The basic weldability of the alloy Al-2.2Li-2.7Cu was investigated and compared with two common aluminum alloys: 2024 and 5083. The basic weldability was characterized by the susceptibility of the alloy to hot tearing as determined by the trans-Varestraint test. The hot tearing susceptibility was characterized through plots of total crack length and maximum crack length versus augmented strain....

This paper describes the important significance of cutting-edge technology in machining polycrystalline diamond (PCD) cutting inserts by comparing evaluation criteria. The LASER is compared with grinding and electrical discharge (EDM) technologies. To evaluate data from experiments, Grey Relational Analysis (GRA) method was used to optimize input factors turning achieve required output paramete...

In this paper we introduce the SpeakCorrect system which is a Computer Aided Pronunciation Training (CAPT) system for native Arabic students of English. The system is designed with optimized performance for the target users group. It is L1 dependent system and only the frequent pronunciation errors of native Arabic speakers are examined. Several adaptation techniques such as Speaker Adaptive Tr...
