Whereas the deduction level number of the first sheme is equal to the number of the basic geometries nbasic, the level number of the second sheme is much lower in general.
The level number nlevel can be determined by the following equation: nlevel = log2(nbasic) + 1, (3) where nlevel is the deduction level number and nbasic is number of basic geometries For example if the level number for the first sheme is nlevel = 32, the level number for the second sheme will be nlevel = 6.
Depending on multiple literatures specialized in studying the mechanical behaviour of this material the failure coefficient value of this diagram varies from 1.5 to 2.8 [18] according to the rolling temperature of this metal, grain size and other factures.

Many scholars made their contributions to the establishment of settlement influencing factors and settlement correction factors, put forward a number of linear or nonlinear relation equations, which may meet the real project situation quite well for a specific project. 
In the light of the characteristics of red clay subgrade, the settlement calculation is carried out separately using the following six calculation methods, i.e. the ES method and e-lgp method in the layerwise summation method, triaxial stress method, standard recommending method, secant modulus method, and field test method.  ③Comparing the calculated settlement and the measured settlement, the most suitable settlement calculation method for red clay subgrade will be selected and the settlement correction factors for various calculation methods can be obtained.  2 Work site profile Through site investigation and bore hole sampling on the work site DK1293, which is an untreated red clay cut section, the geology of this spot can be divided broadly: above the depth of 0.5m, the main component is vegetal soil consisting of hard plastic red brown clay; from 0.5 to 7.2m, hard plastic red clay is dominant, which shows a net striated structure and pale stripes, breccia with different grain diameter
Using the relationship between standard penetration test depth and the number of the blow of standard penetration, the relationship between compression modulus and the number of SPT can be obtained.
According to experience, there is a certain relationship between standard penetration test and loading test, i.e. the greater the number of blow of SPT, the greater the compression modulus.
The purpose of this formula is calculating compression modulus by using the number of blow of SPT, and then the settlement can be obtained by equation (7).

There are a large number of traditional communities in the heart of the old town, most of which are independent traditional courtyard-style shaped in Northern Hainan Island.
Dismantling the city to expand the streets during the Republican period, a considerable number of buildings overhang were converted in situ.
After several years, the traditional resident of northern Hainan behind the buildings overhang have experienced a number of renovation, alteration or reconstruction. 3.
The building density in the block is great, and a large number of houses are years old with a worrying status quo.
Protection can reflect the whole space scale of landscape features in this area, and extent the historical development grain of the city.

The apparent improvement at 0.1% is more likely to be a consequence of the poorly-understood and rather random nature of hot tearing, i.e. the variability in the number of castings that crack and the intensity with which they crack.
Table 2: Hot tearing results for the Al-Mg-Si base alloy with and without Cu additions Alloy Proportion of cracked bars Number of faces with crack severity rating: Mean (all bars) Standard error of means, e 0 1-3 4-6 Base 5/7 11 4 6 1.9 0.8 +0.1 wt% Cu 3/6 12 3 3 1.1 0.6 +0.2 wt% Cu 3/6 9 3 6 2.1 1.0 Figure 2: Plot of mean hot crack rating and standard error for the Al-Mg-Si alloy as a function of Cu.
The proportion of bars cracked, as well as the number of faces with individual crack ratings of zero, 1-3 or 4-6 are given, together with the mean values and standard error of means for each alloy variant.
Hot tearing is a complex phenomenon and there are multiple factors which can contribute to the incidence of hot tearing, including casting parameters, grain refiner level, sodium impurity and alloy effects.
One advantage of the use of the hot tear rig compared to an analysis of plant data, is that particular effects can be isolated and tested using a limited number of trials.

For improved decisions on the best materials and processes, the largest number of variables during the design phase should be considered.
These alloys are stronger than other high strength alloys, even when compared with Al-Li alloys, having a significant grain refinement, and exhibit good resistance to corrosion, [8].
The solution adopted by Boeing represented a dramatic shift from traditional airframe philosophy and creates a considerable number of new challenges.
From these data it is concluded that the structural design can be done for a pre-estimated number of cycles, depending on the design goal of the aircraft and its maintenance procedures.
Taking into account the assumptions presented, with CFRP a reduction in weight is achieved, of varying magnitude depending on the design goal (number of cycles) and maintenance procedures.

The hardness of alumina reinforcement is much higher than the hardness of the Al A356 matrix, with the increasing number of alumina reinforcement volume fraction then hardness properties of composite will increase as well.
The 2% volume fraction of alumina shown Fig. 4 appeared to have a less uniform dispersion of alumina, then the volume fraction of 15% alumina, Fig. 4 (f), seen a number of alumina agglomeration occurs.
While on spot 2, contains the numbers O dominant weight fraction, along with Al and Mg.
