Objectives: This study determined whether naturally-occurring, but significantly different, outpatient follow-up frequencies are associated with clinical outcomes and service waiting times. Study Design: Longitudinal retrospective study. Methods: …
In the absence of randomized controlled and natural experiments, it is necessary to balance the distributions of (observable) covariates of the treated and control groups in order to obtain an unbiased estimate of a causal effect of interest; …
We consider the problem of an operator controlling a fleet of electric vehicles for use in a ride-hailing service. The operator, seeking to maximize profit, must assign vehicles to requests as they arise as well as recharge and reposition vehicles in …
Digitalization has been a concern for both practitioners and researchers for several years. It obviously applies to the field of supply chain management, where information flow management plays a major role. In Quebec (Canada), the digitalization of …
This paper presents a decomposition approach for solving a variant of the routing and wavelength assignment (RWA) problem, in which all connection requests are covered by geodesics, i.e., shortest paths with respect to the number of hops. Our …
Assessing the performance of electrical impedance tomography (EIT) systems usually requires a phantom for validation, calibration, or comparison purposes. This paper describes a resistive mesh phantom to assess the performance of EIT systems while …
