This article (Maoui et al. 2013) has been retracted by the Editor-in-Chief in consultation with the Publishing Editor, because parts of the Abstract, Introduction, Methodology, Fig. 4, and Conclusions were duplicated from a previously published article by Saibi et al. (2009). All authors agree to this retraction.
