As the bit rate of fiber optic transmission systems is increased to more than , the system will suffer from an important random phenomena, which is called polarization mode dispersion. This phenomenon contributes effectively to: increasing pulse width, power decreasing, time jittering, and shape distortion. The time jittering means that the pulse center will shift to left or right. So that, time jittering leads to interference between neighboring pulses. On the other hand, increasing bit period will prevent the possibility of sending high rates. In this paper, an accurate mathematical analysis to increase the rates of transmission, which contain all physical random variables that contribute to determine the transmission rates, is presen

هو ابو الحسن السري بن احمد السري الكندي الرفاء الموصلي ويعرف بالسري الرفاء وهو الاسم الذي غلب عليه، ولقب بالرفاء لانه كان يعمل في رفو الثياب وتطريزها وقد ذكره الثعالبي في اليتيمة فقال (فمنهم السري بن احمد الكندي المعروف بالرفاء)(1)ولد الرفاء في مدينة الموصل ولا تعرف سنة ولادته ولكنه من شعراء القرن الرابع الهجري الذين ذكرهم الثعالبي في يتيمته، وقد عاش صباه رفاء في سوق الرفائين في الموصل حيث سلمه والداه الى احد

Historic centers are often subject to urban renewal without the prior knowledge of the extent of the cohesion and attachment to place of its inhabitants. Identifying the rates of cohesion and place attachment can help urban designers to avoid decisions that lead to clashes with the reality of the social groups inhabiting the neighborhoods of the historic center. So the research aimed to measure cohesion and place attachment in a methodological approach based on a psychological instrument conducted by previous studies .The measurements were applied through a questionnaire given to the residents of six elected neighborhoods forming the historic center of Al- Adhamiya.The research assumed the relative disparity rates of cohesion and place atta
