An Internet of Things Approach for Intelligent Monitoring of Conveyor Belt Rollers

This article presents an Internet of Things (IoT) architecture suitable for large scale sensor networks for condition monitoring. The developed technology has been applied and demonstrated for rotating conveyor belt rolls. Wireless sensor networks is a relatively new and emerging technology, not only capable of addressing a large number of applications in industry but is also applicable for hom...

Measurements of Shallow Water Breaking Wave Rollers

Large scale laboratory experiments concerning breaking wave propagation over a fixed-bed, barred beach were performed. The primary observations of interest were video intensity time series obtained from a set of high-resolution video cameras in order to study the onset of wave breaking in shallow water and wave roller transformation in the surf zone. The approach is new in the sense that the an...

Short-Term and Long-Term Impacts of Pre-Service vs. In-Service Reflective Task-Oriented Training on Novice and Experienced Teachers’ Mediating Roles

Teacher training programs in EFL contexts pursue the goal of promoting teaching skills and critical dispositions in prospective and experienced teachers and their ability to reflect on and enhance their mediating roles to maximize learning outcomes. Yet, discrepancies in teachers’ roles during and after the programs are not uncommon and accentuate the need to assess outcomes. This quasi-experim...

Emergent vortices in populations of colloidal rollers.

Coherent vortical motion has been reported in a wide variety of populations including living organisms (bacteria, fishes, human crowds) and synthetic active matter (shaken grains, mixtures of biopolymers), yet a unified description of the formation and structure of this pattern remains lacking. Here we report the self-organization of motile colloids into a macroscopic steadily rotating vortex. ...
