Previous work on Ni/Al– and Co/Al–LDHs synthesized by co-precipitation technique showed higher stability for the Ni/Al-LDH compared to that of Co/Al-LDH [8].

In 2003, on the basis of the studies of Hu et al.[12], Xu et al.[20] adopted an stepwise nonlinear programming method to solve the optimization problem of water-using networks with multiple impurities.
In 2007, Zheng et al.[21] improved the stepwise linear programming method that proposed by Hu et al.[12], so the efficiency for solving solution was improved.

In their review of damping studies related to composites, Chandra et al. [20] noted that there is a need to study damping in terms of its effect on stress or amplitude of vibration.
Case study and results The formulation was illustrated with a case study using data of a typical glass-vinylester composite (E0 = 1.1E10 N m-2, B = 1.5E7, ρ = 1940 kg m-3) which was tested by Daniel et al. [23].

Although, the idea of using a powder filled in a metal tube to which different steps of drawing, stacking and bundling are applied was suggested first by Tautzenberger et al . [20] and used recently to fabricate a copper-tungsten composite [21].
According to Chang et al
El-Badry, A.M.

Lee et al. [5] discussed the wall thickness of die casting parts, where different gate designs were adopted to detect the influence of molten metal flow in die casting parts.
Joseph HA et al. [5] used CAE software to simulate and analyze a gate and running system.
