analysis of non-laminar flows in coarse alluvial beds has a wide range of applications in various civil engineering, oil and gas, and geology problems. darcy equation is not valid to analyze transient and turbulent flows, so non-linear equations should be applied. non-linear equations are classified into power and binomial equations. binomial equation is more accurate in a wide range of velocit...

Studies have shown that videoconferences are an effective medium for facilitating communication between parties who are separated by distance. Furthermore, studies reveal that videoconferences are effective when used for distance learning, particularly when learners are engaged in complex collaborative learning tasks. However, as in face-to-face communication, learners benefit most when they re...

We chronicle the use of acknowledgements in twentieth century scholarship by analyzing and classifying more than 4,500 specimens covering a 100-year period. Our results show that the intensity of acknowledgment varies by discipline, reflecting differences in prevailing socio-cognitive structures and work practices. We demonstrate that the acknowledgment has gradually established itself as a con...

A common form of embodied social engagement involves acting as an ensemble, with all participants aware of each other and mutually engaged. In this naturalistic comparative study, we term this kind of triadic socio-cognitive activity ‘fluid collaboration’. Fluid collaboration occurs when participants establish the pace of ensemble activity mutually, with their moves flexibly adjusted and respon...
