Control code is mainly for controlling the number of hidden nodes and the string length 1l are determined by 0.5-1.5 times of the number of input nodes, while the weight coefficient code is mainly the connection weight of the controlled network.

Murty: Prediction of grain size of Al-7Si Alloy by neural networks.

Grain moisture content, operating pressure, pressing temperature, and pressing time are factors that affect oil recovery from the pressing process [22]–[28]. 2.
Then the saponification number obtained by Gharsallah et al., (2021) is different from the saponification number in this study, which is 168.3 mg KOH/g oil.
The difference in the saponification number is due to several factors such as different hydrolysis process times, the effect of using different hydrolysis temperatures, and oil storage which also affect the saponification number of Moringa seed oil [16], [21], [35]. 3.4.3 Acid value of Moringa oil The acid value obtained in this study showed results that tended to increase with the addition of the pressing temperature, both with a moisture content of 8% Moringa seeds and a moisture content of 16% Moringa seeds.
The same results were also shown at pressing temperatures of 80oC, 100oC and 120oC with a moisture content of 16% Moringa seeds which produced an acid number which tended to increase when the pressing temperature was increased.
However, the acid number obtained in this study is still included in the standard acid number for edible oil according to FAO/WHO, namely the standard acid number of 2.89 ± 0.01 mg KOH/g oil [34]. 3.4.4 Peroxide value of Moringa oil The peroxide value of the oil represents the amount of peroxide found in the structure of a sample and which has the ability to liberate iodine I2 in an oxidative process by potassium iodide KI [36].

The nanostructured Al-based alloys composed by α-Al nano-grains embedded in an amorphous matrix show higher thermal stability and mechanical strength at room temperature than the fully amorphous alloys, moreover have three times greater mechanical strength than conventional Al alloys [2].
Therefore each pair of atoms (A-B) can be described, according its environment, by a sequence of four integer numbers.
The second number represents the quantity of shared neighbours (near-neighbours bonded with both A and B atoms).
These three numbers are not sufficient for characterising a topology, so a fourth number is added arbitrary but consistently for providing an unique correspondence between numbers and topologies [13].
As a normal behaviour it was observed that the total number of clusters increases as the temperature decreases.

Considering the opposite side of the phenomenon, a secured ignition, start-up and sustained combustion could only be obtained by providing a sufficiently high initial pressure and temperature around the propellant grain in the chamber, by means of an adequate ignition device, or igniter.
Most of these species are formed through thermal dissociation from a reduced number of main products, which are compulsory formed, regardless the dissociation, under the direct action of the law of masses.
From the action of the law of masses and simple stoichiometry the theoretical oxygen content in gram-atoms per unit mass of BP mixture AOt that would produces a complete combustion is equal to , (1) provided the number of sulfur gram-atoms is higher than half the number of potassium gram-atoms, . (2) This is the basic case.
When the theoretical oxygen content in the powder is not available, , (5) besides the main products of combustion given above a limited number of main products of incomplete combustion occur.
However, when the shift from the molar participations nj to the partial pressures pj is done, the additional variable π appears, as the still unknown ration between the total pressure and the total number of moles of gaseous products, , (7) where the total pressure pc is usually given and the total number of gaseous moles nG is still unknown.

Plot the histogram of gray image exported from profile filled with the color, gray level is between [0,255], the histogram is a discrete function , here,is the K-level gray degrees,is the number of the pixels with gray-scale level of.
The sharpness of the image is related with the number of pixels and resolution ratio; if pixels is a certain number of, the higher the resolution ratio, the image are more clear, and vice versa.
As Figure 4, by setting the coarse grid as 4 pixels, calculate the remainder of the total number of same pixels in the same region of this row, an integer used to divide the coarse grid; the remainder is used in the fine grid at the boundary

Ethanol is a solvent that can be also mixed with a number of other organic solvents, including acetic acid, acetone…).
The liquid depth was 2mm, the number of laser shots applied for the metal target at (50,100,150) pulses.
Show Figure (5-d) the extinction coefficient increases by increasing the number of laser pulses high values appear in the visible region.
This means that the metal transforming into semiconductor material and when grain size become smaller the optical energy gap increased this agree with [21].
