Praise be to God, Lord of the Worlds, and prayers and peace be upon our master and beloved Muhammad and all his family and companions. As for what follows:

The development in manufacturing computers from both (Hardware and Software) sides, make complicated robust estimators became computable and gave us new way of dealing with the data, when classical discriminant methods failed in achieving its optimal properties especially when data contains a percentage of outliers. Thus, the inability to have the minimum probability of misclassification. The research aim to compare robust estimators which are resistant to outlier influence like robust H estimator, robust S estimator and robust MCD estimator, also robustify misclassification probability with showing outlier influence on the percentage of misclassification when using classical methods. ,the other

 يعالج هذا البحث التوظيف الدلالي للمصادر في التعبير القرآني، وفيه يظهر أن أبنية المصادر ليست قوالب لفظية، تقتصر وظائفها على التعبير عن الحدث المعنوي الذي تتضمنه فحسب، وإنما هي بنية لغوية لها أفق دلاليّ واسع، حيث تمتزج بعناصر السياق وتتفاعل مع علاقاته التركيبية، فتؤدِّي وظائف دلالية متنوعة، يُبنى عليها كثير من المزايا البلاغية والأسلوبية.
