On the well-posedness problem of the electrorheological fluid equations
Boundary Value Problems, 2018 A kind of electrorheological fluid equations, with the orientated convection terms ut=div(a(x)|∇u|p(x)−2∇u)+b→(x)⋅∇uq,(x,t)∈Ω×(0,T), $$u_{t} =\operatorname{div}\bigl(a(x)|\nabla u|^{p(x)-2}\nabla u \bigr)+\vec {b}(x)\cdot\nabla u^{q},\quad (x,t)\in\Omega\

Une note sur le coefficient oméga (ω) et ses déclinaisons pour estimer la fidélité des scores
Mesure et Évaluation en Éducation, 2020 Au cours des dernières décennies, certains auteurs ont suggéré de rejeter le coefficient alpha (α) de Cronbach (1951) pour adopter le coefficient oméga (ω) de McDonald (1985, 1999) basé sur un modèle d’analyse factorielle.

Don’t Forget the Model in Your Model-based Reliability Coefficients: A Reply to McNeish (2018)
Collabra: Psychology, 2019 McNeish (2018) advocates that researchers abandon coefficient alpha in favor of alternative reliability measures, such as the 1-factor reliability (coefficient omega), a total reliability coefficient based on an exploratory bifactor solution (“Revelle’s ...

Testing different decoupling coefficients with measurements and models of contrasting canopies and soil water conditions [PDF]
Annales Geophysicae, 2008 Four different approaches for the calculation of the well established decoupling coefficient Ω are compared using measurements at three experimental sites (Tharandt – spruce forest, Grillenburg and Melpitz – grass) and simulations from the soil ...

Aerodynamic Characteristics of a Tumbling Plate under Free Flight
Journal of Fluid Science and Technology, 2009 In this study, we deal with the tumbling, which is a rotating motion with the axis perpendicular to the falling direction. Our purpose is to reveal the fundamental aerodynamic characteristics of the tumbling, experimentally.
