Wavelet-Based Adaptive Anisotropic Diffusion Filter

(2015) evaluated the whole baru almond drying kinetics and obtained diffusivity values from 18.15 x [10.sup.-11] to 37.08 x [10.sup.-11] [m.sup.2] [s.sup.-1] for the temperatures of 50, 60 and 70 [degrees]C, showing that the diffusivity values also increased when the drying temperature increased.

where [D.sub.eff] is the effective moisture diffusivity ([m.sup.2]/s); [D.sub.cal] is the estimate moisture diffusivity ([m.sup.2]/s); r is the volume equivalent radius of GB seeds, with 0.769 x [10.sup.-2] m as its value; a is the scale parameter of Weibull distribution; [R.sub.g] is the physical dimension constant.

Artificial Neural Network Modeling of Drying Kinetics and Color Changes of Ginkgo Biloba Seeds during Microwave Drying Process

In this paper, we present an original experimental procedure for the study of the gas permeation process which permits accurate evaluation of the gas diffusivity (and permeability) of thin polymer films and processes characterized by short transient times: this often occurs in the permeation of small-size penetrants and in high-temperature processes.
