Therefore, in this paper to optimize the design of treatment options, based on two factors of consolidation degree and bearing capacity, but also refer to the following values problem of the design parameters derived from the engineering experience: ① The choice of pile diameter Small non-sand concrete pile diameter is generally used in 150~450 mm, in the choice of pile diameter, according to the geological and holling conditions, equipment conditions, etc. are often used in 250 ~350mm. ② The length of pile The values of pile length relate to engineering geological properties of the soil and building requirements of the settlement, and the size of the required capacity of single pile etc. pile generally should be located on the soil that has higher bearing capacity, length-diameter ratio greater than 20, but should not exceed 80; Common length- diameter ratio is normally 40 to 60. ③ The value of mobilization factorof single pile bearing capacity The size ofrelate to building requirements
of the settlement, the engineering less demanding on building settlement, the value of factor may take 1.4 to 1.6, otherwise take 1.2 to 1.4. ④The value of enhancement factor of bearing capacity of natural soil The size ofrelate to properties of the natural soil between piles, building requirements of the settlement, the size of area replacement ratio.
For the factor of well diameter ratio: , is the well diameter ratio, the relationship betweenandshown as following table 2.
For small non-sand concrete pile, because the pile diameter affected by the engineering geological conditions and drilling equipment, the scope of common values of pile diameter changes in lesser extent, can be considered as a constant, in this case, the trends of,andis consistent.
For the factor of smear and disturbance: , the impact on the ground consolidation mainly related to the factors of construction, but no direct relationship with the size of the pile spacing.

In engineering applications, a critical attribute of a component is often its geometry, particularly in mechanical systems such as power train and suspension applications.
Geometric properties of mechanical systems can often be captured through laser scanning, the outputs of which can be used to reverse engineer a digital model of the various components of the system.
This inevitably affects the ultimate accuracy of the data and, hence, the CAD model produced [12].
Specific benefit included: · Value-added activity is £2.4m.* · Reduction in “time to market” · Introduction to new process · Improvement in product quality · Increasing technical knowledge * The term can be defined as “value” is used to encompass factors including vehicle quality and craftsmanship and also address development process costs versus the capital costs of the models themselves [15].

Crack growth is intensely affected by residual stress how hardness and microstructure characteristics play the minor roles [1, 2, 4, 8, 20].
The FSW joint wascharacterized in terms of the residual stress, (using the hole drilling technique), material, and cyclic properties.
The simulation was conducted using linear elastic fracture mechanics based on Paris’ model, and the maximum tensile stress and displacement correlation methods were applied to calculate the crack direction and stress intensity factor, respectively.

The excellent mechanical properties of these alloys are attributed to specific deformation mechanisms, such as mechanical twinning and deformation induced martensitic transformations, the activation of which is controlled by the low stacking fault energy of austenite.
The temperature dependence of the recrystallization time (Fig. 2b) followed an Arrhenius-type relation (3) where QRX is the apparent activation enthalpy of recrystallization, and is the preexponential factor, i.e. the recrystallization time at infinite temperature.
In case of site saturated nucleation and non-constant growth rate, assuming a random distribution of nucleation sites and isotropic nucleus growth, the recrystallized volume fraction can be expressed as [12] (7) where N is the number of nuclei and f is a shape factor.
Both effects, recovery and reverse transformation to S-oriented austenite at the beginning of annealing affected the texture evolution in Fe-21.6Mn-0.38C alloy.
This indicates that the change in C content from 0.38% to 0.57% practically does not affect the texture development.

Furthermore, the same NafionÒ is expensive and is affected by some technical drawbacks, as the hydrogen crossover and poor stability at high temperature, so that new materials for membrane are investigated to lower the cost and improve the thermal and mechanical properties while maintaining the proton conductivity [29], as the hydrocarbon-based polymers [30], in particular, the cross-linked membrane type [31], or the radiation-grafted membranes [32]. 2.3 AEMs Anion-exchange membranes electrolysers have been drawing extensive academic and industrial attention as they do not employ rare and expensive metals for catalysts as well as expensive membranes with respect to PEMs [33], [34].
These two factors, dimension, and morphology, affect directly the thermo-mechanical stability of AEMs, as well as their efficiency, and they can be adjusted for different potential applications.
Nevertheless, an increasing AEM conductivity is generally associated with lower mechanical stability and higher water uptake in particular for thin membranes, thereafter, more research is needed in that sense [33], [35].
