The plane-wave cut-off energy of 500 eV was employed, and Brillouin zone (BZ) sampling was performed with a uniform 20×20×20 Monkhorst-Pack k-point grid due to the high sensibility of the conductivity to the number of k-points.
In addition, the longer the relaxation time, the lower the scattering by phonon, impurity and grain boundary, and the better the conductivity.

The use of organic waste (groundnut shell ash) management for soil stabilization is significant and offers the ecology a number of advantages.
This substance comprises amorphous silica, a sign of cementing qualities that, in the event of poor soil, might generate strong between soil grains.

The tests were stopped after 3E+06 cycles, and the specimens not broken after this number of cycles were considered run-out.
The XRD measurements allowed to obtain also the full width of diffraction peak at half (FWHM), a parameter index of hardening, grain distortion and dislocation density [9].

For pretreatment process, the silicon substrate was scratched with a diamond powder of 1µm grain size in alcohol by ultrasonic cleaning machine.
The quadratic model of Y can be written as following, ∑ ∑∑∑ = − = < = = + ++= k i iii j k i iij k ji j k i ii XbXXb XbbY 1 2 1 1 2 1 0 (1) where Y is the desired response (experimental results), b0 is constant, k is the number of independent variables (four in this paper: substrate temperature (T), microwave power (W), pressure (P) and H2 concentration (H)), bi, bii and bij represent the coefficients of linear, quadratic and cross product terms, respectively.

This study considers the grain primary silicon morphology changing process and eutectic modification process with electromagnetic vibration.
It has been well documented that the transformation of unmodified flakes to modified fibrous structures arises from a very different type of growth of the Si phase and this difference appears to lie in the number of twins found in unmodified and modified Si.

A high number of privately dug wells may lead to groundwater depletion.
However, subsurface rock formations that correspond to the interpretation of surface geology still exist, and based on their physical properties, rocks with smaller grain sizes have higher bulk densities and lower porosities, resulting in higher water content [10].

Because preparation of sorbent is the foundational part of the test and key technology for evaluating and investigating desulfurization sorbent properties, there are a number of sorbent manufacturing techniques, including spry drying, impregnation, crushing and screening, and granulation[10].
Using different theoretical models, such as those of the grain model with variable properties, to fit the kinetic results obtained in thermobalance, it was shown that the sulfidation rate of Zinc ferrites was controlled by gas diffusion across the sulfide layer just formed and by the intrinsic reactivity of the sorbent[11].

But when more than one response comes under consideration and the system is subjected to a number of constraints it is very difficult to tackle the problem.
Taguchi method is very popular as it requires a well balanced experimental design (limited number of experiments) which saves time as well as cost.
SiO2 + TiO2= 30% CaO + MgO= 10% Al2O3 + MnO= 45% CaF2= 15% Grain Size = 0.25 - 2.00 mm Basicity Index = 0.6 Welding has been performed on the SAW setup [Make: ADOR WELDING LIMITED, INDIA] Model- MAESTRO 1200(F).
This approach converts correlated responses into an equal or less number of uncorrelated quality indices which are called individual principal components.
(a) (Lower-the-Better) criteria: (4) Here, (b) HB (Higher-the-Better) (5) Here, Assuming, the number of experimental runs in Taguchi’s OA design is, and the number of quality characteristics is.

The web and the lower flange of arched corrugated metal roof have a number of transverse corrugations, which are distributed along the extension direction with pitch arcs, with lengthways equably distributed along the arch.

The equation that clearly depicts the relationship between all gamma radiographic parameters, namely specifications of source (i.e. energy and activity), specifications of specimen (i.e. thickness and linear atomic attenuation coefficient) and radiography conditions (i.e. source-to-film distance, film type and scattering) is: where D is the film density of radiograph (dimensionless), E is the film exposure (Ci.min), SFD is source-to-film distance, and e is Euler number (2.718) and t is beam path thickness (mm).
