Recently, Arrazola, Garay, et al [6] researched about the machinability of Ti555.3 and Ti6Al4V using conventional cooling method and uncoated cemented carbide (grade K15, micrograin) tool.
Experimental set-up The tool wear experiments were carried out on titanium alloy Ti6Al4V, with 6 wt.% Al and 4 wt.% V content, under the following conditions: l Workpiece: Ti-6AL-4V bar, solution-treated and aged.
Al, T.
El Mansori: Wear.

Diaham et.al [10] studied the thickness effect of the PI thin film on its breakdown strength, and concluded that thicker PI film would result in lower average Vbd due to the increase of defects which could cause the PI film’s failure during experiment.
More recently, Luo et.al [11] investigated the breakdown strength of the PI thin film under different ambient humidity and their finding is that the breakdown field strength decreases linearly with the environment humidity increasing and the maximum Vbd can be reach 250kV/mm at a humidity of 30%.
By applied on PI film’s surface, Li et.al [13] improved Vbd of the PI thin film by applying fluorination treatment on the film surface.

Adachi et al. [6] proposed a future cast system with an evaluation of the similarity between the combined features using the Spearman rank correlation coefficient for the system.
Liu et al. [7] proposes an optimal scheme of feature selection for the fusion technique of speaker verification by Maximum Kullback-Leibler (MKL) Distance.
This optimal scheme has been in accordance with Murty et al.[11]’s conclusions.
