An experimental and numerical study of free convection heat transfer from a channel consisting of a vertical sinusoidal wavy surface and a vertical flat plate has been carried out. The vertical wavy surface was maintained at a constant temperature, while the flat plate is adiabatic. A Mach-Zehnder Interferometer was used to determine the local heat transfer coefficients of sinusoidal wavy surfa...

Learners of all ages face complex decisions about how to study effectively. Here we investigated three such decisions made in concert—time allocation, ordering, and spacing. First, college students were presented with, and made judgments of learning about, 16 word-synonym pairs. Then, when presented with all 16 pairs, they created their own study schedule by choosing when and how long to study ...
