patience, and his deep comments. I admit that in spite of being fastidious, his rigorous method is very effective to make his students more professional researchers. I gratefully thank Mr. Anas Abou El Kalam, co-advisor of my thesis, who followed my first steps from the beginning of the thesis. He is a strong combatant who never gives up against any technical or administrative problem. By working with him, you find yourself obligated to be as productive as him to keep with his very active working rhythm
