Numbers of Neurons in Hidden Layer.
In order to optimize the network model, a number of topologies with different neurons numbers in hidden layer are tried in this paper in order to arrive at a topology which provides minimum effective error.
Comparing with errors, the optimum numbers of neurons are determined.
So the numbers of neurons in hidden layer are 11.
When the number of neurons hidden layer is 11, training error of network is 0.0171.

Presently known manufacturing methods of such items of equipment, for instance, stamping methods, have a number of technological problems.
Shear deformation and grain refinement in pure Al by asymmetric rolling.

Fr=the number of grains of the same sizethe total number of items measured×100 (2) Figure 3.
The IR spectra of the four samples have absorption peaks in wave numbers of 3410 and 3425 cm-1 and wave numbers at 1627.9 and 1636.6 cm-1 which with stretching mode for the O-H hydroxyl group on the nanocrystalline surface which creates molecular adsorption to the nanocrystalline surface [8,27].
From table 2 it can be seen that the NiZnFe2O4 material does not have a Ti-O-Ti functional group while the Figure 4 (c and d) material has a Ti-O-Ti functional group at wave numbers 1419 and 1404 cm-1, respectively [25].
However, after encapsulation, the wave number tends to shift to follow the smaller number, this indicates that it is between metal ions so that becomes weak [35].

Controlling the heat input during welding to maintain the mechanical properties is of special importance for fine-grained high-strength steels [17].
Fracture metallographic examination For the 5 stress levels with 4 specimens at each, the total number of specimens is 20.
The number of cycles up to 0.5 mm and 1.2 mm crack length is given in table 4.
The fatigue SN curve of notch stress range versus number of cycles at a=0.5 mm is constructed.
Even for a relatively limited number of specimens a fair life assessment is achieved.

Only a small number had failed, but they were extensively deployed across Europe. 8090-T8511 alloy.
Whilst there are a number of forensic engineering degree programmes and short courses in the UK, there does not appear to be an equivalent court-approved body to NAFE.
However, the number of such cases has risen dramatically in recent years and the relatively small pool of experts in any particular matter might be exhausted fairly quickly.
Liquid metal assisted cracking (LMAC) is a rare form of cracking which occurs in a number of specific cases where a liquid metal is in contact with a solid metal.
A number of failures of zinc plated carburettor bolts were experienced by a manufacturer.

A high concentration of lead in the soil can cause a number of toxic symptoms in plants, which can slow down growth, negatively affect photosynthesis (chlorosis), blackening of roots and various other symptoms.
Common wheat seeds (Triticum vulgare) were placed on the substrate, with 25 grains in each soil sample arranged in a square pattern measuring 5 x 5 cm.
Each plant is separated individually and placed in a container with distilled water, with the containers labeled according to the sample numbers.
The choice of statistical analysis methods and software depends on a number of factors, including the type of data, the purpose of the study, and available resources.
A significant number of scientists [18, 19] offer various ways of interpreting the value of the Pearson correlation coefficient.

The most important factors that determine the condition of the work material that can influence the outcome of the machinability are:[10] · Alloy chemistry, additions, · Morphology, size and volume fraction of the constituent phases, · Microstructure (grain refining and modification), · Porosity, · Heat treatment temper, and · Physical and mechanical properties.
The results demonstrate that the total cutting force and moment increases as the number of drilled holes increases.
Any increase in the Mg addition more than 0.1% to 319 alloys causes deterioration in tool life, higher cutting force and moment, and lower number of holes drilled.
Tool life results for different conditions of 356 and 319 alloys in terms of the number of holes drilled is listed in Table 3.
After a significant number of holes, the accumulation of aluminum continues and clearly reaches the drill lip.

Rosin [2] chiefly consists of different resin acids, especially abietic, pimaric acid and are not polymers like hydrocarbon resins but a blend of molecules characterised by three fused six-carbon rings, double bonds that vary in number, location and a single carboxylic acid group as in Figure 1.
This may be due to high epoxy functionality of the resins and the presence of the terminal glycol groups as indicated by the hydroxyl numbers of the prepared epoxy binders based on abietic acid and its ketone.
Moreover, the modification contributes to a notable improvement in the optical texture of resultant semi-cokes which varies from coarse-grained mosaics to domains.
In general, rosin–copper treatments increase the compression strength parallel to grain and Brinell hardness (BH) compared with controls, but the modulus of rupture (MOR) and modulus of elasticity (MOE) are lower than that of control.
Rosin–copper treatments also increase the compression strength parallel to grain (CSPG), BH on longitudinal and radial surface.

In comparison with FV method, FE method is more time consumption and need more memory; however, there are a considerable number of commercial FE software available in the market.
In accordance with explained, finite volumes method is the best solution to simulate the fluid flow in 3D printing, in particular, for problems with turbulent flows, i.e., high Reynolds number, and source term dominated flows. 5.1.
In order to ensure that the numerical results are independent of the mesh density, the number of elements sizes should varied until the simulation variables stay unaffected.
In the numerical simulation of 3D concrete printing based on Computational Fluid Dynamics there are a considerable number of meshing programs, available in literature, that could be used to enable grid quality measurement.
Devahastin, 3D extrusion-based printability evaluation of selected cereal grains by computational fluid dynamic simulation, J.

The significance of the effect on flexural strength was: cement sand ratio is greater than fiber content than steel slag powder content than fly ash content. 1 Introduction With the development of the economy, a large number of mining resources are extracted, most of the ores need to be beneficially processed after mining in order to be used as raw materials for smelting, and a large number of tailings will be discharged in the selection process [1].
A large number of tailings have not been timely and properly treated, which has brought some serious problems to the natural environment.
In the case of the same number of factors, the number of BBD tests is less than CCD, and the level of BBD test factors is limited to a certain range.
After molding the specimen in the temperature (20 ± 2) ℃, humidity 50 % ~ 60 % of the natural environment for 24 h after demolding, the specimen demolding numbered into the curing chamber.
