Abstract The objective of this study was to assess the effects small, incremental additions wheelchair frame mass (0 kg, +2 and +4 kg) on mechanical propulsion characteristics in both straight curvilinear maneuvers. A robotic system used propel a manual over smooth tiled surface following rectilinear (“Straight”) (“Slalom”) trajectories. Three unique loading conditions were tested. Propulsion c...

Cost-effectiveness information on where malaria rapid diagnostic tests (RDTs) should be introduced is limited. We developed incremental cost-effectiveness analyses with data from rural health facilities in Ghana with and without microscopy. In the latter, where diagnosis had been presumptive, the introduction of RDTs increased the proportion of patients who were correctly treated in relation to...

OBJECTIVE To compare the incremental cost and effects (averted admission) of using a metered-dose inhaler (MDI) against wet nebulization to deliver bronchodilators for the treatment of mild to moderately severe asthma in pediatric emergency departments (EDs). METHODS We measured the incremental cost-effectiveness from the perspective of the hospital, by creating a model using outcome characte...

While incremental propagation for global constraints is recognized to be important, little research has been devoted to how propagator-centered constraint programming systems should support incremental propagation. This paper introduces advisors as a simple and efficient, yet widely applicable method for supporting incremental propagation in a propagator-centered setting. The paper presents how...
