Thereafter, (Allahverdi et al. 2008) [5] showed that the BFSP is NP-hard even for BFSP with m ≥2.
(Ribas et al. 2011) [16] introduced an iterated greedy (IG) algorithm.
(Han et al. 2012) [17] proposed an improved discrete artificial bee colony (IABC) algorithm for solving effectively the BFSP.
The proposed algorithms are compared to other forcful existing metaheuristics in the literature, namely, IABC( han et al. 2012) [17]), DE-ABC( han et al. 2015) [18], IG( Ribas et al.2011) (16], and MFFO ( han et al. 2016) [20].

For the calculation of thermal conductivity of solids are the most important two contributions: the heat transport by electrons (el) and by phonons (ph).
(2) Thus the partition function Z is a product of terms of the ground state (0), the translation (trans), the vibration (vib), the rotation (rot), the internal rotation (ir), the influence of electrons excitation (el), the influence of nuclei excitation (nuc) and the influence of the intermolecular potential energy (conf).
Comparisons with the computer simulation data indicate that the expressions developed yield better results (pressure, internal energy, free energy) than theory of Weeks at al. [7-9], Barker and Henderson [7-9].

In other applications, Zn-Mg alloys have been developed for use as protective metallic coatings on steels by Prosek et al. [3] and Yao et al. [4].
The results agree well with those reported by Prosek et al. [3] and Yao et al. [4].
The interlamellar spacing in the eutectic structure in the present study was about 0.60 mm, consistent with that reported by Yao et al. [4].

Similarly Egashira et al. demonstrated planetary motion of the rotating tool electrode for improved process efficiency [4].
Teicher et al. employed tool movement along a helix path for accurate electro discharge drilling of carbon fibre-reinforced plastics [5].
Similar observation has been reported by Dave et al. in their work [8].

Based on the results presented by Lord et al. [10], small variations at cooling rates can promote greater changes on microstructures of high strength steel weld metals.
In this respect, Ramirez [11] in agreement with Surian et al. [12], states that the weld metal strength increases with carbon equivalent number.
According to Surian et al. [12], it is well known that when selecting a C-Mn steel as an alloy base, in order to increase tensile strength it becomes necessary to add to the alloy base alloying elements such as Ni, Mo, and/or Cr, which will modify other properties as well.
