قال احد المربين ( أعطوني طفولة سعيدة ممتلئة وخذوا شباباً ناضجاً سليماً) ويعني بالطفولة السعيدة تلك الطفولة المشبعة بالحب والحنان وتلبية الحاجات المهمة للطفل حيث يتعلم الطفل من احضان العائلة بعض النواهي والاوامر حتى اذا اتسعت دائرة معارفه شملت الرفقة والعصبة حيث يبدأ الطفل بالتحرر شيئاً فشيئأ من الضوابط العائلية وينتقل مركز ولائه واخلاصه من العائلة الى العصبية وكلما تتوسع علاقات الطفل تزداد خبراته وت

يعد القرن السابع الهجري /الثالث عشر ميلادي من أسوأ القرون التي عصفت بتاريخ أمتنا، وتمثل ذلك بالغزو الصليبي الذي كان في أوجه ومن ثم الغزو المغولي الهمجي الذي انهال على الأمة كما الجراد، أضيف لذلك ما كانت عليه الأحوال الداخلية من نزاعات بين الملوك والسلاطين، ورغم كل ذلك استطاع ثلة من العلماء الأكابر أن يدنوا التاريخ ويسطروه ليبقى محفوظاً للأجيال اللاحقة وصوناً لتراث الأمة العريق.

This paper addresses the use of adaptive sliding mode control for the servo actuator system with friction. The adaptive sliding mode control has several advantages over traditional sliding mode control method. Firstly, the magnitude of control effort is reduced to the minimal admissible level defined by the conditions for the sliding mode to exist. Secondly, the upper bounds of uncertainties are not required to be known in advance. Therefore, adaptive sliding mode control method can be effectively implemented. The numerical simulation via MATLAB 2014a for servo actuator system with friction is investigated to confirm the effectiveness of the proposed robust adaptive sliding mode control scheme. The results clarify, after

The Arab heritage is considered one of the treasures of the noble human civilizations, as it is a deep-rooted heritage, when the dawn of Islam dawned on the Arabian Peninsula, and when its conquests spanned,

The islamic caliphate was against the Aarab who became Muslims and
stayed in their desert and their companies didn’t share with the Muslims to
spread Islam by Al-Jihad. The Quran attacked them in many verses except
the Aarab who accepted when the prophet called them for Al-Jihad.
The Aarab in the ummayad period were in three categories :
1. The aarab who lived in the desert ,the islamic society was very revenge
towards them. The caliphate did not gave them Al-Ataa so they were in
bad situation
2. Those who lived in the country side . they were very trouble to the
trade.
3. The third lived in the cities and worked in the trade, Dawawin and in the
administration.
The Aarab of cities some of them associ
