تقدير مصفوفة الحسابات القومية وتحديثها بإستخدام طريقة (C.E) دراسة مقارنة بين الطرق المستخدمة
...Show More Authors

ليس جديداً القول بان هناك حاجة مستمرة ومتزايدة لاستخدام البيانات الاقتصادية المتسقة عن القطاعات المختلفة في الاقتصاد القومي لدعم وإسناد عملية التحليل الاقتصادي وتطوير النماذج الاقتصادية الكلية.

وتعرض مصفوفة الحسابات القومية Social Accounting Matrix  (SAM) اطاراً شاملاً من المعلومات الأساسية لهذا النوع من النماذج والتحليل. فهي تتضمن كلا من المستخدم- المنتج
(جداول المدخلات- المخرجات) وحسابات الناتج والدخل القومي في اطار متناسق.

وبينما يتم اعداد جداول المستخدم – المنتج عادة مرة واحدة كل خمس سنوات او شيء من هذا القبيل، فان حسابات الناتج والدخل القومي تعد سنوياً وبتباطؤ زمني، أي لفترة زمنية سابقة. اما تحديث مصفوفة حسابات قومية لفترة لاحقة، فأنها لا تعد مسالة صعبة فحسب، وإنما تعد  مسالة تحدي.

ولتركيب مصفوفة حسابات قومية موسعة قابلة للتحليل الاقتصادي, فان البيانات المطلوبة هي من السعة بحيث يصعب توفيرها، وعند ذلك ينبغي ان تستكمل بواسطة معلومات اضافية ومن مصادر مختلفة، مثل الاحصاءات الصناعية، مسوحات العمل، البيانات الزراعية، الحسابات الحكومية، حسابات التجارة الخارجية، ومسوحات الاسر وغيرها. اما المشكلة الرئيسية في تحديث مصفوفة الحسابات القومية فانها تكمن في أيجاد طريقة كفوءة وقليلة الكلفة لدمج المعلومات المستحصلة من تلك المصادر والتوفيق بينها، بضمنها البيانات المستقاة من سنين سابقة.

ان الطريقة التقليدية لبناء مصفوفة حسابات قومية حديثة متماسكة ومتسقة، هي البدء من مصفوفة حسابات لسنة اساس معينة سابقة، ثم تحديثها لفترة لاحقة من خلال ادخال معلومات جديدة عن مجاميع الصفوف والاعمدة، لتلك المصفوفة مع بقاء المعلومات حول التدفقات الداخلية التي تتضمنها الـ ( SAM) ثابتة، وغالبا ما يتم البدء من مصفوفة حسابات غير متسقة ومعلومات غير متكاملة عن مجاميع الصفوف والاعمدة والتدفقات المختلفة في الـ (SAM).

Influence of Cold Plasma on Sesame Paste and the Nano Sesame Paste Based on Co-occurrence Matrix
...Show More Authors

The aim of the research is to investigate the effect of cold plasma on the bacteria grown on texture of sesame paste in its normal particle and nano particle size. Starting by using the image segmentation process depending on the threshold method, it is used to get rid of the reflection of the glass slides on which the sesame samples are placed.  The classification process implemented to separate the sesame paste texture from normal and abnormal texture. The abnormal texture appears when the bacteria has been grown on the sesame paste after being left for two days in the air, unsupervised k-mean classification process used to classify the infected region, the normal region and the treated region. The bacteria treated with cold plasma, t

An Analysis of Textual Themes in M.A Theses and Ph. D. Dissertations Written by Iraqi EFL Learners
...Show More Authors

The present study investigates the realization and significance of textual themes in the organizational structure of M.A theses and Ph.D. dissertations, namely: the abstracts, introductions and conclusions, since in such parts the students depend on their own expressions, styles and constructions to express different viewpoints, plans, inferences, etc. The study also investigates the similarities and differences between M.A theses and Ph.D. dissertations concerning the use of textual themes;it sets out to conduct a detailed analysis of textual themes used in such texts. In conducting such an analysis, the study adopts Halliday's (1994) approach of textual themes. The results of such an analysis have clearly shown that, in spite of the di

Wireless Network Control System for Electro Stati Precipitator in Cement Plants
...Show More Authors

    Wireless control networks (WCNs), based on distributed control systems of wireless sensor and actuator networks, integrate four technologies: control, computer network and wireless communications. Electrostatic precipitator (ESP) in cement plants reduces the emissions from rotary kiln by 99.8% approximately. It is an important thing to change the existing systems (wireline) to wireless because of dusty and hazardous environments. In this paper, we designed a wireless control system for ESP using Truetime 2 beta 6 simulator, depending on the mathematical model that have been built using identification toolbox of Matlab v7.1.1. We also study the effect ofusing wireless network on performance and stability of the closed l

Semi-Active Damping of Mechanical Vibrating Systems Using Variable Stiffness Actuator
...Show More Authors

      In this research, a variable stiffness actuator is proposed to enhance the damping of the mechanical vibrating system. The frequency response analysis of the vibrating system is dependant in order to analyze and synthesis this semi-active damping, where the suggested process is using active filter to estimate the present frequency of the vibration system, and this will limit the value of the stiffness of the vibrated system. Two active filter s are needed, low-pass-filter (LPF) to choose the higher stiffness of the actuator at small frequencies as well as more damping and high-pass-filter (HPF) to choose the lower stiffness of the actuator at high frequencies as well as more damping, and so
