws. Inappropriate work planning; insufficient communication between workers and supervisors; and lack of safety training are some of the key contributing factors. The utilization of BIM techno...

Mobile crowdsourcing networks (MCNs) are a promising method of data collecting and processing by leveraging the mobile devices’ sensing and computing capabilities. However, because of the selfish characteristics of the service provider (SP) and mobile users (MUs), crowdsourcing participants only aim to maximize their own benefits. This paper investigates the incentive mechanism between the abov...

PP-plots for survival distributions are considered where one survival distribution is plotted against the other. This is seen as another way of visualizing the nature of the relationship between the two survival distributions along with typical Kaplan-Meier plots. For three survival distributions, the PPP-plot is introduced where the survival distributions are plotted against each other in thre...

Distributed generation is a form of electric power privatization. Consumers install their own power station to supply the local loads and/or share in the utility loads. Many protective problems have been developed due to the existence of these distributed generations. However, a protective strategy should be developed to protect the system and the generator itself from different hazards. One pr...

We study simulation of gate circuits in the infinite algebra of transients recently introduced by Brzozowski and Ésik. A transient is a word consisting of alternating 0s and 1s; it represents a changing signal. In the algebra of transients, gates process transients instead of 0s and 1s. Simulation in this algebra is capable of counting signal changes and detecting hazards. We study two simulati...
