If different materials have the same thermal conductivity, the material with the lowest heat capacity will get to a steady-state condition faster, and that material will have the highest thermal

diffusivity. Thermal

diffusivity as such produces no thermal resistance for steady-state temperatures.

All of the test images corrupted by speckle noise are filtered using

diffusivity functions of Perona Malik, Charbonnier, and Weickert.

(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.

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.

C is an instrumental factor, f is the frequency of light modulated, k is the thermal conductivity, [alpha] is thermal

diffusivity, [l.sub.i] is the thickness of the layer i, [[sigma].sub.j] is the complex TWs diffusion coefficient [[sigma].sub.j] = (1 + i)[a.sub.j] a is the reciprocal of the thermal diffusion length [mu], a = 1/[mu], and [mu] = [([alpha]/[pi]f).sup.1/2].

To further investigate the effects of HTP process on the properties of MG, the thermal

diffusivity of MG with and without HTP was measured at various temperatures.

Finally, the thermal

diffusivity can be calculated from (5).

The

diffusivity [D.sub.2A] of [H.sub.2A] dimer is known [10, 14, 15] to be 2 x [10.sup.-13] [cm.sup.2]/s at 150[degrees]C (for the deuterium isotope).

The effective permeability K, the effective

diffusivity parameters [D.sub.b] as well as [D.sub.n] are assumed to be symmetric, continuous and uniformly positive definite with respect to [theta] within every interval [mathematical expression not reproducible].
