Fleschutz et al carried out the LCA (life cycle assessment) of assembly equipment and industrial robot and assessed their energy consumption during the usage stage [1].
Chen et al presented a green innovative design method based TRIZ to help designers develop energy-saving products [2].
Sutherland et al compared remanufacturing with new product manufacturing and proposed a method to determine the energy consumption of remanufacturing and its benefit [3].
Boustani et al [5] analyzed the life cycle energy consumption of typical appliances from raw materials, manufacture and use stage and got the life cycle energy demands of new product as shown in Fig.1.
For instance, cutting energy consumption (El) in machining mainly depends on machining power Pl

Meshless approximations have received much interest since Nayroles et al [42] proposed the
diffuse element method.
Later, Belyschko et al [43] and Liu et al [44] proposed element-free Galerkin method (EFGM) and reproducing kernel particle methods, respectively.
Recently, Atluri et al presented a family of Meshless methods, based on the Local weak Petrov-Galerkin formulation (MLPGs) for arbitrary partial differential equations [45] with moving least-square (MLS) approximation.

According to Balzar et al [24] naturally high beam collimation of synchroton provides a higher resolution.
Following Venkatesh et al [25], the dissipated energy during indentation is related to the ratio of the irreversible work Wir to total indentation work Wt given by the expression: r t ir E H 1 W W ⋅−= a where H, Er and α are hardness, reduced modulus and geometrical factor, respectively.

Characteristics of the System
The size of the system is taken into account to choose the daily water needs during the period of maximum need, which corresponds to the lowest maximum sunshine during the summer months.

Takahiro Ishizaki et al. [8] investigated the corrosion resistance of phosphate based conversion coatings formed on AZ31 magnesium alloy.
Magalhaes et al. [9] reported that the Mo (VI) ion was a localized corrosion inhibitor and it was also thought to allow self-repairing.
Their nominal compositions are 9.22 wt % Al, 0.72 wt % Zn, 0.418 wt % Mn and Mg balance.
