Introduction The input parameters of a structure, like geometry, material parameters and loading, are expected to vary.
Both material, νF, geometrical, νG, and model, νM, uncertainties could be evaluated through the use of appropriate coefficients
(4) Schlune’s and Cervenka’s methods differ in evaluating the coefficient of variation (COV) of the materials.

Such models allowed for the development of many materials that are used in electromagnetism for antennas and dielectrics.
In a similar manner, the mathematical formulation of diffusion by Fick facilitated the development of membranes and diffusion-barrier high performance materials.
Synthetic polymers (plastics) are one such material.
To continue, another mathematical technique used in imaging is the inverse conductivity problem, also known as EIT (Electrical Impedence Tomography), having applications in medical imaging, underground prospection and non-destructive testing of materials.

Materials of activated carbon (AC) were used as sorbents in FGD [2, 3] for high stability, large surface area, abundant micro-porous structure and surface oxide species.
Apart from calcium-based [6, 7] and carbon materials sorbents, supported oxide metals oxides such as Fe [8], Cu [9-10] and V [11] for catalytic oxidation SO2 into SO3 have attracted more and more interests of researchers and engineers, since desulfurization and regeneration reactions readily occur.

Shearing patterns of AZ31 Mg Alloy processed by equal-channel angular pressing via various route Xiao-ming Feng1, a, Tao-tao Ai1, b 1Department of Materials Science and Engineering, Shanxi University of Technology, Hanzhong 723003, China afxmhz@126.com, baitaotao0116@126.com Keywords: Equal-Channel Angular Pressing, AZ31 Mg alloy, grain refinement Abstract.
It is well known that materials with ultrafine-grain have excellent mechanical properties.
Reduction of the mean grain size is expected to increase the yield strength and also the ultimate tensile strength at room temperature and to promote superplastic deformation at higher strain rates and/or lower temperatures than those conventionaly used for large grain size materials.
Equal-Channel Angular Pressing (ECAP) is now an accepted processing technique for the development of an ultrafine-grained (UFG) structure in bulk materials.

There are several types of materials used in RRAM, such as perovskite-type oxides [1, 3, 5], binary metal oxides [2-4, 6], organic compounds [7, 8], amorphous Si [9], and solid-state electrolytes [4].
Among the RRAM materials being studied, binary metal oxides are most favorable because of their simple constituents, compatible with CMOS processes, and resistive to thermal/chemical damages [2, 4, 6, 10].
