Powder X-ray diffraction (XRD) data were collected on a Bruker D8 Advance Diffractometer equipped with monochromatic Cu Ka radiation.
The reduction behaviour and the interaction of catalysts components were studied by Temperature programmed reduction (TPR) using TPDRO1100 MS equipped with thermal conductivity detector.
Interaction of catalysts particles was investigated by Temperature programme reduction.
Reduction peak at 360°C is due to the reduction of CuO to Cu as given in equation 2 (2) TPR peak at 380 is due to the reduction of ZrO2 [10].
The TPR profile revealed reduction temperature of 200-300 °C.

Cold rolling with 70% of reduction introduced strain, utilized for re-crystallization during
annealing at different temperatures.
Their process was applied to thin strip, 2 mm thick, using hot reductions of approximately 40% to yield a product approximately 1.2 mm thick.
The plates were then cold rolled to a reduction of about 70%, with a final thickness of approximately 1mm.
The EBSD data of 2V and 4V steels after annealing at 650C is presented in Fig. 8, showing similar behaviour of changes in LAGB and HAGB spacings with annealing times.
EBSD data clearly demonstrated the recovery process by the measurements of HAGB and LAGB spacings.

Apparent activation energy data obtained from linear regression equation
As it was displayed, the apparent activation energy decreased by 5.6 kJ mol-1 for the catalyst in which the support Al2O3 was precoated by 5 wt% MgO, comparing to that of NA catalyst.
Pore structure and surface area data of different samples It was observed that there were MgAl2O4 spinel species over the MgO precoated catalysts.
X-ray diffraction profiles of catalysts 3.3 Temperature Reduction Analysis (H2-TPR) There were three reduction peaks for all the catalysts according to the TPR profiles of different catalysts.
The reduction peaks should be ascribed to the reduction of different nickel species.
Temperature and the percentage of reduction peak area data obtained from H2-TPR diagrams It was exhibited in Table 3 that the percentage of the peak β increased as the introduction of small amount of MgO, and then decreased when the amount of MgO loading increased while the percentage of high temperature peak was also increased.

Material data were defined by means of tensile tests and extrapolation to higher deformation.
The obtained EBSD data were analysed by HKL Channel 5 software.
Table 1 Basic input data to the model of drawing.
The MUD value above unity indicates that there are more data points of a particular orientation than would be expected from a sample that is totally random.
Obtained data served as a valuable basis for the optimization of technological processes in production.

These give a corresponding size reduction of ten times compared to conventional dielectrics, silicon nitride (Si3N4).
We propose MgZnO thin film as a new dielectric material in MMIC design to achieve size reduction over currently-used materials.
From S11 data, the properties of MgZnO film such as relative permittivity, capacitance and loss tangent were extracted.
From S11 data others RF properties such as dielectric constant, capacitance and loss tangent can be extracted as summarized in Table 1.
Size reduction of capacitor area approximately ten times over the MMIC materials has been obtained.

Metodology
The first stage of this research is carried out by collecting the required fundamental data and literature used as the design basis references.
Therefore, a reduction in the temperature of overhead gas from the stabilizer column causes a reduction in the temperature of the feed stream to the LP/MP compressors package.
Thus, the reduction of the feed stream’s temperature to the LP/MP compressors package causes a reduction in the total electrical load requirement (reduction from 823 kW to 730 kW).
Therefore, a reduction in the temperature of overhead gas from the stabilizer column causes a reduction in the temperature of the feed stream to the LP/MP compressors package.
Thus, the reduction of the feed stream’s temperature to the LP/MP compressors package causes a reduction in the total electrical load requirement (reduction from 1035 kW to 760 kW).

The RVM is used to learn the feature data and implement the classification work when new measured data are available.
Then the latter is used as input data for training the RVMs.
To obtain the highest separation rate for the test data sets, the best parameters are established for each SVM using the validation data.
Four conclusions can be drawn from the study. (1) The wavelet packet node energies of the structural vibration signal are useful as the damage feature and are easy to obtain. (2) Dimension reduction is necessary for the feature data, and the NMF technique can be used for dimension reduction.

Then, the measured data
are aligned to the CAD model.
As the measured data completely describe the object, cross sections may be created at any position and compared to the nominal data.
The measuring data can be directly loaded into CAM systems like TEBIS or WorkNC as STL data (polygon mesh).
Milling on measurement data.
For simply copying a tool or a modified area, the digitized data may also be imported as STL data into CAM systems without surface reconstruction.
