Zirconium dioxide, commonly known as zirconia, is an interesting material and is receiving growing attention due to its excellent mechanical properties. The solid was characterized for surface area measurements, scanning electron microscopy (SEM), Energy dispersive X-ray diffractometry (EDX) and potentiometric titrations. Surface titrations were carried out at the temperature range 303 to 323K ...

Furthermore this orthogonalisation can be used to improve computational effeciency when comparing a large number of models with the same X0. Define x ′ = (In − P 0)x (which can be precomputed) and then assuming that X0Xγ = 0a×b, we have x T (In − P 0 − P γ)x = x′T (In − P γ)x. This reduces the number of computations that have to be performed for each model matrix Xγ . When the only parameter co...

avo as a known methodology is used to identify fluid type and reservoir lithology in subsurface exploration. method discussed in this paper, consists of three stages, including: direct modeling, inverse modeling and cross plot interpretation. by direct modeling we can clarify lithology or fluid dependent attributes. analysis performed using both p-p and p-sv attributes. inverse modeling deals w...

Figure 3 three orthogonal slices of partial brain field maps (a) before and (b) after filtering. For correct background field removal it was necessary to pad the FOV by a factor of 2.5, 2.5 and 6 in the x, y and z directions respectively. The calculation of the background was performed on a matrix of resolution 3x3x1.5mm. The parameters of this specific filtering were t=0.3, n=20 Figure 2 Field...
