Similar like in (3) computing yxi in (5), when p=q (i.e., prime), can be done using the modulus yxi=(∑l=1d−1 al il+b)mod q. Otherwise the additions and multiplications in the expression for yxi are defined by the operations in the finite field. To illustrate the use of...

The storage modulus at 5% shear strain increases from 10.55 Pa for NDDF to 30.13 Pa, 42.2 Pa and 48.9 Pa for 0.5, 0.8 and 1 wt% ZrO2 NP NDDF, respectively. This indicates that the elasticity component of NDDF is enhanced due to the addition of ZrO2 NPs. Besides, NDDF behaves as ...
Furthermore, parameters for the deformation modulus, primarily used in simulations of ground deformation associated with hydrate production, are challenging to obtain owing to a lack of proposed datasets. In this study, pressure cores were recovered in the same area in which the second offshore ...
Permeability–porosity correlation: In some cases, a semi-log cross plot of permeability versus porosity provides a good correlation (Section 7.3.3). The correlation can be used to predict permeability based on well log porosity. Average permeability and vertical and lateral permeability variation can...
A multiple-scattering-based scheme has been intro- duced to study the effective medium properties of metamaterials with anisotropic lattices and isotropic scatterers30,31, yielding a scalar bulk modulus and tensorial mass density at finite frequencies in the long-wavelength regime. There exist other ...
