Résumé:
We would like to express our special thanks of gratitude
to our teacher Dr CHETTIBI Taha who gave us the
golden opportunity to do this piece, which also helped us
in conducting this research. Secondly, we would also like
to thank our parents and friends who helped us a lot in
finalizing this work within the limited time frame.
We are overwhelmed in all humbleness and gratefulness
to acknowledge our depth to all those who helped us to
put this thesis together within its ideas, well above the
level of simplicity and into something concrete. With
God’s guidance and plenty of sleepless nights we present
this piece of art.
