In this paper, we model the statistical properties of imaging exam durations using parametric probability distributions such as the Gaussian, Gamma, Weibull, lognormal, and log-logistic. We establish that in a majority of radiology procedures, the un

This study is concerned with the determination of an optimal appointment schedule in an outpatient-inpatient hospital system where the inpatient exams can be cancelled based on certain rules while the outpatient exams cannot be cancelled. Stochastic

In this paper, we study the problem of maintaining the connectivity of a Wireless Sensor Network (WSN) using decentralised topology control protocols. Previous algorithms on topology control require the knowledge of the density of nodes (λ) in the s
