This article proposes a characterization of the double reed in quasistatic regimes. The nonlinear relation between the pressure drop, deltap, in the double reed and the volume flow crossing it, q, is measured for slow variations of these variables. The volume flow is determined from the pressure drop in a diaphragm replacing the instrument's bore. Measurements are compared to other experimental...

In this paper, the heat transfer to the fluid, passing through the double forward facing step (FFS) channel with square obstacle is enhanced by Taguchi’s S/N ratio analysis. Flow through the forward facing step channel has a wide range of applications in thermal systems due to its flow separation and subsequent reattachment, which in turn enhances the heat transfer. Flow separation and reattach...

Microexpressions are fast and spatially small facial expressions that difficult to detect. Therefore, motion magnification techniques, which aim at amplifying hence revealing subtle in videos, appear useful for handling such expressions. There basically two main approaches, namely, via Eulerian or Lagrangian techniques. While the first one magnifies implicitly by operating directly on image pix...
