  This study is concerned with the estimation of constant  and time-varying parameters in non-linear ordinary differential equations, which do not have analytical solutions. The estimation is done in a multi-stage method where constant and time-varying parameters are estimated in a straight sequential way from several stages. In the first stage, the model of the differential equations is converted to a regression model that includes the state variables with their derivatives and then the estimation of the state variables and their derivatives in a penalized splines method and compensating the estimations in the regression model. In the second stage, the pseudo- least squares method was used to es

اقيمت الكنائس على جانبي مدينة بغداد الغربي(الكرخ) والشرقي(الرصافة)، أما الأديرة فقد انشئت في موضع مدينة بغداد قبل بنائها وبعد البناء حافظ البعض منها على مكانته وانشئ البعض الآخر، في جانبيها الغربي(الكرخ) والشرقي(الرصافة)، وهو ما سنركز عليه في بحثنا عن كنائس وأديرة بغداد لمختلف الطوائف المسيحية فيها، فضلاً عن تسليط الضوء على دورها الإجتماعي والإقتصادي والثقافي، وإن كان محدوداً جداً وقاصراً على الأديرة أكثر

The art of synthesis is one of the most important pillars in cinematic art, as the director combines cinematic shots to produce a third shot in the mind of the recipient by various methods such as mental synthesis, analogous synthesis, rhythm synthesis, parallel synthesis and repetitive synthesis, Repetitive synthesis is one of the most important techniques in cinematic montage. Through repetitive synthesis, the director is able to link the shots and scenes with each other, and this is what we see in the poetic imagery of Adnan Al-Sayegh when he links the visual images to each other, especially those images that manifest the manifestations of grief and misery following the misfortunes that befell in His homeland. This study follows the d

The importance of earnings quality begin increase in recent year . Particulary after collapse the big companies in U.S.A When the Stock Prices of this Companies negative impact after reporting of transitory & unrealized earnings in the iterim reports , in the same time took to this earnings as absis of Future Predictions .

Many of acadmic researchers discusses empirical measures that used to assessments of earnings quality from the perspective of decision usefulness that represent core of FASB's conceptual Framework , and to the economic – based definition of earnings , developed by (Hicks) in 1939.

Tise research attempt to test som of earnings quality measures in commercial
