The dissipation factor and electric conductivity of the composites are found to slightly increase with the filler loading, and to still remain at rather low levels owing to the insulating alumina shell as an interlayer barrier between the core Al, which prevent the direct contact between core Al, and suppresses and inhibit the loss and leakage.

The same as [1], the test results of the water content, acidity content, BDV, dissipation factor (DF), DCG, and 2-Furfuraldehyde content are taken as the input data for the proposed HI calculation method in this section.
Wave energy dissipation factor above roughness elements (in the presence of vegetation), [f.sub.c] or the wave friction factors, [f.sub.w] at the bed are usually a function of the wave orbital amplitude and the hydraulic roughness, r (Nielsen 1992; Soulsby 1997).
Key measures of performance are the dielectric constant (Dk), which quantifies signal range, and the dielectric dissipation factor (Df), which indicates signal loss.
