Machine Vision Instrument to Measure Spray Droplet Sizes

Developing an instrument to measure effective factors on clinical learning

Introduction: Although nursing students spend a large partof their learning period in the clinical environment, clinicallearning has not been perceived by its nature yet. To develop aninstrument to measure effective factors on clinical learning innursing students.Methods: This is a mixed methods study performed in 2 steps.First, the researchers defined “clinical learning” in nursingstudents thr...

The development of an instrument to measure quality of vision: the Quality of Vision (QoV) questionnaire.

PURPOSE To develop an instrument to measure subjective quality of vision: the Quality of Vision (QoV) questionnaire. METHODS A 30-item instrument was designed with 10 symptoms rated in each of three scales (frequency, severity, and bothersome). The QoV was completed by 900 subjects in groups of spectacle wearers, contact lens wearers, and those having had laser refractive surgery, intraocular...

Dynamic Droplet Sizes for Drift Fluxes

OVERVIEW There are many two-fluid mixtures of practical interest. For example, mixtures of air and water or oil and water occur frequently in environmental and industrial processes. The existing modeling capability in FLOW-3D for mixtures of two fluids is the DRIFT routine that computes the relative motion of the two components arising from buoyancy and viscous forces. This model works quite we...
