Although the networks have many types, they consist of a large number of neurons that are widely interconnected to constitute a parallel processing network.
Each layer includes a number of neurons and is sequentially connected.
As long as the number of neurons and the training samples are enough, the “black box” is able to predict the output for any input.
The network was trained by dynamical adjustment method to determine the node number of the hidden layer.

In this type of the forming, the material is strengthened and a texture is formed, which means that grains are elongated in the direction of the applied force.
Total number of elements for the whole assembly was just over 250,000 pieces.
The number of steps in the second operation was 200 with the write interval of each 10. step and the step increment was 0.5 mm/step.
The number of steps, the write interval, and the increment are the same as in the second operation, but the calculation stops when the distance between the dies reaches 10.5 mm. 10.
In Fig. 6 can be seen the temperature field of the first operation for the step number 1.

According to [19], the required numbers of discontinuities to be mapped are 20 for orientation of the set, 50 – 100 for characterization.
The maximum declination of the mean plane of the discontinuity was measured with the clinometer (dip) and expressed in degrees as a two digit number from (000-900) e.g 030 or 880 (c) The azimuth of the dip (dip direction) was measured in degrees counted clockwise from the true North and expressed as a three digit number e.g. 0350 or 2870 (0000-3600) (d) The dip and dip direction were recorded in this order with two digit and three digit numbers separated by a line e.g. 880/2870.
The pair of numbers represents the dip vector.
(f) A total number of 115 readings were taken as specified by [18] i.e (50-300 readings) and 50 readingswere used for analysis in this paper.

Figure 1 Age Hardening Process In the early stages of aging, a large number of very small clusters of the secondary Ө-phase are formed.
Positron annihilation has been intensively studied in metals and the reason for this is that the positron annihilation method makes it possible to determine such important characteristics of metals as the electron momentum distribution, the Fermi energy (usually measured in eV), the number of free electrons per metal atom, and the concentration of such electrons in the conduction band.
Firstly, we quenched it at 520oC and then aged it at two different temperatures (150 or 175oC) as seen in figures 4 and 5. 0 2 4 6 8 10 12 14 16 18 0 5 10 15 20 25 30 Anneling at(150) hardness(1050) lifetime(1050) Figure 1 Aging time (hour) after quenching at (520) Hv (number) 120 130 140 150 160 170 180 190 200 210 220 mean lifetime(ps) 0 2 4 6 8 10 12 14 16 18 0 5 10 15 20 25 30 Annealing at(150) Hardness(1050) Mean lifetime(1050) Figure 3 Aging time (hour) after quenching at (530) Hv (number) 120 130 140 150 160 170 180 190 200 210 220 Mean lifetime (ps) 0 2 4 6 8 10 12 14 16 18 10 20 30 40 50 60 70 anneling at(175) Hardness(6063) lifetime(6063) Figure 5 Aging time (hour) after quenching at (520) Hv 170 180 190 200 210 mean lifetime(ps) In Fig.4, the samples (6063) were quenched from 520oC into distilled water and then annealed at 150oC for various times.

It was observed through these two tests that, increase in ball milling time after 6 hours resulted in grain size reduction.
Initially premix or hand mixed [29] where the quantity of soil was divided into ten portions and each portion was spread in a square pan (50×50 cm) then the required amount of nanomaterial was sprayed using sieve number 200 as shown in Figure 6.
However, as shown in Figure 16, the intensities of peak corresponding to reflection vary after ball-milling and become broader, indicating the decrease of grain size of kaolinite particles due to the micro strain induced peak broadening.
After 1, 2 and 6 hrs. of milling, the sample still contained the three forms of elemental powders, but with further milling (24 hrs.), peaks were reduced, showing that increasing ball mill time after 6 hrs. led to grain size reduction.

Through the above steps, the matrix membrane has adsorbed a large number of platinum ions so as to significantly increase the stiffness of membrane.
With the addition of NaBH4 and the rose temperature, the color of basement membrane turn light brown from clear and yield large number of small bubbles absorbed on the surface, and the film turns to silver-white when the NaBH4 solution drops more than four times.

Especially, CaO-MgO-Al2O3-SiO2 (CMAS) systems made it possible to obtain glass-ceramic, where a diopside phase provided a main, and often single, crystalline phase that depending on fine- or coarse-grained structure could control hardness and wear-resistance of materials [3,4].
Since the growth of crystals occurred in the transient number of nuclei, the activation energy Ea, was determined by the modified Kissinger method respecting the crystallization mechanism according to the following formula [7]: (1) where: n – Avrami parameter connected with a crystallization mechanism, m – represents dimension of crystal.
As a result of phase transitions, distributions of metastable Na2CaSi3O8 and olivine phases, and an increase in the number of vitreous phases, the conditions for forming gahnite, for which the activation energy was determined as Ea=379kJ/mol, were facilitated.

In addition, in high pH conditions, the surface of the fly ash will gather a large number of negative charges, due to electrostatic repulsion effects making phosphate ion not easy to close to the surface of fly ash grain, which would also affect the fly ash on the phosphorus sorption capacity.
After acid treatment of fly ash that release a large number of Al3+ and Fe3+ can effectively reduce or eliminate the suspended particles in water potential, so the suspended particle is destabilizated, and acid treated fly ash particle surface will form a plurality of grooves and holes,that can enhance the adsorption of these destabilization of the colloidal particles.

Because only study the mechanism of mill asymmetric rolling, to analyze the vertical plate bending deformation in rolling process, taking into account the level of existing computer which not easy to calculate the model of total number of cell contacts more than 15,000, so the size of basic model of plate is taken as the width of only 20mm, while the length only 1200mm, inlet thickness 220mm, export thickness 200mm; The smallest unit is 7.5 (L) × 5 (width) × 7.5 (high) mm (see Figure 1a).
