The outputs of the ANN model include the ultimate tensile strength (UTS) of the test material.
Thermomechanical treatment is known to improve the mechanical properties of metallic materials.
Finally, an overview of the application of neural networks to study material science problems has been developed by Bhadeshia et al [22, 23].
In addition, it is expected that an increase in the yield strength YS (having a sensitivity factor of 2.30) involves an increase of tensile strength as they measure the resistance of test material (Fig. 7).

Third, changes in family composition and lifestyle promote changes in the use of space, construction techniques, and materials for traditional architecture, resulting in the loss of the original characteristics of traditional settlements.
In terms of preserving the Dong rural settlement, it is as serious as the changes in building materials and structure techniques.
However, changes in modern lifestyle have transformed the original homogeneous settlement continuum into hetero-buildings that feature different materials, construction techniques, and architectural forms (Fig. 9).

Compared with tower drum, latticed tower has less consumable, low transport costs, material consumption of latticed tower could be less about 40% than that of tower drum under the same height and stiffness, which can further reduce the cost of wind power.
